100353cfbf Add virtio-9p (aka VirtFS) filesystem sharing to bhyve.
VirtFS allows sharing an arbitrary directory tree between bhyve virtual
machine and the host. Current implementation has a fairly complete support
for 9P2000.L protocol, except for the extended attribute support. It has
been verified to work with the qemu-kvm hypervisor.

afd95785c0 newlocale(3): Fix a memory leak.
newlocale() optionally takes a "base" locale, from which components not
specified in the mask are inherited.  POSIX says that newlocale() may
modify "base" and return it, or free "base" and return a newly allocated
locale.  We were not doing either, so applications which use newlocale()
to modify an existing base locale end up leaking memory on FreeBSD.

This diff fixes the leak by releasing a reference to the base locale
before returning.  This is less efficient than modifying "base"
directly, but is simpler for an initial bug fix.  Also, update the man
page to clarify behaviour with respect to "base".

da6e5efe92 libmd: add dependency workaround for r366344
r366344 fixed and reenabled the assembly optimized skein implementation,
but skein_block objects were not being rebuilt in no-clean builds. This
resulted in failing no-clean builds. SKEIN_USE_ASM controls which
routines come from C vs assembly, and with no explicit dependency
r366344's change to SKEIN_USE_ASM did not cause skein_block.{o,pico}
to be rebuilt.

Add a dependency on this Makefile for the skein_block objects. This
dependency is broader in scope than absolutely required (that is, the
skein_block objects will now be rebuilt on any change to this Makefile).
There are ways this could be addressed, but it is probably not worth the
additional effort or testing time to pursue them.

320ef1bef0 auxv: partially revert r366207, cast buflen to unsigned int as needed
The warning generated pre-r366207 is actually a sign comparison warning:

error: comparison of integers of different signs: 'unsigned long' and 'int'
                        if (strlcpy(buf, execpath, buflen) >= buflen)

Revert parts that affected other lines and just cast this to unsigned int.

The buflen < 0 -> EINVAL has been kept despite no longer serving any
purposes w.r.t. sign-extension because I do believe it's the right thing to
do: "The provided buffer was not the right size for the requested item."

The original warning is confirmed to still be gone with an:
env WARNS=6 make WITHOUT_TESTS=yes.

7cc42f6d25 Do a sweep and remove most WARNS=6 settings
Repeating the default WARNS here makes it slightly more difficult to
experiment with default WARNS changes, e.g. if we did something absolutely
bananas and introduced a WARNS=7 and wanted to try lifting the default to
that.

Drop most of them; there is one in the blake2 kernel module, but I suspect
it should be dropped -- the default WARNS in the rest of the build doesn't
currently apply to kernel modules, and I haven't put too much thought into
whether it makes sense to make it so.

bceb5a2c8d [PowerPC64LE] Pass our byte order to the sqlite3 build.
Due to the sqlite3 endian detection code preferring to check platform defines
instead of checking endian defines, it is necessary to manually set
the endianness on PowerPC64LE.

Unlike other bi-endian platforms, PowerPC64LE relies entirely on the
generic endianness macros like __BYTE_ORDER__ and has no platform-specific
define to denote little endian.

Add -DSQLITE_BYTEORDER=1234 to the CFLAGS when building libsqlite3 on
powerpc64le.

Fixes runtime operation of sqlite on PowerPC64LE.

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
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.

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
successfully walk over this change on WITHOUT_CLEAN builds has been added.

There is a supplemental project to this to list all of the warnings that are
encountered when the environment has WARNS=6 NO_WERROR=yes:
https://warns.kevans.dev -- this project will hopefully eventually go away
in favor of CI doing a much better job than it.

72f97a2d09 libarchive: fix mismatch between library and test configuration
I was investigating libarchive test failures on CheriBSD and it turns out
we get a reproducible SIGBUS for test_archive_m5, etc. Debugging this shows
that libarchive and the tests disagree when it comes to the definition of
archive_md5_ctx: libarchive assumes it's the OpenSSL type whereas the test
use the libmd type. The latter is not necessarily aligned enough to store
a pointer (16 bytes for CHERI RISC-V), so we were crashing when storing
EVP_MD_CTX* to an 8-byte-aligned archive_md5_ctx.

To avoid problems like this in the future, factor out the common compiler
flags into a Makefile.inc and include that from the tests Makefile.

8b8cf4ece6 memfd_create: simplify HUGETLB support a little bit
This also fixes a minor issue that was missed in the initial review; the
layout of the MFD_HUGE_* flags is actually not 1:1 bit:flag -- it instead
borrowed the Linux convention of how this is laid out since it was
originally implemented on Linux, the top 6 bits represent the shift required
for the requested page size.

This allows us to remove the flag <-> pgsize mapping table and simplify the
logic just prior to validation of the requested page size.

While we're here, fix two small nits:

- HUGETLB memfd shouldn't exhibit the SHM_GROW_ON_WRITE behavior. We can
  only grow largepage shm by appropriately aligned (i.e. requested pagesize)
  sizes, so it can't work in the typical/sane fashion. Furthermore, Linux
  does the same, so let's be compatible.

- We don't allow MFD_HUGETLB without specifying a pagesize, so no need to
  check for that later.

5593499d4a libc/resolv: attempt to fix the test under WARNS=6
In a side-change that I'm working on to start defaulting src builds to
WARNS=6 where WARNS isn't otherwise specified, GCC6 (and clang, to a lesser
extent) pointed out a number of issues with the resolv tests:

- Global method variable that gets shadowed in run_tests()
- Signed/unsigned comparison between i in run_tests() and hosts->sl_cur

The shadowed variable looks like it might actually be bogus as written, as
we pass it to RUN_TESTS -> run_tests, but other parts use the global method
instead. This change is mainly geared towards correcting that by removing
the global and plumbing the method through from run_tests -> run into the
new thread.

For the signed/unsigned comparison, there's no compelling reason to not just
switch i/nthreads/nhosts to size_t.

The review also included a change to the load() function that was better
addressed by jhb in r365302.

It seems more consistent to turn this into a regular src.conf(5) option,

be toggled similar to any other source build option, and turned on or
