user-space programs without having to resort to opening /dev/io

In sppp_chap_input:
1) in the CHAP_CHALLENGE case don't output the peer's name if it is not
what we expected (DEBUG) since it will be printed out in the course
of events anyway.
2) in the CHAP_SUCCESS case test whether the peer is required to
authenticate himself [(sp->lcp.opts & (1 << LCP_OPT_AUTH_PROTO))],
otherwise the state machine may never switch into the network state.
I saw this case against 2 different ISPs; they never bothered to
authenticate themselves to me.

In sppp_pap_input:
in the PAP_ACK case do the same as in 2) above for the same reason.

Alexander Langer
7167d5b04c Convert caddr_t --> void * for sys/mman.h functions.
mlock, mmap, mprotect, msync, munlock, and munmap are defined by
POSIX as taking void *.  The const modifier has been added to
mlock, munlock, and mprotect as the standard dictates.

minherit comes from OpenBSD and has been updated to conform with
their recent change to void *.

madvise and mincore are not defined by POSIX, but their arguments
have been modified to be consistent with the POSIX-defined functions.
mincore takes a const pointer, but madvise does not due to the
MADV_FREE case.

58ffdf1d65 If available, use the device's LOGICAL blocksize as reported by
the "READ_CAPACITY" command, rather than the physical blocksize
reported in the physical geometry code-page.

Also don't print out worrying bogus messages when probing a
device that has no media. There's no point in printing out
something that is unknowable. It just confuses things.

Move the check for valid blocksize out of 'open()' to the subroutine
that actually finds this out, thus probe/attach can also report and
act on the problem.

the namespace pollution (others have been fixed).  The mbuf allocation

the malloc control values M_NOWAIT and M_WAITOK.  The mbuf values
are now defined directly.

64cfdf460e Restored used include of <sys/malloc.h>. malloc() is not used
here, but kmem_malloc() is used and it takes the same "flags" as
malloc().

Use the mbuf allocation "flags" M_WAIT and M_DONTWAIT consistently.
There is really only one boolean flag, M_DONTWAIT, but the "flags"
were always treated as enum-like values, except in some places here
where the values are tacitly converted to boolean flags.  Treat
them as enum-like values everywhere, except where we tacitly assume
that there are only two values in order to convert them to the
corresponding two kmem_malloc() "flags".

44099f9129 Fix some breakage that prevented the Plasmon burners from being used
under -current.  The actual preparation of the next track will now be
deferred until just before the first write operation.  Otherwise,
opening the device with write intent will cause the execution of
commands that are illegal in `limited command set mode' (i.e., after
the write channel has been opened).

While i was at it, cleaned up the worm_open() function a bit.

Removed the volume overflow pre-check in worm_strategy().  It was
time-consuming, and rather useless in many cases anyway (with the size
being reported for just the entire volume only), so we can as well let
the actual SCSI command fail instead, where it'll properly be reported
as EIO.

ea35435137 Made N_TXTADDR() work for kernels (assume that a ZMAGIC file with an
out of bounds a_entry is a kernel and use the usual kludge to find
the text address).  If gdb had used this, it would have been able
to find the kernel text address properly.  Unfortunately, it uses
its own a.out macros, so this is mainly an example for gdb to copy.

1cbbd625cc Add support for poll(2) on files. vop_nopoll() now returns POLLNVAL
if one of the new poll types is requested; hopefully this will not break
any existing code.  (This is done so that programs have a dependable
way of determining whether a filesystem supports the extended poll types
or not.)

The new poll types added are:

	POLLWRITE - file contents may have been modified
	POLLNLINK - file was linked, unlinked, or renamed
	POLLATTRIB - file's attributes may have been changed
	POLLEXTEND - file was extended

Note that the internal operation of poll() means that it is impossible
for two processes to reliably poll for the same event (this could
be fixed but may not be worth it), so it is not possible to rewrite
`tail -f' to use poll at this time.

8256655132 After one of my analysis passes to evaluate methods for SMP TLB mgmt, I
noticed some major enhancements available for UP situations.  The number
of UP TLB flushes is decreased much more than significantly with these
changes.  Since a TLB flush appears to cost minimally approx 80 cycles,
this is a "nice" enhancement, equiv to eliminating between 40 and 160
instructions per TLB flush.

Changes include making sure that kernel threads all use the same PTD,
and eliminate unneeded PTD switches at context switch time.

80987b7a3b Fixed EOF handing.
1. SS_CANTRCVMORE was initially set on the wrong socket, so reads
when there has never been a writer on the socket did not return 0.
Note that such reads are only possible if the fifo was opened in
(O_RDONLY | O_NONBLOCK) mode.

2. SS_CANTSENDMORE was initially set on the wrong socket, but this
was harmless because the wrong socket is never sent from and there
is no need to set the flag initially on the right socket (since open
in (O_WRONLY | O_NONBLOCK) mode fails if there is no reader...).

3. SS_CANTRCVMORE was cleared when read() returns.  This broke the
case where read() returns 0 - subsequent reads are supposed to
return 0 until a writer appears.  There is no need to clear the
flag when read() returns, since it is cleared correctly when a
writer appears.

with 'controller pnp0' or *ANY* other PnP devices.  If you use some other
PnP devices, enabling css0 will burn your house down. :-]  The
"simplified" PnP init sequence directly blats your config(8) settings onto

area desperately needs a cleanup.

Yes -- I know that this is NOT the right way to fix it.  But I haven't
been able to get it to panic yet (which confuses me).  I am going to
be looking into the vgone() code now, as that may be a part of it.

c6d1bed112 - Add support for the following mice to psm/moused/sysmouse:
MS IntelliMouse, Kensington Thinking Mouse, Genius NetScroll,
  Genius NetMouse, Genius NetMouse Pro, ALPS GlidePoint, ASCII
  MieMouse, Logitech MouseMan+, FirstMouse+

- The `psm' driver is made to recognize various models of PS/2 mice
and enable their extra features so that their additional buttons and
wheel/roller are recognized. The name of the detected model will be
printed at boot time.

- A set of new ioctl functions are added to the `psm', `mse' and
`sysmouse' drivers so that the userland program (such as the X server)
can query device information and change driver settings.

- The wheel/roller movement is handled as the `Z' axis movement by the
mouse drivers and the moused daemon. The Z axis movement may be mapped
to another axis movement or buttons.

- The mouse drivers support a new, standard mouse data format,
MOUSE_PROTO_SYSMOUSE format which can encode x, y, and x axis movement
and up to 10 buttons.

/sys/i386/include/mouse.h
- Added some fields to `mousestatus_t' to store Z axis movement
  and flag bits.
- Added the field `model' to `mousehw_t' to store mouse model code.
  Defined model codes.
- Extended `mousemode_t'.
- Added new protocols and some constants for them.
- Added new ioctl functions and structures.
- Removed obsolete ioctl definitions.

/sys/i386/include/console.h
- Added `dz' field to the structure `mouse_data' to pass Z axis movement
  to `syscons/sysmouse'.
- Removed LEFT_BUTTON, MIDDLE_BUTTON and RIGHT_BUTTON.  Use button bits
  defined in `mouse.h' instead.

/sys/i386/isa/psm.c
- Added a set of functions to detect various mice which have additional
  features (wheel and buttons) unavailable in the standard PS/2 mouse.
- Refined existing ioctl functions and added new ones.  Most important
  of all is MOUSE_SETLEVEL which manipulates the output level of the driver.
  While the output level remains zero, the output from the `psm' driver is
  in the standard PS/2 mouse format (three bytes long).  When the level
  is set to one, the `psm' driver will send data in the extended format.
  At the level two the driver uses the format which is native to the
  connected mouse is used. (Meaning that the output from the device is
  passed to the caller as is, unmodified.)  The `psm'  driver will pass
  such extended data format as is to the caller if the output level is
  two, but emulates the standard format if the output level is zero.
- Added kernel configuration flags to set initial resolution
  (PSM_CONFIG_RESOLUTION) and acceleration (PSM_CONFIG_ACCEL).
- Removed the compile options PSM_ACCEL, PSM_CHECKSYNC and PSM_EMULATION.
  Acceleration ratio is now specified by the kernel configuration flags
  stated above.  Sync check logic is refined and now standard.
  The sync check can be turned off by the new kernel configuration flags
  PSM_CONFIG_NOCHECKSYNC (0x100).  PSM_EMULATION has been of little use.
- Summer clean up :-)  Removed unused code and obsolete comments.

/sys/i386/isa/mse.c
- Created mseioctl() to deal with ioctl functions MOUSE_XXXX.
  Most importantly, the MOUSE_SETLEVEL ioctl will change the
  output format from the 5 byte format to the new, extended format
  so that the caller can take advantage of Z axis movement and additional
  buttons.
- Use constants defined in `mouse.h' rather than magic numbers.

/sys/i386/isa/syscons.c
- Changed scioctl() to reflect the new `console.h' and some of the new
  ioctls defined in `mouse.h'.  Most importantly, the MOUSE_SETLEVEL
  ioctl will change the `sysmouse' output format from the MouseSystems
  5 byte format to the new, extended format so that the caller can
  take advantage of Z axis movement and additional buttons.
- Added support for double/triple click actions of the left button and
  single click action of the right button in the virtual console.  The
  left button double click will select a word under the mouse pointer.
  The triple click will select a line and the single click of the right
  button will extend the selected region to the current position of
  the mouse pointer.  This will make the cut/paste support more compatible
  with xterm.

/sys/i386/isa/kbdio.h
- Added PSM_INTELLI_ID.

91241944ea Added a kernel-only error code ENOICTL. This will be returned from
low level ioctl routines instead of the magic number -1 so that
callers can distinguish it from ERESTART (which happens to be -1).
-1 meant that the ioctl was not handled at the called level.
ERESTART is normal when a sleeping ioctl is interrupted.  ERESTART
got converted to ENOTTY instead of restarting the ioctl.  Many
(most?) ioctls can not be restarted safely, but this is apparently
supposed to be handled by drivers converting ERESTART to EINTR.
I first saw this problem for TIOCDRAIN.  Justin saw if for disk
ioctls.

 1 < n < inf.

If paging heavily on large systems, it is likely that a performance
improvement can be achieved by increasing the parameter.  On a large
system, the parm is 32, but numbers as large as 128 can make a big
difference.  If paging is expensive, you might try decreasing the
number to 1-8.

84af4da65a Finish up the vast majority of the AIO/LIO functionality. Proper signal
support was missing in the previous version of the AIO code.  More
tunables added, and very efficient support for VCHR files has been added.
Kernel threads are not used for VCHR files, all work for such files is
done for the requesting process directly.  Some attempt has been made to
charge the requesting process for resource utilization, but more work
is needed.  aio_fsync is still missing (but the original fsync system
call can be used for now.)  aio_cancel is essentially a noop, but that
is okay per POSIX.  More aio_cancel functionality can be added later,
if it is found to be needed.

The functions implemented include:
	aio_read, aio_write, lio_listio, aio_error, aio_return,
	aio_cancel, aio_suspend.

The code has been implemented to support the POSIX spec 1003.1b
(formerly known as POSIX 1003.4 spec) features of the above.  The
async I/O features are truly async, with the VCHR mode of operation
being essentially the same as physio (for appropriate files) for
maximum efficiency.  This code also supports the signal capability,
is highly tunable, allowing management of resource usage, and
has been written to allow a per process usage quota.

Both the O'Reilly POSIX.4 book and the actual POSIX 1003.1b document
were the reference specs used.  Any filedescriptor can be used with
these new system calls.  I know of no exceptions where these
system calls will not work.  (TTY's will also probably work.)

61ca849927 From the author:
Here are the remanding changes required to support the Ensoniq
Soundscape using FreeBSD 3.0-current.

Notes:

  1) ad1848_init already has code to detect if DMA_DUPLEX should
     be set so it is not necessary (and is in fact a mistake) to
     hard code setting it.  Not all soundcards (i.e. the current
     sscape driver) are capable of using DMA_DUPLEX.

  2) The other changes are hopefully self explanatory.  Feel free
     to let me know if you need additional information.
