usr.sbin/ppp ncpaddr.c route.c
Log:
Be paranoid about non-zero netmasks being associated with INET addresses
of 0.0.0.0.
The OpenBSD PF_ROUTE/NET_RT_DUMP sysctl is sending back routes with
RTAX_NETMASK set, but the corresponding sockaddr being 4 zero bytes
(with an address family of zero). ppp was getting confused by this
and ending up interpreting it as a 0.0.0.0/32 routing table
destination and subsequently failing to do anything with the route.
Specifically, after this fix, ppp under OpenBSD can successfully
change and delete the default route again !
