e1765236c2 Remove bogus (caddr_t) casts from FREE macros; they can obscure serious
bugs that the type-checking would otherwise have found.  (This has no
effect on anything that I noticed in the current system other than finding
the bug in some code that I am writing.)

51823c3a93 If tcp_output() is unable to allocate space for a copy of the data waiting
to be sent, just clean up and return ENOBUFS rather than silently
proceeding without sending any of the data.  This makes it consistent
with the `#ifdef notyet' case immediately above.

832e06d4dc From Bruce Evans: (prototype related changes, other cleanups)
Add prototypes.  Use static for function definitions to match existing
prototypes.  Otherwise leave functions that should be static as extern.
TODO: declare everthing except sidriver and siintr as static.  I use
some new cdevs registration functions to do this for syscons and pcvt.

Fix siintr() to match its prototype in ioconf.c (don't return anything).
This may break the eisa support, but Julian says that eisa interrupts
never worked anyway.

(EISA support was never tested anyway - Peter)

a89f7290be Increased SOMAXCONN from 5 to 32. 5 was too small a value for just about
any reasonably busy machine, and by any measure is a lousy "max" value.
32 was chosen after a careful analysis of typical listen queue depths
on several busy Internet servers (both web and ftp). I also intend to
add a statistics counter for dropped connection requests due to the limit
being exceeded.

5e3e8d2b88 Generate prototypes for VOP functions. I decided to keep the old-style
definitions even though the functions are inline.  If vnode_if.h was
compiled by a non-ANSI compiler, then `inline' would be defined away,
so vnode_if.h might compile correctly.

e7451974bb Make pcvt and syscons live in the same kernel. If both are enabled, then
the first one in the config has priority.  They can be switched using
userconfig().

i386/i386/conf.c:
Initialize the shared syscons/pcvt cdevsw entry to `nx'.

Add cdevsw registration functions.

Use devsw functions of the correct type if they exist.

i386/i386/cons.c:
Add renamed syscons entry points to constab.

i386/i386/cons.h:
Declare the renamed syscons entry points.

i386/i386/machdep.c:
Repeat console initialization after userconfig() in case the current
console has become wrong.  This depends on cn functions not wiring down
anything important.

sys/conf.h:
Declare new functions.

i386/isa/isa.[ch]:
Add a function to decide which display driver has priority.  Should be
done better.

i386/isa/syscons.c:
Rename pccn* -> sccn*.

Initialize CRTC start address in case the previous driver has moved it.

i386/isa/syscons.c, i386/isa/pcvt/*
Initialize the bogusly shared variable Crtat dynamically in case the
stored value was changed by the previous driver.

Initialize cdevsw table from a template.

Don't grab the console if another display driver has priority.

i386/isa/syscons.h, i386/isa/pcvt/pcvt_hdr.h:
Don't externally declare now-static cdevsw functions.

i386/isa/pcvt/pcvt_hdr.h:
Set the sensitive hardware flag so that pcvt doesn't always have lower
priority than syscons.  This also fixes the "stupid" detection of the
display after filling the display with text.

i386/isa/pcvt/pcvt_out.c:
Don't be confused the off-screen cursor offset 0xffff set by syscons.

kern/subr_xxx.c:
Add enough nxio/nodev/null devsw functions of the correct type for syscons
and pcvt.

f2cb5630d0 cons.c:
Split off cdevsw initialization in cninit() into a new function
cninit_finish() that isn't called until all hardware device drivers
have been attached.  The bdevsw entry of the driver for the physical
console needs to be hooked after the physical driver has been
attached in case the attachment modified the entry.

Rearrange cninit() to avoid changing cn_tab until the driver for the
physical console has been initialized, so that the previous driver
(if any) can be used for debugging.

Start removing half-baked lint support.  bdevsw functions usually have
unused args but /*ARGSUSED*/ was used for only about 5% of them.

cons.h:
Declare cn_init_finish().

autoconf.c:
Call cn_init_finish().

Start adding prototypes.  Functions with bogus linkage (extern where
static is probably should be static) are explicitly declared as extern
so that the can be found easily (extern in a non-header is usually
wrong).

All:
Continue cleaning up init stuff: init functions shall be static;
INITs should be at the start of files...

6b435e575c Call output process in slstart() whether or not there is any output. As
in pppstart(), the output process may be overloaded to handle hardware
flow control and hardware output completions.

Don't wait for output to drain in slclose().  Discard output immediately.
New output is not prevented while processes are waiting for output to
drain (this is a bug), so the wait was sometimes forever.  Infinite
waits are also possible when CCTS_OFLOW is enabled and CTS is down.
Infinite waits were also caused by the above bug in slstart().

Start changing new init stuff yet again: rename unused arg `dummy'.

564643c636 More hacking on devfs..
I can  now do an mv on devices and directories in devfs
This was the hardest part.. link, delete and symlink will follow in
short order.
This code works but has definitly got vnode locking problems
I am electing to get the structure of it working before
spending too much time on the vnode confusion
so it's probably not reliable at the moment..
never-the less it looks good.

2bf07b2bd7 Patch to the atapi driver, by Serge V.Vakulenko, minor changes
by me...

Original message:

This patch upgrades the ATAPI CD-ROM driver to version 1.3.

It has three bugs fixed:

1) The `controller not ready' message at startup and later.
   It was caused by staled media change bit.

2) Incorrect shuffling of model string for some drives (NEC, Mitsumi).

3) Handling of drives which report itself as been of direct-access type,
   instead of CD-ROM type.

There is one known bug which is not fixed yet -- probing
in absense of IDE disks. A work-around exists though (thanks Steve!).
If you have no IDE disks attached, then remove them from the kernel
config file to make the CD-ROM attach correctly.
Unfortunately, there is no way to disable them from the kernel
interactive config mode.

fix a change where a shortcut resulted in teh wrong answer..

e.g.
touch a
touch b
mv a b
resulted in b being removed and a being moved to b

in the shortcut..
touch a
ln a b
mv a b
the wrong link was removed..
leaving a instead of b, giving a different result to when
both files were separate.
