if an arriving packet belongs to us, also check that the packet arrived
through the correct interface. Skip this check if the packet was locally
generated.
fscale is a (64-bit) long. So just use a struct loadavg.
This fixes the recent failure of top on alphas:
top: sysctl(vm.loadavg...) failed: Cannot allocate memory
- use size_t for sizeof() so as to fix a few int/long warnings on alpha

Add the 'virtual nulmodem driver'
Particularly useful for debuging kernels using vmware.
If your name is Bruce evans and you are a WIZ at tty interfaces,
then you should probably rip this to shreds and offer lots of suggestions and
patches. I've been using this since 4.0-CURRENT and it's never caused
problems but I'm sure I got something wrong. This is similar to the pty/cty
device driver except that both sides are ttys. Even minor numbers
are side A and odd minor numbers are side B.
Work needs to be done regarding what happens to the other side when you
close a node.
to use with vmware, configure vmware to redirect COM2 out to side A of one
of these and boot a kernel with teh gdb remote port set to sio1.
AFTER dropping into the gdb kernel debugger in your test kernel,
fire up gdb with it's remote port pointing at the appropriate side B.
To catch all console output, you can boot the vmware kernel with a serial
console, (COM1) similarly redirected to a nulmodem, and use 'tip' to observe it.
This is practically unaltered since pre 4.0 days except for
changes made along the way needed to make it compile, so any suggestions
or offers of total rewrites will be listenned to :-)
Even better formula from random() could not be intetgrated because rand_r()
supposed to store its state in the single variable (but table needed for
random() algorithm integration).
and Pentium II, III and IV processors (p2, p3, p4), as well as 'mmx' and
'3dnow' MACHINE_CPU tags as appropriate. In the near future this will
be used to control various ports which have MMX/3dNow optimizations,
instead of the ad-hoc methods currently used.

When we recieve a fragmented TCP packet (other than the first) we can't
extract header information (we don't have state to reference). In a rather
unelegant fashion we just move on and assume a non-match.
Recent additions to the TCP header-specific section of the code neglected
to add the logic to the fragment code so in those cases the match was
assumed to be positive and those parts of the rule (which should have
resulted in a non-match/continue) were instead skipped (which means
the processing of the rule continued even though it had already not
matched).
Fault can be spread out over Rich Steenbergen (tcpoptions) and myself
(tcp{seq,ack,win}).
rwatson sent me a patch that got me thinking about this whole situation
(but what I'm committing / this description is mine so don't blame him).
pkg_delete(1) as well;
- add a new `-a' option for pkg_delete(1) to delete all installed packages;
- add a new `-i' option for pkg_delete(1) to request simple rm(1)-like
interactive confirmation before attempting to delete each package.

should really be using COMPAT_LINUX instead of the linux module on
dynamic systems like -current.

in VMware reports 0x00000000 in the PCI subsystem ID register, but
0x10001000 when you read the mirror registers in I/O space. This causes
pcn_probe() to think it's found a card in 32-bit mode, and performing
a 32-bit I/O access makes on a 16-bit port makes VMware go boom. Special
case the 0x10001000 value until somebody at VMware grows a clue.

For TCP, verify that the sequence number in the ICMP packet falls within
the tcp receive window before performing any actions indicated by the
icmp packet.
