Vasily Averin 73d0f37ac4 cbq: incorrectly low bandwidth setting blocks limited traffic ... Mainstream commit f0f6ee1f70 ("cbq: incorrect processing of high limits") have side effect: if cbq bandwidth setting is less than real interface throughput non-limited traffic can delay limited traffic for a very long time. This happen because of q->now changes incorrectly in cbq_dequeue(): in described scenario L2T is much greater than real time delay, and q->now gets an extra boost for each transmitted packet. Accumulated boost prevents update q->now, and blocked class can wait very long time until (q->now >= cl->undertime) will be true again. To fix the problem the patch updates q->now on each cbq_update() call. L2T-related pre-modification q->now was moved to cbq_update(). My testing confirmed that it fixes the problem and did not discover any side-effects Fixes: f0f6ee1f70 ("cbq: incorrect processing of high limits") Signed-off-by: Vasily Averin <vvs@openvz.org> Signed-off-by: David S.
