Hi, Could the patch below (already in Linus' git tree for 2.6.25) be added to the rawhide kernel? It is to support polyinstantiation by XACE/XSELinux. Gitweb: http://git.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=2e08c0c1c3977a5ddc88887dd3af1b26c433e9d0 Commit: 2e08c0c1c3977a5ddc88887dd3af1b26c433e9d0 Parent: 1996a10948e50e546dc2b64276723c0b64d3173b Author: Eamon Walsh <ewalsh@xxxxxxxxxxxxx> AuthorDate: Thu Jan 24 15:30:52 2008 -0500 Committer: James Morris <jmorris@xxxxxxxxx> CommitDate: Fri Jan 25 11:29:56 2008 +1100 selinux: make mls_compute_sid always polyinstantiate This patch removes the requirement that the new and related object types differ in order to polyinstantiate by MLS level. This allows MLS polyinstantiation to occur in the absence of explicit type_member rules or when the type has not changed. Potential users of this support include pam_namespace.so (directory polyinstantiation) and the SELinux X support (property polyinstantiation).
