Avoid duplicating ttselect() so that we don't have to change cyselect()
when ttselect() is improved. This requires using an array of tty structs
and not using ttymalloc().
Fix an off by 1 error. Some caclulations seem to be off by a factor
of NCY. NCY defaults to 16, which gives 256 tty structs occupying
0xd000 bytes. The minor number encoding only allows 16 ttys.
Fix couple of nasty bugs..
- Overflow now calculated right
- Close works ok,does not looses tty
- Better overflow handling now the snooping stops
on overflow,but programm notified and can reconnect if
it want to..Default maximal buffer set to 664 K and this
is probably too much..:)))

Don't bother calling pmap_create() when creating the temporary map.
The whole COW section of vm_mmap() should be rewritten; the current
implementation is highly convoluted.

>From a week or two ago I got kernel panics as soon as I tried to access my
tape drive. I traced it to sys/scsi/scsi_base.c where some code were added
to print the return values of the sense command. My tape drive returned a
extended flags value of 0x20, so the key that is the lower 4 bits, is 0.
The code uses "key-1" to index into a table and then the kernel go to never-
never land.
Here is a fix for this. Will somebody please apply it?
And fix some more compiler warnings. Then give up. /sys/net* is FULL of
bogus code! And besides, Poul's doing this already.. It's just that
fixing compiler warnings is sort of like eating potato chips.. :-)
This is a MS-DOS program, but is does something useful for us:
It boots FreeBSD from a running MS-DOS system.
It's compiled using some MS-DOS tools, but there is a binary
hidden in the uuencoded file. (Go ahead, flame me if you can come up
with a solution for the problem. Just saying "this is bad" doesn't count!)
Rod, you were right: one would have to deal with weird interfaces to the
memory managers, and it seems that Christian found them all, and made them
work.
Thanks Christian!

------------------
Hi Everybody!
This is version 1.5 of "fbsdboot", a program that allows you to boot a kernel
from a MS-DOS partition or a FreeBSD partition. This program runs using DOS.
It works with various memory managers (like EMM386, 386MAX) under certain
circumstances.
First, a FreeBSD kernel is always loaded to memory starting at 0x100000. To
assure that loading the kernel *does not* overwrite memory used by memory
managers, high memory for the kernel is allocated and after loading the kernel
it's moved to 0x100000.
Second, there are many ways to switch to protected mode which is necessary to
start the kernel. Each BIOS gives you the possibility to use INT15H (AH=89H)
to do that. But some memory-managers like 386max does not allow you to use
this method.
An other way to do the switch is to use DPMI services, but they do not
guarantee, that the protected mode application is executed with privilege
level 0. Therefore this method is *not* used.
VCPI services offer another way to switch to protected mode, and VCPI servers
are built into "emm386.exe", "386max" and "qemm". That's why, this method is
implemented in fbsdboot.exe.
Fbsdboot.exe tries to switch to protected mode using VCPI services. If they're
not available INT15H is used to do the switch. If that fails, it's not possible
for this version of fbsdboot.exe to boot a kernel :-(.
You can get commandline options of fbsdboot if you start it with "-?" as option!
I don't know, if fbsdboot works with QEMM, as I don't have the possibility to
test it.
Enjoy and have fun!
Christian.

Make conditionals on BIOSWAIT consistent with usage in io.c.
If you had 'BOOTWAIT=0' in your /etc/make.conf then biosboot wouldn't
compile. It was '#if' in io.c and '#ifdef' in probe_keyboard.c so I
changed the latter to '#if'.
Even if BOOTWAIT is undefined then '#if BOOTWAIT' becomes
'#if 0' so it should compile either way with this change.

Attempt to make the host route cache a bit smarter under conditions of
high load:
1) If there ever get to be more than net.inet.ip.rtmaxcache entries
in the cache, in_rtqtimo() will reduce net.inet.ip.rtexpire by
1/3 and do another round, unles net.inet.ip.rtexpire is less than
net.inet.ip.rtminexpire, and never more than once in ten minutes
(rtq_timeout).
2) If net.inet.ip.rtexpire is set to zero, don't bother to cache
anything.

Here it came-the all-brand-new snoop device..
Users-beware..
It is tested and working for me but probably have some bugs i
didn't noticed so test it and reply...
It can:
look at what's sent to the user from tty device
snoop on pty's,vty's and serial tty's
It (still) can't:
write to tty
see what user types in local echo mode
It is probably bad styled and
very dependant on tty_pty.c,sio.c and syscons.c
I would be really happy if another ppl would make their
changes because i am not sure this is the best snoop
we can have..but it is good..:)))))

This is only one part - the rest to follow in a couple of hours.
This part is a benign import, since it doesn't affect anything else.
The destructor always assumed that it would be called on objects created from
ONE constructor routine. This was bogus - there is also a system provided
constructor which does not allocate a pattern buffer. Make less assumptions.
Fix for rather stupid bug by which you couldn't set
ports for the destination IP addr/port.
Nobody reported this btw , while a lot of other things reported-
probably ppl does not use destination ports at all????
