RHBA-2013:0824 - corosync bug fix update

Synopsis

corosync bug fix update

Type/Severity

Bug Fix Advisory

Topic

An updated corosync package that fixes several bugs is now available for Red Hat Enterprise Linux 6.

Description

The Corosync packages provide the Corosync Cluster Engine and C Application Programming Interfaces (APIs) for Red Hat Enterprise Linux cluster software.

This update fixes the following bug:

  • When running applications which used the Corosync IPC library, some messages in the dispatch() function were lost or duplicated. This update properly checks the return values of the dispatch_put() function, returns the correct remaining bytes in the IPC ring buffer, and ensures that the IPC client is correctly informed about the real number of messages in the ring buffer. Now, messages in the dispatch() function are no longer lost or duplicated. (BZ#929101)

Users of corosync are advised to upgrade to these updated packages, which fix this bug.

Solution

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

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/knowledge/articles/11258
