2008-02-05	[NET_SCHED]: cls_flow: fix key mask validity check	Patrick McHardy	1	-2/+3
	Since we're using fls(), we need to check whether the value is non-zero first. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-02-05	[NET_SCHED]: Add #ifdef CONFIG_NET_EMATCH in net/sched/cls_flow.c (latest git broken build)	Rami Rosen	1	-2/+2
	The 2.6 latest git build was broken when using the following configuration options: CONFIG_NET_EMATCH=n CONFIG_NET_CLS_FLOW=y with the following error: net/sched/cls_flow.c: In function 'flow_dump': net/sched/cls_flow.c:598: error: 'struct tcf_ematch_tree' has no member named 'hdr' make[2]: * [net/sched/cls_flow.o] Error 1 make[1]: * [net/sched] Error 2 make: *** [net] Error 2 see the recent post by Li Zefan: http://www.spinics.net/lists/netdev/msg54434.html The reason for this crash is that struct tcf_ematch_tree (net/pkt_cls.h) is empty when CONFIG_NET_EMATCH is not defined. When CONFIG_NET_EMATCH is defined, the tcf_ematch_tree structure indeed holds a struct tcf_ematch_tree_hdr (hdr) as flow_dump() expects. This patch adds #ifdef CONFIG_NET_EMATCH in flow_dump to avoid this. Signed-off-by: Rami Rosen <ramirose@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-01-31	[NET_SCHED]: Add flow classifier	Patrick McHardy	1	-0/+660
	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.
