tcp: don't annotate mark on control socket from tcp_v6_send_response()
commit 92e55f4 upstream. Unlike ipv4, this control socket is shared by all cpus so we cannot use it as scratchpad area to annotate the mark that we pass to ip6_xmit(). Add a new parameter to ip6_xmit() to indicate the mark. The SCTP socket family caches the flowi6 structure in the sctp_transport structure, so we cannot use to carry the mark unless we later on reset it back, which I discarded since it looks ugly to me. Fixes: bf99b4d ("tcp: fix mark propagation with fwmark_reflect enabled") Suggested-by: Eric Dumazet <[email protected]> Signed-off-by: Pablo Neira Ayuso <[email protected]> Signed-off-by: David S.
