1.138.1. RHBA-2009:1474: bug fix update
Note
This update has already been released (prior to the GA of this release) as errata RHBA-2009:1474
The Application Interface Specification (AIS) is an API and set of policies for developing applications that maintain service 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 executive, openais service handlers, default configuration files and init script.
This update addresses the following issue:
* an invalid assertion caused MTUs of 9000 bytes to generate a SIGABRT signal and dump core when inside totem running heavy loads. With this update, the assertion has been corrected (and the MTU increased to 10000 bytes). (BZ#521098)
All openais users should install this update which fixes this bug.
1.138.2. RHBA-2010:0180: bug fix update
Updated openais packages that fix several defects are now available for Red Hat Enterprise Linux 5.5.
The Open Application Interface Specification (OpenAIS) is an API and a set of policies for developing applications that maintain service during faults. The OpenAIS Standards-Based Cluster Framework is an OSI-certified implementation of the Service Availability Forum AIS. The openais packages contain the openais executive, openais service handlers, default configuration files, and init script.
This update addresses the following issues:
* Resolve a segfault if the ais group doesn't exist. Note the ais group is installed by the package but may be removed by the user later. This resolution prints an error in that condition. (BZ#509180)
* Properly shut down service engines when the INTR signal or QUIT signal is sent to the aisexec process. (BZ#526069)
* Resolve a race condition in the cpg service which could result in failures during recovery of cpg services. (BZ#474400)
* A random error code was returned by saCkptCheckpointOpen if the internal IPC operation failed. Now the proper SA_AIS_ERR_LIBRARY error code is returned in this condition. (BZ#520164)
* An invalid assertion caused MTUs of 9000 bytes to generate a SIGABRT signal and dump core when inside totem running heavy loads. With this update, the assertion has been corrected (and the MTU increased to 10000 bytes). (BZ#520012)
* Resolve a problem where checkpoint iteration and discovery can happen during synchronization of new data structures. This results in the GFS POSIX locking feature appearing to leave leftover locks on nodes that no longer exist. (BZ#515159)
* Resolve a stack overflow that results in a stack protector assertion. (BZ#525280)
* Resolve a defect when calling saClmTrackStart more then one time can trigger a segfault in library clients to the clm service. (BZ#529054)
* Resolve a defect where cpg can use a variable after it has been freed. (BZ#540267)
* Resolve a defect where the bindnetaddr does not follow the specifications outlined by the man pages for operation because it uses the interface's broadcast address instead of its local address for binding. (BZ#540490)
* Resolve a defect where originating 206 messages in the recovery phase triggers totem to block until a processor is stopped or started. (BZ#544680)
* Resolve a defect where a buffer overflow can occur in a string buffer used when the "debug: on" option is used in the configuration. (BZ#544682)
* Resolve a defect where an internal totem operating flag is not set properly. (BZ#545151)
* Resolve a defect where an invalid assertion in single-node operation can trigger an assertion. (BZ#547828)
* Resolve a defect where the IPC limit was 477k instead of 1MB as it should be. (BZ#515590)
* Resolve a defect where IPC would indicate the outbound ipc queue was empty when the IPC queue is fully consumed by data. (BZ#560313)
* Resolve a defect where errant code calls pthread_cond_wait in an atexit() handler, resulting in lockup of the aisexec daemon 1% of the time on shutdown. (BZ#566467)
All openais users should install this update, which fixes these bugs.
