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.

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

the sample boards Winbond sent me, so who knows how many

All drivers include support for ifmedia, BPF and hardware multicast
filtering.
Also updated GENERIC, LINT, RELNOTES.TXT, userconfig and

I also have a driver for the ASIX AX88140A in the works.
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 This code was originally made for NetBSD/pc98 by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>.

going to want a major number from that list instead. Also use the
same preallocated local range (500-600) for blkdevs as well as cdevs,
just to be orthogonal. The latter was for Brian, who has a *lot*
of local device drivers and needs more than just a single reserved
number.
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.
Reminded by: NIST-PCTS
Don't call timeout() for DTR wakeup if the relevant timeout is already
active. This fixes "timeout table full" panics when sufficiently many
cyopen()s are interrupted while they are sleeping waiting for the
timeout to expire.
install all those images at all (nor to install them under /usr/mdec), given
the high degree of customization this Makefile needs in order to get images
that are actually useful for some NIC.

were half of their physical offsets for ISA and 1/4 of their physical
offsets for PCI, while all other Cyclades offsets were physical/1 for
ISA and physical/2 for PCI. Logically wrong macros were used to scale
CY16_RESET and CY_CLEAR_INTR to the correct physical offsets.
Fixed some style bugs (mostly long lines).
out interrupts for too long. If you still see the "calcru: negative
time..." message you can increase NTIMECOUNTER (see LINT).
Sideeffect is that a timecounter is required to not wrap around in
less than (1 + delta) seconds instead of the (1/hz + delta) required
until now.

interrupt handlers. Instead, load and use it atomically as necessary.
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
doing output. Waiting for (some) output to drain is not permitted for
the TCSANOW case of tcsetattr(). NIST-PCTS easily detects bugs like
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).
This finishes fixing all sio(16550)-related bugs found by NIST-PCTS.
keyboard/mouse/display switch products (console switches). Some

talks to the mouse while the mouse is actually routed to another
host.
flags 0x200 Do not try to identify the mouse model. All
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.
- Added another flag for pad devices.
flags 0x800 Assume the pad behaves like ALPS GlidePoint
when the user `taps' the surface of the pad;
it will be reported as the fourth button.

devstart_start_transaction() call is misplaced - it is after the
wdustart() call that queues the transaction on the controller queue.
Normally this doesn't matter because we're running at splbio() so
nothing will look at the controller queue. However, obsolescent
code for syncing labels sometimes slept after the transaction was
started, so the transaction sometimes completed before it was
[recorded as] started. This code was misplaced even for syncing
labels. Move it to the right place. It should go away, but
something may depend on its side effects.
truncated to 32 bits.
* Change the calling convention of the device mmap entry point to
pass a vm_offset_t instead of an int for the offset allowing
devices with a larger memory map than (1<<32) to be supported
on the alpha (/dev/mem is one such).
These changes are required to allow the X server to mmap the various
I/O regions used for device port and memory access on the alpha.
