# # XFRM configuration # config XFRM bool depends on NET select GRO_CELLS config XFRM_OFFLOAD bool depends on XFRM config XFRM_ALGO tristate select XFRM select CRYPTO config XFRM_USER tristate "Transformation user configuration interface" depends on INET select XFRM_ALGO ---help--- Support for Transformation(XFRM) user configuration interface like IPsec used by native Linux tools. If unsure, say Y. config XFRM_SUB_POLICY bool "Transformation sub policy support" depends on XFRM ---help--- Support sub policy for developers. By using sub policy with main one, two policies can be applied to the same packet at once. Policy which lives shorter time in kernel should be a sub. If unsure, say N. config XFRM_MIGRATE bool "Transformation migrate database" depends on XFRM ---help--- A feature to update locator(s) of a given IPsec security association dynamically. This feature is required, for instance, in a Mobile IPv6 environment with IPsec configuration where mobile nodes change their attachment point to the Internet. If unsure, say N. config XFRM_STATISTICS bool "Transformation statistics" depends on INET && XFRM && PROC_FS ---help--- This statistics is not a SNMP/MIB specification but shows statistics about transformation error (or almost error) factor at packet processing for developer. If unsure, say N. config XFRM_IPCOMP tristate select XFRM_ALGO select CRYPTO select CRYPTO_DEFLATE config NET_KEY tristate "PF_KEY sockets" select XFRM_ALGO ---help--- PF_KEYv2 socket family, compatible to KAME ones. They are required if you are going to use IPsec tools ported from KAME. Say Y unless you know what you are doing. config NET_KEY_MIGRATE bool "PF_KEY MIGRATE" depends on NET_KEY select XFRM_MIGRATE ---help--- Add a PF_KEY MIGRATE message to PF_KEYv2 socket family. The PF_KEY MIGRATE message is used to dynamically update locator(s) of a given IPsec security association. This feature is required, for instance, in a Mobile IPv6 environment with IPsec configuration where mobile nodes change their attachment point to the Internet. Detail information can be found in the internet-draft <draft-sugimoto-mip6-pfkey-migrate>. If unsure, say N.
