REDHAT-BUG-1006509: Low severity oracle libvirt vulnerability
Upstream Commit 29fe5d7 (released in 1.1.1) introduced a latent problem for any caller of virSecurityManagerSetProcessLabel and where the domain already had a uid:gid label to be parsed. Such a setup would collect the list of supplementary groups during virSecurityManagerPreFork, but then ignores that information, and thus fails to call setgroups() to adjust the supplementary groups of the process.
