As (briefly) discussed on current-users, change the way that MAKEDEV checks
for more than one of the  -m -p -s -t args (and checks whether any were given
to pick one if not) to be more shell friendly.

Note that while the method here is the same as was discussed on the list,
the actual implementation is free of the typos, and just pure lunacy that
was in the code that was shown there.

Also note these changes are intended to be completely internal, there
should be no visible impact upon the way that MAKEDEV works.

s/filesystem/file system/

Thanks to Thomas for pointing out that in NetBSD man pages we try to use the convention of writing it
as "file system".

(abhinav)

A better LINENO implementation.  This version deletes (well, #if 0's out)
the LINENO hack, and uses the LINENO var for both ${LINENO} and $((LINENO)).
(Code to invert the LINENO hack when required, like when de-compiling the
execution tree to provide the "jobs" command strings, is still included,
that can be deleted when the LINENO hack is completely removed - look for
refs to VSLINENO throughout the code.  The var funclinno in parser.c can
also be removed, it is used only for the LINENO hack.)

This version produces accurate results: $((LINENO)) was made as accurate
as the LINENO hack made ${LINENO} which is very good.  That's why the
LINENO hack is not yet completely removed, so it can be easily re-enabled.
If you can tell the difference when it is in use, or not in use, then
something has broken (or I managed to miss a case somewhere.)

The way that LINENO works is documented in its own (new) section in the
man page, so nothing more about that, or the new options, etc, here.

This version introduces the possibility of having a "reference" function
associated with a variable, which gets called whenever the value of the
variable is required (that's what implements LINENO).  There is just
one function pointer however, so any particular variable gets at most
one of the set function (as used for PATH, etc) or the reference function.
The VFUNCREF bit in the var flags indicates which func the variable in
question uses (if any - the func ptr, as before, can be NULL).

I would not call the results of this perfect yet, but it is close.

(kre)

An initial attempt at implementing LINENO to meet the specs.

Aside from one problem (not too hard to fix if it was ever needed) this version
does about as well as most other shell implementations when expanding
$((LINENO)) and better for ${LINENO} as it retains the "LINENO hack" for the
latter, and that is very accurate.

Unfortunately that means that ${LINENO} and $((LINENO)) do not always produce
the same value when used on the same line (a defect that other shells do not
share - aside from the FreeBSD sh as it is today, where only the LINENO hack
exists and so (like for us before this commit) $((LINENO)) is always either
0, or at least whatever value was last set, perhaps by
LINENO=${LINENO}
which does actually work ... for that one line...)

This could be corrected by simply removing the LINENO hack (look for the string
LINENO in parser.c) in which case ${LINENO} and $((LINENO)) would give the
same (not perfectly accurate) values, as do most other shells.

POSIX requires that LINENO be set before each command, and this implementation
does that fairly literally - except that we only bother before the commands
which actually expand words (for, case and simple commands).  Unfortunately
this forgot that expansions also occur in redirects, and the other compound
commands can also have redirects, so if a redirect on one of the other compound
commands wants to use the value of $((LINENO)) as a part of a generated file
name, then it will get an incorrect value.  This is the "one problem" above.
(Because the LINENO hack is still enabled, using ${LINENO} works.)

This could be fixed, but as this version of the LINENO implementation is just
for reference purposes (it will be superseded within minutes by a better one)
I won't bother.  However should anyone else decide that this is a better choice
(it is probably a smaller implementation, in terms of code & data space then
the replacement, but also I would expect, slower, and definitely less accurate)
this defect is something to bear in mind, and fix.

This version retains the *BSD historical practice that line numbers in functions
(all functions) count from 1 from the start of the function, and elsewhere,
start from 1 from where the shell started reading the input file/stream in
question.  In an "eval" expression the line number starts at the line of the
"eval" (and then increases if the input is a multi-line string).

Note: this version is not documented (beyond as much as LINENO was before)
hence this slightly longer than usual commit message.

Fix the trailing space in the probe specifier's name in dtrace(1)'s output.

When using dtrace using one of the tracing options, such as -n, -P, -i, -f etc.,
the first line of output from dtrace one is something like this:

sudo dtrace -n 'syscall:::entry /pid == 100/ {@num[probefunc] = count();}'
dtrace: description 'syscall:::entry ' matched 482 probes

There is a trailing space at the end of the probe specifier name ('syscall:::entry ').
This happens beucase dtrace tries to separate the probe name from the predicate and actions
using `{' and `/' as the separators but doesn't consider space also as a possible separator.

Output after this change:
sudo dtrace -n 'syscall:::entry /pid == 100/ {@num[probefunc] = count();}'
dtrace: description 'syscall:::entry' matched 482 probes

Make cd (really) do cd -P, and not just claim that is what it is doing
while doing a half-hearted, broken, partial, version of cd -L instead.
The latter (as the manual says) is not supported, what's more, it is an
abomination, and should never be supported (anywhere.)
Fix the doc so that the pretense that we notice when a path given crosses
a symlink (and turns on printing of the destination directory) is claimed
no more (that used to be true until late Dec 2016, but was changed).  Now
the print happens if -o cdprint is set, or if an entry from CDPATH that is
not "" or "." is used (or if the "cd dest repl" cd cmd variant is used.)
Fix CDPATH processing: avoid the magic '%' processing that is used for
PATH and MAILPATH from corrupting CDPATH.  The % magic (both variants)
remains undocumented.
Also, don't double the '/' if an entry in PATH or CDPATH ends in '/'
(as in CDPATH=":/usr/src/").  A "cd usr.bin" used to do
chdir("/usr/src//usr.bin").  No more.  This is almost invisible,
and relatively harmless, either way....
Also fix a bug where if a plausible destination directory in CDPATH
was located, but the chdir() failed (eg: permission denied) and then
a later "." or "" CDPATH entry succeeded, "print" mode was turned on.
That is:
cd /tmp; mkdir bin
mkdir -p P/bin; chmod 0 P/bin
CDPATH=/tmp/P:
cd bin
would cd to /tmp/bin (correctly) but print it (incorrectly).
Also when in "cd dest replace" mode, if the result of the replacement
generates '-' as the path named, as in:
cd $PWD -
then simply change to '-' (or attempt to, with CDPATH search), rather
than having this being equivalent to "cd -")
Because of these changes, the pwd command (and $PWD) essentially
always acts as pwd -P, even when called as pwd -L (which is still
the default.)  That is, even more than it did before.
Also fixed a (kind of minor) mem management error (CDPATH related)
"whosoever shall padvance must stunalloc before repeating" (and the
same for MAILPATH).
--
If we are going to keep the MAILPATH % hack, then at least do something
rational.  Since it isn't documented, what "rational" is is up for
discussion, but what it did before was not it (it was nonsense...).

Fix buggy dhcrelay(8) requirement to stay in foreground

This version of dhcrelay(8) needed to stay inforeground with -d flag in
order to service requests. Running inbackground turned it deaf to DHCP
requests.

This was caused by wrong kqueue(2) usage, where kevent(2) was used with
a file descriptor obtained by a kqueue(2) call done before fork(2).
kqueue(2) man page says "The queue is not inherited by a child created
with fork(2)". As a result, kevent(2) calls always got EBADF.

The fix is to reorder function calls in dhcrelay(8) main() function.
dhcp_context_create(), which causes kqueue(2) to be invoked, is
moved with its dependencies after fork(2). This matches the code layout
of dhclient(8) and dhcpd(8), which do not have the bug.

The fix was not submitted upstream since latest ISC DHCP code was
refactored and does not have the bug anymore.

The latter (as the manual says) is not supported, what's more, it is an
abomination, and should never be supported (anywhere.)

Fix the doc so that the pretense that we notice when a path given crosses
a symlink (and turns on printing of the destination directory) is claimed
no more (that used to be true until late Dec 2016, but was changed).  Now
the print happens if -o cdprint is set, or if an entry from CDPATH that is
not "" or "." is used (or if the "cd dest repl" cd cmd variant is used.)

Fix CDPATH processing: avoid the magic '%' processing that is used for
PATH and MAILPATH from corrupting CDPATH.  The % magic (both variants)
remains undocumented.

Also, don't double the '/' if an entry in PATH or CDPATH ends in '/'
(as in CDPATH=":/usr/src/").  A "cd usr.bin" used to do
chdir("/usr/src//usr.bin").  No more.  This is almost invisible,
and relatively harmless, either way....

Also fix a bug where if a plausible destination directory in CDPATH
was located, but the chdir() failed (eg: permission denied) and then
a later "." or "" CDPATH entry succeeded, "print" mode was turned on.
That is:
cd /tmp; mkdir bin
mkdir -p P/bin; chmod 0 P/bin
CDPATH=/tmp/P:
cd bin
would cd to /tmp/bin (correctly) but print it (incorrectly).

Also when in "cd dest replace" mode, if the result of the replacement
generates '-' as the path named, as in:
cd $PWD -
then simply change to '-' (or attempt to, with CDPATH search), rather
than having this being equivalent to "cd -")

Because of these changes, the pwd command (and $PWD) essentially
always acts as pwd -P, even when called as pwd -L (which is still
the default.)  That is, even more than it did before.

Also fixed a (kind of minor) mem management error (CDPATH related)
"whosoever shall padvance must stunalloc before repeating" (and the
same for MAILPATH).

Add a 1MB mapping to the MMU init table to cover the FDT blob in case the
bootloader places it beyond the init mem size.

- prevent optimization from omitting the frame pointer (and re-using it);
  we use it in our inline assembly.
- convert to c a little assembly to make the code more understandable.

(christos)

Re-introduce support for multi-block transfers and split transfers to fit
within the 65535-byte limit.

(jmcneill)

Give a hint to controllers in the command flags if we are performing a
transfer with an SDHC capable card. If the controller needs to adjust
command args, it can use this hint to understand how it is encoded.

Operations fstrans_start() and fstrans_start_nowait() now always
use FSTRANS_SHARED as lock type so remove the lock type argument.

File system state FSTRANS_SUSPENDING is now unused so remove it.

Locking a layer vnode using the regular bypass routine is no longer
racy.  Undo the change from 2017-03-30 11:16:52, commitid eurqbzuGxGRlryLz

Now that FSTRANS is part of VOP_*LOCK() remove FSTRANS and vdead_check()
from genfs_.*lock() and assert the vnode state once the vnode is locked.

(hannken)

Regen.

(hannken)

Add "FSTRANS=LOCK" and "FSTRANS=UNLOCK" to vop_lock and vop_unlock.

Add two "static inline" functions to vnode_if.c to handle MPSAFE
and FSTRANS before and after the "VCALL()".

Take FSTRANS and handle error before "VCALL(...vop_lock...)" and
release it after "VCALL(...vop_unlock...)".

(hannken)

A vnode is usually called "active", if it has an associated file system
node and a usecount greater zero.  Therefore rename state "VS_ACTIVE"
to "VS_LOADED" and add a new synthetic state "VS_ACTIVE" for VSTATE_ASSERT()
to assert an active vnode.

Add VSTATE_ASSERT_UNLOCKED() to be used with v_interlock unheld and
move the state assertion macros to sys/vnode_impl.h.

NFC: Code style only.  Rather than being perverse and adding the

Fix typo: s/interrput/interrupt/

The correct usage of recordregion() is (begin, end) not (begin, length).

Fixing this fixes a regression introduced earlier today (UTC) where
arithmetic expressions would be split correctly when the arithmetic
started at the beginning of a word:
echo $(( expression ))
where "begin" is 0, and so (begin, length) is the same as (begin, begin+length)
(aka: (begin,end) - and yes, "end" means 1 after last to consider).
but did not work correctly when the usage was
echo XXX$( expression ))
(begin !+ 0) and would only split (some part of) the result of the expression.

This regression was also foung by the new t_fsplit:split_arith
test case added earlier to the ATF tests for sh.

(kre)

When we record an arithmetic expression ($(( ))) as being quoted,
what matters is the quoting state just before we switch into arithmetic
syntax parsing mode, not the state after...

This fixes the regiression introduced earlier today (UTC) where
quoted arithmetic expressions were being subjected to word splitting.
