libvirt bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated libvirt packages that fix multiple bugs are now available for Red Hat
Enterprise Linux 5.

Description

The libvirt library is a C API for managing and interacting with the
virtualization capabilities of Linux and other operating systems. In addition,
libvirt provides tools for remote management of virtualized systems. The libvirt
library also provides nwfilter support for fine-grained filtering of the network
traffic reaching guests managed by libvirt.

This update fixes the following bugs:

• Prior to this update, the automatic IPTables rule that allowed Trivial File
  Transfer Protocol (TFTP) traffic could cause the libvirt daemon (libvirtd) to
  report errors after upgrading the daemon. This update removes the rule after
  tftp was added. (BZ#676622)
  
• Prior to this update, the target tag that indicates which host is allowed to
  see the the list of disks to be exported to the guests was ignored and the disks
  were named in the order they appeared in the XML file instead. This update
  modifies the order of disks and controllers so that the target tag is no longer
  ignored. (BZ#719435)
  
• Prior to this update, the dclose() function invoked an already removed
  callback function if the thread local remained in the memory. As a consequence,
  libvirt terminated unexpectedly with a segmentation fault when unloading the
  libvirt.so provider. This update links libvirt with with the -z nodelete option
  to prevent the code from being removed from memory when calling dlclose().
  (BZ#735127)
  
• Prior to this update, the Coverity check contained several defects that could
  mask security driver failures, fail to configure the mac_filter, leak resources
  using domxml-from-native options. This update modifies the underlying code so
  that these defects no longer occur. (BZ#747514)
  
• Prior to this update, the QEMU driver could fail to find the user or group ID
  of the QEMU application on the system due to a programming error in the
  initialization code of libvirtd. As a result, libvirtd could fail to start. This
  update modifies the initialization code and libvirtd now works as expected.
  (BZ#771720)
  

All users of libvirt are advised to upgrade to these updated packages, which fix
these bugs.
