* [IPSEC]: IPv4 over IPv6 IPsec tunnelMiika Komu2007-02-081-10/+32
| | | | | | | | | This is the patch to support IPv4 over IPv6 IPsec. Signed-off-by: Miika Komu <miika@iki.fi> Signed-off-by: Diego Beltrami <Diego.Beltrami@hiit.fi> Signed-off-by: Kazunori Miyazawa <miyazawa@linux-ipv6.org> Signed-off-by: David S. Miller <davem@davemloft.net>
* [IPSEC]: output mode to take an xfrm state as input paramJamal Hadi Salim2006-09-221-2/+1
| | | | | | | | | 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>
* [IPSEC] xfrm: Abstract out encapsulation modesHerbert Xu2006-06-171-0/+121
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.
