6.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Florian Westphal <fw@xxxxxxxxx>
[ Upstream commit 631a4b3ddc7831b20442c59c28b0476d0704c9af ]
Happens when rules get flushed/deleted while packet is out, so remove
this WARN_ON.
This WARN exists in one form or another since v4.14, no need to backport
this to older releases, hence use a more recent fixes tag.
Fixes: 3f8019688894 ("netfilter: move nf_reinject into nfnetlink_queue modules")
Reported-by: kernel test robot <oliver.sang@xxxxxxxxx>
Closes: https://lore.kernel.org/oe-lkp/202407081453.11ac0f63-lkp@xxxxxxxxx
