[TCP]: Do not use inet->id of global tcp_socket when sending RST.
The problem is in ip_push_pending_frames(), which uses: if (!df) { __ip_select_ident(iph, &rt->u.dst, 0); } else { iph->id = htons(inet->id++); } instead of ip_select_ident(). Right now I think the code is a nonsense. Most likely, I copied it from old ip_build_xmit(), where it was really special, we had to decide whether to generate unique ID when generating the first (well, the last) fragment. In ip_push_pending_frames() it does not make sense, it should use plain ip_select_ident() instead. Signed-off-by: Alexey Kuznetsov <kuznet@ms2.inr.ac.ru> Signed-off-by: David S.
