Subject: PRU_PERRADDR in uipc_usrreq.c
Index: sys/uipc_usrreq.c 4.3BSD

Description:
	In sys/uipc_usrreq.c, in the case PRU_PEERADDR, "m" was used
	instead of "nam" when copying the peer address.
Repeat-By:
	It crashes the system.  Trust us.
Fix:
	Apply the following context diff to sys/uipc_usrreq.c

*** uipc_usrreq.c.old	Fri May  8 14:05:11 1987
--- uipc_usrreq.c.new	Fri May  8 14:06:19 1987
