[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.
