libarchive: Apply upstream commit a1b7bf8013fb7a11a486794247daae592db6f5ae
This fixes the failing test_read_append_filter_wrong_program test in CI
which has been failing since 01-Dec-2020.
Commit message from a1b7bf8013
Silence stderr in test_read_append_filter_program
When the FreeBSD testsuite runs the libarchive tests it checks that stderr
is empty. Since #1382 this is no longer the case. This change restores
the behaviour of silencing bunzip2 stderr but doesn't bring back the
output text check.

Update to version 4.0.0
This version fixes an issue (missing pop of top-of-stack value in the
"P" command of the dc program).
This issue did not affect the bc program, since it does not use dc as
an back-end to actually perform the calculations as was the case with
the traditional bc and dc programs.
The major number has been bumped due to Windows support that has been
added to this version. It does not correspond to a major change that
might affect FreeBSD.
GNU readelf exits with an error for a number of invalid file cases.
Previously ELF Tool Chain readelf always exited with 0. Now we exit 1
upon detecting an error with one or more input files, but in any case
all of them are processed.
This should catch common failure cases. We still do not report an error
for some types of malformed ELF files, but this is consistent with GNU
readelf.

3a509754de removed the color field from our definition, but libevent1
has a copy of it off to the side to prevent event.h consumers from
*needing* to pull in sys/queue.h and sys/tree.h.
Update the event.h definition so that we don't accidentally end up with
two different views of struct event.

Currently macOS and DragonFlyBSD get their own special case and only
handle x86. Since all the FreeBSD cases should be general enough for
macOS and DragonFlyBSD (and the x86 ones are identical to the existing
ones) we can just delete the special cases and reuse the FreeBSD ones.
Note that upstream has since removed all the architecture-specific
checks in this file, with the only code relevant to us being an
endianness check that uses the generic compiler-provided macros. Thus
this patch will not be upstreamed, and will be dropped in a future
vendor import.

Merge commit '893ecb52db5ed47d6c1e8698334d34e0df651612'
Latest version available from: https://w1.fi/security/2021-1/
Vulnerability
A vulnerability was discovered in how wpa_supplicant processes P2P
(Wi-Fi Direct) provision discovery requests. Under a corner case
condition, an invalid Provision Discovery Request frame could end up
reaching a state where the oldest peer entry needs to be removed. With
a suitably constructed invalid frame, this could result in use
(read+write) of freed memory. This can result in an attacker within
radio range of the device running P2P discovery being able to cause
unexpected behavior, including termination of the wpa_supplicant process
and potentially code execution.
Vulnerable versions/configurations
wpa_supplicant v1.0-v2.9 with CONFIG_P2P build option enabled
An attacker (or a system controlled by the attacker) needs to be within
radio range of the vulnerable system to send a set of suitably
constructed management frames that trigger the corner case to be reached
in the management of the P2P peer table.
Note: FreeBSD base does not enable P2P.
(Note I am also applying this to main and stable/13, to restore the old
libcxxrt ABI and to avoid having to maintain a compat library.)
After the recent cherry-picking of libcxxrt commits 0ee0dbfb0d and
d2b3fadf2d, users reported that editors/libreoffice packages from the
official package builders did not start anymore. It turns out that the
combination of these commits subtly changes the ABI, requiring all
applications that depend on internal details of struct _Unwind_Exception
(available via unwind-arm.h and unwind-itanium.h) to be recompiled.
However, the FreeBSD package builders always use -RELEASE jails, so
these still use the old declaration of struct _Unwind_Exception, which
is not entirely compatible. In particular, LibreOffice uses this struct
in its internal "uno bridge" component, where it attempts to setup its
own exception handling mechanism.
To fix this incompatibility, go back to the old declarations of struct
_Unwind_Exception, and restore the __LP64__ specific workaround we had
in place before (which was to cope with yet another, older ABI bug).
Effectively, this reverts upstream libcxxrt commits 88bdf6b290da
("Specify double-word alignment for ARM unwind") and b96169641f79
("Updated Itanium unwind"), and reapplies our commit 3c4fd2463b
("libcxxrt: add padding in __cxa_allocate_* to fix alignment").

Update the tests to check O_RESOLVE_BENEATH instead.
If this looks reasonable, I'll try to upstream this change.
This keeps a compat fallback for O_BENEATH since the Linux port still
has/had O_BENEATH with "no .., no absolute paths" semantics.
Test Plan: `/usr/tests/sys/capsicum/capsicum-test -u 977` passes and
runs the O_RESOLVE_BENEATH tests.

Clang commit ccb4124a4172bf2cb2e1cd7c253f0f1654fce294:
Fix -gz=zlib options for linker
gcc translates -gz=zlib to --compress-debug-options=zlib for both
assembler and linker but clang only does this for assembler.
The linker needs --compress-debug-options=zlib option to compress the
debug sections in the generated executable or shared library.
Due to this bug, -gz=zlib has no effect on the generated executable or
shared library.
This patch fixes that.

Submitted upstream as https://github.com/google/capsicum-test/pull/56
Reported by: Jenkins CI
This includes various fixes that I submitted recently such as updating the
pdkill() tests for the actual implemented behaviour
(https://github.com/google/capsicum-test/pull/53) and lots of changes to
avoid calling sleep() and replacing it with reliable synchronization
(pull requests 49,51,52,53,54). This should make the testsuite more reliable
when running on Jenkins. Additionally, process status is now retrieved using
libprocstat instead of running `ps` and parsing the output
(https://github.com/google/capsicum-test/pull/50). This fixes one previously
failing test and speeds up execution.
Overall, this update reduces the total runtime from ~60s to about 4-5 seconds.
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.

After 0ee0dbfb0d where I imported a more
recent libcxxrt snapshot, the variables 'rtn' and 'has_ret' could in
some cases be used while still uninitialized. Most obviously this would
lead to a jemalloc complaint about a bad free(), aborting the program.
Fix this by initializing a bunch variables in their declarations. This
change has also been sent upstream, with some additional changes to be

Since having both fixes makes the struct too large again, it leads to
SIGBUSes when throwing exceptions on amd64 (or other LP64 arches). This
is most easily tested by running kyua without any arguments.

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.

This update changes the behavior of "-e" or "-f" in BC_ENV_ARGS:
Use of these options on the command line makes bc exit after executing
the given commands. These options will not cause bc to exit when
passed via the environment (but EOF in STDIN or -e or -f on the
command line will make bc exit as before).
The same applies to DC_ENV_ARGS with regard to the dc program.
Importing flex 2.6.4 has introduced a regression: input() now returns 0
instead of EOF to indicate that the end of input was reached, just like
traditional AT&T and POSIX lex. Note the behavior contradicts flex(1).
See "INCOMPATIBILITIES WITH LEX AND POSIX" section for information.
This incompatibility traces back to the original version and documented
in its manual page by the Vern Paxson.
Apparently, it has been reported in a few places, e.g.,
https://github.com/westes/flex/issues/448https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=911415
Unfortunately, this also breaks the scanner used by libdtrace and
dtrace is unable to resolve some probe argument types as a result. See
PR253440 for more information.
Note the regression was introduced by the following upstream commit
without any explanation or documentation change:
f863c9490e
Now we restore the traditional flex behavior unless lex-compatibility
mode is set with "-l" option because I believe the author originally
wanted to make it more lex and POSIX compatible.

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.
