[NET_SCHED]: Convert packet schedulers from rtnetlink to new netlink API

2008-01-28T23:11:10Z

Convert packet schedulers to use the netlink API. Unfortunately a gradual conversion is not possible without breaking compilation in the middle or adding lots of casts, so this patch converts them all in one step. The patch has been mostly generated automatically with some minor edits to at least allow seperate conversion of classifiers and actions. Signed-off-by: Patrick McHardy Signed-off-by: David S.

[NET]: Move Qdisc_class_ops and Qdisc_ops in appropriate sections.

2008-01-28T22:53:58Z

Qdisc_class_ops are const, and Qdisc_ops are mostly read. Using "const" and "__read_mostly" qualifiers helps to reduce false sharing. Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

[NET]: Clone the sk_buff 'iif' field in __skb_clone()

2008-01-09T07:30:17Z

Both NetLabel and SELinux (other LSMs may grow to use it as well) rely on the 'iif' field to determine the receiving network interface of inbound packets. Unfortunately, at present this field is not preserved across a skb clone operation which can lead to garbage values if the cloned skb is sent back through the network stack. This patch corrects this problem by properly copying the 'iif' field in __skb_clone() and removing the 'iif' field assignment from skb_act_clone() since it is no longer needed. Also, while we are here, put the assignments in the same order as the offsets to reduce cacheline bounces. Signed-off-by: Paul Moore Signed-off-by: David S. Miller

[NET_CLS_ACT]: Introduce skb_act_clone

2007-10-26T09:47:23Z

Reworked skb_clone looks uglier with the single ifdef CONFIG_NET_CLS_ACT This patch introduces skb_act_clone which will replace skb_clone in tc actions Signed-off-by: Jamal Hadi Salim Signed-off-by: David S. Miller

[NET_SCHED]: Making rate table lookups more flexible.

2007-10-10T23:49:20Z

This is done in order to, add support to changing the rate table to use the upper-boundry L2T (length to time) value. Currently we use the lower-boundry, which result in under-estimating the actual bandwidth usage. Extend the tc_ratespec struct, with two parameters: 1) "cell_align" that allow adjusting the alignment of the rate table. 2) "overhead" that allow adding a packet overhead before the lookup.

[NET_SCHED]: Cleanup L2T macros and handle oversized packets

2007-10-10T23:49:20Z

Change L2T (length to time) macros, in all rate based schedulers, to call a common function qdisc_l2t() that does the rate table lookup. This function handles if the packet size lookup is larger than the rate table, which often occurs with TSO enabled.

[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.
