2006-09-22[IPSEC]: output mode to take an xfrm state as input paramJamal Hadi Salim
Expose IPSEC modes output path to take an xfrm state as input param. This makes it consistent with the input mode processing (which already takes the xfrm state as a param). Signed-off-by: Jamal Hadi Salim <hadi@cyberus.ca> Signed-off-by: David S. Miller <davem@davemloft.net>
2006-09-22[XFRM] IPV6: Update outbound state timestamp for each sending.Masahide NAKAMURA
With this patch transformation state is updated last used time for each sending. Xtime is used for it like other state lifetime expiration. Mobile IPv6 enabled nodes will want to know traffic status of each binding (e.g. judgement to request binding refresh by correspondent node, or to keep home/care-of nonce alive by mobile node). The last used timestamp is an important hint about it. Based on MIPL2 kernel patch.

2006-09-22[XFRM] STATE: Add a hook to find offset to be inserted header in outbound.Masahide NAKAMURA
On current kernel, ip6_find_1stfragopt() is used by IPv6 IPsec to find offset to be inserted header in outbound for transport mode. (BTW, no usage may be needed for IPv4 case.) Mobile IPv6 requires another logic for routing header and destination options header respectively. This patch is common platform for the offset and adopts it to IPsec. Based on MIPL2 kernel patch.

2006-09-22[XFRM]: Add XFRM_MODE_xxx for future use.Masahide NAKAMURA
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. Based on MIPL2 kernel patch.

2006-09-22[NET]: Replace CHECKSUM_HW by CHECKSUM_PARTIAL/CHECKSUM_COMPLETEPatrick McHardy
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). Patch originally from Herbert Xu, updated by myself for 2.6.18-rc3. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>

2006-07-08[NET] gso: Add skb_is_gsoHerbert Xu
This patch adds the wrapper function skb_is_gso which can be used instead of directly testing skb_shinfo(skb)->gso_size. This makes things a little nicer and allows us to change the primary key for indicating whether an skb is GSO (if we ever want to do that).

2006-06-23[IPSEC]: Handle GSO packetsHerbert Xu
This patch segments GSO packets received by the IPsec stack. This can happen when a NIC driver injects GSO packets into the stack which are then forwarded to another host. The primary application of this is going to be Xen where its backend driver may inject GSO packets into dom0. Of course this also can be used by other virtualisation schemes such as VMWare or UML since the tap device could be modified to inject GSO packets received through splice.

2006-06-17[IPSEC] xfrm: Abstract out encapsulation modesHerbert Xu
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.

2006-01-07[NETFILTER]: Fix xfrm lookup in ip_route_me_harder/ip6_route_me_harderPatrick McHardy
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>
2006-01-07[XFRM]: Netfilter IPsec output hooksPatrick McHardy
Call netfilter hooks before IPsec transforms. Packets visit the FORWARD/LOCAL_OUT and POST_ROUTING hook before the first encapsulation and the LOCAL_OUT and POST_ROUTING hook before each following tunnel mode transform. Patch from Herbert Xu <herbert@gondor.apana.org.au>: Move the loop from dst_output into xfrm4_output/xfrm6_output since they're the only ones who need to it. xfrm{4,6}_output_one() processes the first SA all subsequent transport mode SAs and is called in a loop that calls the netfilter hooks between each two calls. In order to avoid the tail call issue, I've added the inline function nf_hook which is nf_hook_slow plus the empty list check. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
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!
