* Remove zpool_create_013_neg. FreeBSD doesn't have an equivalent of
Solaris's metadevices. GEOM would be the equivalent, but since all geoms
are the same from ZFS's perspective, this test would be redundant with
zpool_create_012_neg
* Remove zpool_create_014_neg. FreeBSD does not support swapping to regular
files.
* Remove zpool_create_016_pos. This test is redundant with literally every
other test that creates a disk-backed pool.
* s:/etc/vfstab:/etc/fstab in zpool_create_011_neg
* Delete the VTOC-related portion of zpool_create_008_pos. FreeBSD doesn't
use VTOC.
* Replace dumpadm with dumpon and swap with swapon in multiple tests.
* In zpool_create_015_neg, don't require "zpool create -n" to fail. It's
reasonable for that variant to succeed, because it doesn't actually open
the zvol.
* Greatly simplify zpool_create_012_neg. Make it safer, too, but not
interfering with the system's regular swap devices.
* Expect zpool_create_011_neg to fail (PR 241070)
* Delete some redundant cleanup steps in various tests
* Remove some unneeeded ATF timeout specifications. The default is fine.

CTLFLAG_STATS identifies a sysctl OID as statistical or informational,
as opposed to a configurable/tunable OID that changes behavior.
This can be used, for example, to verfiy that the kyua tests do not
modify configurable OIDs when allow_sysctl_side_effects is true.
Add CTLFLAG_STATS to all COUNTER_U64* OIDs.
I will add the flag to more OIDs in a few subsequent commits, to
facilitate MFC. The flag should be added to many more OIDs. I plan to
add it those that my test found and some nearby that looked obvious.

nvdimm_e820 is a newbus pseudo driver that looks for "legacy" e820 PRAM
spans and creates ordinary-looking SPA devfs nodes for them
(/dev/nvdimm_spaN).
As these legacy regions lack real NFIT SPA regions and namespace
definitions, they must be administratively sliced up externally using
device.hints. This is similar in purpose to the Linux memmap= mechanism.
It is assumed that systems with working NFIT tables will not have any use
for this driver, and that that will be the prevailing style going forward,
so if there are no explicit hints provided, this driver does not
automatically create any devices.

Realistically, this cannot work. We don't allow the tun to be opened twice,
so it must be done via fd passing, fork, dup, some mechanism like these.
Applications demonstrably do not enforce strict ordering when they're
handing off tun devices, so the parent closing before the child will easily
leave the tun/tap device in a bad state where it can't be destroyed and a
confused user because they did nothing wrong.
Concede that we can't leave the tun/tap device in this kind of state because
of software not playing the TUNSIFPID game, but it is still good to find and
fix this kind of thing to keep ifconfig(8) up-to-date and help ensure good
discipline in tun handling.

Interested users can blacklist any/all of these with certctl(8), examples:
- mv /usr/share/certs/trusted/... /usr/share/certs/blacklisted/...; \
certctl rehash
- certctl blacklist /usr/share/certs/trusted/*; \
certctl rehash
Certs can be easily examined after installation with `certctl list`, and
certctl blacklist will accept the hashed filename as output by list or as
seen in /etc/ssl/certs
No objection from: secteam
Relnotes: Definite maybe
It seems reasonable to allow, for instance:
$ certctl list
# reviews output -- ah, yeah, I don't trust that one
$ certctl blacklist ce5e74ef.0
$ certctl rehash
We can unambiguously determine what cert "ce5e74ef.0" refers to, and we've
described it to them in `certctl list` output -- I see little sense in
forcing another level of filesystem inspection to determien what cert file
this physically corresponds to.
During readdir() we guarantee that the tn_dir.tn_parent does not go
away, but it might be replaced by a parallel rename. Read tn_parent
only once, then use the cached value.

Currently, if you do:
$ ifconfig tun0 create
$ ifconfig tun0 name wg0
$ ls -l /dev | egrep 'wg|tun'
You will see tun0, but no wg0. In fact, it's slightly more annoying to make
the association between the new name and the old name in order to open the
device (if it hadn't been opened during the rename).
Register an eventhandler for ifnet_arrival_events and catch interface
renames. We can determine if the ifnet is a tun easily enough from the
if_dname, which matches the cevsw.d_name from the associated tuntap_driver.
Some locking dance is required because renames don't require the device to
be opened, so it could go away in the middle of handling the ioctl, but as
soon as we've verified this isn't the case we can attempt to busy the tun
and either bail out if the tun device is dying, or we can proceed with the
rename.
We only create these aliases on a best-effort basis. Renaming a tun device
to "usbctl", which doesn't exist as an ifnet but does as a /dev, is clearly
not that disastrous, but we can't and won't create a /dev for that.
A future commit will create device aliases when a tuntap device is renamed
so that it's still easily found in /dev after the rename. Said mechanism
will want to keep the tun alive long enough to either realize that it's
about to go away or complete the alias creation, even if the alias is about
to get destroyed.
While we're introducing it, using it to prevent open devices from going away
makes plenty of sense and keeps the logic on waking up tun_destroy clean, so
we don't have multiple places trying to cv_broadcast unless it's still in
use elsewhere.
Four drivers (hpt27xx, hptmv, hptnr, hptrr, hpt27xx) include precompiled
binary objects; have users load them as modules if they are needed.
Additional work (i.e., integrating devmatch) required before MFC.

This change allows to specify a watchdog(9) timeout for a system
shutdown. The timeout is activated when the watchdogd daemon is
stopped. The idea is to a prevent any indefinite hang during late
stages of the shutdown. The feature is implemented in rc.d/watchdogd,
it builds upon watchdogd -x option.
Note that the shutdown timeout is not actiavted when the watchdogd
service is individually stopped by an operator. It is also not
activated for the 'shutdown' to the single-user mode. In those cases it
is assumed that the operator knows what they are doing and they have
means to recover the system should it hang.
Significant subchanges and implementation details:
- the argument to rc.shutdown, completely unused before, is assigned to
rc_shutdown variable that can be inspected by rc scripts
- init(8) passes "single" or "reboot" as the argument, this is not
changed
- the argument is not mandatory and if it is not set then rc_shutdown is
set to "unspecified"
- however, the default jail management scripts and jail configuration
examples have been updated to pass "jail" to rc.shutdown, just in case
- the new timeout can be set via watchdogd_shutdown_timeout rc option
- for consistency, the regular timeout can now be set via
watchdogd_timeout rc option
- watchdogd_shutdown_timeout and watchdogd_timeout override timeout
specifications in watchdogd_flags
- existing configurations, where the new rc options are not set, should
keep working as before
I am not particularly wed to any of the implementation specifics.
I am open to changing or removing any of them as long as the provided
functionality is the same (or very close) to the proposed one.
For example, I think it can be implemented without using watchdogd -x,
by means of watchdog(1) alone. In that case there would be a small
window between stopping watchdogd and running watchdog, but I think that
that is acceptable.

The feature is implemented as an extension of the existing
ZFS_IOC_RENAME ioctl. Both the userland and the DSL interfaces support
renaming only a single bookmark at a time. As of now, there is no ZCP
interface to the new functionality. I am going to add it once the DSL
interface passes a test of time.
This change picks up support for zfs_ioc_namecheck_t::ENTITY_NAME that
was added to ZoL as part of Redacted Send/Receive feature by Paul
Dagnelie <pcd@delphix.com>. This is needed to allow a bookmark name in
zc_name.
