c1564db05d sh: Recognize "--" in . and exec.
Although "--" historically has not been required to be recognized for
certain special builtins that do not take options in POSIX, some other
implementations recognize options for them, requiring scripts to use "--" or
avoid operands starting with "-".

Operands starting with "-" can be avoided with eval by prepending a space,
and cannot occur with break, continue, exit, return and shift as they only
take numbers, nor with times as it does not take operands. With . and exec,
avoiding "-" is not so easy as it may require reimplementing the PATH
search; therefore the current proposal for POSIX is to require recognition
of "--" for them.

We continue to accept other strings starting with "-" as operands to . and
exec, and also "--" if it is alone to . (which would otherwise be invalid
anyway).

1f65c541e8 sh: Reap any zombies before forking for a background command.
This prevents accumulating huge amounts of zombies if a script executes
many background commands but no external commands or subshells.

Note that zombies will not be reaped during long calculations (within
the shell process) or read builtins, but those actions do not create
more zombies.

The terminated background commands will also still be remembered by the
shell.

4710b07ecf sh: Fix pathname expansion with quoted slashes like *\/.
These are git commits 36f0fa8fcbc8c7b2b194addd29100fb40e73e4e9 and
d6d06ff5c2ea0fa44becc5ef4340e5f2f15073e4 in dash.

Because this is the first code I'm importing from dash to expand.c, add the
Herbert Xu copyright notice which is in dash's expand.c.

When pathname expanding *\/, the CTLESC representing the quoted state was
erroneously taken as part of the * pathname component. This CTLESC was then
seen by the pattern matching code as escaping the '\0' terminating the
string.

The code is slightly different because dash converts the CTLESC characters
to backslashes and removes all the other CTL* characters to allow
substituting glob(3).

The effect of the bug was also slightly different from dash (where nothing
matched at all). Because a CTLESC can escape a '\0' in some way, whether
files were included despite the bug depended on memory that should not be
read. In particular, on many machines /*\/ expanded to a strict subset of
what /*/ expanded to.

Example:
  echo /*"/null"

This should print /dev/null, not /*/null.

e4b50334ec sh: Apply locale vars on builtins, recognize LC_MESSAGES as a locale var.
This allows doing things like LC_ALL=C some_builtin to run a builtin under a
different locale, just like is possible with external programs. The
immediate reason is that this allows making printf(1) a builtin without
breaking things like LC_NUMERIC=C printf '%f\n' 1.2

This change also affects special builtins, as even though the assignment is
persistent, the export is only to the builtin (unless the variable was
already exported).

Note: for this to work for builtins that also exist as external programs
such as /bin/test, the setlocale() call must be under #ifndef SHELL. The
shell will do the setlocale() calls which may not agree with the environment
variables.

dc00aa5dd6 ln: Allow a trailing slash when creating a link to a directory.
In the 'ln source... directory' synopsis, the basename of each source
determines the name of the created link. Determine this using basename(3)
instead of strrchr(..., '/') which is incorrect if the pathname ends in a
slash.

The patch is somewhat changed to allow for basename(3) implementations that
change the passed pathname, and to fix the -w option's checking also.
The code to compare directory entries only applies to hard links, which
cannot be created to directories using ln.

Example:
  ln -s /etc/defaults/ /tmp
This should create a symlink named defaults.

634e9188af sh: Do tilde expansion in substitutions.
This applies to word in ${v-word}, ${v+word}, ${v=word}, ${v?word} (which
inherits quoting from the outside) and in ${v%word}, ${v%%word}, ${v#word},
${v##word} (which does not inherit any quoting).

In all cases tilde expansion is only attempted at the start of word, even if
word contains spaces. This agrees with POSIX and other shells.

8cf06f5eee sh: Fix various things about expansions:
* remove the backslash from \} inside double quotes inside +-=?

* maintain separate double-quote state for ${v#...} and ${v%...};
  single and double quotes are special inside, even in a double-quoted
  string or here document
* keep track of correct order of substitutions and arithmetic

This is different from dash's approach, which does not track individual
double quotes in the parser, trying to fix this up during expansion.
This treats single quotes inside "${v#...}" incorrectly, however.

This is similar to NetBSD's approach (as submitted in PR bin/57554), but
recognizes the difference between +-=? and #% substitutions hinted at in
POSIX and is more refined for arithmetic expansion and here documents.

Although simple commands without a command word (only assignments and/or

agree that redirection errors should not abort the shell in this case. Of
course, the assignments persist and assignment errors are fatal.

To get the old behaviour portably, use the ':' special builtin.
To get the new behaviour portably, given that there are no assignments, use
the 'true' regular builtin.

That is, do not do tilde expansion if any of the CTL* bytes (\201-\210), not
only CTLESC and CTLQUOTEMARK, are encountered. Such an expansion would look
up a user name with sh's internal representation.

The parser does not currently distinguish between backslashed and
unbackslashed \201-\210, so tilde expansion of user names with these bytes
in them is not so easy to fix.

e1ef314121 Fix some cases where file descriptors from redirections leak to programs.
- Redirecting fds that were not open before kept two copies of the
  redirected file.
    sh -c '{ :; } 7>/dev/null; fstat -p $$; true'
    (both fd 7 and 10 remained open)
- File descriptors used to restore things after redirection were not
  set close-on-exec, instead they were explicitly closed before executing
  a program normally and before executing a shell procedure. The latter
  must remain but the former is replaced by close-on-exec.
    sh -c 'exec 7</; { exec fstat -p $$; } 7>/dev/null; true'
    (fd 10 remained open)

The examples above are simpler than the testsuite because I do not want to
use fstat or procstat in the testsuite.

* exception handlers are now run with interrupts disabled, which avoids

* fix some cases where SIGINT only aborts one command and continues the
  script, in particular if a SIGINT causes an EINTR error which trumped the
  interrupt.

Example:
  sh -c 'echo < /some/fifo; echo This should not be printed'
The fifo should not have writers. When pressing ctrl+c to abort the open,
the shell used to continue with the next command.

Example:
  sh -c '/bin/echo < /some/fifo; echo This should not be printed'
Similar. Note, however, that this particular case did not and does not work
in interactive mode with job control enabled.

stuff after the syntax error and exited.

This should also avoid similar issues with 'command eval' and 'command .'

deda5987bc With NFSv4 ACLs, it is possible that applying a mode to an ACL which
is identical to the mode computed from that ACL will modify the ACL.
For example, mode computed from the following ACL is 0600:

   user:kamila:rwx--------C--:------:allow
        owner@:--x-----------:------:deny
        owner@:rw-p---A-W-Co-:------:allow
        group@:rwxp----------:------:deny
        group@:--------------:------:allow
     everyone@:rwxp---A-W-Co-:------:deny
     everyone@:------a-R-c--s:------:allow

However, applying that mode (chmod 0600) changes the ACL into this:

   user:kamila:rwx-----------:------:deny
   user:kamila:rwx--------C--:------:allow
        owner@:--x-----------:------:deny
        owner@:rw-p---A-W-Co-:------:allow
        group@:rwxp----------:------:deny
        group@:--------------:------:allow
     everyone@:rwxp---A-W-Co-:------:deny
     everyone@:------a-R-c--s:------:allow

In chmod(1) utility, there is an optimisation, which makes it not
call chmod(2) if the mode of the file is the same as the new mode.
Disable that optimisation for files which may have NFSv4 ACLs.

4f6e4215a0 Do not fork for a subshell if it is the last thing this shell is doing
(EV_EXIT). The fork is still done as normal if any traps are active.

In many cases, the fork can be avoided even without this change by using {}
instead of (), but in practice many scripts use (), likely because the
syntax is simpler.

Example:
  sh -c '(/bin/sleep 10)& sleep 1;ps -p $! -o comm='
Now prints "sleep" instead of "sh". $! is more useful this way.
Most shells (dash, bash, pdksh, ksh93, zsh) seem to print "sleep" for this.

3055b7c6ff Properly flush input after an error in backquotes in interactive mode.
For parsing an old-style backquote substitution (`...`),
a string "file" is used to store the contents of the
substitution (with the special backslash processing done).
If an error occurs, the shell cleans up all these files
(returning to the top level) and flush the top level
file. Erroneously, it first flushed the current file and
then cleaned up all extra files, so that the top level
file (i.e. the terminal) was not flushed.

Example (in interactive mode):
  echo `for` echo This should not be printed

Also noticeable in (in interactive mode):
  echo `(`
The old version prints an extraneous prompt.

960da93430 Avoid leaving unnecessary waiting shells in many forms of sh -c COMMAND.
This change only affects strings passed to -c, when the -s
option is not used.

The approach is to check if there may be additional data
in the string after parsing each command. If there is none,
use the EV_EXIT flag so that a fork may be omitted in
specific cases.

If there are empty lines after the command, the check will
not see the end and forks will not be omitted. The same
thing seems to happen in bash.

Example:
  sh -c 'ps lT'
No longer shows a shell process waiting for ps to finish.

00e8c94f25 Fix various cases with 3 or 4 parameters in test(1) to be POSIX compliant.
More precisely, this gives precedence to an interpretation not using the
'(', ')', '-a' and '-o' in their special meaning, if possible. For example,
it is now safe to write [ "$a" = "$b" ] and assume it compares the two
strings.

The man page already says that test(1) works this way, so does not need to
be changed.

Interpretation of input with more parameters tries a bit harder to find a
valid parse in some cases.

Add various additional test cases to TEST.sh.

ae46d95884 Don't disable CR-to-NL translation when waiting for data to arrive.
A difference between the old and the new TTY layer is that the new
implementation does not perform any post-processing before returning
data back to userspace when calling read().

sh(1)'s read turns the TTY into a raw mode before calling select(). This
means that the first character will not receive any ICRNL processing.
Inherit this flag from the original terminal attributes.

Even though this issue is not present on RELENG_*, I'm MFCing it to make
sh(1) in jails behave better.

rather than a voltag name, do not set the CESR_VOLTAGS flags in the
CHIOGSTATUS command requesting the current status.  As voltags are an
optional feature that must be handled as "reserved" by media changers

the command being aborted with an `Invalid field in CDB', and
consequently the "chio return" failed, for media changers that do not

Because we now enforce UNIX98-style PTY's, we now use a lot of TTY's

Initially, 'acl' (an 'acl_t *') is allocated, and its ACCESS_ACL and
DEFAULT_ACL fields are passed to the 'libc' ACL routines for subsequent
allocation. If the '-m' option (merge existing ACL with a new one) is
specified, then 'set_acl_mask()' will be called and passed one of the
two ACLs. This function, in turn, replaces this given ACL structure by
another, freshly allocated. However, the pointer in the 'acl' variable
in the caller is not updated. The caller then proceeds to free the ACL,
incurring in a double free condition.

bc093719ca Integrate the new MPSAFE TTY layer to the FreeBSD operating system.
The last half year I've been working on a replacement TTY layer for the
FreeBSD kernel. The new TTY layer was designed to improve the following:

- Improved driver model:

  The old TTY layer has a driver model that is not abstract enough to
  make it friendly to use. A good example is the output path, where the
  device drivers directly access the output buffers. This means that an
  in-kernel PPP implementation must always convert network buffers into
  TTY buffers.

  If a PPP implementation would be built on top of the new TTY layer
  (still needs a hooks layer, though), it would allow the PPP
  implementation to directly hand the data to the TTY driver.

- Improved hotplugging:

  With the old TTY layer, it isn't entirely safe to destroy TTY's from
  the system. This implementation has a two-step destructing design,
  where the driver first abandons the TTY. After all threads have left
  the TTY, the TTY layer calls a routine in the driver, which can be
  used to free resources (unit numbers, etc).

  The pts(4) driver also implements this feature, which means
  posix_openpt() will now return PTY's that are created on the fly.

- Improved performance:

  One of the major improvements is the per-TTY mutex, which is expected
  to improve scalability when compared to the old Giant locking.
  Another change is the unbuffered copying to userspace, which is both
  used on TTY device nodes and PTY masters.

Upgrading should be quite straightforward. Unlike previous versions,
existing kernel configuration files do not need to be changed, except
when they reference device drivers that are listed in UPDATING.

PWD, OLDPWD and the path used for the pwd builtin according to the new
directory.  For a logical directory change, chdir() is now called between
those two functions, no longer causing wrong values to be stored in PWD etc. if
it fails.

- Moving a directory to an existing non-empty directory will now fail,

- Improve consistency and remove some style bugs of earlier versions.

3a44a28835 When moving a directory across devices to a place where a directory
with the same name exists, delete that directory first, before performing
the copy.  This ensures that mv(1) across devices follows the semantics
of rename(2), as required by POSIX.

This change could introduce the potential of data loss, even if the
copy fails, violating the atomicity properties of rename(2).  This is
(mostly) mitigated by first renaming the destination and obliterating
it only after a succesfull copy.

The above logic also led to the introduction of code that will cleanup
the results of a partial copy, if a cross-device copy fails.

7ab24ea3b9 Introduce a way to make pure kernal threads.
kthread_add() takes the same parameters as the old kthread_create()
plus a pointer to a process structure, and adds a kernel thread
to that process.

kproc_kthread_add() takes the parameters for kthread_add,
plus a process name and a pointer to a pointer to a process instead of just
a pointer, and if the proc * is NULL, it creates the process to the
specifications required, before adding the thread to it.

All other old kthread_xxx() calls return, but act on (struct thread *)
instead of (struct proc *). One reason to change the name is so that
any old kernel modules that are lying around and expect kthread_create()
to make a process will not just accidentally link.

fix top to show  kernel threads by their thread name in -SH mode
add a tdnam formatting option to ps to show thread names.

make all idle threads actual kthreads and put them into their own idled process.
make all interrupt threads kthreads and put them in an interd process
(mainly for aesthetic and accounting reasons)
rename proc 0 to be 'kernel' and it's swapper thread is now 'swapper'

2966d28c32 Significantly reduce the memory leak as noted in BUGS section for
setenv(3) by tracking the size of the memory allocated instead of using
strlen() on the current value.

Convert all calls to POSIX from historic BSD API:
 - unsetenv returns an int.
 - putenv takes a char * instead of const char *.
 - putenv no longer makes a copy of the input string.
 - errno is set appropriately for POSIX.  Exceptions involve bad environ
   variable and internal initialization code.  These both set errno to
   EFAULT.

Several patches to base utilities to handle the POSIX changes from
Andrey Chernov's previous commit.  A few I re-wrote to use setenv()
instead of putenv().

New regression module for tools/regression/environ to test these
functions.  It also can be used to test the performance.

86da4a5eea Correct a security issue introduced in previous commit:
instead of removing the file and issue a warning about
the removal, do not do any operation at all in case -P
is specified when the dinode has hard links.

With -f and -P specified together, we assume that the
user wants rm to overwrite the contents of the file
and remove it (destroy the contents of file but leave
its hard links as is).

The reason of doing it this way is that, in case where
a hard link is created by a malicious user (currently
this is permitted even if the user has no access to the
file).  Losing the link can potentially mean that the
actual owner would lose control completely to the user
who wants to obtain access in a future day.

when we set the BLOCKSIZE environment variable, we use "1k" instead of "1024",
making the header display incorrectly.

To quote the specification:

"When both the -k and -P options are specified, the following header line
 shall be written (in the POSIX locale):

"Filesystem 1024-blocks Used Available Capacity Mounted on\n"

- If -P has been specified, check to make sure that -k has not already been
  specified, if so, simply break instead of clobbering the previous blocksize
- Use 1024 instead of 1k to make the header POSIX compliant

85170a4a2a Implement some of the differences between special built-ins and other builtins
demanded by POSIX.
- A redirection error is only fatal (meaning the execution of a shell script is
  terminated) for special built-ins.  Previously it was fatal for all shell
  builtins, causing problems like the one reported in PR 88845.
- Variable assignments remain in effect for special built-ins.
- Option or operand errors are only fatal for special built-ins.
This change also makes errors from 'fc' non-fatal (I could not find any reasons
for this behaviour).

Somewhat independently from the above down-grade the error handling in the
shift built-in if the operand is bigger than $# from an error() call (which is
now fatal) to a return 1.  I'm not sure if this should be considered a POSIX
"operand error", however this change is needed for now as we trigger that error
while building libncurses.  Comparing with other shells, zsh does the same as
our sh before this change (write a diagnostic, return 1), bash behaves as our
sh after this commit (no diagnostic, return 1) and ksh93 and NetBSD's sh treat
it as a fatal error.

all column-headers to print in lowercase by default.  I was in too
much of a rush in committing 1.75, and didn't notice that the case
had changed.  This time I did considerably more testing, and used
'diff' instead of just quickly eyeballing the results...

Apologies.  I expect this means the dunce cap is mine for awhile.
If this doesn't work, I'll just drop back to 1.72 and hide under

e5f1cf0838 Issue an error when . (dot) is invoked without a filename. The synopsis
is just ". file" according to POSIX, however many other shells allow
arguments to be passed after the file.  For compatibility (we even use that

error, even though this shell does not do anything with the arguments at all.

86cca1e75e Fix a bug such that if you enabled sorting by size (-S) and enabled a
flag to use a time other than modtime (-c, -u, or -U), the output would
actually be sorted by the specified time rather than size.  This does
alter the behavior in the case where both -S and -t are specified.  Now,
-S is always preferred.  Previously, -t was preferred if one of -c, -u, or
-U was specified, and -S was preferred otherwise.  Perhaps -S and -t should
override each other (last one specified wins).

f45c0422fc Enable NLS catalog of csh(1).
The tcsh 6.14 uses libiconv to convert catalogs to appropriate charset
dynamically.  However, we don't have libiconv in our tree.  So, I made
some hack to load libiconv dynamically.  If libiconv is available, you
can use catalogs for more locales than the locales which catalog is
actually installed.
To use this feature, you need to symlink catalogs to appropriate
locales.  You can do this by installing ports/shells/tcsh_nls.
