RHBA-2009:0074 - Bug Fix Advisory

Topic

Updated openais package that resolves various defects is now available.

Description

This package contains the openais executive, openais service
handlers, default configuration files and init script.

This updated openais package applies the following bug fixes:

• Resolve defect where a user with inappropriate permissions could access

aisexec and cause it to segfault.

• Resolve defect where a missing message would cause the checkpoint service

to segfault the aisexec process under rare circumstances.

• Resolve defect where messages were not fully recovered in some rare cases

in the recovery state.

• Resolve defect where CPG users could face a priority inversion and

overload of the IPC system resulting in disconnection of the CPG service.

• Resolve defect where the IPC dispatch thread is flooded with signals

during overload conditions.

• Resolve defect where an aborted synchronization resulted in lost checkpoints.
• Resolve defect in how system call is used in ais-keygen.
• Resolve defect where synchronization of the global checkpoint ID didn't

occur properly.

• Resolve assertion which occurs when checkpoint close occurs during

overload conditions.

• Resolve assertion that occurs when thousands of checkpoints expire at

about the same time.

• Make lib_exit_fn work properly in overload conditions.
• Remove deadlock that occurs in IPC system under overload.

All users of openais should upgrade to this updated package, which
resolves these issues.
