f4d987cd13 mk: WITH_FOO=no now generates a warning
Many people are used to gnu configure's behavior of changing
--with-foo=no to --without-foo. At the same time, several folks have
WITH_FOO=no in their config files to enable this ironic form of the
option because of an old meme from IRC, a mailing list or the forums (I
forget which). Add a warning to allow to alert people w/o breaking POLA.

25ecdc7d52 wpa: Restructure wpa build
The current WPA build assumes a flat namespace. However the latest sources
from w1.fi now have a duplicate config.c, in two separate subdirectories.
The flat namespace will overwrite config.o with the output from the most
recently modified config.c, of which there are two of them.

This commit resolves this problem by building each component in
wpa's src subdirectory tree into its own .a archive, just as the w1.fi
upstream build as used by the port does. The advantages of this approach
are:

1. Duplicate source file names, i.e. config.c in the wpa_supplicant
   direcory and another config.c in src/utils in the next wpa
   will result in both compiles writing to the same .o file.

2. This restructure simplifies maintanence. A develper needs only to add
   new files as identified by git status in the vendor branch to the
   appropriate Makefile within the usr.sbin/wpa tree. This also reduces
   time required to prepare a new import and should reduce error.

3. The new wpa build structure more closely represents the build as
   performed by the upstream tarball.

This is in preparation for the next wpa update from w1.fi.

This warning is very rarely useful (inline is a hint and not mandatory).

This flag was originally added in back in r94332 but the flag is a no-op

effect in Clang"). Removing it should make the GCC build output slightly

61f66a1f44 ncurses: Add support for terminfo database
Along with the termcap database, ncurses will now lookup for the
terminfo database, note that the terminfo database is being looked
up first and then it fallsback on the termcap one.

While here drop our custom reader for the termcap database, over the
time it is needed maintenance to be able to catchup with changes on ncurses
side.

Install the ncurses tools which are needed to deal with the terminfo
database: tic, infocmp, toe

Replace our termcap only aware tools with the ncurses counterpart:
tput, tabs, tset, clear and reset

In particular they can your the extra capabilities described in the
terminfo database, which does not exist in termcap

Note that to add a new terminfo information to the database from ports
the ports will just need to add their extra information into:
/usr/local/share/site-terminfo/<firstletteroftheterm>/<term>

9c6954329a bsd.compiler.mk: Detect distribution-provided GCC when executed as cc
Clang always prints "clang $VERSION" regardless of the name used to
execute it, whereas GCC prints "$progname $VERSION", meaning if CC is
set to cc and cc is GCC it will print "cc $VERSION". We are able to
detect some of those cases since it then prints "($PKGVERSION)", where
the default is "GCC", but many distributions override that to print
their name and the package version number (e.g. "Debian 10.2.1-6"), so
nothing tells us it's GCC other than the fact that it's not Clang (and
that there's an FSF copyright disclaimer).

However, GCC's -v option will always print "gcc version $VERSION", so
fall back on using that to detect GCC. Whilst Clang also supports this
option, we should never get here, so Clang handling is not added.

difficult.

Additionally, in the five plus years that it's been broken more reverse
dependencies have cropped up in libzstd, libsqlite3, and libcrypto (among
others) that make it more and more difficult to reconcile the effort needed
to fix these options.

986deea5b5 build: make check: use a PATH search instead for Kyua
which(1) accepts both relative/absolute paths as well as lone binary
names.  Set KYUA to kyua and use which(1) to confirm that it can find one;
if it cannot, just advise the user to set KYUA directly to the kyua binary
rather than assuming a relative location from LOCALBASE.

This allows `make check` to be operated with the version of kyua in base
without losing the flexibility of specifying another one.

ngie@ notes that the original intention was to avoid redundant $PATH lookups
and improve the determinism of the target. A future change will likely push
us back to this state, perhaps in the form of reverting this entirely and
just switching to using kyua in base. Accepting any in $PATH should be
considered a transitional move, at least until it's declared otherwise,
since kyua was only semi-recently added to base.

b82a9ec5f5 src.opts.mk: switch to bsdgrep as /usr/bin/grep

some day. Switch to the BSDL grep implementation now that it's been a
little more thoroughly tested and theoretically supports all of the
extensions that gnugrep in base had with our libregex(3).

Folks shouldn't really notice much from this update; bsdgrep is slower than
gnugrep, but this is currently the price to pay for fewer bugs. Those
dissatisfied with the speed of grep and in need of a faster implementation
should check out what textproc/ripgrep and textproc/the_silver_searcher
can do for them.

I have some WIP to make bsdgrep faster, but do not consider it a blocker
when compared to the pros of switching now (aforementioned bugs, licensing).

dabbf11f97 bsd.lib.mk: Work around build system raciness
We are seeing regular build failures due to libc.so being installed again and
another parallel make job tries to read the partially written libc.so at the
same time. When building with -j32 or higher this almost always happens on
the first clean build (subsequent incremental builds always work fine).
Using -S should "fix" the "section header table goes past the end of the
file: e_shoff = 0x..." errors that have started to plague our builds.

We originally thought this only affected CheriBSD, but I just got the same
error while building the latest upstream FreeBSD.

The real fix should be to not install libraries twice, but until then this
workaround is needed.

Original patch by jrtc27@, I only made some minor changes to the comment.

e268fd0a02 Support initializing stack variables on function entry
There are two options:
 - WITH_INIT_ALL_ZERO: Zero all variables on the stack.
 - WITH_INIT_ALL_PATTERN: Initialize variables with well-defined patterns.

The exact pattern are a compiler implementation detail and vary by type.
They are somewhat documented in the LLVM commit message:
https://reviews.llvm.org/rL349442
I've used WITH_INIT_ALL_* to match Microsoft's InitAll feature rather
than naming them after the LLVM specific compiler flags.

In a range of consumer products, options like these are used in
both debug and production builds with debugs builds using patterns
(intended to provoke crashes on use of uninitialized values) and
production using zeros (deemed more likely to lead to harmless
misbehavior or NULL-pointer dereferences).

e307eb94ae loader: zfs should support bootonce an nextboot
bootonce feature is temporary, one time boot, activated by
"bectl activate -t BE", "bectl activate -T BE" will reset the bootonce flag.

By default, the bootonce setting is reset on attempt to boot and the next
boot will use previously active BE.

By setting zfs_bootonce_activate="YES" in rc.conf, the bootonce BE will
be set permanently active.

bootonce dataset name is recorded in boot pool labels, bootenv area.

in case of nextboot, the nextboot_enable boolean variable is recorded in
freebsd:nvstore nvlist, also stored in boot pool label bootenv area.
On boot, the loader will process /boot/nextboot.conf if nextboot_enable
is "YES", and will set nextboot_enable to "NO", preventing /boot/nextboot.conf
processing on next boot.

bootonce and nextboot features are usable in both UEFI and BIOS boot.

To use bootonce/nextboot features, the boot loader needs to be updated on disk;
if loader.efi is stored on ESP, then ESP needs to be updated and
for BIOS boot, stage2 (zfsboot or gptzfsboot) needs to be updated
(gpart or other tools).

At this time, only lua loader is updated.

fe815331bb build: provide a default WARNS for all in-tree builds
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

Provide a default in src.sys.mk and set WARNS to it in bsd.sys.mk if that

no matter where you're building in the src tree without breaking things
outside of the tree.

Crunchgen has been updated as a bootstrap tool to work on this change
because it needs r365605 at a minimum to succeed. The cleanup necessary to

0e1e341b48 Stop using lorder and ranlib when building libraries
Use of ranlib or lorder is no longer necessary with current linkers
(probably anything newer than ~1990) and ar's ability to create an object
index and symbol table in the archive.
Currently the build system uses lorder+tsort to sort the .o files in
dependency order so that a single-pass linker can use them. However,
we can use the -s flag to ar to add an index to the .a file which makes
lorder unnecessary.
Running ar -s is equivalent to running ranlib afterwards, so we can also
skip the ranlib invocation.

Similarly, we don't have to pass the .o files for shared libraries in
dependency order since both ld.bfd and ld.lld will correctly resolve
references between the .o files.

This removes many fork()+execve calls for each library so should speed up
builds a bit. Additionally lorder.sh uses a regular expression that is not
supported by the macOS libc or glibc and results in many warnings when
cross-building (see D25989).

There is one functional change: lorder.sh removed duplicated .o files
from the linker command line which now no longer happens. I fixed the duplicates
in the base system in r364649. I also checked the ports tree for uses of
bsd.lib.mk and found one duplicate source file which I fixed in r548168.
Most ports use CMake/autotools rather than bsd.lib.mk but if this breaks any
ports that I missed in my search please let me know.

Avoiding the shell script actually speeds up the linking step noticeably: I
measured how long it takes to rebuild the .a and .so files for lib/libc using a
basic benchmark: `rm $LIBC_OBJDIR/*.so* $LIBC_OBJDIR/*.a* && /usr/bin/time make -DWITHOUT_TESTS -s > /dev/null`
Without this change ~4.5 seconds and afterwards ~3.1 seconds.
Looking at truss -cf output we can see that the number fork() system
calls goes down from 27 to 12 (and the speedup while tracing is more
noticeable: 81 seconds -> 65 seconds).

See also https://www.gnu.org/software/coreutils/manual/html_node/tsort-background.html
for some more background:
This whole procedure has been obsolete since about 1980, because Unix
archives now contain a symbol table (traditionally built by ranlib, now
generally built by ar itself), and the Unix linker uses the symbol table
to effectively make multiple passes over an archive file.

Or alternatively https://www.unix.com/man-page/osf1/1/lorder/:
The lorder command is essentially obsolete.  Use the following command in
its place: % ar -ts file.a

1d2a0dce33 [PowerPC] Remove obsolete MK_LOADER_FORCE_LE
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.)

  - Support for complex netmap options, such as external memory
    allocators or per-buffer offsets. This opens the way to future
    extensions.
  - More flexibility in the netmap port bind options, such as
    non-numeric names for pipes, or the ability to specify the netmap
    allocator that must be used for a given port.
  - Automatic tracking of the netmap memory regions in use across the
    open ports.

489377c0a4 Avoid recomputing COMPILER_/LINKER_ variables when set explicitly
I noticed that when we build libraries for a different ABI (in CheriBSD) we
were calling ${XCC}/${LD} --version for every directory. It turns out that
this was caused by bsd.compat.mk explicitly setting (X_)COMPILER variables
for that build stage and this stops the _can_export logic from working.
To fix this, we change the check to only set _can_export=no if the variable
is set and it is set to a different value than the cached value.
This noticeably speeds up the tree walk while building compat libraries.
During an upstream amd64 buildworld this also removes 8 --version calls.

2b6ee34cf6 Pass -fuse-ld=/path/to/ld if ${LD} != "ld"
This is needed so that setting LD/XLD is not ignored when linking with $CC
instead of directly using $LD. Currently only clang accepts an absolute
path for -fuse-ld= (Clang 12+ will add a new --ld-path flag), so we now
warn when building with GCC and $LD != "ld" since that might result in the
wrong linker being used.

We have been setting XLD=/path/to/cheri/ld.lld in CheriBSD for a long time and
used a similar version of this patch to avoid linking with /usr/bin/ld.
This change is also required when building FreeBSD on an Ubuntu with Clang:
In that case we set XCC=/usr/lib/llvm-10/bin/clang and since
/usr/lib/llvm-10/bin/ does not contain a "ld" binary the build fails with
`clang: error: unable to execute command: Executable "ld" doesn't exist!`
unless we pass -fuse-ld=/usr/lib/llvm-10/bin/ld.lld.

This change passes -fuse-ld instead of copying ${XLD} to WOLRDTMP/bin/ld
since then we would have to ensure that this file does not exist while
building the bootstrap tools. The cross-linker might not be compatible with
the host linker (e.g. when building on macos: host-linker= Mach-O /usr/bin/ld,
cross-linker=LLVM ld.lld).

Work on merging FreeBSD support in to what was
at the time "ZFS on Linux" began in August 2018.

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.

1a18ab420b Allow overriding the tool used for stripping binaries
Since the make variable STRIP is already used for other purposes, this
uses STRIPBIN (which is also used for the same purpose by install(1).
This allows using LLVM objcopy to strip binaries instead of the in-tree
elftoolchain objcopy. We make use of this in CheriBSD since passing
binaries generated by our toolchain to elftoolchain strip sometimes results
in assertion failures.

This allows working around https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=248516
by specifying STRIPBIN=/path/to/llvm-strip

2192efc03b RISC-V boot1.efi and loader.efi support
This implementation doesn't have any major deviations from the other EFI
ports. I've copied the boilerplate from arm and arm64.

I've tested this with the following boot flows:
OpenSBI (M-mode) -> u-boot (S-mode) -> loader.efi -> FreeBSD
OpenSBI (M-mode) -> u-boot (S-mode) -> boot1.efi -> loader.efi -> FreeBSD

Due to the way that u-boot handles secondary CPUs, OpenSBI >= v0.7 is required,
as the HSM extension is needed to bring them up explicitly. Because of this,
using BBL as the SBI implementation will not be possible. Additionally, there
are a few recent u-boot changes that are required as well, all of which will be
present in the upcoming v2020.07 release.

252884ae7e Import new 2-clause BSD licenced implementation of the bc and dc commands
These implementations of the bc and dc programs offer a number of advantages
compared to the current implementations in the FreeBSD base system:

- They do not depend on external large number functions (i.e. no dependency
  on OpenSSL or any other large number library)

- They implements all features found in GNU bc/dc (with the exception of
  the forking of sub-processes, which the author of this version considers
  as a security issue).

- They are significantly faster than the current code in base (more than
  2 orders of magnitude in some of my tests, e.g. for 12345^100000).

- They should be fully compatible with all features and the behavior of the
  current implementations in FreeBSD (not formally verified).

- They support POSIX message catalogs and come with localized messages in
  Chinese, Dutch, English, French, German, Japanese, Polish, Portugueze,
  and Russian.

- They offer very detailed man-pages that provide far more information than
  the current ones.

The upstream sources contain a large number of tests, which are not
imported with this commit. They could be integrated into our test
framework at a latter time.

Installation of this version is controlled by the option "MK_GH_BC=yes".
This option will be set to yes by default in 13-CURRENT, but will be off
by default in 12-STABLE.

483d953a86 Initial support for bhyve save and restore.
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.

8eb1a0ce56 Add -fno-common to all userland/kernel src builds
-fno-common will become the default in GCC10/LLVM11. Plenty of work has been
put in to make sure our world builds are no -fno-common clean, so let's slap
the build with this until it becomes the compiler default to ensure we don't
regress.

At this time, we will not be enforcing -fno-common on ports builds. I
suspect most ports will be or quickly become -fno-common clean as they're
naturally built against compilers that default to it, so this will hopefully
become a non-issue in due time. The exception to this, which is actually the
status quo, is that kmods built from ports will continue to build with
-fno-common.

As of the time of writing, I intend to also make stable/12 -fno-common
clean. What's been done will be MFC'd to stable/11 if it's easily applicable
and/or not much work to massage it into being functional, but I anticipate
adding -fcommon to stable/11 builds to maintain its ability to be built with
newer compilers for the rest of its lifetime instead of putting in a third
branch's worth of effort.

147d7b567f llvm: add a build knob for enabling assertions
For head/, this will remain eternally default-on to maintain the status quo.

There's value in being able to flip it one way or the other easily on head
or stable branches, whether you want to gain some performance back on head/
(for machines there's little chance you'll actually hit an assertion) or
potentially diagnose a problem with the version of llvm on an older branch.

In-tree gdb is essentially obsolete.  We kept it for sparc64 (because
gdb in ports lacked sparc64 support) and as a fallback for crashinfo.
gdb was installed to /libexec on all archs other than sparc64, where the
WITHOUT_GDB_LIBEXEC option was default, with gdb installed to /usr/bin.
With sparc64's retirement WITH_GDB_LIBEXEC became the default for all
architectures, but it was still possible to set it off and install gdb
into /usr/bin.

As the next step in gdb's retirement, remove the option and install gdb
only into /libexec as the crashinfo fallback. We expect users to install
the gdb port or package for debugging. The in-tree gdb lacks support for
a number of supported architectures and does not support contemporary

d64b2df932 src.opts.mk: drop C++11 compiler conditional from OPENMP
We no longer support older C++ compilers, so do not need to explicitly
test for C++11 support.

After r339946 we stopped running `cc --version` during cleandir/obj
stages, so stopped setting COMPILER_FEATURES.  This in turn meant
lib/libomp was excluded from the clean stage in a normal buildworld
(i.e., one without -DNO_CLEAN), and this is what caused recent build
failures with errors about missing ittnotify_static.c.

This commit should obviate the need for the workaround committed in
r359083.  Thanks to bdrewery for the insight and for pushing for a
correct fix.  There are more cleanups to be done, but this change is
a simplification and an improvement over r359083.

afc571b1a6 veloader use vectx API for kernel and modules
The vectx API, computes the hash for verifying a file as it is read.
This avoids the overhead of reading files twice - once to verify, then
again to load.

For doing an install via loader, avoiding the need to rewind
large files is critical.

This API is only used for modules, kernel and mdimage as these are the
biggest files read by the loader.
The reduction in boot time depends on how expensive the I/O is
on any given platform.  On a fast VM we see 6% improvement.

For install via loader the first file to be verified is likely to be the
kernel, so some of the prep work (finding manifest etc) done by
verify_file() needs to be factored so it can be reused for
vectx_open().

For missing or unrecognized fingerprint entries, we fail
in vectx_open() unless verifying is disabled.

Otherwise fingerprint check happens in vectx_close() and
since this API is only used for files which must be verified
(VE_MUST) we panic if we get an incorrect hash.

GPL dtc now has FreeBSD CI support via Cirrus-CI to help ensure it
continues to build/work on FreeBSD and is available in the ports tree
if needed.

The copy of (copyfree licensed) libfdt that we actually use is in
sys/contrib/libfdt so the extra copy under contrib/dtc/libfdt can be
removed along with the rest of the GPL dtc.

57f804675e remove GCC 4.2.1 build infrastructure
As described in Warner's email message[1] to the FreeBSD-arch mailing
list we have reached GCC 4.2.1's retirement date.  At this time all
supported architectures either use in-tree Clang, or rely on external
toolchain (i.e., a contemporary GCC version from ports).

GCC 4.2.1 was released July 18, 2007 and was imported into FreeBSD later
that year, in r171825.  GCC has served us well, but version 4.2.1 is
obsolete and not used by default on any architecture in FreeBSD.  It
does not support modern C and does not support arm64 or RISC-V.

Thanks to everyone responsible for maintaining, updating, and testing
GCC in the FreeBSD base system over the years.

So long, and thanks for all the fish.

eb834d9f1b Take LINKER_FREEBSD_VERSION from numerical field after dash
Summary:
With COMPILER_FREEBSD_VERSION, we use a numeric value that we bump each
time we make a change that requires re-bootstrapping, but with the
linker variant, we instead take the entire part after "FreeBSD", as in
this example version output:

LLD 9.0.1 (FreeBSD c1a0a213378a458fbea1a5c77b315c7dce08fd05-1300006) (compatible with GNU linkers)

E.g., LINKER_FREEBSD_VERSION is currently being set to
"c1a0a213378a458fbea1a5c77b315c7dce08fd05-1300006".  This means that
*any* new upstream lld version will cause re-bootstrapping.

We should only look at the numerical field we append after a dash
instead.  This review attempts to make it so.

The only thing I am not happy about is the post-processing of awk output
in Makefile.inc1.  I notice that our awk does not have gensub(), so it
can't substitute a numbered sub-regex with \1, \2, etc.  Suggestions
welcome. :)

For now, silence the warning using -Wno-deprecated-copy.

The second issue is because one of the googlemock test programs attempts

dea247463c Add note to remind me there are three choices for arm32 floating point.
hard	use floating point hardware, pass registers to functions in
	floating point registers.
softfp	use floating point hardware, but pass registers to functions
	in integer registers.
soft	do floating point calcuations without using floating point
	hardware. Pass arguments in integer registers.

FreeBSD 11 and newer assumes hard. 10 and earlier assumed softfp.  We have no
real support, at the moment, for soft. It's untested, though, if softfp still
works.

Add a note here since this is a whack-a-doodle combination relative to all other
platforms.

softfp is likely to go away in the future because it was retained for people
using FreeBSD 10 + armv6 needing to transition more slowly from softfp -> hard
than the project. It likely is no longer needed, and may be getting in the
way of people needing 'soft' support.

d679c71970 Refine fusefs test workaround for mips+llvm
This re-enables building the googletest suite by default on mips and instead
specifically doesn't build fusefs tests for mips+clang builds.  clang will
easily spent >= 1.5 hours compiling a single file due to a bug in
optimization (see LLVM PR 43263), so turn these off for now while that's
hashed out.

GCC builds are unaffected and build the fusefs tests as-is. Clang builds
only happen by early adopters attempting to hash out the remaining issues.

The comment has been updated to reflect its new position and use less strong
wording about imposing on people.

Extend r356379 to include 32-bit mips and sparc64.  Using a decade-old

a combination unlikely to be used by anyone else, and it's not going

b451cd4544 [PowerPC64] Use ld.bfd to build LIB32 and STAND - when using llvm
Summary:
This patch is to support ongoing work for replacing "GCC/BFD" by "CLANG/LLD" on
target PowerPC64 [1], by proposing a way to specify and/or locate a secondary
ld.bfd linker.
This is necessary as LLD currently doesn't support PowerPC 32 bits, so we keep
using BFD for the 32 bit stuff on PowePC64(LIB32 compatibility and
STAND/slof/loader.)

- creates LD_BFD variable pointing to ld.bfd
- use LD_BFD as linker for LIB32/compat
- Default behavior for other platforms aren't changed.

506f364029 Add flua to the base system, install to /usr/libexec
FreeBSDlua ("flua") is a FreeBSD-private lua, flavored with whatever
extensions we need for base system operations. We currently support a subset
of lfs and lposix that are used in the rewrite of makesyscall.sh into lua,
added in r354786.

flua is intentionally written such that one can install standard lua and
some set of lua modules from ports and achieve the same effect.

linit_flua is a copy of linit.c from contrib/lua with lfs and lposix added
in. This is similar to what we do in stand/. linit.c has been renamed to
make it clear that this has flua-specific bits.

luaconf has been slightly obfuscated to make extensions more difficult. Part
of the problem is that flua is already hard enough to use as a bootstrap
tool because it's not in PATH- attempting to do extension loading would
require a special bootstrap version of flua with paths changed to protect
the innocent.

src.lua.mk has been added to make it easy for in-tree stuff to find flua,
whether it's bootstrap-flua or relying on PATH frobbing by Makefile.inc1.

6ab18ea64d Build toolchain components as dynamically linked executables by default
Summary:
Historically, we have built toolchain components such as cc, ld, etc as
statically linked executables.  One of the reasons being that you could
sometimes save yourself from botched upgrades, by e.g. recompiling a
"known good" libc and reinstalling it.

In this day and age, we have boot environments, virtual machine
snapshots, cloud backups, and other much more reliable methods to
restore systems to working order.  So I think the time is ripe to flip
this default, and link the toolchain components dynamically, just like
almost all other executables on FreeBSD.

Maybe at some point they can even become PIE executables by default! :)

f9cb60c649 bsd.compat.mk isn't setup to be included outside of Makefile.inc so comment it
out here until that's sorted out. Otherwise the build is broken. when
TARGET_ARCH isn't defined.

6b53d51078 Add the ability to link programs against a compat ABI.
Linkage is controlled by two make knobs:
	WANT_COMPAT - Prefer to link against the compat ABI.
	NEED_COMPAT - Link against the compat ABI or fail to build.

Supported values are "32", "soft", and "any".  The latter meaning pick
the first[0] supported compat ABI.

This can be used to provide test binaries for compat ABIs or to link
ABI-specific programs.

[0] We currently support only one compat ABI at a time, but this may
change in the future and some code in this commit is structured to ease
that change.

1a13f2e6b4 Introduce stats(3), a flexible statistics gathering API.
This provides a framework to define a template describing
a set of "variables of interest" and the intended way for
the framework to maintain them (for example the maximum, sum,
t-digest, or a combination thereof).  Afterwards the user
code feeds in the raw data, and the framework maintains
these variables inside a user-provided, opaque stats blobs.
The framework also provides a way to selectively extract the
stats from the blobs.  The stats(3) framework can be used in
both userspace and the kernel.

See the stats(3) manual page for details.

This will be used by the upcoming TCP statistics gathering code,
https://reviews.freebsd.org/D20655.

The stats(3) framework is disabled by default for now, except
in the NOTES kernel (for QA); it is expected to be enabled
in amd64 GENERIC after a cool down period.

036d2e814b Re-add ALLOW_MIPS_SHARED_TEXTREL, sprinkle it around
Diff partially stolen from CheriBSD; these bits need -Wl,-z,notext in order
to build in an LLVM world. They are needed for all flavors/sizes of MIPS.
This will eventually get fixed in LLVM, but it's unclear when.

982f1fc2d8 Override the TLS model when building mips64 binaries and static libraries
GCC uses "dynamic" TLS models when -fpic or -fPIC is explicitly
specified on the command line (which is only true for shared libraries).
It uses "static" (or "exec") TLS models otherwise.  In particular, GCC
does _not_ use dynamic TLS models when PIC is implicitly enabled (which
it is on MIPS), only if a PIC flag is explicitly provided.

llvm uses "dynamic" TLS models if PIC is enabled either via a PIC flag
or if it is implicily enabled (as on MIPS64).  This means that llvm on
MIPS64 always uses "dynamic" TLS models.  However, dynamic TLS models
do not work for static binaries and libraries as the __tls_get_addr
function they invoke is only defined in rtld.

f27f39db77 [1/3] Initial infrastructure for SSL root bundle in base
This setup will add the trusted certificates from the Mozilla NSS bundle
to base.

This commit includes:
- CAROOT option to opt out of installation of certs
- mtree amendments for final destinations
- infrastructure to fetch/update certs, along with instructions

A follow-up commit will add a certctl(8) utility to give the user control
over trust specifics. Another follow-up commit will actually commit the
initial result of updatecerts.

This work was done primarily by allanjude@, with minor contributions by
myself.

2d0a92c9ab Move simple_httpd out of picobsd, add HTTPD option (default OFF)
picobsd/tinyware has had this compact HTTPD server for a long time, and some
people do use it. Move it out into usr.sbin well in advance of any action
being taken on picobsd.

This has been gated behind an HTTPD option defaulted to *off*, primarily for
two reasons:
1.) This code likely needs a good audit, as it's been living off in picobsd
    land for a long time, and
2.) We don't currently ship an httpd and this may not be a welcome surprise.
