99ec86e438 scgetc() referred to `spcl' in different ways when a key is pressed
and released.  It should use `spcl' consistently in both cases,
otherwise shift/control/alt state may not be correctly set/reset.

(Even with this fix, you can still make syscons confused and fail to
change internal state if you really want to, by installing a really
arcane and artificial keymap.)

ed1ab0dea2 Always mark st_ctime for update upon successful completion of
chown().  Previously, it wasn't marked for null chown()'s.  We
permit null chown()s as a special case of "appropriate privilege"
- everyone has enough priviilege to not change ids (this is a better
argument than the one I gave for rev.1.13, that null changes aren't
really changes).  However, POSIX.1 requires the update independently
of whether anything has changed.

Clear both the setuid and the setgid bits upon successful completion
of non-null chown()s by non-root.  Previously, the setuid bit was
only changed for non-null changes of the uid, etc.  POSIX.1 requires
clearing both unless the call was made by a process with "appropriate
privilege", in which case altering the bits is implementation-defined.
We define appropriate privilege as `process is root, or the change
is null', and the implementation-defined behaviour as not altering
the bits.   There is no interpretation that permits clearing only
one of the bits.

c38b4f3b91 (Part , after the Internet link broke totally yesterday.)
This is the long-threatened ISO 9660 CD-ROM bootstrap code.

This work has been sponsored by Plutotech International, Inc (who paid
the initial work), and interface business GmbH (where i did most of
the work).  A big thanks also goes to Bruce Evans, for his continuing
help and answering my stupid questions.

The code is basically functioning, with the following caveats:

. Rock Ridge attributes are not yet supported.
. Only SCSI CD-ROMs are supported, since i fail to see any possibility
  to determine the drive type using BIOS functions.  (Even for hard disks,
  this determination is done by a big hack only.)
. El Torito specifies a lot of crap and useless misfeatures, but crucial
  things like the ability to figure out the CD TOC have been ``forgotten''.
  Thus, if you wanna boot a multisession CD, you need to know at which CD
  block your session starts, and need to speciffy it using the @ clause.

. None of the CD-ROM controllers i've seen so far implements the full
  El Torito specification at all.  Adaptec is probably the closest, but
  they miss on non-emulation booting (which would be the most logical
  choice for us).  Thus, the current code bloats the 7.5 KB boot code
  up to 1.44 MB, in order to fake a `floppy' image.

  If you wanna use it, specify this file as the boot image on the
  command-line of the mksiosfs command (option -b).

  Caveat emptor: some versions of the Adaptec BIOS might even fail to
  access the CD-ROM at all, using the BIOS functions.  I think i've
  notice this for ver 1.26, the code has been tested with ver 1.23.

The boot string is as follows:

        [@sess-start] [filename] [-flags]

sess-start      Extend # where the last session starts, measured in
                CD-ROM blocks.

filename        As usual, but the input is case-insensitive by now
                (since we  don't grok RR anyway).

flags           As usual, but -C (use CDROM root f/s) is default, so
                specifying -C will decactivate this option (which is
                probably not what you want :).

A lot of cleanup work is probably required, and some of the files
could/should be merged back to biosboot, perhaps made conditional on
some #ifdef.  The malloc implementation that comes with cdboot might
also be useful for kzipboot.  (I needed a malloc() since the root dir
ain't fixed in size on a CD.)

I've been testing all this with a 2.2-STABLE as the base for biosboot.
I don't expect too many surprises, although i know the biosboot stuff
has been changed a lot in -current lately.  I'm sure Bruce will
comment on all this here anyway. :-)

2244ea07dc This is an upgrade so that the kernel supports the AIO calls from
POSIX.4.  Additionally, there is some initial code that supports LIO.
This code supports AIO/LIO for all types of file descriptors, with
few if any restrictions.  There will be a followup very soon that
will support significantly more efficient operation for VCHR type
files (raw.)  This code is also dependent on some kernel features
that don't work under SMP yet.  After I commit the changes to the
kernel to support proper address space sharing on SMP, this code
will also work under SMP.

1: cvs and cvsup don't really support vendor branches other than 1.1.1.x,
this is on 1.1.2.x and causing problems in cvsup 'checkout mode', just the
same as cvs has problems interpreting dates. (cvs has "1.1.1" hard coded)
2: cvs 'rm'ing them takes them off the vendor branch and should hide the
above problems.
3: it's just clutter until the merge is done.
4: if the problem isn't sufficiently resolved by taking these off the
vendor branch, the files will have to be nuked and re-imported.

66e39adc7c Fix a bug (apparently very old) that can cause a TCP connection to
be dropped when it has an unusual traffic pattern.  For full details
as well as a test case that demonstrates the failure, see the
referenced PR.

Under certain circumstances involving the persist state, it is
possible for the receive side's tp->rcv_nxt to advance beyond its
tp->rcv_adv.  This causes (tp->rcv_adv - tp->rcv_nxt) to become
negative.  However, in the code affected by this fix, that difference
was interpreted as an unsigned number by max().  Since it was
negative, it was taken as a huge unsigned number.  The effect was
to cause the receiver to believe that its receive window had negative
size, thereby rejecting all received segments including ACKs.  As
the test case shows, this led to fruitless retransmissions and
eventually to a dropped connection.  Even connections using the
loopback interface could be dropped.  The fix substitutes the signed
imax() for the unsigned max() function.

ac4c944d67 Fixes annoying behavior and a bug regarding the destructive
cursor (CHAR_CURSOR)

1. Reduced the number of calls to set_destructive_cursor().  The
destructive cursor produced noticeable overhead on the system.  It was
caused by draw_cursor_image() calling set_destructive_cursor() every
so often.

set_destructive_cursor() absolutely needs to be called when

a) the character code under the cursor has changed either because
   the cursor moved or because the screen was updated or the mouse
   pointer overlapped the cursor.
b) Or a new font has been loaded,
c) or the video mode has been changed,
d) or the cursor shape has been changed,
e) or the user switched virtual consoles.

2. Turn off the configuration flag CHAR_CURSOR (destructive cursor) in
scattach() if we have a non-VGA card.  The destructive cursor works
only for VGA.

3. Removed redundant calls to set_destructive_cursor() in some places.

4. Fixed the "disappearing mouse pointer" problem. The mouse pointer
looked hidden under the destructive cursor when it overlaped the cursor.

A slightly different version of the patch was reviewd and OKed by
sos and ache.

bf3c452e20 Add experimental APM support for some laptops.
If the configuration option PSM_HOOKAPM is defined and the APM device
is available, the psm driver will issue the ENABLE command to the
pointing device at the resume APM event if the device was open when
the system went into suspended mode. If the option
PSM_RESETAFTERSUSPEND is specified in addition to PSM_HOOKAPM, the
driver will try to reset the pointing device before sending the
ENABLE command.

Built-in PS/2-type pointing devices in some laptops (all the reports I
heard were about Toshiba models) sometimes don't work immediately
after the system is resumed. The device MAY become available after a
while. The system may exhibit the same symptom in other OS's too
(no, FreeBSD is not the only OS that is suffering :-).

I don't know the correct way of solving this yet, but it's been
reported that issuing the ENABLE command after resumption wakes up the
pointing device.

Without PSM_HOOKAPM, the psm driver behaves in the same way as before.

Problem reported in the bsd-nomads mailing list in Japan.

a2fc20d086 A fix/work-around for ThinkPad 535.
Add a new configuration flag, KBD_NORESET (0x20) to tell scprobe() not
to reset the keyboard.

IBM ThinkPad 535 has the `Fn' key with which the user can perform
certain functions in conjunction with other keys. For example, `Fn' +
PageUP/PageDOWN adjust speaker volume, `Fn' + Home/End change
brightness of LCD screen. It can also be used to suspend the system.

It appears that these functions are implemented at the keyboard level
or the keyboard controller level and totally independent from BIOS or
OS.  But, if the keyboard is reset (as is done in scprobe()), they
become unavailable.  (There are other laptops which have similar
functions associated with the `Fn' key. But, they aren't affected by
keyboard reset.)

ThinkPad 535 doesn't have switches or buttons to adjust brightness and
volume, or to put the system into the suspend mode. Therefore, it is
essential to preserve these `Fn' key functions in FreeBSD. The new
flag make scprobe() skip keyboard reset.

If this flag is not set, scprobe() behaves in the same say as before.

(If we only knew a way to detect ThinkPad 535, we could skip keyboard
reset automatically, but...)

de38397ecf Fix a condition where nfs_statfs() can precipitate a panic. There is
code that says this:

        nfsm_request(vp, NFSPROC_FSSTAT, p, cred);
        if (v3)
                nfsm_postop_attr(vp, retattr);
        if (!error)
                nfsm_dissect(sfp, struct nfs_statfs *, NFSX_STATFS(v3));

The problem here is that if error != 0, nfsm_dissect() will not be
called, which leaves sfp == NULL. But nfs_statfs() does not bail out
at this point: it continues processing until it tries to dereference
sfp, which causes a panic. I was able to generate this crash under
the following conditions:

1) Set up a machine as an NFS server and NFS client, with amd running
   (using NIS maps). /usr/local is exported, though any exported fs
   can can be used to trigger the bug.
2) Log in as normal user, with home directory mounted from a SunOS 4.1.3
   NFS server via amd (along with a few other NFS filesystems from same
   machine).
3) Su to root and type the following:
   # mount localhost:/usr/local /mnt
   # df

To fix the panic, I changed the code to read:

        if (!error) {
                nfsm_dissect(sfp, struct nfs_statfs *, NFSX_STATFS(v3));
        } else
                goto nfsmout;

This is a bit kludgy in that nfsmout is a label defined by the nfsm_subs.h
macros, but these macros are themselves more than a little kludgy. This
stops the machine from crashing, but does not fix the overall bug: 'error'
somehow becomes 5 (EIO) when a statfs() is performed on the locally mounted
NFS filesystem. This seems to only happen the first time the filesystem
is accesed: on subsequent accesses, it seems to work fine again.

Now, I know there's no practical use in mounting a local filesystem
via NFS, but doing it shouldn't cause the system to melt down.

0231d9ebb6 From the submitted patch :
The kernel with USERCONFIG_BOOT and VISUAL_USERCONFIG option presents
the user the kernel configuration menu upon boot.

The user can navigate the menu with cursor keys. I think it would be
nice if the user can navigate and select a menu item with regular keys
as well, so that the user who is using a serial console which is not
so capable of esc sequences still can choose a menu item.

With the following patch we can select an item by typing an item
number, 1, 2, or 3, or mnemonic `s' to skip UserConfig, 'v' to enter
the visual mode, and `c' to start the CLI mode. `p', `u', `n', and `d'
will move cursor up and down.

124ff4169d The syscons driver doesn't really check the presence of the display
adapter during the system boot. It always assumes there is at least a
monochrome adapter.

This is rather strange assumption. If there is no dispaly adapter, the
console driver cannot be any good...

In this patch, scinit() is split into two parts; the first part is
now called scvidprobe() which will detect the presence of video card
at the CGA or MONO buffer address and returns TRUE if found. It is
called during sccnprobe() and scprobe(). Both will fail if no video
card is found.

The second part, whose name stays the same as before, scinit(), is
called from sccninit() and scattach() to complete initialization of
the found video card.

The keyboard probe code is moved from scprobe() to sckbdprobe();
scprobe() now calls scvidprobe() and sckbdprobe() to carry out device
probe. (This is rather a cosmetic change, but it sure makes the code
look better organized.)

isn't the eventual fix for the locking problem.  Fine grained SMP
in the VM and VFS code will require (lots) more work.
