19 tristate "Transformation user configuration interface"
23 Support for Transformation(XFRM) user configuration interface
24 like IPsec used by native Linux tools.
29 tristate "Transformation virtual interface"
30 depends on XFRM && IPV6
32 This provides a virtual interface to route IPsec traffic.
36 config XFRM_SUB_POLICY
37 bool "Transformation sub policy support"
40 Support sub policy for developers. By using sub policy with main
41 one, two policies can be applied to the same packet at once.
42 Policy which lives shorter time in kernel should be a sub.
47 bool "Transformation migrate database"
50 A feature to update locator(s) of a given IPsec security
51 association dynamically. This feature is required, for
52 instance, in a Mobile IPv6 environment with IPsec configuration
53 where mobile nodes change their attachment point to the Internet.
57 config XFRM_STATISTICS
58 bool "Transformation statistics"
59 depends on INET && XFRM && PROC_FS
61 This statistics is not a SNMP/MIB specification but shows
62 statistics about transformation error (or almost error) factor
63 at packet processing for developer.
74 tristate "PF_KEY sockets"
77 PF_KEYv2 socket family, compatible to KAME ones.
78 They are required if you are going to use IPsec tools ported
81 Say Y unless you know what you are doing.
83 config NET_KEY_MIGRATE
88 Add a PF_KEY MIGRATE message to PF_KEYv2 socket family.
89 The PF_KEY MIGRATE message is used to dynamically update
90 locator(s) of a given IPsec security association.
91 This feature is required, for instance, in a Mobile IPv6
92 environment with IPsec configuration where mobile nodes
93 change their attachment point to the Internet. Detail
94 information can be found in the internet-draft
95 <draft-sugimoto-mip6-pfkey-migrate>.
