Re: [PATCH net-next] net: bail on sock_wfree, sock_rfree when we have a TCP_TIMEWAIT sk

If we early-demux bind a TCP_TIMEWAIT socket to an skb and then orphan it
(as we need to do in the ipvs forwarding case), sock_wfree and sock_rfree
are going to reach into the inet_timewait_sock and mess with fields that
don't exist.

If we're forwarding, we should not find a local socket, period.

We should only match sockets for locally destined packets.

So I'd say that the state in which you say this can occur is illegal.
