* [SK_BUFF]: Introduce ipv6_hdr(), remove skb->nh.ipv6hArnaldo Carvalho de Melo2007-04-251-2/+2
| | | | | | | | | | 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}.

* [SK_BUFF]: Introduce skb_network_header()Arnaldo Carvalho de Melo2007-04-251-3/+3
| | | | | | | | | For the places where we need a pointer to the network header, it is still legal to touch skb->nh.raw directly if just adding to, subtracting from or setting it to another layer header.

* [IPSEC]: changing API of xfrm6_tunnel_registerKazunori MIYAZAWA2007-02-131-1/+2
| | | | | | | | | | | This patch changes xfrm6_tunnel register and deregister interface to prepare for solving the conflict of device tunnels with inter address family IPsec tunnel. There is no device which conflicts with IPv4 over IPv6 IPsec tunnel. Signed-off-by: Kazunori MIYAZAWA <miyazawa@linux-ipv6.org> Signed-off-by: David S. Miller <davem@davemloft.net>

* [XFRM] STATE: Common receive function for route optimization extension headers.Masahide NAKAMURA2006-09-221-0/+108
| | | | | | | | | | | | | XFRM_STATE_WILDRECV flag is introduced; the last resort state is set it and receives packet which is not route optimized but uses such extension headers i.e. Mobile IPv6 signaling (binding update and acknowledgement). A node enabled Mobile IPv6 adds the state. Based on MIPL2 kernel patch.

* [XFRM]: Add XFRM_MODE_xxx for future use.Masahide NAKAMURA2006-09-221-1/+1
| | | | | | | | | | | | | Transformation mode is used as either IPsec transport or tunnel. It is required to add two more items, route optimization and inbound trigger for Mobile IPv6.

* [IPSEC] xfrm: Abstract out encapsulation modesHerbert Xu2006-06-171-26/+3
| | | | | | | | | | | | | | This patch adds the structure xfrm_mode. It is meant to represent the operations carried out by transport/tunnel modes. By doing this we allow additional encapsulation modes to be added without clogging up the xfrm_input/xfrm_output paths. Candidate modes include 4-to-6 tunnel mode, 6-to-4 tunnel mode, and BEET modes.

* [IPSEC]: Kill unused decap state structureHerbert Xu2006-04-011-4/+5

* [IPSEC]: Kill unused decap state argumentHerbert Xu2006-04-011-1/+1
| | | | | | | | | | | | | | This patch removes the decap_state argument from the xfrm input hook. Previously this function allowed the input hook to share state with the post_input hook. The latter has since been removed. The only purpose for it now is to check the encap type. However, it is easier and better to move the encap type check to the generic xfrm_rcv function. This allows us to get rid of the decap state argument altogether. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
* [INET]: Introduce tunnel4/tunnel6Herbert Xu2006-03-281-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Basically this patch moves the generic tunnel protocol stuff out of xfrm4_tunnel/xfrm6_tunnel and moves it into the new files of tunnel4.c and tunnel6 respectively. The reason for this is that the problem that Hugo uncovered is only the tip of the iceberg. The real problem is that when we removed the dependency of ipip on xfrm4_tunnel we didn't really consider the module case at all. For instance, as it is it's possible to build both ipip and xfrm4_tunnel as modules and if the latter is loaded then ipip simply won't load. After considering the alternatives I've decided that the best way out of this is to restore the dependency of ipip on the non-xfrm-specific part of xfrm4_tunnel. This is acceptable IMHO because the intention of the removal was really to be able to use ipip without the xfrm subsystem. This is still preserved by this patch. So now both ipip/xfrm4_tunnel depend on the new tunnel4.c which handles the arbitration between the two. The order of processing is determined by a simple integer which ensures that ipip gets processed before xfrm4_tunnel. The situation for ICMP handling is a little bit more complicated since we may not have enough information to determine who it's for. It's not a big deal at the moment since the xfrm ICMP handlers are basically no-ops. In future we can deal with this when we look at ICMP caching in general. The user-visible change to this is the removal of the TUNNEL Kconfig prompts. This makes sense because it can only be used through IPCOMP as it stands. The addition of the new modules shouldn't introduce any problems since module dependency will cause them to be loaded. Oh and I also turned some unnecessary pskb's in IPv6 related to this patch to skb's. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
* [IPV4/6]: Netfilter IPsec input hooksPatrick McHardy2006-01-071-0/+13
| | | | | | | | | | When the innermost transform uses transport mode the decapsulated packet is not visible to netfilter. Pass the packet through the PRE_ROUTING and LOCAL_IN hooks again before handing it to upper layer protocols to make netfilter-visibility symetrical to the output path.

* [IPV6]: Move nextheader offset to the IP6CBPatrick McHardy2006-01-071-4/+4
| | | | | | | | | | Move nextheader offset to the IP6CB to make it possible to pass a packet to ip6_input_finish multiple times and have it skip already parsed headers. As a nice side effect this gets rid of the manual hopopts skipping in ip6_input_finish. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-161-0/+150
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
