This directory contains your kernel patch for
FreeBSD 6.0, 6.1 and if your brave 7.0.

You should make a directory someplace and 
unpack this tarball into it.

so you do:
vvvvvvv  STEP 1   vvvvvvvvvvvvvvv
cd ~
mkdir sctpCode
cd sctpCode
tar -zxf ~/sctp_tarball.tgz
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Now with that done go in to
KERN

vvvvvvv  STEP 2   vvvvvvvvvvvvvvv
cd KERN
or
cd ~/sctpCode/KERN
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Once there you should run the script
setup_freebsd_src.sh. You will be
asked for you source directory, which
you own and some other questions. Assuming
my source directory is
/usr/src/sys 
and my home directory where the
source is, is
/usr/rrs/sctpCode
and I am on 7.0 

Here is how I would run it note lines
with <--cr--> are what I input.

vvvvvvv  STEP 3   vvvvvvvvvvvvvvv
bash-stewlap: ./setup_freebsd_src.sh<--cr--> 
Where is your cvs path (e.g. /usr/rrs/sctpCVS)?
/usr/rrs/sctpCode<--cr--> 
Where is your kernel source code that you are using (e.g. /usr/src/sys)?
/usr/src/sys<--cr--> 
Will you be using 7.0 Current or FreeBSD 6.1 or 6.0 (7 or 61 or 60)?
7<--cr--> 
I will use 7.0 then, if unsure hit ctl-c else return

Preparing kernel SCTP sources now
Linking in SCTP sources
mv -f init_sysent.c init_sysent.c.bak
mv -f syscalls.c syscalls.c.bak
mv -f ../sys/syscall.h ../sys/syscall.h.bak
mv -f ../sys/syscall.mk ../sys/syscall.mk.bak
mv -f ../sys/sysproto.h ../sys/sysproto.h.bak
sh makesyscalls.sh syscalls.master
You may now go to your kernel source tree /usr/src/sys
Configure a new kernel with:
options SCTP
And build as normal
This script as already did a 
make sysent
In /usr/src/sys/kern so the syscalls are present
in the kernel. However you probably need to
copy these to /usr/include/sys and also
do a  make buildworld and make installworld
which will get the sctp_xxx calls into libc
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

vvvvvvv  STEP 4   vvvvvvvvvvvvvvv
Now once your script is run you are ready to
go build a kernel. You need to put in it

option SCTP

to turn on SCTP.. and then do a normal
config and make with your kernel. I won't
tell you how to do this, if you don't know
how go see the freebsd.org web site handbook.

You also will probably need to go cp
from your source tree:
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^


vvvvvvv  STEP 5a  vvvvvvvvvvvvvvv
cd /usr/src/sys/sys <cr>
cp mbuf.h /usr/include/sys
cp socket.h /usr/include/sys
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

You will also want to copy out
syscall.h
syscall.mk
sysproto.h

vvvvvvv  STEP 5b  vvvvvvvvvvvvvvv
cp syscall.h /usr/include/sys/
cp syscall.mk /usr/include/sys/
cp sysproto.h /usr/include/sys/
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Next to get the libsctp.a/.so go in to

vvvvvvv  STEP 6   vvvvvvvvvvvvvvv
cd sctpCode/KERN/usr.lib
make
cp libsctp* /lib
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

And then you probably will want to do

vvvvvvv  STEP 7   vvvvvvvvvvvvvvv
cd ~/sctpCode/KERN/export_freebsd/netinet
cp *.h /usr/include/netinet
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^


At this point you can reboot and you
should have a working SCTP kernel.
