RHBA-2009:1104 - Bug Fix Advisory

Topic

Updated openais packages that fix various bugs are now available.

Description

The openais packages provide the core infrastructure used by Red Hat
Cluster Suite and GFS.

This update fixes the following bugs:

• The CFG library, which is used to enable redundant ring, does not

function properly.

• The CPG service, which is used throughout the cluster software, can

sometimes segfault under certain loads.

• On ppc architectures, the IPC system can segfault because of how va_args

and unions operate on these platforms.

• The totempg subsystem in openais can sometimes throw away a message,

which can result in cluster failure.

• The IPC system contains a problem with the CPG service. The problem

causes the wrong error code to be returned when the library user has
insufficient permissions (regression).

• A race condition can cause the CPG service to have unexpected behavior

(regression).

• Configuration changes in the CPG service could be delivered out of order

(regression).

Users should upgrade to these updated packages, which resolve these issues.

Solution

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.

This update is available via Red Hat Network. Details on how to use
