The Ubuntu /bin/sh (dash) removes all environment variables that contain
characters outside the [a-zA-Z0-9_] range and this breaks the bmake tests that
run as part of bootstrapping bmake.
This can be reverted when the bmake tests have been updated.
This makes it possible to compile on non-FreeBSD systems since make will
usually be GNU make there. Even if they include bmake, it will often
either be a broken version or too old to build FreeBSD.
This should be the last commit needed to compile FreeBSD on Linux+macOS.
After over two years, I've finally managed to upstream all our local CheriBSD
changes to allow building on Linux (and as a result of being reviewed by more
people they are slightly less ugly than they were before).
It should now be possible to run the following to build on Linux+macOS if you
have LLVM/Clang 10 or newer installed:
MAKEOBJDIRPREFIX=/somewhere ./tools/build/make.py TARGET=amd64 TARGET_ARCH=amd64 buildworld
I have only tested macOS 15, Ubuntu 18.04 and openSUSE Leap, but other Linux
distributions might also work (as long as they ship a recent GLibc and compiler).

The current default is provided in various Makefile.inc in some top-level
directories and covers a good portion of the tree, but doesn't cover parts
of the build a little deeper (e.g. libcasper).
Provide a default in src.sys.mk and set WARNS to it in bsd.sys.mk if that
variable is defined. This lets us relatively cleanly provide a default WARNS
no matter where you're building in the src tree without breaking things
outside of the tree.

In D12421, the ability to compile stand/ in little-endian was added, with the
intention to extend loader.kboot to run in Petitboot.
However, no further work was done, as the kernel then gained self-execution
capabilities as Petitboot was taught to load FreeBSD kernels directly.
The FreeBSD installer on powerpc64 (on POWER8 and POWER9) uses
/boot/etc/kboot.conf instead of loader.
As this option does nothing but cause stand/ to be miscompiled and actively
causes confusion, remove it.
(I have a functioning petitboot loader in my local tree, however, it turned
out to be quite inconvient to use due to the current petitboot plugin design
so I put it on hold.)

Currently, WITHOUT_PORTSNAP forces WITHOUT_FREEBSD_UPDATE because the
latter relies on phttpget, which lives inside the portsnap build bits.
Remove the dependency between these two options by moving phttpget out into

WITH_FREEBSD_UPDATE.
Future work could remove the conditional if it's decided that users will use

For historical reasons, defining MALLOC_PRODUCTION in /etc/make.conf has
been used to turn off potentially expensive debug checks and statistics
gathering in the implementation of malloc(3).
It seems more consistent to turn this into a regular src.conf(5) option,
e.g. WITH_MALLOC_PRODUCTION / WITHOUT_MALLOC_PRODUCTION. This can then
be toggled similar to any other source build option, and turned on or
off by default for e.g. stable branches.

The most awkward bit in this patch is the bootstrapping of m4:
We can't simply use the host version of m4 since that is not compatible
with the flags passed by lex (at least on macOS, possibly also on Linux).
Therefore we need to bootstrap m4, but lex needs m4 to build and m4 also
depends on lex (which needs m4 to generate any files). To work around this
cyclic dependency we can build a bootstrap version of m4 (with pre-generated
files) then use that to build the real m4.
This patch also changes the xz/unxz/dd tools to always use the host version
since the version in the source tree cannot easily be bootstrapped on macOS
or Linux.

Although I can't reproduce it, others are seeing different lex/yacc
programs always regenerated after my change to copy rather than
symlink the files. The reported fix is to add '-p' to the copies.
Since it doesn't hurt, go head and add it, though the reasons for
this mattering remain at best obscure and poorly articulated.
The -P flag is required by POSIX so we don't have to care whether pwd is
a shell builtin or not. This also allows removing pwd from the list of
bootstrap tools since all shells we care about for building have a
builtin pwd command. This effectively reverts r364190.
Suggested By: rgrimes, jrtc27
After r364166 and r364174, crunchgen needs a pwd binary in $PATH instead
of using a hardcoded absolute path. This commit is needed for
BUILD_WITH_STRICT_TMPPATH builds (currently not on by default).
make copies instead.
There's too many times that we can't run the new binaries with old
libraries. Making the links when things are known to be 'safe' is a
nice optimization, but a copy of all the binaries is only 30MB, so
saving the copies at the cost of increased support when new symbols
are added and used as part of the bootstrap seems to be unwise.
There may be additional optimizations possible here, especially for
!FreeBSD hosts. However, that's beyond the scope of the problem I'm
trying to fix with make failing mid-way through an installworld across
change r363679. This optimization there caused us to run a new binary
with an old library once a new make was installed due to the symbolic
link. One could just copy make, but then other binaries fail as well,
so rather than play whack-a-mole, I opted to take us back to the old
way. Before r340157 or so we did copies (thogh of a lot fewer
artifacts), and we didn't have issues like this.

Save and restore (also known as suspend and resume) permits a snapshot
to be taken of a guest's state that can later be resumed. In the
current implementation, bhyve(8) creates a UNIX domain socket that is
used by bhyvectl(8) to send a request to save a snapshot (and
optionally exit after the snapshot has been taken). A snapshot
currently consists of two files: the first holds a copy of guest RAM,
and the second file holds other guest state such as vCPU register
values and device model state.
To resume a guest, bhyve(8) must be started with a matching pair of
command line arguments to instantiate the same set of device models as
well as a pointer to the saved snapshot.
While the current implementation is useful for several uses cases, it
has a few limitations. The file format for saving the guest state is
tied to the ABI of internal bhyve structures and is not
self-describing (in that it does not communicate the set of device
models present in the system). In addition, the state saved for some
device models closely matches the internal data structures which might
prove a challenge for compatibility of snapshot files across a range
of bhyve versions. The file format also does not currently support
versioning of individual chunks of state. As a result, the current
file format is not a fixed binary format and future revisions to save
and restore will break binary compatiblity of snapshot files. The
goal is to move to a more flexible format that adds versioning,
etc. and at that point to commit to providing a reasonable level of
compatibility. As a result, the current implementation is not enabled
by default. It can be enabled via the WITH_BHYVE_SNAPSHOT=yes option
for userland builds, and the kernel option BHYVE_SHAPSHOT.
