- name change of prefered -> preferred
- CMT fast recover code added.
- Comment fixes in CMT.
- We were not giving a reason of cant_start_asoc per socket api
if we failed to get init/or/cookie to bring up an assoc. Change
so we don't just give a generic "comm lost" but look at actual
states of dying assoc.
- change "crc32" arguments to "crc32c" to silence strict/noisy
compiler warnings when crc32() is also declared
- A few minor tweaks to get the portable stuff truely portable
for sctp6_usrreq.c :-D
- one-2-one style vrf match problem.
- window recovery would leave chks marked for retran
during window probes on the sent queue. This would then
cause an out-of-order problem and assure that the flight
size "problem" would occur.
- Solves a flight size logging issue that caused rwnd
overruns, flight size off as well as false retransmissions.g
- Macroize the up and down of flight size.
- Fix a ECNE bug in its counting.
- The strict_sacks options was causing aborts when window probing
was active, fix to make strict sacks a bit smarter about what
the next unsent TSN is.
- Fixes a one-2-one wakeup bug found by Martin Kulas.
- If-defed out form, Andre's copy routines pending his
commit of at least m_last().. need to adjust for 6.2 as
well.. since m_last won't exist.

- ZONE get now also take a type cast so it does the
cast like mtod does.
- New macro SCTP_LIST_EMPTY, which in bsd is just
LIST_EMPTY
- Removal of const in some of the static hmac functions
(not needed)
- Store length changes to allow for new fields in auth
- Auth code updated to current draft (this should be the
RFC version we think).
- use uint8_t instead of u_char in LOOPBACK address comparison
- Some u_int32_t converted to uint32_t (in crc code)
- A bug was found in the mib counts for ordered/unordered
count, this was fixed (was referencing a freed mbuf).
- SCTP_ASOCLOG_OF_TSNS added (code will probably disappear
after my testing completes. It allows us to keep a
small log on each assoc of the last 40 TSN's in/out and
stream assignment. It is NOT in options and so is only
good for private builds.
- Some CMT changes in prep for Jana fixing his problem
with reneging when CMT is enabled (Concurrent Multipath
Transfer = CMT).
- Some missing mib stats added.
- Correction to number of open assoc's count in mib
- Correction to os_bsd.h to get right sha2 macros
- Add of special AUTH_04 flags so you can compile the code
with the old format (in case the peer does not yet support
the latest auth code).
- Nonce sum was incorrectly being set in when ecn_nonce was
NOT on.
- LOR in listen with implicit bind found and fixed.
- Moved away from using mbuf's for socket options to using
just data pointers. The mbufs were used to harmonize
NetBSD code since both Net and Open used this method. We
have decided to move away from that and more conform to
FreeBSD style (which makes more sense).
- Very very nasty bug found in some of my "debug" code. The
cookie_how collision case tracking had an endless loop in
it if you got a second retransmission of a cookie collision
case. This would lock up a CPU .. ugly..
- auth function goes to using size_t instead of int which
conforms to socketapi better
- Found the nasty bug that happens after 9 days of testing.. you
get the data chunk, deliver it and due to the reference to a ch->
that every now and then has been deleted (depending on the postion
in the mbuf) you have an invalid ch->ch.flags.. and thus you don't
advance the stream sequence number.. so you block the stream
permanently. The fix is to make local variables of these guys
and set them up before you have any chance of trimming the
mbuf.
- style fix in sctp_util.h, not sure how this got bad maybe in
the last patch? (aka it may not be in the real source).
- Found interesting bug when using the extended snd/rcv info where
we would get an error on receiving with this. Thats because
it was NOT padded to the same size as the snd_rcv info. We
increase (add the pad) so the two structs are the same size
in sctp_uio.h
- In sctp_usrreq.c one of the most common things we did for
socket options was to cast the pointer and validate the size.
This as been macro-ized to help make the code more readable.
- in sctputil.c two things, the socketapi class found a missing
flag type (the next msg is a notification) and a missing
scope recovery was also fixed.

- Added a short time wait (not used yet) constant
- Corrected the type of the crc32c table (it was
unsigned long and really is a uint32_t
- Got rid of the user of MHeaders until they
are truely needed by lower layers.
- Fixed an initialization problem in the readq structure
(ordering was off).
- Found yet another collision bug when the random number
generator returns two numbers on one side (during a collision)
that are the same. Also added some tracking of cookies
that will go away when we know that we have the last collision
bug gone.
- Fixed an init bug for book_size_scale, that was causing
Early FR code to run when it should not.
- Fixed a flight size tracking bug that was associated with
Early FR but due to above bug also effected all FR's
- Fixed it so Max Burst also will apply to Fast Retransmit.
- Fixed a bug in the temporary logging code that allowed a
static log array overflow
- hashinit_flags is now used.
- Two last mcopym's were converted to the macro sctp_m_copym that
has always been used by all other places
- macro sctp_m_copym was converted to upper case.
- We now validate sinfo_flags on input (we did not before).
- Fixed a bug that prevented a user from sending data and immediately
shuting down with one send operation.
- Moved to use hashdestroy instead of free() in our macros.
- Fixed an init problem in our timed_wait vtag where we
did not fully initialize our time-wait blocks.
- Timer stops were re-positioned.
- A pcb cleanup method was added, however this probably will
not be used in BSD.. unless we make module loadable protocols
- I think this fixes the mysterious timer bug.. it was a
ordering of locks problem in the way we did timers. It
now conforms to the timeout(9) manual (except for the
_drain part, we had to do this a different way due
to locks).
- Fixed error return code so we get either CONNREUSED or CONNRESET
depending on where one is in progression
- Purged an unused clone macro.
- Fixed a read erro code issue where we were NOT getting the proper
error when the connection was reset.

This also moves two 16 bit int's to become 32 bit
values so we do not have to use atomic_add_16.
Most of the changes are %p, casts and other various
nasty's that were in the orignal code base. With this
commit my machine will now do a build universe.. however
I as yet have not tested on a 64bit machine .. it may not work :-(
work is not just mine, but it is also the works of Peter Lei
and Michael Tuexen. They both are my two key other developers
working on the project.. and they need ata-boy's too:

I did do a make sysent which updated the
syscall's and sysproto.. I hope that is correct... without
it you don't build since we have new syscalls for SCTP :-0
So go out and look at the NOTES, add
option SCTP (make sure inet and inet6 are present too)
and play with SCTP.
I will see about comitting some test tools I have after I
figure out where I should place them. I also have a
lib (libsctp.a) that adds some of the missing socketapi
functions that I need to put into lib's.. I will talk
to George about this :-)
There may still be some 64 bit issues in here, none of
us have a 64 bit processor to test with yet.. Michael
may have a MAC but thats another beast too..
If you have a mac and want to use SCTP contact Michael
he maintains a web site with a loadable module with
this code :-)
