RHBA-2012:1153 - Bug Fix Advisory

Topic

Updated iproute packages that fix two bugs are now available for Red Hat
Enterprise Linux 5.

Description

The iproute packages provide networking utilities like ip and rtmon, which use
the advanced networking capabilities of the Linux kernel.

This update fixes the following bug:

• Prior to this update, the print_route() could, udner circumstances use the

wrong "hz" value. As a consequence, the "ip route show" option returned an
incorrect value for rto_min (minimum TCP retransmission timeout). This update
modifies the underlying code to identify the different "hz" values. Now, the
correct rto_min value is displayed. (BZ#738965)

• Prior to this update, the tc command-line utility generated a wrong filter

match for the IPv6 "priority", the resulting match did not reflect the IPv6
header field proper. This update modifies the underlying code to match the IPv6
"Priority" header as expected. (BZ#751285)

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

Solution

Before applying this update, make sure all previously-released errata relevant
to your system have been applied.
