Commit 0d0863b020 ("sctp: Change defaults on cookie hmac selection")
added a "choice" to the sctp Kconfig file. It introduced a bug which
led to an infinite loop when while running "make oldconfig".
The problem is that the wrong symbol was defined as the default value
for the choice. Using the correct value gets rid of the infinite loop.
Note: if CONFIG_SCTP_COOKIE_HMAC_SHA1=y was present in the input
config file, both that and CONFIG_SCTP_COOKIE_HMAC_MD5=y be present
in the generated config file.

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.

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.
