RHBA-2011:1631 - netcf bug fix and enhancement update

Synopsis

netcf bug fix and enhancement update

Type/Severity

Bug Fix Advisory (none)

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.

Solution

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