Builtins (including variable assignments without command word), function
calls and redirected compound commands need to restore file descriptors
to their original state after execution. This is handled by allocating a
redirtab structure. These mallocs and frees show up heavily in pmcstat.
Only allocate a redirtab if there are actually redirections and maintain a
count of how many levels of REDIR_PUSH there are without redirtabs.
A simple loop without external programs like
sh -c 'i=0; w=$(printf %0100d 7); while [ "$i" -lt 1000000 ]; do
i=$((i+1)); done'
is over 25% faster on an amd64 bhyve VM.
The linear search using strcmp() shows up in pmcstat for several percent.
Split the operators into lengths and whether they start with '-' and compare
bytes using == instead of strcmp().
A simple test
sh -c 'i=0; w=$(printf %0100d 7); while [ "$i" -lt 1000000 ]; do
v=$(printf %sx%s "$w" "$w"); i=$((i+1)); done'
is over 4% faster on an amd64 bhyve VM.
Forbid (temporary or permanent) modifications of the strings in NARG nodes
during expansion.
Tilde expansion now needs to copy the username for the terminating '\0'.
Per POSIX, 'cd -' should use the OLDPWD shell variable, not internal state.
This variable is normally exported.
Also, if OLDPWD is not set, fail 'cd -' instead of changing to the current
directory.
Some variables like PATH call a function when modified. Make sure to call
this also when leaving a function where such a variable was made local.
Make sure to restore local variables before shellparam, so getopts state is
not clobbered.
Redirect 'cd -' output to /dev/null since POSIX requires it to write the new
directory name even if not interactive, but we currently only write it if
interactive.
Command substitutions containing a single simple command and here-document
expansion are performed in a subshell environment, but may not fork. Any
modified state of the shell environment should be restored afterward.
The state that OPTIND=1 had been done was not saved and restored here.
Note that the other parts of shellparam need not be saved and restored,
since they are not modified in these situations (a fork is done before such
modifications).
With the new expand.c code, the intermediate representation passed to the
pathname generation code only contains CTLESC, not CTLQUOTEMARK.
CTLQUOTEMARK now only occurs in the text of NARG nodes (output of the
parser).
This avoids the need to add and remove CTLESC bytes if pathname generation
will not be performed (set -f).
Side effect: the order of operations is slightly different: pathname
generation in ${$+* $(CMD)} will not see filesystem changes from CMD.
This simplifies the code and should be faster in some cases.
Side effect: the order of operations is different so that the value of IFS
used when IFS is modified during expansion (${IFS:=...}, ${IFS=...} or
$((...IFS=...))) may be different. Note that this order is highly unportable
between shells.

Shell syntax is too complicated to detect command substitution and unquoted
operators reliably without implementing much of sh's parser. Therefore, have
sh do this detection.
While changing sh's support anyway, also read input from a pipe instead of
arguments to avoid {ARG_MAX} limits and improve privacy, and output count
and length using 16 instead of 8 digits.
The basic concept is:
execl("/bin/sh", "sh", "-c", "freebsd_wordexp ${1:+\"$1\"} -f "$2",
"", flags & WRDE_NOCMD ? "-p" : "", <pipe with words>);
The WRDE_BADCHAR error is still implemented in libc. POSIX requires us to
fail strings containing unquoted braces with code WRDE_BADCHAR. Since this
is normally not a syntax error in sh, there is still a need for checking
code in libc, we_check().
The new we_check() is an optimistic check that all the characters
<newline> | & ; < > ( ) { }
are quoted. To avoid duplicating too much sh logic, such characters are
permitted when quoting characters are seen, even if the quoting characters
may themselves be quoted. This code reports all WRDE_BADCHAR errors; bad
characters that get past it and are a syntax error in sh return WRDE_SYNTAX.
Although many implementations of WRDE_NOCMD erroneously allow some command
substitutions (and ours even documented this), there appears to be code that
relies on its security (codesearch.debian.net shows quite a few uses).
Passing untrusted data to wordexp() still exposes a denial of service
possibility and a fairly large attack surface.

3. Some of the NO_PIE use is a bit absurd as it is disabling PIE (and ASLR)

there may be better ways of adding support to the tree. Many of these

We likely do want to enable PIE by default (opt-out) for non-tree consumers
(such as ports). For in-tree though we probably want to only enable PIE
(opt-in) for common attack targets such as remote service daemons and setuid

Add the function proc_realparent(9), which calculates the parent for

to find the parent process. If the parent has already exited, the

Move the P_ORPHAN and the new helper flag from the p_flag* to new

On 64-bit systems, our atoi() takes the low 32 bits of the strtol() and

On 32-bit systems, the call to atoi() returned INT_MAX for too high values

there was no issue.
Although it is probably unwise to use this, POSIX is clear that leading

fflag to ignore fts_read errors, but stop deleting from that directory
because no further progress can be made.
When building a kernel with a high -j value on a high core count
machine, during the cleanobj phase we can wind up doing multiple rm
-rf at the same time for modules that have subdirectories. This
exposed this race (sometimes) as fts_read can return an error if the
directory is removed by another rm -rf. Since the intent of the -f
flag was to ignore errors, even if this was a bug in fts_read, we
should ignore the error like we've been instructed to do.
This is currently an opt-in build flag. Once ASLR support is ready and stable
it should changed to opt-out and be enabled by default along with ASLR.
Each application Makefile uses opt-out to ensure that ASLR will be enabled by
default in new directories when the system is compiled with PIE/ASLR. [2]

remove the now-redundant checks for RELEASE_CRUNCH. This originally
was defined for building smaller sysinstall images, but was later also
used by picobsd builds for a similar purpose. Now that we've moved
away from sysinstall, picobsd is the only remaining consumer of this
interface. Adding these two options reduces the RELEASE_CRUNCH
special cases in the tree by half.
When getopts finds an invalid option or a missing option-argument, it should
not reset its state and should set OPTIND as normal. This is an old ash bug
that was fixed long ago in dash. Our behaviour now matches most other
shells.
