RHBA-2011:0854 - Bug Fix Advisory

Topic

Updated corosync packages that fix several bugs are now available for Red Hat
Enterprise Linux 6 Extended Update Support.

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 bugs:

• When the corosync server terminated unexpectedly, if it was connected to

corosync clients, a shared memory leak occurred. This bug has been fixed and no
memory leaks occur in the described scenario. (BZ#696735)

• When a ring ID file was smaller than 8 bytes, the corosync server terminated

unexpectedly. With this update, if no proper ring ID file can be loaded, the
corosync server creates one and no crash will occur. (BZ#696734)

• During the recovery phase, the corosync server sometimes terminated

unexpectedly. As a consequence, a network token was lost and new configuration
had to be created. This bug has been fixed and the corosync server no longer
crashes in the described scenario. (BZ#696733)

• In rare circumstances involving multiple running nodes, the corosync server

terminated unexpectedly during shut down. This bug has been fixed and the
corosync server no longer crashes. (BZ#696732)

• When inconsistent cluster.conf files with different versions were used among

nodes, a memory leak occurred in the corosync server during the configuration
reload. This bug has been fixed and the configuration reload via the cman_tool
no longer causes memory leaks. (BZ#681258)

All users of corosync are advised to upgrade to these updated packages, which
fix these bugs.
