73579c400f Add a check to make sure that we don't fiddle with the NFS routing tables
as well (bleah!).  Also, increase the interval to the real-life value and
eliminate debugging printfs.  This will be standard once tested by others.

As before, this is currently conditionalized on options IN_RMX until
I'm sure it's working.

a7d72265c4 The values for setrlimit in the data size and stack size case are
used as an address value. Then all comparisons should be done unsigned
and not signed. Fix it with a typecast of u_quad_t.
Error can be demonstrated with the current bash in port, do a
ulimit -s unlimited and the machine hangs. bash delivers through
an internal error a large negative value for the stacksize, the
comparison saw this smaller than MAXSSIZ and then tried to expand
the stack to this size.

89384ace85 Fix bug I introduced that broke BPF support. Caused by a byte order problem
in an if () expression. Problem fixed by removing the test for ETHERTYPE_*
before passing packet to higher layers.

1ca6f46d56 Reverse the meaning of previous change.
Now floppy tape support is *disabled* unless you specifically
request otherwise.  Poul wanted it this way, and I guess I'm not going to argue
though it may seem counter-intuitive.  We can always change it back, later.

cb0d548bf4 Merge in latest Linux sequencer code release with my changes. This should
make the sequencer code fully compatible with the aic7870 (ie 294x adaptors).
I've also added to my local mods putting the sequencer into "FASTMODE" clock.
This gives upwards of 2M/sec write preformance improvement in some scenarios.
There haven't been any reports of this causing problems, and I have been
reaping the benifits of it for more than a week now.

This also includes a new version of the pre-generated file <ugh>

d439025208 Temporary kludge: treat \r same as \n in input, so working on a
comconsole will behave as expected.  The true problem should be fixed
instead, Bruce' comment for this:

>Anyway, i found the reason for my problems: somehow, ICRNL isn't in
>effect at `userconfig' time (but only for comconsole?), hence only

ICRNL doesn't apply to cngetc().  cnputc() unconditionally does the
equivalent of ONLCR; perhaps cngetc() should unconditionally do the
equivalent of ICRNL.  Ddb must be checking for CR.  Userconfig only
checks for NL.  Userconfig works with syscons because pccngetc()
does the conversion.  This is probably the wrong place to do it.

Allow chown() to return success if the gid isn't changed even if
the gid is not the caller's.  Such gids are normal for files created
in world-writable directories sucj as /tmp.  This "fixes" annoying
error messages for mv'ing files created in /tmp to another file
system.  mv still preserves the foreign gid of /tmp, but now does
it silently.

d1a795a280 Fix cblock starvation bugs by reserving enough cblocks for minimal
operation of each clist.  Limit the growth of each clist.  Clists
can only grow larger than the reserved minimum if there are free
cblocks in a shared pool.  The size of this pool is now fixed
(this could be improved).  The reserved and maximum sizes are more
carefully allocated for slip and ppp, depending on the mtu.  A maximum
MTU of 16384 is now enforced for ppp.

eadf9e27cd These changes fix a couple of lingering VM problems:
1.	The pageout daemon used to block under certain
	circumstances, and we needed to add new functionality
	that would cause the pageout daemon to block more often.
	Now, the pageout daemon mostly just gets rid of pages
	and kills processes when the system is out of swap.
	The swapping, rss limiting and object cache trimming
	have been folded into a new daemon called "vmdaemon".
	This new daemon does things that need to be done for
	the VM system, but can block.  For example, if the
	vmdaemon blocks for memory, the pageout daemon
	can take care of it.  If the pageout daemon had
	blocked for memory, it was difficult to handle
	the situation correctly (and in some cases, was
	impossible).

2.	The collapse problem has now been entirely fixed.
	It now appears to be impossible to accumulate unnecessary
	vm objects.  The object collapsing now occurs when ref counts
	drop to one (where it is more likely to be more simple anyway
	because less pages would be out on disk.)  The original
	fixes were incomplete in that pathological circumstances
	could still be contrived to cause uncontrolled growth
	of swap.  Also, the old code still, under steady state
	conditions, used more swap space than necessary.  When
	using the new code, users will generally notice a
	significant decrease in swap space usage, and theoretically,
	the system should be leaving fewer unused pages around
	competing for memory.

b83f4f55d8 Bunch of fixes from Matt Thomas:
1) make #includes correct
2) fix bugs in address check macros
3) fixed bugs in, and enabled, recopy if heavily fragmented code
4) moved call to bpf tap to be before enqueing packet (probably gratuitous)
5) fixed bug that caused "abnormal interrupt" at boot time/first use
6) added support for reading Zynx address ROM
7) fixed bug that caused broadcasts to not work shortly after booting (only
	manifested if not using multicast - e.g. not in FreeBSD 2.0)
8) fixed spelling errors in comments

9b1096e759 From: wpaul@ctr.columbia.edu (Bill Paul)
Subject: Mea culpa -- small fix for netboot fixes

In accordance with the unavoidable principle sof Murphy's Law, I discovered
that the fixes I recently contributed for the netboot code had some small
flaws in them. Two of them were just typos and had no effect on how the
program functioned. The other one was a missing line from the rootopts and
swapopts functions I created in bootmenu.c, which was supposed to initialize
the NFS sotype flag. It defaults to UDP, and you can change it to TCP with
the rootopts or swapopts commands, but then you can't change it back again.
I originally had a line at the top of each function to reinitialize this
flag, but somehow it got lost in the shuffle, probably because I don't
actually have a need for that flag yet.

e0985944c1 Improve the case for ST506 disks a bit: Pick up Bios-geometry.
That was the good news.  The bad news is that bad144 is a proper mess,
and I don't have time to fix it now, so you will probably not be able to
use it anyway.
Sorry guys, go out and buy a 100Mb IDE drive and a paddleboard :-(
If somebody wants to pick up on this:  bad144 needs to learn how to
stay inside our slice of the disk.  That's the trick.
