Modified files:
sys/kern sysv_msg.c sysv_sem.c sysv_shm.c
Log:
- Use td_ucred for jail checks.
- Move jail checks and some other checks involving constants and stack
variables out from under Giant. This isn't perfectly safe atm because
jail_sysvipc_allowed is read w/o a lock meaning that its value could be
stale. This global variable will soon become a per-jail flag, however,
at which time it will either not need a lock or will use the prison lock.
