# # SCTP configuration # menuconfig IP_SCTP tristate "The SCTP Protocol" depends on INET depends on IPV6 || IPV6=n select CRYPTO select CRYPTO_HMAC select CRYPTO_SHA1 select LIBCRC32C ---help--- Stream Control Transmission Protocol From RFC 2960 . "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. Debug messages are handeled by the kernel's dynamic debugging framework. If in doubt, say N. if IP_SCTP config NET_SCTPPROBE tristate "SCTP: Association probing" depends on PROC_FS && KPROBES ---help--- This module allows for capturing the changes to SCTP association state in response to incoming packets. It is used for debugging SCTP congestion control algorithms. If you don't understand what was just said, you don't need it: say N. To compile this code as a module, choose M here: the module will be called sctp_probe. 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.
