Some points for the future:
- libc is not the right place for sorting algorithms.
Probably libutil is better suited for this purpose or
a dedicated libsort. Should move all sorting algorithms
away from libc eventually.
- CheriBSD uses capabilities for memory access, and could
benefit from a standard memswap() function.
- Do something about qsort() in FreeBSD's libc like:
- Mark it deprecated on FreeBSD, as a first step,
due to missing limits on CPU time.
- Audit the use of qsort() in the FreeBSD base system
and consider swapping to other existing sorting
algorithms.

This reverts commit 7d65a450cd.
This reverts commit 8dcf3a82c5.
The bsort(3) algorithm works by swapping objects, similarly to qsort(3),
and does not require any significant amount of additional memory.
The bsort(3) algorithm doesn't suffer from the processing time issues
known the plague the qsort(3) family of algorithms, and is bounded by
a complexity of O(log2(N) * log2(N) * N), where N is the number of
elements in the sorting array. The additional complexity compared to
mergesort(3) is a fair tradeoff in situations where no memory may
be allocated.
The bsort(3) APIs are identical to those of qsort(3), allowing for
easy drop-in and testing.
The design of the bsort(3) algorithm allows for future parallell CPU
execution when sorting arrays. The current version of the bsort(3)
algorithm is single threaded. This is possible because fixed areas
of the sorting data is compared at a time, and can easily be divided
among different CPU's to sort large arrays faster.

Add endian.h. This includes sys/endian.h and then adds extra defines

Move common parts of endian.h and sys/endian.h into sys/_endian.h

All this gives us good compatibility with Linux. There may be one or two
upstreams that haven't integrated the patches I tried to send up.
There are some minor differences:
o The extra glibc macros are not defined. These are all
controlled with either __ at the start, or only defined
when glibc is being built. We also don't define macros
that are used internally in glibc that would pollute

o For complete compatibility, this change must also be

The includes build is kind of funky, as we support either copying or
symlinking files into /usr/include. For `copies`, we were supplying
the include/ ${TAG_ARGS}, which puts packages into `FreeBSD-runtime`,
without any consideration to the fact that we're installing headers.
Let's copy the approach that the `symlinks` target uses for now, and
add ",dev" to the TAG_ARGS so that headers at least end up in
FreeBSD-runtime-dev, which is more appropriate. Some of these includes
are actually technically supposed to be in *other* packages and their
INCSGROUP's PACKAGE setting is actually correct, but this is less
trivial to solve. This is a bandaid to fix the immediate problem of

glibc-based interface.
Unfortunately, the glibc maintainers, despite knowing the existence
of the FreeBSD qsort_r(3) interface in 2004 and refused to add the
same interface to glibc based on grounds of the lack of standardization
and portability concerns, has decided it was a good idea to introduce
their own qsort_r(3) interface in 2007 as a GNU extension with a
slightly different and incompatible interface.
With the adoption of their interface as POSIX standard, let's switch
to the same prototype, there is no need to remain incompatible.
C++ and C applications written for the historical FreeBSD interface
get source level compatibility when building in C++ mode, or when
building with a C compiler with C11 generics support, provided that
the caller passes a fifth parameter of qsort_r() that exactly matches
the historical FreeBSD comparator function pointer type and does not
redefine the historical qsort_r(3) prototype in their source code.

The gunion(8) utility is used to track changes to a read-only disk on
a writable disk. Logically, a writable disk is placed over a read-only
disk. Write requests are intercepted and stored on the writable
disk. Read requests are first checked to see if they have been
written on the top (writable disk) and if found are returned. If
they have not been written on the top disk, then they are read from
the lower disk.
The gunion(8) utility can be especially useful if you have a large
disk with a corrupted filesystem that you are unsure of how to
repair. You can use gunion(8) to place another disk over the corrupted
disk and then attempt to repair the filesystem. If the repair fails,
you can revert all the changes in the upper disk and be back to the
unchanged state of the lower disk thus allowing you to try another
approach to repairing it. If the repair is successful you can commit
all the writes recorded on the top disk to the lower disk.
Another use of the gunion(8) utility is to try out upgrades to your
system. Place the upper disk over the disk holding your filesystem
that is to be upgraded and then run the upgrade on it. If it works,
commit it; if it fails, revert the upgrade.

Add two underscore characters "__" to names of BIT_* and BITSET_*
macros to move them to the implementation name space and to prevent
a name space pollution due to BIT_* macros in 3rd party programs with
conflicting parameter signatures.
These prefixed macro names are used in kernel header files to define
macros in e.g. sched.h, sys/cpuset.h and sys/domainset.h.
If C programs are built with either -D_KERNEL (automatically passed
when building a kernel or kernel modules) or -D_WANT_FREENBSD_BITSET
(or this macros is defined in the source code before including the
bitset macros), then all macros are made visible with their previous
names, too. E.g., both __BIT_SET() and BIT_SET() are visible with
either of _KERNEL or _WANT_FREEBSD_BITSET defined.
The main reason for this change is that some 3rd party sources
including sched.h have been found to contain conflicting BIT_*
macros.
As a work-around, parts of shed.h have been made conditional and
depend on _WITH_CPU_SET_T being set when sched.h is included.
Ports that expect the full functionality provided by sched.h need
to be built with -D_WITH_CPU_SET_T. But this leads to conflicts if
BIT_* macros are defined in that program, too.
This patch set makes all of sched.h visible again without this
parameter being passed and without any name space pollution due
to BIT_* macros becoming visible when sched.h is included.
This patch set will be backported to the STABLE branches, but ports
will need to use -D_WITH_CPU_SET_T as long as there are supported
releases that do not contain these patches.

Many of these typedefs are the same across all architectures or can

(e.g. __SIZEOF_SIZE_T__). These macros have been available since GCC 4.6
and Clang sometime before 3.0 (godbolt.org does not have any older clang
versions installed).
I originally considered using the compiler-provided `__FOO_TYPE__` directly.
However, in order to do so we have to check that those match the previous
typedef exactly (not just that they have the same size) since any change
would be an ABI break. For example, changing `long` to `long long` results
in different C++ name mangling. Additionally, Clang and GCC disagree on
the underlying type for some of (u)int*_fast_t types, so this change
only moves the definitions that are identical across all architectures
and does not touch those types.
This de-deduplication will allow us to have a smaller diff downstream in

- Jason A. Donenfeld <Jason@zx2c4.com>
- Matt Dunwoodie <ncon@noconroy.net>
- Kyle Evans <kevans@FreeBSD.org>
Notable changes include:
- Packets are now correctly staged for processing once the handshake has

- Various race conditions have been resolved, particularly w.r.t. socket

- Various tests have been added to assure correct functionality and
tooling conformance
- Many security issues have been addressed
- if_wg now maintains jail-friendly semantics: sockets are created in
the interface's home vnet so that it can act as the sole network
connection for a jail
- if_wg no longer fails to remove peer allowed-ips of 0.0.0.0/0
- if_wg now exports via ioctl a format that is future proof and
complete. It is additionally supported by the upstream
wireguard-tools (which we plan to merge in to base soon)
- if_wg now conforms to the WireGuard protocol and is more closely
aligned with security auditing guidelines
Note that the driver has been rebased away from using iflib. iflib
poses a number of challenges for a cloned device trying to operate in a
vnet that are non-trivial to solve and adds complexity to the
implementation for little gain.

It will be used by the upcoming HID-over-i2C implementation. Should be
no-op, except hid.ko module dependency is to be added to affected drivers.

Using a shell for loop means we have to spawn a separate install(1)
process for each header that is symlinked. This patch uses printf(1) to
generate an argument list that has been prefixed with the correct number
of ../ and then uses a single install(1) invocation.
This reduces the number of execve() calls during make includes from 2442
(with D27622) to 1382. Running `make symlinks` in include/ now spawns 214
processes instead of 1276 without this patch.

Instead of using install directly use INCSGROUPS for them.
All those files are the ones we installed when the directory have more .h
files that we don't want to install so they aren't using the LSUBDIR stuff.

These functions get/set tty winsize respectively, and are trivial wrappers
around corresponding termio ioctls.
The functions are expected to be a part of POSIX.1 issue 8:
https://www.austingroupbugs.net/view.php?id=1151#c3856.
They are currently available in NetBSD and in musl libc.

Provide a way to ask for an opaque version string for a locale_t, so
that potential changes in sort order can be detected. Similar to
ICU's ucol_getVersion() and Windows' GetNLSVersionEx(), this API is
intended to allow databases to detect when text order-based indexes
might need to be rebuilt.
The CLDR version is extracted from CLDR source data by the Makefile
under tools/tools/locale, written into the machine-generated Makefile
under shared/colldef, passed to localedef -V, and then written into
LC_COLLATE file headers. The initial version is 34.0.
tools/tools/locale was recently updated to pull down 35.0, but the
output hasn't been committed under share/colldef yet, so that will
provide the first observable change when it happens. Other versioning
schemes are possible in future, because the format is unspecified.

We no longer support old versions of GCC. Remove this check by
assuming it's false. That will make the entire expression false. Also
remove support for Intel compiler, it's badly bitrotted. Technically,
this removes support for C89 and K&R from compilers that don't define
_Bool in those compilation environments as well. I'm unaware of any
working compiler today for which that would be relevant (pcc has it
and tcc sadly isn't working for other reasons), though if one
pops up in ports, I'll work to resolve the issue.
Calendar files in LOCALBASE override similarily named ones in the base
system. This could easily be changed if the base system calendars should
have precedence, but it could lead to a violation of POLA since then the
port's files were ignored unless those in base have been deleted.
There was no definition of _PATH_LOCALBASE in paths.h, but verbatim uses
of /usr/local existed for _PATH_DEFPATH. Use _PATH_LOCALBASE here to ease
a consistent modification of this prefix.

- Hide ptsname_r under __BSD_VISIBLE for now as the specification
is not finalized at this time.
- Keep Symbol.map sorted.
- Avoid the interposing of ptsname_r(3) from an user application
from breaking ptsname(3) by making the implementation a static
method and call the static function from ptsname(3) instead.

getlogin_r is specified by POSIX to to take a size_t len, not int. Fix our
version to do the same, bump the symbol version due to ABI change and
provide compat.
This was reported to break compilation of Ruby 2.8.
Some discussion about the necessity of the ABI compat did take place in the
review. While many 64-bit platforms would likely be passing it in a 64-bit
register and zero-extended and thus, not notice ABI breakage, some do
sign-extend (e.g. mips).

The primary benefit is maintaining a completely shared
code base with the community allowing FreeBSD to receive
new features sooner and with less effort.
I would advise against doing 'zpool upgrade'
or creating indispensable pools using new
features until this change has had a month+
to soak.
Work on merging FreeBSD support in to what was
at the time "ZFS on Linux" began in August 2018.
I first publicly proposed transitioning FreeBSD
to (new) OpenZFS on December 18th, 2018. FreeBSD
support in OpenZFS was finally completed in December
2019. A CFT for downstreaming OpenZFS support in
to FreeBSD was first issued on July 8th. All issues
that were reported have been addressed or, for
a couple of less critical matters there are
pull requests in progress with OpenZFS. iXsystems
has tested and dogfooded extensively internally.
The TrueNAS 12 release is based on OpenZFS with
some additional features that have not yet made
it upstream.
Improvements include:
project quotas, encrypted datasets,
allocation classes, vectorized raidz,
vectorized checksums, various command line
improvements, zstd compression.
Thanks to those who have helped along the way:
Ryan Moeller, Allan Jude, Zack Welch, and many
others.

For libc regcomp, this will be a nop. libregex will take this to mean that
it needs to turn off GNU extensions, effectively switching it back to the
POSIX-compliant libc implementation at runtime.
