pkt_sched: Add multiqueue scheduler support

2008-09-12T23:29:34Z

This patch is intended to add a qdisc to support the new tx multiqueue architecture by providing a band for each hardware queue. By doing this it is possible to support a different qdisc per physical hardware queue. This qdisc uses the skb->queue_mapping to select which band to place the traffic onto. It then uses a round robin w/ a check to see if the subqueue is stopped to determine which band to dequeue the packet from.

[NET_SCHED]: Add flow classifier

2008-02-01T03:28:36Z

Add new "flow" classifier, which is meant to extend the SFQ hashing capabilities without hard-coding new hash functions and also allows deterministic mappings of keys to classes, replacing some out of tree iptables patches like IPCLASSIFY (maps IPs to classes), IPMARK (maps IPs to marks, with fw filters to classes), ... Some examples: - Classic SFQ hash: tc filter add ... flow hash \ keys src,dst,proto,proto-src,proto-dst divisor 1024 - Classic SFQ hash, but using information from conntrack to work properly in combination with NAT: tc filter add ... flow hash \ keys nfct-src,nfct-dst,proto,nfct-proto-src,nfct-proto-dst divisor 1024 - Map destination IPs of 192.168.0.0/24 to classids 1-257: tc filter add ... flow map \ key dst addend -192.168.0.0 divisor 256 - alternatively: tc filter add ... flow map \ key dst and 0xff - similar, but reverse ordered: tc filter add ... flow map \ key dst and 0xff xor 0xff Perturbation is currently not supported because we can't reliable kill the timer on destruction.

[PKT_SCHED]: Add stateless NAT

2007-10-10T23:53:11Z

Stateless NAT is useful in controlled environments where restrictions are placed on through traffic such that we don't need connection tracking to correctly NAT protocol-specific data. In particular, this is of interest when the number of flows or the number of addresses being NATed is large, or if connection tracking information has to be replicated and where it is not practical to do so. Previously we had stateless NAT functionality which was integrated into the IPv4 routing subsystem. This was a great solution as long as the NAT worked on a subnet to subnet basis such that the number of NAT rules was relatively small. The reason is that for SNAT the routing based system had to perform a linear scan through the rules. If the number of rules is large then major renovations would have take place in the routing subsystem to make this practical. For the time being, the least intrusive way of achieving this is to use the u32 classifier written by Alexey Kuznetsov along with the actions infrastructure implemented by Jamal Hadi Salim. The following patch is an attempt at this problem by creating a new nat action that can be invoked from u32 hash tables which would allow large number of stateless NAT rules that can be used/updated in constant time. The actual NAT code is mostly based on the previous stateless NAT code written by Alexey. In future we might be able to utilise the protocol NAT code from netfilter to improve support for other protocols. Signed-off-by: Herbert Xu Signed-off-by: David S. Miller

[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]: Remove dead net/sched/Makefile entry for sch_hpfq.o.

[PKT_SCHED]: Make sch_fifo.o available when CONFIG_NET_SCHED is not set.

2006-12-03T05:21:43Z

Based on patch by Patrick McHardy. Add a new option, NET_SCH_FIFO, which provides a simple fifo qdisc without requiring CONFIG_NET_SCHED. The d80211 stack needs a generic fifo qdisc for WME. At present it uses net/d80211/fifo_qdisc.c which is functionally equivalent to sch_fifo.c. This patch will allow the d80211 stack to remove net/d80211/fifo_qdisc.c and use sch_fifo.c instead.

[PKT_SCHED]: Blackhole queueing discipline

2005-07-05T22:29:16Z

Useful in combination with classful qdiscs to drop or temporary disable certain flows, e.g. one could block specific ds flows with dsmark. Unlike the noop qdisc it can be controlled by the user and statistic accounting is done. Signed-off-by: Thomas Graf Signed-off-by: David S. Miller
