How to configure the Linux kernel/net/sctp

Howto configure the Linux kernel / net / sctp


 * SCTP configuration
 * SCTP configuration

SCTP Configuration (EXPERIMENTAL)

 * depends on INET && EXPERIMENTAL


 * Option: IP_SCTP
 * Kernel Versions: 2.6.15.6 ...
 * (on/off/module) The SCTP Protocol (EXPERIMENTAL)
 * depends on IPV6 || IPV6=n
 * select CRYPTO if SCTP_HMAC_SHA1 || SCTP_HMAC_MD5
 * select CRYPTO_HMAC if SCTP_HMAC_SHA1 || SCTP_HMAC_MD5
 * select CRYPTO_SHA1 if SCTP_HMAC_SHA1
 * select CRYPTO_MD5 if SCTP_HMAC_MD5
 * Stream Control Transmission Protocol
 * From RFC 2960 &lt;http://www.ietf.org/rfc/rfc2960.txt&gt;.
 * 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.


 * Option: SCTP_DBG_MSG
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) SCTP: Debug messages
 * depends on IP_SCTP
 * 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


 * Option: SCTP_DBG_OBJCNT
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) SCTP: Debug object counts
 * depends on IP_SCTP
 * 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

"SCTP: Cookie HMAC Algorithm"


 * depends on IP_SCTP
 * default SCTP_HMAC_MD5
 * 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.
 * Note: This default was presumably set before MD5 was proved to be broken. See RH bug 485933.


 * Option: SCTP_HMAC_NONE
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) None
 * Choosing this disables the use of an HMAC during association establishment.  It is advised to use either HMAC-MD5 or HMAC-SHA1.


 * Option: SCTP_HMAC_SHA1
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) HMAC-SHA1
 * Enable the use of HMAC-SHA1 during association establishment. It  is advised to use either HMAC-MD5 or HMAC-SHA1.


 * Option: SCTP_HMAC_MD5
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) HMAC-MD5
 * Enable the use of HMAC-MD5 during association establishment. It is  advised to use either HMAC-MD5 or HMAC-SHA1.
