Excellent patch Alex !

Two minor coding style problems in this part :

Correct indentation, and one empty line after variable declaration :

	if (!relax && reuse && sk2->sk_reuse &&
	    sk2->sk_state != TCP_LISTEN) {
		const __be32 sk2_rcv_saddr = sk_rcv_saddr(sk2);

		if (!sk2_rcv_saddr || !sk_rcv_saddr(sk) ||
		    sk2_rcv_saddr == sk_rcv_saddr(sk))
			break;
	}



if (condition_one ||
    condition_two) {
	foo();

instead of

if (condition_on ||
	condition_two)
	foo();
