Robert Watson a96acd1ace Introduce a condition variable to avoid returning EBUSY when ... the MAC policy list is busy during a load or unload attempt. We assert no locks held during the cv wait, meaning we should be fairly deadlock-safe. Because of the cv model and busy count, it's possible for a cv waiter waiting for exclusive access to the policy list to be starved by active and long-lived access control/labeling events. For now, we accept that as a necessary tradeoff. Obtained from: TrustedBSD Project Sponsored by: DARPA, Network Associates Laboratories		2002-11-13 15:47:09 +00:00
