1.108.2. RHBA-2011:0495: openais bug fix update

An updated openais package that fixes various bugs is now available for Red Hat Enterprise Linux 5.

The Application Interface Specification (AIS) is an API and a set of policies for developing applications that maintain services during faults. The OpenAIS Standards Based Cluster Framework is an OSI-certified implementation of the Service Availability Forum AIS. The openais package contains the openais executable, OpenAIS service handlers, default configuration files and an init script.

This update fixes for the following bugs:

* When a system limit for semaphores or shared memory was exceeded on SysV, the openais client sometimes went into a loop. With this update, the openais client handles the situation properly, and no longer enters an infinite loop when either of these limits is exceeded. (BZ#694180)

* When the OpenAIS limit for open files was exceeded, the openais executable terminated unexpectedly. With this update, if the limit is reached, the published server listening socket is withdrawn and the connection closes without causing any crashes. (BZ#694181)

* Previously, if a token was lost in the recovery state, the openais executable sometimes accepted a commit token with old ring ID information. This resulted in an unexpected termination. This bug has been fixed and lost tokens are now handled properly. (BZ#694182).

* When the ring ID file for a processor was less then 8 bytes long, totemsrp terminated unexpectedly. Now, OpenAIS always creates fresh ring ID file data when an incorrect number of bytes are read from the ring ID. (BZ#694183)

All users of openais are advised to upgrade to this updated package, which fixes these bugs.
