This is V2, this time as a small series since I followed Erics advice
to split this into smaller chunks, I hope this makes it easier to
review.
First patch adds inet_sk_transparent helper.
Second patch contains an if/else swap that I split from the
original TW_RST v1 one.
Third patch is the actual change without the superfluous sock_net change.
Thanks,
Florian

Avoids cluttering tcp_v4_send_reset when followup patch extends
it to deal with timewait sockets.

tcp_md5_do_lookup requires a full socket, so once we extend
_send_reset() to also accept timewait socket we would have to change
if (!sk && hash_location)
to something like
if ((!sk || !sk_fullsock(sk)) && hash_location) {
...
} else {
(sk && sk_fullsock(sk)) tcp_md5_do_lookup()
}
Switch the two branches: check if we have a socket first, then
fall back to a listener lookup if we saw a md5 option (hash_location).

Hannes points out that when we generate tcp reset for timewait sockets we
pretend we found no socket and pass NULL sk to tcp_vX_send_reset().
Make it cope with inet tw sockets and then provide tw sk.
This makes RSTs appear on correct interface when SO_BINDTODEVICE is used.
Packetdrill test case:
// want default route to be used, we rely on BINDTODEVICE
`ip route del 192.0.2.0/24 via 192.168.0.2 dev tun0`
0.000 socket(..., SOCK_STREAM, IPPROTO_TCP) = 3
// test case still works due to BINDTODEVICE
0.001 setsockopt(3, SOL_SOCKET, SO_BINDTODEVICE, "tun0", 4) = 0
0.100...0.200 connect(3, ..., ...) = 0
0.100 > S 0:0(0) <mss 1460,sackOK,nop,nop>
0.200 < S. 0:0(0) ack 1 win 32792 <mss 1460,sackOK,nop,nop>
0.200 > . 1:1(0) ack 1
0.210 close(3) = 0
0.210 > F. 1:1(0) ack 1 win 29200
0.300 < . 1:1(0) ack 2 win 46
// more data while in FIN_WAIT2, expect RST
1.300 < P. 1:1001(1000) ack 1 win 46
// fails without this change -- default route is used
1.301 > R 1:1(0) win 0

Changes since v1:
follow all of Erics suggestions, namely:
- drop unneeded special-casing of sock_net(), it handles TW sk just fine
- use new inet_sk_transparent() helper to reduce clutter
- tcp_v6_send_response also handles TW sockets, no need to set
TW sk to NULL
- split if/else md5 change to extra patch
