This works around brokenness in buildworld's bootstrapping logic: it
uses the source tree's metadata to collect dependency info (such as,
"libdwarf depends on libz") but links against static host libraries.
If these two are out of sync, as is the case if one builds a commit
prior to the introduction of the libz dependency, then the build fails
when trying to statically link nm(1).
Mitigate the problem by defining a weak uncompress() symbol which simply
returns an error. This ensures that the build won't fail when
statically linking libdwarf without zlib. The downside is that any
tools using libdwarf without zlib will now hit a runtime error if they
attempt to decode compressed sections, but at least they'll fail
deterministically, and compressed debug info is only enabled by default
in main.
In particular, this fixes building of branches lacking commit
dbf05458e3, such as releng branches, stable/12 and 13 and old
revisions of main. Previously the nm(1) build would fail with:
ld: error: undefined symbol: uncompress
>>> referenced by libdwarf_elf_init.c:233

[Mips] Add glue between CopyFromReg, CopyToReg and RDHWR nodes for TLS
The MIPS ABI requires the thread pointer be accessed via rdhwr $3, $r29.
This is currently represented by (CopyToReg $3, (RDHWR $29)) followed by
a (CopyFromReg $3). However, there is no glue between these, meaning
scheduling can break those apart. In particular, PR51691 is a report
where PseudoSELECT_I was moved to between the CopyToReg and CopyFromReg,
and since its expansion uses branches, it split the def and use of the
physical register between two basic blocks, resulting in the def being
eliminated and the use having no def. It also seems possible that a
similar situation could arise splitting up the CopyToReg from the RDHWR,
causing the RDHWR to use a destination register other than $3, violating
the ABI requirement.
Thus, add glue between all three nodes to ensure they aren't split up
during instruction selection. No regression test is added since any test
would be implictly relying on specific scheduling behaviour, so whilst
it might be testing that glue is preventing reordering today, changes to
scheduling behaviour could result in the test no longer being able to
catch a regression here, as the reordering might no longer happen for
other unrelated reasons.

Upstream one-true-awk has two sets of tests. These are in addition to
NetBSD's tests we're using. The 'bugs-fixed' tests from upstream are
ready to use as-is (more or less). However, the 'tests' from upstream
are not, so for now we'll just use the netbsd and bugs-fixed tests.
They provide an OK workout and are better than nothing, though the tests
themselves are for specific esoteric things.
The upstream bugs-fixed tests are *ALMOST* a drop in. However, 3 test
for errors and the upstream test jig mashes stdout and stderr together,
which atf doesn't do, so make a tiny tweak to the upstream tests that I
hope to upstream. Plus upstream has ../a.out: instead of awk: in the
output. Not sure how to deal with this yet, so I've not proposed
anything upstream and have changed the test locally.
In addition, the system-status.awk test is not suitable to run in ATF.
It wants to force sh to dump core, but kyua doesn't seem to allow that
sometimes so the test will fail or pass based on whether or not a core
dump can be created. Since it's unstable, remove it.
This required moving the netbsd tests to a new direcotry, so update
mtree files as well. The change is useless for 'make check' without it.

Cherry-picked from libfido2 upstream f20a735c0a6f:
iso7816: Avoid storing pointers in a packed structure
On CHERI, and thus Arm's experimental Morello prototype architecture,
pointers are represented as capabilities, which are unforgeable bounded
pointers, providing always-on fine-grained spatial memory safety. The
unforgeability is enforced through the use of tagged memory, with one
validity tag bit per capability-sized-and-aligned word in memory. This
means that storing a pointer to an unaligned location, which is not
guaranteed to work per the C standard, either traps or results in the
capability losing its tag (and thus never being dereferenceable again),
depending on how exactly the store is done (specifically, whether a
capability store or memcpy is used).
However, iso7816 itself does not need to be packed, and doing so likely
causes inefficiencies on existing architectures. The iso7816_header_t
member is packed, and the flexible payload array is a uint8_t (which by
definition has no padding bits and is exactly 8 bits in size and, since
CHAR_BITS must be at least 8, its existence implies that it has the same
representation as unsigned char, and that it has size and alignment 1)
so there will never be any padding inserted between header and payload
(but payload may overlap with padding at the end of the struct due to
how flexible arrays work, which means we need to be careful about our
calculations).

As reported by Ronald, adding the out-of-line LSE atomics helpers for

Upstream one-true-awk decided to disallow hex strings as numbers. This
is in line with awk's behavior prior to C99, and allowed by the POSIX
standard. The standard, however, allows them to be treated as numbers
because that's what the standard said in the 2001 through 2004 editions.
Since 2001, the nawk in FreeBSD has treated them as numbers, so restore
that behavior, allowed by the standard.
A number of scripts in the FreeBSD tree depend on this interpretation,
including scripts to build the kernel which had mysteriously started
failing for some people and not others. By re-allowing 0x hex numbers,
this fixes those scripts and restores POLA.

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").

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.

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
not doing anything.
Instead of incorrectly calling this API, use clnt_create_timed() instead.
I noticed this because the test was timing out after 120s in the CheriBSD CI.

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.

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.

This includes improvements to the atf-sh helper functions that
significantly reduce the number of spawned processes for each test
and therefore speeds up running the testsuite noticeably.
OpenSSL BIO classes provide an abstraction for dealing with I/O.
OpenSSL provides BIO classes for commonly used I/O primitives backed
by file descriptors, sockets, etc. as well as permitting consumers
of OpenSSL to define custom BIO classes.
One of the methods BIO classes implement is a control method invoked
by BIO_ctrl() for various ancilliary tasks somewhat analgous to
fcntl() and ioctl() on file descriptors. According to the BIO_ctrl(3)
manual page, control methods should return 0 for unknown control
requests.
KTLS support in OpenSSL adds new control requests. Two of those new
requests are queries to determine if KTLS is enabled for either
reading or writing. These control reuquest return 1 if KTLS is
enabled and 0 if it is not.
serf includes two custom BIO classes for wrapping I/O requests from
files and from a buffer in memory. These BIO classes both use a
custom control method. However, this custom control method was
returning 1 for unknown or unsupported control requests instead of 0.
As a result, OpenSSL with KTLS believed that these BIOs were using
KTLS and were thus adding headers and doing encryption/decryption in
the BIO. Correcting the return value removes this confusion.

Merge commit 740a164de from llvm git (by Richard Smith):
PR46377: Fix dependence calculation for function types and typedef
types.
We previously did not treat a function type as dependent if it had a
parameter pack with a non-dependent type -- such a function type depends
on the arity of the pack so is dependent even though none of the
parameter types is dependent. In order to properly handle this, we now
treat pack expansion types as always being dependent types (depending on
at least the pack arity), and always canonically being pack expansion
types, even in the unusual case when the pattern is not a dependent
type. This does mean that we can have canonical types that are pack
expansions that contain no unexpanded packs, which is unfortunate but
not inaccurate.
We also previously did not treat a typedef type as
instantiation-dependent if its canonical type was not
instantiation-dependent. That's wrong because instantiation-dependence
is a property of the type sugar, not of the type; an
instantiation-dependent type can have a non-instantiation-dependent
canonical type.

determine the length of the routing table buffer. As of 81728a538d
wpa_supplicant is started before the routing table has been populated

If any PHI nodes in loop exit blocks have incoming values from the

Since this includes a call to __tls_get_addr, this will in turn cause

This reverts commit 89e3d5671b.
As pointed out, there are several problems with that commit:
1. The new semantics, while useful for clients where multiple
threads use separate contexts, breaks clients which correctly
share a single one
2. Change in semantics would require a library version bump
3. It doesn't build with GCC
Fix error in extent_try_coalesce_impl(), which could cause abort
to happen when trying to coalesce extents backwards. The error could
happen because of how extent_before_get() function works. This function
gets address of previous extent, by subtracting page size from current
extent address. If current extent is located at PAGE_SIZE offset, this
address resolved to 0x0000. An assertion in rtree_leaf_elm_lookup
then caused the running program to abort.
This problem was discovered when trying to build world on 32-bit
machines with ASLR and PIE enabled. The problem was encountered
on armv7 and i386 machines, but most likely other 32-bit
architectures are affected as well.
While this patch fixes one problem with buildworld on 32-bit platforms
with ASLR, the build still fails, however it happens much later
and due to lack of memory.
The change is aligned with accepted fix in the upstream Jemalloc
repository (https://github.com/jemalloc/jemalloc/pull/1973).
As it doesn't apply on top of Jemalloc tree, its updated version
was eventually merged: https://github.com/jemalloc/jemalloc/pull/2003
