a29a5bd4f5 [SCTP]: Implement SCTP-AUTH initializations.
The patch initializes AUTH related members of the generic SCTP
structures and provides a way to enable/disable auth extension.

007e3936bd [SCTP]: Move sysctl_sctp_[rw]mem definitions to protocol.c
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.

4d93df0abd [SCTP]: Rewrite of sctp buffer management code
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.

0b4d414714 [PATCH] sysctl: remove insert_at_head from register_sysctl
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.

3fd091e73b [SCTP]: Remove multiple levels of msecs to jiffies conversions.
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.

8116ffad41 [SCTP]: Fix bad sysctl formatting of SCTP timeout values on 64-bit m/cs.
Change all the structure members that hold jiffies to be of type
unsigned long.  This also corrects bad sysctl formating on 64 bit
architectures.

049b3ff5a8 [SCTP]: Include ulpevents in socket receive buffer accounting.
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.

1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
