Right now, no mediation is performed on requests received via NFS RPC's, so the first bit of the work is to provide for that mediation based on current credentials. The second bit is to find useful sources of label data for those credentials -- that might include host mapping tables, additional NFS RPCs, packet labels, etc. The mediation element falls out easily once you have some of the NFS credential fixes we have in the MAC tree, and shouldn't be hard. Then the question of where the labels come from and how to integrate the policies are raised, and I think some experimentation is called for. > And what about packet labeling - it's still desired feature for > trustedbsd/6.0-current? Yes. It could be we get it in for 5.2, though. Both improvements in IPSEC integration, and CIPSO are highly desirable features.
