[ Upstream commit 8203e2d844d34af247a151d8ebd68553a6e91785 ] Sergey reported that forwarding was no longer working if fq packet scheduler was used. This is caused by the recent switch to EDT model, since incoming packets might have been timestamped by __net_timestamp() __net_timestamp() uses ktime_get_real(), while fq expects packets using CLOCK_MONOTONIC base. The fix is to clear skb->tstamp in forwarding paths. Fixes: 80b14dee ("net: Add a new socket option for a future transmit time.") Fixes: fb420d5d91c1 ("tcp/fq: move back to CLOCK_MONOTONIC") Signed-off-by: NEric Dumazet <edumazet@google.com> Reported-by: NSergey Matyukevich <geomatsi@gmail.com> Tested-by: NSergey Matyukevich <geomatsi@gmail.com> Signed-off-by: NDavid S.
