51c2bd0def vdev_disk: rewrite BIO filling machinery to avoid split pages
This commit tackles a number of issues in the way BIOs (`struct bio`)
are constructed for submission to the Linux block layer.

The kernel has a hard upper limit on the number of pages/segments that
can be added to a BIO, as well as a separate limit for each device
(related to its queue depth and other scheduling characteristics).

ZFS counts the number of memory pages in the request ABD
(`abd_nr_pages_off()`, and then uses that as the number of segments to
put into the BIO, up to the hard upper limit. If it requires more than
the limit, it will create multiple BIOs.

Leaving aside the fact that page count method is wrong (see below), not
limiting to the device segment max means that the device driver will
need to split the BIO in half. This is alone is not necessarily a
problem, but it interacts with another issue to cause a much larger
problem.

The kernel function to add a segment to a BIO (`bio_add_page()`) takes a
`struct page` pointer, and offset+len within it. `struct page` can
represent a run of contiguous memory pages (known as a "compound page").
In can be of arbitrary length.

The ZFS functions that count ABD pages and load them into the BIO
(`abd_nr_pages_off()`, `bio_map()` and `abd_bio_map_off()`) will never
consider a page to be more than `PAGE_SIZE` (4K), even if the `struct
page` is for multiple pages. In this case, it will load the same `struct
page` into the BIO multiple times, with the offset adjusted each time.

With a sufficiently large ABD, this can easily lead to the BIO being
entirely filled much earlier than it could have been. This is also
further contributes to the problem caused by the incorrect segment limit
calculation, as its much easier to go past the device limit, and so
require a split.

Again, this is not a problem on its own.

The logic for "never submit more than `PAGE_SIZE`" is actually a little
more subtle. It will actually never submit a buffer that crosses a 4K
page boundary.

In practice, this is fine, as most ABDs are scattered, that is a list of
complete 4K pages, and so are loaded in as such.

Linear ABDs are typically allocated from slabs, and for small sizes they
are frequently not aligned to page boundaries. For example, a 12K
allocation can span four pages, eg:

     -- 4K -- -- 4K -- -- 4K -- -- 4K --
    |        |        |        |        |
          :## ######## ######## ######:    [1K, 4K, 4K, 3K]

Such an allocation would be loaded into a BIO as you see:

    [1K, 4K, 4K, 3K]

This tends not to be a problem in practice, because even if the BIO were
filled and needed to be split, each half would still have either a start
or end aligned to the logical block size of the device (assuming 4K at
least).

---

In ideal circumstances, these shortcomings don't cause any particular
problems. Its when they start to interact with other ZFS features that
things get interesting.

Aggregation will create a "gang" ABD, which is simply a list of other
ABDs. Iterating over a gang ABD is just iterating over each ABD within
it in turn.

Because the segments are simply loaded in order, we can end up with
uneven segments either side of the "gap" between the two ABDs. For
example, two 12K ABDs might be aggregated and then loaded as:

    [1K, 4K, 4K, 3K, 2K, 4K, 4K, 2K]

Should a split occur, each individual BIO can end up either having an
start or end offset that is not aligned to the logical block size, which
some drivers (eg SCSI) will reject. However, this tends not to happen
because the default aggregation limit usually keeps the BIO small enough
to not require more than one split, and most pages are actually full 4K
pages, so hitting an uneven gap is very rare anyway.

If the pool is under particular memory pressure, then an IO can be
broken down into a "gang block", a 512-byte block composed of a header
and up to three block pointers. Each points to a fragment of the
original write, or in turn, another gang block, breaking the original
data up over and over until space can be found in the pool for each of
them.

Each gang header is a separate 512-byte memory allocation from a slab,
that needs to be written down to disk. When the gang header is added to
the BIO, its a single 512-byte segment.

Pulling all this together, consider a large aggregated write of gang
blocks. This results a BIO containing lots of 512-byte segments. Given
our tendency to overfill the BIO, a split is likely, and most possible
split points will yield a pair of BIOs that are misaligned. Drivers that
care, like the SCSI driver, will reject them.

---

This commit is a substantial refactor and rewrite of much of `vdev_disk`
to sort all this out.

`vdev_bio_max_segs()` now returns the ideal maximum size for the device,
if available. There's also a tuneable `zfs_vdev_disk_max_segs` to
override this, to assist with testing.

We scan the ABD up front to count the number of pages within it, and to
confirm that if we submitted all those pages to one or more BIOs, it
could be split at any point with creating a misaligned BIO.  If the
pages in the BIO are not usable (as in any of the above situations), the
ABD is linearised, and then checked again. This is the same technique
used in `vdev_geom` on FreeBSD, adjusted for Linux's variable page size
and allocator quirks.

`vbio_t` is a cleanup and enhancement of the old `dio_request_t`. The
idea is simply that it can hold all the state needed to create, submit
and return multiple BIOs, including all the refcounts, the ABD copy if
it was needed, and so on. Apart from what I hope is a clearer interface,
the major difference is that because we know how many BIOs we'll need up
front, we don't need the old overflow logic that would grow the BIO
array, throw away all the old work and restart. We can get it right from
the start.

52a2af6fd1 abd: add page iterator
The regular ABD iterators yield data buffers, so they have to map and
unmap pages into kernel memory. If the caller only wants to count
chunks, or can use page pointers directly, then the map/unmap is just
unnecessary overhead.

This adds adb_iterate_page_func, which yields unmapped struct page
instead.

c0c4866f8a dmu: Allow buffer fills to fail
When ZFS overwrites a whole block, it does not bother to read the
old content from disk. It is a good optimization, but if the buffer
fill fails due to page fault or something else, the buffer ends up
corrupted, neither keeping old content, nor getting the new one.

On FreeBSD this is additionally complicated by page faults being
blocked by VFS layer, always returning EFAULT on attempt to write
from mmap()'ed but not yet cached address range.  Normally it is
not a big problem, since after original failure VFS will retry the
write after reading the required data.  The problem becomes worse
in specific case when somebody tries to write into a file its own
mmap()'ed content from the same location.  In that situation the
only copy of the data is getting corrupted on the page fault and
the following retries only fixate the status quo.  Block cloning
makes this issue easier to reproduce, since it does not read the
old data, unlike traditional file copy, that may work by chance.

This patch provides the fill status to dmu_buf_fill_done(), that
in case of error can destroy the corrupted buffer as if no write
happened.  One more complication in case of block cloning is that
if error is possible during fill, dmu_buf_will_fill() must read
the data via fall-back to dmu_buf_will_dirty().  It is required
to allow in case of error restoring the buffer to a state after
the cloning, not not before it, that would happen if we just call
dbuf_undirty().

d22bf6a9bd LUA: Backport CVE-2020-24370's patch
CVE-2020-24370 is a security vulnerability in lua. Although the CVE
description in CVE-2020-24370 said that this CVE only affected lua
5.4.0, according to lua this CVE actually existed since lua 5.2. The
root cause of this CVE is the negation overflow that occurs when you
try to take the negative of 0x80000000. Thus, this CVE also exists in
openzfs. Try to backport the fix to the lua in openzfs since the
original fix is for 5.4 and several functions have been changed.

00d85a98ea BRT: Fix FICLONE/FICLONERANGE shortened copy
On Linux the ioctl_ficlonerange() and ioctl_ficlone() system calls
are expected to either fully clone the specified range or return an
error.  The range may be for an entire file.  While internally ZFS
supports cloning partial ranges there's no way to return the length
cloned to the caller so we need to make this all or nothing.

As part of this change support for the REMAP_FILE_CAN_SHORTEN flag
has been added.  When REMAP_FILE_CAN_SHORTEN is set zfs_clone_range()
will return a shortened range when encountering pending dirty records.
When it's clear zfs_clone_range() will block and wait for the records
to be written out allowing the blocks to be cloned.

Furthermore, the file range lock is held over the region being cloned
to prevent it from being modified while cloning.  This doesn't quite
provide an atomic semantics since if an error is encountered only a
portion of the range may be cloned.  This will be converted to an
error if REMAP_FILE_CAN_SHORTEN was not provided and returned to the
caller.  However, the destination file range is left in an undefined
state.

A test case has been added which exercises this functionality by
verifying that `cp --reflink=never|auto|always` works correctly.

    zpool online --power <pool> <device>     Turn on device slot power
    zpool clear --power <pool> [device]      Turn on device slot power

If the ZPOOL_AUTO_POWER_ON_SLOT env var is set, then the '--power'
option is automatically implied for `zpool online` and `zpool clear`
and does not need to be passed.

zpool status also gets a --power option to print the slot power status.

59112ca27d zed: misc vdev_enc_sysfs_path fixes
There have been rare cases where the VDEV_ENC_SYSFS_PATH value that zed
gets passed is stale.  To mitigate this, dynamically check the sysfs
path at the time of zed event processing, and use the dynamic value if
possible.  Note that there will be other times when we can not
dynamically detect the sysfs path (like if a disk disappears) and have
to rely on the old value for things like turning on the fault LED.  That
is to say, we can't just blindly use the dynamic path in every case.

Also:
	- Add enclosure sysfs entry when running 'zpool add'
	- Fix 'slot' and 'enc' zpool.d scripts for nvme

ab653603f8 Don't assert mg_initialized due to device addition race
During device removal stress tests, we noticed that we were tripping 
the assertion that mg_initialized was true. After investigation, it was 
determined that the mg in question was the embedded log metaslab 
group for a newly added vdev; the normal mg had been initialized (by 
metaslab_sync_reassess, via vdev_sync_done). However, because the spa 
config alloc lock is not held as writer across both calls to 
metaslab_sync_reassess, it is possible for an allocation to happen 
between the two metaslab_groups being initialized. Because the metaslab 
code doesn't check the group in question, just the vdev's main mg, it 
is possible to get past the initial check in vdev_allocatable and 
later fail due to the assertion.

We simply remove the assertions. We could also consider locking the 
ALLOC lock around the reassess calls in vdev_sync_done, but that risks 
deadlocks. We could check the actual target mg in vdev_allocatable, 
but that risks racing with a passivation that comes in after that 
check but before the assertion. We still won't be able to actually 
allocate from the metaslab group if no metaslabs are ready, so this 
change shouldn't break anything.

9da745f5de Switch to CodeQL to detect prohibited function use
The LLVM/Clang developers pointed out that using the CPP to detect use
of functions that our QA policies prohibit risks invoking undefined
behavior. To resolve this, we configure CodeQL to detect forbidden
function usage.

Note that cpp in the context of CodeQL refers to C/C++, rather than the
C PreProcessor, which C++ also uses. It really should have been written
cxx, but that ship sailed a long time ago. This misuse of the term cpp
is retained in the CodeQL configuration for consistency with upstream
CodeQL.

As a side benefit, verbose make no longer is a wall of text showing a
bunch of CPP macros, which can make debugging slightly easier.

When spare or l2cache (aux) vdev is added during pool creation,
spa->spa_uberblock is not dumped until that point. Subsequently,
the aux label is never synchronized after its initial creation,
resulting in the uberblock label remaining undumped. The uberblock
is crucial for lib_blkid in identifying the ZFS partition type. To
address this issue, we now ensure sync of the uberblock label once
if it's not dumped initially.

2006ac1f4a Fix "out of memory" error
Drop the no_memory() call from zpool_in_use() when reading the
label fails and instead return the error to the caller.  This
prevents a misleading "internal error: out of memory" error
when the label can't be read.  This will result in is_spare()
returning B_FALSE instead of aborting, which is already safely
handled.

Furthermore, on Linux it's possible for EREMOTEIO to returned
by an NVMe device if the device has been low-level formatted
and not rescanned.  In this case we want to fallback to the
legacy scanning method and read any of the labels we can.

509526ad21 fix: preserve linux kmod signature in zfs-kmod rpm spec
This change provides rpm spec macros to sign the zfs and spl kmods as
the final step after the %install scriptlet. This is needed since the
find-debuginfo.sh script strips out debug symbols plus signatures.

Kernel module signing only occurs when the required files are present
as typically required in the Linux source tree:
- certs/signing_key.pem
- certs/signing_key.x509

The method for overriding the default __spec_install_post macro is
inspired by (and largely copied from) the Fedora kernel.spec.
