Hi all,

For example, suppose ping is using a SOCK_RAW socket for ICMP messages. When receiving ping replies, in __raw_v4_lookup(), sk->sk_bound_dev_if is 3 (dummy1), but dif (skb_rtable(skb)->rt_iif) says 2 (dummy0), so the raw_sk_bound_dev_eq() check fails. Similar things happen in ping_lookup() for SOCK_ICMP sockets.
^^^^^^^^^ I actually meant "SOCK_DGRAM". Will fix in v2 soon. Sorry about it.
Thanks, Peilin Ye
