When using cp to copy a file under the following circumstanes:

- original file in on an NFS filesystem
- destination file is on the same NFS filesystem
- the file is less than 8Mbytes in size
- the file is larger than 65536 bytes in size

the cp process can get frozen in device-wait and never wake up (cp uses
mmap() in this case).
A small change to allocbuf() fixes this.

f06a45ddd7 Removed hardcoded definition for RB_SERIAL that I left in my accident
(had it there for testing purposes). RB_SERIAL should be found in
<sys/reboot.h>.

Obtained from:
bios boot block changed to allow booting from both the attached graphics
display and from a serial port. (A specially compiled serial boot block
is no longer necessary.) The boot block should detect the presence or
absence of a keyboard: if there is no keyboard, COM1 is turned into the
console. This simulates the behavior of the Sun boot PROMs. Unplug your
keyboard, attach a terminal to COM1 and you should be ready to go. :)

2b237b4058 Submitted by: Bill Paul (wpaul@ctr.columbia.edu)
Obtained from:
sio.c and sioreg.c changed to allow autodetecting the RB_SERIAL flag
passed by the boot blocks so that the kernel can switch to 'serial
console' mode automagically. 'options COMCONSOLE' can still be specified
to force the kernel to always use the serial port as a console.
CONUNIT and CONADDR can also be specified in the kernel config file
if the user wants to shift the console to a different port.

c665f1dabd Submitted by: Bill Paul (wpaul@ctr.columbia.edu)
Obtained from:
Added a new flag (RB_SERIAL) which is passed by the boot block to tell
the kernel that it should use a serial port as a console. (The kernel
can still be forced to boot in serial console mode if 'options COMCONSOLE'
is used.)

2d2fb1bf6b The %eflags checking introduced in the previous commit was too zealous.
sigreturn() sometimes failed for ordinary returns from signal handlers.
Failures of ordinary returns "can't happen" and are badly handled.
"Temporary" fix: allow users to corrupt PSL_RF.  This is fairly
harmless.  A correct fix would involve saving the old %eflags (and
perhaps the old segment registers) where the user can't get at them.

988fa8efe3 Roll in my changes to make the cd9660 code understand the older
(original "High Sierra") CD format.  I've already implemented this for
1.1.5.1 (and posted to -hackers), but didn't get any response to it.
Perhaps i'm the only one who has such an old CD lying around...

Everything is done empirically, but i had three of them around (from
different vendors), so there's a high probability that i've got it
right. :)

87cf6d44c7 Add $Ids. Use DMA for downloading SCBs to the sequencer. Implement SDTR,
WDTR, and message reject handlers so they don't need to exist in the
sequencer.  All three of these cases are not on the critical path, so it
makes little sense to use up precious sequencer ram for them.

0d56403998 At $Ids to all files. Have the sequencer use DMA to tranfer its SCB
(SCSI control block) instead of having the host PIO it down.  Also
reimplement WDTR and SDTR optimization to remove code in the sequencer
and place the responsibility of knowing when to initiate SDTR or WDTR
on the kernel driver.  This vastly shortens the sequencer program yet
yeilds the same performance.

b60e6e6e9f Some fixes to device configuration, now that I've had a chance to do it
properly from the beginning:

	1) The `kern_devconf' struct should be a part of the driver's
	   `softc' structure (now it is).
	2) The `description' should say what the device actually is,
	   rather than just giving a model number (now it does).
	3) The device should be registered even if the probe fails, so
	   that it can be reconfigured later.
	4) For netifs, the device state should follow the IFF_UP flag.

Other network interfaces should follow this example.  (Please?)  Eventually
there should be a rundown routine doing the equivalent of setting IFF_UP
off, and perhaps more if warranted.

20415301cd Fix security holes in sigreturn(), ptrace() and procfs. sigreturn()
attempted to check for insecure and fatal eflags and segment
selectors, but missed many cases and got the IOPL check back to
front.  The other syscalls didn't check at all.

sys_process.c, machdep.c:
Only allow PT_WRITE_U to write to the registers (ordinary and FP).

psl.h, locore.s, machdep.c:
Eliminate PSL_MBZ, PSL_MBO and PSL_USERCLR.  We are not supposed
to assume anything about the reserved bits.  Use PSL_USERCHANGE
and PSL_KERNEL instead.  Rename PSL_USERSET to PSL_USER.

exception.s:
Define a private label for use by doreti when returning to user
mode fails.

machdep.c:
In syscalls, allow changing only the eflags that can be changed on
486's in user mode (no longer attempt to allow benign IOPL changes;
allow changing the nasty PSL_NT; don't allow changing the i586
bits).

Don't attempt to check all the cases involving invalid selectors
and %eip's.  Just check for privilege violations and let the invalid
things cause a trap.

procfs_machdep.c:
Call the ptrace register functions to do all the work for reading
and writing ordinary registers and for single stepping.

trap.c:
Ignore traps caused by PSL_NT being set.  Previously, users could
cause a fatal trap in user mode by setting PSL_NT and executing an
iret, and a fatal trap in kernel mode by setting PSL_NT and making
a syscall.  PSL_NT was cleared too late and not in enough modes to
fix the problem.

Make all traps in user mode (except T_NMI) nonfatal.

Recover from traps caused by attempting to load invalid user
registers in doreti by restarting the traps so that they appear to
occur in user mode.
---

Fix bogons that I noticed while fixing the above:

psl.h:
Fix some comments.

Uniformize idempotency ifdef.

exception.s, machdep.c:
Remove rsvd[0-14].  rsvd0 hasn't been reserved since the 486 came
out.  Replace rsvd0 by `align'.  rsvd[0-11] used wrong (magic
non-unique) trap numbers.  Replace rsvd[1-14] by rsvd.

locore.s:
Enable alignment check flag on 486's and 586's.

machdep.c:
Use a better type for kstack[].

Use TFREGP() to find the registers.

Reformat ptrace functions from SEF to something closer to KNF.

procfs_machdep.c:
The wrong pointer to the registers got fixed as a side effect.

Implement reading and writing of FP registers.

/proc/*/*regs now work (only) for processes that are in memory.

Clean up comments.

trap.c, trap.h:
Remove unused trap types.

9bf308efab Eliminate T_KDBTRAP, which will soon go away. It was only used for an
unreachable case label in kdb_trap().

Use the correct case labels in kdb_trap() so that normal ddb entry doesn't
print a message.

Change all printf's to db_printf's.  Now you can put a breakpoint at printf,
and ddb entry messages don't spam the syslog output.

Cosmetic:

Use ISPL() instead of magic numbers.

Don't compile the unused function kdb_kbd_trap().

Improve some asms.

Print the arg to Debugger().

dac0f2dbc1 Argl!, finally found this bummer. The code testing for a write-

submitted it didn't understand all the implications of calling
set_motor(), and the `who' who included the patch into the tree did it
blindly...  Pleeeeze, don't commit code to this driver unless you are
really going to understand what it does!  This one caused me to pull

Also reformat everything to fit into 80 columns again.

Changed my mind wrt. error reporting for a write-protected drive and
an open() with write intent; ENXIO has been too weird, now return EIO.
Some portions of the code need to be rewritten to use tprintf()

0d94caffca These changes embody the support of the fully coherent merged VM buffer cache,
much higher filesystem I/O performance, and much better paging performance. It
represents the culmination of over 6 months of R&D.

The majority of the merged VM/cache work is by John Dyson.

The following highlights the most significant changes. Additionally, there are
(mostly minor) changes to the various filesystem modules (nfs, msdosfs, etc) to
support the new VM/buffer scheme.

vfs_bio.c:
Significant rewrite of most of vfs_bio to support the merged VM buffer cache
scheme.  The scheme is almost fully compatible with the old filesystem
interface.  Significant improvement in the number of opportunities for write
clustering.

vfs_cluster.c, vfs_subr.c
Upgrade and performance enhancements in vfs layer code to support merged
VM/buffer cache.  Fixup of vfs_cluster to eliminate the bogus pagemove stuff.

vm_object.c:
Yet more improvements in the collapse code.  Elimination of some windows that
can cause list corruption.

vm_pageout.c:
Fixed it, it really works better now.  Somehow in 2.0, some "enhancements"
broke the code.  This code has been reworked from the ground-up.

vm_fault.c, vm_page.c, pmap.c, vm_object.c
Support for small-block filesystems with merged VM/buffer cache scheme.

pmap.c vm_map.c
Dynamic kernel VM size, now we dont have to pre-allocate excessive numbers of
kernel PTs.

vm_glue.c
Much simpler and more effective swapping code.  No more gratuitous swapping.

proc.h
Fixed the problem that the p_lock flag was not being cleared on a fork.

swap_pager.c, vnode_pager.c
Removal of old vfs_bio cruft to support the past pseudo-coherency.  Now the
code doesn't need it anymore.

machdep.c
Changes to better support the parameter values for the merged VM/buffer cache
scheme.

machdep.c, kern_exec.c, vm_glue.c
Implemented a seperate submap for temporary exec string space and another one
to contain process upages. This eliminates all map fragmentation problems
that previously existed.

ffs_inode.c, ufs_inode.c, ufs_readwrite.c
Changes for merged VM/buffer cache.  Add "bypass" support for sneaking in on
busy buffers.

f73f117cf0 Don't allow negative console numbers for the VT_WAITACTIVE ioctl. Use the
correct console number for the VT_WAITACTIVE ioctl.  Invalid console numbers
caused waiting on an invalid pointer.

Use bcopyw() instead of move_up() and move_down().  bcopyw() handles
overlapped copies and should be faster.  Actually use bcopy().  bcopy()
is slightly faster if video memory is 16-bit and about twice as fast if
it is 32-bit.  bcopy() is said to fail on someGA's, but syscons already
depends on it working for other accesses to video memory.

c4cab716b9 From Gene Stark:
If nd->swap_nblks is zero in nfs_mountroot(), then the system
       comes up without initializing swapdev_vp to an actual vnode pointer.
       The swap pager assumes a non-NULL value for swapdev_vp.

       is specified.

37e52b59cc Use sufficient parentheses in macros.
Remove bogus input operands for fnsave(), fnstcw() and fnstsw().

Change all fwait's to fnop's.  This might help avoid hardware bugs.
Wait after fninit with an fnop.  This should be safer now.

Fix some spelling and formatting errors.

Use natural sizes for control and status words (u_short, promotes to int).

Don't clobber the SWI_CLOCK_MASK bits in npx0_imask when using IRQ13.

Set the devconf state correctly (always busy, if configured).  Improve
code for npx_registerdev() a little (gcc can't keep id->id_unit in a
register for some reason).  Don't register a nonexistent npx device.

Print a useful message in npxattach() again (delete references to errors
and not the whole message).  Don't print "387 emulator" if there is no
emulator in the kernel.

Use %p for pointers in error messages.

Don't clobber the FPU state when there is an FPU exception.  Just clear
the exception flags (after saving the flags as before).  This allows
debuggers and SIGFPE handlers to look at the full exception state.
SIGFPE handlers should normally return via longjmp(), which restores a
good FPU state (as before).  Returning from a SIGFPE handler may leave
the FPU in the wrong state (as before).

Clear the busy latch _after_ clearing the exception flags so that there
is less chance of getting a bogus h/w interrupt for a control operation.

Clear the saved exception status word when the next FPU instruction is
excuted so that it doesn't stick around until the next exception.

Clear the busy latch after fnsave() in npxsave() in case it was set when
npxsave() was called.

dd4a485085 From Bill Paul:
- /sys/i386/i386/swapgeneric.c is just plain broke. But fear not, for I
  have unbroken it. One thing that swapgeneric.c does is walk through the
  list of configured devices searching for a boot device. The only easy
  way to accomplish this in 2.0 is to use Garret Wollman's kern_devconf
  stuff. *BUT*, the head of the kern_devconf linked list (dc_list) is declared
  static in /sys/kern/kern_devconf.c. This means that swapgeneric.c can't
  see it at link time. I had to remove the 'static' keyword to get around
  this little problem. I hope this doesn't break anything anywhere.

  *Furthermore,* there's a small matter of making the call to setconf()
  in swapgeneric.c disappear when 'config kernel swap generic' isn't used.
  You could change /sbin/config to create a dummy setconf() function in
  swapkernel.c, but that seems messy somehow. (It's also someting of an
  'it isn't broken, why are you fixing it' situation.) My solution was to
  do what the NetBSD people did and put an #ifdef GENERIC around the call
  to setconf(). If your kernel is called GENERIC or you define 'options
  GENERIC,' then you can use 'config kernel swap generic' and it'll work.

  That aside, the upshot is that: a) swapgeneric.c actually works, and
  and b) the -a boot flag now works as well. If you boot with -a, as in
  "Boot: wd(0,a)/kernel -a" you will be presented with a 'root device?'
  prompt after the autoconfig phase, at which point you can specify what
  device you want mounted as root. Regrettably, you can't specify an NFS
  filesystem. Yet. Three files are affected: /sys/i386/i386/swapgeneric.c,
  /sys/i386/i386/autoconf.c and /sys/kern/kern_devconf.c.

63c5d14d1b Miscellaneous changes from Bill Paul:
- /sys/i386/isa/if_ed.c doesn't quite know how to deal with SMC EtherEZ
  ethernet cards. The EtherEZ looks just like the Elite Ultra, except it
  has only 8K of shared memory. The only way to have it properly detected
  is to zero and test a few bytes of memory just about the first 8K region.
  If it clears properly, it's an Elite Ultra, otherwise it's an EtherEZ.

  I've also got an EtherEZ patch for netboot (Makefile, ether.c and ether.h).

- /sys/i386/isa/syscons.c wraps at the next to the last column rather than
  the last column, like it should. You don't really notice this unless you
  use certain programs that write all the way out to, say, the 80th column,
  like VMSmail. Along with a one-line fix for this are some changes to
  implement a non-blinking cursor. Put 'options "NOBLINK_CURSOR"' in your
  config file and give it a try. :)

10bfdf2bae From: "Serge V.Vakulenko" <vak@gw.cronyx.msk.su>
This is new version of Seagate ST01/02, Future Domain TMC-885, TMC-950
SCSI driver for FreeBSD.  I started from the 2.0R version and mostly
rewrote it.  New features are:

1) New probe algorithm.  Old driver read the BIOS region of the adapter
   memory and find the copyright string.  The problem was in the BIOS itself:
   it conflicted with IDE disks.  The solution was to unplug it and
   make the probe algorithm to work without it.
2) Proper timeout handling in numerous places where the driver
   polls waiting for some event.
3) Assembler flagments added in critical places, mostly for data transfer
   to of from the target.  It was possible to make it faster,
   but at the price of decreasing reliability.
4) Target-dependent delays when waiting for REQ deassert event.
   Some devices seem to be slower (CD-ROMS, some tape drives),
   and some seem to be too fast (disks).  The driver tests the REQ
   deassert timeout for each target and then uses it for polling.
5) Device flags added for SCSI parity control and sense request
   priority control.
6) Generic cleanup, after which the driver became much more readable
   (at least by me:).
7) Target data parity error logging is limited to avoid log file overflow.
8) Manual page added.

e72e8750d3 Insert a hook to initialize the serial port at the beginning of
boot().  This is needed so the "serialboot" stuff can share this file,

2c681fc102 This became a frequently requested item now.
The files in this directory are modified version of "biosboot".  The
only difference is in that they perform their I/O via a serial port,
so their preferrable usage is to form bootblocks for systems where the
kernel happens to have an "options COMCONSOLE".  Most of the code is
actually shared with "biosboot", and make will not (and should not)
descend into this directory by default.  It is in the responsibility
of the user to build these bootblocks instead of the original ones.

63e4f22a2a Fix numerous timestamp bugs.
DE_UPDATE was confused with DE_MODIFIED in some places (they do have
confusing names).  Handle them exactly the same as IN_UPDATE and
IN_MODIFIED.  This fixes chmod() and chown() clobbering the mtime
and other bugs.

DE_MODIFIED was set but not used.

Parenthesize macro args.

DE_TIMES() now takes a timeval arg instead of a timespec arg.  It was
stupid to use a macro for speed and do unused conversions to prepare
for the macro.

Restore the left shifting of the DOS seconds count by 1.  It got
lost among the shifts for the bitfields, so DOS seconds counts
appeared to range from 0 to 29 seconds (step 1) instead of 0 to 58
seconds (step 2).

Actually use the passed-in mtime in deupdat() as documented so that
utimes() works.

Change `extern __inline's to `static inline's so that msdosfs_fat.o
can be linked when it is compiled without -O.

Remove faking of directory mtimes to always be the current time.  It's
more surprising for directory mtimes to change when you read the
directories than for them not to change when you write the directories.
This should be controlled by a mount-time option if at all.
