2008-10-08pkt_sched: Update qdisc requeue stats in dev_requeue_skb()Jarek Poplawski
After the last change of requeuing there is no info about such incidents in tc stats. This patch updates the counter, but we should consider this should differ from previous stats because of additional checks preventing to repeat this. On the other hand, previous stats didn't include requeuing of gso_segmented skbs. Signed-off-by: Jarek Poplawski <jarkao2@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-10-08tcp: fix length used for checksum in a resetIlpo Järvinen
While looking for some common code I came across difference in checksum calculation between tcp_v6_send_(reset|ack) I couldn't explain. I checked both v4 and v6 and found out that both seem to have the same "feature". I couldn't find anything in rfc nor anywhere else which would state that md5 option should be ignored like it was in case of reset so I came to a conclusion that this is probably a genuine bug. I suspect that addition of md5 just was fooled by the excessive copy-paste code in those functions and the reset part was never tested well enough to find out the problem.

2008-10-08netfilter: xtables: provide invoked family value to extensionsJan Engelhardt
By passing in the family through which extensions were invoked, a bit of data space can be reclaimed. The "family" member will be added to the parameter structures and the check functions be adjusted. Signed-off-by: Jan Engelhardt <jengelh@medozas.de> Signed-off-by: Patrick McHardy <kaber@trash.net>

2008-10-08netfilter: xtables: move extension arguments into compound structure (1/6)Jan Engelhardt
The function signatures for Xtables extensions have grown over time. It involves a lot of typing/replication, and also a bit of stack space even if they are not used. Realize an NFWS2008 idea and pack them into structs. The skb remains outside of the struct so gcc can continue to apply its optimizations. This patch does this for match extensions' match functions. A few ambiguities have also been addressed. The "offset" parameter for example has been renamed to "fragoff" (there are so many different offsets already) and "protoff" to "thoff" (there is more than just one protocol here, so clarify).

2008-10-08netfilter: iptables TPROXY targetKOVACS Krisztian
The TPROXY target implements redirection of non-local TCP/UDP traffic to local sockets. Additionally, it's possible to manipulate the packet mark if and only if a socket has been found. (We need this because we cannot use multiple targets in the same iptables rule.) Signed-off-by: KOVACS Krisztian <hidden@sch.bme.hu> Signed-off-by: Patrick McHardy <kaber@trash.net>

2008-10-08netfilter: iptables tproxy coreKOVACS Krisztian

2008-10-08netfilter: split netfilter IPv4 defragmentation into a separate moduleKOVACS Krisztian
Netfilter connection tracking requires all IPv4 packets to be defragmented. Both the socket match and the TPROXY target depend on this functionality, so this patch separates the Netfilter IPv4 defrag hooks into a separate module.

2008-10-08netfilter: enable netfilter in netnsAlexey Dobriyan
From kernel perspective, allow entrance in nf_hook_slow(). Stuff which uses nf_register_hook/nf_register_hooks, but otherwise not netns-ready: DECnet netfilter ipt_CLUSTERIP nf_nat_standalone.c together with XFRM (?) IPVS several individual match modules (like hashlimit) ctnetlink NOTRACK all sorts of queueing and reporting to userspace L3 and L4 protocol sysctls, bridge sysctls probably something else Anyway critical mass has been achieved, there is no reason to hide netfilter any longer. From userspace perspective, allow to manipulate all sorts of iptables/ip6tables/arptables rules. Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: Patrick McHardy <kaber@trash.net>
