This patch for SELinux (applies to 2.6.10-rc2 or 2.6.10-rc2-mm2) fixes a bug in the mapping of socket types to security classes and ensures that Unix seqpacket sockets are mapped to an appropriate security class. The Unix stream security class is re-used in this case as it has the same permission checking applied as for seqpacket. Please apply.
