8.62. haproxy

Updated haproxy packages that fix several bugs and add various enhancements are now available for Red Hat Enterprise Linux 6.
The haproxy packages provide a reliable, high-performance network load balancer for TCP and HTTP-based applications. It is particularly suited for web sites crawling under very high loads while needing persistence or Layer7 processing.


The haproxy packages have been upgraded to upstream version 1.4.24, which provides a number of bug fixes and enhancements over the previous version. (BZ#947987)

Bug Fix

Previously, the setuid() and setgid() functions did not work properly. As a consequence, the HAProxy load balancer failed to drop supplementary groups correctly after attempting to drop root privileges. The behavior of the functions has been modified, and HAProxy now drops all supplementary groups as expected.


With this update, support for TPROXY has been added to the haproxy packages. TPROXY simplifies management tasks of clients behind proxy firewalls. Also, transparent proxying makes the presence of the proxy invisible to the user.
Users of haproxy are advised to upgrade to these updated packages, which fix these bugs and add these enhancements.
