- Sysctl's move to seperate file
- moved away from ifn/ifa access to sctp_ifa/sctp_ifn
built and managed by the add-ip code.
- cleaned up add-ip code to use the iterator
- made iterator be a thread, which enables auto-asconf now.
- rewrote and cleaned up source address selection (also
made it use new structures).
- Fixed a couple of memory leaks.
- DACK now settable as to how many packets to delay as
well as time.
- connectx() to latest socket API, new associd arg.
- Fixed issue with revoking and loosing potential to
send when we inflate the flight size. We now inflate
the cwnd too and deflate it later when the revoked
chunk is sent or acked.
- Got rid of some temp debug code
- src addr selection moved to a common file (sctp_output.c)
- Support for simple VRF's (we have support for multi-vfr
via compile switch that is scrubbed from BSD but we won't
need multi-vrf until we first get VRF :-D)
- Rest of mib work for address information now done
- Limit number of addresses in INIT/INIT-ACK to
a #def (30).

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.

- Macroizes the V6ONLY flag check.
- 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.

b) removal of all use of pkt-hdr's until only
the places we need them (before ip_output routines).
c) remove a bunch of code not needed due to <b> aka
worrying about pkthdr's :-)
d) There was one last reorder problem it looks where
if a restart occur's and we release and relock (at
the point where we setup our alias vtag) we would
end up possibly getting the wrong TSN in place. The
code that fixed the TSN's just needed to be shifted
around BEFORE the release of the lock.. also code that
set the state (since this also could contribute).

Ok, here it is, we finally add SCTP to current. Note that this
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:
****
peterlei@cisco.com
tuexen@fh-muenster.de

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 :-)

Build on Jeff Roberson's linker-set based dynamic per-CPU allocator
(DPCPU), as suggested by Peter Wemm, and implement a new per-virtual
network stack memory allocator. Modify vnet to use the allocator
instead of monolithic global container structures (vinet, ...). This
change solves many binary compatibility problems associated with
VIMAGE, and restores ELF symbols for virtualized global variables.

Each virtualized global variable exists as a "reference copy", and also
once per virtual network stack. Virtualized global variables are
tagged at compile-time, placing the in a special linker set, which is
loaded into a contiguous region of kernel memory. Virtualized global
variables in the base kernel are linked as normal, but those in modules
are copied and relocated to a reserved portion of the kernel's vnet
region with the help of a the kernel linker.

Virtualized global variables exist in per-vnet memory set up when the
network stack instance is created, and are initialized statically from
the reference copy. Run-time access occurs via an accessor macro, which
converts from the current vnet and requested symbol to a per-vnet
address. When "options VIMAGE" is not compiled into the kernel, normal
global ELF symbols will be used instead and indirection is avoided.

This change restores static initialization for network stack global
variables, restores support for non-global symbols and types, eliminates
the need for many subsystem constructors, eliminates large per-subsystem
structures that caused many binary compatibility issues both for
monitoring applications (netstat) and kernel modules, removes the
per-function INIT_VNET_*() macros throughout the stack, eliminates the
need for vnet_symmap ksym(2) munging, and eliminates duplicate
definitions of virtualized globals under VIMAGE_GLOBALS.

Bump __FreeBSD_version and update UPDATING.
