21 tristate "Transformation user configuration interface"
24 Support for Transformation(XFRM) user configuration interface
25 like IPsec used by native Linux tools.
30 tristate "Transformation virtual interface"
31 depends on XFRM && IPV6
33 This provides a virtual interface to route IPsec traffic.
37 config XFRM_SUB_POLICY
38 bool "Transformation sub policy support"
41 Support sub policy for developers. By using sub policy with main
42 one, two policies can be applied to the same packet at once.
43 Policy which lives shorter time in kernel should be a sub.
48 bool "Transformation migrate database"
51 A feature to update locator(s) of a given IPsec security
52 association dynamically. This feature is required, for
53 instance, in a Mobile IPv6 environment with IPsec configuration
54 where mobile nodes change their attachment point to the Internet.
58 config XFRM_STATISTICS
59 bool "Transformation statistics"
60 depends on XFRM && PROC_FS
62 This statistics is not a SNMP/MIB specification but shows
63 statistics about transformation error (or almost error) factor
64 at packet processing for developer.
75 tristate "PF_KEY sockets"
78 PF_KEYv2 socket family, compatible to KAME ones.
79 They are required if you are going to use IPsec tools ported
82 Say Y unless you know what you are doing.
84 config NET_KEY_MIGRATE
89 Add a PF_KEY MIGRATE message to PF_KEYv2 socket family.
90 The PF_KEY MIGRATE message is used to dynamically update
91 locator(s) of a given IPsec security association.
92 This feature is required, for instance, in a Mobile IPv6
93 environment with IPsec configuration where mobile nodes
94 change their attachment point to the Internet. Detail
