693211-2 : CVE-2017-6168

Solution Article: K21905460


664063 : Azure displays failure for deployment of BIG-IP from a Resource Manager template

Component: TMOS

Symptoms:
When deploying BIG-IP images through Azure Resource Manager or Marketplace Solution templates, the Azure portal will never display success. A timeout will eventually occur and the deployment will appear to have failed.

Conditions:
Deployment from an Azure Resource Manager or Solution template, including the BIG-IP WAF Solution from the Azure Security Center.

Impact:
A successful deployment will appear to have failed when monitoring the status in the Azure portal.

Workaround:
None.

Fix:
Deployments of BIG-IP from Azure Resource Manager or Marketplace Solution templates, or the BIG-IP WAF Solution from the Azure Security Center, now show the correct deployment status.


660170-2 : tmm may crash at ~75% of VLAN failsafe timeout expiration

Solution Article: K28505910

Component: Local Traffic Manager

Symptoms:
When VLAN failsafe is configured, and the VLAN failsafe timeout is 3/4 expired, tmm wants to generate ICMP traffic to evoke a network response. When this occurs, the system might experience a crash.

Conditions:
- VLAN failsafe is configured on a VLAN, for example with the recommended VLAN failsafe timeout of 90 sec.
- The VLAN does not observe ARP/ndp traffic for 3/4 of the timeout, 67.5 seconds.
- ICMP traffic generated to provoke a network response can under certain circumstances cause a TMM crash.

Impact:
TMM crashes, failover is triggered, as it would with a fully expired VLAN-failsafe-timeout condition (note that failover with a fully expired VLAN failsafe is correct behavior).

Traffic on other VLANs might be disrupted while TMM restarts. (Traffic on the VLAN-failsafe-triggered VLAN is already disrupted, causing the timeout to expire.)

Workaround:
1. To allow for VLAN failsafe to be updated for any frame, run the following command with VLAN failsafe enabled, run the following command:
 tmsh modify failover.vlanfailsafe.resettimeronanyframe enable

This configuration increases the confidence that in the case of a timeout expiry a real traffic disruption is detected.

2. Set the timeout of VLAN failsafe to 4/3 of the setting you want, for example, to have a timeout setting of 90, specify 120. With this setting, failover occurs at 90 seconds for a fully quiescent network.

Note: Having a fully quiescent network is a rare occurrence and likely indicates that another issue is occurring anyway.

Fix:
Generating ICMP traffic from TMM is no longer exposed to a potential crash in an invalid configuration or a completely quiet network, when generating ICMP traffic to provoke a network response on an expiring timer of VLAN failsafe, assuming the following configuration:

- VLAN failsafe is configured.
- VLAN failsafe expired 3/4 of the configured timeout (e.g., 67.5 seconds of 90 seconds ).


658764 : Linux kernel lasthop driver memory issue

Component: TMOS

Symptoms:
BIG-IP lasthop kernel module may leak memory.

Conditions:
BIG-IP lasthop kernel driver may leak specific memory structures which may lead to OOM conditions.

Impact:
BIG-IP experiences OOM conditions and core system services are disrupted.

Fix:
Resolve memory leak in lasthop kernel module.


654368-1 : ClientSSL/ServerSSL profile does not report an error when a certain invalid CRL is associated with it when authentication is set to require

Component: Local Traffic Manager

Symptoms:
Error is not reported if the profile is associated with an invalid Certificate Revocation List (CRL) that is not signed by trusted CAs, if the CRL issuer has the same subject name as one of the certs in trusted CA.

Conditions:
This occurs when associating CRLs with virtual servers.

Impact:
Error is not reported for invalid CRL.

Workaround:
OpenSSL command can be used to check if the CRL is signed by trusted CA.

Fix:
Error is reported in TMM logs if the CRL is not signed by trusted CA.


652151 : Azure VE: Initialization improvement

Solution Article: K61757346


651627 : IP addresses may appear "Aggregated" in "COMMON" section of dashboard but not Aggregated when applying module-specific filter

Component: Application Visibility and Reporting

Symptoms:
Some IP addresses may appear as "Aggregated" in the "COMMON" section of the dashboard but not Aggregated when applying a module-specific filter.

This occurs because lack of memory space causes information to be aggregated in the "COMMON" section before being aggregated in the module-specific DB.

Conditions:
A lot of diverse traffic (for some module) from many IP addresses (for example) on a system with a small amount of memory allocated for AVR.

Impact:
User sees a specific number (x) of IP addresses upon landing on the dashboard with "Aggregated" IP addresses, but when selecting a module-specific filter, statistics show a number plus another number (x+y) IP addresses (that is, essentially not aggregated).

Workaround:
Provision more memory to AVR.

Fix:
With this fix, aggregation does not happen in COMMON before it happens in the specific module. This is correct behavior.


651476-1 : bigd may core on non-primary bigd when FQDN in use

Component: Local Traffic Manager

Symptoms:
When using FQDN node/pool member resolution, a non-primary bigd process may core under certain circumstances. A non-primary bigd is any process instance other than zero in a multi-bigd scenario, or any bigd process on a non-primary blade in a chassis.

Conditions:
FQDN is in use.

Impact:
bigd may core and be restarted in a loop, causing some monitor instances to not be serviced. This may cause node/pool member flapping, or may cause certain nodes or pool members to be effectively not monitored.

Workaround:
Use static IPs instead of FQDN for node/pool member address assignment.

Fix:
Known causes of the bug have been fixed.


651106-1 : memory leak on non-primary bigd with changing node IPs

Component: Local Traffic Manager

Symptoms:
On BIG-IP systems with the multiple blades, or a BIG-IP system with multiple bigd processes running (bigd.1, bigd.2, etc.), if the system has FQDN nodes configured, all secondary bigd processes will consume an unusually high amount of memory, and bigd cores may exist when the FQDN node IP addresses change frequently.

Conditions:
FQDN nodes configured on a system, and the system (as a whole) has multiple bigd processes running, either across multiple blades or multiple bigd instances on a single blade. As configuration changes are made to FQDN nodes causing IP addresses to change, bigd on the non-primary places memory consumption may be unusually high.

Impact:
bigd memory leak; possible bigd crash.

Workaround:
Mitigation: use static IP nodes and pool members rather than FQDN.


650450 : After upgrade to v13.0.0, users may be met with a javascript error on the logon page or other APM pages

Component: Access Policy Manager

Symptoms:
BIG-IP APM v13.0.0 has modified javascript to better handle more flexible session timeout parameters. This necessitated a modification in the timeout code in APM.

Unfortunately, that means that after upgrade, your users may receive a script error: 'APMSessionTimeout is undefined' when using the F5 Edge Client, or when using a browser that has the old code cached.

Conditions:
Upgrade to BIG-IP APM v13.0.0 with a login page or other Policy Item that presents a GUI to end users connecting using the F5 Edge Client or a browser with the previous version's timeout javascript code cached.

Impact:
Users receive confusing script errors in Edge Client or their web browser.

Workaround:
Use one of the following workarounds. Note: If possible, use the first one. Only perform the manual workaround if the first one is not possible.

-- Check the Knowledgebase Article (https://support.f5.com/csp/article/K91200585) to determine available fix versions, and then contact F5 Networks Technical Support to obtain any available Engineering Hotfix or version Hotfix to address this issue.

-- Perform this manual workaround:

First, locate the items such as Logon Page and add a '?13' after the include for session_check.js.
For example, the following steps:
1. Logon to the GUI as Admin.
2. Click Profiles/Policies :: Customization :: Advanced.
3. Navigate to your Access Policy.
4. Navigate to Access Policy, then to the page that has the issue, such as Logon Page.
Note: The page is "logon.inc" for a logon page.
5. Locate the following line:

<script language="JavaScript" src="/public/include/js/session_check.js" ></script>.

6. Insert ?13 after session_check.js in the script language line, for example:

<script language="JavaScript" src="/public/include/js/session_check.js?13" ></script>.

7. Click Save Draft.
8. Click Save.

Note: Using the specific text "13" in "?13" isn't critical; it just must be some text.

Fix:
End users with Edge Client or other browser no longer receive javascript errors.


649933-2 : Fragmented RADIUS messages may be dropped

Component: Service Provider

Symptoms:
Large RADIUS messages may be dropped when processed by iRules.

Conditions:
This occurs when a RADIUS message that exceeds 2048 bytes is processed by an iRule containing the RADIUS::avp command.

Impact:
The RADIUS message will be dropped, and an error will be logged that resembles:

Illegal argument (line 1) (line 1) invoked from within "RADIUS::avp 61 "integer""

Workaround:
Remove RADIUS::avp commands from iRules processing large messages, or ensure that no RADIUS client or server will send large messages.


649617-1 : qkview improvement for OVSDB management

Component: TMOS

Symptoms:
The user can configure ovsdb-server in the BIG-IP system to communicate with an OVSDB-capable controller.

If the user wants the BIG-IP system to connect to an OVSDB-capable controller via a SSL connection, the user needs to configure a certificate and a certificate key in the TMSH command "sys management-ovsdb". Later on, if the user invokes qkview to collect system information, the configured certificate key can be collected in qkview.

Conditions:
The following conditions need to be met:

- BIG-IP has the SDN services license.

- The TMSH command "sys management-ovsdb" is set to "enabled". Note that this is set to "disabled" by default.

- The TMSH command "sys management-ovsdb cert-key-file" is set to a certificate key. Note that this is set to "none" by default.

Impact:
If the user invokes qkview to collect system information, the certificate key configured in the command "sys management-ovsdb cert-key-file" will be collected in qkview.

Workaround:
If OVSDB management is currently set to "enabled" in the BIG-IP system, then the user can reset "sys management-ovsdb cert-file" and "sys management-ovsdb cert-key-file" to "none" before calling qkview to collect system information.

In general, if OVSDB management has ever been set to "enabled", the user with the bash shell access can check if the file /var/run/openvswitch/BIG-IP_ovs_cert_key exists and delete it before calling qkview to collect system information.

Fix:
The certificate key configured in the "sys management-ovsdb" will not be collected when invoking qkview.


649571-2 : Limits set in Server SSL Profile are not enforced if the server ignores BIG-IP's renegotiation ClientHello

Component: Local Traffic Manager

Symptoms:
The BIG-IP system does not act on the absence of renegotiation.

Conditions:
A BIG-IP system acts as TLS client, a TLS server ignores renegotiation request. Finite TLS session data or time limits are configured in Server SSL Profile on the BIG-IP system.

An example of such a TLS server is Apache/2.4.10 on Fedora Linux.

Impact:
Limits, such as data limits ("Renegotiate Size" in Server SSL) or time limits ("Renegotiate Period" in Server SSL) are not enforced with finite "Handshake Timeout".

Workaround:
None.

Fix:
BIG-IP system acting as TLS client (Server SSL Profile) now shuts down the connection if a TLS server did not continue with TLS renegotiation within "Handshake Timeout" seconds after the ClientHello, corresponding to the renegotiation initiation, was sent by the BIG-IP system.


649369-1 : DES, 3DES and HIGH cipher string includes/excludes wrong ciphers

Component: Local Traffic Manager

Symptoms:
When cipher string contains "DES", 3DES ciphers are also included. The keyword "3DES" does not impact the included/excluded ciphers. HIGH no longer includes 3DES ciphers.

Conditions:
Cipher string contains DES, 3DES and/or HIGH.

Impact:
Additional ciphers being offered to the client or ciphers not being omitted.

Behavior Change:
3DES ciphers moved from "high" to "medium".


649048 : SSLI statistic and Traffic classification statistic lost after upgrade

Component: Application Visibility and Reporting

Symptoms:
If you upgrade from 13.0 to 13.1 (or above), SSLI and traffic classification statistis will be lost.

Conditions:
This occurs when upgrading SSLI from version 13.0.0

Impact:
SSLI and traffic classification statistic will be lost.

Fix:
Fixed an issue with statistics being lost during upgrade.


648990-1 : Serverside SSL renegotiation does not occur after block cipher data limit is exceeded

Component: Local Traffic Manager

Symptoms:
If you have a virtual server with a serverssl profile configured that serves large (>2GB) files, you may see these errors in /var/log/ltm:

info tmm[17859]: 01260034:6: Block cipher data limit exceeded.

Conditions:
This occurs when a serverssl profile is in use, and the server-side traffic exceeds 2GB.

Impact:
Serverssl renegotiation does not occur, log message is displayed.


648867-1 : Kernel vulnerability: CVE-2017-6074

Solution Article: K82508682


648786-1 : TMM crashes when categorizing long URLs

Component: Traffic Classification Engine

Symptoms:
TMM crashes when categorizing long URLs.

Conditions:
URL categorization with long URLs.

Impact:
Traffic disrupted while tmm restarts.

Workaround:
None.

Fix:
TMM now can handle really long URLs for URL categorization.


648715-3 : BIG-IP i2x00 and ix4x00 platforms send LLDP, STP, and LACP PDUs with a VLAN tag of 0

Solution Article: K45001725

Component: Local Traffic Manager

Symptoms:
LACP, STP, and LLDP PDUs sent from either of the i2x00 or i4x00 platforms have a VLAN tag added to the PDU when they shouldn't.

Conditions:
Provision any of the three protocols: LLDP, STP, or LACP and the PDU sent by the BIG-IP will incorrectly have a VLAN tag with a tag-id of 0 added to the PDU.

Impact:
Some 3rd party devices may reject the packet. This will adversely affect operation of the affected protocol.

Workaround:
None.

Fix:
This release ensures that the VLAN tag is stripped before the PDU is sent onto the wire.


648056-3 : bcm56xxd core when configuring QinQ VLAN with vCMP provisioned.

Component: TMOS

Symptoms:
bcm56xxd constantly crashes, device goes off-line.

Conditions:
Reboot the system with QinQ VLANs configured and vCMP provisioned.

Impact:
Device goes off-line.

Workaround:
None.

Fix:
bcm56xxd no longer crashes when QinQ VLANs are configured and vCMP provisioned.


647962-1 : B2250: Interface is dropping traffic in passive mode

Component: Local Traffic Manager

Symptoms:
Passive mode is a new mode of operation introduced in BIG-IP version 13.0.0. In this mode of operation, the BIG-IP system processes data offline to detect DoS attacks and/or to collect HTTP analytics data, etc.

The results are reported by the BIG-IP system might not be accurate.

Conditions:
-- Device is operating on passive mode data.
-- VIPRION 2250 blade.

Impact:
This will impact BIG-IP system's ability to operate in passive mode.

Workaround:
None.

Fix:
Passive mode is now fully supported on the B2250.


646511-2 : BD crashes repeatedly after interrupted roll-forward upgrade

Component: Application Security Manager

Symptoms:
After roll-forward upgrade of version 12.1.x with ASM traffic data is interrupted, BD crashes repeatedly.

Conditions:
Roll-forward upgrade with ASM traffic data from version 12.1.x (with or without hotfixes) to any 12.1.x or later is interrupted by restart/reboot.

Impact:
BD crashes repeatedly on subsequent attempts to start ASM.

Workaround:
Disable roll-forward upgrade of ASM traffic data before upgrade:

tmsh modify sys db ucs.asm.traffic_data.save value disable

Fix:
ASM completes roll-forward upgrade with traffic data correctly, even after upgrade process is interrupted.


645805-2 : LACP PDUs generated by lacpd on i4x00/i2x00 platforms contain bad ethernet src mac address

Component: TMOS

Symptoms:
LACP PDUs generated by the 'lacpd' on the i4x00 & i2x00 platforms contain the wrong Ethernet source MAC address.

Conditions:
LACP configured on an trunk interface on i4x00 or i2x00 platforms.

Impact:
Some Cisco and Juniper switches discard these PDUs. They send PDUs as if the BIG-IP is not transmitting with a all-zeros 'Partner' section System ID. This renders LACP inoperable, and simply does nothing if the far end is configured for 'Passive'.

Fix:
Insure correct Source MAC address is inserted into the PDU.


645219 : Switching to native virtio driver

Component: TMOS

Symptoms:
UNIC is the default driver for virtio devices.

Conditions:
BIG-IP system with a virtio device.

Impact:
Native virtio driver won't be used by default. Therefore, the benefits of using native virtio driver, such as lower CPU utilization, higher throughput won't be available.

Workaround:
Native virtio can be used as follows:
1. Create /config/tmm_init.tcl if the file does not exist.
2. Append the following line in the file:
device driver vendor_dev 1af4:1000 virtio
3. bigstart restart tmm
4. Check if the driver in use is "virtio" after running the following command:
tmctl -dblade -i tmm/device_probed

Fix:
A DB variable has been provided with this fix to conveniently switch to native virtio driver.

To switch to native virtio driver, run the following commands:
1. tmsh modify sys db tmm.drivers.net.virtio value native
2. bigstart restart tmm

Use of virtio is recommended for data plane interface when there is a separate management interface.

Note: Do not switch to native virtio driver when single nic configuration is provisioned (management is also used as dataplane).


645203-1 : Configuration load fails after upgrade when a SAML SSO config object is put in a sync-only device group

Solution Article: K72361514

Component: Access Policy Manager

Symptoms:
Configuration load fails after upgrading BIG-IP from a previous version. The system posts an error similar to the following:

01070734:3: Configuration error: Invalid Devicegroup Reference. The sso_config_saml (/Common/Auth/<object>) requires apm_log_config (/Common/sso-log-setting-Notice) to be syncd to the same devices
Unexpected Error: Loading configuration process failed.

Conditions:
When a SAML SSO config object or a Form-Based SSO config object is configured in a folder and that folder is in a Sync-Only device group. When upgrading with the existing configuration, the configuration load will fail.

Impact:
The configuration does not load.

Workaround:
1. Disassociate the folder from Sync-Only device group using the following commands:
 
tmsh modify sys folder <folder name> device-group none
tmsh save sys config.
 
2. Upgrade and verify config loads.
 
3. Create log-setting in each folder.
 
root@(temp12)(cfg-sync In Sync (Sync Only))(/S1-green-P:Active)(/Common)(tmos)# cd <folder name>/
root@(temp12)(cfg-sync In Sync (Sync Only))(/S1-green-P:Active)(/Common/<folder name>)(tmos)# create apm log-setting sso-log-setting-Notice { access add { general-log { log-level { access-control notice } publisher sys-sso-access-publisher } } }

Repeat this step for each log level: Alert, Critical, Debug, Emergency, Error, Informational, Notice, Warning, and use the appropriate log level accordingly.

4. Modify SSO log-settings to use log-setting created under the folder (<folder name>), according to their previous log level before upgrading. For example,
 
root@(temp12)(cfg-sync In Sync (Sync Only))(/S1-green-P:Active)(/Common)(tmos)# modify apm sso saml <folder name>/<sso object name> apm-log-config <folder name>/sso-log-setting-Notice
 
5. Associate Sync-Only device group SO1 to folder, as shown in the following example:
 
root@(temp12)(cfg-sync In Sync (Sync Only))(/S1-green-P:Active)(/Common)(tmos)# modify sys folder <folder name>/ device-group <DG name>
 
6. Verify config load.

Fix:
Configuration load now completes successfully after upgrade when a SAML SSO config object is put in a sync-only device group.


644870 : Improvements of protocol for sending data to AppIQ offbox via TCP

Component: Application Visibility and Reporting

Symptoms:
BIG-IP fails to handle these cases:
1. One AppIQ node is down, and so TCP connection need to be established to another node in AppIQ.
2. All nodes are down, no TCP connection can be established. The number of retries in this case need to be limited per snapshot, so resources are not consumed on the BIG-IP side if AppIQ system is down (current logic is a retry to open connection for every message, need to have few retries per snapshot).

Conditions:
BIG-IP is configured to send statistics to offbox via TCP protocol.

Impact:
1. Data are not sent when they can be sent (to another AppIQ node)
2. BIG-IP resources are consumed by multiple number of reties.
3. When TCP connections can't be established the systen doesn't free connection file descriptors, so at some point the avrd process goes out of file descriptors.

Fix:
1. Added an ability to configure multiple AppIQ IP addresses in external text file /etc/avr/ecm_ip_list.cfg
2. For every type of messages (tmstat, stst snapshots, etc.) BIG-IP makes only 2 attempts to reconnect to every IP provided. If it can't establish connection it doesn't try to send the messages of this type.
3. File descriptors are freed after every not successful connection attempt.
4. An upgrade mechanism for /etc/avr/ecm_ip_list.cfg is implemented.

Behavior Change:
1. Added an ability to configure multiple AppIQ IP addresses in external text file /etc/avr/ecm_ip_list.cfg
2. For every type of messages (tmstat, stst snapshots, etc.) BIG-IP makes only 2 attempts to reconnect to every IP provided. If it can't establish connection it doesn't try to send the messages of this type.
3. File descriptors are freed after every not successful connection attempt.
4. An upgrade mechanism for /etc/avr/ecm_ip_list.cfg is implemented.


644855-1 : irules with commands which may suspend processing cannot be used with proactive bot defense

Component: Advanced Firewall Manager

Symptoms:
A request is dropped.

Conditions:
1. The proactive bot defense is assigned to the virtual.
2. An iRule which suspends processing is assigned to the virtual. (includes a command like the "after" commands")

For more information on which TCL commands park, see K12962: Some iRule commands temporarily suspend iRule processing, available at https://support.f5.com/csp/article/K12962

Impact:
All requests which issue the proactive bot defense and the iRule will get dropped.

Workaround:
N/A

Fix:
irules which suspends the execution won't cause a request drop when the proactive bot defense is assigned.


644817-1 : Unexpected behaviour during a DNS(GTM) server creation with wrong option in product field: nullGeneral database error.

Component: Global Traffic Manager (DNS)

Symptoms:
On a GSLB Server create page, in the Product dropdown, you are able to select a separator option which causes an error when pressing the Finished button.

Conditions:
This occurs when you pick the separator option "-----------" in the product dropdown.

Impact:
Null General Database error is thrown.

Workaround:
Avoid picking the separator option as GSLB Server product type.

Fix:
The separator option is now non-selectable.


644805 : Kernel.el7.2: BIG-IP VIPRION B4450 - ACPI complaints about unpopulated cpu cores

Component: TMOS

Symptoms:
Due to the way modern Intel Haswell CPU BIOSes are typically configured, the BIOS presents an ACPI table, which includes details for unpopulated CPU sockets and on each socket unpopulated CPU cores.

Note: This is not F5-platform-specific, as the same can be seen on many high-end servers.

For physical cpu socket#0 and socket#1, the actual number of CPUs is 24 per socket. The possible number of CPUs is 36 per socket. For unpopulated socket#2 and socket#3, the actual number of CPUs is 0. The symptom is dmesg output similar to the following:


[ 3.198255] ACPI: \_SB_.SCK0.CP18: failed to get CPU physical ID.
[ 3.198266] ACPI: \_SB_.SCK0.CP19: failed to get CPU physical ID.
[ 3.198276] ACPI: \_SB_.SCK0.CP1A: failed to get CPU physical ID.
[ 3.198286] ACPI: \_SB_.SCK0.CP1B: failed to get CPU physical ID.
[ 3.198296] ACPI: \_SB_.SCK0.CP1C: failed to get CPU physical ID.
[ 3.198306] ACPI: \_SB_.SCK0.CP1D: failed to get CPU physical ID.
[ 3.198316] ACPI: \_SB_.SCK0.CP1E: failed to get CPU physical ID.
[ 3.198326] ACPI: \_SB_.SCK0.CP1F: failed to get CPU physical ID.
[ 3.198336] ACPI: \_SB_.SCK0.CP20: failed to get CPU physical ID.
[ 3.198346] ACPI: \_SB_.SCK0.CP21: failed to get CPU physical ID.
[ 3.198356] ACPI: \_SB_.SCK0.CP22: failed to get CPU physical ID.
[ 3.198366] ACPI: \_SB_.SCK0.CP23: failed to get CPU physical ID.

...

The normal at-boot dmesg output should show 96 lines of output since the maximum populated would be 4 * 36 which is 144, but there are only 48 CPUs present.

Conditions:
Booting of BIG-IP 7.2 kernels on VIPRION B4450 blades will show this routinely at each boot.

Impact:
None. This is purely cosmetic output due to to how the BIOS is configured.

There is nothing functionally wrong; the messages are simply diagnostic output that appears in dmesg output. The messages can be safely ignored.

Workaround:
None.

Fix:
The system now silences the cosmetic 'failed to get CPU physical ID' messages for the Intel Haswell BIOS.


644490-2 : Finisar 100G LR4 values need to be revised in f5optics

Component: TMOS

Symptoms:
The original tuning values for the Finisar 100G LR4 optics don't support module tuning. You might see FCS errors.

Conditions:
FCS errors can be observed with the shipping Finisar 100G LR4 tuning values.

Impact:
Occasional packet loss at the 100G physical layer.

Workaround:
Use 100G SR4 optics modules on the link if possible.

Fix:
FCS errors no longer occur using the latest Finisar 100G LR4 tuning values.

For information on installing and using the latest f5optics package (build 48.0 or later) that contains these tuning values, see F5 Platforms: Accessories (https://support.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/f5-plat-accessories.html).


644112 : Permanent connections may be expired when endpoint becomes unreachable

Solution Article: K56150996

Component: Local Traffic Manager

Symptoms:
Permanent connections, such as those used between tunnel endpoints, can be deleted when the route to the remote endpoint is removed.

Conditions:
-- Permanent connection, such as a tunnel.
-- Routing updates, either from explicit static or dynamic routes, or modifying self IP addresses.

Impact:
Tunnel, or other affected connection, will not pass traffic.

Workaround:
Remove and re-add the affected connection: e.g., delete and re-configure tunnel.

Fix:
Routing updates can no longer lead to expired permanent connections.

643547-2 : APMD initialization may fail when large number of access policy agents are configured in access policies installed on BIG-IP

Solution Article: K43036745

Component: Access Policy Manager

Symptoms:
Requests to /my.policy are not getting HTTP responses.

Log file '/var/log/apm' contains large number of error messages about failed XML data creation:

err apmd[5076]: 01490207:3: SAML Agent XML thread specific data creation error: ERR_FAIL.

Conditions:
The BIG-IP system is used with APM provisioned, and there are a large number of access policy agents configured across all access policies.

The issue occurs only at APMD startup time, e.g., when the BIG-IP system is reloaded, a new image is installed, or the apmd service is manually restarted.

When issue happens /var/log/apm will contain a large number of similar error messages :

 err apmd[5076]: 01490207:3: SAML Agent XML thread specific data creation error: ERR_FAIL

Impact:
APMD will not able to process any requests.

Workaround:
For some configurations and platforms, you can use the following steps to recover:

- Remove all unused access policies (if applicable).
- Restart apmd.

Fix:
APMD initialization will no longer fail at XML initialization when a large number of access policies/agents are present in the configuration.


643404-1 : "tmsh system software status" does not display properly in a specific cc-mode situation

Solution Article: K30014507

Component: TMOS

Symptoms:
If software image verification is enabled, the system must first verify a software archive with a cryptographic signature file before using it. If that file is not available, the software change will (intentionally) not proceed. It is also intended that "tmsh system software status" will explain the condition. But instead, it shows "failed (reason unknown)"

Conditions:
Trying to initiate a software change, but there is no signature file available that corresponds to the selected software archive if any of the following is also true:
-- The system is in Common Criteria mode (db var Security.CommonCriteria).
-- The system is in FIPS compliance mode (db var security.fips140.compliance).
-- Signature checking is manually enabled (db var LiveInstall.CheckSig).

Impact:
It is difficult to ascertain why the software change cannot be made.

Workaround:
The installation logs a more detailed explanation for the failure. In the case of Common Criteria mode, it is essential to have the signature file in the same images directory as the .iso image you intend to install.

To do so, copy the .sig file from the F5 Downloads site to the image location, and try the installation again.

Fix:
The "tmsh system software status" now displays the relevant issue, for example:
failed (No signature verification possible for image /shared/images/BIG-IP-12.1.2.0.0.249.iso). Although you must still download the .sig file from F5 Downloads, it's clear what the failure is and what to do next.

Impact:
TMM memory leak or crash. Traffic disrupted while tmm restarts.

Workaround:
None.

Fix:
Fixed a memory leak in the FLOW_INIT iRule event.

Workaround:
N/A

Fix:
Health is now displayed for virtual servers as a textual representation of the condition, and attacks' severity follows the same pattern.


643328 : Activity Type filter is applied even when ASM is not used

Component: Application Visibility and Reporting

Symptoms:
When opening DoS Dashboard pages, Activity Type is automatically being applied to hide internal BIG-IP traffic. However, this classification exists only for Application Security, but not AFM.

Conditions:
ASM is not provisioned.

Impact:
Meaningless filtering is being done.

Workaround:
No workaround at this time.

Fix:
When ASM is not provisioned, the irrelevant Activity Type filter is not applied.


643327 : DoS Visibility Attacks Graph tooltip does not provide sufficient information

Component: Application Visibility and Reporting

643187-1 : BIND vulnerability CVE-2017-3135

Solution Article: K80533167


642983-2 : Update to max message size limit doesn't work sometimes

Solution Article: K94534313

Component: Device Management

Symptoms:
There is a cap on all REST request/response message size. By default it is set to 32 MB, and you can modify it to higher limit using /mgmt/shared/server/messaging/settings/8100 REST endpoint. But the REST framework may not apply this change.

When this occurs, you will see 501 Bad Gateway error from Apache and error message link "java.lang.IllegalArgumentException: 47177925 is more than 33554432" in restjavad log (/var/log/restjavad.0.log).

Conditions:
This can occur when requesting or receiving more than 32 MB of data via iControl REST.

Impact:
REST framework applies message body limit only on incoming request and response. If incoming request results in requests to iControl REST or restnoded, the same settings (message body limit) are not applied.

Workaround:
None.

Fix:
Messaging settings are applied on requests/responses, rather than on RestServer as forwarded outgoing requests/responses will not have server instance attached to request.


642926-1 : Increased MySQL Memory usage when APM is provisioned on lower-end systems.

Component: Access Policy Manager

Symptoms:
You may notice mysql process continuously consuming high amount of CPU and memory resources when APM is provisioned. This can be seen in the results of 'top' command where mysql will be continuously listed. The issue applies to BIG-IP with 32 GB or less system memory available.

Conditions:
When APM module is provisioned, if either of the following is true:
* logging configuration uses on-box publisher and log-level setting leads to high amount of logging data (e.g., DEBUG).
* LocalDB or OAuth Authorization server is configured with a DB instance and traffic is being processed.

Impact:
You may notice general performance issues on BIG-IP systems with system memory 32 GB or lower when MySQL usage is high.

Workaround:
1) Remove following 2 lines from file '/var/lib/mysql/cnf/apm.cnf' --
     innodb_buffer_pool_size = 1G
     sort_buffer_size = 256M
   and save file before exiting.
2) Restart MySQL service using -- 'bigstart restart mysql'

Fix:
MySQL configuration when APM is provisioned now works as expected on lower-memory BIG-IP systems.


642874-2 : Ready to be Enforced filter for Policy Signatures returns too many signatures

Solution Article: K15329152

Component: Application Security Manager

Symptoms:
Signatures that have not passed the staging period are shown when the filter is set to only show those that are ready to be enforced.

Conditions:
Signatures exist on a policy that have not passed their staging period and have no learning suggestions for them.

Impact:
Incorrect results are shown as a result of the filter.

Workaround:
The result should be inspected to see if the staging period has passed for each individual signature.

Fix:
The "Ready to be Enforced" filter works correctly.

642562 : TMM may crash with a very high number of concurrent TCP connections

Component: Advanced Firewall Manager

Symptoms:
TMM may crash with a very high number of concurrent connections (e.g., 30 million).

Conditions:
This happens if BIG-IP has a lot of concurrent connections and encounters HSB ring drops. At that time if ICMP monitors are configured, then LTM will QoS promote those ICMP monitor flows and if those are for the same endpoints, then tmm might crash.

Impact:
Traffic disrupted while tmm restarts.

Workaround:
None.

Fix:
TMM no longer crashes with a very high number of concurrent TCP connections.


642449 : Standard deviation for Request Duration is calculated incorrectly

Component: Application Visibility and Reporting

Symptoms:
In the HSL report, the Standard deviation for Request Duration is incorrect.

Conditions:
There are requests sent with delay reported in AVR reports.

Impact:
Wrong data in AVR reports. Standard deviation should be not 0 (zero), but it is reported as 0.

Workaround:
None.

Fix:
Fixed an issue with standard deviaiton calculation.


642400-3 : Path MTU discovery occasionally fails

Component: Local Traffic Manager

Symptoms:
Connections using a TCP profile that receive an ICMP needsfrag message may incorrectly ignore the message. This may cause Path MTU discovery to fail.

Conditions:
TCP profile assigned to VIP. Smaller MTU on data path than on TCP endpoints.

Impact:
The connection may stall as large TCP segments are continually retransmitted.

Workaround:
Configure the MSS in the TCP profile to match the lowest MSS. Use or disable Path MTU discovery with the tm.pathmtudiscovery database key.

Fix:
Path MTU discovery functions correctly with the TCP profile.


642330 : GTM Monitor with send/receive string containing double-quote may cause upgrade to fail.

Component: Global Traffic Manager

Symptoms:
When you upgrade from an affected version, the config gets saved before moving to the new version, thus dropping the enclosing quotes and causing a load failure when booting into the new version.

Conditions:
Configuration where monitor string contains \" (backslash double-quote) but does not contain one of the following characters: ' (single quote), | (pipe), { (open brace), } (close brace), ; (semicolon), # (hashtag), literal newline, or literal space.

Impact:
Configuration fails to load.

Workaround:
Manually edit each string in the BIG-IP_gtm.conf to include enclosing quotes in order to get the config to load the first time.

Fix:
Configs load successfully after upgrade. Surrounding quotes, if missing, are added to strings in the BIG-IP_gtm.conf file after upgrade. For example:
\"service_status\":\"on\".+\"maintenance\":\"off\" in the recv, send recv-disable and username fields. Output of list gtm monitor and bigip.conf match. Reloading the same config via tmsh does not cause unintentional changes, such as losing a level of escape in monitor strings.


642221-1 : Incorrect entity is used when exporting TCP analytics from GUI

Component: Application Visibility and Reporting

Symptoms:
When exporting statistics from the TCP Analytics page, the resulted data is for the default "view by" entity rather than the one that's actually selected

Conditions:
This occurs in Statistics :: Analytics : TCP, when you are viewing any dimension other than the default, and clicking Export.

Impact:
Incorrect data is being exported.

Workaround:
Use tmsh.

Fix:
The correct entity is now used when exporting TCP analytics from GUI, so the correct data is being exported.

NA

Fix:
iRule validation was improved to allow GENERICMESSAGE::message drop commands.


642124 : mixed statistics between two intervals

Component: Application Visibility and Reporting

Symptoms:
There are two collection intervals in AVR for collecting data: one every 10 sec for real time display and one every 5 min (or else set) for general statistics.
The 5 min statistics is accumulated from the 30 intervals of 10 seconds.
Sometimes, the last 10 seconds interval is missings the 5 min interval accumulation and entered the next 5 min interval resulting in an inaccurate accumulation of the 5 min interval.

Conditions:
This happens when the 10 seconds interval is taking too long to write it self

Impact:
Inaccurate accumulation of the 5 min interval statistics.

Workaround:
No workaround, some statistics will leak to next interval.

Fix:
The statistics for every 5 min interval will be display correctly (no leak between adjacent intervals).

641963 : Average CPU usage is calculated differently in DOS Visability page

Component: Application Visibility and Reporting

Symptoms:
On systems with HT Split CPU the Average CPU usage shown in DOS Visibility page was calculated as average of all available CPU-s. On other hand, on other screens it is calculated as an average of maximum of data plane and control plane CPU-s. It causes inconsistency in displayed data.

Conditions:
HT Split is enabled on the system (tmsh list sys db scheduler.splitplanes.ltm results in "True")

Impact:
Inconsistency in CPU usage values displayed in DOS Visibility and other screens

Fix:
After the fix on systems with HT Split average CPU usage is calculated only for data plane CPU-s. The GUI title is changed correspondingly.

Component: TMOS

Symptoms:
After upgrading, BIG-IP fails to load the configuration and reports that a monitor failed to load.

Conditions:
This can occur on upgrade, with specific backslash escaping in LTM monitors. Note: This issue is specific to LTM monitors. It does not occur in BIG-IP DNS monitors.

For example, to have two backslashes in the value, you specify three backslashes. The first backslash is the 'escape' character.

ltm monitor https /Common/my_https {
    adaptive disabled
    cipherlist DEFAULT:+SHA:+3DES:+kEDH
    compatibility enabled
    defaults-from /Common/https
    destination *:*
    interval 5
    ip-dscp 0
    recv "Test string"
    recv-disable \\\"Test\\\"me\\\" <-- pertinent string value (can be in recv, send or username attributes too).
    send Test
    time-until-up 0
    timeout 16
    username test\\\"me
}

Impact:
The monitor fails to load.

Workaround:
Manually correct the string to be the way it was before upgrade, then the configuration will load.

Fix:
Upgrade no longer results in incorrectly removing backslashes for some LTM monitor attributes.

-------------------------

Conditions:
-- ASM provisioned.
-- Local request logging enabled.
-- Upgrade of a maintenance release, hotfix, or engineering hotfix.

Impact:
Upgrade fails.

Workaround:
Upgrade by the means of saving a UCS, performing a clean install and then loading the UCS.

In the manual save/load UCS process, the upgrade of the Request Log can be disabled, which will workaround the error and the UCS will load fine.

There are two options to disable the upgrade of the Request Log, when upgrading by the means of a UCS:
-------------------
1) Do not load a Request Log, when loading a UCS:
    # tmsh modify sys db ucs.asm.traffic_data.load value never

2) Do not save a Request Log, when saving a UCS:
    # tmsh modify sys db ucs.asm.traffic_data.save value disable
-------------------

Fix:
Roll-forward upgrade including traffic data now works correctly.

Intra-chassis HA is configured. One of the blades goes down & comes back up very rapidly & some subscriber sessions are lost.
An attempt to add the lost subscriber again fails.

Impact:
A set of subscribers lost during HA will never be added back.

Workaround:
No workaround.


640376-2 : STPD leaks memory on 2000/4000/i2000/i4000 series

Solution Article: K46452834

Component: Local Traffic Manager

Symptoms:
STPD process on any 2000/4000/i2000/i4000 series platform that sends BPDUs will grow in physical memory usage indefinitely so long as its role in the tree results in sending BPDU packets. The memory usage will be faster for each interface that is sending BPDUs.

Conditions:
Spanning tree is enabled on any 2000/4000/i2000/i4000 series platform and the device has a role in the tree that results in sending BPDUs on one or more interfaces. Memory can be seen to increase when tracking with Linux top commands.

ex. top -b -n 1 | grep stpd

The 5th and 6th columns 'VIRT' and 'RES' slowly increase over time, indicating the memory leak.

Impact:
Memory leak resulting in indefinite consumption of available physical memory over time.

Workaround:
While the memory leak itself cannot be mitigated without a hotfix, the problem can be avoided if the tree can be configured in such a way that the defect affected platforms don't generate BPDUs. This can be done by choosing a root such that the defect affected platforms will have its interfaces to be in blocking mode, or if possible, to be in passthrough mode.

Fix:
BPDU process source code fixed to release memory allocated for each BPDU packet created and sent.


640352-1 : Connflow can be leaked when DHCP proxy in forwarding mode with giaddr set in DHCP renewal packet

Symptoms:
Connflow entry memory are leaked when BIG-IP DHCP proxy is configured in forwarding mode and the DHCP relay agent between
the DHCP client and the BIG-IP system sets giaddr field to itself after connflows created are aged out in a particular order.

Conditions:
1) BIG-IP DHCP proxy is configured in forwarding mode.
2) DHCP relay agent sits between the DHCP client and the BIG-IP system sets giaddr field in DHCP renewal packet to itself (this has been observed in Cisco devices), so that DHCP renewal packet will be sent to a relay agent by DHCP servers.
3) Connflow created to giaddr(relay agent) ages out before
connflows created to DHCP clients.

Impact:
Some connflows are not freed. Memory leak occurs. Eventually memory is exhausted.

Workaround:
None.

Fix:
Ref count handing for giaddr connflows are now decremented when the client side connflow is removed, preventing the memory leak.


639774-1 : mysqld.err rollover log files are not collected by qkview

Solution Article: K30598276

Component: TMOS

Symptoms:
Only the file /var/lib/mysql/mysqld.err is collected in qkview without truncation rules normally used for log files. Also, the mysqld.err.1 and mysqld.err.2.gz, etc are not collected at all.

Conditions:
This occurs when generating a qkview.

Impact:
You cannot see other mysqld.err rollover files in the qkview, and since the one mysqld.err file might be huge (larger than 2 GB) the output of qkview will be unusable.

Workaround:
The missing files must be manually copied into the qkview output. If the mysqld.err is greater than 2 GB in size, it must first be truncated to smaller than 2 GB.

Fix:
With this fix, the files /usr/lib/mysql/mysqld.err and associated rollover files (up through .7.gz) will be collected by qkview. Also the truncation/transformation rules that are used for log files will also apply (using -s <size> to modify default behavior), meaning that files greater than 5 MB (by default) will be truncated and there is a maximum limit of 75 MB for any given log file (using -s0).


639767-1 : Policy with Session Awareness Statuses may fail to export

Component: Application Security Manager

Symptoms:
ASM policy with many Session Awareness Statuses may fail to export.

Conditions:
There are many Session Awareness Statuses configured for the policy.

Impact:
ASM policy export will fail.

Workaround:
Remove all Session Awareness Statuses before export.

Fix:
ASM policy export only includes Session Awareness Statuses set to "Block All", and completes reliably.


639764-1 : Crash when searching external data-groups with records that do not have values

Component: Local Traffic Manager

Symptoms:
The TMM may crash when search through an external data-group that has at least one value with empty value.

Conditions:
For example, this occurs if data-group is defined as follows:
the key for network 10.40.0.0/13 has no value:
network 10.0.0.0/9 := "network 10.0.0.0/9",
network 10.40.0.0/13,
network 10.10.0.0/17 := "network 10.10.0.0/17",

A search in the data-group above with -value or -element options where at least one of the result records has no value will most likely result in a TMM crash.

Impact:
Traffic disrupted while tmm restarts.

Workaround:
Make sure that every record in the external data-groups has a value.

Fix:
Searching values in an external data-group where result will contain at least one value with an empty value no longer results in a TMM crash. A -value search will yield an empty string for the records that do not have a value.


639744-3 : Memory leak in STREAM::expression iRule

Solution Article: K84228882

Component: Local Traffic Manager

Symptoms:
If you are using the STREAM::expression iRule with APM, the stream filter can leak memory.

Conditions:
This can occur when using the STREAM::expression iRule with an APM virtual.

Impact:
This causes a memory leak in tmm.

Workaround:
None.

Fix:
This release fixes a memory leak in STREAM::expression iRule.


639729-1 : Request validation failure in AFM UI Policy Editor

Component: Advanced Firewall Manager

Symptoms:
A user of the AFM UI Policy Editor utility may see spurious results relating to firewall objects in the Firewall tab of the UI.

Conditions:
An authenticated UI user must attempt to manually modify firewall objects using the AFM UI URI endpoints.

Impact:
This impacts users as they interact with the AFM UI.


639630-1 : Searching for signatures with overrides in the policy returns incorrect results

Component: Application Security Manager

Symptoms:
1) Searching for Policy Attack Signatures with Overrides "On URLs" or "On HTTP headers" then all signatures are shown, regardless of whether they have overrides or not.
2) Searching for Policy Attack Signatures with Overrides "On XML profiles"/"On JSON profiles"/"On GWT profiles"/"On Plain Text profiles" then no signatures are shown, regardless of whether they have overrides or not.

Conditions:
Signature specific overrides are applied on URLs, Headers, or Content Profiles.

Impact:
No easy way to search for which signatures have overrides defined.

Workaround:
None.

Fix:
Searching for signatures with overrides now works correctly.


639575-2 : Using libtar with files larger than 2 GB will create an unusable tarball

Component: TMOS

Symptoms:
Programs such as qkview will create a .tar file (tarball) using libtar and if any of the files collected is greater than 2 GB, the output tar file cannot be read by /bin/tar.

Conditions:
The file collected via libtar (e.g., by qkview or other program dynamically linking with /usr/lib/libtar-1.2.11) is greater than 2 GB.

Impact:
You will be unable to submit a qkview to iHealth for analysis. Other applications using libtar will produce invalid tar files.

Workaround:
The qkview tarball can be extracted with /usr/bin/libtar, but the offending file will be a zero-length file. Alternatively, the offending file that is greater than 2 GB must be removed from the system prior to running qkview or other program that uses libtar.

Fix:
With the fix to 3rd party software, libtar, programs using libtar no longer create an unusable tarball when dealing with files larger than 2 GB.


639565 : Core when accessing MQTT::Type after drop

Component: Local Traffic Manager

Symptoms:
Core when accessing NULL MQTT::Type after drop.

Conditions:
iRule configured with NULL MQTT::Type and a MQTT::drop.

Impact:
tmm cores. Traffic disrupted while TMM restarts.

Workaround:
None.

Fix:
The system now logs a Tcl error when accessing a NULL MQTT::Type after drop, and performs the drop as expected.


639530 : Kernel.el7.2: xhci: off by one error in TRB DMA address boundary check

Component: TMOS

Symptoms:
Due to an off-by-one error in the xHCI driver, it is possible on BIG-IP platforms with xHCI controllers to
see the following dmesg output when booting an affected platform:

[ 164.552195] xhci_hcd 0000:00:14.0: ERROR Transfer event TRB DMA ptr not part of current TD ep_index 0 comp_code 1
[ 164.552200] xhci_hcd 0000:00:14.0: Looking for event-dma 00000000fffe6000 trb-start 00000000fffe7fe0 trb-end 00000000fffe8000 seg-start 00000000fffe7000 seg-end 00000000fffe7ff0

Conditions:
On any of the following BIG-IP platforms that have xHCI controllers and the system is booting normally:

- BIG-IP 5000/7000
- BIG-IP i2800/i4800
- HRC-i2800
- BIG-IP VIPRION 4450

Impact:
It is not clear what the impact is if nothing is connected to the USB 3.0 ports, which are not accessible except on BIG-IP VIPRION 4450.

Workaround:
None.

Fix:
Redhat integrated the fix for the off-by-one error from upstream kernel.org as part of the RHEL7.3 GA release, which is included in the BIG-IP 7.2 kernels in this release.


639528 : Kernel.el7.2: Broadwell Home Agent devices have non-compliant BAR.

Component: TMOS

Symptoms:
Broadwell-EP CPUs have UNCORE devices known as the "Broadwell Home Agent" devices.

For both single-socket and dual-socket platforms, this is pci 0000:ff:12.*.

These devices have non-compliant BAR's and when the systems with the Broadwell-EP CPUs boot, dmesg output includes as part of early kernel booting messages similar to the following:

[ 2.345303] pci 0000:ff:12.0: BAR 2: failed to assign [mem size 0x00000040]
[ 2.345306] pci 0000:ff:12.0: BAR 4: failed to assign [mem size 0x00000040]
[ 2.345309] pci 0000:ff:12.0: BAR 1: failed to assign [mem size 0x00000010]
[ 2.345312] pci 0000:ff:12.0: BAR 3: failed to assign [mem size 0x00000010]
[ 2.345315] pci 0000:ff:12.0: BAR 5: failed to assign [mem size 0x00000010]

Not related, but also seen is the following:

[ 20.123776] mei_me 0000:00:16.0: initialization failed.

This is due to the bios configuration not permitting access to the ME (Management Engine). The kernel module for the ME should not be loaded as a result.

Conditions:
Affects the following platforms:

- BIG-IP i10600/i10800
- BIG-IP i7600/i7800
- BIG-IP i5600/i5800
- BIG-IP i4600/i4800
- BIG-IP i2600/i2800
- HRC-i2800
- HRC-i5800
- HRC-i10800

Impact:
None. This is cosmetic and should not be cause for alarm.
The Broadwell-EP Home Agent devices are not used by BIG-IP software, and appear only as part of the UNCORE devices
associated with each physical socket.

Workaround:
None needed: this is cosmetic.

Fix:
This release includes RHEL7.3 kernels in the BIG-IP 7.2 kernels. RHEL7.3 kernels adds PCI handling for the Broadwell-EP Home Agent devices, which informs the kernel to not attempt to probe or configure the PCI BARs for such devices.

Also, this release disables loading the MEI driver, which prevents the mei_me message posting.

Conditions:
Creating virtual server with wild card destination, no net mask, and translate-address set to enabled.

Impact:
translate-address can only be set to disabled during creation.

Workaround:
Either set translate-address after creation, or specify net mask for virtual server creation.

Fix:
Translate-address flag will now be honored when set while creating virtual server.


638967-2 : SSL Forward Proxy not to cache forged certificate if soft_vfyresult indicating an 'untrusted CA' or 'expired cert'

Component: Local Traffic Manager

Symptoms:
The system caches a forged certificate when Forward Proxy (FWDP) server-side soft_vfyresult shows an untrusted CA or an expired cert. There is no method of overriding that behavior.

Conditions:
Using FWDP.
Server-side soft_vfyresult shows an untrusted CA or an expired cert.

Impact:
No method to override the caching behavior.

Workaround:
None.

Fix:
In this release, you can configure SSL forward proxy to not cache the forged certificate on the client side if the server-side SSL enables the sys db variable tmm.ssl.servercert_softval and the backend server certificate soft verify_result showing a 'untrusted CA' or 'expired certificate'.

Behavior Change:
In this release, you can configure SSL forward proxy to not cache the forged certificate on the client side if the server-side SSL enables the sys db variable tmm.ssl.servercert_softval and the backend server certificate soft verify_result showing a 'untrusted CA' or 'expired certificate'.


638838 : Dynamic Signatures are not copied to peers in a device group

Component: Advanced Firewall Manager

Symptoms:
During a failover event, a newly active BIG-IP will generate its own Dynamic Signatures rather than use a copy of the previous Active unit's signatures.

Conditions:
HA configuration with Dynamic Signatures enabled.

Impact:
During failover events, there will be a lag of a few seconds while the Dynamic Signatures are generated and collated.

Workaround:
1. Use the following command to verify that the device-group is set to none:
 list sys folder dos-common

2. If it is, you can associate dos-common to device group dos-global-dg using the following command:
 tmsh modify sys folder dos-common/ device-group dos-global-dg

3. Save the config using the following command:
 tmsh save sys config

Fix:
The system now explicitly adds folder and device group association, so the issue no longer occurs.


638825-1 : SNMP Get of sysInterfaceMediaActiveSpeed returns wrong value for 100000SR4-FD

Component: TMOS

Symptoms:
Value returned for sysInterfaceMediaActiveSpeed OID has value of 80 for interface with type 100000SR4-FD instead of value of 100000.

Conditions:
This always occurs for this type of interface.

Impact:
User sees wrong value for this interface in SNMP get. Value is correct in tmsh 'show net interface'.

Workaround:
Use tmsh to obtain the value by running the following command: show net interface. Note: There is no workaround in SNMP.


638799-2 : Per-request policy branch expression evaluation fails

Component: Access Policy Manager

Symptoms:
Per-request policy branch expression evaluation fails and you see the following in /var/log/ltm:

info tmm[20278]: 01870007:6: /Common/<policy>:Common:640446c9: Executed expression (expr { [mcget {perflow.category_lookup.failure}] == 1 || [mcget {perflow.response_analytics.failure}] == 1 }) from policy item (Category Lookup) with return value (Failed)

Conditions:
Per-request policy branch expression evaluation fails for any non-Access (non-APM) iRule events that are attached to the virtual server.


The evaluation does not trigger for some requests when, in the same connection, the virtual server gets a request for an internal Access whitelisted URL, and then request for backend resource URIs.

Impact:
Per-request policy branch expression evaluation fails. If Access gets a request for whitelisted URL, the system disables all iRule events except the following:

   #define ACCESS_ALLOWED_IRULE_EVENTS ( \
       ((UINT64)1 << TCLRULE_ACCESS_SESSION_STARTED) | \
       ((UINT64)1 << TCLRULE_ACCESS_SESSION_CLOSED) | \
       ((UINT64)1 << TCLRULE_ACCESS_POLICY_AGENT_EVENT) | \
       ((UINT64)1 << TCLRULE_ACCESS_POLICY_COMPLETED))

Workaround:
None.

Fix:
Per-request policy branch expression evaluation now complete successfully for non-Access (non-APM) iRule events that are attached to the virtual server.

This occurs when users in the Manager role make changes to Datacenter links/servers/prober-pool/Topology.

Impact:
The system posts generic validation errors when Create, Update, Delete actions are initiated by a user without proper permissions. These permissions are not allowed for the Manager, but the GUI makes it appear as if they are.

Workaround:
None.

Fix:
The GUI now properly hides or disables the action buttons if a user does not have proper permissions to perform the action.

636520-1 : Detail missing from power supply 'Bad' status log messages

Solution Article: K88813435

Component: TMOS

Symptoms:
When an internal hardware sensor alert is received indicating a 'Bad' power supply status, no detail is included which indicates which characteristic of the power supply's state is resulting in a 'Bad' overall status for the power supply.
In this scenario, the message logged at default logging level contains information similar to the following:
... crit chmand[...]: 012a0013:2: Blade 0 hardware sensor critical alarm: Power Supply 2 GPIO status(SPAFFIV03G): Bad

Conditions:
This occurs when the system posts an internal hardware sensor alert.

Impact:
Unable to diagnose cause of 'Bad' power supply status at default logging level to determine whether the probable cause is due to a power supply hardware fault or a possible external power source issue.

Workaround:
If power supply errors continue to be logged:

1. Set the libhal logging level to 'Debug':
tmsh mod sys db log.libhal.level { value "Debug" }

2. Let the system run in this configuration for at least a few minutes to collect a number of chmand error logs, such as:
... debug chmand[...]: 012a0007:7: Power Supply 1 alert objid:0x16f local:1 status:0x3 pin:0x2 action:0xd
... debug chmand[...]: 012a0007:7: Received Sensor Alert: sensor id 0x16f slot 0xff
... debug chmand[...]: 012a0007:7: Power Supply 1 alert objid:0x16f local:1 status:0x1 pin:0x2 action:0x3.

3. Set the libhal logging level back to 'Notice':
tmsh mod sys db log.libhal.level { value "Notice" }

4. Take a qkview or an archive of /var/log/ltm, and engage F5 Professional Services for further analysis.

Fix:
When an internal hardware sensor alert is received indicating a 'Bad' power supply status, additional detail is now logged to help identify the cause of the 'Bad' overall status for the power supply.


636479 : Hyper-V VE image fails to boot, stuck on "monpd: - Running monpd bigstart script." displayed on console at startup

Component: TMOS

Symptoms:

636289-1 : Fixed a memory issue while handling TCP::congestion iRule

Component: Local Traffic Manager

Symptoms:
Increased memory usage in tmm.

Conditions:
TCP::congestion highspeed iRule is executed for the TCP connection. The issue is only observed for highspeed congestion control.

Impact:
The memory allocated for congestion control is not freed.

Workaround:
If it is desired to use highspeed congestion control under some conditions, it is possible to start with highspeed by choosing highspeed congestion control in the TCP profile and switch to other desired congestion control when condition does not hold. With this workaround, once congestion control is changed to something other than highspeed, it is not possible to switch back to highspeed again.

Fix:
Improved memory utilization while using TCP::congestion iRule.


636155 : Countries table bottom rows are hidden

Component: Application Visibility and Reporting

Symptoms:
When "Ignored filters" message appears for the Countries widget on DoS Visibility screen, scrolling to the bottom of the list is impossible since the bottom-most rows are hidden.

Conditions:
This can be seen on the DoS Visibility screen when scrolling to the bottom of the list.

Impact:
The country at the end of the table is not visible.

Workaround:
Change sorting from Descending to Ascending to view the list in reverse

Fix:
All rows are displayed regardless of what else is on the page


636044-2 : Large number of glob patterns affects custom category lookup performance

Component: Access Policy Manager

Symptoms:
The number of glob patterns in a custom category linearly affects custom category lookup compute times. For example, twice as many glob patterns will roughly double the CPU resources required to compute a match.

Conditions:
A large number of custom category glob patterns. The precise number is not so important as the observed effect of slow response times. However, more than 1000 glob patterns is known to cause a significant observed performance degradation.

Impact:
Slow response times to HTTP requests.

Workaround:
It may be possible to compress the large collection of glob patterns into fewer patterns.


636016 : VADC: when using an Intel XL710 SR-IOV nic a bigstart restart can re-order the interfaces and impact traffic

Component: TMOS

Symptoms:
After a bigstart restart, traffic no longer flows because interface ordering can change.

Conditions:
A Virtual Edition configuration with more than one XL710 SR-IOV interface.

Impact:
The VLANs will be assigned to the wrong interfaces, network traffic is blocked.

Workaround:
If VLANs do not exist or the config is not saved before bigstart restart, there is nothing to be done except assigning the right VLAN to the desired interface (1.X) after restart. The MAC address of interfaces can be used to identify the desired interface.

If a config with VLANs is saved before bigstart restart, run the following command:
-- bigstart stop (this brings the data plane ethX devices down)
-- f5-swap-eth -s (this reassigns the interfaces)
-- bigstart start (this restarts the system).

Or you can reboot the guest.

635754-2 : Wildcard URL pattern match works inncorectly in Traffic Learning

Solution Article: K65531575

Component: Application Security Manager

Symptoms:
In the policy with URL learning mode set to ALWAYS, wildcard URL matching for *.[Pp][Nn][Gg]", "*.[Jj][Pp][Gg]", "*.[Gg][Ii][Ff]" will prevent you from adding other wildcard destinations using policy builder.

Conditions:
Policy builder enabled. PolicyBuilder creates the wildcard urls "*.[Pp][Nn][Gg]", "*.[Jj][Pp][Gg]", "*.[Gg][Ii][Ff]".
If you need to manually create another wildcard url "/polo/images/*", the pattern match will be incorrect and you will not be able to accept the learning suggestion.

Impact:
You will not be able to accept the learning suggestion to the correct wildcard URL.

Workaround:
In order to get suggestions on the correct wildcard match, remove "png" from the URL list in the policy: To do so, navigate to Security :: Application Security :: Policy Building :: Learning and Blocking Settings :: URLs :: File types for which wildcard HTTP URLs will be configured (e.g., *.jpg).

Also make sure that you have correct wildcard order. Go to
Security :: Application Security :: URLs :: Wildcards Order :: HTTP URLs.

"/polo/images/*" should be above "*.[Pp][Nn][Gg]" in the list. If it is not, move it using "Up" button".

Fix:
Wildcard URL pattern match now works as expected in Traffic Learning

635116-3 : Memory leak when using replicated remote high-speed logging.

Component: TMOS

Symptoms:
As a result of a known issue when a system uses a High Speed Logging (HSL) configuration with replication across the HSL pool TMM may leak memory.

Conditions:
Remote HSL setup with distribution set to replicated in the log destination configuration.
More than one poolmember, and one of them becomes unavailable.

Impact:
TMM will leak memory at a rate proportional to the amount of logging.
Over time this may cause an outage should TMM run out of memory.

Workaround:
Do not use replication in the HSL destination configuration.

Fix:
TMM no longer leaks memory when using a replicated HSL setup.

634132 : VE: virtio high performance driver (Linux/KVM)

Component: TMOS

Symptoms:
By default, the UNIC driver is used for virtio devices on Linux/KVM hypervisors, and at higher network speeds, the soft IRQ interrupt load competes with tmm. This can be observed under load with the "top" linux command showing ksoftirqd soft IRQ load.

Conditions:
Version 13.0.0 default behavior on Linux/KVM hypervisor with virtio nic(s) presented to the guest.

Note: To determine what driver is in use for each nic, use following command: tmctl -d blade tmm/device_probed.

Impact:
Potential performance issues (CPU utilization, throughput, connections/second).

Workaround:
None.

Fix:
For higher performance with virtio nics (relevant on Linux/KVM hypervisors), a new sys db variable supports switching to a TMM native driver.


634085-1 : IPsec tmm assert "ike_ctx tag"

Component: TMOS

Symptoms:
The tmm asserts with the message "ike_ctx tag."

Conditions:
It looks to be happening only on VE with ikev2 and ipv4, and the probable cause is timing related corruptions.

Impact:
Traffic disrupted while tmm restarts.

Fix:
The "ike_ctx tag" assert was replaced with an OOPS and the system logs the error and continues.


633985-1 : CS challenged URL is rejected on complex CPM/irule configurations

Component: Application Security Manager

Symptoms:
A request is rejected.

633879-2 : Fix IKEv1 md5 phase1 hash algorithm so config takes effect

Component: TMOS

Symptoms:
BIG-IP does not recognize the choice of md5 as hash algorithm in phase1 negotiation for IKEv1, but the GUI indicates it is available and configured.

Conditions:
Using either the command line or web UI to change hash algorithm to md5 in IKEv1 phase1.

Impact:
You are unable to configure md5 as hash algorithm in IKEv1, despite the UI and command line indicating this as an option.

Workaround:
You may be able to select md5, then save and then restart, this would set up the daemon from a config file instead of via incremental config parsing. So while it would not work right after being changed in the UI, the md5 option may work after a restart.

Fix:
The choice of md5 for hash algorithm now works correctly and immediately for an IKEv1 peer. The message causing this is now parsed correctly so md5 is recognized and used.


633723-4 : New diagnostics run when a crypto HA failure occurs and crypto.ha.action is reboot

Component: Local Traffic Manager

Symptoms:
A new db variable has been added to print diagnostic information when Cavium Nitrox devices encounter a "request queue stuck" error.

Conditions:
A Cavium Nitrox "request queue stuck" error occurs and the db variable "crypto.ha.action" is set to reboot.

I.e., when log message such as:
Feb 27 07:39:07 localhost crit tmm1[19936]: 01010260:2: Hardware Error(Co-Processor): cn1 request queue stuck

Impact:
Under the above conditions, the system will automatically run "nitrox_diag" to collect diagnostic information to help F5 determine the cause of the queue stuck error before rebooting.

The system will immediately failover to the standby system, but will then spend approximately one minute gathering diagnostic information beffore rebooting.

See https://support.f5.com/csp/article/K95944198 for more information about nitrox_diag.

Behavior Change:
Under rare conditions, the system will take approximately one additional minute to reboot.

If a Cavium Nitrox "request queue stuck" error occurs and the db variable "crypto.ha.action" is set to reboot, the system will automatically run "nitrox_diag" to collect diagnostic information to help F5 determine the cause of the queue stuck error before rebooting.

When the error happens, failover to the standby system will still happen immediately. The delay is only on rebooting the system which has already gone to standby mode.


633564-1 : Route unavailable when static route depends on another static route

Component: Local Traffic Manager

Symptoms:
Static route on the BIG-IP becomes unavailable after TMM restart, even though it's configured, and shows up in "list net route".

Conditions:
This occurs after restart, when a static route exists that depends on another static route. For example, a gateway route depends on an interface route.

Impact:
Route unavailable for use, traffic depends on the route is dropped if there are no alternate routes.

Workaround:
Removed the broken static route, and re-add it again.

Fix:
Route inter-dependencies no longer cause static routes to be unavailable after restart.

Impact:
There is an "Error parsing IP address" messave at the top of the page. You cannot modify internal data groups using GUI. You can delete and re-create the entry, but cannot modify it.

Workaround:
Use tmsh to modify the record field of the data groups.

Fix:
You can now modify the IPv6&IPv4 value within an existing data group.

Behavior Change:
users would be able to modify and update data groups

632668-6 : When a BIG-IP using BFD sessions is forced offline, the system continues to send "State Up" BFD packets for ~30 seconds

Component: TMOS

Symptoms:
When a BIG-IP using statically configured BFD sessions (i.e. "bfd session <IP> <IP>" in the ZebOS configuration) is forced offline, it continues to send "State Up" BFD packets for an additional ~30 seconds.

Conditions:
System is using statically configured BFD sessions. System is forced offline.

Impact:
The BFD peer thinks the BIG-IP is still online and may send packets to it.

Fix:
Ensure BFD "State Up" packets are not sent when the BIG-IP is forced offline.


632504-2 : APM Policy Sync: Non-LSO resources such as webtop are listed under dynamic resource list

Solution Article: K31277424

Component: Access Policy Manager

Symptoms:
Non-LSO resources such as webtop, even they are assigned via a normal resource assign agent, are listed under dynamic resource as opposed to static one.

Conditions:
- Create a webtop resource.
- Create an access profile.
- Launch VPE to assign webtop resource via a normal resource assign agent ("Advanced Resource Assign").
- Click on "Sync policy" button to bring up the policy sync dialog, click on "Advanced Settings" drop-down button and select "Static resources".

Impact:
No impact when default settings are configured for policy sync. Only in advanced setting is it confusing that a static resource is only listed in the dynamic resource list, with a prompt to include it as dynamic resource. Doing so does not cause any harm, but is unnecessary.

Workaround:
If it is a static resource, do not select it as dynamic resource.

Fix:
Static non-LSO resources such as webtop will be listed in static resource list in the advanced setting dialog for policy sync.


632499-2 : APM Policy Sync: Resources under webtop section are not sync'ed automatically

630712 : After provisioning change, Dimension Widgets on DoS Visibility pages are incorrect

Component: Application Visibility and Reporting

Symptoms:
Dimension Widgets list is defined upon first access to a DoS page during a browsing session. This means that if provisioning changes during that sessions, the widgets that are displayed may be incorrect.
When un-provisioning modules it is not a problem since every widget goes through a licensing/provisioning validation before being added to the page.
However, if adding a new module to provisioning, new widgets will not be added until the window/tab is closed and a new browsing session starts, or until "Reset Layout" is performed.

Conditions:
Change of provisioning modules during browsing session

Impact:
List of dimension widgets is not up to date with current provisioning

Workaround:
Workaround 1: closing and opening the window or tab.
Workaround 2: choosing "Reset Layout" option from the cog menu.

Your web application may have pages that do not handle the tags properly and may malfunction.

Workaround:
Configure injected tags in a way which can applied to all URLs protected in a profile. If it is not possible due to some URL HTML structure, HTML must be modified.

Fix:
Injected tags configuration has been moved to the URL level.


628164-4 : OSPF with multiple processes may incorrectly redistribute routes

Component: TMOS

Symptoms:
When OSPF is configured with multiple processes that each redistribute different type routes, LSAs may be created in a process for a route of the type other than the one configured for redistribution into that process.

Conditions:
OSPF routing with multiple processes configured. Each OSPF process configured with a different route type redistributed.

Impact:
Incorrect routing information in the network when OSPF converges.

Workaround:
Redistribute the leaked route type into the affected OSPF process and use a route map that filters out all routes.

Fix:
OSPF no longer leaks LSAs between processes redistributing different types of routes.

627695-1 : [netHSM SafeNet] The 'Yes' and 'No' options to proceed or cancel the unisntall during "safenet-sync.sh -u " are not operational

Component: Local Traffic Manager

Symptoms:
'Yes' and 'No' options to proceed or cancel the uninstall operation are not operational.

Conditions:
Issue happens when running safenet-sync.sh -u.

Impact:
No impact.

Workaround:
None.

Fix:
In this release, there is no Yes or No option for the SafeNet uninstall 'safenet-sync.sh -u.' command.


627554-1 : Partition of LTM policies is displayed in breadcrumb rather than properties table row

Component: TMOS

Symptoms:
There is no 'Partition/Path' row on LTM policies properties page. Instead the partition is displayed in the breadcrumb at the top of the page.

Conditions:
This is encountered when selecting a LTM policy.

Impact:
Partition/Path not displayed.

Workaround:
None.

Fix:
The partition was removed from the properties page breadcrumb and added as a 'Partition/Path' row to match the behavior of other LTM properties pages.


626861-1 : Ensure unique IKEv2 sequence numbers

Component: TMOS

Symptoms:
Although BIG-IP generates random sequence numbers for use in protocol negotiation, it is possible to allocate a new number already in use by a phase-one ike-SA or a phase-two child-SA.

Conditions:
When a sufficiently large number of tunnels are in use (e.g., numbering in thousands), odds of generating a duplicate sequence number is relatively high, given the number of random bits used to generate the number. More tunnels makes it more likely to occur.

Impact:
On sequence number collision, this might confuse an old SA, and probably never complete negotiation of a new SA. In addition, the system might crash if updating an old SA happened in a state where update is not expected.

Workaround:
None.

Fix:
Now BIG-IP uses more random bits in generated sequence numbers, and it always checks whether a new sequence number is currently in use anywhere else before proceeding. Thus collisions cannot be generated in sequence number allocation. New numbers should always be guaranteed unique now.


626594-3 : No way to perform a soft server certificate verification

Component: Local Traffic Manager

Symptoms:
There is no way to perform a soft server certificate verification.

Conditions:
Server-side SSL forward proxy when 'server certificate is set to 'require' and 'untrusted CA response control' and 'expired certificate response control' are both set to 'ignore'.

Impact:
No way to perform a soft server certificate verification and continue the handshake as though the verification is OK, even if it is not OK.

Workaround:
None.

Fix:
There is a new sys db variable: tmm.ssl.servercert_softval with default value 'disabled'.

When this sys db variable is 'enabled', calling SSL::verify_result will return a soft verfiy_result value.

Typical use case:
It is used in the server-side SSL forward proxy when 'server certificate is set to 'require' and 'untrusted CA response control' and 'expired certificate response control' are both set to 'ignore' but would like to perform a soft server certificate verification.

Behavior Change:
There is a new sys db variable: tmm.ssl.servercert_softval with default value 'disabled'.

When this sys db variable is 'enabled', calling SSL::verify_result will return a soft verfiy_result value.

Typical use case:
It is used in the server-side SSL forward proxy when 'server certificate is set to 'require' and 'untrusted CA response control' and 'expired certificate response control' are both set to 'ignore' but would like to perform a soft server certificate verification.


626386-2 : SSL may not be reassembling fragments correctly with a large-sized client certificate when SSL persistence is enabled

Component: Local Traffic Manager

Symptoms:
On a BIG-IP device, whenever a large-sized client certificate is sent by an SSL client to a virtual service, and SSL persistence is enabled, the SSID parser does not reassemble fragmented ClientKeyExchange messages correctly. It interprets the next incoming fragment - part of the CertificateVerify message - as a new record, incorrectly calculates its length and ends up waiting endlessly for more bytes to receive the record.

Conditions:
When SSL persistence is enabled and a large-sized client
certificate is sent by the SSL client to the BIG-IP device.

Impact:
Client connection hangs during the handshake. No impact to any other module.

Workaround:
Disable SSL persistence.

Fix:
SSL now reassembles fragments correctly with a large-sized client certificate when SSL persistence is enabled.


626311-1 : Potential failure of DHCP relay functionality credits to incorrect route lookup.

Component: Local Traffic Manager

Symptoms:
DHCP requests from client to server may not make it through.

Conditions:
-- BIG-IP system configured as a DHCP relay.
-- Input variable (flow_key) incorrectly initialized.

Impact:
Clients might not get an IP address from the DHCP server.

Workaround:
None.

Fix:
Input variable (flow_key) is initialized properly to prevent a potential route-lookup failure.


625892-1 : Nagle Algorithm Not Fully Enforced with TSO

Component: Local Traffic Manager

Symptoms:
Sub MSS packets are more numerous than Nagle's algorithm would imply.

Conditions:
TCP Segmentation Offload is enabled.

Impact:
Sub-MSS packets increase overhead and client power consumption.

Workaround:
Disable TCP Segmentation Offload by running the following command:
tmsh modify sys db tm.tcpsegmentationoffload value disable

Fix:
Deliver Integer Multiples of MSS to the TSO hardware when Nagle's algorithm applies.


624896-1 : GUI LTM Virtual Server Connection Limit and Connection Rate Limit

Component: TMOS

Symptoms:
Depending on the Virtual Server Type selection the Connection Limit and Connection Rate Limit may or may not be supported.

When changing the Virtual Server Type the GUI sometimes displays or hides the Connection Limit and/or Connection Rate Limit inconsistently.

Conditions:
When switching between Types, the Connection Limit and Connection Rate Limit may or may not be displayed or hidden correctly for the selected type.

Impact:
When updating the Virtual Server, if a value is persisted when it is not supported, the user will get an error. Or if a value is supported, but not visible, you cannot set the value through the GUI.

Workaround:
For values that are saved when they are not supported and the user gets an error, the user can set the value to 0. If the Connection Limit or Connection Rate Limit is not displayed in the GUI, the user can use tmsh to set the value.

Fix:
Ensure GUI is displaying and hiding Connection Limit and Connection Rate Limit correctly for each Virtual Server Type.

Component: Local Traffic Manager

Symptoms:
TCP Lossfilter function doesn't work properly, although the first few losses will be properly ignored.

Conditions:
TCP profile has ALL of the following settings:
mptcp disabled; rate-pace disabled; tail-loss-probe disabled; fast-open disabled; cmetrics-cache-timeout = 0; congestion ctrl is reno, new-reno, high-speed, or scalable; nagle enabled or disabled; rtx_thresh = 3; loss-filter settings are both > 0.

620659-4 : The BIG-IP system may unecessarily run provisioning on successive reboots

Component: TMOS

Symptoms:
After the first boot, the system runs provisioning and boots successfully, but there is a file left on the system /mprov_firstboot. This will appear in /var/log/ltm:
  info mprov:4614:: \'\'provision.initialized\' indicates force TMOS only provisioning - forcing.\'

During a subsequent boot, provisioning will run again, potentially unnecessarily, due to the existence of this file. The following will appear in /var/log/ltm during the second boot:
  info mprov:4609:: \'Existence of file \'/mprov_firstboot\' indicates force TMOS only provisioning - forcing.\'

Conditions:
The memory size of the host changes and there is some other need for reprovisioning (for example a new configuration load).

Impact:
On a vCMP host, the second provisioning may not complete properly and guest systems will not pass traffic.

The vCMP host will continually try to start more than one tmm and fail when there should only be one tmm running. The /var/log/tmm logfile on the vCMP host will contain:
  <13> Sep 25 01:33:28 vcmphost1 notice Too small memsize (60) -- need at least 136 MB

The /var/log/tmm logfile on the vCMP guest will contain:
  <13> Sep 25 01:38:21 bigip1 notice Failed to write /var/run/libdag.so_2, err: -30
  <13> Sep 25 01:38:21 bigip1 notice panic: vdag failed to attach
  <13> Sep 25 01:38:21 bigip1 notice ** SIGFPE **

Workaround:
If the vCMP host is in a tmm restart loop due to this issue, reboot the vCMP host to allow the system to come up properly.

Fix:
The BIG-IP software now always removes the /mprov_firstboot file when the system is reprovisioned.


620625-3 : Changes to the Connection.VlanKeyed DB key may not immediately apply

Component: Local Traffic Manager

Symptoms:
Changes to the Connection.VlanKeyed DB key may not immediately apply to all TMMs

Conditions:
The Connection.VlanKeyed DB key is changed

Impact:
Asymmetrically routed connections may fail with Connection.VlanKeyed disabled

Workaround:
Restarting TMM will resolve the issue, though this will interrupt traffic so should be performed during a maintenance window. To do so, run one of the following tmsh commands:

-- on an appliance (BIG-IP platform): bigstart restart tmm
-- on a clustered system (a VIPRION or VIPRION-based vCMP guest): clsh bigstart restart tmm

Fix:
Asymmetrically routed connections no longer fail with Connection.VlanKeyed disabled.

615372 : Occasional TCP resets during connection initiation (RST cause is "No local listener")

Component: TMOS

Symptoms:
Occasionally, the BIG-IP will send a TCP RST in response to an initial SYN with the reset cause "No local listener". This does not affect subsequent connections from the client, so they are likely to succeed.

The reset cause for a packet can be logged by setting the DB variable TM.rstcause.log to enable. The reset cause can be sent in the RST packet by setting the DB variable TM.rstcause.pkt to enable.

Conditions:
A virtual server is configured to use TCP and a client initiates a connection.

Impact:
The attempted connection is reset. Subsequent attempts are likely to succeed.

Workaround:
None.

Fix:
The icr_eventd daemon was updated to use TCP connections more efficiently.

Conditions:
Occurs once or twice per boot as a BIG-IP is being shut down or restarted.

Impact:
None. This can be ignored.

Workaround:
No workaround necessary. This message indicates no ill effects and can be ignored.

Fix:
This error message could have been generated once or twice at shutdown:

01070069:3: Subscription not found in mcpd for subscriber Id BIGD_Subscriber.

It no longer appears. Note that even when it was present, it only occurred at system shutdown and could be ignored.


610201-1 : Undefined behavior when calling HTTP::payload within HTTP_REQUEST_SEND iRule event

Component: Local Traffic Manager

Symptoms:
The invocation of HTTP::payload iRule API within the HTTP_REQUEST_SEND iRule event may lead to undefined behavior, such as retrieval of invalid HTTP data, or system crash.

Conditions:
The problem manifests itself exclusively with iRules attached to HTTP virtual servers, where the iRules are using the HTTP::payload API invocation within the HTTP_REQUEST_SEND server-side event.

Impact:
Corrupted HTTP data or system crash may result from the invocation of the HTTP::payload API within the HTTP_REQUEST_SEND iRule event.

Workaround:
The HTTP::payload API should not be invoked within the HTTP_REQUEST_SEND iRule event. According to the underlying API documentation, the valid HTTP events should be limited to CACHE_REQUEST, CACHE_RESPONSE, HTTP_REQUEST, HTTP_REQUEST_DATA, HTTP_RESPONSE, HTTP_RESPONSE_CONTINUE, HTTP_RESPONSE_DATA.

Fix:
The HTTP::payload API should not be invoked within the HTTP_REQUEST_SEND iRule event. According to the underlying API documentation, the valid HTTP events should be limited to CACHE_REQUEST, CACHE_RESPONSE, HTTP_REQUEST, HTTP_REQUEST_DATA, HTTP_RESPONSE, HTTP_RESPONSE_CONTINUE, HTTP_RESPONSE_DATA.

606710-11 : Mozilla NSS vulnerability CVE-2016-2834

Solution Article: K15479471


605792 : Installing a new version changes the ownership of administrative users' files

Component: TMOS

Symptoms:
Installing a new version changes the ownership of administrative users' files to a different, nonzero UID.

Conditions:
A user is an administrative user who has advanced shell (bash) access and custom files in their home directory.

Impact:
Low in most cases, since the administrative user can still access most files. One exception is that SSH requires that the authorized_keys file be owned by the user ID in question. This is 0 when a user has an administrative role, so the authorized_keys file will be ignored and a password will still be required for login.

Workaround:
Run the following command, substituting a different filename as needed: chown 0 /home/theuser/.ssh/authorized_keys.

Fix:
Installing a new version changes the ownership of administrative users' files to a different, nonzero UID. This still happens by design, but no longer applies to the user's SSH configuration files, which stay at UID 0. Therefore, these users are no longer be prevented from using stored public keys in authorized_keys.

Multiple Via headers on single-line separated by a single comma (',').

Impact:
Leading character of 2nd Via header will be stripped e.g. 'SIP/2.0/TCP' becomes 'IP/2.0/TCP'.

Workaround:
None.

Fix:
Removing the first Via header no longer strips the leading character from the second Via when headers are separated by a comma (',').


588414-1 : Displaying application components reports an error

Component: TMOS

Symptoms:
Displaying an iApp which contains an iRule from an iLX workspace reports an error.

Conditions:
Displaying an iApp which contains an iRule from an iLX workspace.

Impact:
The components page reports an error.

Workaround:
Use tmsh.

Fix:
Displaying application components no longer reports an error.


582773 : DNS server for child zone can continue to resolve domain names after revoked from parent

Component: Global Traffic Manager (DNS)

Symptoms:
See CVE-2012-1192. A domain name in a child server may continue to be resolved by the child server even after the parent server revokes the NS record for the child server.

Conditions:
A steady series of DNS queries for a domain name in the child. The TTL for the domain name A record is shorter than the TTL for the NS record for the child name server. The NS record is removed from the parent server.

Impact:
The revoked child server will still be used by a client after it is revoked.

Workaround:
Restart the TMM to clear out the cache.

Fix:
Do not update the NS record TTL to the value returned from the child server.


581746-6 : MPTCP or SSL traffic handling may cause a BIG-IP outage

Solution Article: K42175594

Component: Local Traffic Manager

Symptoms:
Occasional BIG-IP outages may occur when MPTCP or SSL traffic is being handled by a virtual server.

Conditions:
MPTCP has been enabled on a TCP profile on a virtual server, or SSL is in use.

Impact:
A system outage may occur.

Workaround:
None.

Fix:
An issue with handling of MPTCP and SSL traffic has been corrected.


578076 : OpenSSL vulnerability CVE-2016-0800

578017 : CVE-2016-0800 : SSLV2 "DROWN" Vulnerability

Solution Article: K23196136


575642 : rst_cause of "Internal error"

Component: Local Traffic Manager

Symptoms:
The rst_cause may be logged as "Internal Error". rst_cause of "Internal error" does not give a narrow reason for the reset. It means that one of the other reset causes was not matched but the exact issue cannot be determined from this generic error.

Conditions:
Heavy/normal production network usage.

Impact:
System problem diagnosis is more difficult.

Workaround:
N/A


572272 : BIG-IP - Anonymous Certificate ID Enumeration

Component: TMOS

Symptoms:
Requests to the BIGIP mgmt API verify parameters separately and can return responses that indicate which parameter was invalid.

Conditions:
--

Impact:
Possible disclosure of the em_server_ip field of valid client certificates. This does not reveal the certificate needed for authentication.

Workaround:
--

Fix:
When these parameters are invalid the external response no longer indicates the specific reason. The reason is still logged in the apache logs for administrator review.

Behavior Change:
Whenever a communication starts between BIG-IQ and BIG-IP, there are two certificates being exchanged to avoid using the credentials on every request. Once they are shared, BIG-IQ stops using the BASIC authorization and switches to an authorization relying in two parameters that are sent in the URL: em_server_ip and em_server_auth_token.

When these parameters are invalid for some reason, the 401 response no longer indicates the reason. The reason is still logged in the apache logs.


572234-1 : When using a pool route, it is possible for TCP connections to emit packets onto the network that have a source MAC address of 00:98:76:54:32:10.

Component: Local Traffic Manager

Symptoms:
When using a pool route, it is possible for TCP connections to emit packets onto the network that have a source MAC address of 00:98:76:54:32:10. This is the MAC address of Linux's tmm0 or tmm interface.

Conditions:
The traffic destination is the BIG-IP Linux host, e.g. big3d iQuery server.

The traffic is proxied via fastL4, e.g. ConfigSync "Local Address" is set to None.

The return route is a pool route.

The traffic is interrupted, e.g. a router between the iQuery server and the client is switched off for several seconds.

Impact:
The traffic is sourced from invalid ethernet MAC 00:98:76:54:32:10.
The iQuery connection cannot continue.

Workaround:
Increase the lasthop module's TCP idle timeout.

echo 121 > /proc/sys/net/lasthop/idle_timeout/tcp

Fix:
TCP connections no longer emit packets that have a source MAC address of 00:98:76:54:32:10.


570926 : Provide a way to configure where in payload the CSPM JS is injected.

Component: Application Visibility and Reporting

Symptoms:
This is an enhancement that allows you to choose where in the document the CSPM script will be injected.

Conditions:
You are using some application that can't read the document if something appears after closing the html tag.

Impact:
Today we append the CSPM payload (for client latency measurements) at the end of the HTML document (after the html tag).
This works in browsers but it's not compliant to the HTML standard and may break some applications that rely on this standard (not browsers).

Workaround:
Un-checking "Page Load Time" in analytics profile.

Fix:
Verify that script was injected to the chosen location in the returned document.


570855-1 : DB variable log.csyncd.level cannot be set to certain values

Component: Local Traffic Manager

Symptoms:
The DB variable log.csyncd.level lists some values for tab completion, but validation prevents you from setting them. The error message looks like this:

01070911:3: The requested enumerated (alert) is invalid (critical, error, warning, notice, informational, debug) for loglevel in daemon_csyncd (/Common/daemon_csyncd)

Conditions:
You are trying to use the DB variable log.csyncd.level to increase the amount of information logged by csyncd. csyncd is a system service that on chassis mirrors certain portions of the filesystem between blades, and on all BIG-IP devices runs certain commands after detecting filesystem changes.

Impact:
You cannot set the log level to certain values.

Workaround:
If you want more debugging information, set the log level to 'debug', which is still accepted.

Fix:
The DB variable log.csyncd.level lists some values for tab completion, but validation formerly prevented you from setting them. This has now been resolved; all advertised values will now be accepted.


569814 : iRule "nexthop IP_ADDR" rejected by validator

Component: Local Traffic Manager

Symptoms:
The nexthop command allows an administrator the ability to specify a forwarding address in an iRule. The form which takes an IP address may be rejected by the validator with an error message of the form:

01070151:3: Rule [/Common/irule_example] error: Unable to find vlan, vlangroup or tunnel (10.0.0.1) referenced at line 2: [nexthop 10.0.0.1]

Conditions:
This occurs when the nexthop command contains only the IP address, for example:

when HTTP_REQUEST {
  nexthop 10.0.0.1
}

Impact:
The iRule containing the 'nexthop IP_ADDR' command cannot be associated with a virtual server.

Workaround:
The 'nexthop VLAN IP_ADDR' form of the command does pass the validator. Choose the named vlan on which IP_ADDR can be reached. For example:

    when HTTP_REQUEST {
nexthop internal 10.0.0.1
    }

Fix:
Validator now allows 'nexthop IP_ADDR' in iRules.


569100 : Virtual server using NTLM profile results in benign Tcl error

Solution Article: K57982555

Component: TMOS

Symptoms:
Tcl error in /var/log/ltm.

Tcl error: bad option "serverside": must be require or preclude while executing "constrain NTLM require clientside {HTTP} serverside {CONNPOOL} preclude FTP

Conditions:
Virtual server using the NTLM profile. Only logged when the first virtual server is created or when TMM restarts.

Impact:
If you are using TMSH to configure virtual server and NTLM profile, validation/constraint is not performed/enforced.

Workaround:
This is a benign, cosmetic error. There should be no functional impact to the system.

Fix:
Fixed the unexpected error message encountered and added validation when creating a virtual server with an NTLM profile.


563165 : New Diameter session event triggers registered for by the PCRF should not be appended to existing registered event triggers in PEM.

Component: Policy Enforcement Manager

Symptoms:
PCRF may receive old event triggers it is not interested in.

Conditions:
PEM with a valid Gx interface should receive more than one set of event triggers that the PCRF needs to register for.

Impact:
Increase in Diameter traffic.

Fix:
Discard previously registered event triggers while registering a new set.


561596 : Hotfixes can optionally update FPS engine file

Component: TMOS

Symptoms:
Previously, to receive a full solution that required changes on the FPS BIG-IP side and FPS client-side, both a hotfix and a live update were required.

Conditions:
FPS hotfix

Impact:
No ability to opt in/out of engine and signature changes from the hotfix

Workaround:
N/A

Fix:
Two new DB variables to enable/disabled taking update from hotfix:

datasync.update_engine_from_factory
datasync.update_signatures_from_factory


561592 : Hotfixes can update FPS engine file

Component: TMOS

Symptoms:
Previously, to receive a full solution that required changes on the FPS BIG-IP side and FPS client-side, both a hotfix and a live update were required.

Conditions:
FPS hotfix

Impact:
You have to install both the hotfix and the engine update

Workaround:
Install live update separately

Fix:
Hotfix can now update the FPS javascript engine


559080 : High Speed Logging to specific destinations stops from individual TMMs

Component: TMOS

Symptoms:
High Speed Logging to specific destinations stops from individual TMMs. The flows appear to have very large idle times. Attempts to delete the flows sets the idle time to zero, but does not kill the flow.

Conditions:
This appears to be the result of a failure on the part of the log destination (for example, a log server) wherein the server's TCP stack ACKs a FIN request from the TMM, but does not follow through with a matching FIN or RST. The logging code expects another timeout (essentially a FIN-WAIT2 timeout), but never receives one because the flow has already been marked as expired. As a result, the flow goes into a state in which it appears to be viable but is not actually delivering.

Impact:
Logs are silently lost.

Workaround:
Create an additional virtual server to act as a proxy for the log server, and sent the logs to this virtual server. This essentially uses the TMM itself as a sanitizing proxy.

Fix:
The system now resets the expire timer when it initiates the close. If the server fails to reset or complete the close, the flow is aborted on the next expiration event.


552988-1 : Cannot enable MPTCP on some profiles in GUI.

Component: Local Traffic Manager

Symptoms:
Version 12.1 Cannot enable MPTCP on some profiles in GUI. Get error message: 01070734:3: Configuration error: In profile /Common/proxy-client to enable MPTCP, Hardware SYN Cookie must be disabled.

Conditions:
Version 12.1 Enabling MPTCP on some profiles in GUI.

Impact:
Version 12.1 Cannot enable MPTCP.

Workaround:
Use tmsh to enable MPTCP on some profiles.

Fix:
Eliminate validation: it is reasonable to have MPTCP function until entering syncookie mode.


550547-1 : URL including a "token" query fails results in a connection reset

Component: Access Policy Manager

Symptoms:
Per Request Policy access to URL containing a "token" query parameter fails and results in a connection reset with the following error:

"ERR_NOT_FOUND: access2 token not found; subsession might be inactive"

Conditions:
Configure an Explicit SWG with a PRP that includes [protocol lookup (https) + category-lookup]
It does not matter ntlm or basic auth.
This is triggered on sites that have "token" in the query parameters.

Impact:
Clients receive this response:
"ERR_NOT_FOUND: access2 token not found; subsession might be inactive"

Workaround:
Workaround iRule:

when HTTP_REQUEST {
    if { [HTTP::query] contains "token" } {
      set fix 1
      HTTP::query [string map "token aabbcc" [HTTP::query]]
    }
}

when HTTP_REQUEST_SEND {
    if { [info exists fix] && $fix equals 1 } {
      clientside {
        HTTP::query [string map "aabbcc token" [HTTP::query]]
        unset fix
      }
    }
}

Fix:
Customization namespace for subsession state prefix with default value as "000fffff" has been added controlled via db variable "tmm.access.subsessionstateprefix" before state/token query param and validation is ensured to check for the prefix value before triggering serialize/deserialize code to avoid RST.

In case if a UCS is being restored and used for a Hotfix, the newly added DB variable may not be present in /config/Bigdb.dat file. The following information needs to be added in /config/Bigdb.dat file followed by a "bigstart restart" to ensure proper working.

#
# This string is used as the prefix for the subsession state value that is sent as
# part of the redirect URI being sent to the client.
#
[Tmm.Access.SubsessionStatePrefix]
default=000fffff
type=string
realm=local
display_name=Tmm.Access.SubsessionStatePrefix
scf_config=true
max=32


541550-2 : Defining more than 10 remote-role groups can result in authentication failure

Component: TMOS

Symptoms:
Authentication fails, indicating the affected user is associated with an "unknown" role:

notice httpd[2112]: pam_bigip_authz: authenticated user bob with role 12345678 ([unknown]) in partition /bin/false

Conditions:
Define more than 10 remote-role groups and authenticate with a user having more than 10 roles.

Impact:
User cannot authenticate.

Workaround:
None.


541320-8 : Sync of tunnels might cause restore of deleted tunnels.

Solution Article: K50973424

Component: TMOS

Symptoms:
After a full load sync, tunnels may be spuriously added to the default route domain for the partition that contains them.

Conditions:
Viewing tunnels after a full load sync.

Impact:
This might result in a deleted tunnel being restored to the configuration.

Workaround:
None.

Fix:
Sync of tunnels no longer causes restore of deleted tunnels.


517756-5 : Existing connections can choose incorrect route when crossing non-strict route-domains

Component: Local Traffic Manager

Symptoms:
After modifying the BIG-IP system's routing table, traffic for some existing connections might be interrupted because an incorrect route starts being used.

Conditions:
After a routing table modification, routes might be reselected for a portion of connections through the BIG-IP system. When a connection crosses non-strict route-domains, the routing table from a route-domain that is different from the route-domain used during connection start-up may be used.

Impact:
This might lead to traffic following a different path to the destination and traffic interruption. New connections will work properly, this only affects existing connections.

Workaround:
None.

Fix:
Existing connections now choose the correct route when crossing non-strict route-domains.


508113-2 : tmsh load sys config base merge file <filename> fails

Component: TMOS

Symptoms:
Save sys config file.

(tmos)# save sys config file demo.scf no-passphrase
Saving running configuration...
  /var/local/scf/demo.scf
  /var/local/scf/demo.scf.tar

Try to load the base configuration within this file.

(tmos)# load sys config base merge file demo.scf
Loading configuration...
  /var/local/scf/demo.scf
Syntax Error:(/var/local/scf/demo.scf at line: 6) "apm" unexpected argument

The error is from a system configuration, not user created.

apm report default-report {
    report-name sessionReports/sessionSummary
    user /Common/admin
}

Basically the configuration fails to load all components for unprovisioned modules and features.

Conditions:
Running the command: load sys config base merge file <filename> when the system contains unprovisioned modules and features.

Impact:
tmsh load sys config base merge file <filename> fails.

Workaround:
None.

Fix:
The provisioning checks were modified to let this command succeed.


489499-2 : chmand needs to check for LopUnsSensClientExists status after registering for unsolicited alerts with lopd

Component: TMOS

Symptoms:
chmand fails to register for unsolicited LOP events, meaning that asynchronous alerts from lopd will not seen or reported by chmand. A message is seen in /var/log/ltm that contains the phrase, "failed to register for LOP at <address>"

Conditions:
Occurs when chmand has been re-started after it has already synchronized once with lopd.

Impact:
Asynchronous events from lopd will not be reported or handled, such as fan tray removal/insertion and PSU removal/insertion. Alerts that are driven by system_check through polling sensor values and comparing them to specified limits, however, will still be operational.

Workaround:
Re-start lopd:
# bigstart restart lopd

Fix:
Modified chmand to recognize the case where unsolicited alert registration with lopd has already occurred so that it no longer treats it as an error.


429213 : Some monitor types assigned to the same node IP:port in different Route Domains may collide and mark the object down.

Component: Local Traffic Manager

Symptoms:
A race condition may occur in which a monitor instance is killed abruptly if another copy of the same monitor attempts to check health of the same node IP:port in a different route domain. The killed monitor will then contribute to a monitoring timeout and potentially mark the node as down.

This issue occurs because the PID file created to prevent duplicate monitoring of the same pool member is not sufficiently unique to distinguish between route domains. For example, SIP monitor named "sip_london" applied to pool members 1.2.3.4%100 and 1.2.3.4%200 would share the same PID file:

/var/run/SIP__Common_sip_london.::ffff:1.2.3.40..5060.pid

Conditions:
For health monitor types which execute outside of the bigd process (see list below), a health monitor profile is assigned to monitor 2 different nodes which have the same IP:port in different route domains.

The affected monitor types include:

Diameter
IMAP
LDAP
NNTP
POP3
Radius
Radius Accounting
RPC
Scripted
SIP
SMB
SMTP
WAP

Impact:
Pool members may flap down/up.

Workaround:
To work around this, perform the following steps:

1. Create a duplicate copy of the monitor profile, and add the route domain to the name of the monitor profile. For example:

ltm monitor radius /Common/radius_seattle_rd43 {
    default-from /Common/radius_seattle
}

2. For nodes or pool members in that route domain, replace the old monitor profile with the new duplicate monitor profile.


419741-4 : Rare crash with vip-targeting-vip and stale connections on VIPRION platforms

Component: Local Traffic Manager

Symptoms:
Rare TMM crash bug with vip-targeting-vip. Core analysis is typically necessary to determine whether this bug is the cause.

Conditions:
Triggering this bug is difficult and seems to require vip-targeting-vip (e.g., use of the 'virtual' command in an iRule) and more than one blade.

Impact:
In rare situations, the TMM crashes.

Workaround:
None. This occurs rarely, and the system recovers automatically. Although this workaround has not be verified, in situations where virtual A targets virtual B via the 'virtual' command, it should be sufficient for virtual A to have shorter timeouts than virtual B.


417720 : BIG-IP LTM Log Indicates Chassis Power Turned Off During Fan Speed Failures

Component: TMOS

Symptoms:
If a power supply fan unit becomes jammed or experiences a failure that prohibits the minimum RPM threshold to be met, the LTM log will erroneously indicate that the power supply has been turned off. For example:

localhost crit chmand[8482]: 012a0013:2: Blade 0 hardware sensor critical alarm: Power Supply 2 GPIO status(73-610-125): Bad

localhost crit chmand[8482]: 012a0013:2: Blade 0 hardware sensor critical alarm: Power supply #2 fan-1: Bad

localhost warning chmand[8482]: 012a0018:4: Chassis power module 2 turned off.

Conditions:
Any kind of power supply fan failure that prevents the unit from achieving the minimum spec. for RPMs.

Impact:
Misleading log message.

Workaround:
None.


367226-3 : Outgoing RIP advertisements may have incorrect source port

Component: Local Traffic Manager

Symptoms:
TMM may change the source port of RIP packets send by ripd to something other than 520. Neighbor routers will not accept these packets and RIP routing will not work.

If the TMM instance handling the outgoing packet would not be selected to handle return traffic by the hashing algorithm in use, the source port of the traffic will be modified so the hashing algorithm returns the same TMM instance.

Conditions:
Multiple TMM instances, RIP routing configured.

Impact:
Dynamic routing using RIP will not work if the traffic hash of the packets does not match the TMM handling the outgoing traffic.

Fix:
TMM no longer modifies the source port of RIP traffic.


366695-9 : Remove managers create/modify/delete ability from TMSH on GTM datacenters, links, servers, prober-pools, and topology errors incorrectly, and receive a database error when performed

Component: Global Traffic Manager (DNS)

Symptoms:
A "Manager" role has the ability to create/modify/delete GTM data centers, links, servers, prober pools, and topology objects from TMSH, but they do not have this permission in the database, so they get an error.

Conditions:
Someone of "Manager" roll attempts to create/modify/delete a GTM datacenter, link, server, prober-pools, or topology objects.

Impact:
Error message thrown

Workaround:
Error thrown is correct, but user's shouldn't be able to even get this far in tmsh.

Fix:
Removed Manager's ability to create/modify/delete GTM data centers, links, servers, prober-pools, and topology objects. This was already prevented through validation code, but now TMSH users only have access to view these objects.


352957-2 : Route lookup after change in route table on established flow ignores pool members

Component: Local Traffic Manager

Symptoms:
Established flows via Virtual Servers with iRules using the 'nexthop vlan addr' command to set the nexthop to a different address than the gateway returned in route lookup, or transparent flows to a pool member, might fail after a route table change, even if the change does not affect any of the addresses used in the flow.

Conditions:
An iRule with 'nexthop vlan addr' on the CLIENT_ACCEPTED state is added to a virtual server with pool members and the address in the nexthop command is different from the gateway.

Impact:
A flow established before a route table change may fail if the destination was set in an iRule using 'nexthop'. New flows established after the route table change work as expected.

Workaround:
Modify iRule to fire 'nexthop' on every client packet. If the flow has been modified due to a route change, then the next client packet that fires 'nexthop' will correct it.

Fix:
The nexthop for established flows, set using "nexthop vlan addr" in an iRule for CLIENT_ACCEPTED state, does not change when there are changes in the route table. This is correct behavior.


247527-1 : Mgmt interface cannot be disabled via tmsh

Solution Article: K14890

Component: TMOS

Symptoms:
Issuing a tmsh command to disable the management interface of a blade or appliance appears to succeed, but the management interface is not actually disabled.

Conditions:
This problem occurs on the following hardware platforms:
BIG-IP 1500, 3400, 3410, 6400, 6800, 8400, and 8800 appliances.

This problem does not occur on the following hardware platforms:
BIG-IP 1600, 3600, 3900, 6900, 8900-series and 11000-series appliances.

Impact:
After using the tmsh utility to set the mgmt interface to a disabled state, the tmsh utility will show the mgmt interface as disabled. However, the mgmt interface still responds to network traffic, including ping and ssh.

Workaround:
There are three possible ways to work around this issue:

1) Unplug the management interface if it is not intended to be used.

2) Bring down the switch interface to which the management port connects.

3) Disable the management interface using the following information below.

Important: This workaround might cause unintended consequences. Only use this option as a last resort, as disabling the management interface may remove the ability for the Linux host to communicate with several of the BIG-IP subsystems. As a result of this loss of communication, certain BIG-IP features may not function as expected or at all.

For platforms that expose a 'mgmt' interface via ifconfig, run the command: ifconfig mgmt down. To bring the 'mgmt' interface back up, run the command ifconfig mgmt up.

For platforms that do not expose a 'mgmt' interface via ifconfig, run the command: ifconfig eth0 down. To bring 'eth0' interface back up, run the command ifconfig eth0 up.

Component: Local Traffic Manager

Symptoms:
clusterd logs heartbeat check messages at log level info

Conditions:
log.clusterd.level set to info

Impact:
cosmetic: clusterd heartbeat messages will be logged at info to the /var//log/ltm

Workaround:
set log.clusterd.level to notice


694656-2 : Routing changes may cause TMM to restart

Component: Local Traffic Manager

Symptoms:
When routing changes are made while traffic is passing through the BIG-IP system, TMM might restart. This isn't a general issue, but can occur when other functionality is in use (such as Firewall NAT).

Conditions:
-- Routing changes occurring while BIG-IP is active and passing traffic.

-- Dynamic routing, due to its nature, is likely increase the potential for the issue to occur.

-- Usage of Firewall NAT functionality is one specific case known to contribute to the issue (there may be others).

Impact:
TMM restarts, resulting in a failover and/or traffic outage.

Workaround:
If dynamic routing is not in use, avoiding static route changes may avoid the issue.

If dynamic routing is in use, there is no workaround.


694624-2 : SSO enabled Native RDP resources can't be accessed via hardware BIG-IP with "Intel Cave Creek" coprocessor

Component: Access Policy Manager

Symptoms:
APM Webtop's SSO enabled Native RDP resources can't be accessed via hardware BIG-IP with "Intel Cave Creek" coprocessor (e.g. BIG-IP 2000 (C112) or 4000 (C113)) from Mac, iOS and Android clients. Each launch attempt generates following errors in /var/log/apm:
... err vdi[123] ... {45.C} RsaDecryptData error: AsyncError:5: InvalidData
... err vdi[123] ... {45.C} An exception is thrown: handshake: decryption failed or bad record mac

Conditions:

The client OS is Mac, iOS or Android.

Impact:
RDP client can't launch requested resource (desktop/application).

Workaround:
Disable crypto HW acceleration with following command:
tmsh modify sys db crypto.hwacceleration value disable


694491 : Errant log message appears as an error

Component: Local Traffic Manager

Symptoms:
A log message similar to the following appears in /var/log/ltm:

err mcpd[]: 0107167d:3: Data publisher not found or not implemented when processing request (unknown request), tag (31624).

Conditions:
No specific conditions trigger this message. You might see this message when you inspect the LTM log after booting.

Impact:
There is no negative impact to the system. You can safely ignore this message.

Workaround:
No need for a workaround. The message can be ignored or filtered.


694490 : vCloud Director images not available

Component: TMOS

Symptoms:
There is no dedicated vCloud Director BIG-IP image of v13.0.0 HF3 to use for install/upgrade operations.

Conditions:
-- Installing BIG-IP v13.0.0 HF3.
-- Upgrading to BIG-IP v13.0.0 HF3 from a prior release.

Impact:
Cannot use previously available method of installing/upgrading using a dedicated vCloud Director image.

Note: Separate vCloud Director images are not available for BIG-IP v13.0.0 HF3. However, you can upgrade using the hotfix ISO or install using the general OVA images.

Workaround:
Upgrade a prior release using the hotfix ISO, or install using OVA for other VMware environments.


693996-4 : MCPD sync errors and restart after multiple modifications to file object in chassis

Component: TMOS

Symptoms:
Upon modifying file objects on a VIPRION chassis and synchronizing those changes to another VIPRION chassis in a device sync group, the following symptoms may occur:

1. Errors are logged to /var/log/ltm similar to the following:

-- err mcpd[<#>]: 0107134b:3: (rsync: link_stat "/config/filestore/.snapshots_d/<_additional_path_to/_affected_file_object_>" (in csync) failed: No such file or directory (2) ) errno(0) errstr().
-- err mcpd[<#>]: 0107134b:3: (rsync error: some files could not be transferred (code 23) at main.c(1298) [receiver=2.6.8] syncer /usr/bin/rsync failed! (5888) () Couldn't rsync files for mcpd. ) errno(0) errstr().
-- err mcpd[<#>]: 0107134b:3: (rsync process failed.) errno(255) errstr().
-- err mcpd[<#>]: 01070712:3: Caught configuration exception (0), Failed to sync files..

2. MCPD may restart on a secondary blade in a VIPRION chassis that is receiving the configuration sync from the chassis where the file object changes were made.

Conditions:
Making multiple changes to the same file objects on a VIPRION chassis and synchronizing those changes to another VIPRION chassis in a device sync group.

Impact:
Temporary loss of functionality, including interruption in traffic, on one or more secondary blades in one or more VIPRION chassis that are receiving the configuration sync.

Workaround:
After performing one set of file-object modifications and synchronizing those changes to the high availability (HA) group members, wait for one or more minutes to allow all changes to be synchronized to all blades in all member chassis before making and synchronizing changes to the same file-objects.


693910-3 : Traffic Interruption for MAC Addresses Learned on Interfaces that Enter Blocked STP State (2000/4000/i2800/i4800 series)

Component: Local Traffic Manager

Symptoms:
Some MAC addresses might experience delayed forwarding after the interface on which they are learned transition to a STP blocked state. This is because the FDB entries are not being flushed on these interfaces after they change to a block state. Traffic destined to these MAC addresses gets dropped until their associated entries in the FDB age out.

Conditions:
MAC addresses are learned on a STP forwarding interface that transitions to a blocked interface following a topology change.

Impact:
Traffic interruption for up to a few minutes for MAC addresses learned on the affected interface.

Workaround:
None.


693563-2 : No warning when LDAP is configured with SSL but with a client certificate with no matching key

Component: TMOS

Symptoms:
When LDAP auth is configured with SSL:

- Authentication attempts fail
- Packet captures between the BIG-IP system and the LDAP server show the BIG-IP system sending FIN after TCP handshake.

Conditions:
LDAP auth is configured with SSL with client cert set but no matching key.

Impact:
LDAP auth fails. There is no warning that the auth failed.

Workaround:
Configure a key that matches the specified client certificate.


693244-1 : BIG-IP not sending RST for SYN,ACK packets when ASM is provisioned

Component: Local Traffic Manager

Symptoms:
BIG-IP silently drop the serverside TCP flow, when it receives a client-side reset and the server-side flow is still in the SYN-SENT state.

Conditions:
BIG-IP receives a client-side reset when client-side TCP flow is in ESTABLISHED state and server-side TCP flow is in SYN-SENT state, serverside flow is silently dropped.

Impact:
Since serverside pool member does not receive the RST, it remains in SYN-RECEIVED state until it runs out of syn retransmissions and eventually, due to timeout, it returns to LISTEN state.


693007-2 : Modify b.root-servers.net IPv4 address 192.228.79.201 to 199.9.14.201 according to InterNIC

Component: Global Traffic Manager

Symptoms:
The current IPv4 address for b.root-servers.net is 192.228.79.201. The IPv4 address for b.root-servers.net will be renumbered to 199.9.14.201, effective 2017-10-24. The older number will be invalid after that date.

Conditions:
Several profiles contain the b.root-servers.net IPv4 address as 192.228.79.201.

Impact:
The impact is likely minimal, at most a single timeout for pending TLD queries when they happen to round-robin onto an old IP address, probably not more often than the hint's TTL, which is more than a month, and even this should cause a timeout only when the old IP actually stops responding.

Workaround:
Update the root hints for all affected profiles manually except the hardwired ones.


692970-1 : Using UDP port 67 for other purpose than DHCP could cause TMM to crash

Component: Local Traffic Manager

Symptoms:
DHCP relay presumes that a flow found via lookup is always a server side flow of type DHCP relay. Hence TMM can crash when DHCP relay makes a server connection if UDP port 67 is used for other purpose, in which case a wrong DHCP server flow could be selected.

Conditions:
A UDP port 67 is configured for other purpose than DHCP relay.

Impact:
TMM crash causes traffic interruption or failover.

Workaround:
Do not use UDP port 67 for other VIPs, or configure a drop listener on certain VLAN(s) that can't avoid using UDP port 67.


692941-2 : GTMD and TMM SIGSEGV when changing wide IP pool in GTMD

Component: Global Traffic Manager (DNS)

Symptoms:
Changing wide IP causes gtmd and tmm core under certain conditions.

Conditions:
-- GTM pool is removed when it is referenced by a persist record.
-- That record is accessed before it is purged.

Impact:
gtmd and tmm core. Traffic disrupted while tmm restarts.

Workaround:
None.


692778-2 : Persist record remains even when the pool is removed from the wide IP.

Component: Global Traffic Manager (DNS)

Symptoms:
Persist record remains even when the pool is removed from the wide IP.

Conditions:
Remove the pool from a wide IP which already has a persist record to that pool.

Impact:
GTM returns DNS request to a pool which is not associated with the Wide IP.

Workaround:
None.


692557-2 : When BIG-IP as SAML IdP processes signed authentication requests from external SAML SP, a block of memory may become corrupted.

Component: Access Policy Manager

Symptoms:
After processing signed authentication requests from external SAML SP, SAML IdP may corrupt a block of tmm memory.

Conditions:
- BIG-IP system is configured as SAML IdP.
- IdP is configured with external SP's signing certificate.
- External SP sends signed authentication request.

Impact:
Various possible negative effects, including TMM core. Traffic disrupted while tmm restarts.

Workaround:
None.


692189-2 : errdefsd fails to generate a core file on request.

Component: TMOS

Symptoms:
Should errdefsd crash or be manually cored for the purpose of gathering diagnostic information, no core file will be generated.

Conditions:
Forcing errdefsd to core for diagnostic purposes.

Impact:
Increased communication required with F5 Support when attempting to diagnose problems with errdefsd.

Workaround:
1. Add the following lines to the official errdefsd script, /etc/bigstart/scripts/errdefsd:
16a17,19
> # set resource limits, affinity, etc
> setproperties ${service}
>
2. Run the following command: bigstart restart errdefsd


692183-2 : Deprecated DB variables

Component: TMOS

Symptoms:
The following DB variables have been deprecated and no longer have any effect:

connection.syncookies.threshold
pvasyncookies.virtual.connthresholdhigh
pvasyncookies.virtual.invalidthreshold
pvasyncookies.virtual.maxsyncache

Conditions:
Once running, these values have no effect at all.

Impact:
pvasyncookies.virtual.invalidthreshold is now ignored.

connection.syncookies.threshold, pvasyncookies.virtual.connthresholdhigh, and pvasyncookies.virtual.maxsyncache are used on upgrades from older releases to determine the initial value of the setting located at "ltm global-settings connection syncookies-threshold". After upgrade is complete, they are also ignored.

Workaround:
No action is necessary.


692179-2 : Potential high memory usage from errdefsd.

Component: TMOS

Symptoms:
errdefsd memory usage grows with each config-sync or config update.

Conditions:
Ever increasing errdefsd memory usage is visible when the following conditions are met:
-- Config updates are frequent.
-- management-port logging is not being used.

Impact:
In extreme cases, errdefsd memory usage might increase userland memory-pressure. Note, however, that it isn't actually using the extra memory, so while Virtual Memory Size (VSZ) might be high, Resident Set Size (RSS) need not be.

Workaround:
A workaround for this problem is to periodically send logs to a management-port destination. The destination may be as simple as a dummy UDP port on 127.0.0.1. Adding such a destination to the publisher for an existing, active log source will work. errdefsd just needs a reason to process and flush accumulating configurations.


692123-1 : GET parameter is grayed out if MobileSafe is not licensed

Component: Fraud Protection Services

Symptoms:
GET parameter is grayed out if MobileSafe is not licensed.

Conditions:
-- Provision FPS on a system whose license has at least one active feature.
-- Do not license MobileSafe.

Impact:
In FPS Parameter's list, the GET method is always grayed out.

Workaround:
Use either of the following workarounds:
-- License MobileSafe.
-- Use TMSH or REST.


692095-2 : bigd logs monitor status unknown for FQDN Node/Pool Member

Component: Local Traffic Manager

Symptoms:
While monitoring FQDN nodes or pool members, bigd may log the current or previous monitor status of the node or pool member as 'unknown' in messages where that state internally could have been logged as 'checking' or 'no address' for FQDN template nodes. Other states for FQDN configured nodes or pool members log monitor status as expected. Messages are similar to the following:

notice bigd[####]: 01060141:5: Node /Common/node_name monitor status unknown [ ip.address: unknown ] [ was up for ##hrs:##mins:##sec ]
notice bigd[####]: 01060141:5: Node /Common/node_name monitor status up [ ip.address: unknown ] [ was unknown for ##hrs:##mins:##sec ]
notice bigd[####]: 01060141:5: Node /Common/node_name monitor status up [ ip.address: up ] [ was unknown for ##hrs:##mins:##sec ]
notice bigd[####]: 01060145:5: Pool /Common/pool_name member /Common/node_name monitor status unknown. [ ] [ was unchecked for ##hrs:##mins:##sec ]
notice bigd[####]: 01060145:5: Pool /Common/pool_name member /Common/node_name monitor status up. [ ] [ was unknown for ##hrs:##mins:##sec ]

Conditions:
This may occur of the FQDN template node or pool member is in a 'checking' or 'no address' state.
The 'checking' state may occur if the DNS resolution of the FQDN node or pool member name is in progress.
The 'no address' state may occur if no IP addresses were returned by the DNS server for the configured FQDN node or pool member name.

Impact:
Unable to triage state of FQDN nodes or pool members identified in these log messages, to determine whether further troubleshooting is required, or what specific problem condition might require further investigation.

Workaround:
None.


691806-2 : RFC 793 - behavior receiving FIN/ACK in SYN-RECEIVED state

Component: Local Traffic Manager

Symptoms:
The BIG-IP system resets connection with RST if it receives FIN/ACK in SYN-RECEIVED state.

Conditions:
The BIG-IP system receives FIN/ACK when it is in SYN-RECEIVED state.

Impact:
The BIG-IP system resets connection with RST.

Workaround:
None.


691785-2 : The bcm570x driver can cause TMM to core when transmitting packets larger than 6144 bytes

Component: Local Traffic Manager

Symptoms:
The bcm570x driver will cause TMM to core with the log message:

panic: ifoutput: packet_data_compact failed to reduce pkt size below 4.

Conditions:
-- Running on a platform that uses the bcm570x driver (BIG-IP 800, 1600, 3600).
-- A packet larger than 6144 bytes is transmitted from the BIG-IP system.

Impact:
TMM core. Failover or outage. Traffic disrupted while tmm restarts.

Workaround:
None.


691749-2 : reset-stats operations cannot be part of TMSH transactions

Component: TMOS

Symptoms:
Operations that reset statistics are currently cannot be part of transactions. A know exception to this is the "delete sys connection ..." command. Once the TMSH transaction is submitted, TMSH actually freezes up if a "delete sys connection ..." command was included.

Conditions:
include reset-stats operations in the TMSH transactions

Impact:
reset-stats operations cannot be part of TMSH transactions

Workaround:
using tmsh reset-stats operations outside the TMSH transactions


691706-4 : HTTP2/SPDY profile can cause orphaned connections

Component: Local Traffic Manager

Symptoms:
When tearing down a HTTP2 connection, which is composed of a clientside HTTP2 connection and 'n' serverside HTTP1.1 connections, the system might leave a subset of the 'n' serverside HTTP1.1 connection behind. Those left behind connections are still referencing the clientside PCB, which might result in a crash should they ever be expired, e.g., due to an AFM firewall policy change triggering the sweeper.

Conditions:
-- HTTP2 leaves serverside connections behind.
-- AFM firewall policy change occurs that triggers the sweeper.

Impact:
Orphaned connections might result in various behaviors, from a small memory leak to a tmm restart, which has the possibility of disrupting traffic.

Workaround:
None.


691670-4 : Rare BD crash in a specific scenario

Component: Application Security Manager

Symptoms:
BD crash or False reporting of signature ID 200023003.

Conditions:
JSON/XML/parameters traffic (should not happen with the enforce value signature).

Impact:
Failover, traffic disturbance in the core case. False positive violation or blocking in the other scenario.

Workaround:
Removing attack signature 200023003 from the security policy stops the issue.


691589-1 : When using LDAP client auth, tamd may become stuck

Component: TMOS

Symptoms:
When a virtual server uses an LDAP auth profile for client authentication, we can get into a state where all authentications timeout. This condition persists until tamd restarts. Traffic analysis between BIG-IP and LDAP server shows that the BIG-IP makes a TCP handshake with the server, then immediately sends FIN. Tamd cores may be seen.

Conditions:
Virtual server using LDAP auth profile

Impact:
Authentication to the virtual will fail until tamd is restarted.

Workaround:
bigstart restart tamd


691498-2 : Connection failure during iRule DNS lookup can crash TMM

Component: Global Traffic Manager (DNS)

Symptoms:
The TMM crashes in the DNS response cache periodic sweep.

Conditions:
The DNS resolver connection fails after a successful lookup response is cached. This has been reproduced with a failure due to a lost route. Other failures such as down ports do not cause a crash.

Impact:
The TMM cores and automatically restarts, leading to a temporary loss of service.

Workaround:
No known workaround.


691497-1 : tmsh save sys ucs <file> fails due to missing patch file in /config/.diffVersions

Component: TMOS

Symptoms:
The .diffVersions directory has config change-diffs saved into patch files every time tmsh saves the configs. This is used for diagnostic purposes only.

Conditions:
When doing a 'tmsh save sys ucs <file>', it is possible that a background 'tmsh save sys config' gets run at the same time, causing a patch file to be deleted that the ucs-save feature now expected to exist.

Impact:
The ucs-save feature complains about the missing patch file and exits.

Workaround:
Re-run the 'tmsh save sys ucs <file>' ignoring the missing patch file message. That missing file doesn't need to be restored.


691491-4 : 2000/4000, 10000, i2000/i4000, i5000/i7000/i10000, i15000, B4000 platforms may return incorrect SNMP sysIfxStatHighSpeed values for 10G/40G/100G interfaces

Component: TMOS

Symptoms:
2000/4000, 10000, i2000/i4000, i5000/i7000/i10000, i15000, B4000 platforms may return incorrect SNMP sysIfxStatHighSpeed values for 10G/40G/100G interfaces

Conditions:
-- 2000/4000, 10000, i2000/i4000, i5000/i7000/i10000, i15000, B4000 platforms.
-- SNMP query of network interfaces via OID sysIfxStatHighSpeed.

Impact:
Value returned for 10G/40G/100G interfaces may be incorrect.

Workaround:
Use OID sysInterfaceMediaActiveSpeed.


691338-1 : Using an iRule to change virtual servers prevents correct DAG detection for PBA and DNAT modes

Component: Carrier-Grade NAT

Symptoms:
When redirecting the traffic by using iRule 'virtual <virtual_server>' on a PBA or DNAT LSN pool associated virtual server, the system resets the connection and logs errors similar to the following:

err tmm2[19158]: 01670024:3: Unsupported DAG mode for LSN pool(/Common/session1_pool) mode PBA on interface _loopback
err tmm2[19158]: 01670024:3: Unsupported DAG mode for LSN pool(/Common/dnat_pool) mode DNAT on interface _loopback

This occurs because using an iRule to change virtual servers prevents correct DAG detection for PBA and DNAT modes.

Conditions:
-- LSN pool is configured in either PBA or DNAT mode.
-- An iRule redirects traffic to a different virtual server.

Impact:
Connections fail using this iRule.

Workaround:
To work around this issue, configure the lsn-pools with NAPT mode.


691287-2 : tmm crashes on iRule with pool command after string command

Component: Global Traffic Manager (DNS)

Symptoms:
tmm crashes when a pool command immediately follows a string command in an iRule, for example:
when DNS_REQUEST {
    pool [string tolower "Test.com"]
}

Conditions:
Similar GTM iRule with pool command after string command.
when DNS_REQUEST {
    pool [string tolower "Test.com"]
}

Impact:
Traffic disrupted while tmm restarts.

Workaround:
Do not use a pool command immediately after a string command in an iRule.


691048-2 : Support DIAMETER Experimental-Result AVP response

Component: Service Provider

Symptoms:
When the Diameter server returns an answer message with an Experimental-Result AVP, but doesn't have Result-Code AVP inside, then the server side flow is aborted.

Conditions:
Diameter answer message doesn't have Result-Code AVP available, but with Experimental-Result AVP.

Impact:
The server side flow is aborted.

Workaround:
Use iRule to insert Result-Code AVP in all Diameter answer messages.


690890-2 : Running sod manually can cause issues/failover

Component: TMOS

Symptoms:
If multiple instances of the system failover daemon are executed, improper behavior results. The system failover daemon is run internally by the system service manager (bigstart). When accidentally or intentionally executing the command 'sod', the second running instance will disrupt the failover system.

Conditions:
Accidentally or intentionally executing the command 'sod'.

Impact:
System might failover, reboot, or perform other undesirable actions that result in traffic interruption.

Workaround:
Do not attempt to invoke the 'sod' daemon directly. There is no use case for executing 'sod' directly, it is managed by 'bigstart'.


690778-2 : Memory can leak if the STREAM::replace command is called more than once in the STREAM_MATCHED event in an iRule

Component: Local Traffic Manager

Symptoms:
Memory leak; the memory_usage_stat cur_allocs will increase each time the iRule is invoked.

Conditions:
This occurs when using an iRule that calls the STREAM::replace command more than once in the iRule's STREAM_MATCHED event.

Impact:
Memory leak; eventually the system will run out of memory and TMM will restart (causing a failover or outage). Traffic disrupted while tmm restarts.

Workaround:
Change the way the iRule is written so that the STREAM::replace command is not called more than once in the iRule's STREAM_MATCHED event.


690166-2 : ZoneRunner create new stub zone when creating a SRV WIP with more subdomains

Component: Global Traffic Manager

Symptoms:
Creating SRV wideip will result in stub zone creation even there are already matching zones.

Conditions:
Creating SRV wideip with three more layers than existing zone.

Impact:
Unnecessary stub zones created.


690091 : mod_timer list corruption followed by BUG_ON() in timer-based function, cascade()

Component: TMOS

Symptoms:
The kernel detects an inconsistency in timer data structures and panics, with a silent reboot shortly afterward.

Conditions:
No specific conditions are required to encounter this issue. This is a timing-related race condition.

Impact:
Silent reboot. On a VIPRION platform, loss of cluster mgmt IP address.

Workaround:
None.


690042-2 : Potential Tcl leak during iRule suspend operation

Component: Local Traffic Manager

Symptoms:
TMM's Tcl memory usage increases over time, and does not decrease. Memory leak of Tcl objects might cause TMM to core.

Conditions:
-- iRules are in use.
-- Some combination of nested proc calls and/or loops must go at least five levels deep.
-- Inside the nested calls, an iRule executes a suspend operation.

Impact:
Degraded performance. TMM out-of-memory crash. A failover or temporary outage might occur. Traffic disrupted while tmm restarts.

Workaround:
None.


689982-2 : FTP Protocol Security breaks FTP connection

Component: Application Security Manager

Symptoms:
FTP Protocol Security breaks FTP connection.

Conditions:
-- ASM provisioned
-- FTP profile (Local Traffic :: Profiles : Services : FTP) with 'Protocol Security' enabled is assigned to a virtual server.

Impact:
-- RST on transaction.
-- bd PLUGIN_TAG_ABORT messages in mpidump.

Workaround:
Create and use a custom "FTP Security Profile" instead of the system default one.

1. Navigate to Security :: Protocol Security : Security Profiles : FTP.
2. Create a custom FTP Security Profile alongside the system default named 'ftp_security'.
3. Navigate to Security :: Protocol Security : Profiles Assignment : FTP.
4. From the Assigned Security Profile drop-down menu, choose the newly created custom FTP Security Profile, instead of the pre-selected system default 'ftp_security'.


689583-2 : Running big3d from the command line with arguments other than '-v' or '-version' may cause a GTM disruption.

Component: Global Traffic Manager

Symptoms:
Running big3d from the command line with arguments other than '-v' or '-version' might cause a GTM disruption. When viewing /var/log/gtm, you might see messages similar to the following:
 notice big3d[4131]: 012b0020:5: Executable /shared/bin/big3d timestamp is newer than (or the same as) /usr/sbin/big3d.
 notice big3d[4137]: 012b0018:5: Respawning to run /shared/bin/big3d.
 err big3d[4026]: 012b1015:3: Error 'Address already in use' attempting to bind to socket.

Conditions:
This occurs when attempting to get the big3d version and accidentally typing an invalid or nonsense argument or a valid argument that does not immediately cause big3d to exit. Here are some examples (note the double-dash in the first example):
 big3d --version
 big3d
 big3d -xyz
 big3d -d

Impact:
GTM server goes red momentarily.

Workaround:
There is no workaround other than not specifying an invalid or nonsense argument or a valid argument that does not immediately cause big3d to exit.


689577-2 : ospf6d may crash when processing specific LSAs

Solution Article: K45800333

Component: TMOS

Symptoms:
When OSPFv3 is configured and another router in the network performs a graceful restart, ospf6d may crash.

Conditions:
-- OSPFv3 in use.
-- Graceful restart initiated by another system.

Impact:
OSPFv3 routing will interrupted while the daemon restarts and the protocol re-converges.

Workaround:
Disabling graceful restart on other network systems will prevent ospf6d from crashing on the BIG-IP system. However, it will cause a routing interruption on a system that restarts.


689567-2 : Some WOM/AAM pages in the GUI are visible to users with iSeries platforms even when AAM cannot be provisioned

Component: TMOS

Symptoms:
Several pages in the Acceleration tab (e.g., Acceleration :: Quick Start : Symmetric Properties) display a warning message that directs you to provision AAM in order to access WOM utilities. These pages are visible even if it is impossible for you to provision AAM, which is confusing.

Conditions:
You have an iSeries platform with no AAM license.

Impact:
The impact is cosmetic only. The page is confusing because it suggests that AAM can be provisioned without the proper license (e.g., that WOM/AAM can be set up with only an LTM license), which it cannot. You can safely ignore the warning messages.

Workaround:
No workaround at this time.


689491 : cpu usage reported as 'stolen' on vcmp guests with 1-core or htsplit disabled

Component: TMOS

Symptoms:
CPU usage stats are incorrect and system looks idle when it's actually busy

Conditions:
vcmp guests with 1-core or htsplit disabled

Impact:
CPU stats are incorrect and it might make it difficult to trouble shoot problems.


689449-2 : Some flows may remain indefinitely in memory with spdy/http2 and http fallback-host configured

Component: Local Traffic Manager

Symptoms:
As a result of a known issue, in some circumstances the system may experience an unconstrained TMM memory growth when a virtual server is configured for spdy/http2 and http with fallback-host.

Conditions:
- VIP configured with spdy/http2 and http with fallback-host.

Impact:
TMM may eventually enter aggressive sweeper mode where this memory will be released. In the process it is possible that some legitimate connections will killed.

Workaround:
No workaround at this time.


689415 : APM configuration snapshots missing due to APMD's failure to detect TMM state transition

Component: Access Policy Manager

Symptoms:
User failed to log in with the following error message displayed on logon page:

Access policy configuration has changed on gateway. Please login again to comply with new access policy configuration.

In the /var/log/apm, there are error messages indicating configuration snapshots were found missing and the attempt to recreate them failed.

-- err apmd[14462]: 01490259:3: Exception occurred for memcache operation: AccessPolicyProcessor/ProfileAccess.cpp line:430 function: resetTimeout - Config snapshot could not be found
-- notice apmd[14462]: 01490165:5: Access profile: /Common/my_access_profile initialized with configuration snapshot catalog: /.0/tmm.session.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
-- notice apmd[14462]: 01490166:5: Current snapshot ID: 1506842644 retrieved from session db for access profile: /Common/my_access_profile
-- err apmd[14462]: 01490000:3: AccessPolicyProcessor/ProfileAccess.cpp func: "snapshotConfigVariables()" line: 358 Msg: EXCEPTION AccessPolicyProcessor/ProfileAccess.cpp line:298 function: snapshotConfigVariables - Config variable snapshot: Couldn't create catalog key (/.0/tmm.session.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx./Common/my_access_profile.1506842645)

Conditions:
1. APMD detects TMM restart
2. APMD then recreates configuration snapshots when TMM becomes ready.
3. TMM restarts and becomes ready again.
4. APMD checks TMM status again but concludes that TMM is still down.

Impact:
APM end users will not be able to log in.

Workaround:
Restart APMD to recover when there is configuration snapshot.


689375-2 : Unable configure 'Generic Alert' setting on SSL client/server profile through TMUI when 'Proxy SSL' is enabled

Component: TMOS

Symptoms:
TMUI hides several SSL client/server settings when 'Proxy SSL' is enabled, including the 'Generic Alert' setting, so you cannot set it.

Conditions:
Enable 'Proxy SSL' on SSL client/server profile in TMUI.

Impact:
TMUI hides many config settings, including 'Generic Alert'. You cannot modify 'Generic Alert' setting on SSL client/server profile using the GUI when 'Proxy SSL' is enabled.

Workaround:
Modify the same setting through TMSH modify client/server SSL profile command, as follows:

tmsh modify ltm profile client-ssl <profile_name> generic-alert disabled

tmsh modify ltm profile server-ssl <profile_name> generic-alert disabled


689361-2 : Overwrite configsync can change the status of a pool member from 'unchecked' to 'up' (gateway_icmp monitor)

Component: Local Traffic Manager

Symptoms:
It is possible for an overwrite-configsync to change an 'unchecked' monitor to 'up', when that unchecked monitor references a node that does not respond to ICMP requests. This may occur when a node does not respond to ICMP requests for exactly one of two paired devices, but a configuration change made to one device causes the 'up' status to be propagated to the 'unchecked' device.

Conditions:
Two pool members are monitored; and one references a node not responding to ICMP requests; and a gateway_icmp monitor is on both nodes; and an overwrite-configsync is initiated from a paired device, where the node does respond to ICMP requests from that paired device.

Impact:
The overwrite-configsync causes the 'unchecked' monitor to transition to 'up', when it should remain 'unchecked' for the device to which the node does not respond to ICMP requests.

Workaround:
Ensure network configuration such that a monitored node responds to ICMP requests from both (or neither) of each paired-device. Alternatively, initiate configuration changes only from the device to which the node will not respond to ICMP requests.


689343-1 : Diameter persistence entries with bi-directional flag created with 10 sec timeout

Component: Service Provider

Symptoms:
Diameter persistence entries have timeout value less than 10 seconds, although the configured persistence timeout is 120 seconds

Conditions:
When Diameter custom persistence "DIAMETER::persist key 1" bi-directional iRule is used.

Impact:
The persist timeout is less than 10 seconds, thus subsequent requests will be dispatched to other pool member.

Workaround:
Don't use bi-directional persistence iRule. Use AVP persistence type with session-id as the persist key.


689211-1 : IPsec: IKEv1 forwards IPv4 packets incorrectly as IPv6 to daemon after version was { v1 v2 }

Component: TMOS

Symptoms:
If you accidentally change an ike-peer version to { v1 v2 } for both IKEv1 and IKEv2 support then IKEv1 does not work when version is changed to { v1 }. Note: This is not a recommended action.

Packets from a remote peer after this appear to arrive via IPv6 and will not match the IPv4 config of the actual peer, so tunnels cannot be established.

Conditions:
Transiently changing an ike-peer version to { v1 v2 } before fixing it with 'version replace-all-with { v1 }' to target IKEv1 alone.

Impact:
IKEv1 tunnels cannot be established when the remote peer initiates. (If the local peer initiates, negotiation may succeed anyway, until the SA is expired or deleted.) After this, tmm forwards packets to racoon improperly.

Workaround:
After changing version to v1 alone, issue the following command to have the config work correctly:
 bigstart restart


689089-2 : VIPRION cluster IP reverted to 'default' (192.168.1.246) following unexpected reboot

Component: Local Traffic Manager

Symptoms:
The cluster configuration file can be lost or corrupted, resulting in the out-of-band cluster management IP reverting to the default value.

Conditions:
Unexpected system restart while the configuration file is being updated may cause the file to become corrupted. If this occurs, the following error will be logged during blade startup:

"err clusterd[8171]: 013a0027:3: Chassis has N slots, config file has 0, ignoring config file"

Where "N" is the number of physical slots in the chassis (2, 4, or 8).

Impact:
Management IP reverts to 192.168.1.246, resulting in loss of access to the chassis through the out-of-band management network.

Workaround:
If this occurs, the management IP can be restored using TMSH or the UI through an in-band self IP, or with TMSH through the management console port.


689002-2 : Stackoverflow when JSON is deeply nested

Component: TMOS

Symptoms:
When the returned JSON payload from iControl REST is very large and deeply nested, the JSON destruction could trigger stack overflow due to deep recursion. This will crash icrd_child.

Conditions:
Deeply nested JSON returned from iControl-REST.

Impact:
icrd_child process coredumps.

Workaround:
None.


688942-4 : ICAP: Chunk parser performs poorly with very large chunk

Component: Service Provider

Symptoms:
When an ICAP response contains a very large chunk (MB-GB), the BIG-IP system buffers the entire chunk and reevaluates the amount of data received as each new packet arrives.

Conditions:
ICAP server returns large payload entirely in a single chunk, or otherwise generates very large chunks (MB to GB range).

Impact:
The BIG-IP system uses memory to buffer the entire chunk. In extreme cases the parser can peg the CPU utilization at 100% as long as packets are arriving.

Workaround:
If possible, configure the ICAP server to chunk the response payload in mulitple normal sized chunks (up to a few tens of KB).


688841 : Configuration validation does not catch enabling DoS Application Security Behavioral DoS from Local Traffic Policy rule

Component: Advanced Firewall Manager

Symptoms:
You can create a DoS profile that enables Application Security Behavioral Detection and Mitigation and invoke that DoS profile from a Local Traffic Policy rule via the Enable L7DoS Action. However, the Application Security Behavioral Detection and Mitigation setting will be ignored. Only the default DoS profile attached directly to the Virtual Server can successfully enable Application Security Behavioral Detection and Mitigation.

Conditions:
-- DoS policy that enables Application Security Behavioral Detection and Mitigation.
-- Local Traffic policy rule that invokes that DoS policy.

Impact:
The system silently ignores attempts to enable DoS Application Security Behavioral Detection and Mitigation.

Workaround:
Enable DoS Application Security Behavioral Detection and Mitigation in a DoS profile attached directly to the Virtual Server.

Note: Although you can invoke any number of other DoS profiles via Local Traffic policy rules, they cannot successfully enable DoS Application Security Behavioral Detection and Mitigation.


688833-4 : Inconsistent XFF field in ASM log depending violation category

Component: Application Security Manager

Symptoms:
Depending on the violation category, the xff ip field is reported as 'xff_ip' and sometimes as 'xff ip'.

Conditions:
Viewing the XFF results in ASM log.

Impact:
This might cause problems with the syslog filters configured on the remote loggers.

Workaround:
Put in the rules that the client is using both 'xff ip' and 'xff_ip'.


688813 : Some ASM tables can massively grow in size.

Solution Article: K23345645

Component: Application Visibility and Reporting

Symptoms:
/var/lib/mysql mount point gets full.

Conditions:
Many combinations of IP addresses, Device IDs (and other ASM dimensions) in traffic over very long period of time (potentially weeks/months).

Impact:
While other dimensions are being collapsed correctly, the Device ID field is not being collapsed causing the growth in size.
-- High disk usage.
-- Frequent need to clear AVR data.

Workaround:
Manually delete AVR mysql partitions located in /var/lib/mysql/AVR.


688744-2 : LTM Policy does not correctly handle multiple datagroups

Component: Local Traffic Manager

Symptoms:
Policy in use where the conditions reference two or more datagroups, but only the conditions that refer to the first datagroup have any effect.

Conditions:
LTM Policy where the conditions reference two or more datagroups.

Impact:
LTM Policy conditions do not check against second and subsequent datagroups, resulting in policy not working as intended.

Workaround:
Only mitigation is to refactor the policy so that it does not refer to more than one datagroup-based condition.


688629-2 : Deleting data-group in use by iRule does not trigger validation error

Component: Local Traffic Manager

Symptoms:
iRule aborts due to failed commands, causing connflow aborts.

Conditions:
-- Delete a data group.
-- iRule uses that data-group on a virtual server

Impact:
In use data-group can be deleted without error. iRule aborts leading to connflow aborts.

Workaround:
Don't delete data-groups in use by an iRule.


688571-1 : Untrusted cert might be accepted by the server-ssl even though when 'untrusted-cert-response-control drop' is configured in the server-ssl profile.

Component: Local Traffic Manager

Symptoms:
If the server-ssl profile is configured with 'untrusted-cert-response-control drop', and the system receives the certificate from the backend server which is not trusted by current BIG-IP system, the expected behavior is that the system should end the connection.

But the current server-side behavior is that the system still accepts the untrusted certificate and establishes the SSL connection with backend server.

Conditions:
-- The BIG-IP system receives a certificate from the backend server that is not trusted by the BIG-IP system.

-- Configure the 'untrusted-cert-response-control drop' in the server-ssl profile.

-- The corresponding server-ssl is configured at the virtual server.

Impact:
Virtual server might communicate with the backend server that sends the untrusted certificate to the BIG-IP system. Untrusted cert could still be accepted by the server-ssl virtual server even though 'untrusted-cert-response-control drop' is configured in the server-ssl profile.

Workaround:
None.


688406-2 : HA-Group Score showing 0

Component: TMOS

Symptoms:
The 'show sys ha-group' command incorrectly displays a "0" for the total score even if the pools/trunks/clusters components have non-zero scores.

Conditions:
If the sys ha-group object is not currently assigned to any traffic-group.

Impact:
The total score is not calculated. An incorrect score value is displayed.

Workaround:
Refer to the component Score Contributions displayed using the following command: show sys ha-group detail.


688335-4 : big3d may restart in a loop on secondary blades of a chassis system

Component: Global Traffic Manager

Symptoms:
After big3d_install is run against a target system, and this target system is a multi-blade chassis, the big3d utility may begin restarting in a loop on all secondary blades of the target system. The primary blade is not affected, where big3d continues to run stable.

Conditions:
The following conditions are required to encounter this issue:

-- The big3d_install utility is used against a target system.
-- The target system is a multi-blade chassis.
-- The big3d_install utility picks the iQuery installation method (and not the SSH one).
-- The big3d_install utility incorrectly determines that the local version of the big3d utility should be copied to the remote system.

Impact:
big3d does not typically do anything on secondary blades, so this issue should have no immediate material impact.

However, should the cluster elect a new primary blade, and should big3d still be restarting on that blade, this could cause iQuery communication failures between that system and remote BIG-IP systems.

Workaround:
To stop secondary blades from restarting, manually restart big3d on the primary blade using the following command:
 bigstart restart big3d

To prevent this issue from happening, you can run the big3d_install by specifying that the SSH installation method be used using the following command:
 big3d_install -use_ssh <target IP>


688266-4 : big3d and big3d_install use different logics to determine which version of big3d is newer

Component: Global Traffic Manager

Symptoms:
The big3d_install utility includes logic to determine whether the local system should copy its version of the big3d daemon to the remote system specified by the user.

This logic is incorrect and may result in the local copy of the big3d daemon being unnecessarily copied to the remote system or not copied when actually necessary.

Conditions:
A user runs the big3d_install utility.

Impact:
If the local big3d daemon was unnecessarily copied over to the remote system, there is no tangible impact (other than the fact big3d restarts on the remote system, which is expected). Eventually, the remote system restores and uses its version of the big3d daemon.

If the local big3d daemon was not copied over when it should have been, then the remote system may continue to run an older version of the big3d daemon, which may impede iQuery communication.

Workaround:
If the local big3d daemon was unnecessarily copied over to the remote system, you do not need to perform any remedial action. The remote system will automatically resolve this situation by restoring the intended (i.e., newer) big3d version.

If the local big3d daemon was not copied over when it should have been, you can invoke the big3d_install utility using the -f argument, which forces an install of the big3d daemon regardless of the local and remote versions.


688177 : Local user with Administrator role may be changed to Guest role after BIG-IP software upgrade

Component: Device Management

Symptoms:
Following a BIG-IP software upgrade (for example, from version 11.5.4 to version 11.6.1), local users with Administrator role may be changed to Guest role.

Conditions:
The BIG-IP configuration includes one or more local accounts with Administrator role (other than the 'admin' user).

Please note that this issue does not occur on every upgrade, but has roughly a 10% probability of occurring.

Impact:
Administrator users other than 'admin' have no access after the upgrade.

The 'admin' user has to change the role of affected users from Guest back to Administrator after the upgrade.

Workaround:
The 'admin' user has to change the role of affected users from Guest back to Administrator after the upgrade.


688148-2 : IKEv1 racoon daemon SEGV during phase-two SA list iteration

Component: TMOS

Symptoms:
The wrong list linkage is iterated when phase-two SAs are deleted.

Conditions:
Deleting phase-two SAs, either manually or in response to notifications.

Impact:
IKEv1 tunnel outage until the racoon daemon restarts.

Workaround:
None.


688046-1 : Change condition and expression for Protocol Lookup agent expression builder

Component: Access Policy Manager

Symptoms:
Protocol lookup agent shows the incorrect condition and expression in the expression builder when included in the per-request policy.

Conditions:
This occurs when the protocol lookup agent is used in the expression builder for branching.

Impact:
Cannot follow successful branch in per-request policy.

Workaround:
To work around this issue:
1. Include Protocol lookup agent in the expression builder.
2. Click the 'change' link right next to the existing expression.
3. Go to the Advanced tab and change the expression to one of the following (depending on whether you are using HTTPS or HTTP):
-- "expr { [mcget {perflow.protocol_lookup.result}] == "https" }"
-- "expr { [mcget {perflow.protocol_lookup.result}] == "http" }"
4. Click Finished.


687937-2 : RDP URIs generated by APM Webtop are not properly encoded

Component: Access Policy Manager

Symptoms:
RDP URIs used to launch Native RDP resources form APM Webtop on Android/iOS/Mac are not properly encoded. As a result, RDP client might misinterpret the URI, in cases in which some RDP parameter contains the ampersand ( & ) symbol.

Conditions:
Native RDP resource is launched via RDP URI from APM Webtop.

One of RDP parameters contains symbol that should be URI encoded, e.g., '&'.

Impact:
RDP client misinterprets URI, which may result in failure to open RDP resource.

Workaround:
None.


687807-2 : The presence of a file with the suffix ".crt.csr" in folder /config/ssl/ssl.csr/ causes a GUI exception

Component: Local Traffic Manager

Symptoms:
When there is a file named *.crt.csr in folder /config/ssl/ssl.csr/, the webgui will get an exception on page: System ›› Device Certificates : Device Certificate ›› Device Certificate

A message, "An error has occurred while trying to process your request." appears.

Conditions:
The presence of a file with the suffix ".crt.csr" in folder /config/ssl/ssl.csr/

Impact:
the webgui will get an exception on page: System ›› Device Certificates : Device Certificate ›› Device Certificate

A message, "An error has occurred while trying to process your request." appears.

Workaround:
rename the csr file suffix from ".crt.csr" to ".csr"


687659 : A SAML IdP connector causes a sync failure when created

Component: TMOS

Symptoms:
A SAML IdP connector causes a sync failure when created.

Conditions:
SAML IdP connector contains an embedded certificate.

Impact:
Sync fails.

Workaround:
Force a full load sync immediately after.


687635-2 : Tmm becomes unresponsive and experiences restart

Component: Local Traffic Manager

Symptoms:
Under certain conditions, the tmm process can become unresponsive, and eventually be restarted by the watchdog process.

Conditions:
Problem occurs when there is an unexpected interaction between HTTP and SSL handlers during an abnormal connection shutdown.

Impact:
Tmm becomes unresponsive and restarts. Traffic disrupted while tmm restarts.

Workaround:
None.


687617-2 : DHCP request-options when set to "none" are reset to defaults when loading the config.

Component: TMOS

Symptoms:
Config load resets the request-option in "tmsh sys management-dhcp" to its default value when they are set to "none" in configuration.

Conditions:
- A config load in which request-option in "tmsh sys management-dhcp" is set to "none".

Impact:
User configuration is reverted as a side-effect of config load.

Workaround:
request-option specify the minimal set of configuration that DHCP server must provide as part of the lease. Setting it to "none" defeats the whole purpose of DHCP. It's better to set it to a minimal value like "routers, subnet-mask" in order to have management connectivity.


687534-2 : If a Pool contains ".." in the name, it is impossible to add a Member to this pool using the GUI Local Traffic > Pools : Member List page

Component: TMOS

Symptoms:
- Create a pool with name containing two dots (that is, the string '..')
- Go to the GUI Local Traffic :: Pools : Member List page and click the Add button to add a member.
- There is a No Access error preventing you from adding a member to the pool

Conditions:
This issue occurs when a pool name contains .. in the name.

Impact:
Cannot add a Member to the pool using the GUI.

Workaround:
Use tmsh to add pool members to an existing pool using a command similar to the following.
 tmsh modify ltm pool <pool name> members add { <member info> }


687368-2 : The Configuration utility may calculate and display an incorrect HA Group Score

Solution Article: K64414880

Component: TMOS

Symptoms:
The Configuration utility may calculate and display a high availability (HA) Group Score of 0, while in reality the correct HA Group Score is greater than 0.

Conditions:
This issue occurs when a particular HA Group object (for example, a Pool) has no available members, and the 'Minimum Member Count' option is not used (this is the default).

Impact:
This issue is cosmetic as it is limited to what the Configuration utility calculates and displays to the user. Internally, the system uses the correct HA Group Score to determine the role of the unit. However, it is possible for a BIG-IP Administrator to be mislead by this issue and take a wrong or unnecessary corrective action because of it.

Workaround:
You can use the TMSH utility from the command line to display the correct HA Group Score.


687353-2 : Qkview truncates tmstat snapshot files

Component: TMOS

Symptoms:
Qkview truncates the snapshot files it collects in /shared/tmstat/snapshots/.

Conditions:
Files are larger than 5 MiB, or the 'max file size' limit specified when running Qkview (the -s argument).

Note: 5 MiB is qkview utility's default maximum file size value.

Impact:
Snapshot data may not be collected in qkview. This may result in data being lost if the issue is only identified once important data has rotated out of history.

Workaround:
To specify no file size limit when collecting qkviews, use the following tmsh command:
qkview -s0


687343-2 : Running 'load sys config merge verify' will add new users to the PostGres database

Component: TMOS

Symptoms:
Running 'load sys config merge verify' will add new users to the PostGres database. The system posts an error similar to the following:

010719a2:3: PostgreSQL database error: ERROR: duplicate key value violates unique constraint "auth_user_pkey"
DETAIL: Key (name)=(admin1) already exists.

Conditions:
Issue occurs only under the following conditions:
-- 'load config merge verify' of configurations including user definition.
-- Attempt to create user with same name using 'load config merge', 'create user', or GUI options.

Impact:
It is not possible to use the verify argument when using 'load sys config merge' with configurations containing user definitions.

'verify' argument to 'load sys config' does not prevent or rollback side effects

Workaround:
Manually remove the user data from the PSQL database; from a bash prompt:

psql -U postgres

\c tmdb
DELETE FROM auth_user WHERE name='admin1'
DROP OWNED BY admin1
DROP ROLE admin1
DROP SCHEMA admin1 CASCADE
\q


687213-2 : When access to APM is denied, system changes connection mode to ALWAYS_DISCONNECTED

Component: Access Policy Manager

Symptoms:
When access to APM is denied, Edge Client goes into ALWAYS_DISCONNECTED mode. Hence, it does not retry to establish VPN tunnel.

Conditions:
-- Edge Client installed in ALWAYS_CONNECTED mode (locked client).
-- Access to APM is denied.

Impact:
No VPN tunnel is established, even if APM becomes accessible momentarily.

Workaround:
None.


687193 : Forged certificate serial number memory leak when SSL forward proxy is enabled.

Component: Local Traffic Manager

Symptoms:
One memory block has memory leak when SSL forward proxy tries to forge one certificate.

Conditions:
When SSL forward proxy is enabled.

Impact:
Serial number memory block of forged certificate is leaking.

Workaround:
None.


687044-1 : tcp-half-open monitors might mark a node up in error

Component: Local Traffic Manager

Symptoms:
The tcp-half-open monitor might a node or pool member up when it is actually down, when multiple transparent monitors within multiple 'bigd' processes probe the same IP-address/port.

Conditions:
All of the following are true:
-- There are multiple bigd processes running on the BIG-IP system.
-- There are multiple tcp-half-open monitors configured to monitor the same IP address.
-- One or more of the monitored objects are up and one or more of the monitored objects are down.

Impact:
The BIG-IP system might occasionally have an incorrect node or pool-member status, where future probes may fix an incorrect status.

Workaround:
You can use any of the following workarounds:

-- Configure bigd to run in single process mode by running the following command:
   tmsh set sys db bigd.numprocs value 1

-- Use a tcp monitor in place of the tcp-half-open monitor.

-- Configure each transparent monitor for different polling cycles to reduce the probability that an 'up' response from the IP address/port is mistakenly viewed as a response to another monitor that is currently 'down'.


686926-1 : IPsec: responder N(cookie) in SA_INIT response handled incorrectly

Component: TMOS

Symptoms:
IKEv2 negotiation fails when a responder uses N(cookie) in the SA_INIT response, because the BIG-IP system does not expect a second response with the same zero message_id always used by SA_INIT.

Conditions:
Any time a responder sends N(cookie) in the first response to SA_INIT from a BIG-IP initiator.

Impact:
The SA negotiation fails when a responder includes N(cookie) in a SA_INIT response, because a second response appears to have an out-of-order message ID when BIG-IP believe the first message_id of zero was already handled earlier.

Workaround:
None.


686816-2 : Link from iApps Components page to Policy Rules invalid

Component: TMOS

Symptoms:
In an application that contains a Local Traffic policy, the link from the Components page to the Rule will not be valid.

Conditions:
-- Application creates or contains a Local Traffic Policy.
-- Click the link from the iApps Components page to the Policy Rules page.

Impact:
Cannot navigate to the policy rule directly from the Components page.

Workaround:

686718-2 : VPN tunnel adapter stays up in some cases

Component: Access Policy Manager

Symptoms:
In some cases, VPN tunnel adapter created by VPN client stays up even when tunnel is disconnected.

Conditions:
Application launch on VPN establishment is configured on APM and launched application is not closed

Impact:
Cosmetic. No functionality impact. Subsequent launch of VPN will create a new tunnel adapter

Workaround:
Close the launched application


686685 : LTM Policy internal compilation error

Component: Local Traffic Manager

Symptoms:
To enable maximum performance, LTM Policies undergo a compilation process, where they are transformed to a compact binary representation. An issue was discovered where the transformation is being done incorrectly under certain circumstances.

Conditions:
While not common, certain LTM Policy combinations will be transformed to binary representation where certain internal parameters are incorrect.

Impact:
The tmm process may experience an unexpected restart, or a policy action may not run as expected.

Workaround:
None.


686563-2 : WMI monitor on invalid node never transitions to DOWN

Component: Local Traffic Manager

Symptoms:
A WMI monitor configured for an invalid node defaults to 'UP', and never transitions to 'DOWN'. Upon loading a configuration, a node defaults to 'UP' as an initial probe is sent based on the monitor configuration, and the node is then marked 'DOWN' as probes timeout or monitor responses indicate an error. However, an WMI monitor probe sent to a non-existent node is not detected as an error, and that node may persist in an 'UP' state (not transitioning to 'DOWN' as expected, such as after expiration of the configured monitor timeout).

Conditions:
WMI monitor is configured for an invalid node address, or for a node address on which no WMI service is running.

Impact:
The node persists in an 'UP' state, even though no WMI service is available, or that node does not exist.

Workaround:
An additional node monitor can be created to confirm the node is available (which may be a partial solution in some configurations). Using a non-WMI monitor (such as TCP) to probe availability of the WMI service on the target node may be possible in other scenarios.


686547-2 : WMI monitor sends logging data for credentials when no credentials specified

Component: Local Traffic Manager

Symptoms:
A properly configured WMI monitor requires username and password credentials; but when these are omitted from the configuration, logging data is sent in place of the username and password (with the monitored object likely being marked 'down'). Because username/password credentials are required, the monitor should have been identified as wrongly configured before the monitor is marked down.

Conditions:
A WMI monitor is configured without including the required username/password credentials.

Impact:
The monitored object will be marked 'down'.

Workaround:
Configure the WMI monitor to include the username/password credentials.


686517-1 : Changes to a parent policy, which has no active children, are not synced to the secondary chassis slots

Component: Application Security Manager

Symptoms:
Changes to a parent policy, which has no active children, are not synced to the secondary chassis slots

Conditions:
v13 or later
ASM provisioned
Having a Parent policy, which has no active children

Impact:
On a chassis failover, the new Primary slot will have an outdated version of the Parent policy

Workaround:
n/a


686470-2 : Enable AJAX Response Page or Single Page Application support causes the part of the web page failed to load.

Component: Application Security Manager

Symptoms:
AJAX requests are not sent, JavaScript errors, AJAX-based web-app malfunctions.

Conditions:
1a. Single page application enabled either via a DoS application profile or in an ASM policy.
1b. AJAX Response Page enabled via ASM policy.

2. Web Application client side code uses jQuery or any other AJAX clientside framework.

Impact:
AJAX request might not be sent, and the overall website's clientside functionality related to the AJAX requests might not work as expected.

Workaround:
Disable Single Page Application support.


686389-2 : APM does not honor per-farm HTML5 client disabling at the View Connection Server

Component: Access Policy Manager

Symptoms:
Current logic for determining whether to offer HTML5 client option works for Horizon 6.x (and earlier) but it does not work for Horizon 7.x.

With Horizon 7.x, VMware has enhanced the XML so that each resource includes a flag to indicate whether HTML5 client is enabled (absence of <html-access-disabled/> tag). APM does not honor this flag to show HTML5 client option to APM end user only if it has been enabled for that resource.

Conditions:
-- APM webtop with a VMware View resource assigned.
-- HTML5 Access disabled for some of the RDS farms managed by the broker.

Impact:
APM offers HTML5 client launch option and actually runs it if requested, although it is disabled at the backend.

Workaround:
There is no workaround at this time.


686307-2 : Monitor Escaping is not changed when upgrading from 11.6.x to 12.x and later

Component: Local Traffic Manager

Symptoms:
When upgrading, monitor attributes such as receive string and send string might contain escape sequences that must be processed after the upgrade. However, due to a problem introduced by the LTM policy upgrade script, this processing is not performed, resulting in monitors not functioning correctly after the upgrade.

Note: Without LTM policies in the configuration, monitors upgrade without problem.

Conditions:
-- Upgrading and rolling forward monitor configuration data.
-- LTM policy data present.

Impact:
Monitors may not work after upgrade.

Workaround:
No workaround at this time.


686228-2 : TMM may crash in some circumstances with VLAN failsafe

Solution Article: K23243525

Component: Local Traffic Manager

Symptoms:
TMM may crash when managing traffic in response to the VLAN failsafe traffic generating mechanisms

Conditions:
- VLAN failsafe is configured with low timers.
- VLAN failsafe is triggered and multiple responses are received for traffic generating in fast succession.

Impact:
A TMM may core file may be produced. Traffic disrupted while tmm restarts.

Workaround:
Relax the timer to the default VLAN failsafe timer setting.


686124-2 : IPsec: invalid SPI notifications in IKEv1 can cause v1 racoon faults from dangling phase2 SA refs

Component: TMOS

Symptoms:
Deleting SAs on a remote peer can cause improper handling in the IKEv1 racoon daemon when invalid SPI notifications are processed.

Conditions:
Events causing deletion of phase one IKE SAs.

Impact:
IPsec IKEv1 tunnels will halt or restart. Connectivity between remote private networks will be interrupted.

Workaround:
None.


686111-2 : Searching and Reseting Audit Logs not working as expected

Component: TMOS

Symptoms:
Clicking the Search and Reset buttons on Audit Logs might post the following error message: An error has occurred while trying to process your request.

Conditions:
Clicking the 'Search' or 'Reset' button on Audit Logs.

Impact:
Cannot search Audit Logs.

Workaround:
Use tmsh or bash.


685820-2 : Active connections are silently dropped after HA-failover if ASM licensed and provisioned but AFM is not

Component: Advanced Firewall Manager

Symptoms:
If ASM licensed and provisioned, but AFM is not licensed/provisioned, active connections are silently dropped after HA-failover.

In earlier versions, active connections were reset after HA-failover if only ASM was licensed/provisioned. When AFM is also licensed/provisioned, existing active connections were always silently dropped after HA-failover.

Conditions:
-- ASM licensed and provisioned, but AFM is not licensed/provisioned.
-- HA-failover occurs.

Impact:
ASM client connections are not reset, but are silently dropped after HA-failover event.

Workaround:
None.


685787 : SMTP Profile: "Use Authentication" cannot be disabled using the GUI

Component: Application Visibility and Reporting

Symptoms:
Once the "Use Authentication" option has been enabled in an SMTP profile, disabling this option using the GUI does not successfully disable this setting.

Conditions:
N/A

Impact:
N/A

Workaround:
Disable the "Use Authentication" option using tmsh by running the following command:
modify sys smtp-server <profile-name> authentication-disabled


685743-4 : When changing internal parameter 'request_buffer_size' in large request violations might not be reported

Component: Application Security Manager

Symptoms:
When the internal 'request_buffer_size' is set to a large value, long requests might be blocked, and no violation is reported.

Conditions:
-- Internal parameter 'request_buffer_size' is set to a large value (~50 KB or larger).
-- Request is long (~50 KB or longer).
-- Violations found.

Impact:
Requests might be blocked, and no reason is reported.

Workaround:
Reset internal 'request_buffer_size' to default.


685708 : Routing via iRule to a host without providing a transport from a transport-config created connection cores

Component: Service Provider

Symptoms:
Using MR::message route command without specifying a transport to use (virtual or config) will core if the connection receiving the request was created using a transport-config.

Conditions:
Using MR::message route command without specifying a transport to use (virtual or config) will core if the connection receiving the request was created using a transport-config.

Impact:
Traffic disrupted while tmm restarts.

Workaround:
Specify a transport to use for creating a new outgoing connection in the MR::message route command.


685615-3 : Incorrect source mac for TCP Reset with vlangroup for host traffic

Solution Article: K24447043

Component: Local Traffic Manager

Symptoms:
BIG-IP outbound host TCP RST packets have incorrect source-mac-address.

Conditions:
BIG-IP host traffic is exiting via VLANs in a VLAN group.

Impact:
TCP Reset for traffic exiting the BIG-IP system with incorrect source-mac-address, which could include monitor traffic.

Workaround:
Use transparent mode on the VLAN group.


685582-6 : Incorrect output of b64 unit key hash by command f5mku -f

Component: TMOS

Symptoms:
The output of the b64 unit key hash is inconsistent upon each 'f5mku -f' command, whereas the hex version of the unit key hash was always correct/consistent.

Conditions:
Viewing output of 'f5mku -f' command.

Impact:
Inconsistent output of the b64 unit key.

Workaround:
Adding the verbose option (v) to the f5mku command will print additional information. The following command prints the hex version of the unit key header hash, which will be stable and can be used to detect changes to the unit key:

 f5mku -vf

For example:

# f5mku -vf
...
-- hdr.hash = c9:0d:13:2a:74:d4:7e:31:a4:78:5e:c8:3e:9c:b5:3d:7b:65:9c:7d
...


685519-2 : Mirrored connections ignore the handshake timeout

Component: Local Traffic Manager

Symptoms:
Mirrored connections that do not complete the TCP 3-way-handshake do not honor the configured TCP handshake timeout on active and standby systems.

Conditions:
High availability mirroring enabled on virtual server with attached FastL4 profile.

Impact:
Unestablished TCP sessions in the connection table stay open for the duration of the TCP idle-timeout.

Workaround:
None.

Component: Application Security Manager

Symptoms:
No requests in request log when partition selected, while they can be seen when 'All [Read Only]' is selected.

Conditions:
Select a partition whose default route domain is not 0 (zero).

Impact:
No requests in request log.

Workaround:
As a partial workaround, you can use [All], but it's read only.


685110-2 : With a non-LTM license (ASM, APM, etc.), ephemeral nodes will not be created for FQDN nodes/pool members.

Solution Article: K05430133

Component: Local Traffic Manager

Symptoms:
1. FQDN Node/pools fails to populate with members.

2. An error similar to the following is logged in /var/log/ltm when an FQDN node or pool member is created:

err mcpd[####]: 01070356:3: Ratio load balancing feature not licensed.

Conditions:
1. License a BIG-IP system with non-LTM license lacking the ltm_lb_ratio feature.
Such licenses include APM and/or ASM licenses for certain newer platforms which do not support the AAM module.
Affected platforms include certain iSeries and Virtual Edition (VE) releases.
2. Configure an FQDN node/pool member. Do not specify a 'ratio' value.

Impact:
Unable to use FDQN nodes/pool members with non-LTM license.

Workaround:
None.


684937-2 : [KERBEROS SSO] Performance of LRU cache for Kerberos tickets drops gradually with the number of users

Component: Access Policy Manager

Symptoms:
APM performance of handling HTTP request drops gradually when Kerberos SSO is being used over period of time.
Websso process CPU usage is very high during this time. The latency can vary between APM end users.

Conditions:
-- A large number of APM end users have logged on and are using Kerberos SSO.
-- Running APM.

Impact:
Increased latency of HTTP request processing.

Workaround:
Reduce the number of cached Kerberos user tickets by lowering the cache lifetime.


684649 : Inconsistent DAGv2 state between B4400 blades after upgrade

Component: TMOS

Symptoms:
B4400 blades in the VIPRION chassis might encounter inconsistent DAGv2 state after upgrading from v12.1.x to v13.0.0 or v13.1.0. You might see messages similar to the following continuously logged into /var/log/tmm on the Standby unit:

notice CDP: Selected DAG state from primary PG 0 for CMP state 03 with clock 6765

Conditions:
Upgrading VIPRION B4400 blades from v12.1.x to v13.0.0 or v13.1.0.

Impact:
There is no traffic impact on the Active BIG-IP system, but the issue causes the Standby BIG-IP system to constantly update its DAGv2 table.

Workaround:
Reboot one of the B4400 blades in the Active BIG-IP system.


684399-3 : Connectivity profiles UI shows (Not Licensed) when LTM base is presented

Component: Access Policy Manager

Symptoms:
In APM, the connectivity profile UI shows (Not Licensed) when LTM base is presented

Conditions:
when LTM and APM is provisioned.

Impact:
UI shows FEC profile as not licensed. But user can still choose FEC profile.

Workaround:
Ignore the not licensed warning.


684391-2 : Existing IPsec tunnels reload. tmipsecd creates a core file.

Component: TMOS

Symptoms:
Existing IPsec tunnels reload. tmipsecd creates a core file.

Conditions:
Although an exact replication of the issue has not been reliable, the one instance occurred after the following conditions:
-- Remote peer repeatedly tries to establish a tunnel.
-- The IPsec IKEv1 daemon 'racoon' is dead.

Impact:
Existing IPsec tunnels reload when tmipsecd aborts. tmipsecd creates a core file.

Workaround:
None.


684369-1 : AFM ACL Rule Policy applied on Standby device

Component: Advanced Firewall Manager

Symptoms:
In a Active/Standby setup, with a Virtual Server configured to Mirror Connection State, the Standby Device is aware of the state of connections. The Standby device apart from maintaining the state of connections, need not apply ACL policy to the mirrored connections.

But in a specific case where a ACL Policy happens to have Rule with Schedules attached, the Standby happens to apply policy on mirrored connections, which also generates ACL rule hit logs.

Conditions:
1) Active/Standby device setup.
2) Virtual Server with Connection Mirroring enabled.
3) ACL Policy with a Rule having a Schedule attached, and during periods of transition when a Schedule may cause a Rule to be enforced or expired.

Impact:
Does not impact handling of traffic.

Generation of ACL Rule hit logs from Standby is unexpected, and is not desirable.

Workaround:
Objective:
- Disable sweeper applying ACL policy on Standby device.
- Sys DB tunable must disable only on Standby device. Because sys db settings are auto-sync'd to Active device as well, you must do so using the following procedure.
 
Steps to Apply Sys DB setting only on Standby device:
1. Turn off auto-sync for the device-group.
2. Apply settings just before Rule Schedule expiry on Standby device.
3. Wait till Rule Schedule change takes effect.
4. Revert the settings to normal, and enable auto-sync again.


TMSH Command Sequence:

root@(BIG-IP-primary)(cfg-sync In Sync)(Standby)(/Common)(tmos)
 # list sys db tm.sweeper.flow.acl value

 sys db tm.sweeper.flow.acl {
    value "enable" <<<< Set this to 'disable'
 }

root@(BIG-IP-primary)(cfg-sync In Sync)(Standby)(/Common)(tmos)
 # modify cm device-group <device-group-for-failover> auto-sync disabled

root@(BIG-IP-primary)(cfg-sync In Sync)(Standby)(/Common)(tmos)
 # modify sys db tm.sweeper.flow.acl value disable

root@(BIG-IP-primary)(cfg-sync Changes Pending)(Standby)(/Common)(tmos)
 # list sys db tm.sweeper.flow.acl value

 sys db tm.sweeper.flow.acl {
    value "disable"
 }

On Active, it's still 'enable':

root@(BIG-IP-secondary)(cfg-sync Changes Pending)(Active)(/Common)(tmos)
 # list sys db tm.sweeper.flow.acl value

 sys db tm.sweeper.flow.acl {
    value "enable"
 }

Enable auto-sync again:

root@(BIG-IP-primary)(cfg-sync In Sync)(Standby)(/Common)(tmos)
 # modify cm device-group <device-group-for-failover> auto-sync enable

Might have to issue this run command if the device is reported as 'requiring sync'.

root@(BIG-IP-primary)(cfg-sync Changes Pending)(Standby)(/Common)(tmos)
 # run cm config-sync to-group <device-group-for-failover>


684333-2 : PEM session created by Gx may get deleted across HA multiple switchover with CLI command

Component: Policy Enforcement Manager

Symptoms:
PEM sessions may get cleaned up with terminate cause of FATAL GRACE TIMEOUT, if multiple high availability (HA) failover is being performed using the following command: tmsh run sys failover standby.

Conditions:
Multiple HA failover performed using the following command: tmsh run sys failover standby.

Impact:
PEM session created using Gx may get deleted.

Workaround:
Initiate failover using alternate commands, such as the following:
 tmm big start restart.


684325-2 : APMD Memory leak when applying a specific access profile

Component: Access Policy Manager

Symptoms:
Access profile having CheckMachineCert agent, while updating profile using 'Apply access policy', each time it leaks 12096 bytes of memory.

Conditions:
-- Access profile configured with agent 'CheckMachineCert'.
-- Repeatedly update the profile using 'Apply access policy'.

Impact:
APMD process stops after repeated application of the script.

Workaround:
None.


684218-2 : vADC 'live-install' Downgrade from v13.1.0 is not possible

Component: TMOS

Symptoms:
vADC v13.1.0 has a new storage format that is incompatible with earlier versions. It should be possible to use the '--format' option of 'image2disk' to downgrade a v13.1.0 vADC system, but it is not.

Conditions:
Running v13.1.0, attempt software downgrade to 11.5.4, for example:

image2disk --format=volumes --nosaveconfig 11.5.4

Impact:
request is not allowed. no changes are made.

Workaround:
deploy a new 11.5.4 software image via the hypervisor environment

683767-2 : Users are not able to complete the sync using GUI

Component: TMOS

Symptoms:
A validation error occurred while syncing to a remote device
Sync error on unitA.lab.local: Load failed from /Common/unitB.lab.local 01070080:3: The requested pool member is already in use as a self IP address (1.1.2.1)

The above is expected as unit B is unable to validate the config for unit A. Incremental sync adds and removes configuration on unit A, hence the error.

Conditions:
1.Units A and B in HA with manual incremental sync, unit B is active.
2.On unit B add a pool with a member having IP address matching the self IP of unit A. Then delete it.
3.create ltm pool p1 members add { 1.1.2.1:80 }
4.delete ltm pool p1
5.Try config-sync (using GUI). You will end up with a Sync Failed message:
  A validation error occurred while syncing to a remote device
Sync error on unitA.lab.local: Load failed from /Common/unitB.lab.local 01070080:3: The requested pool member is already in use as a self IP address (1.1.2.1

Impact:
Users are not able to complete the sync using GUI

Workaround:
using tmsh to force a full sync


683697-2 : SASP monitor may use the same UID for multiple HA device group members

Solution Article: K00647240

Component: Local Traffic Manager

Symptoms:
Under rare timing conditions, the SASP monitor running on one member of an HA group (failover device group) may use the same LB UID as another member of the device group.

The LB UID used to connect to the Server/Application State Protocol (SASP) Group Workload Manager (GWM) is required to be unique for each client connecting to the GWM.

As a result, only the first HA group member using the duplicated UID is able to successfully use the SASP monitor.

The SASP monitor instance running on the HA group member using the duplicated UID will fail to connect to the SASP GWM.

Conditions:
This occurs under rare timing conditions when using the SASP monitor on a BIG-IP system that belongs to an HA group.

It is possible that the necessary timing conditions may occur if the external SASP monitor daemon is forcibly restarted (such as for troubleshooting purposes).

Impact:
The SASP monitor is unable to monitor pool member availability on all members of the HA group.

Workaround:
Forcing the mcpd process to reload the configuration (as described in article K13030: Forcing the mcpd process to reload the BIG-IP configuration (https://support.f5.com/csp/article/K13030) allows recovery from this condition.

It is possible that less-intrusive measures such as restarting the external SASP monitor daemon (such as by sending a SIGTERM to the SASPD_monitor process) may also allow recovery. Due to the rare occurrence of this symptom, this solution has not been confirmed.


683508-2 : WebSockets: umu memory leak of binary frames when remote logger is configured

Workaround:
None.


683297-1 : Portal Access may use incorrect back-end for resources referenced by CSS

Component: Access Policy Manager

Symptoms:
If HTML page contains reference to external CSS file with URL beginning with '//', then host-less references in this CSS file are handled incorrectly by Portal Access.

Conditions:
- HTML page at http://example.host/page.html:

    <link rel=stylesheet href=//another.host/some/path/my.css>

- and this CSS contains reference with absolute path like this:

    html { background-image: url(/misc/image/some.png); }

Portal Access uses 'http://example.host' as back-end for this image instead of correct 'http://another.host'.

Impact:
Web application may not work correctly.

Workaround:
Use iRule to correct back-end host.


683177-1 : Can't drilldown or filter by 'Client Countries'

Component: Application Visibility and Reporting

Symptoms:

2. Delete line 171: (dim_authz_filter=vip_crc).
3. Issue the command: bigstart restart monpd.


683131-2 : Hotfix install fails on vCMP guest when both guest and host have the same base version ISO present

Component: TMOS

Symptoms:
BIG-IP software installations will fail and report a status of:

    waiting for cleanup; multiple base builds found (BIG-IP 13.0.0)

Conditions:
- Perform software installation in a vCMP guest when guest is running v13.0.0 or newer.
- Ask the guest to install a hotfix (e.g. "tmsh install /sys software hotfix 13.0.0-hf2.iso volume HD1.2 create-volume") to a boot location that does not have a base software version installed.
- Hypervisor has a valid copy of the the correct base image (e.g. v13.0.0 build 0.0.1645)
- Guest has a valid copy of the correct base image (e.g. v13.0.0 build 0.0.1645)

Impact:
Software installation fails, and will not complete/continue.

Workaround:
Delete the base software image from either the hypervisor or guest's file system


683113-2 : [KERBEROS SSO][KRB5] The performance of memory type Kerberos ticket cache in krb5 library drops gradually with the number of users

Component: Access Policy Manager

Symptoms:
APM performance of handling HTTP request drops gradually when Kerberos SSO is being used over a period of time.

Websso CPU usage is very high.

Conditions:
-- A large number of APM end users have logged on and are using Kerberos SSO.
-- Running APM.

Impact:
Increased latency of HTTP request processing.

Workaround:
Reduce the number of cached Kerberos user tickets by lowering the cache lifetime.


683061-3 : Rapid creation/update/deletion of the same external datagroup may cause core

Component: Local Traffic Manager

Symptoms:
Sep 6 14:22:04 EDCF5EXT01 notice tmm[15187]: 01010259:5: External Datagroup (/Common/MAC_Address_Check_Poland) queued.
Sep 6 14:22:04 EDCF5EXT01 notice tmm[15187]: 01010259:5: External Datagroup (/Common/MAC_Address_Check_Poland) queued for update.
Sep 6 14:22:05 EDCF5EXT01 err tmm[15187]: 01010258:3: External Datagroup (/Common/MAC_Address_Check_Poland) creation failed: initial load error, deleting.

Conditions:
Using external datagroup, rapidly creating updating and then deleting it.

Impact:
TMM fails

Workaround:
Allow TMM enough time to finish processing external data-group before starting another operation. Depending on the size of the datagroup anywhere from 1s to 10s or more may be needed. The LTM log can be examined for the create/finished message to help determine how much wait time is required.


683029-5 : Sync of virtual address and self IP traffic groups only happens in one direction

Component: TMOS

Symptoms:
If you have a virtual address and a self IP that both listen on the same IP address, changing the traffic group of the self IP will make an equivalent change to the traffic group of the virtual address. However, this does not work in reverse. Changing the traffic group of the virtual address will not cause a change of the traffic group of the self IP.

Conditions:
You have a virtual address and a self IP that both listen on the same IP address. (The subnet mask need not be the same.)

Impact:
This is by design, but is counterintuitive, and there is no warning message that this is the case. Setting the traffic group on both objects will always work properly.

Workaround:
Care should be taken to ensure that the desired traffic group is set on both objects.


682751-6 : Kerberos keytab file content may be visible.

Component: Access Policy Manager

Symptoms:
Kerberos keytab file content may be visible.

Conditions:
Import a Kerberos keytab file.

From the command line, check the file permissions. It is readable.

Impact:
keytab is similar to a private key file and should not be readable.

Workaround:
Use chmod to change the keytab file permission manually so that it is not world-readable.


682682-2 : tmm asserts on a virtual server-to-virtual server connection

Component: Local Traffic Manager

Symptoms:
tmm might crash when using a virtual server-to-virtual server connection, and that connection has a TCP profile with keepalive configured.

Conditions:
-- L7 virtual server-to-virtual server connection (Virtual command, cpm rule, etc.).
-- TCP profile with keepalive configured.
-- (Deflate profile.)
-- At the beginning of the connection, there is a stall for longer than the specified keepalive timer interval.
-- The received response decompresses to a size that is greater than the advertised window size on the first virtual server's TCP stack.

Impact:
Shortly after the keepalive packet is received, which then is decompressed, the assert is triggered, and tmm restarts. Traffic disrupted while tmm restarts.

Workaround:
Remove keepalive from the TCP profiles of the two virtual servers involved.


682671-2 : The username is updated in the alert dashboard even if login validation fails.

Component: Fraud Protection Services

Conditions:
This occurs when the following conditions are met:
 -- 'trigger iRule' is enabled on the FPS profile.
 -- ANTIFRAUD::username <user> command is used in the ANTIFRAUD_LOGIN Tcl event.
 -- 'login validation' is enabled on the FPS profile.

Impact:
The new username will be updated in previous alerts in the alert dashboard.

Workaround:
Use the ANTIFRAUD::username <user> command only if ANTIFRAUD::result is SUCCESS.

Note: Reports to the risk engine will not contain the new username.


682500-3 : VDI Profile and Storefront Portal Access resource do not work together

682271-1 : Portal Access may handle JavaScript getter/setter definitions incorrectly

Component: Access Policy Manager

Symptoms:
In JavaScript, literal object definition may contain getter/setter definitions for some property, for example:

var c = { get a() { return a; }, set a(v) { if (v) a = v; } };

The object 'c' has the property 'a' with explicit getter/setter functions.

If name of such property is equal to any name to be rewritten, then Portal Access may generate incorrect JavaScript code.

Conditions:
- JavaScript code with literal object definition;
- Property with getter/setter definition in this object;
- Property name is one of rewritten names, like 'location' or 'onerror'.

Impact:
JavaScript code cannot be executed due to incorrect syntax after rewriting.

Workaround:
Use iRule to replace rewritten property names by original ones.


682213-2 : TLS v1.2 support in IP reputation daemon

Solution Article: K31623549

Component: TMOS

Symptoms:
The IP reputation daemon opens SSL connections to the Webroot BrightCloud server using TLS 1.0 protocol.

Conditions:
This occurs when using IP reputation.

Impact:
Because IP reputation services are used to accept/deny connections to critical business applications, there might be concerns about the service. Also some configurations might require that all transactions exfiltrating a PCI-controlled environment leverage secure protocols and ciphers, which won't be the case for IP reputation services.

Workaround:
None.


682043-2 : Chrome v60 and newer might incorrectly report that F5 VPN and F5 EPI status

Solution Article: K41041660

Component: Access Policy Manager

Symptoms:
Chrome v60 and newer might incorrectly report that F5 VPN and F5 EPI applications have not provided any status update to the browser. However, both applications are being launched and function properly.

Conditions:
Chrome v60 and newer on Microsoft Windows, Apple Macintosh, or Linux-based systems.

Impact:
F5 VPN: the webtop displays the following message:
 Waiting for Network Access Application status.

VPN or Application Tunnels work properly, and the APM end user may safely close the message box.

F5 EPI: the webtop displays the following message:
 Waiting for Endpoint Inspection status.

The latter message never goes away; however, F5 EPI applications are launched and function properly, and Security checks are performed in the background. Unless the APM end user refreshes the browser screen, the Access Policy never moves forward, causing browser never to refresh the page.

Workaround:
Use another browser: Internet Explorer 11, Microsoft Edge, Mozilla Firefox, or Safari, as available.

If using F5 EPI, refreshing the page after a one-minute since the check start should advance the position in the Access Policy, allowing the APM end user to properly log in.

Failover multicast configuration does not work.

Workaround:
Specify a multicast IP address under 'Failover Multicast Configuration' for network failover.


681757-2 : Upgraded volume may fail to load if a Local Traffic Policy uses the forward parameter 'member'

Solution Article: K32521651

Component: Local Traffic Manager

Symptoms:
In response to this issue, you might see the following symptoms:
-- System remains inoperative
-- Screen alerts similar to the following are posted: 'Configuration has not yet loaded'.
-- Configuration fails to load after upgrade to v12.1.0 or higher.

The system records an error message similar to the following in the ltm log file:

 emerg load_config_files: "/usr/bin/tmsh -n -g load sys config partitions all " - failed. -- 010716de:3: Policy '/Common/Policy', rule 'Policy-Rule'; target 'forward' action 'select' does not support parameter of type 'member'. Unexpected Error: Loading configuration process failed.

Conditions:
Local Traffic Policy with a forward action that selects a target of type 'member'.

Impact:
Configuration fails to load on upgrade.

Workaround:
Modify the local traffic policies to use a target type of 'node' before upgrading, or, after upgrading, edit the config file and modify 'member' to 'node' in the local traffic policy, and then reload the configuration.

681109-1 : BD crash in a specific scenario

Solution Article: K46212485

Component: Application Security Manager

Symptoms:
BD crash occurs.

Conditions:
A specific, non-default configuration with specific traffic.

The issue is much more likely to occur when the policy is not tuned correctly, in which case you might receive a potentially huge number of false positive attack signature matches on that payload. The crash might then occur if there is a subsequent 'Parameter value does not comply with regular expression' violation on that same payload.

For example, nothing prevents you from incorrectly associating a Content-Type and <type-value> with a Request Body Handling parser that is not designed to parse that type of data, such as the following:
  Content-Type :: *xml* :: form-data

This configuration is likely to result in a very long list of false-positive attack signatures. Because of the big message generated, The regex violation which is also likely to happen on the payload cannot be added to the filled message, which causes the crash.

Impact:
Failover, traffic disturbance.

Workaround:
In order to prevent this, correctly configure the header-based-content-profile property on URLs for cases where an unusual header requires a specific, potentially unexpected parsing mechanism.

A correctly configured header-based-content-profile property on URLs appears as follows:

In URL Properties, the Header-Based Content Profiles section of the wildcard URL is by default applying the value and content signature. Here, you can associate Content-Type with <type-value> with <parser-type>. By default, the correct definitions are as follows:
 Content-Type :: *form* :: Form Data
 Content-Type :: *json* :: JSON
 Content-Type :: *xml* :: XML

680856-1 : IPsec config via REST scripts may require post-definition touch of both policy and traffic selector

Component: TMOS

Symptoms:
A new IPsec tunnel may not work after being configured over REST. While the configuration is correct, a log message similar to the following may appear in ipsec.log (IKEv2 example):

info tmm[24203]: 017c0000 [0.0] [IKE] [INTERNAL_ERR]: selector index (/Common/Peer_172.16.4.1) does not have corresponding policy

Conditions:
A new IPsec tunnel is configured over REST.

Impact:
The newly configured IPsec tunnel does not start.

Workaround:
The following methods cause the traffic-selector and ipsec-policy to be correctly related to one another:
-- Restart tmm.
-- Change the configuration, for example the Description field, of both the policy and the traffic selector. This may also be done using REST.


680838-1 : IKEv2 able to fail assert for GETSPI_DONE when phase-one SA appears not to be initiator

Component: TMOS

Symptoms:

680074-1 : TMM crashes when serverssl cannot provide certificate to backend server.

Component: Local Traffic Manager

Symptoms:
The back end server during SSL handshake requested a certificate from BIGIP, but the server ssl profile did not configure one and the 'Bypass on Client Cert Failure' was enabled. Server side BIG-IP SSL then asked the client side SSL to convert itself to 'passthrough'. But the client side SSL handshake had already closed (tcp state of this flow was at TCPS_CLOSE_WAIT), sp->closing was true and sp->prf had been set to NULL. The event handler for SSL_TCL_METHOD_SET_PASSTHRU dereferenced a NULL pointer at this code sp->prf->stat.

Conditions:
The back end server during SSL handshake requested a certificate from BIGIP, but the server ssl profile did not configure one and the 'Bypass on Client Cert Failure' was enabled.

Impact:
The client side SSL handshake had already closed (tcp state of this flow was at TCPS_CLOSE_WAIT), sp->closing was true and sp->prf had been set to NULL. The event handler for SSL_TCL_METHOD_SET_PASSTHRU dereferenced a NULL pointer at this code sp->prf->stat. Traffic disrupted while tmm restarts.

Impact:
The operation times out and there is no way to configure the iControl REST timeout value.

Workaround:
None.


679687 : LTM Policy applied to large number of virtual servers causes mcpd restart

Component: Local Traffic Manager

Symptoms:
When a large policy (on the order of several dozen rules), is applied to a large number of virtual servers (on the order of hundreds), the mcpd process compiles the policy to an optimized, intermediate form for each virtual server. The compilation occurs in the mcpd process, and because it becomes so busy/non-responsive, a watchdog process intervenes and restarts the mcpd process.

Conditions:
-- Relatively large policy (~30 or more rules) applied to large number of virtual servers (~100 or more).
-- Creating a draft of the policy that is currently applied to those virtual servers, when a similarly attached policy is published.

Impact:
The mcpd process becomes unresponsive and is reset by a watchdog process.

Workaround:
Two possible workarounds:
-- Make copies of the policy and apply a different copy of policy to different subsets of virtual servers.
-- Implement the policy using iRules.

Symptoms:
When HTTP2 connection's parameters are negotiated, either side may report about its limits in SETTINGS type frame where one of the parameters SETTINGS_MAX_HEADER_LIST_SIZE determines a maximum size of headers list it is willing to accept. BIG-IP incorrectly interchanged this parameter with another one called SETTINGS_HEADER_TABLE_SIZE, limiting value of the former one to 32,768.

Conditions:
HTTP2 is configured and an opposite endpoint (user agent using HTTP2 protocol) tries to set SETTINGS_MAX_HEADER_LIST_SIZE to a value above 32,768.

Impact:
BIG-IP doesn't accept the value and terminates the connection using GOAWAY frame with PROTOCOL_ERROR as a reason.

Component: TMOS

Symptoms:
When an IPsec Security Association (SA) does not exist on a remote IPsec peer, the BIG-IP system might be sent an INVALID-SPI notification, but might not delete the SA. The IPsec tunnel might not be renegotiated until the deleted SAs on the BIG-IP system are removed manually or age out.

Conditions:
-- The BIG-IP system and remote peer communicate over a lossy network.
-- The remote peer prematurely deletes an IPsec SA.

Impact:
IPsec tunnel appears to be up but suffers a connectivity loss until the SPIs are manually deleted or age out.

Workaround:
Manually delete the SA.


676854-2 : CRL Authentication agent will hang waiting on unresponsive authentication server.

Component: Access Policy Manager

Symptoms:
Some authentication requests never complete. APMD responsiveness degrades over time and eventually restarts.

Conditions:
The CRL Authentication server must be alive enough to accept connections but busy enough to drop requests without closing connections.

Impact:
APMD responsiveness degrades over time, usually weeks, before eventually restarting.

Workaround:
Restarting the CRL Authentication server usually releases the waiting threads and restores APMD responsiveness.
Using a BIG-IP monitor for the CRL backend can detect the issue and allow recovery before the need for APMD to restart.

676442-1 : Changes to RADIUS remote authentication may not fully sync

Component: TMOS

Symptoms:
With multiple devices in a sync group, changes to remote authentication (for example, changes made using commands such as: tmsh modify auth radius system-auth servers replace-all-with { AAA_a AAA_b } ) will be effective on the device where the change was made.

And although the changes are synced to tmsh config on the other devices in the group, the changes are not effective on those devices, as may be observed by checking that the changes do not appear in /config/bigip/auth/pam.d/system-auth and /config/bigip/auth/pam.d/radius/system-auth.conf.

Conditions:
Devices in a sync group that will sync system-auth config.

Impact:
Changes to RADIUS authentication will not be effective throughout the device group.

Workaround:
After syncing RADIUS changes, run the following command on all devices:
 tmsh save sys config && tmsh load sys config.

MRF Diameter route table implementation does not add a persistence entry if the message is routed via an iRule.

Conditions:
-- MRF Diameter configured.
-- Message is routed via an iRule.

Impact:
A Diameter persistence entry will not be created. Since MRF Diameter persistence may be bidirectional, not having the persistence entry will keep message flowing in the opposite direction from being automatically routed via persistence.

Workaround:
Use an iRule to route messages directed towards the original client.


676092-2 : IPsec keeps failing to reconnect

Component: TMOS

Symptoms:
When an IPsec Security Association (SA) does not exist on a remote IPsec peer, the BIG-IP system might be sent an INVALID-SPI notification, but might not delete the SA. The IPsec tunnel might not be renegotiated until the deleted SAs on the BIG-IP system are removed manually or age out.

675597-1 : APM may prematurely close client-side RD Gateway connections on server-side disconnect

Component: Access Policy Manager

Symptoms:
APM may prematurely close client-side RD Gateway connections on server-side disconnect. APM log would contain 'CallOutput on empty outputSink' error message, in this case.
In rare cases, this might prevent RDP client from following RDP redirection (between RDP hosts in RDP farm), so client won't be able to connect via APM.

Conditions:
RDP server closes the connection before client.

Impact:
Rarely, this might prevent RDP client from following RDP redirection (between RDP hosts in RDP farm), so client won't be able to connect via APM.

Workaround:
None.


675539-2 : Inter-system communications targeted at a Management IP address might not work in some cases.

Component: Global Traffic Manager (DNS)

Symptoms:
Inter-system communications fail to connect to a BIG-IP system using the Management IP address.

Conditions:
This occurs if the device connection is configured between a Self IP address on one BIG-IP system and the Management IP address on another.

This occurs because the big3d daemon acts as a proxy, listening on the Management IP address and will send proper SSL connections (using SNI) to TMM (since TMM does not listen on the Management IP address).

This is not an issue if either of the following is true:

-- If the source of the connection is coming from the Management IP,
the connection is clear text. (Not SSL encrypted and thus does not use SNI)

-- The destination of the connection is a Self IP address, because TMM (via an iRule) will
handle the connection.

Impact:
Device sync operations do not work.

Workaround:
Do not use the Management IP address for between-device communications.


675399-1 : Network Access does not work when empty variables are assigned for WINS and DNS

Workaround:
If possible, use one of the following workarounds:

-- Turn off GSSAPI authentication on the mail server.
-- Use an alternate monitor type.


675326-1 : TMM core with Modify Header with 'remove header' option

Component: Access Policy Manager

Symptoms:
TMM core when Modify Header with 'remove header' option is used in policy before proxy select.

Conditions:
'Modify header' agent with 'remove header' option occurs before proxy select agent in per-request policy.

Impact:
TMM cores because HTTP data is not available at this point and the headers cannot be modified. Traffic flow is interrupted while TMM restarts.

Workaround:
Do not configure the per-request policy in such a way that the Modify Header agent is used before the Proxy Select agent. This is an invalid setup.


675236-1 : 'Require consistent IP address' does not apply to some management GUI menu items

Solution Article: K03293523

Component: TMOS

Symptoms:
The configuration setting 'System :: Preferences :: Require A Consistent Inbound IP For the Entire Web Session' ('sys http auth-pam-validate-ip' in tmsh) does not apply to some menu items, and acts as if the setting is enabled (that a consistent IP address is required) regardless of the BIG-IP configuration.

Conditions:
BIG-IP administrator accesses the configuration utility from more than one source IP address, using the same session cookie.

Impact:
The 'sys http auth-pam-validate-ip' setting is ineffective on some menu items. These include ASM, AVR, and APM menu items.

Workaround:
Ensure the source IP address used when accessing the configuration utility does not change mid-session. This could happen if your management session is being load balanced across multiple HTTP proxies, for example.


675232-4 : Cannot modify a newly created ASM policy within an iApp template implementation or TMSH CLI transaction

Conditions:
Zone already exists in ZoneRunner.
Trying to update it with a new email address.

Impact:
Confusion as to why the GUI is ignoring the new email address they entered.

Workaround:
The '@' (at sign) character is invalid for ZoneRunner email fields because it has other uses in zone files. Use a '.' (dot, or period) character instead of '@'.

Workaround:
bigstart restart tmm, after updating the classification rule with insert content action will fix the issue


673463-1 : SDD v3 symmetric deduplication may start performing poorly after a failover event

Component: Wan Optimization

Symptoms:
In certain high availability (HA) configurations and after performing specific maintenance tasks involving failovers, SDD v3 symmetric deduplication may start performing poorly for some file transfers.

Conditions:
This issue occurs when all of the following conditions are met:

1) A BIG-IP HA configuration is deployed on each side of the WOM tunnel.
2) Symmetric deduplication is configured to use the SDD v3 codec.
3) The far side BIG-IP HA configuration (from the perspective of the client performing the download) is failed over.
4) Clients attempt to download files that had previously been transferred through the BIG-IP units.

Impact:
Symmetric deduplication is severely impacted (virtually no hits) for files that had previously been transferred through the units. This causes the amount of data transmitted over the WAN to increase. Files that were not transferred previously through the units are not affected by this issue.

Workaround:
To eliminate the impacted symmetric deduplication condition, restart the receiving (i.e., the near) side.


673311-1 : When 'Web Scraping Configuration' has 'Bot Detection' set to 'Alarm', the type=7 JavaScript challenge is sent.

Component: Application Security Manager

Symptoms:
The JavaScript challenge type=7 is sent when it should not be.

The challenge should be sent only when 'Bot Detection' is set to 'Alarm and Block' or when 'Fingerprint Usage' or 'Persistent Client Identification' is enabled in 'Web Scraping Configuration'.

Conditions:
-- ASM Policy.
-- 'Bot Detection' set to 'Alarm' in 'Web Scraping Configuration'.

Impact:
After 10 requests to a qualified URL, the JavaScript challenge type=7 is sent back.

Workaround:
None.


673075 : Reduced Issues for Monitors configured with FQDN

Solution Article: K00879145

Component: Local Traffic Manager

Symptoms:
Monitors configured using FQDN might experience several edge cases in some deployment environments. For example, you might experience issues with FQDN-configured monitors when used in environments with volatile/unstable DNS servers, or when network configuration causes ICMP packets from an unreachable DNS server to be non-routable back to 'bigd'. In such cases, the monitor may experiences delay in rotating to the next available DNS server. This is due to complex edge cases that exist within the initial FQDN monitor implementation, where anomalous behavior is aggravated through some network configurations.

Conditions:
Monitors are configured using FQDN, and one-or-more environment conditions exist such as: Unstable DNS servers (i.e., 'flapping' DNS), or the network configuration causes ICMP packets from an unreachable DNS server to be non-routable back to 'bigd'.

Impact:
The monitor will not be updated with information from the (new) DNS server when the previous DNS server becomes unavailable. Other monitor behavior will continue to function normally.

Workaround:
In some cases network configuration can be changed to avoid these edge cases, such as: Ensuring stable DNS servers with only periodic rollovers to backup DNS servers; ensure network ICMP packets are routable back to 'bigd'. Alternatively, monitors may be configured without using FQDN.


673052-1 : On i-Series platforms, HTTP/2 is limited to 10 streams

Component: Local Traffic Manager

Symptoms:
On i-Series platforms, HTTP/2 is limited to 10 streams by licensing.

"HTTP2 limited to 10 concurrent streams: Web Accelerator feature not licensed." appears in /var/log/ltm

Conditions:
Using an i-Series platform where WAM is unlicensable.

Impact:
HTTP/2 performance may be less than desired


672988-1 : MCP memory leak when syncing data group objects

Solution Article: K03433341

Component: TMOS

Symptoms:
MCP will leak memory when syncing data group objects to peers in its device group. The memory leak can be seen by watching the umem_alloc_80 cache over time (with the tmctl utility).

Conditions:
A device group that syncs data group objects.

Impact:
MCP leaks a small amount of memory during each sync, and after an extended period of time might eventually crash.

Workaround:
None.


672963 : MSSQL monitor fails when monitored DB requires charset

Component: Local Traffic Manager

Symptoms:
MSSQL monitor is failing against database using non-native charset.

Conditions:

672828-1 : Different ASM logging profiles can have cross-impact on response logging decision

Component: Application Security Manager

Symptoms:
When attaching both local ASM logging profile and remote ASM logging profile to the same virtual server, response logging may not match configuration on logging profile for the remote logger.

Conditions:
-- Have both ASM local logging profile and ASM remote logging profile attached to the same virtual server.
-- Have response logging turned on for the remote profile, but disabled on the local.

Impact:
Response is not logged for the remote profile although it is turned on in config.

Workaround:
Enable response logging for local profile.


672491-1 : net resolver uses internal IP as source if matching wildcard forwarding virtual server

Solution Article: K10990182

Component: Global Traffic Manager (DNS)

Symptoms:
If a net resolver is created and contains a forwarding zone that matches an existing wildcard forwarding virtual server, an incorrect internal IP address will be used as the source.

Upon listener lookup for the net resolver, the wildcard virtual server will be matched to the forwarding zone resulting in a loopback IP address being used as the source IP address.

Conditions:
When creating an AFM policy that restricts FQDNs, a net resolver is needed to resolve the FQDNs. If the forwarding zone of this net resolver matches a wildcard server, DNS queries from the net resolver will use a loopback IP address as the source IP address.

Impact:
Failed DNS queries as a result of incorrect source IP address.

Workaround:
None.


672480 : WebSSO plugin process may become unresponsive in rare situations for Kerberos SSO

Solution Article: K26616425

Component: Access Policy Manager

Symptoms:
HTTP requests that are being processed by Kerberos SSO never leaves APM, and connections simply time out.

Conditions:
There is an issue in MIT krb5 library for calculating wait time for responses from KDC, which ends up with a negative value. This translates to infinite timeout by poll() syscall. At the same time, if all Kerberos requests to KDC are dropped (e.g., by a misconfigured firewall), Kerberos SSO never receives the responses, and Kerberos SSO never gives up on waiting for the KDC response (this is an issue in the library).

Impact:
A deadlock occurs within the Kerberos SSO. Eventually there will be a global deadlock, which causes this particular WebSSO process to be completely unresponsive for Kerberos SSO functionality. APM end users cannot access the backend.

Workaround:
For this issue to have a real impact, there must be an unresponded-to Kerberos request. To eliminate this possibility, make sure there is no firewall blockage, incorrect routing, etc., so that WebSSO always receives responses, even negative ones.

Note: WebSSO will never use infinite timeout when waiting for Kerberos responses, so even if a firewall blocks the Kerberos request, although Kerberos SSO does not function, it does not cause global unresponsiveness from the WebSSO process.


672312-1 : IP ToS may not be forwarded to serverside with syncookie activated

Component: Local Traffic Manager

Symptoms:

Symptoms:
bd daemon crash and writes a core file in the /shared/core directory.

Conditions:
-- ASM provisioned.
-- ASM policy attached to a virtual server.
-- Logout object configured in the policy.
-- System receives a POST request.

Impact:
System goes offline for a few seconds, failover occurs.

Workaround:
Remove logout object configuration from ASM policy.


672040-1 : Access Policy Causing Duplicate iRule Event Execution

Component: Access Policy Manager

Symptoms:
iRule event gets triggered twice in clientless mode when access policy is executed.

Conditions:
This only occurs when using iRule in clientless-mode.

Impact:
HTTP_REQUEST event is logged twice in /var/log/ltm.

See below example:

when HTTP_REQUEST {
  HTTP::header insert {clientless-mode} 1
  set myCount [expr {$myCount + 1}]
  log local0. "Count is $myCount"
}

LTM logs:
-----------

Jul 3 12:29:35 BIG-IP10002-vcmp2 info tmm1[23908]: Rule /Common/test_irule <HTTP_REQUEST>: Count is 1
Jul 3 12:29:36 BIG-IP10002-vcmp2 info tmm1[23908]: Rule /Common/test_irule <HTTP_REQUEST>: Count is 2


When this iRule is used, you will see duplicate HTTP_REQUEST with increased count in logs. If this count is used in further calculation, it gives you incorrect result.


672008-2 : NUL character inserted into syslog message when system time rolls over to exactly 1000000 microseconds

Solution Article: K22122208

Component: Local Traffic Manager

Symptoms:
Remote syslog logging destinations configured for RFC5424 format might receive malformed timestamp values if the log message is sent when clock rolls over to 1,000,000 microseconds exactly. The resulting log message will have a NUL character appended to the microseconds value in the log's timestamp field.

Example:
Correct timestamp: 2003-08-24T05:14:15.000000-07:00
Malformed timestamp: 2003-08-24T05:14:14.100000\00-07:00

Conditions:
-- syslog destination configured for RFC5424 format.
-- Sending log message when clock rolls over to 1,000,000 microseconds.

Impact:
Some syslog collectors may fail to parse the message, resulting in incorrect log entry or warning.

Workaround:
Change syslog destination format to use RFC3164, which does not include microsecond resolution in timestamp fields.


671999-1 : Re-extract the the thales software everytime the installation script is run

Component: Local Traffic Manager

Symptoms:
If Thales has already been installed on the BIG-IP system, installing a new version does not overwrite the existing installed version.

Conditions:
/shared/nfast exists on the BIG-IP system before installing the Thales client software.

Impact:
The old version of the software will be used in the installation operation, instead of the expected new version of the software.

Workaround:
You can use either or both of the following workarounds before running the installation script:

-- Run the uninstallation script.
-- Delete the /shared/nfast folder.


671883-1 : [APM] Ping Access Agent does not correctly handle HTTP request with invalid version

Component: Access Policy Manager

Symptoms:
Ping Access Agent processes HTTP requests based on the assumption that the version in the request will be formatted as follows: HTTP/1.0, HTTP/1.1, etc. If the version is invalid and is specificied without a slash, Ping Access Agent generates a core.

Conditions:
This occurs when both of the following conditions are met:
-- The HTTP request contains an invalid value for the HTTP version field.
-- That provided invalid value does not contain a slash (/) character.

Impact:
Ping Access Agent generates core, which might cause service outage.

Workaround:
* Write an iRule that uses HTTP request events to detect such invalid requests and to generate an error when encountered (e.g.: "ping_access_agent does not process requests with invalid HTTP version values").
* Attach the iRule to the virtual server.

With such an iRule attached to the virtual server, Ping Access Agent will continue to provide the requested service for valid requests.


671880-1 : [APM] Ping Access Agent's internal request processing state needs improvement

Component: Access Policy Manager

Symptoms:
Ping Access Agent maintains the HTTP requests headers in a dictionary. While looking up an HTTP header, it accesses one extra element in the array.

Conditions:
The memory layout of the extra element in the dictionary has the same value as the HTTP header's name.

Impact:
ping_access_agent generates a core, which might cause a service outage.

Workaround:
None.


671714-1 : Empty persistence cookie name inserted from policy can cause TMM to crash

Component: Local Traffic Manager

Symptoms:

Workaround:
Use non-empty peristence cookie name in policy definition.


671627-2 : HTTP responces without body may contain chunked body with empty payload being processed by Portal Access.

Solution Article: K06424790

Component: Access Policy Manager

Symptoms:
Some HTTP responses do not contain any body. For instance, responses with status codes 1xx, 204, or 304 must not include body. Portal Access adds 'Transfer-Encoding: chunked' header and may add chunked body with empty payload to such responses.

Conditions:
HTTP response without body processed by Portal Access

Impact:
Most browsers ignore invalid 'Transfer-Encoding' header and/or body for responses which must not include body at all. And yet, some traffic validators may refuse to pass invalid responses.

Workaround:
Use an iRule to remove 'Transfer-Encoding' header and/or body from HTTP responses with status codes 1xx, 204, and 304.


671579-1 : Macro and macrocall creation issues when policy is in folder

Component: Access Policy Manager

Symptoms:
Attempting creation of macro or macrocall fails when the policy is located in a folder.

Conditions:
-- Access Profile or Per Rq Policy.
-- Location address is similar to the following:
 /partition/foldername/policy

Impact:
Cannot freely use VPE to edit policies.

Workaround:
To work around this:
1. Export Access Profile or Per Rq Policy.
2. Import it to root (/partition/newpolicy) of the partition.
3. Keep it under the root.


671553-1 : iCall scripts may make statistics request before the system is ready

Component: TMOS

Symptoms:

671314-3 : BIG-IP system cores when sending SIP SCTP traffic

Solution Article: K37093335

Component: TMOS

Symptoms:
Virtual servers with an SCTP profile and a SIP message-routing profile may crash the TMM.

Conditions:
This flaw affects virtual servers that pass SCTP traffic, where the SIP message-routing profile has the record-route option enabled.

Impact:
TMM crashes and fails over, disrupting traffic processing. Traffic disrupted while TMM restarts.

Workaround:
Remove the record-route option, or change the traffic to use TCP or UDP instead of SCTP.


671261-1 : MCP does not recognize 'Notify Status to Virtual Address' when using 'Selective' setting of ICMP Echo

Solution Article: K32306231

Component: TMOS

Symptoms:
When selecting 'Notify Status to Virtual Address' on a virtual server, and using the 'Selective' setting of ICMP Echo for a corresponding virtual address, MCP does not recognize that this setting has changed and does not modify the ICMP echo settings of the virtual address accordingly. The previous setting will continue to take effect until another (unrelated) change is made to the virtual address.

Conditions:
The 'Selective' setting of ICMP Echo is used for a virtual address, and the user selects 'Notify Status to Virtual Address' on a virtual server associated with that address.

Impact:
The previous setting will continue to take effect, until an (unrelated) change is made to the virtual address, at which point the new setting will take effect.

Workaround:
After changing the 'Notify Status to Virtual Address' on a virtual server (where 'Selective' setting of ICMP Echo is used for the corresponding virtual address), make another change to the virtual address to cause the new setting to take effect.


671236-1 : BGP local-as command may not work when applied to peer-group

Solution Article: K27343382

Component: TMOS

Symptoms:
Using the BGP level command neighbor <peer-group> local-as <AS> might fail to apply on peers in the peer group.

Conditions:
Applying the BGP local-as command to a peer group.
For instance:
  neighbor <peer-group> local-as <AS>.

Impact:
The command fails to apply, and the actual local AS sent to the peer is that of the BGP process and not the one specified in the command.

Workaround:
Apply the BGP local-as directly to the peer, not the peer-group.


671234-1 : HTTP Authentication agent will hang waiting on unresponsive authentication server.

Component: Access Policy Manager

Symptoms:
Some authentication requests never completes.
APMD responsiveness degrade over time and eventually restart.

Conditions:
The HTTP Authentication server must be alive enough to accept HTTP connections but busy enough to drop requests without closing connections.

Impact:
APMD responsiveness degrades over time, usually weeks, before eventually restarting.

Workaround:
Restarting the HTTP Authentication server usually releases the waiting threads and restores APMD responsiveness.
Using a BIG-IP monitor for the HTTP backend can detect the issue and allow recovery before the need for APMD to restart.


671149-2 : Captive portal login page is not rendered until it is refreshed

Component: Access Policy Manager

Symptoms:
Sometimes Edge Client shows an error page for captive portal-redirected URLs.

Conditions:
Some captive portal pages use cloud-based authentication and network management. Such captive portals rely on several HTTP redirects and/or HTML (auto-refresh). Sometimes Edge Client fails to download the page/content from the redirected URL. In such scenarios, a full browser re-attempts and successfully downloads and displays the page, but Edge Client does not re-attempt and shows an error page.

Impact:
For the locked client, an APM end user has no access to the internet until captive portal authentication is performed and the Network Access (VPN) tunnel is created.

Workaround:
None.


671112-1 : Internal IP Datagroups not matching against some IPv6 network addresses

Component: Local Traffic Manager

670816-4 : HTTP/HTTPS/TCP Monitor response code for 'last fail reason' can include extra characters

Component: Local Traffic Manager

Symptoms:
An HTTP/HTTPS/TCP monitor response code may contain extraneous trailing characters, such as: 'Response Code: 200 (OKxxx)' where the server response code 'OK' is appended with unrelated characters 'xxx', when the server does not include a carriage-return/line-feed after the response status line.

Conditions:
An HTTP/HTTPS/TCP monitor is configured with a receive string, and the server does not include a carriage-return/line-feed in the TCP segments that match the receive string.

Impact:
The monitor status code displays the correct server response code, but with extraneous trailing characters appended. The monitor continues to function and respond to status changes as expected.

Workaround:
Configure HTTP/HTTPS/TCP servers to return a response that includes a carriage-return/line-feed after the response status line and before the receive string.


670804-3 : Hardware syncookies, verified-accept, and OneConnect can result in 'verify_accept' assert in server-side TCP

Workaround:
Disconnect and reconnect.


670520-4 : FastL4 not sending keepalive at proper interval when other side gets response

Component: Local Traffic Manager

Symptoms:
FastL4 not sending keepalive at proper interval when other side gets response. With FastL4, when a response to an LTM-initiated keepalive is received from a device on one side is received, it is forwarded to the other.

It appears that causes a keepalive to not be sent on that other side. The keepalive interval is 20 seconds. If the LTM is scheduled to send a keepalive to the server, but receives a keepalive response on the client side, before it sends the serverside keepalive, the client side keepalive response is forwarded, but the actual keepalive is not sent to the server.

Conditions:
FastL4 and keepalive.

Impact:
Potential for failure as in FastL4: the timeout timer is not updated unless a response is returned. Since the LTM does not send the keepalive, there is not going to be a response for that interval.

Workaround:
None.


670501-6 : ASM policies are either not (fully) created or not (fully) deleted on the HA peer device

Solution Article: K85074430

669025-3 : Exclude the trusted anchor certificate in hash algorithm selection when Forward Proxy forges a certificate

Solution Article: K11425420

Component: Local Traffic Manager

Symptoms:
SSL Forward Proxy signs a forged certificate with a hash algorithm. This selected hash algorithm is the weakest algorithm from the certificates in the server certificate chain except the self-signed certificate.

Some of the intermediate CA certificates in the cert chain use the SHA1 hash algorithm. This kind of intermediate CAs usually is are the BIG-IP system's ca-bundle. BIG-IP receives the cert chain including the intermediate CA and forges the cert with SHA1, which is rejected by some web clients.

Conditions:
-- The BIG-IP system is configured to use SSL Forward Proxy or SSL Intercept.
-- Some intermediate CA in the web server's cert chain is using a weak algorithm like SHA1 to sign certificates.
-- The web client rejects the weak-algorithm-signed certificate.

Impact:
Clients cannot access the web server due to SSL handshake failure.

Workaround:
None.

667577-1 : Access profile 'Restrict to Single Client IP' setting not enforced with DTLS tunnel

Component: Access Policy Manager

Symptoms:
After APM end users establish a session from one client IP address, if they roam and get a different client IP address, the DTLS tunnel will still be able to establish, because the system does not enforce 'Restrict to Single Client IP'.

Conditions:
The client IP used to establish the session is different from the client IP used to establish DTLS tunnel and the 'Restrict to Single Client IP' setting is enabled.

Impact:
The DTLS tunnel will be established, which allows the client to access internal network resources from forbidden subnet.

Workaround:
Disable usage of DTLS tunnel.


667560-2 : FQDN nodes: Pool members can become unmonitored (blue) after monitor configuration is changed

Solution Article: K69205908

Component: Local Traffic Manager

Symptoms:
A pool member configured through an FQDN node and which has multiple associated monitors may become unmonitored (blue) after a monitor rule change to one of its associated monitors. The expected behavior is that the node should remain 'green' if monitoring is successful with the new rule, but the node may become unmonitored (blue) until bigd is restarted.

Conditions:
A pool member is configured through an FQDN node, and has multiple associated monitors, and a monitor rule change is made to one of the associated monitors.

Impact:
The pool member status correctly reflects whether monitoring is successful (green) or the pool member is unmonitored (blue), but the changed monitor rule may not take effect until bigd is restarted.

Workaround:
When making changes to a monitor rule associated with a pool member configured through FQDN, verify the node remains monitored (green or checking), or restart bigd. Alternatively, change monitor rules within the configuration file, and reload the configuration.

Conditions:
The BIG-IP system receives fragmented IPsec encrypted packets that contain fragmented IP packets.

Impact:
Memory leak in the TMM.

Workaround:
None.


667404-1 : Fragmented IP over IPsec tunnels might capture mcp flows and provoke restarts

Solution Article: K77576404

Component: TMOS

Symptoms:
If fragmented IP packets match an IPsec policy, then get forwarded to another tmm for actual processing, the flow lookup might accidentally grab a stale flow_key for another connflow, including internal MCP flows. When that happens, if IPsec does tunnel those flows, internal MCP heartbeats later miss and cause tmm restarts.

Conditions:
-- Packet fragmentation.
-- Packets are serviced by IPsec due to a matching policy for those packets.

Impact:
Tmm restarts. Traffic disrupted while tmm restarts.

Workaround:
You can prevent this using either of the following methods:
-- If you can, arrange that fragmented packets are re-assembled before reaching IPsec policy handling.
-- Modify MTU configuration so fragmentation does not happen.

Note: There is no mitigation when fragmented packets reach IPsec and need forwarding from one tmm to another.


667318-1 : BIG-IP DNS/GTM link graphs fail to display in the GUI.

Workaround:
None.


667278-2 : DSC connections between BIG-IP units may fail to establish

Component: TMOS

Symptoms:
The device service clustering (DSC) connection between two BIG-IP units may fail to establish. One unit will log messages similar to the following example:

-- err mcpd[7912]: 01071af4:3: Inbound CMI connection from IP (192.168.100.1) denied because it came from VLAN (v1542), not from expected VLAN (tmm).

While the unit at the other end of the connection will log messages similar to the following example:

-- notice mcpd[5730]: 01071432:5: CMI peer connection established to 192.168.200.1 port 6699 after 0 retries
May 31 20:58:04 BIG-IP-c-sea notice mcpd[5730]: 0107143c:5: Connection to CMI peer 192.168.200.1 has been removed

Conditions:
This issue occurs when the Self-IP addresses used for Config-Sync by the two BIG-IP units are not in the same IP subnet, and special routing is configured between the BIG-IP units. Examples of special routing include a gateway pool or dynamic routing configurations with multiple routes to the same destination (i.e., ECMP routing).

Impact:
Config-Sync and device discovery operations will fail between affected units.

Workaround:
You can work around this issue by using Self-IP addresses for Config-Sync that are on the same IP subnet or rely on simpler routing to achieve connectivity (i.e., a single route).


667259-1 : Memory Leak in RAM Cache

Solution Article: K15364500

Component: Local Traffic Manager

Symptoms:
A slow increase in the magnitude of the value in the tm_header bucket of the memory_usage_stat table.

Conditions:
This occurs during a refresh of a cached document.

Impact:
A memory leak whose speed is relative to the life time of the documents in the cache, and the number of documents that can be refreshed.

Workaround:
If the document cannot be refreshed, the memory leak won't occur.

A server configuration change or a response iRule that removes the Last-Modified, Expires, and Cache-Control headers will allow the BIG-IP system to cache documents and serve them from cache, but will not attempt to refresh them and thus avoid this leak.

This workaround results in retrieving the whole document from the server when it has expired.


667167-1 : Indirect invocation for History object methods fails using Portal Access

Component: Access Policy Manager

666783-1 : svpn goes into a reconnect loop when another adapter is connected after VPN is connected.

Solution Article: K11974816

Component: Access Policy Manager

Symptoms:
If you connect to VPN, and a previously disconnected network adapter (WiFi/ethernet) gets connected, then svpn goes into a reconnect loop due to routing table conflicts.

Conditions:
- Split tunnel configuration.
- 'Prohibit routing table changes during Network Access' is enabled.

666689-2 : Occasional "profile not found" errors following activate access policy

Component: Access Policy Manager

Symptoms:
Immediately following the activation of a modified access policy it is possible for some profiles to disappear.
It is transient and within a minute or two the profiles are available again.

Conditions:
Clicking "activate access policy" in the GUI or using tmsh to increment snapshot ids will clear the list of profiles and policies and then rebuild those lists. Authentication requests using profiles or policies not yet rebuilt returned the "profile not found" error.

Impact:
Some authentication attempts fail while the lists get rebuilt.
Retrying the authentication a minute or two later succeeds.

Workaround:
Retry the authentication.


666616-1 : Some HTTP iRule commands should always return results as Tcl lists, but do not.

Solution Article: K82565029

Component: Local Traffic Manager

Symptoms:
The HTTP iRule commands behave differently if they return only a single result. They will return a Tcl string rather than a Tcl list containing a string.

Conditions:
One or more of the following HTTP iRule commands are used, and the conditions exist such that a single result is returned:
HTTP::cookie names
HTTP::cookie attribute names
HTTP::header names
HTTP::header values

Impact:
A string is returned rather than a list. This may affect Tcl code that expects the result to be a list, leading to incorrect behavior.

Workaround:
If the result is not a list, this can be detected in a Tcl script, and the result handled as a special case.


666595-1 : Monitor node log fd leak by bigd instances not actively monitoring node

Component: Local Traffic Manager

Symptoms:
Each instance of bigd running on the BIG-IP appliance or on each blade in a VIPRION chassis opens a file descriptor for each node or pool member that has monitor logging enabled. However, only one instance of bigd is actively monitoring each individual node, and actively logging health monitor events to the node log. When LTM health monitors are configured with node logging enabled, the bigd daemon may leak file descriptors for the node logs when the monitor is removed from the LTM node, pool, or pool member configuration.

Note: This problem does not occur if node logging is disabled in the LTM node or pool member configuration ('logging' value set to 'disabled' in the LTM node or pool member configuration) prior to removing the monitor from the LTM node, pool or pool member configuration.

Conditions:
This may occur when the following conditions are met:
1. An LTM health monitor is assigned to an LTM node, pool or pool member with node logging enabled ('logging' value set to 'enabled' in the LTM node or pool member configuration).
2. The LTM health monitor is removed from the LTM node, pool or pool member configuration while logging is still enabled ('monitor' value set to 'none').

Impact:
When this problem occurs, the instance of bigd that is actively monitoring a particular node will close its file descriptor to that node's log file (under /var/log/monitors), but other instances of bigd running on the BIG-IP appliance or on each blade in a VIPRION chassis will leak their file descriptor to the node log.

File descriptors that are opened by the bigd daemon and not closed will count against bigd's internal file descriptor limit. This may result in file descriptor exhaustion and failure of LTM health monitoring.

Workaround:
Disable node logging (set 'logging' value to 'disabled') in the LTM node or pool member configuration prior to removing the monitor from the LTM node, pool, or pool member configuration.

-- DNS load greater than AFM-configured rate limit for IPv6 atomic fragments (default 10 KB).

Impact:
May result in lower than expected DNS load test results.

Workaround:
Use either of the following workarounds:
-- Disable AFM.
-- Increase detection limit for IPv6 atomic fragments under AFM.

Note: For AFM HW DoS protection, the host and vCMP guest must be the same version, disable hardware DoS checking on the vCMP guest to prevent this issue. To do so, set sys db dos.forceswdos to 'true'.

Failed to allocate memory for size 260 at clone_message:952.

The memory size indicated in the message may be incorrect.

Conditions:
MCP runs out of memory while attempting an allocation.

Impact:
Misleading logs that make it more difficult to troubleshoot mcpd memory issues.

Workaround:
None.


663821-2 : SNAT Stats may not include port FTP traffic

Solution Article: K41344010

Component: Local Traffic Manager

Symptoms:

Workaround:
None.


663770 : AFM rules are bypassed / ignored when traffic is internally forwarded to a redirected virtual server

Solution Article: K04025134

Component: Advanced Firewall Manager

Symptoms:
AFM rules are bypassed / not evaluated on the 'redirected' virtual server when the traffic is internally forwarded to that virtual server.

This is a regression from 12.1.x behavior.

Conditions:
Incoming traffic matches a virtual server and then gets internally redirected to another virtual server either via an iRule or a LTM local traffic policy.

Impact:
This has the effect of potentially negating firewall protections for the traffic that is being redirected to a different virtual server (application) if that virtual server has an AFM policy enabled on it.

Workaround:
There is no workaround at this time.


663748-1 : tmm might crash if AFM DoS address-list whitelist is present in sPVA HW platforms

Component: Advanced Firewall Manager

Symptoms:
At bootup, there is a possibility of tmm crashing while coming up when the configuration contains an AFM address-list whitelist on an sPVA hardware platform.

Conditions:
Configuration contains AFM address-list whitelist on an sPVA HW platform, and the race condition happens in which tmm and mcpd start interacting before the hardware HSB is ready.

Impact:
tmm will crash and restart. Traffic disrupted while tmm restarts.

Workaround:
Remove the AFM address-list whitelist, and then configure it once the system is up.


663580-2 : logrotate does not automatically run when /var/log reaches 90% usage

Component: TMOS

Symptoms:
The alertd daemon does not run logrotate when the diskmonitor utility detects that /var/log has less than 10% free space.

Conditions:
/var/log has less than 10% free space.

Impact:
The /var/log filesystem might become completely full, preventing new log messages from being written.

Note: K8865: Overview of the diskmonitor utility (https://support.f5.com/csp/article/K8865) provides a desription for expected behavior.


663531-2 : TMM crashes when PPTP finds a non-ALG flow when checking for an existing tunnel

Component: Carrier-Grade NAT

Symptoms:
TMM crashes when PPTP finds a matching non-PPTP-GRE flow when checking for an existing tunnel.

Conditions:
PPTP-ALG and CGNAT on a BIG-IP system when a GRE tunnel matches a PPTP-GRE flow

Impact:
Traffic disrupted while tmm restarts.

Workaround:
Possible mitigation by not using a forwarding virtual for non-PPTP GRE traffic.


663521-3 : Intermittent dropping of multicast packets on certain BIG-IP platforms

Component: TMOS

Symptoms:
The switch device on the VIPRION B2250 and B4300 blades and the BIG-IP 10x00, i10x00, i7x00 and i5x00 platforms might drop multicast packets under certain high traffic conditions.

Conditions:
-- Certain high-traffic conditions.
-- Running on the specified blades/platforms.

Note: These dropped packets are counted under the 'drop_out' column from 'show net interface all-properties'.

Impact:
Dropped multicast packets, possibly impacting multicast protocols.

Workaround:
None.


663506-2 : apmd crash during ldap cache initialization

Solution Article: K30533350

Component: Access Policy Manager

Symptoms:
apmd crashes.

Conditions:
- LDAP module is in use in an access policy,
- APM end-users are logging in, while administrator modifies AAA LDAP Server or LDAP Agent,
- Cache update takes a while (too many groups in domain and/or slow network).

Impact:
BIG-IP cannot process user logon request, until apmd is restarted and LDAP cache is updated

Workaround:
The best practice is to update policy/AAA LDAP Server when BIG-IP is not under load. Then make one logon manually. apmd updates caches on first APM end-user's logon. Once caches update, all the further logons should happen much faster and should not cause any problems


663492-1 : Reconfigured istat may stop being recomputed

Component: TMOS

Symptoms:
When an istat is configured and used, it is possible to remove and then re-add the istat such that it does not get properly updated after it is re-added.

Conditions:

Condition for this issue to happen is unknoown, Possible conditions include vrious configuration changes to apmd; or large number of concurrent sessions.

Impact:
User cannot see any session-related apmd logs, from any destinations including local syslog, local-db, remote syslog.

Workaround:
1. Try to re-configure APM logging, i.e. change the association of log setting and access profile, then change it back
2. As a final resort, restart apmd.


663366-4 : SEGV fault can occur during tmm 'panic' on i4x00 and i2x00 platforms.

Component: TMOS

Symptoms:
On the i4x00 and i2x00 platforms, TMM can encounter a second SEGV fault while crashing from an initial 'panic'.

Conditions:
-- i4x00 and i2x00 platforms.
-- TMM encounters a second SEGV fault while crashing from an initial 'panic'.

Impact:
TMM is crashing due to a 'panic'. No additional impact, as traffic is already disrupted while tmm restarts.

Workaround:
None.


663333-2 : TMM may core in PBA mode id LSN pool is under provisioned or the utilization is high

Component: Carrier-Grade NAT

Symptoms:
TMM may core while trying to allocate a new block

Conditions:

Impact:
Traffic disrupted while tmm restarts.


663326-1 : Thales HSM: "fipskey.nethsm --export" fails to make stub keys

Component: Local Traffic Manager

Symptoms:
When using "fipskey.nethsm --export -i /shared/tmp/testkey.pem -o thaleskey" to export a key file from BIG-IP and import into HSM, the HSM fails to generate the stub key at /config/ssl/ssl.key/ on the BIG-IP system.

Conditions:
-- Thales HSM is installed.
-- Running 'fipskey.nethsm --export' to export a key file from BIG-IP and import it to the Thales HSM.

Impact:
Even the key has been stored in HSM, the BIG-IP is still unable to use it because of its lacking stub key to be configured on the BIG-IP system.

Workaround:
This can be worked around by directly using the Thales command, for example:

[root@localhost:Active:Standalone] config # generatekey --import pkcs11 certreq=yes
type: Key type? (DES3, RSA, DES2) [RSA] >
pemreadfile: PEM file containing RSA key? []
> /shared/tmp/testkey.pem

Workaround:
Before upgrading, add the following line to the named.conf options:
masterfile-format text;


663181-1 : VDI plugin-initiated connections may select inappropriate SNAT address

Component: Local Traffic Manager

Symptoms:
When the VDI plugin makes outgoing connections, the source address is selected from a SNAT pool. Should the connection pass through another matching virtual server before reaching the external network, the selected SNAT address may be inappropriate for the egress VLAN.

Conditions:
-- APM configuration.
-- VDI functionality enabled.
-- Additional virtual server matching the VDI-initiated connections.

Impact:
Return traffic from destination may not be able to return to the BIG-IP system, thus breaking the VDI functionality.

663073-3 : GSLB Pool member Manage page combo box has an issue that can cause the wrong pool member to be removed from the available list when adding a member to the selected list.

Component: Global Traffic Manager (DNS)

Symptoms:
GSLB Pool member Manage page combo box has an issue that can cause the wrong pool member to be removed from the available list when adding a member to the selected list.

Conditions:
When adding a pool member via the combo box, if you click the arrow to expand the dropdown list and select a member by clicking on it, that member name is added to the text box.

If you then mouse over other members in the dropdown list, and then click the Add button, the system adds the selected member to the list, but also removes the wrong member from the combo box: more specifically, it removes the member that was last highlighted by the mouse over.

Impact:
Available pool members might be potentially lost from the combo box until a page reload.

Note: The pool members are not gone from the system; they are still present, just not displayed.

Workaround:
Either use TMSH or place the mouse cursor away from the combo box, and use the text box to narrow down the content in the dropdown list. Then use the arrow keys and the Enter key to select the desired pool member.


663063-1 : Disabling pool member used in busy HSL TCP destination can result service disruption.

Component: TMOS

Symptoms:
Manually disabling an otherwise available pool member from a pool used as HSL TCP destination can result in tmm crash and service disruption.

This is more likely to occur when HSL destination is using 'balanced' distribution.

Conditions:
-- Busy HSL destination configured with TCP protocol, balanced distribution, and using pool.
-- Manually disabling a pool member.

Impact:
Service disruption while tmm recovers. HA fail-over event. Traffic disrupted while tmm restarts.

Workaround:
You can avoid the issue in either of these ways:
-- Do not manually disable busy pool members that can still respond to TCP handshake.
-- Disable the service on the pool member first.


662913-1 : GUI LTM Virtual Server page cannot open. Virtual Server cannot be created or updated.

Solution Article: K17213048

Component: TMOS

Symptoms:
In the GUI when a user tries to create or edit a Virtual Server, the page is blank. There is an error that prevents the page from loading properly.

Conditions:
When provisioning BIG-IP with APM license.

Impact:
Users cannot access the Virtual Server page from the GUI.

Workaround:
User can create and edit the Virtual Server using TMSH command line tool.


662911-3 : SASP monitor uses same UID for all vCMP guests in a chassis or appliance

Solution Article: K93119070

Component: Local Traffic Manager

Symptoms:
The SASP GWM monitor generates the LB UID from the chassis serial number of the platform on which BIG-IP is running. All vCMP guests running on the platform attempt to use the same UID.

The LB UID used to connect to the Server/Application State Protocol (SASP) Group Workload Manager (GWM) is required to be unique for each client connecting to the GWM.

As a result, only one vCMP guest running on each BIG-IP appliance or VIPRION chassis is able to successfully use the SASP monitor.
- The SASP monitor running on the first vCMP guest can successfully connect to the SASP GWM.
- Subsequent SASP monitor instances running on other vCMP guests will fail to connect to the SASP GWM.

Conditions:
This occurs when multiple vCMP guests are running on a single BIG-IP appliance or VIPRION chassis, each using a SASP monitor connecting to the same SASP GWM to monitor pool member availability.

Impact:
The SASP monitor is unable to monitor pool member availability on more than one vCMP guest running on a single BIG-IP appliance or VIPRION chassis.

Workaround:
None.


662881-1 : L7 mirrored packets from standby to active might cause tmm core when it goes active.

Solution Article: K10443875

Component: Local Traffic Manager

Symptoms:
L7 mirrored packets from standby to active might cause tmm core when it goes active.

Conditions:
-- Spurious ACK sent to the standby unit that is mirrored over to the active unit for processing.
-- Matching connection on the active has not been fully initialized.

Impact:
tmm crashes. Traffic disrupted while tmm restarts.

Workaround:
None.


662816-1 : Monitor node log fd leak for certain monitor types

Solution Article: K61902543

Component: Local Traffic Manager

Symptoms:
When certain types of LTM health monitors are configured with node logging enabled, the bigd daemon may leak file descriptors for the node logs when the monitor is removed from the LTM node, pool or pool member configuration.

Conditions:
This may occur when:
1. One of the below-listed LTM health monitor types is assigned to an LTM node, pool, or pool member with node logging enabled ('logging' value set to 'enabled' in the LTM node or pool member configuration).
2. The LTM health monitor is removed from the LTM node, pool, or pool member configuration while logging is still enabled ('monitor' value set to 'none').

Affected LTM health monitor types include:
diameter, external, firepass, ftp, gateway_icmp, icmp, imap, ldap, module_score, mssql, mysql, nntp, oracle, pop3, postgresql, radius, radius_accounting, real_server, rpc, sasp, scripted, sip, smb, smtp, snmp_dca, snmp_dca_base, soap, virtual_location, wap, wmi.

This problem does not occur if node logging is disabled in the LTM node or pool member configuration ('logging' value set to 'disabled' in the LTM node or pool member configuration) prior to removing the monitor from the LTM node, pool, or pool member configuration.

The following LTM health monitor types are not affected:
dns, http, https, inband, mqtt, tcp, tcp_echo, tcp_half_open

Impact:
When this problem occurs, each instance of bigd running on the BIG-IP appliance or on each blade in a VIPRION chassis leaks one file descriptor for each node or pool member with monitor logging enabled.

File descriptors that are opened by the bigd daemon and not closed count against bigd's internal file descriptor limit. This can result in file descriptor exhaustion and failure of LTM health monitoring.

Workaround:
Disable node logging (set 'logging' value to 'disabled') in the LTM node or pool member configuration prior to removing the monitor from the LTM node, pool, or pool member configuration.


662372-2 : Uploading a new device certificate file via the GUI might not update the device certificate

Solution Article: K41250179

Component: TMOS

Symptoms:
After uploading a new device certificate via the 'Upload File' option in the GUI, the device certificate remains unchanged.

Conditions:
-- Upload a new device certificate file via the GUI.
-- There is already a file called /tmp/server.crt.

Impact:
The device certificate is not updated and no error is shown.

Workaround:
Use the 'Paste Text' option to import the certificate.


662281-1 : Inconsistencies in Automatic sync ASM Device Group

Component: Application Security Manager

Symptoms:
Some ASM calls are not propagated correctly across an automatic sync device group.

This can cause any of the following depending on the change:
A) Superfluous full syncs
B) Updating the wrong element on the remote devices
C) Missing changes on the remote devices

Conditions:
Automatic Sync is configured for a Device Group with ASM enabled.

Impact:
Any of the following depending on the change:
A) Superfluous full syncs
B) Updating the wrong element on the remote devices
C) Missing changes on the remote devices

Workaround:
Disable automatic sync on the device group, and periodically push changes manually.

Component: Local Traffic Manager

Symptoms:
Using Node.js package manager (NPM) to install a large Node.js package in the TMUI results in truncated contents in the workspace.

Conditions:
Installing large Node.js packages using the TMUI.

Impact:
The workspace contents will be truncated. Some of the package contents will be missing, or boilerplate F5 elements (f5-nodejs, package.json, etc.) will not be shown.

Workaround:
None.

Note: TMSH recognizes the entire file structure of node_modules (e.g., package.json and module folders of f5-nodejs and async), but TMUI does not.


661881-1 : Memory and performance issues when using certain ASN.1 decoding formats in iRules

Solution Article: K00030614

Component: Local Traffic Manager

Symptoms:
Memory and performance issues when using calls to ASN1::decode with "a" or "B" characters in the format string. This occurs because these calls do not correctly free memory allocated by those functions.

Conditions:
iRules that contain calls to ASN1::decode with "a" or "B" characters in the format string.

Impact:
Memory leak, degraded performance, potential eventual out-of-memory crash.

Workaround:
None.

Note: Because of the memory leak associated with this issue, using calls to ASN1::decode with "a" or "B" characters in the format string should be avoided.


661716 : TMM core when session ticket and OCSP Stapling is enabled on the clientSSL profile

Solution Article: K05655212

Component: Local Traffic Manager

Symptoms:
TMM core when session ticket and OCSP Stapling is enabled on the clientSSL profile.

Conditions:

660868-1 : Resets after adding URL Branching item

Component: Access Policy Manager

Symptoms:
Clients receiving resets, and these error logs in /var/log/apm:
Apr 25 14:23:12 ip-10-1-1-4 err tmm[12329]: 01870029:3: /Common/Allow_Access:Common:780e1b9f: [C] 10.1.10.9:57991 -> 10.1.10.102:443:ERR_NOT_FOUND: failed to find next policy item

Conditions:
A URL Branching item was added to the per-request policy. The item template for URL Branching contains single-quotes in the expression, which are considered invalid by the TCL interpreter.

Impact:
The invalid expression causes a non-recoverable failure in the control plane of TMM. Changing the expression has no effect.

Workaround:
Because of the non-recoverable failure caused by the invalid expression, there are only two workarounds:
1) Do not use the URL Branching template. Equivalent functionality is achieved by adding an empty item and using the expression builder. The templates in the expression builder are correct.
2) If a URL Branching template was already used, fix the expression by replacing all single-quotes with double-quotes. Then `bigstart restart tmm` to reset the affected part of the control plane.


660833-1 : merged repeatedly cores due to unused istats-trigger object

Component: TMOS

Symptoms:
If any of the elements of the istats-trigger configuration are not defined, this issue occurs. For example, all the elements defined in the key of the istats-trigger definition must be defined before the trigger is created.

Conditions:

Impact:
merged restarts.

Workaround:
None.


660760-2 : DNS graphs fail to display in the GUI

Component: TMOS

Symptoms:
Can no longer view the DNS graphs in the GUI after upgrading from an earlier release. The system reports the following error in the GUI when visiting GUI Statistic :: Performance :: DNS: Error trying to access the database.

Conditions:
This occurs when the BIG-IP system is licensed for the GTM module (mod_gtm) instead of the DNS module (mod_dnsgtm). This might occur in the case where the system is upgraded from an earlier release such as v10.2.4 (where the module was GTM) to a later release such as v12.1.1 (where the module is DNS).

Impact:
Accessing the DNS graphs in the GUI fails.

Workaround:
None.


660711-2 : MCPd might crash when user trying to import a access policy

Solution Article: K05265457

Component: Access Policy Manager

Symptoms:
MCPd restarts during importing an access policy; other daemon might also restart because of MCPd restart.

Conditions:
This occurs when an access policy uses the same agent more than once.
Importing that access policy causes MCPd to crash.

this can happen when you don’t use GUI/VPE to manage access policy but directly modify the config file in exported access policy.

Only use the GUI/VPE to manage access policies.

You should not modify the config file for an exported access policy.

Impact:
MCPd and some other daemons restart. GUI unresponsive for a while.

Workaround:
Only use the GUI/VPE to manage access policies.

You should not modify the config file for an exported access policy.


660654 : 'epsec refresh' works incorrectly if install package is deleted

Component: Access Policy Manager

None.


660327-1 : Config load fails when attempting to load a config that was saved from before 12.1.0 on a system that was already upgraded.

Component: Application Security Manager

Symptoms:
Config load fails when attempting to load a config that was saved from before 12.1.0 on a system that was already upgraded.

This happens only if before the upgrade, there was an ASM logging profile which had both remote logging and local logging enabled on it.

In the case of a single logging profile with local-plus-remote ASM enabled on it, upon an upgrade, the logging profile is split into two profiles. One has the '_local' extension added to it. Another attempt to load the config of the pre-upgrade system will fail. This only happens when using 'load sys config' or 'load sys config file', and does not happen when using 'load sys ucs'.

Upon failure, the following error is seen on the terminal:
01070710:3: Cannot update_indexes/checkpoint DB object, class:fw_log_profile status:13 - EdbCfgObj.cpp, line 127
Unexpected Error: Loading configuration process failed.

And in /var/log/ltm:
err mcpd[6618]: 01070710:3: Database error (13), Cannot update_indexes/checkpoint DB object, class:fw_log_profile status:13 - EdbCfgObj.cpp, line 127.

Conditions:
-- Using a configuration that contains a Log Profile with ASM enabled and both Remote Log and Local Log enabled.
-- Upgrade to 12.1.2 or later (Use roll-forward upgrade, or instead use clean install and afterwards load the saved config file).

Impact:
Config load fails. Upgrade fails.

Workaround:
Use one of the following Workarounds:
1.
Save the new configuration before editing and re-loading, using the following commands:
tmsh save sys config partitions all
tmsh load sys config partitions all

(Note: Saving the UCS also saves the configuration.)

2.
Instead of loading the full configuration directly, first load the base and then load the full configuration:
tmsh -c 'load sys config partitions all base; load sys config partitions all'


660326-1 : Upgrade fails when a websecurity profile assigned to virtual server but ASM is not provisioned.

Solution Article: K91072177

Symptoms:
Upgrade fails when a websecurity profile assigned to virtual server but ASM is not provisioned.

Conditions:
-- Websecurity profile assigned to a virtual server.
-- ASM not provisioned.
-- Upgrade to v12.1.0 or later.

Impact:
Upgrade fails.

Note: Although this is an invalid configuration, upgrade should not fail.

Workaround:
There are two workarounds.
-- Provision ASM.
-- Remove all websecurity profiles (and LTM policies that control ASM) from all virtual servers

Note: The first workaround must be done before the update. The second can be done before the upgrade, or by editing the config files and re-loading config (first base, then all) using the following command:

tmsh -c 'load sys config partitions all base; load sys config partitions all'

658636-3 : When creating LTM or DNS monitors through batch/transaction mode newlines are improperly escaped.

Solution Article: K51355172

Component: TMOS

Symptoms:
- LTM/DNS monitors created via tmsh batch/transactions improperly escape newline characters.
- Expected escaping: \r\n
- Actual escaping: \\r\\n
- Impact: The URI sent is not correct,

Conditions:
When creating LTM or DNS monitors through batch/transaction mode when strings contain newline characters. For example, using the following commands to batch-create:

create gtm monitor http one_test_mon { send "GET / HTTP/1.0\r\nHost: abc.example.com\r\nUser-Agent: slb-healthcheck\r\nConnection: Close\r\n\r\n" recv "200"}
submit cli transaction
list gtm monitor http one_test_mon

The system creates the following monitor:

gtm monitor http one_test_mon {
    defaults-from http
    destination *:*
    interval 30
    probe-timeout 5
    recv 200
    send "GET / HTTP/1.0\\r\\nHost: abc.example.com\\r\\nUser-Agent: slb-healthcheck\\r\\nConnection: Close\\r\\n\\r\\n"

Impact:
Cannot use batch/transaction mode in TMSH to create LTM or DNS monitors. Cannot use LTM or DNS monitors created using batch/transaction mode in tmsh.

Conditions:
-- JavaScript code sets/changes long cookie value or uses long cookie name;
-- Chrome or MS Edge browser is used.

Impact:
tmm crashes. Traffic disrupted while tmm restarts.

Workaround:
Use an iRule to remove 'Origin' header from any request to '/private/fm/volatile.html'.

Note: This iRule has to enable events for internal requests using 'ACCESS::restrict_irule_events enable' command.


658343-3 : AVR tcp-analytics: per-host RTT average may show incorrect values

Solution Article: K33043439

Component: Application Visibility and Reporting

Symptoms:
When viewing the Statistics :: Analytics :: TCP :: RTT, then selecting (in the table below the graph), View By: "Remote Host IP Address", the values presented RTT Avg (ms) may be incorrect (they could even be larger than the RTT Max column).

As values are aggregated through the data tables, the reported rtt average value becomes larger and larger.

Conditions:
AVR is provisioned, and a tcp-analytics profile is attached to a virtual server.

Impact:
The values reported in the RTT Avg column when viewing by Remote Host IP Address may be incorrect.

Workaround:
None.

Component: Policy Enforcement Manager

Symptoms:
If intra-chassis failover is triggered in a loaded chassis, the tmm crashes in some cases of GY reporting

Conditions:
-- Failover is triggered,
-- The daglib hash redistributes the subscriber DATA to different slots.
-- Existing flows continue on the slots that were allocated using the old hash of daglib.

Note: This is a rarely encountered issue that occurred in a setup with 8 slots and 750 thousand subscribers.

Impact:
Slot reboots. May trigger more hash rearrangement. Traffic disrupted while tmm restarts.

Workaround:
None.

Component: Local Traffic Manager

Symptoms:
In some cases, a mirrored FastL4 virtual server may fail to forward the SYN on the server-side after receiving the context-ack from the peer. Note: This is a connection-failure through the active system, not simply a failure to mirror to the peer.

Symptoms include:
-- TCP connection failures.
-- Possibly other packets lost.

Conditions:
-- FastL4 virtual server.
-- Mirroring is enabled.
-- Certain traffic interleaving might be necessary for this intermittent problem to occur.

Impact:
FastL4 mirroring does not always forward SYN to server after receiving context ACK. Connections fail.

Workaround:
Set the tm.fastl4_ack_mirror dv variable using the following command: tmsh modify sys db tm.fastl4_ack_mirror value disable.


658148-4 : TMM core after intra-chassis failover for some instances of subscriber creation

           }
           elseif { ([IP::local_addr] equals "1.1.1.2") } {

                     ASM::enable /Common/http_asm_policy_2
                     log local0. "2 access"

           }
}

Impact:
Getting dropped request.

Workaround:
None.


657883-1 : tmm cache resolver should not cache response with TTL=0

Solution Article: K34442339

Component: Local Traffic Manager

Symptoms:
tmm cache resolver caches responses with TTL=0, and it shouldn't.

Conditions:
TTL is set to 0 on the BIG-IP DNS system, so TMM will see TTL=0 from the DNS answer.

Impact:
tmm cache resolver caches responses with TTL=0.

Workaround:
None.


657858-3 : TMM can restart when VLAN keyed connections are disabled.

Solution Article: K85425460

Component: Local Traffic Manager

Symptoms:
TMM may restart intermittently when VLAN-keyed connections are disabled.

Conditions:
VLAN-keyed connections are disabled. Several types of traffic can cause this, including FTP traffic and multicast traffic.

Impact:
Traffic disrupted while TMM restarts.

Workaround:
None.


657834-1 : Extraneous OSPF retransmissions and ospfTxRetransmit traps can be sent

Component: TMOS

Symptoms:
When using OSPF with high load and network recalculation there is a possibility of a race condition that can lead to additional OSPF retransmissions being sent out. This might also cause SNMP traps to be sent, if configured on the system.

Conditions:
-- OSPF routing protocol configured.
-- System configured to send SNMP traps.
-- OSPF instability/networking flaps.

Note: The greater the number of routes flapping, the more likely to see the condition.

Impact:
There is no impact on the OSPF processing itself. The additional traffic does not cause failing adjacencies or loss of routing information.

However, this might cause many additional OSPF related traps to be sent, which might cause additional load on the external network monitoring system.

Workaround:
While this does not have a direct workaround, you may want to investigate the cause of the network/OSPF instability that causes the additional retransmissions.


657727-1 : Running tcpdump from TMSH cannot capture the local "tmm" interface

Solution Article: K39694060

Component: TMOS

Symptoms:
Cannot run tcpdump against the "tmm" interface. System posts errors similar to the following:
tcpdump: pcap_loop: Device /Common/tmm not found
tcpdump: ioctl: No such device

This occurs because the 'tmm0' interface was renamed to 'tmm' beginning in v12.1.0, but the libbigpacket conditional logic to handle "special device names" still references 'tmm0'.

Conditions:
-- When running tmsh, an environment variable ("TMOS_PATH") is set.
-- The user logs in to the CLI with a default shell of tmsh (either as configured, or with a role assigned via remote-roles), or tries to run tcpdump via tmsh.

Impact:
Cannot run tcpdump on the 'tmm' internal interface.

Workaround:
Unset the 'TMOS_PATH' environment variable before running tcpdump.


657713-1 : Gateway pool action may trigger the Traffic Management Microkernel (TMM) to produce a core file and restart.

Solution Article: K05052273

Component: Local Traffic Manager

Symptoms:
As a result of this issue, you may encounter one or more of the following symptoms:

-- TMM generates a core file in the /shared/core directory.
-- Your BIG-IP system logs a SIGFPE to the /var/log/tmm file at the same time TMM produces a core file and restarts.
-- In one of the /var/log/tmm log files, you may observe error messages similar to the following example:
es/hudfilter/hudfilter.c:1063: Assertion "valid node" failed.notice panic: ../modul

DOWN_L4_4 notice ** SIGFPE **

Conditions:
This issue occurs when all of the following conditions are met:

-- Your BIG-IP system is configured to route traffic using a gateway pool.
-- The gateway pool is configured with Action On Service Down = Reject.
-- The pool monitor marks all members of the gateway pool as unavailable.
-- A connection is rejected by the gateway pool.

Impact:
The BIG-IP system temporarily fails to process traffic while the TMM process restarts. If the BIG-IP system is configured for high availability (HA), the system fails over to a peer system.

Workaround:
Set service-down-action to none or reselect.


657708-1 : Packet Tester is still available in the GUI when AFM is not provisioned

Solution Article: K50308190

Impact:
The packet tester is available to use when it should not be.

Workaround:
None.


657632-5 : Rarely if a subscriber delete is performed following HA switchover, tmm may crash

Component: Policy Enforcement Manager

Symptoms:
If a subscriber delete is performed following a HA switchover, tmm may coredump. The probability of this scenario is rare, where a subscriber may have been freed during switchover and a subsequent forced delete command quickly follows.

Conditions:
-- A subscriber delete command followed by a HA switchover.
-- During the switchover, the subscriber was freed.

Impact:
Traffic disrupted while tmm restarts.

Workaround:
None.


657626-1 : User with role 'Manager' cannot delete/publish LTM policy.

Component: Local Traffic Manager

Symptoms:

Impact:
UMU memory goes up.

Workaround:
-- Decrease the max concurrent long requests.
-- Decrease the size for the long requests buffer size.
-- Make sure the ICAP server is up and running and responding quickly (the issue will be more visible when the ICAP server is lagging).


657502-1 : JS error when leaving page opened for several minutes

Component: Fraud Protection Services

Symptoms:
Google Chrome delays JS execution when the tab is not active.
Therefore anti-debug module acts as if someone is trying to debug JS code.

Conditions:
-- JS runs in hidden tab in Google Chrome.
-- Anti-debug functionality is active.
-- Page is left open for several minutes.

Impact:
Errors in console and JS logic is incorrectly executed.

Component: TMOS

Symptoms:
Setting MGMT GUI Port to 443 on Single Nic not honored on reboot.

Conditions:
Setting MGMT GUI Port to 443 on Single Nic.

Impact:
The 443 value is not saved after reboot.

Workaround:
Reconfigure port after each reboot using the following command: modify sys httpd ssl-port 443.


656811-7 : Memory usage with MBLB SIP ingress buffer on standby

Component: Service Provider

Symptoms:
Memory usage increases to high levels when the ingress-max profile setting is set to a large value.

Conditions:
Incoming SIP messages are mirrored to standby, then the flow is aborted on active.

Impact:
Degraded performance. With the built-in MBLB profile allocations will go up to 50 and stay there until the 'while' is killed on the client and the flow is allowed to expire. With a non-default MBLB profile, allocations will go as high as the ingress-max setting.

Workaround:
- Make sure there is at least one available pool member.
- Use default MBLB profile, or at least ingress-max set close to the default (50).


656807-1 : iRule DNS::ttl does not allow 0 (zero)

Component: Global Traffic Manager (DNS)

Symptoms:
DNS::rr cannot set ttl to 0. The system returns the following message: error: [internal error "unexpected return code"][DNS::ttl $rr 0].

Conditions:
-- Using iRule DNS::ttl.
-- Trying to set ttl to 0.

Impact:
DNS::rr cannot set ttl to 0, the resolver cache can't be disabled, and the system returns an error: error: [internal error "unexpected return code"][DNS::ttl $rr 0]

Workaround:
None.


655807-1 : With QoS LB, packet rate score is calculated incorrectly and dominates the QoS score

Solution Article: K40341291

Component: Global Traffic Manager (DNS)

Symptoms:
When choosing QoS Load balance, packet rate is dominating the score.

Conditions:
QoS load balance.

Impact:
Load balance decision is mostly impacted by packet rate.

Workaround:
None.


655793-2 : SSL persistence parsing issues due to SSL / TCP boundary mismatch

Component: Local Traffic Manager

Symptoms:
When the SSL client or server system is set up to send SSL messages whose boundaries do not align with underlying TCP boundaries, the parser fails when SSL persistence is enabled.

So, any SSL record spanning over multiple TCP segments (in this case it's ServerHello, Certificate, and ServerHelloDone) triggers the issue with the SSID error RST cause.

This can also result from a message size exceeding the maximum configured size (default is 32K).

Conditions:
[1] SSL persistence is enabled.
[2a] SSL message boundary does not align with underlying TCP segment boundary. One example of boundary mismatch is when the TCP MTU size is changed to a lower value (around 1200 bytes). Even then there may be specific values for which the boundaries match and parsing succeeds.
[2b] The message size is greater than the maximum configured size (default 32k).

Impact:
When the parsing fails, the SSL client or server hangs and times out. In other words, SSL traffic is affected.

The SSL parsing should succeed regardless of a match or mismatch between SSL message boundary and TCP segment boundary.

Workaround:
Disable SSL persistence.


655767-4 : MCPD does not prevent deleting an iRule that contains in-use procedures

Component: Local Traffic Manager

Symptoms:
If an iRule that is attached to a virtual server makes a procedure call in a different iRule, it is possible to delete the different iRule with no error.

MCPD contains validation that should prevent a user from deleting an iRule that is currently in use by a virtual server, e.g.:

    01070265:3: The rule (/Common/rule_uses_procs) cannot be deleted because it is in use by a virtual server (/Common/vs_http).

However, if an iRule attached to a virtual server makes a procedure call in a different iRule, it is possible to delete the different iRule with no error. This results in a configuration that will subsequently fail to load (during a config load, MCPD validation will catch this), or will fail if a full configuration sync is performed.

Conditions:
Must be using iRules that call into other iRules.

Impact:
System gets into a state where traffic may fail unexpectedly, and subsequent reboots, configuration loads, upgrades, or configuration sync operations will fail.

Workaround:
None. Use caution when deleting iRules, especially iRules that call into other iRules.


655724-4 : MSRDP persistence does not work across route domains.

Solution Article: K15695

Component: Local Traffic Manager

Symptoms:
MSRDP persistence doesn't work with non-default route domains.

Conditions:
Configure a virtual server with a MSRDP persistence profile and a pool using a non-default route domain.

Impact:
MSRDP persistence does not work.

Workaround:
Implement MSRDP persistence using iRules.


655671-2 : Polling time waiting for I2C bus transactions in the bcm56xxd daemon needs to be reduced

Component: TMOS

Symptoms:
On platforms that run the bcm56xxd daemon, the polling time that the system waits for I2C bus transactions to complete runs too long. On systems with I2C bus issues, this can lead to bcm56xxd core files, because the bcm56xxd daemon doesn't reset the watchdog so the watchdog timer kills the process.

Conditions:
This is an issue only when there is a stuck I2C bus, which occurs rarely.

Impact:
bcm56xxd process may core and restart. That typically resets the I2C bus, which resolves any issues.

Workaround:
None. Typically, the issue resolves itself.


655649-1 : BGP last update timer incorrectly resets to 0

Component: TMOS

Symptoms:
In ZebOS, every time the scan timer resets it also incorrectly resets the BGP last update timer as shown under the imish command 'sh ip route'.

Output from 'sh ip route':

4054fdc0-3e51-4079-b52f-4a3b058a3f93#sh ip ro
...
B 10.30.0.0/16 [20/0] via 10.10.1.2, eno33554952, 00:00:32
                    [20/0] via 10.10.1.6, eno33554952, 00:00:32
...
4054fdc0-3e51-4079-b52f-4a3b058a3f93#sh ip ro

B 10.30.0.0/16 [20/0] via 10.10.1.2, eno33554952, 00:00:33
                    [20/0] via 10.10.1.6, eno33554952, 00:00:33
...
4054fdc0-3e51-4079-b52f-4a3b058a3f93#sh ip ro
...
B 10.30.0.0/16 [20/0] via 10.10.1.2, eno33554952, 00:00:00 <<<< shouldn't reset
                    [20/0] via 10.10.1.6, eno33554952, 00:00:00

Conditions:
Once ZebOS has learned a route from a BGP peer the route will show up under 'sh ip route' and the BGP last update timer will incorrectly reset.

Impact:
None. This is cosmetic.

Workaround:
None.


655628-2 : TCP analytics does not release resources under specific sequence of packets

Component: Local Traffic Manager

Symptoms:
TCP analytics does not release memory when a specific sequence of packets is observed, and memory usage increases as more such flows occur.

Conditions:
-- A TCP analytics profile is configured to collect clientside/serverside analytics data.
-- AVR is provisioned.
-- FastL4 and HTTP profiles are configured.
-- A specific sequence of packets (on the serverside) occurs.

Impact:
Main memory occupied by TCP analytics is not released which might lead to memory exhaustion on the BIG-IP system.

Workaround:
Turn off collecting TCP analytics data for the virtual server.


655506 : Guest configurations with mergeable buffers disabled are not supported.

Component: TMOS

Symptoms:
Guest configurations with mergeable buffers disabled are not supported.

Conditions:
Guest configuration explicitly disables mergeable buffers:
<host mrg_rxbuf='off'/>.

Impact:
tmm core. Traffic disrupted while tmm restarts. When mergeable buffers are disabled, the 13.0.0 virtio driver crashes and the 13.1.0 driver stops processing, i.e., it does not attach to the device.

Workaround:
Do not disable mergeable buffers.


655500-2 : Rekey SSH sessions after one hour

Component: TMOS

Symptoms:
Common Criteria requires that SSH session be rekeyed at least every hour

Conditions:
SSH connections to or from the BIG-IP system.

Impact:
SSH sessions are rekeyed in response to the quantity of data transferred, or on user demand, but not on the basis of elapsed time

Workaround:
If time-based rekeying is required in your environment, edit the SSH configuration to include a RekeyLimit with both data and time parameters using a command similar to the following:
tmsh modify sys sshd include 'RekeyLimit 256M 3600s'

Outbound SSH client connections can be modified by adding the same RekeyLimit configuration to /config/ssh/ssh_config or by including that option on the command line when calling the ssh client.


655432-6 : SSL renegotiation failed intermittently with AES-GCM cipher

Solution Article: K85522235

Component: Local Traffic Manager

Symptoms:
SSL failed to renegotiate intermittently with AES-GCM cipher because IV is not properly updated when a change cipher spec message is received.

Conditions:
This failure is more likely to occur during mutual authentication.

Impact:
Some servers authenticate client using renegotiation. This issue prevents their clients from properly connecting to the servers.

Workaround:
Disable AES-GCM cipher.


655357-3 : Corrupted L2 FDB entries on B4450 blades might result in dropped traffic

Solution Article: K06245820

Component: TMOS

Symptoms:
ARP replies reach front panel port of B4450 blades but fail to reach TMMs.

This occurs because the switch in the B4450 blade has an L2 learning issue in the switch fabric that requires the system to correct the new L2 FDB entries learned on Higig trunks. The L2 module runs in poll mode by default, which is exposed to a 3-second race window in software, during which learning events in the switch hardware for a given L2 FDB entry can be lost. That can lead to corrupted L2 FDB entries and cause traffic hitting the corrupted L2 FDB entries to fail.

Conditions:
-- An L2 FDB entry is learned on Higig trunk.
-- Multiple L2 learning events happen on the L2 FDB entry during the 3-second race window in software.

Impact:
The traffic hitting the corrupted L2 FDB entry will be dropped by the switch.

Workaround:
Delete the corrupted L2 FDB entries and cause the switch to re-learn them.

To do so, identify the affected VLAN and flush L2 FDB entries on that VLAN using the following command: tmsh delete net fdb vlan {vlan_name}.


655211-4 : bigd crash (SIGSEGV) when running FQDN node monitors

Component: Local Traffic Manager

Symptoms:
bigd processing FQDN node monitors may crash due to a timing issue when processing probe responses.

Conditions:
bigd is configured for FQDN node monitors.

Impact:
bigd crashes (SIGSEGV). The system restarts bigd automatically, and monitoring resumes. No other action is needed.

Workaround:
Although no workaround is available for bigd configured for FQDN node monitors, this crash occurs due to a timing issue, and should be rare.

IPv6 traffic generated from the host, either from a host daemon, monitors, or from the command line, may use an MAC and IPv6 source address from a different VLAN.

Conditions:
- Multiple vlans with IPv6 configured addresses.
- Multiple routes to the same destination, either the same or more specific, default routes, etc. that cover the traffic destination.
- Changes in routes that will cause the traffic to the destination to shift from one vlan and gateway to another. This can be typically observed with dynamic routing updates.

Impact:
Traffic to the destination may fail due to using incorrect source IPv6/MAC address.
This may cause monitor traffic to fail.

Workaround:
Continuous traffic to the IPv6 link-local nexthops can avoid this issue.
This may be achieved by a script or an external monitor pinging the nexthop link-local address using the specific vlan.


651713 : Passive mode and untagged frames

Component: Local Traffic Manager

Symptoms:
When port is configured in passive mode, to handle untagged frames, the system requires a VLAN to be configured on the system.

Conditions:
-- When port is operating in passive mode.
-- Handling untagged frames.

Impact:
Must define a VLAN to process untagged data received on port operating in Passive mode. Might impact system performance.

Workaround:
Use the following procedure:
1. Create a VLAN.
2. Assign passive mode port as an untagged member of the VLAN.


651681-3 : Orphaned bigd instances may exist (within multi-process bigd)

Solution Article: K49562354

Component: Local Traffic Manager

Symptoms:
When multi-process 'bigd' is configured, orphaned 'bigd' instances may be exit; such as an orphaned 'bigd.1' alongside the active 'bigd.1'.

Conditions:
-- db variable Bigd.NumProcs to 2 or higher.
-- System monitors with long timeouts (such as ~183 seconds or longer), might also be relevant.

When 'bigd' manages monitor configurations that results in no monitoring activity for a long time (such as due to long monitor timeouts), the operating system may temporarily suspend (and later resume) the 'bigd' process. The system might treat the 'bigd' process as if it were "hung", and start another 'bigd' instance without explicitly terminating the suspended 'bigd' process.

Impact:
The suspended 'bigd' process consumes process memory. The process might be suspended (consuming no CPU resources), or running, which might result in "double-monitoring" the resources assigned to that 'bigd' process.

Note: If double-monitoring occurs, monitor status should be correct, but the double-monitoring unnecessarily consumes extra resources.

Workaround:
Configure 'bigd' to run as a single process. To do so, set the db variable Bigd.NumProcs to 1.

Shortening monitor timeouts can reduce the possibility of a 'bigd' process being (temporarily) suspended by the operating system.


651651-1 : bigd can crash when a DNS response does not match the expected value

Workaround:
No workaround at this time.


651640-2 : queue full dropped messages incorrectly counted as responses

Component: Service Provider

Symptoms:
negative number of active response messages reported on sipsession profile stats

Conditions:
If a request message is dropped because the sip filter's ingress message queue is full, the wrong stats is incremented

Impact:
Counting the dropped request messages as response messages causes the calculation of the accepted response messages to be incorrectly calculated, thus producing a negative value.


651541-1 : Changes to the HTTP profile do not trigger validation for virtual servers using that profile

Solution Article: K83955631

Component: Local Traffic Manager

Symptoms:
Changing the HTTP profile does not trigger validation for virtual servers, so no inter-profile dependencies are checked.

Conditions:
Using an HTTP profile with a virtual server that uses other profiles that have settings that are mutually exclusive with those of the HTTP profile.

Impact:
The system will be in an invalid state. One immediate way this can be seen is when syncing to a peer. The sync operation does not complete as expected.

Workaround:
Use the error messages in the logs to determine how to change the configuration to return the system to a valid state.


651413-1 : tmsh list ltm node does not return an error when node is not exist

Solution Article: K14429395

Component: Access Policy Manager

Symptoms:
When the BIG-IP system is configured as SAML SP, there are two bindings supported for SLO profile: HTTP-Redirect and HTTP-POST (default option). If the BIG-IP system is configured to initiate SAML SP SLO profile with redirect binding - tmm may restart.

Conditions:
-- Configure the BIG-IP system as SAML SP.
-- Configure HTTP-Redirect binding for SLO profile.
-- Initiate SLO on SAML SP.

Impact:
tmm restarts. Traffic disrupted while tmm restarts.

Workaround:
Reconfigure the BIG-IP system to use HTTP-POST binding for SLO profile. Configuration should be changed on IDP connector objects.

651135-2 : LTM Policy error when rule names contain slash (/) character

Component: Local Traffic Manager

Symptoms:
Beginning with v12.0.0, there has been additional validation for LTM Policy rule names to allow only certain valid characters. Prior to v13.1.0, the slash (/) character was included in the set of valid characters.

But because the slash character is used as a delimiter in the BIG-IP virtual path hierarchy (e.g., /Common/my_policy/my_rule), extra slashes in a rule name causes validation problems because the rule appears to the system as having additional path segments.

Conditions:
LTM Policy rule contains the slash (/) character.

Impact:
Configuration will not load.
Configuration may load, but admin GUI may not show policy rule.

Workaround:
In the bigip.conf file, the LTM Policy rule names can be manually edited to either remove the illegal character or to substitute a valid character.

For example, the following policy won't load because the rule name contains a slash (/) character:
   
    ltm policy mypolicy {
    ...
       rules {
          /testperson/a {
    ...
    }

But it will load when the slash (/) characters are changed to a legal character, such as underscores (_):
    ltm policy mypolicy {
    ...
       rules {
          _testperson_a {
    ...
    }

- Virtual server auto-lasthop set to 'enable'

(2)
- Global auto-lasthop set to 'disable'
- VLAN auto-lasthop set to 'disable'
- Virtual server auto-lasthop set to 'enable'

With the configuration below, FTP data connection will improperly use the auto-lasthop:
(1)
- Global auto-lasthop set to 'enable'
- VLAN auto-lasthop set to 'default'
- Virtual server auto-lasthop set to 'disable'

(2)
- VLAN auto-lasthop set to 'enable'
- Virtual server auto-lasthop set to 'disable'

Impact:
FTP data connection may fail to be established.

Workaround:
Use routing instead of auto-lasthop.

650317-2 : The TMM on the next-active panics with message: "Missing oneconnect HA context"

Component: Local Traffic Manager

Symptoms:
The next-active TMM panics with message: "Missing oneconnect HA context" on a virtual which doesn't have one-connect on the active.

Conditions:
A mirrored virtual is configured with one-connect on the next-active but no one-connect profile is present on the active. This can occur when the config-sync connection between peers is down or auto-sync on the device group is disabled. The next-active expects a one-connect HA context but the active does not send it.

Impact:
Connections on the active are not mirrored while the next-active restarts.

Workaround:
Resolving configuration differences between the active and next-active will prevent this panic.

Conditions:
An iApp LX package was installed on two devices *before* those devices were joined into a Device Group.

Impact:
The standby device is missing critical iApp data.

Workaround:
To avoid this situation, join devices in a Device Group before installing packages. When the situation has not been avoided, to synchronize the standby device, run these two commands on it:

1. restcurl /shared/iapp/global-installed-packages -X DELETE
2. restcurl /shared/gossip -d '{"copyStateFrom":"1.2.3.4"}'

For the IP address in command 2, use the Management address of the active device.

Conditions:
This occurs when booting up public cloud configurations of Virtual Edition (VE).

Impact:
Potentially unacceptable long boot times.

Workaround:
None.


649613-2 : Multiple UDP/TCP packets packed into one DTLS Record

Component: Access Policy Manager

Symptoms:
The system converts the server provided packet into PPP buffers. These PPP packets are used to pack into DTLS records. Currently there is a limit of about 14 KB of DTLS records, such that the system can pack multiple PPP records into one DTLS record.

However, creating bigger DTLS record can cause server IP Fragmentation. In the lossy environment, losing one IP fragment can cause the complete DTLS record to be lost, resulting in poor performance.

Conditions:
Multiple UDP/TCP packets packed into one DTLS Record.

Impact:
In networks with packet losses, the APM end-user application might suffer poor network performance.

Workaround:
None.

Component: TMOS

Symptoms:
An HSB transmitter failure may occur if global COS queues enabled. The HSB transmitter failure is logged in the TMM log files.

Conditions:
With global COS queues enabled, the HSB's watchdog loopback packets are sent on HSB ring 2, instead of ring 0. If HSB ring 2 is heavily utilized, this could cause the loopback packets to be dropped. If this occurs, then the watchdog may trigger an HSB transmitter failure.

Impact:
If this issue occurs then the BIG-IP is rebooted.

Workaround:
Do not use global COS queues.


648320-2 : Downloading via APM tunnels could experience performance downgrade.

Component: Local Traffic Manager

Impact:
The configuration change does not take effect.

Workaround:
Explicitly set the DB variable to the desired value.


647812-4 : /tmp/wccp.log file grows unbounded

Component: TMOS

Symptoms:
WCCP uses /tmp/wccp.log as output for Diagnostic information,
independent of log level or db key. This file can grow unbounded if there are never any WCCP packets sent. If packets are sent the file is cleaned up automatically.

Conditions:
This can occur if WCCP is configured but never goes beyond negotiation.

Impact:
/tmp/wccp.log grows unbounded, filling up the disk.


647706-1 : iOS RDP client fails to connect to RD Connection Broker via APM's Native RDP resource

Component: Access Policy Manager

Symptoms:
iOS RDP client fails to connect to Windows Server 2012/2016 with RD Connection Broker role installed via APM's Native RDP resource.
When user launches Native RDP resource from APM Webtop, RDP client shows following error messages:
-- Can't connect to the Remote Desktop Gateway. Contact your network administrator for assistance. (Error code: 0x03000008).
-- Disconnected from server vpn.example.com with error code 0x00000003.

Conditions:
Using iOS client to connect to Windows Server 2012/2016 with RD Connection Broker role installed via APM's Native RDP resource.

Impact:
Connection from RD client to Terminal Server via BIG-IP APM fails.

Workaround:
iOS does not work in this case, but you can connect using a client device besides iOS such as Android.


647158-4 : Internal virtual server inherits CMP hash mode from parent virtual server

Solution Article: K76581555

Component: Service Provider

Symptoms:
An internal virtual server might behave in unexpected ways, such as abort a client connection before connecting to the server.

Conditions:
Virtual server with request-adapt or response-adapt profile and a vlan with 'cmp-hash' mode 'src-ip'.
Internal virtual server without a VLAN or 'cmp-hash' setting.

Impact:
The internal virtual server might sometimes abort when attempting to make a connection to the server. This occurs after a successful load-balance pick indicated by the LB_SELECTED event, but before a TCP SYN packet is sent to the server. As a result the parent virtual performs the service-down-action configured in the request-adapt or response-adapt profile.

Workaround:
If possible, do not use the cmp-hash mode 'src-ip'.


647151-2 : CPU overtemp condition threshold is 75C

Component: TMOS

Symptoms:
A CPU overtemp condition is logged when a B4450 CPU reaches 75C.

Conditions:
CPU temperature is only 75C and ambient temperature in the blade is in the normal range.

Impact:
Since the temperature threshold is set too low, the warning does not indicate an actual problem.

Workaround:
None.


647108-2 : Deletion of saml-idp-connector may fail depending on the order in which related objects are deleted within a transaction

Component: Access Policy Manager

Symptoms:
The system posts messages similar to the following even when the server associated to the connector is also being deleted in the same transaction:
01070734:3: Configuration error: apm aaa saml-idp-connector: Cannot delete saml-idp-connector /Common/saml_connector because it is being used by aaa-saml-server (/Common/saml_server_test1

Conditions:
When deleting saml-idp-connector first then the associated saml server.

Impact:
Cannot delete saml-idp-connector and associated server in that specific order.

Workaround:
Delete saml server first and then delete the saml connector.


647071-1 : Stats for SNATs do not work when configured in a non-zero route domain

Component: Local Traffic Manager

Symptoms:
When creating SNAT in a Route Domain different from 0, the command 'tmsh show ltm snat' does not report any statistics.

Conditions:
This occurs on all SNATs in a route domain other than 0.

Impact:
No statistics for the SNATs

Workaround:
None.


646890-2 : IKEv1 auth alg for ike-phase2-auth-algorithm sha256, sha384, and sha512

Solution Article: K12068427

Component: TMOS

Symptoms:
Changing the IKEv1 phase2 authentication algorithm to sha256, sha384, or sha512 does not work immediately, without a restart of the tmipsecd daemon.

Conditions:
If you change the ike-phase2-auth-algorithm attribute (inside an instance of ipsec-policy) to a value of sha256, sha384, or sha512, this causes a parse error when received by racoon. Thus the change does not take affect without a racoon restart.

Impact:
Cannot switch IKEv1 ipsec-policy to sha256, sha384, or sha512 authentication without either restarting BIG-IP or restarting tmipsecd.

Workaround:
Restarting the tmipsecd daemon causes a restart of all racoon processes, which causes the config to be re-read and then IKEv1 IPsec works correctly with SHA authentication algorithms.


646804-1 : call to tmctl in diskmonitor for the tmstat vmcp_stat table results in error: tmctl: vcmp_stat: No such table.

Component: TMOS

Symptoms:
diskmonitor added monitoring functionality for VM disks. As a result there is an call to tmctl in diskmonitor for the tmstat vmcp_stat table.

However, this call is also done on non-vCMP systems, which results in an error: tmctl: vcmp_stat: No such table.

Conditions:
Run diskmonitor on a non-vCMP system.

Impact:
The system posts the following error: tmctl: vcmp_stat: No such table. There is no functional issue when receiving this message on non-vCMP systems, so you can disregard the message.

Workaround:
None.


646800-1 : A part of the request is not sent to ICAP server in a specific case

Component: Application Security Manager

Symptoms:
The portion of the request that is not sent is not checked for viruses

Conditions:
ICAP is configured.

Impact:
There might be a false negative on anti-virus check

Workaround:
N/A


646643-1 : HA standby virtual server with non-default lasthop settings may crash.

Component: Local Traffic Manager

Symptoms:
A long-running high availability (HA) Standby Virtual Server with non-default lasthop settings may crash TMM.

Conditions:
-- HA standby virtual server is configured on the system with non-default lasthop configurations (e.g., lasthop pools or autolasthop disabled, etc).

-- That virtual server receives more than 2 billion connections (2 billion is the maximum value of a 32-bit integer).

Impact:
TMM on the next-active device crashes. The Active device is not affected. Traffic disrupted while tmm restarts.

Workaround:
None.


646604-1 : Client connection may hang when NTLM and OneConnect profiles used together

Component: Local Traffic Manager

Symptoms:
In deployments where a NT LanManager (NTLM) authentication profile and a OneConnect profile are used together in a LTM virtual server to label an authenticated connection to a Domain Controller (DC); if the persisted connection to the DC is re-used, the connection may hang. A connection in this state may not be cleaned up by the sweeper, resulting in a memory leak.

Conditions:
The NTLM and OneConnect profiles are associated with a LTM virtual server.

Impact:
A client connection won't be serviced and TMM memory will leak. Over a long time period, this may result in more widespread service disruptions.

Workaround:
Avoid the use of OneConnect profiles on virtual servers that use NTLM profiles. The connections to the Domain Controller won't be pooled, but all other features will be retained.


646495-1 : BIG-IP may send oversized TCP segments on traffic it originates

Component: Local Traffic Manager

Symptoms:
Traffic from the Linux host on BIG-IP may send TCP segments larger than the advertised TCP MSS of a remote host.

Conditions:
Received TCP MSS (plus protocol overhead) smaller than configured MTU of interface.
Linux host sending large TCP segments, such as SNMP getbulk replies.

Impact:
TMM may send traffic to a TCP host that exceeds the host's advertised MTU.

Workaround:
disable segmentation offload for the nvic


646443-2 : EphemeralNode may be errantly created in bigd, causing crash

Solution Article: K54432535

Component: Local Traffic Manager

Symptoms:
When FQDN Ephemeral Nodes are being used at the same time as static Node objects, and there is change in those objects, either via DNS resolver changes or manual changes to static nodes, there exists a chance where one may be misidentified as the other during an update, causing a crash in bigd.

Conditions:
FQDN Nodes and Static Nodes being used. Change in node settings or creation/deletion of nodes.

Impact:
Bigd crashes, causing interruption in monitoring.

Workaround:
Avoid use of FQDN Nodes and Pool Members; use only static-IP Nodes/Members instead.


645770 : MAC address must be configured on virtual function

Component: TMOS

Symptoms:
There may be a system outage if the virtual function device is not provided a MAC address from the hypervisor.

Conditions:
-- Virtual Edition.
-- Fortville virtual function device not provided a MAC address from the hypervisor.

Impact:
System outage.

Workaround:
Ensure that a MAC address is configured for each virtual function.


645729-2 : SSL connection is not mirrored if ssl session cache is cleared and resume attempted

Component: Local Traffic Manager

Symptoms:
SSL connection is not mirrored if ssl session cache is cleared before attempting to resume the ssl connection.

Conditions:
A previous ssl session is attempting to resume the connection after the ssl session cache has been cleared.

Impact:
Connection is established but is not mirrored.

Workaround:
Could be avoided by disabling ssl session cache.


645684-3 : Flash application components are loaded into wrong ApplicationDomain after Portal Access rewriting.

Component: Access Policy Manager

Symptoms:
Flash ActionScript3 application components are loaded into incorrect ApplicationDomain and in some rare cases this may cause errors in application.

Conditions:
This can occur when viewing Flash video while connected to APM.

Impact:
Flash applications might fail to render through Portal Access.

Workaround:
None


645635-1 : Sflow may use 0.0.0.0 as Agent Address in 2 core vCMP guests

Component: Local Traffic Manager

Symptoms:
VCMP clusters without configured slot-specific management-ip addresses will report 0.0.0.0 for: sFlow (Agent Address), High Speed Logging (in certain log messages), and IPFIX (domain ID).

When creating VCMP guests, the cluster's floating IP address is configured on the host using a command of the form: 'tmsh modify vcmp guest guest0 management-ip 10.1.2.3/24'; however, this will leave the slot-specific management IP address unconfigured. In this case, the affected services (sFlow, HSL, and IPFIX) will report 0.0.0.0 as their management IP address.

Conditions:
- vCMP guest deployed on a chassis with only Cluster IP set, and no individual blade IP addresses configured.
- sflow and/or HSL and/or IPFIX configured.

Impact:
sflow, HSL, and IPFIX may incorrectly use 0.0.0.0 when identifying the BIG-IP system by management IP address. For sFlow, this is the default Agent Address. For HSL, certain log messages which identify the origin BIG-IP system by its management IP address will use this default value. For IPFIX, the domain ID will use this default value.

Workaround:
Configure cluster blade IP addresses. For example, to set the slot-specific management IP address on a VCMP guest which runs on a single slot, use a command similar to the following:

tmsh modify sys cluster default members { 1 { address 10.1.2.3 } }


645615-1 : zxfrd may fail and restart after multiple failovers between blades in a chassis.

Component: Global Traffic Manager (DNS)

Symptoms:
zxfrd may fail and restart after multiple failovers between blades in a single chassis.

Conditions:
DNS Express must be configured in a multi-blade chassis. If a blade transitions from active to backup to active states and the DNS Express (tmmdns.bin) database has been re-created while the blade was in backup status, zxfrd may fail when attempting to reference old data.

Impact:
zxfrd will create a core file and restart, picking up where it left off.

Workaround:
None.


645206-2 : Missing cipher suites in outgoing LDAP TLS ClientHello

Solution Article: K23105004

Component: TMOS

Symptoms:
BIG-IP drops all SHA256 and SHA384 ciphers in the advertised ciphers list in the Client Hello when initiating LDAP/TLS with a pool member (in the case of a monitor). The same behavior is also seen for BIG-IP system auth via LDAP or AD when TLS is used.

Conditions:
You have LDAP servers requiring SHA256 and SHA384 ciphers for LDAP/TLS authentication.

Impact:
Servers requiring SHA for LDAP/TLS authentication will no longer be able to authenticate. This could suddenly break LDAP auth if you are upgrading from version 11.x where SHA256 and SHA384 existed.

Workaround:
Configure LDAP servers not to be dependent on SHA256 and SHA384 ciphers.


645197-4 : Monitors receiving unique HTTP "success" response codes may stop monitoring after status change

Component: Local Traffic Manager

Symptoms:
Monitors that return unique HTTP/1.1 200 codes (indicating success) will accumulate in the monitor history; upon monitor status change (such as to "fail"), this history is sent (from 'bigd' to 'mcpd') to indicate that monitor's new-status, plus historical context. This history may grow too large if no monitor status is detected for an extended time (such as days or weeks) when unique status codes are returned from the web server and accumulated in the history. Upon a monitor status change (such as from "success" to "fail"), notification from 'bigd' to 'mcpd' will fail due to this too-large history, resulting in the monitor remaining in its previous state (i.e., "success"). 'bigd' properly records the monitor status and continues to monitor; but 'mcpd' was not notified of that status change (due to message-send failure from the history being too large).

This is typically not an issue when the web server returns the same HTTP/1.1 200 code (indicating "success"), as 'bigd' will elide/merge the response-value into the monitor history (so the history does not continue to grow). However, for web servers generating a unique value for each success code (for example, by appending an always-unique transaction ID to the end of the HTTP/1.1 200 response), the history will continue to grow for that monitor until a status-change is detected.

Conditions:
Web server returns unique HTTP/1.1 200 (success) codes; and success history is accumulated for that monitor without status-change for extended time (typically days-or-weeks); followed by a monitor status change (such as from "success" to "fail").

Impact:
The monitor will remain in the "success" state, as the status-change will be "lost" ('bigd' properly recognizes the changed monitor status, but 'mcpd' is not notified of the change). The system may eventually self-correct, such as when 'bigd' detects further monitor status changes, and again forwards status-change notifications for that monitor to 'mcpd'.

Workaround:
Modify the web server configuration to not respond with unique HTTP/1.1 200 codes; thus, receiving the same return-code will elide/merge with previously accumulated values in the monitor history.


645179-1 : Traffic group becomes active on more than one BIG-IP after a long uptime

Component: TMOS

Symptoms:
Traffic-groups become active/active for 30 seconds after a long uptime interval.

Note: Uptime required to encounter this issue is dependent on the number of traffic groups: the more traffic groups, the shorter the uptime.

For example:

-- For 7 traffic groups, the interval is ~710 days.
-- For 15 traffic groups, the interval is ~331 days.

Conditions:
-- Two or more BIG-IP systems defined in a device group for sync/failover.
-- There is one or more traffic groups configured.
-- The BIG-IP systems have a long uptime.

Impact:
Outage due to traffic-group members being active on both systems at the same time.

Workaround:
There is no workaround.

The only option is to reboot all the BIG-IP units in the device group on a regular interval. The interval is directly dependent on the number of traffic groups.


645058-4 : Modifying SSL profiles in GUI may fail when key is protected by passphrase

Solution Article: K93819312

Component: Local Traffic Manager

Symptoms:
When a client SSL profile has a Certificate Key Chain (CKC) entry with a passphrase-protected key, attempting to modify/update the profile via the GUI may fail, and produce an error similar to the following:

01070313:3: Error reading key PEM file <Key_File_Path> for profile <Profile_Name>: error:0906A068:PEM routines:PEM_do_header:bad password read.

This can occur even when the passphrase already in the SSL profile is correct.

Conditions:
Upgrading a BIG-IP system from a version prior to BIG-IP v11.5.0 to v11.5.0 or later, while having a passphrase-protected key specified in the profile.

Alternately, creating an SSL profile with a custom cert-key-chain name that references a passphrase-protected key, e.g.:

tmsh create ltm profile client-ssl example-profile defaults-from clientssl cert-key-chain replace-all-with { no { cert protected.crt key protected.key passphrase password } }

Impact:
User cannot update client SSL profile via the GUI.

Workaround:
Modifications to the profile can be made from tmsh. Alternately, delete the CKC and recreate it.


645036 : Removing pool from virtual server does not update its status

Solution Article: K85772089

Component: Local Traffic Manager

Symptoms:
Removing a pool from a virtual server does not update the virtual server's status.

Conditions:
1) Create a pool and assign a monitor to it.
2) Ensure the pool goes green.
3) Create a virtual server without assigning the pool to it.
4) Ensure the virtual server stays blue (unknown).
5) Associate the pool to the virtual server.
6) Ensure the virtual server goes green (available).
7) Remove the pool from the virtual server.
8) The virtual server should go back to blue (unknown); however, it doesn't and stays green.

Impact:
The virtual will appear to be associated with a monitored pool when it is not. This should have no functional impact on the virtual server, since a virtual server without a pool has no traffic to pass, and associating a pool with the virtual server will reflect the pool status.

Workaround:
Restart the BIG-IP system. The status should be blue/unchecked once again after the BIG-IP is restarted.

Note: Restarting the BIG-IP system might have an impact on existing traffic. Because this issue is cosmetic, this workaround is not recommended for BIG-IP systems in production.


644979-1 : Errors not logged from hourly 1k key generation cron job

Solution Article: K02641631

Component: TMOS

Symptoms:
Errors from the 1k key generation hourly cron job do not get logged as intended from the hourly 1024-bit key generation task.

Conditions:
This occurs during hourly generation of ephemeral keys.

Impact:
Errors from the 1k key generation hourly cron job do not get logged, and hourly generation of ephemeral keys fails.

Workaround:
Change "loggcercmd" to "loggercmd" in /etc/cron.hourly/genkeys-1024.


644975-2 : /var/log/maillog contains errors when ssmtp is not configured to use a valid mailhost

Solution Article: K09554025

Component: TMOS

Symptoms:
Entries in /var/log/maillog similar to the following:
err sSMTP[25793]: Unable to connect to "localhost" port 25.

Conditions:
This happens when certain crontab configuration files do not specify MAILTO="" at the top, and some of the scripts appearing in those files output something to STDOUT or STDERR. This causes the system to try to send an email with that output, which will fail when ssmtp is not configured to use a valid mailhost.

Impact:
Error messages logged to /var/log/maillog. Note that the maillog file is rotated so it doesn't fill up the /var/log volume.

Workaround:
1) Run the "crontab -e -u root" command; this will open the root user's crontab configuration in your default text editor.

2) Move the MAILTO="" line to the top of the file, right under the "# cron tab for root" banner.

3) Save the file and exit the text editor to install the root user's new crontab configuration.

4) Using a text editor of your choice, replace MAILTO=root with MAILTO="" in the /etc/crontab file.

5) Using a text editor of your choice, replace MAILTO=root with MAILTO="" in the /etc/cron.d/0hourly file.

6) To verify that MAILTO=root does not appear anywhere else, run the following command: grep -i -r mailto /etc/cron*.

7) If the previous command shows MAILTO=root still appears in some files, also modify those file so that MAILTO=root becomes MAILTO="".


644873-3 : ssldump can fail to decrypt captures with certain TCP segmenting

Solution Article: K97237310

Component: Local Traffic Manager

Symptoms:
ssldump fails to decrypt a capture. In rare circumstances, ssldump can crash.

The ssldump might display output similar to the following:
1 25 0.4781 (0.0000) S>CShort record
Unknown SSL content type 224
1 26 0.4781 (0.0000) S>CShort record
Unknown SSL content type 142
...
1 30 0.4781 (0.0000) S>CShort record
1 31 0.6141 (0.1359) S>CV231.213(45857) application_data

Conditions:
ssldump is decrypting traffic where an SSL record header spans TCP segments.

Impact:
ssldump can fail to fully decrypt the capture starting at the frame where the SSL record spans a TCP segment. Depending on the remaining data in the TCP stream, ssldump can crash.

Workaround:
None.


644822-1 : FastL4 virtual server with enabled loose-init option works differently with/without AFM provisioned

Component: Advanced Firewall Manager

Symptoms:
If AFM provisioned, a FastL4 virtual server with enabled loose-init option drops all RST packets that do not relate to any existing flows.

This behavior does not match the BIG-IP behavior when AFM is not provisioned.

Conditions:
AFM provisioned.
-- FastL4 virtual server.
-- Loose-init option enabled.

Impact:
RST packets that do not relate to any existing flows are dropped, while they should not be dropped if the loose-init option enabled.

Workaround:
No workaround.


644799-2 : TMM may crash when the BIG-IP system processes CGNAT traffic.

Solution Article: K42882011

Component: TMOS

Symptoms:
TMM may crash when the BIG-IP system processes CGNAT traffic.

Conditions:
A TMM connflow related to CGNAT traffic is expired.

Impact:
Traffic disrupted while tmm restarts.

Workaround:
None.


644750 : 'epsec' tool fails in older version after use in newer version.

Component: Access Policy Manager

Symptoms:
Update to v13.0.0 removes EPSEC backward compatibility with BIG-IP systems running software versions earlier than 13.0.0.

Conditions:
Use 'System :: Software Management : Antivirus Check Updates' facilities in v13.0.0, boot back to 11.6.x or 11.5.x, and then run an EPSEC command such as the following: epsec -v version

Impact:
Errors are reported; EPSEC commands are not functional.

Workaround:
Try the EPSEC commands again after removing all environment locks on the shared RPM database using the following command:

rm /shared/lib/rpm__*.db


644725-2 : Configuration changes while removing ASM from the virtual server may cause graceful ASM restart

Solution Article: K01914292

Component: Application Security Manager

Symptoms:
Configuration changes while removing ASM from the virtual server may cause graceful ASM restart.

Conditions:
A reconfiguration / headers configuration happens while the ASM is removed from a VIP. This may happen especially in scripts that create a config or remove a config.

Impact:
ASM restarts. The system goes offline. A failover may happen.

Workaround:
Ensure that there is some time between setting a configuration to removing ASM from the VIP.


644723-2 : cm56xxd logs link 'DOWN' message when an interface is admin DISABLED

Component: TMOS

Symptoms:
If you disable an interface, the interface is erroneously logged as DOWN:

Feb 12 23:14:09 i5800-R18-S30 info bcm56xxd[8210]: 012c0015:6: Link: 1.1 is DOWN

Conditions:
This is logged when disabling an interface.

Impact:
Log message says the interface is DOWN, it should say DISABLED.


644565-2 : MRF Message metadata lost when routing message to a connection on a different TMM

Component: Service Provider

Symptoms:
The system might choose to create a new outgoing connection when there is an available exiting connection that can be used.

Conditions:
When a message is forwarded to another TMM for delivery, an internal state might be lost.

Impact:
Messages should be delivered correctly as the metadata is lost after routing. There might be an impact if routing is retried and the ignore-peer-port setting is lost. This might cause a new connection to be created when an available existing connection exists.

Workaround:
None.


644447-1 : sync_zones script increasingly consumes memory when there is network connectivity failure

Component: Global Traffic Manager (DNS)

Symptoms:
sync_zones memory usage exponentially increases during network disruption

Conditions:
Network interruption occurs during the "Retrieving remote DNS/named configuration" stage of a gtm_add operation.

Impact:
Memory increases exponentially, potentially resulting in an eventual out-of-memory condition.

Workaround:
None.


644418-1 : Do not consider self-signed certificate in hash algorithm selection when Forward Proxy forges a certificate

Component: Local Traffic Manager

Symptoms:
SSL Forward Proxy signs a forged certificate with a hash algorithm. This selected hash algorithm is the weakest algorithm from the certificates in the server certificate chain including the self-signed certificate.
Many of the self-signed certificates use the SHA1 hash algorithm, which is not acceptable to many sites. The SSL handshake may be rejected.

Conditions:
This may occur when SSL Forward Proxy is in use.

Impact:
Forged certificate with SHA1 hash algorithm may be rejected during SSL handshake and the SSL handshake will then fail.

Workaround:
None.


644220-4 : Flawed logic when retrieving an LTM Virtual Server's assigned Link on the LTM Virtual Server Properties page

Component: Global Traffic Manager (DNS)

Symptoms:
Under LTM :: Virtual Servers :: Properties, the "Link" value sometimes displays "none" when it should display an actual link name.

Conditions:
This happens under certain configuration of Self IP / GTM Servers / GTM Links / LTM Virtual Servers.

Impact:
When conditions are met, the Virtual Server's link information displayed is not correct.

Workaround:
None.


644184-3 : ZebOS daemons hang while AgentX SNMP daemon is waiting.

Component: TMOS

Symptoms:
ZebOS daemons hang while AgentX SNMP daemon is waiting for return from external script.

Conditions:
- Dynamic routing is enabled.
- SNMP is enabled.
- SNMP calls an external script that takes several moments to return.

Impact:
Dynamic routing may be halted for the duration of AgentX daemon waiting for return from external script.

Workaround:
Do not configure AgentX to call external scripts that take several moments to return.


643860-5 : Attempt to read or write to the file /dev/vnic can cause TMM to restart and TMM may not startup properly

Component: Local Traffic Manager

Symptoms:
There is no indication that mcpd has restarted, but the system logs messages similar to the following:

-- In /var/log/tmm:
  notice MCP connection expired early in startup; retrying.

In/var/log/ltm:
  mcpd[5747]: 01070406:5: Removed publication with publisher id TMM1.

Conditions:
The file /dev/vnic is opened by something other than BIG-IP programs.

Impact:
The TMM processes will restart and fail to come up properly.

Workaround:
To recover, reboot the system.

Note: Do not perform file open operations on /dev/vnic. There is no need to.


643813-1 : ZoneRunner does not properly process $ORIGIN directives

Solution Article: K32906881

Component: Global Traffic Manager

Symptoms:
During an import zone operation, ZoneRunner incorrectly associates the "@" directive with the zone name and not $ORIGIN specified.

Conditions:
If the zone file to be imported contains the $ORIGIN directive, the following "@" directives will reference the zone name, which is incorrect.

Impact:
Zones will not be imported correctly.

Workaround:
Use the named-compilezone tool to "normalize" the zone file before importing into ZoneRunner.

The syntax for this command is similar to the following:
named-compilezone -s full -o outputfilename zone_name input.file
(For information about the other available options, see the named-compilezone tool's man page.)

For example, given a zone file named example.com.file that contains the following information:

"example.com"
$TTL 3600
example.com. 86400 IN SOA ns1.example.com. hostmaster.ns1.example.com. 2017020201 10800 3600 604800 86400
@ IN NS ns1.example.com.
ns1.example.com. IN A 1.1.1.1
$ORIGIN alpha.example.com.
@ IN A 2.2.2.2
$ORIGIN bravo.example.com.
@ IN A 3.3.3.3

The command is as follows:

named-compilezone -s full -o example.com.file.full example.com example.com.file

The contents of the new file are:
example.com. 86400 IN SOA ns1.example.com. hostmaster.ns1.example.com. 2017020201 10800 3600 604800 86400
example.com. 3600 IN NS ns1.example.com.
alpha.example.com. 3600 IN A 2.2.2.2
bravo.example.com. 3600 IN A 3.3.3.3
ns1.example.com. 3600 IN A 1.1.1.1

Which is correct. This file can then be used to import into ZoneRunner.


643799-4 : Deleting a partition may cause a sync validation error

Component: TMOS

Symptoms:
Deleting a partition may cause the sync to peers to fail.

For example, on BIG-IP1:

tmsh delete auth partition P1
tmsh show cm sync-status
     Sync Summary
     Status Sync Failed
     Summary A validation error occurred while syncing to a remote device
     Details DG1: Sync error on BIG-IP2: Load failed from BIG-IP1 01070829:5: Input error: Invalid partition ID request, partition does not exist (P1)

Conditions:
Two or more BIG-IPs in a DSC device group, say DG1. A partition (P1) is created where the root partition folder (/P1) or a subfolder is assigned to DG1.

Objects have also been configured in the folder and the user deletes the partition, which will cause the folder and its contents to be deleted.

Impact:
The sync of this change may fail on peers.

Workaround:
Disable auto-sync on the device group if it's enabled, delete the partition on all of the peers, and re-enable auto-sync.


643777-1 : LTM policies with more than one IP address in TCP address match may fail

Solution Article: K27629542

Component: Local Traffic Manager

Symptoms:
An LTM policy using a rule that attempts to match based on a list of IP addresses may fail if more than one IP address is used.

Conditions:
LTM policy rule with a 'tcp match address' statement that attempts to match against more than one IP address.

Impact:
The action configured with the match may not be taken.

Workaround:
Use one of the following workarounds:
- Use a subnet instead of single IP addresses.
- Use a datagroup with the list of IP addresses to match.
* Datagroup option available beginning in v13.0.0.


643768-1 : Invalid entries in SNMP allowed-address and SNMP community fields can cause upgrade failure.

Component: TMOS

Symptoms:
If there are invalid entries in the SNMP allowed-address field, or in the SNMP communities source field, upgrade to v13.0.0 fails to load the configuration on validation of the input, with this error signature:

01070911:3: The requested host (<host-ip-address>) is invalid for allow in snmpd (/Common/snmpd),
Unexpected Error: Loading configuration process failed.

Conditions:
This can happen when upgrading from a release older than 13.0.0, and there is an invalid entry in the SNMP allowed-address field or communities source field, such as:

sys snmp {
    allowed-address { 1.0.0.0/2.0.0.0 "1.1.1.1 2.2.2.2" 3.3.3.3,4.4.4.4 }
    communities {
        /Common/test {
            community-name test
            source 1.0.0.0/foo
        }
    }
}

Impact:
Upgrade to 13.0.0 fails if the configuration contains these invalid values, due to input validation that was added in this version.

Workaround:
Remove the invalid entries from these 2 field types before doing an upgrade to 13.0.0.


643459-4 : Unable to login to BIG-IP Configuration Utility when BIG-IP is behind a Reverse proxy

Solution Article: K81809012

Component: TMOS

Symptoms:
When a BIG-IP management interface is accessed through a Reverse Proxy, you are not able to log in to the Configuration Utility. Instead you will see a login error, as the Reverse Proxy IP/hostname is in the Referer header instead of that of the BIG-IP.

Conditions:
You are accessing the BIG-IP Configuration Utility through a Reverse Proxy.

Impact:
You are unable to login to the Configuration Utility.

Workaround:
Configure their Reverse Proxy to place the IP address of the BIG-IP in the Referer header.


643411-1 : High memory usage for avrd statistics

Solution Article: K59119323

Component: Application Visibility and Reporting

Symptoms:
On B4450 blade, the avrd log receives constant error messages similar to the following in ltm.log/avrd.log:


 err merged[40445]: 011b0900:3: TMSTAT error tmstat_create_scripts: Resource temporarily unavailable.

 User timeout 5 is reached
 failed subscribe to avr_blade:

Conditions:
Configuration includes:
1. DoS profile enabled for L7 and L3-4.
2. ASM policy is attached.
3. AVR profile with traffic capture is enabled, with remote logger profile.
4. Off-system processing is enabled.

Impact:
This causes an increase in tmstat memory usage.

Workaround:
There is no workaround at this time.


643210-3 : Restarting MCPD on Secondary Slot of Chassis causes deletion of netHSM keys on SafeNet HSM

Component: Local Traffic Manager

Symptoms:
When mcpd (re)starts on a secondary slot, part of the initialization process triggers the delete of any netHSM keys on the SafeNet HSM.

Conditions:
This occurs on a chassis that is configured to use a SafeNet netHSM.

Impact:
The key is removed from the HSM and must be reimported to the HSM from a backup, if it exists.

Workaround:
When rebooting a secondary blade, temporarily remove the BIG-IP from the network it uses to connect to the SafeNet HSM. Once the BIG-IP is Active, it is safe to reconnect it to the network.


643041-1 : Less than optimal interaction between OneConnect and proxy MSS

Solution Article: K64451315

Component: Local Traffic Manager

Symptoms:
When a client with low MSS is the first to establish a OneConnect flow pair and proxy MSS is enabled, the serverside will share the same low MSS. Successive connections from full-MSS clients may utilize this server-side flow, resulting in suboptimal throughput.

Conditions:
Configure a virtual server with both OneConnect and proxy MSS. Note: Proxy MSS is enabled by default beginning with v12.1.0.

Impact:
Decreased throughput, possible congestion due to small segments.

Workaround:
In some instances, it may be sufficient to disable proxy MSS. This too has the potential to increase segment count and decrease throughput.


642982-1 : tmrouted may continually restart after upgrade, adding or renaming an interface

Component: TMOS

Symptoms:
tmrouted continually restarts when it fails to resolve the interface index for a VLAN, VLAN group, or tunnel.

Conditions:
-- Dynamic routing configured.
-- Non-default partition name or VLAN names greater than 15 characters.

Impact:
Dynamic routing does not function. This may include monitors not functioning properly and marking pool members down incorrectly.

Workaround:
Shorten VLAN, VLAN group, or tunnel name, or move the interface into the Common partition.


642923-1 : MCP misses its heartbeat (and is killed by sod) if there are a large number of file objects on the system

Solution Article: K01951295

Component: TMOS

Symptoms:
MCP may timeout and be killed by the sod watchdog, causing mcpd to restart.

Conditions:
Certain operations, under certain conditions, on certain platforms, may take longer to complete than the mcpd heartbeat timeout (300 seconds). When that happens, the system considers mcpd unresponsive, and will kill mcpd before it has finished its task, resulting in this issue.

There are a number of ways that this issue may manifest.

For example, the default mcpd heartbeat timeout might be reached when loading a configuration file with a large number* of file objects configured (e.g., SSL certificates and keys, data-groups, APM customizations, EPSEC file updates, external monitors, or other data present in the filestore (/config/filestore)).

*Note: Depending the operations mcpd is performing, the performance of the hardware, the speed of disk access, and other potential factors, 3,000 is a relative estimate of the number of filestore objects that might cause this issue to occur.

Impact:
mcpd restarts, which causes a system to go offline and restart services.

Workaround:
To prevent the issue from occurring, you can temporarily disable the heartbeat timeout using the following command:

   modify sys daemon-ha mcpd heartbeat disable

Important: Disabling the heartbeat timer means that, should the mcpd process legitimately become unresponsive, the system will not automatically restart mcpd to recover.

Note: If you have a large number of objects (more than 3,000) in the filestore, and are able to reduce this by deleting their related configuration objects, you may be able to work around the issue.

To determine the specific cause of the issue, you can open a support case with F5, to inspect the resulting mcpd core file.


642786-1 : TMM may drop tunneled traffic when the sys db variable 'connection.vlankeyed' is set to 'disable'.

Solution Article: K01833444

Component: Local Traffic Manager

Symptoms:
The BIG-IP system may drop tunneled traffic destined for it, even though the corresponding tunnel is created correctly.

Conditions:
The local-address of a tunnel is resided in a non-default route-domain and the sys db variable 'connection.vlankeyed' is set to 'disable'. Note that the default setting of that sys db variable is 'enable'.

Impact:
The BIG-IP system may drop tunneled traffic.

Workaround:
None.


642422-1 : BFD may not remove dependant static routes when peer sends BFD Admin-Down

Impact:
gtm config load failure after upgrade.

Workaround:
Remove trailing dots or set "Domain Validation" to "none".


642068-3 : PEM: Gx sessions will stay in marked_for_delete state if CCR-T timeout happens

Component: Policy Enforcement Manager

Symptoms:
PEM sessions stay in the marked-for-delete state if CCR-T times out.

Conditions:
This occurs if PCRF does not respond to CCR-T packets from the BIG-IP system during session termination.

Impact:
PEM sessions remain in the marked-for-delete state.

Workaround:
Configure the required timeout value in the sys db variable tmm.pem.session.timeout.endpointdeleteresponse.

Note: The value must be greater than 0 (zero).


642039-1 : TMM core when persist is enabled for wideip with certain iRule commands triggered.

Component: Global Traffic Manager (DNS)

Symptoms:
tmm cores with SIGSEGV.

Conditions:
This occurs when persist is enabled for wideip, and an iRule with the following commands triggered:
forward
reject
drop
discard
noerror
host

Impact:
Traffic disrupted while tmm restarts.

Workaround:
Disable persist on wideip.

Note: Although this is not an ideal workaround, it provides a way that to use those iRule commands without causing a tmm core.


641512-5 : DNSSEC key generations fail with lots of invalid SSL traffic

Component: Local Traffic Manager

Symptoms:
DNSSEC keys can rollover periodically. This will fail, leading to no keys to sign DNSSEC queries (no RRSIG records) when the BIG-IP is handling a lot of SSL traffic with invalid certificates.

The system posts the following log signature in /var/log/ltm:
err tmm1[12393]: 01010228:3: DNSSEC: Could not initialize cipher context for key /Common/x1-zsk.

Conditions:
DNSSEC keys configured with periodic rollover. The certificate path queues an error (situations include but not limited to lots of SSL traffic with invalid certificates).

Impact:
DNSSEC key generations fail to be accepted by the TMM so that when the prior generation expires there is no valid certificate to sign DNSSEC queries.

Workaround:
Restart the TMM after the new key generation is created.


641491-1 : TMM core while running iRule LB::status pool poolname member ip port

Component: Local Traffic Manager

Symptoms:
An iRule response to a DNS request may trigger the Traffic Management Microkernel (TMM) to produce a core file and restart. As a result of this issue, you may encounter one or more of the following symptoms:

-- The BIG-IP system may temporarily fail to process traffic as it recovers from the TMM restart, and devices configured as an HA pair may fail over.
-- The BIG-IP system generates a TMM core file to the /shared/core directory.

Conditions:
This issue occurs when all of the following conditions are met:

-- Your BIG-IP DNS system is configured with a wide IP that utilizes an iRule.
-- The iRule uses the DNS_REQUEST event command LB::status to check a pool member status.
-- The iRule pool address and port are separated by white space.

Example iRule syntax:

gtm rule pool_member_selection {
    when DNS_REQUEST {
        LB::status pool pool-one member 10.0.0.10 80
    }
}

Impact:
Traffic disrupted while tmm restarts.

Workaround:
Use format 'ip:port' or vsname instead of 'ip port. Following are two examples:
1.
gtm rule rule_crash_test {
    when DNS_REQUEST {
        LB::status pool pool-one member 10.2.108.100:80
    }
}

2.
gtm rule rule_crash_test {
    when DNS_REQUEST {
        LB::status pool pool-one member pool_vs_name
    }
}


641450-4 : A transaction that deletes and recreates a virtual may result in an invalid configuration

Solution Article: K30053855

Component: TMOS

Symptoms:
Deleting and recreating a virtual server within a transaction (via tmsh or iControl REST) and trying to modify the profiles on the virtual server (e.g., changing from fastl4 to tcp) may result in an invalid in-memory configuration. This may also result in traffic failing to pass, because TMM rejects the invalid configuration.

Config load error:
    01070095:3: Virtual server /Common/vs_icr_test lists incompatible profiles.

Configuration-change-time error in /var/log/ltm:
    err tmm[22370]: 01010007:3: Config error: Incomplete hud chain for listener: <name>

Conditions:
Deleting and recreating a virtual server within a transaction (via tmsh or iControl REST) and trying to modify the profiles on the virtual server (e.g., changing from fastl4 to tcp).

Impact:
Configuration fails to load in the future.
Traffic fails to pass, because TMM rejects the configuration.

Workaround:
Within tmsh, use the following command: profiles replace-all-with.
Within iControl REST, use three separate calls:
   1. Delete virtual server.
   2. Create virtual server (with an empty profile list).
   3. Modify the virtual server's profile list.


641273-2 : port-fwd-mode mode configuration object value

Component: Local Traffic Manager

Symptoms:
The port-fwd-mode object value of an interface object is not reset to the default value on loading a UCS.

Conditions:
Saved configuration / UCS must have port-fwd-mode in default (l3) state, and the current configuration must have port-fwd-mode set to "passive" mode.

Impact:
port-fwd-mode will continue to stay in the non-default state of "passive".

Workaround:
reconfigure the port-fwd-mode to the right value and save the configuration.


641001-2 : BWC: dynamic policy category sees lower bandwidth than expected in Congested policies

Component: TMOS

640407-2 : Usage of iRule commands that try to get or set connection state during CLIENT_CLOSED iRule event may core with MRF

Solution Article: K41344483

Component: Service Provider

Symptoms:
A core may occur with message routing framework (MRF) virtuals or transport-config connections if trying to use certain iRule commands during CLIENT_CLOSED event.

Conditions:
Use of an iRule command that gets or sets state in a MRF protocol filter or MR proxy during CLIENT_CLOSED iRule event may core. This is because CLIENT_CLOSED event is raised after all state has been freed for the current connection.

Impact:
Traffic disrupted while tmm restarts.

Workaround:
Do not use iRule command to get or set state during CLIENT_CLOSED iRule event.


640395-2 : When upgrading from 10.x to a version that supports spanning VIPs, the virtual address spanning property may not be set properly

Component: Local Traffic Manager

Symptoms:
When upgrading from 10.x to version 12.1.0 or later, a network virtual address that had ARP disabled will not have spanning automatically enabled.

Conditions:
Upgrading from 10.x to 12.1.0 or later. Must have a network virtual address configured with ARP disabled when upgrading.

Impact:
If you are not actually using the spanning feature, there is no impact.

If you are using the spanning feature, it will no longer work until it is explicitly enabled. This can result in the loss of traffic, as the upstream router will be sending packets to standby systems that will now refuse to process that traffic.

Workaround:
Upgrade to an intermediate version that implements the explicit ICMP-Echo setting for virtual addresses (e.g. 11.x) and then upgrade to the desired version.

Alternatively, you can manually set the spanning property on their virtual addresses as desired (after the upgrade).


640369-1 : TMM may incorrectly respond to ICMPv6 echo via auto-lasthop when disabled on the vlan

Component: Local Traffic Manager

Symptoms:
As a result of a known issue, TMM may respond to an ICMPv6 echo request using the auto-lasthop mechanism, when this has been disabled on the vlan.

Conditions:
- Auto-lasthop disabled on the ingress vlan
- ICMPv6 echo request for a self-IP on the ingress vlan.
- Route to the client IP address via a different vlan

TMM may respond directly using the auto-lasthop feature and not via the route lookup.

Impact:
Traffic may not follow the expected path.
