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 HAVE_EFFICIENT_UNALIGNED_ACCESS
35 select WANT_COMPAT_NETLINK_MESSAGES
37 Transformation(XFRM) user configuration interface like IPsec
38 used by compatible Linux applications.
43 tristate "Transformation virtual interface"
44 depends on XFRM && IPV6
46 This provides a virtual interface to route IPsec traffic.
50 config XFRM_SUB_POLICY
51 bool "Transformation sub policy support"
54 Support sub policy for developers. By using sub policy with main
55 one, two policies can be applied to the same packet at once.
56 Policy which lives shorter time in kernel should be a sub.
61 bool "Transformation migrate database"
64 A feature to update locator(s) of a given IPsec security
65 association dynamically. This feature is required, for
66 instance, in a Mobile IPv6 environment with IPsec configuration
67 where mobile nodes change their attachment point to the Internet.
71 config XFRM_STATISTICS
72 bool "Transformation statistics"
73 depends on XFRM && PROC_FS
75 This statistics is not a SNMP/MIB specification but shows
76 statistics about transformation error (or almost error) factor
77 at packet processing for developer.
81 # This option selects XFRM_ALGO along with the AH authentication algorithms that
82 # RFC 8221 lists as MUST be implemented.
90 # This option selects XFRM_ALGO along with the ESP encryption and authentication
91 # algorithms that RFC 8221 lists as MUST be implemented.

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