Linux 6.10 compat: Fix tracepoints definitions
__string field definition includes the source variable for a value
of the string when the TP hits; in 6.10+ kernels, __assign_str()
uses that to copy a value from src to the string, with older
kernels, __assign_str still accepted src as a second parameter.

Adding Direct IO Support
Adding O_DIRECT support to ZFS to bypass the ARC for writes/reads.

O_DIRECT support in ZFS will always ensure there is coherency between
buffered and O_DIRECT IO requests. This ensures that all IO requests,
whether buffered or direct, will see the same file contents at all
times. Just as in other FS's , O_DIRECT does not imply O_SYNC. While
data is written directly to VDEV disks, metadata will not be synced
until the associated  TXG is synced.
For both O_DIRECT read and write request the offset and request sizes,
at a minimum, must be PAGE_SIZE aligned. In the event they are not,
then EINVAL is returned unless the direct property is set to always (see
below).

For O_DIRECT writes:
The request also must be block aligned (recordsize) or the write
request will take the normal (buffered) write path. In the event that
request is block aligned and a cached copy of the buffer in the ARC,
then it will be discarded from the ARC forcing all further reads to
retrieve the data from disk.

For O_DIRECT reads:
The only alignment restrictions are PAGE_SIZE alignment. In the event
that the requested data is in buffered (in the ARC) it will just be
copied from the ARC into the user buffer.

For both O_DIRECT writes and reads the O_DIRECT flag will be ignored in
the event that file contents are mmap'ed. In this case, all requests
that are at least PAGE_SIZE aligned will just fall back to the buffered
paths. If the request however is not PAGE_SIZE aligned, EINVAL will
be returned as always regardless if the file's contents are mmap'ed.

Since O_DIRECT writes go through the normal ZIO pipeline, the
following operations are supported just as with normal buffered writes:
Checksum
Compression
Encryption
Erasure Coding
There is one caveat for the data integrity of O_DIRECT writes that is
distinct for each of the OS's supported by ZFS.
FreeBSD - FreeBSD is able to place user pages under write protection so
          any data in the user buffers and written directly down to the
	  VDEV disks is guaranteed to not change. There is no concern
	  with data integrity and O_DIRECT writes.
Linux - Linux is not able to place anonymous user pages under write
        protection. Because of this, if the user decides to manipulate
	the page contents while the write operation is occurring, data
	integrity can not be guaranteed. However, there is a module
	parameter `zfs_vdev_direct_write_verify` that controls the
	if a O_DIRECT writes that can occur to a top-level VDEV before
	a checksum verify is run before the contents of the I/O buffer
        are committed to disk. In the event of a checksum verification
	failure the write will return EIO. The number of O_DIRECT write
	checksum verification errors can be observed by doing
	`zpool status -d`, which will list all verification errors that
	have occurred on a top-level VDEV. Along with `zpool status`, a
	ZED event will be issues as `dio_verify` when a checksum
	verification error occurs.

ZVOLs and dedup is not currently supported with Direct I/O.

A new dataset property `direct` has been added with the following 3
allowable values:
disabled - Accepts O_DIRECT flag, but silently ignores it and treats
	   the request as a buffered IO request.
standard - Follows the alignment restrictions  outlined above for
	   write/read IO requests when the O_DIRECT flag is used.
always   - Treats every write/read IO request as though it passed
           O_DIRECT and will do O_DIRECT if the alignment restrictions
	   are met otherwise will redirect through the ARC. This
	   property will not allow a request to fail.

There is also a module parameter zfs_dio_enabled that can be used to
force all reads and writes through the ARC. By setting this module
parameter to 0, it mimics as if the  direct dataset property is set to
disabled.

Along the way, the blk_queue_set_write_cache() compat wrapper gets a

single bool. Also the very very ancient version that sets q->flush_flags
directly couldn't actually turn it off, so I've fixed that. Not that we

b409892ae5 Linux 6.10: rework queue limits setup
Linux has started moving to a model where instead of applying block
queue limits through individual modification functions, a complete
limits structure is built up and applied atomically, either when the
block device or open, or some time afterwards. As of 6.10 this
transition appears only partly completed.

This commit matches that model within OpenZFS in a way that should work
for past and future kernels. We set up a queue limits structure with any
limits that have had their modification functions removed. For newer
kernels that can have limits applied at block device open
(HAVE_BLK_ALLOC_DISK_2ARG), we have a conversion function to turn the
OpenZFS queue limits structure into Linux's queue_limits structure,
which can then be passed in. For older kernels, we provide an
application function that just calls the old functions for each limit in
the structure.

7ac00d3c26 find_system_library: fix var cleanup when library not found
The "not found" path is attempting to clear SOMELIB_CFLAGS and
SOMELIB_LIBS by resetting them in AC_SUBST(). However, the second arg to
AC_SUBST is expanded in autoconf with `m4_ifvaln([$2], [[$1]=$2])`,
which is defined as "if the first arg is non-empty". The m4 "empty"
construction is [], therefore, the existing AC_SUBST calls never modify
the variables at all.

The effect of this is that leftovers from the library test can leak out.
At least, if a library header is found in the first stage, but the
library itself is not, -lsomelib is added to SOMELIB_LIBS and further
tests done. If that library is not found, SOMELIB_LIBS will not be
cleared.

For most of our library tests this hasn't been a problem, as they're
either always found properly via pkg-config or set directly, or the
calling test immediately aborts configure. For an optional dependency
however, an apparent "partial" result where the header is found but no
corresponding library causes link errors later.

I think a complete fix should probably not be setting SOMELIB_xxx until
the final result is known, but for now, adjusting the AC_SUBST calls to
explictly set the empty shell string (which is not "empty" to m4) at
least restores the intent.

Restrict the substitution in the Makefile to the dedicated list.

This construct is inspired by Mo Zhou's detection of the execution
shell and follows the strategy of Peter in 6ef28c526b.

As of 2024, the initscripts are mostly relevant on Debian, Gentoo and

vdev_disk: ensure trim errors are returned immediately
After 06e25f9c4, the discard issuing code was organised such that if
requesting an async discard or secure erase failed before the IO was
issued (that is, calling __blkdev_issue_discard() returned an error),
the failed zio would never be executed, resulting in txg_sync hanging
forever waiting for IO to finish.

This commit fixes that by immediately executing a failed zio on error.
To handle the successful synchronous op case, we fake an async op by,
when not using an asynchronous submission method, queuing the successful
result zio as part of the discard handler.

Since it was hard to understand the differences between discard and
secure erase, and sync and async, across different kernel versions, I've
commented and reorganised the code a bit to try and make everything more
contained and linear.

zvol_os: fix compile with blk-mq on Linux 4.x
99741bde5 accesses a cached blk-mq hardware context through the mq_hctx
field of struct request. However, this field did not exist until 5.0.
Before that, the private function blk_mq_map_queue() was used to dig it
out of broader queue context. This commit detects this situation, and
handles it with a poor-man's simulation of that function.

c00c085bfb config: use -Wno-format-truncation globally
-Wformat-truncation looks for places where the return code of snprintf()
is unchecked and the provided buffer might be too short. This is based
on a heuristic that can change between compiler versions.

It has been seen to get this wrong in ddt_object_name(), leading to
DDT_NAMELEN being increased somewhat arbitrarily.

There's no good reason to have this warning enabled, so here we disable
it everywhere. Truncation may be undesirable, but snprintf() is
guaranteed to emit a trailing null, so at worst we get a short string,
not a buffer overrun.

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.

Since Linux 6.2, the implementation of flush_dcache_page on riscv

This patch uses existing mechanism to override flush_dcache_page,

it is only used to do some check against HugeTLB pages, which only
exist in userspace. ZFS uses flush_dcache_page only on kernel pages,
thus this patch will not introduce any behaviour change.

e69ade32e1 contrib: bash_completion.d: make install destination vendor dependent
Certain Linux distributions (Debian/Ubuntu at least) expect
bash-completion snippets to be installed in
/usr/share/bash-completion/completions instead of
/etc/bash_completion.d.

This patch sets the bashcompletiondir variable based on the vendor,
inspired by similar settings for initdir and initconfdir.

It seems that commit 612b8dff5b
caused the file to be installed in the first-place (thus the error
when building debian packages only became apparent when testing a
2.2.0-rc4 build)

The change only sets the variable in Makefile context - the
rpm/zfs.spec.in file has the path hardcoded as
%{_sysconfdir}/bash_completion.d/zfs, but since running
```
./configure --sysconfdir=/myetc  ; make rpm
```
also results in all relevant files to be installed in /etc instead of
/myetc I assume this can remain as is.

In Linux commit 13bc24457850583a2e7203ded05b7209ab4bc5ef, direct access
to the i_ctime member of struct inode was removed. The new approach is
to use accessor methods that exclusively handle passing the timestamp
around by value. This change adds new tests for each of these functions
and introduces zpl_* equivalents in include/os/linux/zfs/sys/zpl.h. In
where the inode_get/set_ctime*() functions exist, these zpl_* calls will
be mapped to the new functions. On older kernels, these macros just wrap
direct-access calls. The code that operated on an address of ip->i_ctime
to call ZFS_TIME_DECODE() now will take a local copy using
zpl_inode_get_ctime(), and then pass the address of the local copy when
performing the ZFS_TIME_DECODE() call, in all cases, rather than
directly accessing the member.

Linux 6.5 compat: blkdev changes
Multiple changes to the blkdev API were introduced in Linux 6.5. This
includes passing (void* holder) to blkdev_put, adding a new
blk_holder_ops* arg to blkdev_get_by_path, adding a new blk_mode_t type
that replaces uses of fmode_t, and removing an argument from the release
handler on block_device_operations that we weren't using. The open
function definition has also changed to take gendisk* and blk_mode_t, so
update it accordingly, too.

Implement local wrappers for blkdev_get_by_path() and
vdev_blkdev_put() so that the in-line calls are cleaner, and place the
conditionally-compiled implementation details inside of both of these
local wrappers. Both calls are exclusively used within vdev_disk.c, at
this time.

Add blk_mode_is_open_write() to test FMODE_WRITE / BLK_OPEN_WRITE
The wrapper function is now used for testing using the appropriate
method for the kernel, whether the open mode is writable or not.

Emphasize fmode_t arg in zvol_release is not used

Linux 6.5 compat: register_sysctl_table removed
Additionally, the .child element of ctl_table has been removed in 6.5.
This change adds a new test for the pre-6.5 register_sysctl_table()
function, and uses the old code in that case. If it isn't found, then
the parentage entries in the tables are removed, and the register_sysctl
call is provided the paths of "kernel/spl", "kernel/spl/kmem", and
"kernel/spl/kstat" directly, to populate each subdirectory over three
calls, as is the new API.

shellcheck: disable "unreachable command" check [SC2317]
This new check in 0.9.0 appears to have some issues with various forms
of "early return", like trap, exit and return. This is tripping up (at
least):

  cmd/zed/zed.d/history_event-zfs-list-cacher.sh
  /etc/zfs/zfs-functions

Its not obvious what its complaining about or what the remedy is, so it
seems sensible to disable this check for now.

Workaround for Linux PowerPC GPL-only cpu_has_feature()
Linux since 4.7 makes interface 'cpu_has_feature' to use jump labels on
powerpc if CONFIG_JUMP_LABEL_FEATURE_CHECKS is enabled, in this case
however the inline function references GPL-only symbol
'cpu_feature_keys'.

ZFS currently uses 'cpu_has_feature' either directly or indirectly from
several places; while it is unknown how this issue didn't break ZFS on
64-bit little-endian powerpc, it is known to break ZFS with many Linux
versions on both 32-bit and 64-bit big-endian powerpc.

Until this issue is fixed in Linux, we have to workaround it by
overriding affected inline functions without depending on
'cpu_feature_keys'.

556ed09537 Introduce ZFS_LINUX_REQUIRE_API autoconf macro
Currently, if API tests fail, we either ignore the failures, or
unconditionally halt the kernel build.  This leads to situations where
incompatibilities with existing APIs may develop, but not trip the
configure compatibility checks.

This introduces a new mechanism to require APIs for kernels above a
particular version.  While not perfect, this at least guarantees
mainline kernels do not break existing APIs without at least providing
some warning.

targets for make to build native debian packages. Github workflows
are updated to build and test native Debian packages.

Native packages only build with pre-configured paths (see the
dh_auto_configure section in contrib/debian/rules.in). While
building native packages, paths should not be configured. Initial
config flags e.g. '--enable-debug' are replaced in
contrib/debian/rules.in.

Additional packages on top of existing zfs packages required to
build native packages include debhelper-compat, dh-python, dkms,
po-debconf, python3-all-dev, python3-sphinx.
