Fix commit: bdbfbec5 Do more sanity checks when accepting socket addresses in routing messages from user land. Inspect length field early in rtm_xaddrs(). Strings must be NUL terminated. The socket address type and length depend on the routing message type. Currently checks are not super strict to avoid too much user land fallout.
