RHBA-2015:0542 - Bug Fix Advisory

Topic

An updated keepalived package that fixes several bugs and adds various enhancements is now available for Red Hat Enterprise Linux 7.

Description

Keepalived provides simple and robust facilities for load balancing and high availability. The load balancing framework relies on the well-known and widely used Linux Virtual Server (IPVS) kernel module providing layer-4 (transport layer) load balancing. Keepalived implements a set of checkers to dynamically and adaptively maintain and manage a load-balanced server pool according their health. Keepalived also implements the Virtual Router Redundancy Protocol (VRRPv2) to achieve high availability with director failover.

The keepalived package has been upgraded to upstream version 1.2.13, which provides a number of bug fixes and enhancements over the previous version. (BZ#1111716)

This update also fixes the following bug:

• This update adds the description of the -x or --snmp option that enables the Simple Network Management Protocol (SNMP) subsystem to the keepalived manual page. (BZ#1085535)

In addition, this update adds the following enhancement:

• With this update, the /usr/libexec/keepalived directory is automatically created and labeled with sufficient SELinux privileges. This directory is reserved for custom scripts created by users. Currently there are no scripts shipped directly with the keepalived package. (BZ#1158114)

Users of keepalived are advised to upgrade to this updated package, which fixes these bugs and adds these enhancements.
