RHBA-2013:0050 - Bug Fix Advisory

Topic

Updated quagga packages that fix several bugs are now available for Red Hat
Enterprise Linux 5.

Description

The quagga packages contain Quagga, the free network-routing software suite that
manages TCP/IP based protocols. Quagga supports the BGP4, BGP4+, OSPFv2, OSPFv3,
RIPv1, RIPv2, and RIPng protocols, and is intended to be used as a Route Server
and Route Reflector.

This update fixes the following bugs:

• Previously, several function declarations were missing in the zebra.h header

file. As a consequence, a zebra server terminated unexpectedly with a
segmentation fault when commands, such as "show ip protocol", calling these
functions were issued on the zebra server. With this update, the missing
function declarations have been added and zebra servers no longer crash in this
scenario. (BZ#528583)

• Previously on system update, Quagga marked obsolete any other routing packages

that provide the same functionality as Quagga, such as the bird package that
provides a TCP/IP routing daemon. Consequently, such packages were removed from
the system. With this update, the quagga spec file has been modified so that it
no longer obsoletes other routing packages. (BZ#604620)

• Previously, Quagga init scripts did not locate PID files of Quagga daemons

correctly. Consequently, these PID files were not removed during service
shutdown. With this update, Quagga init scripts have been modified to locate the
respective PID files correctly and the PID files now no longer remain on the
system after the service is stopped. (BZ#508800)

• Previously, Quagga init scripts ignored the QCONFDIR variable specified in the

/etc/sysconfig/quagga file and used an explicit path to the configuration files
instead. This could cause problems if the location of the configuration changed.
This update modifies Quagga init scripts to use the QCONFDIR variable as
expected. (BZ#716324)

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