RHBA-2014:1475 - 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 several 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 the netcf library translates into changes to the system's "native" network configuration files.

The netcf package has been upgraded to upstream version 0.2.4, which provides a number of bug fixes and enhancements over the previous version. This includes a change ensuring that an interface with unplugged cable is not considered to be active. (BZ#851748)

This update also fixes the following bugs:

• The libvirtd service could terminate unexpectedly when retrieving a MAC address. This happened because the netcf code contained uninitialized data that could be accessed by libvirtd. With this update, netcf properly initializes this data and libvirtd no longer crashes in this case. (BZ#879055)

• Previously, netcf added an additional set of quotes to the value of the BONDING_OPTS parameter while attempting to create a bond interface. Consequently, the attempt failed with an error similar to the following:

Error creating interface: 'Could not create interface: internal error failed to create (start) interface bond0: failed to execute external program - Running 'ifup bond0' failed with exit code 1: ./network-functions: line 457: /sys/class/net/bond0/bonding/'mode: No such file or directory

With this update, additional quotes are no longer added to BONDING_OPTS and bonding devices can now be created as expected with this parameter specified. (BZ#1052156)

Users of netcf are advised to upgrade 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.

Note that after the update has been applied, the libvirtd service must be restarted before it will begin using the updated netcf library. This can be done with the following command:

service libvirtd restart

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/articles/11258
