9246df9bb4 strtol and atoi VERY broken in 8bit chars locale, i.e. if you pass something
like 38400<any 8bit char, isalpha> it not detect this stuff and
produce very big number instead. Fixed by operating with unsigned char
and checking for isascii. (secure/telnetd hits by it f.e.)

21cc29328e Removed my special-case hack for VOP_LINK and fixed the problem with the
wrong vp's ops vector being used by changing the VOP_LINK's argument order.
The special-case hack doesn't go far enough and breaks the generic
bypass routine used in some non-leaf filesystems. Pointed out by Kirk
McKusick.

17d6fa2126 Sleep on a better address to wait for output to drain out of the

than a small chance that the sleep address is actually used (this
used to work by timing out).  Don't bother clearing the sleep-on
flag after a timeout here or elsewhere since leaving it set just
generates a few null calls to wakeup().

6161be8527 Obtained from: partly from ancient patches of mine via 1.1.5
Introduce TS_CONNECTED and TS_ZOMBIE states.  TS_CONNECTED is set
while a connection is established.  It is set while (TS_CARR_ON or
CLOCAL is set) and TS_ZOMBIE is clear.  TS_ZOMBIE is set for on to
off transitions of TS_CARR_ON that occur when CLOCAL is clear and
is cleared for off to on transitions of CLOCAL.  I/o can only occur
while TS_CONNECTED is set.  TS_ZOMBIE prevents further i/o.

Split the input-event sleep address TSA_CARR_ON(tp) into TSA_CARR_ON(tp)
and TSA_HUP_OR_INPUT(tp).  The former address is now used only for
off to on carrier transitions and equivalent CLOCAL transitions.
The latter is used for all input events, all carrier transitions
and certain CLOCAL transitions.  There are some harmless extra
wakeups for rare connection- related events.  Previously there were
too many extra wakeups for non-rare input events.

Drivers now call l_modem() instead of setting TS_CARR_ON directly
to handle even the initial off to on transition of carrier.  They
should always have done this.  l_modem() now handles TS_CONNECTED
and TS_ZOMBIE as well as TS_CARR_ON.

gnu/isdn/iitty.c:
Set TS_CONNECTED for first open ourself to go with bogusly setting
CLOCAL.

i386/isa/syscons.c, i386/isa/pcvt/pcvt_drv.c:
We fake carrier, so don't also fake CLOCAL.

kern/tty.c:
Testing TS_CONNECTED instead of TS_CARR_ON fixes TIOCCONS forgetting to
test CLOCAL.  TS_ISOPEN was tested instead, but that broke when we disabled
the clearing of TS_ISOPEN for certain transitions of CLOCAL.

Testing TS_CONNECTED fixes ttyselect() returning false success for output
to devices in state !TS_CARR_ON && !CLOCAL.

Optimize the other selwakeup() call (this is not related to the other
changes).

kern/tty_pty.c:
ptcopen() can be declared in traditional C now that dev_t isn't short.

fc2f9d9828 Assorted cosmetic changes:
Make more functions static.

tty.c:
Use tcflag_t (u_long) and cc_t instead of u_char and int/long.

Don't record values that are only evaluated once.

Compare ints using imin(), not min().  min() is for comparing u_ints.
Old versions of tty.c used the type-safe but multiple-evaluation-unsafe
macro MIN().  The args are apparently never negative; otherwise this
change would be non-cosmetic.

Don't repeat the loop test in ttywait().

tty.h:
Improve English in and formatting of comments.

105a5302c8 Improve input flow control.
Use input buffer watermarks of TTYHOG-512 (high) and (high)*7/8
(low) instead of TTYHOG/2 (high) and TTYHOG/5 (low) to agree with
some drivers.  512 is magic and some things depended on TTYHOG/2
>= TTYHOG-512 to work; now they depend on the 512 magic not changing
and TTYHOG-512 being significantly larger than 0.  This should be
handled in ttsetwater().

Separate the decision about whether to do input flow control from
doing it.  ttyblock() now just starts input flow control (hardware
and/or software) and there is a new function ttyunblock() to stop
it.  The decisions are the same except for the watermark changes
and allowing for input expansion for PARMRK.

When flushing input, try harder at first to send a start character
if required, but give up if the first attempt fails.

cy.c, rc.c, sio.c:
Simplify: let ttyinput() handle input flow control if it is not
being bypassed.  Use ttyblock() to start flow control otherwise.

rc.c:
Use same input flow control test as elsewhere: test in a more
efficient order and start flow control at >= highwater instead of
at > highwater.

8169a9d300 The other day someone brought me an old Apple Laserwriter II with a serial
interface set at 57600 baud, and I found out the hard way that lpd doesn't
know about speeds greater than 38400, even though <sys/ttydev.h> also
permits 57600 and 115200 baud. Fix this by adding B57600 and B115200 to the
'bauds' table. (The Apple printer worked properly once I did this, BTW. :)

b6ccb9009a Fix panic("ifpromisc failed") when shutting down a bpf tap when the attached
interface is no longer IFF_UP.
The test for IFF_UP in ifpromisc is only useful while enabling IFF_PROMISC
and the higher levels of the bpf code do not allow for the possibility of
failure while shutting down.  This is a trivial change.
Also, fixes PR#522.

08d1bb1b89 Fix the sysctl string routines to return as much of the
string as possible and return ENOMEM if the entire string cannot
be returned.  This brings the routines in line with how the man
page says they work, and how the calling routines are expecting
them to work.  This allows the dummy uname() routine in libc to
obtain the version string, since the kernel version string is
longer than that normally returned by the uname() routine.
This is 3/4 of the fix for PR# 462.

b772633f52 Fix various kernfs file system problems, which can result in
umountable file systems, hung processes, or system panics:

- Some operations could return without decrementing the vnode
  reference count.
- Some operations could leave the vnode locked.
- Generalize the /kern/rootdev & rrootdev files so that they
  are no longer special cased in kernfs_lookup().

Note: procfs, fdescfs, and most of the other miscfs/* file systems
also suffer from the same type of problems and I will work on
fixing them one at a time.

3029c788af Ignore trailing slashes in pathnames that "refer to a directory",
as is required to be POSIXLY_CORRECT and "right".  I interpret
"referring to a directory" as being a directory or becoming a
directory.  E.g., the trailing slashes in mkdir("/nonesuch/"),
rename("/tmp", /nonesuch/") and link("/tmp", "/root_can_like_dirs/")
are ignored because the target will become a directory if the
syscall succeeds.  A trailing slash on a symlink causes the symlink
to be followed (this is a bug if the symlink doesn't point to a
directory; fix later).

f128be1e30 Don't swap the queue headers to implement concatenation of the
queues for TIOCSETA[W].  Swapping an even number of times broke
the queue resource limits.  This would have broken CRTSCTS flow
control if the clist slush list was used up.

Don'concatenate the queues for TIOCSETA[W] if one of the queues
has a resource limit of 0.  Concatenation would cause a panic if
one of the queues is nonempty and the other is limited to length
0.  This may have caused panics in PPPDISC.

Wake up readers after all transitions of ICANON.  When ICANON is
turned off it is quite likely that characters will become available
to be read.
