-Subject: tcp: fix mark propagation with fwmark_reflect enabled
-
-From: Pau Espin Pedrol <pespin.shar@gmail.com>
-
-commit bf99b4ded5f8a4767dbb9d180626f06c51f9881f upstream.
-
-Otherwise, RST packets generated by the TCP stack for non-existing
-sockets always have mark 0.
-The mark from the original packet is assigned to the netns_ipv4/6
-socket used to send the response so that it can get copied into the
-response skb when the socket sends it.
-
-Fixes: e110861f8609 ("net: add a sysctl to reflect the fwmark on replies")
