  Modified files:
    sys/sys              ucred.h 
  Log:
  Introduce support for Mandatory Access Control and extensible kernel
  access control.
  
  Label process credentials, permitting security information to be
  maintained at the granularity of processes and cached credential
  objects.  cr_label follows the semantics of other entries in struct
  ucred: when a credential is exclusively referenced, it may be
  modified.  Otherwise, it must be treated as immutable.  As with
  other interesting entries in struct ucred, failing to use the
  documented credential management APIs (such as crcopy, crdup, ...)
  can result in data corruption or incorrect behavior.
