SVN rev 196932 on 2009-09-07 16:00:33Z by syrinx
When joining a multicast group, the inp_lookup_mcast_ifp call
does a KASSERT that the group address is multicast, so the
check if this is indeed true and eventually return a EINVAL if not,
should be done before calling inp_lookup_mcast_ifp. This fixes a kernel
crash when calling setsockopt (sock, IPPROTO_IP, IP_ADD_MEMBERSHIP,...)
with invalid group address.
