sctp: Change defaults on cookie hmac selection

2012-12-16T01:14:38+00:00

Recently I posted commit 3c68198e75 which made selection of the cookie hmac
algorithm selectable.  This is all well and good, but Linus noted that it
changes the default config:
http://marc.info/?l=linux-netdev&m=135536629004808&w=2

I've modified the sctp Kconfig file to reflect the recommended way of making
this choice, using the thermal driver example specified, and brought the
defaults back into line with the way they were prior to my origional patch

Also, on Linus' suggestion, re-adding ability to select default 'none' hmac
algorithm, so we don't needlessly bloat the kernel by forcing a non-none
default.  This also led me to note that we won't honor the default none
condition properly because of how sctp_net_init is encoded.  Fix that up as
well.

Tested by myself (allbeit fairly quickly).  All configuration combinations seems
to work soundly.

sctp: Fix compiler warning when CONFIG_DEBUG_SECTION_MISMATCH=y

2012-12-07T17:57:13+00:00

WARNING: net/sctp/sctp.o(.text+0x72f1): Section mismatch in reference
from the function sctp_net_init() to the function
.init.text:sctp_proc_init()
The function sctp_net_init() references
the function __init sctp_proc_init().
This is often because sctp_net_init lacks a __init
annotation or the annotation of sctp_proc_init is wrong.

And put __net_init after 'int' for sctp_proc_init - as it is done
everywhere else in the sctp-stack.

sctp: Make hmac algorithm selection for cookie generation dynamic

2012-10-26T06:22:18+00:00

Currently sctp allows for the optional use of md5 of sha1 hmac algorithms to
generate cookie values when establishing new connections via two build time
config options.  Theres no real reason to make this a static selection.  We can
add a sysctl that allows for the dynamic selection of these algorithms at run
time, with the default value determined by the corresponding crypto library
availability.
This comes in handy when, for example running a system in FIPS mode, where use
of md5 is disallowed, but SHA1 is permitted.

Note: This new sysctl has no corresponding socket option to select the cookie
hmac algorithm.  I chose not to implement that intentionally, as RFC 6458
contains no option for this value, and I opted not to pollute the socket option
namespace.

Change notes:
v2)
	* Updated subject to have the proper sctp prefix as per Dave M.
	* Replaced deafult selection options with new options that allow
	  developers to explicitly select available hmac algs at build time
	  as per suggestion by Vlad Y.

2012-08-15T06:29:53+00:00

- Convert all of the files under /proc/net/sctp to be per
  network namespace.

- Don't print anything for /proc/net/sctp/snmp except in
  the initial network namespaces as the snmp counters still
  have to be converted to be per network namespace.
