[IPV6] MCAST: Ensure to check multicast listener(s).
In ip6_mc_input(), we need to check whether we have listener(s) for the packet. After commit ae7bf20a6316272acfcaef5d265b18aaa54b41e4, all packets for multicast destinations are delivered to upper layer if IFF_PROMISC or IFF_ALLMULTI is set. In fact, bug was rather ancient; the original (before the commit) intent of the dev->flags check was to skip the ipv6_chk_mcast_addr() call, assuming L2 filters packets appropriately, but it was even not true. Let's explicitly check our multicast list. Signed-off-by: YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org> Acked-by: David L Stevens <dlstevens@us.ibm.com> Signed-off-by: David S.
