RHBA-2011:1690 - Bug Fix Advisory

Topic

An updated iproute package that fixes various bugs is now available for Red Hat
Enterprise Linux 6.

Description

The iproute package contains networking utilities (ip and rtmon, for example)
which are designed to use the advanced networking capabilities of the Linux
kernel.

This updated iproute package includes fixes for the following bugs:

• Prior to this update, the "ip" utility lacked the "mode" parameter support for

macvtap devices. As a consequence affected users could not create macvtap
devices in "bridge" or "private" modes. With this update the "ip" utility now
fully supports macvtap devices along with the "mode" parameter and its options,
"bridge", "private", and "vepa" (default). As a result users can now utilize
macvtap functionality via the iproute package. (BZ#692867)

• Prior to this update, the "ip" tool lacked the "passthru" mode parameter

support for macvtap and macvlan devices. Consequently users could not create
macvtap and macvlan devices in "passthru" mode. The "ip" tool now fully supports
macvtap and macvlan devices along with the "mode" parameter and its options,
"bridge", "private", "passthru", and "vepa" (default). As a result users can now
utilize "passthru" mode as part of macvtap and macvlan functionality via the
iproute package. (BZ#693878)

• Prior to this update, the "tc" utility ignored GRED (Generalized RED) queue

options. Consequently "tc" users could not configure certain GRED queue related
parameters. With this update the "tc" utility no longer accidentally overwrites
the user specified options. As a result "tc" users can now reliably define all
GRED parameters. (BZ#709652)

All users of iproute are advised to upgrade to this updated package, which fixes
these bugs.
