- ---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.

- ---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.
