2008-04-14[NETFILTER]: Add partial checksum validation helperPatrick McHardy1-7/+35
Move the UDP-Lite conntrack checksum validation to a generic helper similar to nf_checksum() and make it fall back to nf_checksum() in case the full packet is to be checksummed and hardware checksums are available. This is to be used by DCCP conntrack, which also needs to verify partial checksums. Signed-off-by: Patrick McHardy <kaber@trash.net>
2008-03-05[NETNS][IPV6] route6 - add netns parameter to ip6_route_outputDaniel Lezcano1-2/+2
Add an netns parameter to ip6_route_output. That will allow to access to the right routing table for outgoing traffic. Signed-off-by: Daniel Lezcano <dlezcano@fr.ibm.com> Signed-off-by: Benjamin Thery <benjamin.thery@bull.net> Signed-off-by: David S. Miller <davem@davemloft.net>

2008-01-28[NETFILTER]: nf_queue: move list_head/skb/id to struct nf_infoPatrick McHardy1-6/+8
Move common fields for queue management to struct nf_info and rename it to struct nf_queue_entry. The avoids one allocation/free per packet and simplifies the code a bit. Alternatively we could add some private room at the tail, but since all current users use identical structs this seems easier. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

2008-01-28[NETFILTER]: nf_ct_h323: remove ipv6 module dependencyPatrick McHardy1-0/+7
nf_conntrack_h323 needs ip6_route_output for the call forwarding filter. Add a ->route function to nf_afinfo and use that to avoid pulling in the ipv6 module. Fix the #ifdef for the IPv6 code while I'm at it - the IPv6 support is only needed when IPv6 conntrack is enabled. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-01-28[NETFILTER]: Introduce NF_INET_ hook valuesPatrick McHardy1-3/+3
The IPv4 and IPv6 hook values are identical, yet some code tries to figure out the "correct" value by looking at the address family. Introduce NF_INET_* values for both IPv4 and IPv6. The old values are kept in a #ifndef __KERNEL__ section for userspace compatibility.

2007-10-15[NETFILTER]: Replace sk_buff ** with sk_buff *Herbert Xu1-3/+3

2007-04-25[SK_BUFF]: Introduce ipv6_hdr(), remove skb->nh.ipv6hArnaldo Carvalho de Melo1-4/+4
Now the skb->nh union has just one member, .raw, i.e. it is just like the skb->mac union, strange, no? I'm just leaving it like that till the transport layer is done with, when we'll rename skb->mac.raw to skb->mac_header (or ->mac_header_offset?), ditto for ->{h,nh}.

2006-09-22[NET]: Replace CHECKSUM_HW by CHECKSUM_PARTIAL/CHECKSUM_COMPLETEPatrick McHardy1-1/+1
Replace CHECKSUM_HW by CHECKSUM_PARTIAL (for outgoing packets, whose checksum still needs to be completed) and CHECKSUM_COMPLETE (for incoming packets, device supplied full checksum).

2006-04-09[NETFILTER]: Add address family specific checksum helpersPatrick McHardy1-0/+34

2006-01-07[NETFILTER]: Fix xfrm lookup in ip_route_me_harder/ip6_route_me_harderPatrick McHardy1-1/+8
ip_route_me_harder doesn't use the port numbers of the xfrm lookup and uses ip_route_input for non-local addresses which doesn't do a xfrm lookup, ip6_route_me_harder doesn't do a xfrm lookup at all. Use xfrm_decode_session and do the lookup manually, make sure both only do the lookup if the packet hasn't been transformed already. Makeing sure the lookup only happens once needs a new field in the IP6CB, which exceeds the size of skb->cb. The size of skb->cb is increased to 48b. Apparently the IPv6 mobile extensions need some more room anyway. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
