  Modified files:
    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 !
