The resource-agents package contains a set of scripts to interface with several services to operate in a High Availability environment for both Pacemaker and rgmanager service managers.

It was discovered that certain resource agent scripts set the LD_LIBRARY_PATH environment variable to an insecure value containing empty path elements. A local user able to trick a user running those scripts to run them while working from an attacker-writable directory could use this flaw to escalate their privileges via a specially crafted dynamic library. (CVE-2010-3389)

This update also fixes the following bugs :

  • When using the Sybase database and the ASEHAagent resource in the cluster.conf file, it was not possible to run more than one ASEHAagent per Sybase installation.
    Consequently, a second ASEHA (Sybase Adaptive Server Enterprise (ASE) with the High Availability Option) agent could not be run. This bug has been fixed and it is now possible to use two ASEHA agents using the same Sybase installation.

  • The s/lang scripts, which implement internal functionality for the rgmanager package, while the central_processing option is in use, were included in the wrong package. Now, the rgmanager and resource-agents packages require each other for installation to prevent problems when they are used separately.

  • Previously, the oracledb.sh script was using the ‘shutdown abort’ command as the first attempt to shut down a database. With this update, oracledb.sh first attempts a graceful shutdown via the ‘shutdown immediate’ command before forcing the shutdown.

  • Previously, when setting up a service on a cluster with a shared IP resource and an Apache resource, the generated httpd.conf file contained a bug in the line describing the shared IP address (the ‘Listen’ line).
    Now, the Apache resource agent generates the ‘Listen’ line properly.

  • If a high-availability (HA) cluster service was defined with an Apache resource and was named with two words, such as ‘kickstart httpd’, the service never started because it could not find a directory with the space character in its name escaped. Now, Apache resources work properly if a name contains a space as described above.

  • When inheritance was used in the cluster.conf file, a bug in the /usr/share/cluster/nfsclient.sh file prevented it from monitoring NFS exports properly.
    Consequently, monitoring of NFS exports to NFS clients resulted in an endless loop. This bug has been fixed and the monitoring now works as expected.

  • Previously, the postgres-8 resource agent did not detect when a PostgreSQL server failed to start. This bug has been fixed and postgres-8 now works as expected in the described scenario.

  • When using the Pacemaker resource manager, the fs.sh resource agent reported an error condition, if called with the ‘monitor’ parameter and the referenced device did not exist. Consequently, the error condition prevented the resource from being started. Now, fs.sh returns the proper response code in the described scenario, thus fixing this bug.

  • Previously, numerous RGManager resource agents returned incorrect response codes when coupled with the Pacemaker resource manager. Now, the agents have been updated to work with Pacemaker properly.

This update also adds the following enhancement :

  • With this update, when the network is removed from a node using the netfs.sh resource agent, it now recovers faster than previously.

As well, this update upgrades the resource-agents package to upstream version 3.9.2, which provides a number of bug fixes and enhancements over the previous version.

All users of resource-agents are advised to upgrade to this updated package, which corrects these issues and adds these enhancements.
