This is a note to let you know that I've just added the patch titled netfilter: nfnetlink_queue: drop bogus WARN_ON to the 6.9-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: netfilter-nfnetlink_queue-drop-bogus-warn_on.patch and it can be found in the queue-6.9 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit a41ccb5bac485aafe516011a22511c2fa34dcf13 Author: Florian Westphal <fw@xxxxxxxxx> Date: Tue Jul 9 02:02:26 2024 +0200 netfilter: nfnetlink_queue: drop bogus WARN_ON [ 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.
