Check for it first. Only use /boot/zfs/zpool.cache if the /etc/zfs

e4584d4156 To avoid breakage for those who build/install without ZFS only

78bf7a79ba As of r364746 (OpenZFS import) existing ZPOOLs are not imported
prior to zvol and mountcritlocal resulting in ZVOLs (swap and
virtual machine UFS filesystems) being unavailable, leading to
boot failures.

We move the zpool import from zfs to a new zpool script, with the
-N option to avoid mounting datasets while making the ZPOOL's
datasets available for "legacy" mount (mountpoint=legacy) and ZVOLs
available for subsequent use for swap (in the zvol rc sript) or
for UFS or other filesystems in fstab(5), mounted by mountcritlocal.

1477dd823e Merge OpenZFS support in to HEAD.
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.

d2c07dbc46 Properly disable LUA_USE_DLOPEN for bootstrap flua
flua does have some specific bits that will include luaconf.h, but the
definition of LUA_USE_DLOPEN for those won't matter. This belongs in liblua
instead.

To expand on my previous commit, which was a little sparse with details,
it's not really safe to allow LUA_USE_DLOPEN with host lib paths being used.
The host system could have an entirely different lua version and this could
cause us to crash and burn.

If we want to revive this later, we need to make sure to define c module
paths inside OBJDIR that are compiled against whatever version we've
bootstrapped.

bd19a679a5 When booting a system with WITHOUT_IPFILTER the following errors

rcorder: requirement `ipfilter' in file `/etc/rc.d/securelevel' has no

Listing its own requrements in BEFORE rather than use REQUIRE of
non-optional scripts resolves this issue.

The issue was discovered and patched by glebius at Netflix.

In the last IFUNC related changes to rtld, the code that handled non-PLT
GNU IFUNC relocations ended up getting lost. This could leave some
relocations unhandled, causing crashes or misbehavior. This change restores
the handling of these relocations, but now together with the other IFUNC
relocations, allowing resolvers to reference external symbols.

This lets us parse/generate config files in the various formats supported by
libucl with flua.  For example, the following script will detect the format of
an object written to stdin as one of UCL config, JSON, or YAML and write it to
stdout as pretty-printed JSON:

local ucl = require('ucl')
local parser = ucl.parser()
parser:parse_string(io.read('*a'))
local obj = parser:get_object()
print(ucl.to_format(obj, 'json'))

2f9345080e rtld: set osrel when in the direct exec mode.
Rtld itself is a shared object which does not have vendor note, so
after the direct exec of ld-elf.so.1 process has p_osrel set to zero.
This affects the ABI of syscalls.

Set osrel to the __FreeBSD_version value at compile time right after
rtld identified direct exec mode.  Then, switch to the osrel read from
the binary note or zero if no note, right before starting calling
ifunc resolvers, which is the first byte of the user code.

6c255e9508 Add version indicators to rtld.
It is wrong to relate on __FreeBSD_version, either from
include/param.h, kernel, or libc, to check for rtld features.
Rtld might be from newer world than the running userspace.

Add special private symbols exported by rtld itself, to indicate the
changes in runtime behavior, and features that cannot be otherwise
detected or deduced at runtime.

Note that the symbols are not exported from libc, so they intentionally
cannot be linked against, and exported from the private namespace from rtld.
Consumers are required to use dlsym(3).  For instance, for
_rtld_version_laddr_offset, user should do
	ptr = dlsym(RTLD_DEFAULT, "_rtld_version_laddr_offset")
or even
	ptr = dlvsym(RTLD_DEFAULT,  "_rtld_version_laddr_offset",
	    "FBSDprivate_1.0");
Non-null ptr means that the change is present.

Also add _rtld_version__FreeBSD_version indicator to report the
headers version used at time of the rtld build.
