iedowse 2001/11/09 15:58:07 PST Modified files: 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.
