[NET_SCHED]: Kill CONFIG_NET_CLS_POLICE

2007-07-15T07:03:05Z

The NET_CLS_ACT option is now a full replacement for NET_CLS_POLICE, remove the old code. The config option will be kept around to select the equivalent NET_CLS_ACT options for a short time to allow easier upgrades. Signed-off-by: Patrick McHardy Signed-off-by: David S. Miller

[NET_SCHED]: act_api: qdisc internal reclassify support

2007-07-15T07:02:31Z

The behaviour of NET_CLS_POLICE for TC_POLICE_RECLASSIFY was to return it to the qdisc, which could handle it internally or ignore it. With NET_CLS_ACT however, tc_classify starts over at the first classifier and never returns it to the qdisc. This makes it impossible to support qdisc-internal reclassification, which in turn makes it impossible to remove the old NET_CLS_POLICE code without breaking compatibility since we have two qdiscs (CBQ and ATM) that support this. This patch adds a tc_classify_compat function that handles reclassification the old way and changes CBQ and ATM to use it. This again is of course not fully backwards compatible with the previous NET_CLS_ACT behaviour. Unfortunately there is no way to fully maintain compatibility *and* support qdisc internal reclassification with NET_CLS_ACT, but this seems like the better choice over keeping the two incompatible options around forever.

[NET_SCHED]: Fix endless loops caused by inaccurate qlen counters (part 1)

2006-12-03T05:31:42Z

There are multiple problems related to qlen adjustment that can lead to an upper qdisc getting out of sync with the real number of packets queued, leading to endless dequeueing attempts by the upper layer code. All qdiscs must maintain an accurate q.qlen counter. There are basically two groups of operations affecting the qlen: operations that propagate down the tree (enqueue, dequeue, requeue, drop, reset) beginning at the root qdisc and operations only affecting a subtree or single qdisc (change, graft, delete class). Since qlen changes during operations from the second group don't propagate to ancestor qdiscs, their qlen values become desynchronized. This patch adds a function to propagate qlen changes up the qdisc tree, optionally calling a callback function to perform qdisc-internal maintenance when the child qdisc becomes empty. The follow-up patches will convert all qdiscs to use this function where necessary. Noticed by Timo Steinbach . Signed-off-by: Patrick McHardy Signed-off-by: David S. Miller

[NET_SCHED]: Set parent classid in default qdiscs

Adds qdisc_alloc() to share code between qdisc_create() and qdisc_create_dflt(). Hides the qdisc alignment behind macros and makes use of them. Signed-off-by: Thomas Graf Signed-off-by: David S. Miller
