From 323a53c41292a0d7efc8748856c623324c8d7c21 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Wed, 5 Jun 2019 07:55:09 -0700 Subject: ipv6: tcp: enable flowlabel reflection in some RST packets When RST packets are sent because no socket could be found, it makes sense to use flowlabel_reflect sysctl to decide if a reflection of the flowlabel is requested. This extends commit 22b6722bfa59 ("ipv6: Add sysctl for per namespace flow label reflection"), for some TCP RST packets. In order to provide full control of this new feature, flowlabel_reflect becomes a bitmask. Signed-off-by: Eric Dumazet Signed-off-by: David S.
