| 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. |

| 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_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' |

| 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. |
