This is a note to let you know that I've just added the patch titled netfilter: nf_fwd_netdev: clear timestamp in forwarding path to the 5.8-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-nf_fwd_netdev-clear-timestamp-in-forwardin.patch and it can be found in the queue-5.8 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit f48b6e9853360b07c06a434b0486ed663028c39a Author: Pablo Neira Ayuso <pablo@xxxxxxxxxxxxx> Date: Wed Oct 21 12:55:52 2020 +0200 netfilter: nf_fwd_netdev: clear timestamp in forwarding path [ Upstream commit c77761c8a59405cb7aa44188b30fffe13fbdd02d ] Similar to 7980d2eabde8 ("ipvs: clear skb->tstamp in forwarding path"). fq qdisc requires tstamp to be cleared in forwarding path. Fixes: 8203e2d844d3 ("net: clear skb->tstamp in forwarding paths") Fixes: fb420d5d91c1 ("tcp/fq: move back to CLOCK_MONOTONIC") Fixes: 80b14dee2bea ("net: Add a new socket option for a future transmit time.")
