1.191.2. RHBA-2009:0415: bug fix update
Note
This update has already been released (prior to the GA of this release) as errata RHBA-2009:0415
The rgmanager packages contain the Red Hat Resource Group Manager, which provides the ability to create and manage high-availability server applications in the event of system downtime.
This update applies the following bug fixes:
- The SAP resource agents included in the rpmanager package shipped with Red Hat Enterprise Linux 5.3 were outdated. This update includes the most recent SAP resource agents and, consequently, improves SAP failover support.
- Exclusive service prioritization, whereby a high-priority exclusive service can take the place of a low-priority exclusive service, is now supported when central_processing is enabled. Note: this function does not work with virtual machines.
- An issue that causes virtual machines to restart after a configuration update has been fixed.
Red Hat Resource Group Manager users are advised to upgrade to these updated packages, which address these issues.
1.191.3. RHSA-2009:1339: Low security, bug fix, and enhancement update
An updated rgmanager package that fixes multiple security issues, various bugs, and adds enhancements is now available for Red Hat Enterprise Linux 5.
This update has been rated as having low security impact by the Red Hat Security Response Team.
The rgmanager package contains the Red Hat Resource Group Manager, which provides high availability for critical server applications in the event of system downtime.
Multiple insecure temporary file use flaws were discovered in rgmanager and various resource scripts run by rgmanager. A local attacker could use these flaws to overwrite an arbitrary file writable by the rgmanager process (i.e. user root) with the output of rgmanager or a resource agent via a symbolic link attack. (CVE-2008-6552)
This update also fixes the following bugs:
- clulog now accepts '-' as the first character in messages.
- if expire_time is 0, max_restarts is no longer ignored.
- the SAP resource agents included in the rgmanager package shipped with Red Hat Enterprise Linux 5.3 were outdated. This update includes the most recent SAP resource agents and, consequently, improves SAP failover support.
- empty PID files no longer cause resource start failures.
- recovery policy of type 'restart' now works properly when using a resource based on ra-skelet.sh.
- samba.sh has been updated to kill the PID listed in the proper PID file.
- handling of the '-F' option has been improved to fix issues causing rgmanager to crash if no members of a restricted failover domain were online.
- the number of simultaneous status checks can now be limited to prevent load spikes.
- forking and cloning during status checks has been optimized to reduce load spikes.
- rg_test no longer hangs when run with large cluster configuration files.
- when rgmanager is used with a restricted failover domain it will no longer occasionally segfault when some nodes are offline during a failover event.
- virtual machine guests no longer restart after a cluster.conf update.
- nfsclient.sh no longer leaves temporary files after running.
- extra checks from the Oracle agents have been removed.
- vm.sh now uses libvirt.
- users can now define an explicit service processing order when central_processing is enabled.
- virtual machine guests can no longer start on 2 nodes at the same time.
- in some cases a successfully migrated virtual machine guest could restart when the cluster.conf file was updated.
- incorrect reporting of a service being started when it was not started has been addressed.
As well, this update adds the following enhancements:
- a startup_wait option has been added to the MySQL resource agent.
- services can now be prioritized.
- rgmanager now checks to see if it has been killed by the OOM killer and if so, reboots the node.
Users of rgmanager are advised to upgrade to this updated package, which resolves these issues and adds these enhancements.
