Stream Control Transmission Protocol
From RFC 2960 (http://www.ietf.org/rfc/rfc2960.txt)
"SCTP is a reliable transport protocol operating on top of a
connectionless packet network such as IP. It offers the following
services to its users:
-- acknowledged error-free non-duplicated transfer of user data,
-- data fragmentation to conform to discovered path MTU size,
-- sequenced delivery of user messages within multiple streams,
with an option for order-of-arrival delivery of individual user
messages,
-- optional bundling of multiple user messages into a single SCTP
packet, and
-- network-level fault tolerance through supporting of multi-
homing at either or both ends of an association."
This protocol support is also available as a module ( = code which
can be inserted in and removed from the running kernel whenever you
want). The module will be called sctp. If you want to compile it
as a module, say M here and read <file:Documentation/modules.txt>.
If in doubt, say N.
config SCTP_ADLER32
bool "SCTP: Use old checksum (Adler-32)"
depends on IP_SCTP
help
RFC2960 currently specifies the Adler-32 checksum algorithm for SCTP.
This has been deprecated and replaced by an algorithm now referred
to as crc32c.
If you say Y, this will use the Adler-32 algorithm, this might be
useful for interoperation with downlevel peers.
If unsure, say N.
config SCTP_DBG_MSG
bool "SCTP: Debug messages"
depends on IP_SCTP
help
If you say Y, this will enable verbose debugging messages.
If unsure, say N. However, if you are running into problems, use
this option to gather detailed trace information
config SCTP_DBG_OBJCNT
bool "SCTP: Debug object counts"
depends on IP_SCTP
help
If you say Y, this will enable debugging support for counting the
type of objects that are currently allocated. This is useful for
identifying memory leaks. If the /proc filesystem is enabled this
debug information can be viewed by
'cat /proc/net/sctp/sctp_dbg_objcnt'
If unsure, say N
choice
prompt "SCTP: Cookie HMAC Algorithm"
depends on IP_SCTP
help
HMAC algorithm to be used during association initialization. It
is strongly recommended to use HMAC-SHA1 or HMAC-MD5. See
configuration for Cryptographic API and enable those algorithms
to make usable by SCTP.
config SCTP_HMAC_NONE
bool "None"
help
Choosing this disables the use of an HMAC during association
establishment. It is advised to use either HMAC-MD5 or HMAC-SHA1.
config SCTP_HMAC_SHA1
bool "HMAC-SHA1" if CRYPTO_HMAC=y && CRYPTO_SHA1=y || CRYPTO_SHA1=m
help
Enable the use of HMAC-SHA1 during association establishment. It
is advised to use either HMAC-MD5 or HMAC-SHA1.
config SCTP_HMAC_MD5
bool "HMAC-MD5" if CRYPTO_HMAC=y && CRYPTO_MD5=y || CRYPTO_MD5=m
help
Enable the use of HMAC-MD5 during association establishment. It is
advised to use either HMAC-MD5 or HMAC-SHA1.
