[SCTP]: Stop claiming that this is a "reference implementation"

2008-02-05T15:59:07+00:00

I was notified by Randy Stewart that lksctp claims to be
"the reference implementation".  First of all, "the
refrence implementation" was the original implementation
of SCTP in usersapce written ty Randy and a few others.
Second, after looking at the definiton of 'reference implementation',
we don't really meet the requirements.

[NET]: Simple ctl_table to ctl_path conversions.

2008-01-28T23:01:07+00:00

This patch includes many places, that only required
replacing the ctl_table-s with appropriate ctl_paths
and call register_sysctl_paths().

Nothing special was done with them.

SCTP: Allow ADD_IP to work with AUTH for backward compatibility.

2007-11-07T16:39:27+00:00

This patch adds a tunable that will allow ADD_IP to work without
AUTH for backward compatibility.  The default value is off since
the default value for ADD_IP is off as well.  People who need
to use ADD-IP with older implementations take risks of connection
hijacking and should consider upgrading or turning this tunable on.

[SCTP]: Implement SCTP-AUTH initializations.

2007-10-10T23:51:30+00:00

The patch initializes AUTH related members of the generic SCTP
structures and provides a way to enable/disable auth extension.

[SCTP]: Move sysctl_sctp_[rw]mem definitions to protocol.c

2007-10-10T23:51:23+00:00

The sctp_[rw]mem definitions should really be in protocol.c
since that is where they are initialized.  This also allows
one to build a kernel without sysctl support.

[SCTP]: Rewrite of sctp buffer management code

2007-10-10T23:48:09+00:00

This patch introduces autotuning to the sctp buffer management code
similar to the TCP.  The buffer space can be grown if the advertised
receive window still has room.  This might happen if small message
sizes are used, which is common in telecom environmens.
New tunables are introduced that provide limits to buffer growth
and memory pressure is entered if to much buffer spaces is used.

[PATCH] sysctl: remove insert_at_head from register_sysctl

2007-02-14T16:09:59+00:00

The semantic effect of insert_at_head is that it would allow new registered
sysctl entries to override existing sysctl entries of the same name.  Which is
pain for caching and the proc interface never implemented.

I have done an audit and discovered that none of the current users of
register_sysctl care as (excpet for directories) they do not register
duplicate sysctl entries.

So this patch simply removes the support for overriding existing entries in
the sys_sysctl interface since no one uses it or cares and it makes future
enhancments harder.

[SCTP]: Remove multiple levels of msecs to jiffies conversions.

2006-09-22T21:55:39+00:00

The SCTP sysctl entries are displayed in milliseconds, but stored
internally in jiffies. This results in multiple levels of msecs to
jiffies conversion and as a result produces a truncation error. This
patch makes things consistent in that we store and display defaults
in milliseconds and only convert once for use by association.
This patch also adds some sane min/max values so that we don't go off
the deep end.

[SCTP]: Fix bad sysctl formatting of SCTP timeout values on 64-bit m/cs.

2006-01-17T19:55:17+00:00

Change all the structure members that hold jiffies to be of type
unsigned long.  This also corrects bad sysctl formating on 64 bit
architectures.

[SCTP]: Include ulpevents in socket receive buffer accounting.

2005-11-12T00:08:24+00:00

Also introduces a sysctl option to configure the receive buffer
accounting policy to be either at socket or association level.
Default is all the associations on the same socket share the
receive buffer.
