    sys/kern             subr_mbuf.c 
  Log:
  Introduce support for Mandatory Access Control and extensible
  kernel access control.
  
  Invoke the necessary MAC entry points to maintain labels on header
  mbufs.  In particular, invoke entry points during the two mbuf
  header allocation cases, and the mbuf freeing case.  Pass the "how"
  argument at allocation time to the MAC framework so that it can
  determine if it is permitted to block (as with policy modules),
  and permit the initialization entry point to fail if it needs to
  allocate memory but is not permitted to, failing the mbuf
  allocation.
