The redundant_metadata setting in ZFS allows users to trade resilience
for performance and space savings. This applies to all data and metadata
blocks in zfs, with one exception: gang blocks. Gang blocks currently
just take the copies property of the IO being ganged and, if it's 1,
sets it to 2. This means that we always make at least two copies of a
gang header, which is good for resilience. However, if the users care
more about performance than resilience, their gang blocks will be even
more of a penalty than usual.
We add logic to calculate the number of gang headers copies directly,
and store it as a separate IO property. This is stored in the IO
properties and not calculated when we decide to gang because by that
point we may not have easy access to the relevant information about what
kind of block is being stored. We also check the redundant_metadata
property when doing so, and use that to decide whether to store an extra
copy of the gang headers, compared to the underlying blocks.

Many tests use mktemp to create temporary files and dirs, which will
usually put them in /tmp unless instructed otherwise. This had led to
many tests trying to give mktemp a useful temp path in ad-hoc ways, and
others just using it directly without knowing they're potentially
leaving stuff lying around.
So we set TMPDIR to FILEDIR, which makes the simplest uses of mktemp put
things in the wanted work dir.
Included here is a hack to get TMPDIR into the test. If a test has to be
run as a different user (most of them), it is run through sudo. ld.so
from glibc will not pass TMPDIR to a setuid program, so instead we
re-set TMPDIR after sudo before running the target command.

The default outputdir had a timestamp appended in TestRun.__init__, and
then the timestamp was unconditionally applied again after the runfile
had been loaded, assuming that an outputdir would be set in the runfile
too. If the runfile didn't have an outputdir, then the outputdir would
get a second timestamp appended.
Further, if test groups or individual tests themselves specificed an
outputdir, those would be set on their config, but would not get a
timestamp appended. It's not entirely clear if that's wrong or not, but
it is certainly not consistent with the rest.
To clean all this up, change things to append a timestamp to a received
outputdir (from arg or runfile) before setting it in any TestRun,
TestGroup or Test object.

The actual ZTS scripts are simple drivers for the crypto_test program in
it's "correctness" mode. This mode takes a file full of test vectors
(inputs and expected outputs), runs them, and checks that the results
are expected. It will run the tests for each implementation of the
algorithm provided by the ICP.
The test vectors are taken from Project Wycheproof, which provides a
huge number of tests, including exercising many edge cases and common
implementation mistakes. These tests are provided are JSON files, so a
program is included here to convert them into a simpler line-based
format for crypto_test to consume.
crypto_test also has a "performance" mode, which will run simple
benchmarks against all implementations provded by the ICP and output
them for comparison. This is not used by ZTS, but is available to assist
with development of new implementations of the underlying primitives.

recv_fix_encryption_hierarchy() in its present state goes through all
stream filesystems, and for each one traverses the snapshots in order to
find one that exists locally. This happens by calling guid_to_name() for
each snapshot, which iterates through all children of the filesystem.
This results in CPU utilization of 100% for several minutes (for ~1000
filesystems on a Ryzen 4350G) for 1 thread at the end of a raw receive
(-w, regardless whether encrypted or not, dryrun or not).
Fix this by following a different logic: using the top_fs name, call
gather_nvlist() to gather the nvlists for all local filesystems. For
each one filesystem, go through the snapshots to find the corresponding
stream's filesystem (since we know the snapshots guid and can search
with it in stream_avl for the stream's fs). Then go on to fix the
encryption roots and locations as in its present state.
Avoiding guid_to_name() iteratively makes
recv_fix_encryption_hierarchy() significantly faster (from several
minutes to seconds for ~1000 filesystems on a Ryzen 4350G).
Another problem is the following: in case we have promoted a clone of
the filesystem outside the top filesystem specified in zfs send, zfs
receive does not fail but returns an error:
recv_incremental_replication() fails to find its origin and errors out
with needagain=1. This results in recv_fix_hierarchy() not being called
which may render some children of the top fs not mountable since their
encryption root was not updated. To circumvent this make
recv_incremental_replication() silently ignore this error.

Originally #16856 updated Linux Direct I/O requests to use the new
pin_user_pages API. However, it was an oversight that this PR only
handled iov_iter's of type ITER_IOVEC and ITER_UBUF. Other iov_iter
types may try and use the pin_user_pages API if it is available. This
can lead to panics as the iov_iter is not being iterated over correctly
in zfs_uio_pin_user_pages().
Unfortunately, generic iov_iter API's that call pin_user_page_fast() are
protected as GPL only. Rather than update zfs_uio_pin_user_pages() to
account for all iov_iter types, we can simply just call
zfs_uio_get_dio_page_iov_iter() if the iov_iter type is not ITER_IOVEC
or ITER_UBUF. zfs_uio_get_dio_page_iov_iter() calls the
iov_iter_get_pages() calls that can handle any iov_iter type.
In the future it might be worth using the exposed iov_iter iterator
functions that are included in the header iov_iter.h since v6.7. These
functions allow for any iov_iter type to be iterated over and advanced
while applying a step function during iteration. This could possibly be
leveraged in zfs_uio_pin_user_pages().
A new ZFS test case was added to test that a ITER_BVEC is handled
correctly using this new code path. This test case was provided though
issue #16956.
