4.20-stable review patch. If anyone has any objections, please let me know.
------------------ From: Paolo Abeni <[email protected]> [ 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 <[email protected]> Signed-off-by: Paolo Abeni <[email protected]> Acked-by: Nikolay Aleksandrov <[email protected]> Acked-by: Roopa Prabhu <[email protected]> Reviewed-by: Eric Dumazet <[email protected]> Signed-off-by: David S.
