[PATCH] Reworked patch for labels on user space messages
The below patch should be applied after the inode and ipc sid patches. This patch is a reworking of Tim's patch that has been updated to match the inode and ipc patches since its similar. [updated: > Stephen Smalley also wanted to change a variable from isec to tsec in the > user sid patch. ] Signed-off-by: Steve Grubb <sgrubb@redhat.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
