23 tristate "Transformation user configuration interface"
26 Support for Transformation(XFRM) user configuration interface
27 like IPsec used by native Linux tools.
31 config XFRM_USER_COMPAT
32 tristate "Compatible ABI support"
33 depends on XFRM_USER && COMPAT_FOR_U64_ALIGNMENT
34 select WANT_COMPAT_NETLINK_MESSAGES
36 Transformation(XFRM) user configuration interface like IPsec
37 used by compatible Linux applications.
42 tristate "Transformation virtual interface"
43 depends on XFRM && IPV6
45 This provides a virtual interface to route IPsec traffic.
49 config XFRM_SUB_POLICY
50 bool "Transformation sub policy support"
53 Support sub policy for developers. By using sub policy with main
54 one, two policies can be applied to the same packet at once.
55 Policy which lives shorter time in kernel should be a sub.
60 bool "Transformation migrate database"
63 A feature to update locator(s) of a given IPsec security
64 association dynamically. This feature is required, for
65 instance, in a Mobile IPv6 environment with IPsec configuration
66 where mobile nodes change their attachment point to the Internet.
70 config XFRM_STATISTICS
71 bool "Transformation statistics"
72 depends on XFRM && PROC_FS
74 This statistics is not a SNMP/MIB specification but shows
75 statistics about transformation error (or almost error) factor
76 at packet processing for developer.
80 # This option selects XFRM_ALGO along with the AH authentication algorithms that
81 # RFC 8221 lists as MUST be implemented.
89 # This option selects XFRM_ALGO along with the ESP encryption and authentication
90 # algorithms that RFC 8221 lists as MUST be implemented.

111 tristate "PF_KEY sockets"
114 PF_KEYv2 socket family, compatible to KAME ones.
115 They are required if you are going to use IPsec tools ported
118 Say Y unless you know what you are doing.
120 config NET_KEY_MIGRATE
121 bool "PF_KEY MIGRATE"
125 Add a PF_KEY MIGRATE message to PF_KEYv2 socket family.
126 The PF_KEY MIGRATE message is used to dynamically update
127 locator(s) of a given IPsec security association.
128 This feature is required, for instance, in a Mobile IPv6
129 environment with IPsec configuration where mobile nodes
130 change their attachment point to the Internet. Detail
