Main part is that kern_copyin on amd64 after LA57 should query the top
of UVA for correct operations. In fact it should started doing that
after the workaround for AMD bug with IRET in the last user page was
fixed by reducing UVA by a page.
Also since we started calculating top of UVA, fix MIPS according to
the comment.

Messing with gnop devices under a zpool fails in this test, causing

Skip the test for now until the issue is resolved.

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.

This avoids injecting errors into the test system's mirrors.
gnop seems like a good solution here but it injects errors at the wrong
place vs where these tests expect and does not support a 'max global count'
like the failpoints do with 'n*' syntax.

Prior to this change a `SF_IMMUTABLE` chflagsat(2)'ed file (`path`) was left
behind, which sabotaged kyua(1) from being able to clean up the work directory,
This resulted in unnecessary work for folks having to clean up the work
directory on non-disposable systems, which defaults to `/tmp`. Use `UF_OFFLINE`
instead of `SF_IMMUTABLE`, in part because setting `SF_IMMUTABLE` isn't relevant
to the test and `SF_IMMUTABLE` cannot be cleared at all securelevels, as pointed
out by @asomers.
Additional work is required to catch cases like this upfront in the future to
avoid tester headache. See PR # 247765 for more details/followup.

Fix the netinet/netinet6 divert tests falsely reporting 'ipdivert module is

This patch fixes two issues relating to FUSE_ACCESS when the
default_permissions mount option is disabled:
* VOP_ACCESS() calls with VADMIN set should never be sent to a fuse server
in the form of FUSE_ACCESS operations. The FUSE protocol has no equivalent
of VADMIN, so we must evaluate such things kernel-side, regardless of the
default_permissions setting.
* The FUSE protocol only requires FUSE_ACCESS to be sent for two purposes:
for the access(2) syscall and to check directory permissions for
searchability during lookup. FreeBSD sends it much more frequently, due to
differences between our VFS and Linux's, for which FUSE was designed. But
this patch does eliminate several cases not required by the FUSE protocol:
* for any FUSE_*XATTR operation
* when creating a new file
* when deleting a file
* when setting timestamps, such as by utimensat(2).
* Additionally, when default_permissions is disabled, this patch removes one
FUSE_GETATTR operation when deleting a file.

When a FUSE operation other than LOOKUP returns ENOENT, the kernel will
reclaim that vnode, resuling in a FUSE_FORGET being sent a short while
later. Many of the ENOENT tests weren't expecting those FUSE_FORGET
operations. They usually passed by luck since FUSE_FORGET is often delayed.
This commit adds appropriate expectations.

common_init_tbl is only used within this single CU, so it should be marked
static.
WARNS=6 also complained about the var defined by
`ATF_TC_WITH_CLEANUP(getastats);` being unused, which turns out to be
because it's not been hooked up in ATF_TP_ADD_TCS. kp@ did not immediately
recall any reason for this, and the case passes on my local system, so hook
it up.
Note that I've not yet set WARNS= 6 here. Investigation is underway to see
if we can feasibly default WARNS to 6 for src builds to catch directories
too deep to inherit a WARNS from the top-level subdirectories' Makefile.inc.
Those particular WARNS settings will be subsequently removed as they become
redundant with a more-global default.

mac_bsdextended(4), when enabled, causes ordinary operations to send many
more VOP_GETATTRs to file system. The fusefs tests expectations aren't
written with those in mind. Optionally expecting them would greatly
obfuscate the fusefs tests. Worse, certain fusefs functionality (like
attribute caching) would be impossible to test if the tests couldn't expect
an exact number of GETATTR operations.
This commit resolves that conflict by making two changes:
1. The fusefs tests will now check for mac_bsdextended, and skip if it's
enabled.
2. The mac_bsdextended tests will now check whether the module is enabled, not
merely loaded. If it's loaded but disabled, the tests will automatically
enable it for the duration of the tests.
With these changes, a CI system can achieve best coverage by loading both
fusefs and mac_bsdextended at boot, and setting
security.mac.bsdextended.enabled=0
