    sys/kern             subr_prf.c 
  Log:
  Properly sanity-check the old msgbuf structure before we accept it
  as being valid. Previously only the magic number and the virtual
  address were checked, but it makes little sense to require that
  the virtual address is the same (the message buffer is located at
  the end of physical memory), and checks on the msg_bufx and msg_bufr
  indices were missing.
