[NETFILTER]: Drop conntrack reference when packet leaves IP
In the event a raw socket is created for sending purposes only, the creator never bothers to check the socket's receive queue. But we continue to add skbs to its queue until it fills up. Unfortunately, if ip_conntrack is loaded on the box, each skb we add to the queue potentially holds a reference to a conntrack. If the user attempts to unload ip_conntrack, we will spin around forever since the queued skbs are pinned. Signed-off-by: Patrick McHardy <> Signed-off-by: David S. Miller <>
