From 183144815e34369b97b8efbee7f524388c71ae1f Mon Sep 17 00:00:00 2001 From: Paolo Abeni Date: Tue, 8 Jan 2019 18:45:05 +0100 Subject: [PATCH] net: clear skb->tstamp in bridge forwarding path [ Upstream commit 41d1c8839e5f8cb781cc635f12791decee8271b7 ] Matteo reported forwarding issues inside the linux bridge, if the enslaved interfaces use the fq qdisc. Similar to commit 8203e2d844d3 ("net: clear skb->tstamp in forwarding paths"), we need to clear the tstamp field in the bridge forwarding path. Fixes: 80b14dee2bea ("net: Add a new socket option for a future transmit time.") Fixes: fb420d5d91c1 ("tcp/fq: move back to CLOCK_MONOTONIC") Reported-and-tested-by: Matteo Croce Signed-off-by: Paolo Abeni Acked-by: Nikolay Aleksandrov Acked-by: Roopa Prabhu Reviewed-by: Eric Dumazet Signed-off-by: David S.
