529f0e6c74 vt/ofwfb: Fix brain-o from r336514, use the correct form of /chosen/stdout-path
/chosen/stdout-path is a string, not ihandle.  Treat it as such.

With this, ofwfb now starts correctly on a POWER9 system when launched from
the local console (not serial).

2cc27fc069 vt/ofwfb: Check that /chosen/stdout is valid before using it in initialization
The FDT implementation of OF_instance_to_package() backend checks the
cross-reference to get the node.  On failure, this returns the input handle
unchanged.  In the case of ofwfb attachment, if /chosen/stdout property does not
exist, sc->sc_handle is either garbage or 0, which then gets propagated to node.
This will prevent "screen" from being used, resulting in not properly attaching.
Correct this by matching the code in ofwfb_probe().

1538208322 Support installing manpages for multiple or alternate architecture(s).
Some section-4 manpages are architecture-specific, and the build process
currently generates only the pages for the MACHINE_CPUARCH being built.
man(1) supports a '-m' option to find manpages belonging to an arbitrary
architecture other than the MACHINE_[CPU]ARCH, but we have no way to
generate and install alternate-arch pages right now.

This change adds a new make.conf variable, MAN_ARCH, which can be a list of
one or more MACHINE_ARCH or MACHINE_CPUARCH values. All arch-specific
manpages that exist for the named arches will be installed. If unset, it
continues the behavior of installing just the MACHINE_CPUARCH being built.

d11f4dfd21 Automatically run ntpd as non-root when possible.
Ntpd needs only a subset of full root privileges to do its job. Specifically
it needs the ability to manipulate system time, and to re-bind to a
privileged UDP port after interface changes. The mac_ntpd(4) policy module
(see r336525) can grant these privs.

These changes detect the availability of mac_ntpd(4). If enabled, and if the
ntpd configuration is fairly vanilla, it automatically runs ntpd as the
non-root user 'ntpd' (uid 123). "Vanilla" means the config doesn't include
command line or ntp.conf options changing the location of files or using any
files/dirs likely to be inaccessible to user ntpd.  Ntpd can still run as
non-root when using such options, but the admin must ensure all required
files and dirs are accessible, and then set ntpd_user=ntpd in rc.conf.

Note that these changes also address PR 199127 by using the command_args
technique suggested in the patch. They also tangentially address PR 113552,
which is primarily about inconsistent filenames in documentation, but some
of the inconsistancy was caused by old code in rc.d/ntpd which is leftover
from the intial import from netbsd. There was code to do chroot setup which
required the use of the netbsd clockctl(4) device; that code never had any
effect on freebsd, because we lack that device and don't build ntpd with the
options that would allow using it.

27aa844253 Centralize the complications for special efficient rounding to integers.
This was open-coded in range reduction for trig and exp functions.  Now
there are 3 static inline functions rnint[fl]() that replace open-coded
expressions, and type-generic irint() and i64rint() macros that hide the
complications for efficiently using non-generic irint() and irintl()
functions and casts.

Special details:

ld128/e_rem_pio2l.h needs to use i64rint() since it needs a 46-bit integer
result.  Everything else only needs a (less than) 32-bit integer result so
uses irint().

Float and double cases now use float_t and double_t locally instead of
STRICT_ASSIGN() to avoid bugs in extra precision.

On amd64, inline asm is now only used for irint() on long doubles.  The SSE
asm for irint() on amd64 only existed because the ifdef tangles made the
correct method of simply casting to int for this case non-obvious.

1a59bccc42 Set SO_SNDTIMEO in the client side krpc when CLSET_TIMEOUT is done.
During testing of the pNFS client, it was observed that an RPC could get
stuck in sosend() for a very long time if the network connection to a DS
had failed. This is fixed by setting SO_SNDTIMEO on the TCP socket.
This is only done when CLSET_TIMEOUT is done and this is not done by any
use of the krpc currently in the source tree, so there should be no effect
on extant uses.
A future patch will use CLSET_TIMEOUT for TCP connections to DSs.

060679ef9c Collapse zfsloader functionality back down into loader.
We no longer really need a separate zfsloader. It was useful when we
were first supporting ZFS and had limited ability to properly boot off
of ZFS without the special boot loader. Now that the boot loader has
matured, go the way loader.efi pioneered and just build one
binary. Change the name of the loader to load in the secondary boot
blocks to be just /boot/loader. Provide a symbolic link from zfsloader
to loader so people who have not upgraded their boot blocks are not
affected. This has the happy benefit of making coexistence easier as
well (fewer binaries in the matrix).

e236f904b2 cryptocheck: Correct mismatch between OpenSSL use and OCF Blake2
This corrects a mistake introduced to the cryptocheck tool in r331418.

Our CRYPTO_BLAKE2B and CRYPTO_BLAKE2S algorithms refer to either the plain,
unkeyed hashes (specified with cri_klen = 0), or a Blake2-specific keyed MAC
(when a cri_key is provided).

In contrast, OpenSSL's Blake2 algorithms only provide the plain hash.
Cryptocheck's T_HMAC corresponds to OpenSSL's HMAC() routine, which is the
ordinary HMAC construction applied to any plain, unkeyed hash.  We don't
have any HMAC-Blake2 cipher modes in OCF, so fix the test to only test
Blake2 as a plain hash.

(Ideally we would test keyed Blake2 as well, but that is left as future
work.)

3496c981ac Make it possible to run ntpd as a non-root user, add ntpd uid and gid.
Code analysis and runtime analysis using truss(8) indicate that the only
privileged operations performed by ntpd are adjusting system time, and
(re-)binding to privileged UDP port 123. These changes add a new mac(4)
policy module, mac_ntpd(4), which grants just those privileges to any
process running with uid 123.

This also adds a new user and group, ntpd:ntpd, (uid:gid 123:123), and makes
them the owner of the /var/db/ntp directory, so that it can be used as a
location where the non-privileged daemon can write files such as the
driftfile, and any optional logfile or stats files.

Because there are so many ways to configure ntpd, the question of how to
configure it to run without root privs can be a bit complex, so that will be
addressed in a separate commit. These changes are just what's required to
grant the limited subset of privs to ntpd, and the small change to ntpd to
prevent it from exiting with an error if running as non-root.

7fb935da15 Merge the md_page structs for AIM and Book-E into a single unioned struct
Summary:
Ports like sysutils/lsof troll through kernel structures, and
therefore include kernel headers and all the dirty secrets involved.  struct
vm_page includes the struct md_page inline, which currently is only defined
if AIM or BOOKE is defined.  Thus, by default, sysutils/lsof cannot build,
due to the struct md_page having an incomplete type.  Fix this by merging
the two struct definitions into an anonymous struct-union.

A similar change could be made to unify the pmap structures as well.

103cc0f6ea Revert r329254. The underlying cause for the copy-on-write problem in
multithreaded programs that was addressed by r329254 was in the
implementation of pmap_enter() on some architectures, notably, amd64.
kib@, markj@ and I have audited all of the pmap_enter() implementations,
and fixed the broken ones, specifically, amd64 (r335784, r335971), i386
(r336092), mips (r336248), and riscv (r336294).

To be clear, the reason to address the problem within pmap_enter() and
revert r329254 is not just a matter of principle.  An effect of r329254
was that a copy-on-write fault actually entailed two page faults, not
one, even for single-threaded programs.  Now, in the expected case for
either single- or multithreaded programs, we are back to a single page
fault to complete a copy-on-write operation.  (In extremely rare
circumstances, a multithreaded program could suffer two page faults.)
