net: sched: fix skb->protocol use in case of accelerated vlan path

2015-01-13T22:51:08+00:00

tc code implicitly considers skb->protocol even in case of accelerated vlan paths and expects vlan protocol type here. However, on rx path, if the vlan header was already stripped, skb->protocol contains value of next header. Similar situation is on tx path. So for skbs that use skb->vlan_tci for tagging, use skb->vlan_proto instead. Reported-by: Jamal Hadi Salim Signed-off-by: Jiri Pirko Acked-by: Jamal Hadi Salim Signed-off-by: David S. Miller

net: sched: implement qstat helper routines

2014-09-30T05:02:26+00:00

This adds helpers to manipulate qstats logic and replaces locations that touch the counters directly. This simplifies future patches to push qstats onto per cpu counters. Signed-off-by: John Fastabend Signed-off-by: David S. Miller

net: rcu-ify tcf_proto

2014-09-13T16:30:25+00:00

rcu'ify tcf_proto this allows calling tc_classify() without holding any locks. Updaters are protected by RTNL. This patch prepares the core net_sched infrastracture for running the classifier/action chains without holding the qdisc lock however it does nothing to ensure cls_xxx and act_xxx types also work without locking. Additional patches are required to address the fall out. Signed-off-by: John Fastabend Acked-by: Eric Dumazet Signed-off-by: David S. Miller

sch_dsmark: use correct func name in print messages

2013-12-31T18:50:57+00:00

In dsmark_drop(), the function name printed by pr_debug is "dsmark_reset", correct it to "dsmark_drop" by using __func__ . BTW, replace the other function names with __func__ . Signed-off-by: Yang Yingliang Signed-off-by: David S. Miller

net_sched: replace pr_warning with pr_warn

2013-12-31T18:50:56+00:00

net_sched: remove unnecessary parentheses while return

2013-12-11T03:44:51+00:00

return is not a function, parentheses are not required. Signed-off-by: Yang Yingliang Signed-off-by: David S. Miller

net: sched: factorize code (qdisc_drop())

2012-05-04T15:50:05+00:00

Use qdisc_drop() helper where possible. Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

pkt_sched: Stop using NLA_PUT*().

2012-04-01T22:11:37+00:00

These macros contain a hidden goto, and are thus extremely error prone and make code hard to audit. Signed-off-by: David S. Miller

net_sched: accurate bytes/packets stats/rates

2011-01-21T07:31:33+00:00

In commit 44b8288308ac9d (net_sched: pfifo_head_drop problem), we fixed a problem with pfifo_head drops that incorrectly decreased sch->bstats.bytes and sch->bstats.packets Several qdiscs (CHOKe, SFQ, pfifo_head, ...) are able to drop a previously enqueued packet, and bstats cannot be changed, so bstats/rates are not accurate (over estimated) This patch changes the qdisc_bstats updates to be done at dequeue() time instead of enqueue() time. bstats counters no longer account for dropped frames, and rates are more correct, since enqueue() bursts dont have effect on dequeue() rate.
