RHBA-2012:0800 - fence-virt bug fix update

Synopsis

fence-virt bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated fence-virt packages that fix four bugs are now available for Red Hat Enterprise Linux 6.

Description

The fence-virt packages provide a fencing agent for virtual machines as well as a host agent which processes fencing requests.

This update fixes the following bugs:

• Prior to this update, the libvirt-qpid plug-in did not handle exceptions correctly. As a consequence, the fence_virtd daemon could unexpectedly terminate with a segmentation fault if the connection to the specified qpid daemon failed. This update modifies the exception handling. Now, the fencing operation works as expected. (BZ#753974)

• Prior to this update, the hashing utility sha_verify did not handle errors correctly when a key file could not be read. As a consequence, the fence_virtd daemon could unexpectedly terminate with a segmentation fault when receiving a fencing request if fence_virtd failed to read the specified key file during startup. This update modifies the error handling if a key file cannot be read. Now, fence_virtd no longer terminates under these conditions. (BZ#758392)

• Prior to this update, the XML example for serial mode in the fence_virt.conf(5) man page contained an incorrect closing tag. This update corrects this tag. (BZ#761215)

• Prior to this update, the libvirt-qpid plug-in was linked directly against the qpid libraries instead of only the qmfv2 library. As a consequence, newer versions of the qpid libraries could not be used with the libvirt-qpid plug-in. This update no longer links against the qpid libraries directly. Now, also newer qpid libraries can be used with libvirt-qpid. (BZ#806949)

• Prior to this update, the fence_virtd.conf manpage and the fence_virtd.conf generator incorrectly stated that by default, fence_virtd listened on all network interfaces. Both have been amended to state that by default, fence_virtd listens on the default network interface. (BZ#809101)

All users of fence-virt are advised to upgrade to these updated packages, which fix these bugs.
