e1501bb6eb Backed out the FIOASYNC fix in rev.1.108. fcntl(fd, F_SETFL, flags)
depends on the bug.  It does an FIOASYNC ioctl to sync the setting
of the O_ASYNC "file" flag with drivers even if the setting hasn't
changed.

f7c9e34bea If there is no .depends file, use the standard ad-hoc way of ensuring
that the generated files are generated before any of the object files.
Also minor cleanup of dependencies in conf/files that I bogusly added
before.

This should fix the requirement that make depend be done starting from
a clean config directory.  If you don't have a clean directory, make
depend is still required if you want the proper .o's to be recompiled.

2127f26023 Examine all occurrences of sprintf(), strcat(), and str[n]cpy()
for possible buffer overflow problems. Replaced most sprintf()'s
with snprintf(); for others cases, added terminating NUL bytes where
appropriate, replaced constants like "16" with sizeof(), etc.

These changes include several bug fixes, but most changes are for
maintainability's sake. Any instance where it wasn't "immediately
obvious" that a buffer overflow could not occur was made safer.

c13be48aee Put back some missing chip identification code that got lost somehow
during a trek through RCS. The Macronix 98713 and 98713A both have the
same PCI device ID but different revision numbers, and we need to be
able to tell one from the other. The 98715 and 98715A chips have the
same device ID as the 98725 chip but different revision numbers, however
we lump them into the same category except when identifying them during
the PCI probe output.

The main reason we need tell the chips apart is that the Macronix app
notes say you have to write a special magic number into one of the
registers in order to put the chip in normal operating mode. The 98713
requires one magic value, while all the others require a different one.

726ff6a158 An early Christmas present: add driver support for a whole bunch of
PCI fast ethernet adapters, plus man pages.

if_pn.c: Netgear FA310TX model D1, LinkSys LNE100TX, Matrox FastNIC 10/100,
         various other PNIC devices

if_mx.c: NDC Communications SOHOware SFA100 (Macronix 98713A), various
         other boards based on the Macronix 98713, 98713A, 98715, 98715A
         and 98725 chips

if_vr.c: D-Link DFE530-TX, other boards based on the VIA Rhine and
         Rhine II chips (note: the D-Link and certain other cards
         that actually use a Rhine II chip still return the PCI
         device ID of the Rhine I. I don't know why, and it doesn't
         really matter since the driver treats both chips the same
         anyway.)

if_wb.c: Trendware TE100-PCIE and various other cards based on the
         Winbond W89C840F chip (the Trendware card is identical to
         the sample boards Winbond sent me, so who knows how many
         clones there are running around)

All drivers include support for ifmedia, BPF and hardware multicast
filtering.

Also updated GENERIC, LINT, RELNOTES.TXT, userconfig and
sysinstall device list.

I also have a driver for the ASIX AX88140A in the works.

5b38fe900d Implement 'software completion' for floating point arithmetic. On the
alpha, operations involving non-finite numbers or denormalised numbers
or operations which should generate such numbers will cause an arithmetic
exception.  For programs which follow some strict code generation rules,
the kernel trap handler can then 'complete' the operation by emulating
the faulting instruction.

To use software completion, a program must be compiled with the arguments
'-mtrap-precision=i' and '-mfp-trap-mode=su' or '-mfp-trap-mode=sui'.
Programs compiled in this way can use non-finite and denormalised numbers
at the expense of slightly less efficient code generation of floating
point instructions.  Programs not compiled with these options will receive
a SIGFPE signal when non-finite or denormalised numbers are used or
generated.

Add ICMP_BANDLIM option and 'net.inet.icmp.icmplim' sysctl.  If option
    is specified in kernel config, icmplim defaults to 100 pps.  Setting it
    to 0 will disable the feature.  This feature limits ICMP error responses
    for packets sent to bad tcp or udp ports, which does a lot to help the
    machine handle network D.O.S. attacks.

    The kernel will report packet rates that exceed the limit at a rate of
    one kernel printf per second.  There is one issue in regards to the
    'tail end' of an attack... the kernel will not output the last report
    until some unrelated and valid icmp error packet is return at some
    point after the attack is over.  This is a minor reporting issue only.

not like the 6-byte read and write commands!  It returns illegal request,
with the field pointer pointing to byte 9 of a 6 byte CDB.

In any case, the work around is to put in a quirk mechanism that makes sure
that we don't send 6-byte reads or writes to this device.  It's rather sad
that this is necessary.  You'd think that they would be able to get
something that basic to work right in their firmware...

9ad861edee - For some old Cyrix CPUs, %cr2 is clobbered by interrupts. This
problem is worked around by using an interrupt gate for the page
   fault handler.  This code was originally made for NetBSD/pc98 by
   Naofumi Honda <honda@kururu.math.sci.hokudai.ac.jp> and has already
   been in PC98 tree.  Because of this bug, trap_fatal cannot show
   correct page fault address if %cr2 is obtained in this function.
   Therefore, trap_fatal uses the value from trap() function.
-  The trap handler always enables interruption when buggy application
   or kernel code has disabled interrupts and then trapped.  This code
   was prepared by Bruce Evans <bde@FreeBSD.org>.

makes the the get{nano|micro}*() functions call the real thing at
resulting in a measurable but minor overhead.

I decided to NOT have the "calcru" change the method automatically
because you should be aware of this problem if you have it.

The problems currently seen, related to usleep and a few other corners
are fixed for both methods.

is completely empty.  There is an interrupt for output completion.  It
is painful to use, but polling method used in the corresponding fix in
sio.c (rev.1.152) can't be used because there is no status bit for
transmitter-empty.  Now ttywait() works right.

08c6fbfa40 Change the delivery mechanism for incoming target commands. We now
use a 256 entry ring buffer of descriptersfor this purpose.  This allows
the use of a simple 8bit counter in the sequencer code for tracking start
location.

Entries in the ring buffer now contain a "cmd_valid" byte at their tail.
As an entry is serviced, this byte is cleared by the kernel and set by
the sequencer during its dma of a new entry.  Since this byte is the last
portion of the command touched during a dma, the kernel can use this
byte to ensure the command it processes is completely valid.

The new command format requires a fixed sized DMA from the controller
to deliver which allowed for additional simplification of the sequencer
code.  The hack that required 1 SCB slot to be stolen for incoming
command delivery notification is also gone.

9d2b090975 We can't call fsetown() from sonewconn() because sonewconn() is be called
from an interrupt context and fsetown() wants to peek at curproc, call
malloc(..., M_WAITOK), and fiddle with various unprotected data structures.
The fix is to move the code that duplicates the F_SETOWN/FIOSETOWN state
of the original socket to the new socket from sonewconn() to accept1(),
since accept1() runs in the correct context.  Deferring this until the
process calls accept() is harmless since the process can't do anything
useful with SIGIO on the new socket until it has the descriptor for that
socket.

One could make the case for not bothering to duplicate the
F_SETOWN/FIOSETOWN state and requiring the process to explicitly make the
fcntl() or ioctl() call on the new socket, but this would be incompatible
with the previous implementation and might break programs which rely on
the old semantics.

This reduces mode switching overhead for "polled" mode interrupt handling
from 5 i/o's to 3 (per service type, per port) so that polled mode is only
slightly more inefficient than "interrupt" mode.

UARTs when their divisor latch registers are selected while they are

this by testing at at speeds that no one would want to use (50 bps).

Deleted stale comments related to flushing i/o.  Flushing works properly
for 16550s according to NIST-PCTS (it can't work properly for 16450s).

7dd89537f1 Fixed some missing cases in the check for ioctls that involve modification.
Many (mostly machine-dependent ones) are still missing.  NIST-PCTS found
this bug for all the ioctls used to implement the POSIX tc* functions
(TIOCCBRK, TIOCDRAIN, TIOCSPGRP, TIOCSBRK, TIOCSTART and TIOCSTOP), and
I found FIOASYNC, TIOCCONS, TIOCEXCL, TIOCHPCL, TIOCNXCL, TIOCSCTTY and
TIOCSDRAINWAIT by inspection.  TIOCSPGRP was ifdefed out for some reason.

Handle tcsetattr()'s historical speed conversions correctly and more
centrally:
- don't store speeds of 0 in the final termios struct.  Drivers can now
  depend on tp->t_ispeed and tp->t_ospeed giving the actual speed.
  Applications can now depend on tcgetattr() being POSIX.1 conformant.
- convert from a proposed input speed of 0 to the proposed output speed
  (except if that is 0, convert to the current output speed).  Drivers
  can now depend on the proposed input speed being nonzero.
- don't reject negative speeds.  Negative speeds can't happen now that
  speed_t is unsigned, and rejecting invalid speeds is a bug - tcsetattr()
  is supposed to succeed if it can "perform any of the requested actions",
  so it shouldn't fail in practice.

			mice will be recognized as "generic PS/2".
	      0x400	Do not reset the mouse.  Some switches' response
			to the reset command is too slow and the psm
			will timeout.
	      0x1000	Relax error checking when probing the mouse
			port.

9abd5d84ac This fixes a bug in the bcache code whereby false cache hits occur
the first time block 0 is read. This fix initialises the block
numbers to -1 which isn't the most correct thing for a daddr_t but
it isn't likely to cause a problem in the boot blocks and it could
do with a more thought out fix later.

The bug is probably benign on the i386 but on the alpha it can
cause initial file opens to fail. This is the cause of the "can't
open /boot/boot.conf" errors.

It appears on the alpha because of a number of combining factors.
On the alpha the LABELSECTOR is 0 so block 0 needs to be read in
from the media. The first time this happens you get a false hit
because the bc_blkno field is zero initially. Also, the timestamp
check against this cache hit succeeds because on the alpha a hacked
getsecs() function can return 0 when it starts counting so that
the zero initial timestamp + BCACHE_TIMEOUT is greater than the
current time until getsecs() has counted passed BCACHE_TIMEOUT.

The overall effect is that the first open() that occurs gets a
false cache hit and returns garbage to the bd_strategy() function
which then fails the open() call. This false hit then stays in the
cache until BCACHE_TIMEOUT getsecs() ticks have passed; all open()
calls during this time fail.

This explains why you can generally access the media by the time
you get to interp() and start issuing commands but the earlier
attempts to run the boot scripts are failing.

It's possible that this is causing the problem switching to the
mfsroot floppy as well but I haven't confirmed that.
