RHBA-2011:1631 - Bug Fix Advisory

Topic

Updated netcf packages that fix multiple bugs and add various enhancements are
now available for Red Hat Enterprise Linux 6.

Description

The netcf packages contain a library for modifying the network configuration of
a system. Network configuration is expressed in a platform-independent XML
format, which netcf translates into changes to the system's "native" network
configuration files.

The netcf packages have been upgraded to upstream version 0.1.9, which provides
a number of bug fixes and enhancements over the previous version.

As well, this update fixes the following bug:

• Prior to this update, certain interfaces associated configuration files in the

/etc/sysconfig/network-scripts/ directory, but no corresponding device in the
kernel. As a result, netcf returned an error status every time it was asked for
the current status of an interface it was unable to find in the kernel, so
management applications collected a large number of error log messages. With
this update, failures to find an interface in the kernel are now ignored.
(BZ#713286)

This update also adds the following enhancements:

• In this update, netcf has been modified to capture the stdout and stderr

output of ifup and ifdown, and, in the case of an error, forward that
information back to the management application, which used netcf to start or
stop an interface. This makes it easier to troubleshoot problems. (BZ#616060)

• Changes made to a host's network configuration by netcf (via netcf's API, or

the ncftool commands) immediately and permanently modify the host's
configuration files (in /etc/sysconfig/network-scripts/ifcfg-*). With this
update, new API/virsh commands have been added to enable saving the current
state of network configuration before any changes are made, and easily reverting
to that configuration if any problems are encountered. (BZ#708476)

All users are advised to updated to these updated packages, which fix these bugs
and add these enhancements.
