[XFRM]: BEET mode

2006-10-04T07:31:09Z

This patch introduces the BEET mode (Bound End-to-End Tunnel) with as specified by the ietf draft at the following link: http://www.ietf.org/internet-drafts/draft-nikander-esp-beet-mode-06.txt The patch provides only single family support (i.e. inner family = outer family).

[XFRM] STATE: Add a hook to find offset to be inserted header in outbound.

2006-09-22T22:06:36Z

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.

[XFRM]: Add XFRM_MODE_xxx for future use.

2006-09-22T22:05:15Z

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.

[CRYPTO] users: Use crypto_comp and crypto_has_*

This patch converts all users to use the new crypto_comp type and the crypto_has_* functions. Signed-off-by: Herbert Xu

[IPCOMP]: Fix truesize after decompression

2006-07-12T20:58:55Z

The truesize check has uncovered the fact that we forgot to update truesize after pskb_expand_head. Unfortunately pskb_expand_head can't update it for us because it's used in all sorts of different contexts, some of which would not allow truesize to be updated by itself. So the solution for now is to simply update it in IPComp. This patch also changes skb_put to __skb_put since we've just expanded tailroom by exactly that amount so we know it's there (but gcc does not). Signed-off-by: Herbert Xu Signed-off-by: David S.

[NET]: Clean up skb_linearize

2006-06-18T04:30:16Z

The linearisation operation doesn't need to be super-optimised. So we can replace __skb_linearize with __pskb_pull_tail which does the same thing but is more general. Also, most users of skb_linearize end up testing whether the skb is linear or not so it helps to make skb_linearize do just that. Some callers of skb_linearize also use it to copy cloned data, so it's useful to have a new function skb_linearize_cow to copy the data if it's either non-linear or cloned. Last but not least, I've removed the gfp argument since nobody uses it anymore. If it's ever needed we can easily add it back. Misc bugs fixed by this patch: * via-velocity error handling (also, no SG => no frags) Signed-off-by: Herbert Xu Signed-off-by: David S. Miller

[IPSEC] proto: Move transport mode input path into xfrm_mode_transport

2006-06-18T04:28:41Z

Now that we have xfrm_mode objects we can move the transport mode specific input decapsulation code into xfrm_mode_transport. This removes duplicate code as well as unnecessary header movement in case of tunnel mode SAs since we will discard the original IP header immediately. This also fixes a minor bug for transport-mode ESP where the IP payload length is set to the correct value minus the header length (with extension headers for IPv6). Of course the other neat thing is that we no longer have to allocate temporary buffers to hold the IP headers for ESP and IPComp. Signed-off-by: Herbert Xu Signed-off-by: David S. Miller
