* [NET_SCHED]: Add flow classifierPatrick McHardy2008-01-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [NET_SCHED]: sch_ingress: remove netfilter supportPatrick McHardy2008-01-31
| | | | | | | | | | | | | | Since the old policer code is gone, TC actions are needed for policing. The ingress qdisc can get packets directly from netif_receive_skb() in case TC actions are enabled or through netfilter otherwise, but since without TC actions there is no policer the only thing it actually does is count packets. Remove the netfilter support and always require TC actions. Signed-off-by: Patrick McHardy <kaber@trash.net> Acked-by: Jamal Hadi Salim <hadi@cyberus.ca> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | 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.

* [NET_SCHED]: sch_ingress: remove useless printkPatrick McHardy2008-01-28
| | | | | | | | | | | | The printk about ingress qdisc registration error can't be triggered under normal circumstances.
