- ppp: Fix race condition with queue start/stop
-
- Commit e675f0cc9a872fd152edc0c77acfed19bf28b81e ("ppp: Don't stop and
- restart queue on every TX packet") introduced a race condition which
- could leave the net queue stopped even when the channel is no longer
- busy. By calling netif_stop_queue() from ppp_start_xmit(), based on the
- return value from ppp_xmit_process() but *after* all the locks have been
- dropped, we could potentially do so *after* the channel has actually
- finished transmitting and attempted to re-wake the queue.
-
- Fix this by moving the netif_stop_queue() into ppp_xmit_process() under
- the xmit lock. I hadn't done this previously, because it gets called
- from other places than ppp_start_xmit(). But I now think it's the better
- option. The net queue *should* be stopped if the channel becomes
- congested due to writes from pppd, anyway.

- ppp: Don't stop and restart queue on every TX packet
-
- For every transmitted packet, ppp_start_xmit() will stop the netdev
- queue and then, if appropriate, restart it. This causes the TX softirq
- to run, entirely gratuitously.
-
- This is "only" a waste of CPU time in the normal case, but it's actively
- harmful when the PPP device is a TEQL slave — the wakeup will cause the
- offending device to receive the next TX packet from the TEQL queue, when
- it *should* have gone to the next slave in the list. We end up seeing
- large bursts of packets on just *one* slave device, rather than using
- the full available bandwidth over all slaves.
-
- This patch fixes the problem by *not* unconditionally stopping the queue
- in ppp_start_xmit(). It adds a return value from ppp_xmit_process()
- which indicates whether the queue should be stopped or not.
-
- It *doesn't* remove the call to netif_wake_queue() from
- ppp_xmit_process(), because other code paths (especially from
- ppp_output_wakeup()) need it there and it's messy to push it out to the
- other callers to do it based on the return value. So we leave it in
- place — it's a no-op in the case where the queue wasn't stopped, so it's
- harmless in the TX path.
