| 17 | |
| 18 | From RFC 2960 <http://www.ietf.org/rfc/rfc2960.txt>. |

| 20 | "SCTP is a reliable transport protocol operating on top of a |
| 21 | connectionless packet network such as IP. It offers the following |
| 22 | services to its users: |
| 23 | |
| 24 | -- acknowledged error-free non-duplicated transfer of user data, |
| 25 | -- data fragmentation to conform to discovered path MTU size, |
| 26 | -- sequenced delivery of user messages within multiple streams, |
| 27 | with an option for order-of-arrival delivery of individual user |
| 28 | messages, |
| 29 | -- optional bundling of multiple user messages into a single SCTP |
| 30 | packet, and |
| 31 | -- network-level fault tolerance through supporting of multi- |
| 32 | homing at either or both ends of an association." |
| 33 | |
| 34 | To compile this protocol support as a module, choose M here: the |
| 35 | module will be called sctp. |
| 36 | |
| 37 | If in doubt, say N. |

| 41 | depends on IP_SCTP |
| 42 | help |
| 43 | If you say Y, this will enable verbose debugging messages. |
| 44 | |
| 45 | If unsure, say N. However, if you are running into problems, use |
| 46 | this option to gather detailed trace information |

| 49 | bool "SCTP: Debug object counts" |
| 50 | depends on IP_SCTP |
| 51 | help |
| 52 | If you say Y, this will enable debugging support for counting the |
| 53 | type of objects that are currently allocated. This is useful for |
| 54 | identifying memory leaks. If the /proc filesystem is enabled this |
| 55 | debug information can be viewed by |
| 56 | 'cat /proc/net/sctp/sctp_dbg_objcnt' |
| 57 | |
| 58 | If unsure, say N |

| 64 | help |
| 65 | HMAC algorithm to be used during association initialization. It |
| 66 | is strongly recommended to use HMAC-SHA1 or HMAC-MD5. See |
| 67 | configuration for Cryptographic API and enable those algorithms |
| 68 | to make usable by SCTP. |

| 71 | bool "None" |
| 72 | help |
| 73 | Choosing this disables the use of an HMAC during association |
| 74 | establishment. It is advised to use either HMAC-MD5 or HMAC-SHA1. |
