6 tristate "The SCTP Protocol"
8 depends on IPV6 || IPV6=n
14 Stream Control Transmission Protocol
16 From RFC 2960 <http://www.ietf.org/rfc/rfc2960.txt>.
18 "SCTP is a reliable transport protocol operating on top of a
19 connectionless packet network such as IP. It offers the following
20 services to its users:
22 -- acknowledged error-free non-duplicated transfer of user data,
23 -- data fragmentation to conform to discovered path MTU size,
24 -- sequenced delivery of user messages within multiple streams,
25 with an option for order-of-arrival delivery of individual user
27 -- optional bundling of multiple user messages into a single SCTP
29 -- network-level fault tolerance through supporting of multi-
30 homing at either or both ends of an association."
32 To compile this protocol support as a module, choose M here: the
33 module will be called sctp. Debug messages are handeled by the
34 kernel's dynamic debugging framework.
41 tristate "SCTP: Association probing"
42 depends on PROC_FS && KPROBES
44 This module allows for capturing the changes to SCTP association
45 state in response to incoming packets. It is used for debugging
46 SCTP congestion control algorithms. If you don't understand
47 what was just said, you don't need it: say N.
49 To compile this code as a module, choose M here: the
50 module will be called sctp_probe.
53 bool "SCTP: Debug transactions"
55 If you say Y, this will enable transaction debugging, visible
56 from the kernel's dynamic debugging framework.
58 If unsure, say N. However, if you are running into problems, use
59 this option to gather outqueue trace information.
61 config SCTP_DBG_OBJCNT
62 bool "SCTP: Debug object counts"
65 If you say Y, this will enable debugging support for counting the
66 type of objects that are currently allocated. This is useful for
67 identifying memory leaks. This debug information can be viewed by
68 'cat /proc/net/sctp/sctp_dbg_objcnt'
72 prompt "Default SCTP cookie HMAC encoding"
73 default SCTP_DEFAULT_COOKIE_HMAC_MD5
75 This option sets the default sctp cookie hmac algorithm
76 when in doubt select 'md5'
78 config SCTP_DEFAULT_COOKIE_HMAC_MD5
79 bool "Enable optional MD5 hmac cookie generation"
81 Enable optional MD5 hmac based SCTP cookie generation
82 select SCTP_COOKIE_HMAC_MD5

85 bool "Enable optional SHA1 hmac cookie generation"

90 config SCTP_DEFAULT_COOKIE_HMAC_NONE
91 bool "Use no hmac alg in SCTP cookie generation"
93 Use no hmac algorithm in SCTP cookie generation
97 config SCTP_COOKIE_HMAC_MD5
98 bool "Enable optional MD5 hmac cookie generation"
100 Enable optional MD5 hmac based SCTP cookie generation
101 select CRYPTO_HMAC if SCTP_COOKIE_HMAC_MD5
102 select CRYPTO_MD5 if SCTP_COOKIE_HMAC_MD5
104 config SCTP_COOKIE_HMAC_SHA1
105 bool "Enable optional SHA1 hmac cookie generation"
107 Enable optional SHA1 hmac based SCTP cookie generation
108 select CRYPTO_HMAC if SCTP_COOKIE_HMAC_SHA1
109 select CRYPTO_SHA1 if SCTP_COOKIE_HMAC_SHA1
