- 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."
- To compile this protocol support as a module, choose M here: the
- module will be called sctp.
- If in doubt, say N.

- config SCTP_DBG_MSG
- bool "SCTP: Debug messages"
- 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 PROC_FS
- 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. This debug information can be viewed by
- 'cat /proc/net/sctp/sctp_dbg_objcnt'
- If unsure, say N

- prompt "SCTP: Cookie HMAC Algorithm"
- default SCTP_HMAC_MD5
- 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"
- help
- Enable the use of HMAC-SHA1 during association establishment. It
- is advised to use either HMAC-MD5 or HMAC-SHA1.
