sys/net : route.c
Log message:
Never cache a RTF_GATEWAY route as next hop for a gateway route.
This prevents rtentry loops when rt->rt_gwroute points to rt leading
to an infamous "rtentry leak" panic, easily triggered by dhclient(8)
trying to remove a route after resuming a machine.
This bug is at least 20 years old! 4.4BSD-Lite2 had a fix for it in
its X.25 output routine but apparently it never made it into OpenBSD.
