Hello!
Let me first say that beta4 and beta5 work great on 2 machines so I
decided to play with beta6 on latest FreeBSD 3.1-stable (sources fetched
today). I started with 'make freebsd30' with IPFLKM commented, because in
previous betas only kernel mode worked. First error:
cc -g -I../.. -DIPFILTER_LOG -Di386 -D__i386__ -DINET -DKERNEL -D_KERNEL
-I/us

Fixed by touch opt_posix.h. Next:

../../ip_fil.c: In function `send_reset':
../../ip_fil.c:859: too many arguments to function `ip_output'
*** Error code 1
Stop.
ip_output doesn't accept so many argument according to ip_output.c in
/usr/src/sysnetinet:
int
ip_output(m0, opt, ro, flags, imo)
struct mbuf *m0;
struct mbuf *opt;
struct route *ro;
int flags;
struct ip_moptions *imo;
The error is here:
# if defined(__FreeBSD_version) && (__FreeBSD_version >= 220000)
bzero((char *)&ro, sizeof(ro));
err = ip_output(m, (struct mbuf *)0, &ro, 0, 0, NULL);
<================ 6 params?
if (ro.ro_rt)
RTFREE(ro.ro_rt);
# else
/*
* extra 0 in case of multicast
*/
err = ip_output(m, (struct mbuf *)0, 0, 0, 0);
# endif
We can get rid of one zere and it goes further till ip_auth where we have
to edit again and get rid of one parameter (one NULL) to ip_output.
And 'make freebsd30' compiles! 'make install-bsd' goes correctly. Then the
picky part: FreeBSD-2.2/kinstall:
It fails here:
--------------------------

Most of the stuff is the except ip_optcopy loses 'static' in 'static int'
as return value. So now we can re-config the kernel and build it:
loading kernel
mlf_ipl.o: In function `iplaction':
mlf_ipl.o(.text+0x19): undefined reference to `lkmexists'
*** Error code 1
We get rid of iplaction in mlf_ipl.c and it compiles. We reboot and feel
proud to make it work. Great, huh? Then we go home and find out that our
ssh sessions stop responding if we're inactive for more than a minute. Not
so great, right? Then we build a kernel without ipfilter and sessions stay
like they used to. So it is not ssh.
Could be something in netinet in FreeBSD 3.1-stable that was changed since
30th March - I have a machine with FreeBSD 3.1-STABLE build with ipfilter
3.2.11beta5 and FreeBSD sources from that day which works perfect. I'm not
sure.
