982e80577d 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.

dfd7dd0c59 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.

72f8d0d43a - 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  This code was originally made for NetBSD/pc98 by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>.

b6d9e06815 * Fix a couple of places in the device pager where an address was
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.

90bdf0d597 Remove the USERCONFIG_BOOT option. Userconfig script data is searched
for in a loaded module of type "userconfig_script".  The RB_CONFIG
flag will always result in the user being left inside userconfig at
the end of the script's execution, regardless of 'quit' commands in
the script.  If the RB_CONFIG flag is not specified, the user will
never be left inside userconfig, even if the script does not have an
explicit exit command.

Add the INTRO_USERCONFIG option.  This option forces the userconfig 'intro'
screen (after a script has optionally been executed).  There is no longer
a need to queue an 'intro' command.

f89f94ea93 Quote port names that have a digit in them. IO_TIMER1 was lexed as
{ port_name = "IO_TIMER", port_number = 1 } and only worked because
it was reassembled to "IO_TIMER1".  Trailing digits always work, but
this is too magic to depend on.

Don't quote port names that don't have a digit in them.

464de37ce6 *gulp*. Jordan specifically OK'ed this..
This is the bulk of the support for doing kld modules.  Two linker_sets
were replaced by SYSINIT()'s.  VFS's and exec handlers are self registered.
kld is now a superset of lkm.  I have converted most of them, they will
follow as a seperate commit as samples.
This all still works as a static a.out kernel using LKM's.

3defb6d13f Fixed two potentially serious classes of bugs:
1) The vnode pager wasn't properly tracking the file size due to
   "size" being page rounded in some cases and not in others.
   This sometimes resulted in corrupted files. First noticed by
   Terry Lambert.
   Fixed by changing the "size" pager_alloc parameter to be a 64bit
   byte value (as opposed to a 32bit page index) and changing the
   pagers and their callers to deal with this properly.
2) Fixed a bogus type cast in round_page() and trunc_page() that
   caused some 64bit offsets and sizes to be scrambled. Removing
   the cast required adding casts at a few dozen callers.
   There may be problems with other bogus casts in close-by
   macros. A quick check seemed to indicate that those were okay,
   however.

code.

Fixed the pre-attach conflict message.  The flag for distinguishing
pre-attach conflict checks from pre-probe ones was never set.

482ceee22c Relocate the preload module info from machdep specifically rather than
trying to do it in locore.  We also walk through the module table
and relocate any MODINFO_ADDR pointers so that they become KVM relative
rather than physical addresses.  This means that hacks for adding
0xf0000000 in places like MFS go away.

04f5e2e068 Fix a parent tag reference count bug during tag teardown.
Enable optimization for nobounce_dmamap clients by setting the map
held by the client to NULL.  This allows the macros in bus.h to check
against a constant to avoid function calls.

Don't attempt to 'free()' contigmalloced pages in bus_dmamem_free().
We currently leak these pages, which is not ideal, but is better than
a panic.  The leak will be fixed when contigmalloc is merged into the
bus dma framework after 3.0R.
