We have local changes in the TrustedBSD development trees to extend all the structures in the kernel without modifying the ABI. We needed this to put labels in the various System V IPC object structures. We're not ready to merge them yet, but it will probably happen in the next month or so. If you'd like early access to the patch, we can drop you a copy. We'll merge it into the MAC tree in about a week.
