RHBA-2014:1510 - keepalived bug fix and enhancement update

Synopsis

keepalived bug fix and enhancement update

Type/Severity

Bug Fix Advisory (none)

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.
