Ok, here it is, we finally add SCTP to current. Note that this

Browse Source 
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 :-)

# libalias library, performing NAT
options LIBALIAS
#
# SCTP is a NEW transport protocol defined by
# RFC2960 updated by RFC3309 and RFC3758.. and
# soon to have a new base RFC and many many more
# extensions. This release supports all the extensions
# including many drafts (most about to become RFC's).
# It is the premeier SCTP implementation in the NET
# and is quite well tested.
#
# Note YOU MUST have both INET and INET6 defined.
# you don't have to enable V6, but SCTP is
# dual stacked and so far we have not teased apart
# the V6 and V4.. since an association can span
# both a V6 and V4 address at the SAME time :-)
#
options SCTP
# There are bunches of options:
# this one turns on all sorts of
# nastly printing that you can
# do. Its all controled by a
# bit mask (settable by socket opt and
# by sysctl). Including will not cause
# logging until you set the bits.. but it
# can be quite verbose.. so without this
# option we don't do any of the tests for
# bits and prints.. which makes the code run
# faster.. if you are not debugging don't use.
options SCTP_DEBUG
#
# High speed enables sally floyds HS TCP optioin
# for congestion control increase, use only in
# very HS networks and with caution since I doubt
# it will compete fairly with peers. For the big-bad
# internet its best NOT to enable.
#
options SCTP_HIGH_SPEED
#
# This option turns off the CRC32c checksum. Basically
# You will not be able to talk to anyone else that
# has not done this. Its more for expermentation to
# see how much CPU the CRC32c really takes. Most new
# cards for TCP support checksum offload.. so this
# option gives you a "view" into what SCTP would be
# like with such an offload (which only exists in
# high in iSCSI boards so far). With the new
# splitting 8's algorithm its not as bad as it used
# to be.. but it does speed things up try only
# for in a captured lab environment :-)
options SCTP_WITH_NO_CSUM
#
# Logging, this is another debug tool thats way
# cool.. but does take resources so its off
# by default. To do any logging you must first
# enable SCTP_STAT_LOGGING. This gets the utilities
# into the code base that actually do the logging and
# alocates a hugh fixed circular buffer that logging
# uses (about 80,000 entires that are probably 8 long
# words or so long.. so it does take a LOT of memory).
# Its cool for real-time debugging though.
#
options SCTP_STAT_LOGGING
#
# All that options after that turn on specific types of
# logging. You can monitor CWND growth, flight size
# and all sorts of things. Go look at the code and
# see. I have used this to produce interesting
# charts and graphs as well :->
#
# I have not yet commited the tools to get and print
# the logs, I will do that eventually .. before then
# if you want them send me an email rrs@freebsd.org

* Blocking I/O is enabled on any TCP type socket by default. For the UDP
* model if this is turned on then the socket buffer is shared for send
* resources amongst all associations. The default for the UDP model is that
* is SS_NBIO is set. Which means all associations have a seperate send
* limit BUT they will NOT ever BLOCK instead you will get an error back
* EAGAIN if you try to send to much. If you want the blocking symantics you
* set this option at the cost of sharing one socket send buffer size amongst
* all associations. Peeled off sockets turn this option off and block. But
* since both TCP and peeled off sockets have only one assoc per socket this
* is fine. It probably does NOT make sense to set this on SS_NBIO on a TCP
* model OR peeled off UDP model, but we do allow you to do so. You just use
* the normal syscall to toggle SS_NBIO the way you want.
*
* Blocking I/O is controled by the SS_NBIO flag on the socket state so_state

/**
*
* Routine Description:
*
* Computes the CRC32c checksum for the specified buffer using the slicing by 8
* algorithm over 64 bit quantities.
*
* Arguments:
*
* p_running_crc - pointer to the initial or final remainder value
* used in CRC computations. It should be set to
* non-NULL if the mode argument is equal to CONT or END
* p_buf - the packet buffer where crc computations are being performed
* length - the length of p_buf in bytes
* init_bytes - the number of initial bytes that need to be procesed before
* aligning p_buf to multiples of 4 bytes
* mode - can be any of the following: BEGIN, CONT, END, BODY, ALIGN
*
* Return value:
*
* The computed CRC32c value

/*
* General locking concepts: The goal of our locking is to of course provide
* consistency and yet minimize overhead. We will attempt to use
* non-recursive locks which are supposed to be quite inexpensive. Now in
* order to do this the goal is that most functions are not aware of locking.
* Once we have a TCB we lock it and unlock when we are through. This means
* that the TCB lock is kind-of a "global" lock when working on an
* association. Caution must be used when asserting a TCB_LOCK since if we
* recurse we deadlock.
*
* Most other locks (INP and INFO) attempt to localize the locking i.e. we try
* to contain the lock and unlock within the function that needs to lock it.
* This sometimes mean we do extra locks and unlocks and lose a bit of
* efficency, but if the performance statements about non-recursive locks are
* true this should not be a problem. One issue that arises with this only
* lock when needed is that if an implicit association setup is done we have
* a problem. If at the time I lookup an association I have NULL in the tcb
* return, by the time I call to create the association some other processor
* could have created it. This is what the CREATE lock on the endpoint.
* Places where we will be implicitly creating the association OR just
* creating an association (the connect call) will assert the CREATE_INP
* lock. This will assure us that during all the lookup of INP and INFO if
* another creator is also locking/looking up we can gate the two to
* synchronize. So the CREATE_INP lock is also another one we must use
* extreme caution in locking to make sure we don't hit a re-entrancy issue.
*
* For non FreeBSD 5.x we provide a bunch of EMPTY lock macros so we can
* blatantly put locks everywhere and they reduce to nothing on
* NetBSD/OpenBSD and FreeBSD 4.x
*
*/
/*
* When working with the global SCTP lists we lock and unlock the INP_INFO
* lock. So when we go to lookup an association we will want to do a
* SCTP_INP_INFO_RLOCK() and then when we want to add a new association to
* the sctppcbinfo list's we will do a SCTP_INP_INFO_WLOCK().
