c88c1f23a8 Allow ssp_test:read to pass more reliably
It appears that the stackframe layout can be slightly different depending on
compiler and target architecture. For example, when using CHERI LLVM for RISC-V
we can actually overflow the buffer by up to 8 bytes without SSP detecting it.
Fix this by increasing the overflow to 15 bytes.

2aa3ef285a libc: Fix t_spawn_fileactions test after ATF update
Since 4581cefc1e
ATF opens the results file on startup. This fixes problems like
capsicumized tests not being able to open the file on exit.

However, this test closes all file descriptors above 3 to get a
deterministic fd table allocation for the child. Instead of using closefrom
(which will close the ATF output file FD) I've changed this test use
the lowest available fd and pass that to the helper program as a string.

We could also try to re-open the results file in ATF if we get a EBADF
error, but that will fail when running under Capsicum.

10fc4c3218 Fix two failing tests after ATF update
Since 4581cefc1e
ATF opens the results file on startup. This fixes problems like
capsicumized tests not being able to open the file on exit.

However, this test closes all file descriptors just to check that
socketpair returns fd 3+4 and thereby also closes the ATF results file.
This then results in an EBADF when writing the result so the test is
reported as broken.

While system calls that create new file descriptors (must?) use the lowest
available file descriptor number, it does not seem useful to test this
property here. Drop the check for FD==3/4 to unbreak the testsuite.

We could also try to re-open the results file in ATF if we get a EBADF
error, but that will fail when running under Capsicum.

90b5fc9583 lib/libc/tests/rpc: Correctly set timeout
The rpc_control() API does not accept the CLCR_SET_RPCB_TIMEOUT command,
it only accepts RPC_SVC_CONNMAXREC_GET/RPC_SVC_CONNMAXREC_SET, so it was

3e2d96ac97 grep: fix -A handling in conjunction with -m match limitation
The basic issue here is that grep, when given -m 1, would stop all
line processing once it hit the match count and exit immediately.  The
problem with exiting immediately is that -A processing only happens when
subsequent lines are processed and do not match.

The fix here is relatively easy; when bsdgrep matches a line, it resets
the 'tail' of the matching context to the value supplied to -A and
dumps anything that's been queued up for -B. After the current line has
been printed and tail is reset, we check our mcount and do what's
needed. Therefore, at the time that we decide we're doing nothing, we
know that 'tail' of the context is correct and we can simply continue
on if there's still more to pick up.

With this change, we still bail out immediately if there's been no -A
flag. If -A was supplied, we signal that we should continue on. However,
subsequent lines will not even bothere to try and process the line.  We
have reached the match count, so even if the next line would match then
we must process it if it hadn't. Thus, the loop in procfile() can
short-circuit and just process the line as a non-match until
procmatches() indicates that it's safe to stop.

A test has been added to reflect both that we should be picking up the
next line and that the next line should be considered a non-match even
if it should have been.

f823c6dc73 grep: fix null pattern and empty pattern file behavior
The null pattern semantics were terrible because I tried to match gnugrep,
but I got it wrong.  Let's unwind that:

- The null pattern should match every line if neither -w nor -x.
- The null pattern should match empty lines if -x.
- The null pattern should not match any lines if -w.

The first two will stop processing (shortcut) even if additional patterns
are specified. In any other case, we will continue processing other
patterns.  If no other patterns are specified beside a null pattern, then
we match if neither -w nor -x or set and do not match if either of those
are specified.

The justification for -w is that it should match on a whole word, but the
null pattern deos not have a whole word to match on.

Empty pattern files should never match anything, and more importantly, -v
should cause everything to be written.

371f152c7f Significantly speed up libthr/mutex_test and make more reliable
Instead of using a simple global++ as the data race, with this change we
perform the increment by loading the global, delaying for a bit and then
storing back the incremented value. If I move the increment outside of the
mutex protected range, I can now see the data race with only 100 iterations
on amd64 in almost all cases. Before this change such a racy test almost
always passed with < 100,000 iterations and only reliably failed with the
current limit of 10 million.

I noticed this poorly written test because the mutex:mutex{2,3} and
timedmutex:mutex{2,3} tests were always timing out on our CheriBSD Jenkins.
Writing good concurrency tests is hard so I won't attempt to do so, but this
change should make the test more likely to fail if pthread_mutex_lock is not
implemented correctly while also significantly reducing the time it takes to
run these four tests. It will also reduce the time it takes for QEMU RISC-V
testsuite runs by almost 40 minutes (out of currently 7 hours).

adeebf4cd4 regex(3): Interpret many escaped ordinary characters as EESCAPE
In IEEE 1003.1-2008 [1] and earlier revisions, BRE/ERE grammar allows for
any character to be escaped, but "ORD_CHAR preceded by an unescaped
<backslash> character [gives undefined results]".

Historically, we've interpreted an escaped ordinary character as the
ordinary character itself. This becomes problematic when some extensions
give special meanings to an otherwise ordinary character
(e.g. GNU's \b, \s, \w), meaning we may have two different valid
interpretations of the same sequence.

To make this easier to deal with and given that the standard calls this
undefined, we should throw an error (EESCAPE) if we run into this scenario
to ease transition into a state where some escaped ordinaries are blessed
with a special meaning -- it will either error out or have extended
behavior, rather than have two entirely different versions of undefined
behavior that leave the consumer of regex(3) guessing as to what behavior
will be used or leaving them with false impressions.

This change bumps the symbol version of regcomp to FBSD_1.6 and provides the
old escape semantics for legacy applications, just in case one has an older
application that would immediately turn into a pumpkin because of an
extraneous escape that's embedded or otherwise critical to its operation.

This is the final piece needed before enhancing libregex with GNU extensions
and flipping the switch on bsdgrep.

c4cbf1fbab Fix some regressions with the zgrep(1) wrapper.
- Handle whitespace with long flags that take arguments:

	echo 'foo bar' > test
	zgrep --regexp='foo bar' test

 - Do not hang reading from stdin with patterns in a file:

	echo foobar > test
	echo foo > pattern
	zgrep -f pattern test
	zgrep --file=pattern test

 - Handle any flags after -e:

	echo foobar > test
	zgrep -e foo --ignore-case < test

These two are still outstanding problems:

 - Does not handle flags that take an argument if there is no
   whitespace:

	zgrep -enfs /etc/rpc

 - When more than one -e pattern used matching should occur for all
   patterns (similar to multiple patterns supplied with -f file).
   Instead only the last pattern is used for matching:

	zgrep -e rex -e nfs /etc/rpc

   (This problem is masked in the unpatched version by the "any
   flags after -e" problem.)

Add tests for the above problems.

Update the mange and add references to gzip(1) and zstd(1) and also
document the remaining known problems.

14d3b06919 O_SEARCH test: mark revokex an expected fail on NFS
The revokex test does not work when the scratch directory is created on NFS.
Given the nature of NFS, it likely can never work without looking like a
security hole since O_SEARCH would rely on the server knowing that the
directory did have +x at the time of open and that it's OK for it to have
been revoked based on POSIX specification for O_SEARCH.

This does mean that O_SEARCH is only partially functional on NFS in general,
but I suspect the execute bit getting revoked in the process is likely not
common.

6a5abb1ee5 Provide O_SEARCH
O_SEARCH is defined by POSIX [0] to open a directory for searching, skipping
permissions checks on the directory itself after the initial open(). This is
close to the semantics we've historically applied for O_EXEC on a directory,
which is UB according to POSIX. Conveniently, O_SEARCH on a file is also
explicitly undefined behavior according to POSIX, so O_EXEC would be a fine
choice. The spec goes on to state that O_SEARCH and O_EXEC need not be
distinct values, but they're not defined to be the same value.

This was pointed out as an incompatibility with other systems that had made
its way into libarchive, which had assumed that O_EXEC was an alias for
O_SEARCH.

This defines compatibility O_SEARCH/FSEARCH (equivalent to O_EXEC and FEXEC
respectively) and expands our UB for O_EXEC on a directory. O_EXEC on a
directory is checked in vn_open_vnode already, so for completeness we add a
NOEXECCHECK when O_SEARCH has been specified on the top-level fd and do not
re-check that when descending in namei.

38325e2ab8 bsdgrep(1): various fixes of empty pattern/exit code/-c behavior
When an empty pattern is encountered in the pattern list, I had previously
broken bsdgrep to count that as a "match all" and ignore any other patterns
in the list. This commit rectifies that mistake, among others:

- The -v flag semantics were not quite right; lines matched should have been
  counted differently based on whether the -v flag was set or not. procline
  now definitively returns whether it's matched or not, and interpreting
  that result has been kicked up a level.
- Empty patterns with the -x flag was broken similarly to empty patterns
  with the -w flag. The former is a whole-line match and should be more
  strict, only matching blank lines. No -x and no -w will will match the
  empty string at the beginning of each line.
- The exit code with -L was broken, w.r.t. modern grep. Modern grap will
  exit(0) if any file that didn't match was output, so our interpretation
  was simply backwards. The new interpretation makes sense to me.

Tests updated and added to try and catch some of this.

This misbehavior was found by autoconf while fixing ports found in PR 229925
expecting either a more sane or a more GNU-like sed.
