Fixes and enhancements in this release

This release includes the following fixes and enhancements.

Reconnecting to the comm_srv process after lost connectivity (CR68983)
Previously, when connectivity was disrupted between WebAccelerator systems in a clustered configuration, remote WebAccelerator systems could not reconnect to the comm_srv process on the central WebAccelerator system when the connectivity issue was fixed. We have resolved this issue and remote WebAccelerator systems can now properly reconnect to the comm_srv process once connectivity is reestablished with the central WebAccelerator system.

Performing automatic license activation from a WebAccelerator system with no Internet access (CR70227)
Previously, if a user attempted to perform automatic license activation from a WebAccelerator system that had no Internet access, the WebAccelerator system would enter an infinite error loop and the Management Console would become disabled. We have resolved this issue and now if a user attempts to perform automatic license activation from a WebAccelerator system with no Internet access, the WebAccelerator system will return an error, but the Management Console will remain accessible.

Synchronizing an upgrade between primary and secondary WebAccelerator systems (CR73036)
In previous releases, when you upgraded a WebAccelerator system that was in an optional primary/secondary configuration, the installer script did not properly synchronize the upgrade to the secondary WebAccelerator system’s Management Console. We have resolved this issue and the Management Consoles now properly synchronizes after an upgrade.

MIME types and file extensions for Flash content (CR73144)
This software release includes MIME types and file extensions required for Flash documents. These new objects are located in the globalfragment.xml file.

Accessing the Administrator Tool on the WebAccelerator 400 platform (CR73242)
Previously, performance of the Administrator Tool on the WebAccelerator 400 platform was impaired. We have resolved these performance issues in this software release.

Using the Express Loader feature in a clustered configuration (CR73647)
Previously, the Express Loader feature did not work properly on remote WebAccelerator systems deployed in an optional clustered configuration. We have resolved this issue and the Express Loader feature now operates correctly on both remote and the central WebAccelerator systems.

Unnecessary DNS lookups (CR73690)
Previously, the WebAccelerator system performed unnecessary DNS lookups for host names that were already configured in the /etc/host file. We have resolved this issue and the WebAccelerator system no longer performs unnecessary DNS lookups.

Daylight Saving Time handling for US and Canada (CR73948)
The Energy Policy Act of 2005, which was passed by the US Congress in August 2005, changed both the start and end dates for Daylight Saving Time in the United States, effective March 2007. Canada is also adopting this change. We have addressed the resulting changes in this software release. To find out more about this issue, see Solution 6551: F5 Networks software compliance with the Energy Policy Act of 2005

Serial console script (CR74285)
In previous releases the serial console script, appl_console, did not run correctly and instead of displaying the WebAccelerator system’s Management Console menu, it presented the user with a log in prompt. We have corrected this issue and the appl_console script now runs correctly and properly displays the WebAccelerator system’s Management Console menu.

Idle server connections (CR76075)
In previous releases, the WebAccelerator system kept connections open to the origin web servers longer than necessary, which resulted in idle server connections that could cause potential network latency. In this software release, the WebAccelerator system’s pvac service reduces idle server connections.

Sending Accept-Encoding gzip headers (CR77972)
When enabled in the pvsystem.conf file, the WebAccelerator can send Accept-Encoding headers with the value of gzip to the origin web server to optimize bandwidth requirements in certain network configurations by compressing content. For information about how to enable this feature, see To enable the Accept-Encoding gzip feature in the Optional Configuration Change section.

CVE-2007-1856 Vixie cron vulnerability causes denial of service (CR80063)
This software release contains a fix that resolves a vulnerability issue associated with Vixie cron that can cause a denial of service. The Common Vulnerabilities and Exposures (CVE) project assigned ID CVE-2007-1856 to this vulnerability. For more information, see CVE-2007-1856.

CVE-2006-1174 Local permissions vulnerability with the shadow-utils useradd function (CR81597)
This software release contains a fix that resolves a permissions vulnerability issue related to the useradd function of the shadow-utils. The Common Vulnerabilities and Exposures (CVE) project assigned ID CVE-2006-1174 to this vulnerability. For more information, see CVE-2006-1174.

Database synchronization to the standby WebAccelerator system’s Management Console (CR82446)
In previous versions, the database synchronization to the standby WebAccelerator system’s Management Console appeared to fail, due to an issue in the logging script. We have corrected the logging script and resolved this issue.

Daylight Saving Time handling for New Zealand (CR85165)
In April 2007, the New Zealand Department of Internal Affairs announced that effective September 2007, Daylight Savings Time will be extended by three weeks. We have addressed the resulting changes in this software release.

Known issues

The following items are known issues in the current release. Maintenance release known issues are cumulative, and include all known issues for a release.

Loading pre-defined policies during initial WebAccelerator software installation (CR68441)
When performing the initial installation of the WebAccelerator software, a pre-defined policy may fail to load. If this occurs, the WebAccelerator system reports the failure in the installation log, and the policy does not display in the pre-defined policy list. To view the installation log, type the more /tmp/pvinstall.log command. If the installation log reports missing policies, see Installing pre-defined policies manually in the Workaround for known issue section.

pvac stack trace reports error (CR68783)
When the pvac process shuts down for any reason (for instance, if you use the /etc/init.d/pivia stop command to shut it down manually, or if you reboot the WebAccelerator system), and then you view the version information using the /etc/init.d/pivia versionx, the pvac stack trace reports the following error message: Caught terminating signal, probably due to invalid application state. This error is benign.

Network configuration script (CR68985)
The network configuration script does not validate network configuration settings, and the Management Console does not report any existing network misconfigurations. To avoid issues, verify your network settings carefully before saving the configuration and rebooting the WebAccelerator system. If you discover an error in your network configuration during your review, rerun the network configuration script and correct the issue before rebooting.

Providing the dossier for licensing (CR70231)
When you are using the Management Console to manually license the WebAccelerator system, the dossier does not display properly. To work around this issue, license the WebAccelerator system using the procedure described in Solution 6697: Installing a license from the command line on AskF5.


Workaround for known issue

The following section describes the workaround for the corresponding known issue listed in the previous section.

Installing pre-defined policies manually (CR68441)

If the installation log reports missing pre-defined policies after you perform the initial installation of the WebAccelerator software, perform the following steps to install the missing policies manually.

To manually install missing pre-defined policies

  1. Type the following command:

    /etc/init.d/pivia import_config -f /opt/pivia/dac/policies/predefined/FAILED_POLICY.xml -c /opt/pivia/dac/conf/pvsystem.conf -a administrator -p PASSWORD -r -u -y

    Where:

    PASSWORD is the administrator password you assigned when you installed the WebAccelerator software.
    FAILED_POLICY.xml is the name of the missing policy, as reported in the installation log.

     

  2. After the policy loads, reboot the WebAccelerator system by typing the following command:

    reboot
