"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" 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 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. config SCTP_HMAC_MD5 bool "HMAC-MD5" help Enable the use of HMAC-MD5 during association establishment. It is advised to use either HMAC-MD5 or HMAC-SHA1. endchoice endmenu
