  11        depends on INET && XFRM
  12        ---help---
  13          Support for Transformation(XFRM) user configuration interface
  14          like IPsec used by native Linux tools.

  16          If unsure, say Y.

  20        depends on XFRM && EXPERIMENTAL
  21        ---help---
  22          Support sub policy for developers. By using sub policy with main
  23          one, two policies can be applied to the same packet at once.
  24          Policy which lives shorter time in kernel should be a sub.

  29        bool "Transformation migrate database (EXPERIMENTAL)"
  30        depends on XFRM && EXPERIMENTAL
  31        ---help---
  32          A feature to update locator(s) of a given IPsec security
  33          association dynamically.  This feature is required, for
  34          instance, in a Mobile IPv6 environment with IPsec configuration
  35          where mobile nodes change their attachment point to the Internet.
  36
  37          If unsure, say N.

  40        bool "Transformation statistics (EXPERIMENTAL)"

  42        ---help---
  43          This statistics is not a SNMP/MIB specification but shows
  44          statistics about transformation error (or almost error) factor
  45          at packet processing for developer.
  46
  47          If unsure, say N.

  55config NET_KEY

  57        select XFRM
  58        ---help---
  59          PF_KEYv2 socket family, compatible to KAME ones.
  60          They are required if you are going to use IPsec tools ported
  61          from KAME.
  62
  63          Say Y unless you know what you are doing.
  64
  65config NET_KEY_MIGRATE
  66        bool "PF_KEY MIGRATE (EXPERIMENTAL)"
  67        depends on NET_KEY && EXPERIMENTAL
  68        select XFRM_MIGRATE
  69        ---help---
  70          Add a PF_KEY MIGRATE message to PF_KEYv2 socket family.
  71          The PF_KEY MIGRATE message is used to dynamically update
  72          locator(s) of a given IPsec security association.
  73          This feature is required, for instance, in a Mobile IPv6
  74          environment with IPsec configuration where mobile nodes
  75          change their attachment point to the Internet.  Detail
  76          information can be found in the internet-draft
  77          <draft-sugimoto-mip6-pfkey-migrate>.
