RHBA-2014:1510 - Bug Fix Advisory

Topic

Updated keepalived packages that fix several bugs and add various enhancements
are now available for Red Hat Enterprise Linux 6.

Description

The keepalived packages provide simple and robust facilities for load-balancing
and high-availability. The load-balancing framework relies on the well-know and
widely used Linux Virtual Server kernel module providing Layer4 network
load-balancing. The keepalived daemon implements a set of health checkers to
load-balanced server pools according their state. The keepalived daemon also
implements the Virtual Router Redundancy Protocol (VRRP), allowing router or
director failover to achieve high availability.

The keepalived packages have been upgraded to upstream version 1.2.13, which
provides a number of bug fixes and enhancements over the previous version.
(BZ#1052380, BZ#1077201)

This update also fixes the following bugs:

• Previously, the VRRP alert emails sent by the keepalived daemon did not

contain the "to" header, which complicated filtering and sorting such messages
by email software. With this update, keepalived has been modified to include the
"to" header into email alerts as expected. (BZ#967641)

• Previously, when keepalived compared the local primary IP address with another

IP address, these two addresses had different byte-ordering. Consequently,
multiple routers were created in a master state. With this update, the local
primary IP address is converted to network byte order before the comparison,
thus fixing this bug. (BZ#1007575)

Users of keepalived are advised to upgrade to these updated packages, which fix
these bugs and add these enhancements.
