Add a selftest that tries to trigger a situation where two timer callbacks
are attempting to cancel each other's timer. By running them continuously,
we hit a condition where both run in parallel and cancel each other.
Without the fix in the previous patch, this would cause a lockup as
hrtimer_cancel on either side will wait for forward progress from the
callback.
Ensure that this situation leads to a EDEADLK error.

io_uring can asynchronously add a task_work while the task is getting
freezed. TIF_NOTIFY_SIGNAL will prevent the task from sleeping in
do_freezer_trap(), and since the get_signal()'s relock loop doesn't
retry task_work, the task will spin there not being able to sleep
until the freezing is cancelled / the task is killed / etc.
Run task_works in the freezer path. Keep the patch small and simple
so it can be easily back ported, but we might need to do some cleaning
after and look if there are other places with similar problems.

If io-wq worker creation fails, we retry it by queueing up a task_work.
tasK_work is needed because it should be done from the user process
context. The problem is that retries are not limited, and if queueing a
task_work is the reason for the failure, we might get into an infinite
loop.
It doesn't seem to happen now but it would with the following patch
executing task_work in the freezer's loop. For now, arbitrarily limit the
number of attempts to create a worker.

This commit removes the "pmf.rst" document, which was associated with
the PMF driver that enabled system state updates based on TA output
actions.
The driver now uses existing input events (KEY_SCREENLOCK, KEY_SLEEP,
and KEY_SUSPEND) instead of defining new udev rules in the
"/etc/udev/rules.d/" directory. Consequently, the pmf.rst document is no
longer necessary. Therefore, the pmf.rst documentation is being removed.

At present, the PMF driver employs custom system state codes to update
system states. It is recommended to replace these with existing input

The of_device_unregister call in therm_windtunnel's module_exit procedure
does not fully reverse the effects of of_platform_device_create in the
module_init prodedure. Once you unload this module, it is impossible
to load it ever again since only the first of_platform_device_create
call on the fan node succeeds.
This driver predates first git commit, and it turns out back then
of_platform_device_create worked differently than it does today.
So this is actually an old regression.
The appropriate function to undo of_platform_device_create now appears
to be of_platform_device_destroy, and switching to use this makes it
possible to unload and load the module as expected.

cpu_has_feature()/mmu_has_feature() are only able to check a single
feature at a time, but there is no enforcement of that.
In fact, as fixed in the previous commit, there was code that was
passing multiple values to cpu_has_feature().
So add a check that only a single feature is passed using popcount.
Note that the test allows 0 or 1 bits to be set, because some code
relies on cpu_has_feature(0) being false, the check with
CPU_FTRS_POSSIBLE ensures that. See for example CPU_FTR_PPC_LE.

In the xmon disassembly code there are several CPU feature checks to
determine what dialects should be passed to the disassembler. The
dialect controls which instructions the disassembler will recognise.
Unfortunately the checks are incorrect, because instead of passing a
single CPU feature they are passing a mask of feature bits.
For example the code:
if (cpu_has_feature(CPU_FTRS_POWER5))
dialect |= PPC_OPCODE_POWER5;
Is trying to check if the system is running on a Power5 CPU. But
CPU_FTRS_POWER5 is a mask of *all* the feature bits that are enabled on
a Power5.
In practice the test will always return true for any 64-bit CPU, because
at least one bit in the mask will be present in the CPU_FTRS_ALWAYS
mask.
Similarly for all the other checks against CPU_FTRS_xx masks.
Rather than trying to match the disassembly behaviour exactly to the
current CPU, just differentiate between 32-bit and 64-bit, and Altivec,
VSX and HTM.
That will cause some instructions to be shown in disassembly even
on a CPU that doesn't support them, but that's OK, objdump -d output
has the same behaviour, and if anything it's less confusing than some
instructions not being disassembled.

The CPU/MMU feature code has build-time checks that the feature value is
a builtin constant.
Back when the code was added clang wasn't able to compile the
checks, so an ifdef was added to avoid the checks for clang builds.
See commit b5fa0f7f88ed ("powerpc: Fix build failure with clang due
to BUILD_BUG_ON()")
These days clang 13 and later are able to build the checks successfully,
so drop the workaround.

LZ4 always reuses the decompressed buffer as its LZ77 sliding window
(dynamic dictionary) for optimal performance. However, in specific
cases, the output buffer may not fully contain valid page cache pages,
resulting in the use of short-lived pages for temporary purposes.
Due to the limited sliding window size, LZ4 shortlived bounce pages can
also be reused in a sliding manner, so each bounce page can be vmapped
multiple times in different relative positions by design. In order to
avoiding double frees, currently, reuse counts are recorded via page
refcount, but it will no longer be used as-is in the future world of
Memdescs.
Just maintain a lookup table to check if a shortlived page is reused.

The syzbot constructs a directory that has no dirblock but is non-inline,
i.e. the first directory block is a hole. And no errors are reported when
creating files in this directory in the following flow.
ext4_mknod
...
ext4_add_entry
// Read block 0
ext4_read_dirblock(dir, block, DIRENT)
bh = ext4_bread(NULL, inode, block, 0)
if (!bh && (type == INDEX || type == DIRENT_HTREE))
// The first directory block is a hole
// But type == DIRENT, so no error is reported.
After that, we get a directory block without '.' and '..' but with a valid
dentry. This may cause some code that relies on dot or dotdot (such as
make_indexed_dir()) to crash.
Therefore when ext4_read_dirblock() finds that the first directory block
is a hole report that the filesystem is corrupted and return an error to
avoid loading corrupted data from disk causing something bad.

ext4_rename2+0x26e5/0x4370 fs/ext4/namei.c:4214
[...]
============================================
The immediate cause of this problem is that there is only one valid dentry
for the block to be split during do_split, so split==0 results in out of
bounds accesses to the map triggering the issue.
do_split
unsigned split
dx_make_map
count = 1
split = count/2 = 0;
continued = hash2 == map[split - 1].hash;
---> map[4294967295]
The maximum length of a filename is 255 and the minimum block size is 1024,
so it is always guaranteed that the number of entries is greater than or
equal to 2 when do_split() is called.
But syzbot's crafted image has no dot and dotdot in dir, and the dentry
distribution in dirblock is as follows:
bus dentry1 hole dentry2 free
|xx--|xx-------------|...............|xx-------------|...............|
0 12 (8+248)=256 268 256 524 (8+256)=264 788 236 1024
So when renaming dentry1 increases its name_len length by 1, neither hole
nor free is sufficient to hold the new dentry, and make_indexed_dir() is
called.
In make_indexed_dir() it is assumed that the first two entries of the
dirblock must be dot and dotdot, so bus and dentry1 are left in dx_root
because they are treated as dot and dotdot, and only dentry2 is moved
to the new leaf block. That's why count is equal to 1.
Therefore add the ext4_check_dx_root() helper function to add more sanity
checks to dot and dotdot before starting the conversion to avoid the above
issue.

The command completion was done early while aborting the commands in driver
unload path but outside lock to avoid the WARN_ON condition of performing
dma_free_attr within the lock. However this caused race condition while
command completion via multiple paths causing system crash.
Hence complete the command early in unload path but within the lock to
avoid race condition.

Link up failure is observed as a result of flash read failure. Current
code does not check flash read return code where it relies on FW checksum
to detect the problem.
Add check of flash read failure to detect the problem sooner.

The device does not come online when the target port is online. There were
multiple RSCNs indicating multiple devices were affected. Driver is in the
process of finishing a fabric scan. A new RSCN (device up) arrived at the
tail end of the last fabric scan. Driver mistakenly thinks the new RSCN is
being taken care of by the previous fabric scan, where this notification is
cleared and not acted on. The laser needs to be blinked again to get the
device to show up.
To prevent driver from accidentally clearing the RSCN notification, each
RSCN is given a generation value. A fabric scan will scan for that
generation(s). Any new RSCN arrive after the scan start will have a new
generation value. This will trigger another scan to get latest data. The
RSCN notification flag will be cleared when the scan is associate to that
generation.

Eric Biggers <[email protected]> says:
Add support for Flash Memory Protector (FMP), which is the inline
encryption hardware on Exynos and Exynos-based SoCs.
Specifically, add support for the "traditional FMP mode" that works on
many Exynos-based SoCs including gs101. This is the mode that uses
"software keys" and is compatible with the upstream kernel's existing
inline encryption framework in the block and filesystem layers. I
plan to add support for the wrapped key support on gs101 at a later
time.
Tested on gs101 (specifically Pixel 6) by running the 'encrypt' group
of xfstests on a filesystem mounted with the 'inlinecrypt' mount
option.
This patchset applies to v6.10-rc6, and it has no prerequisites that
aren't already upstream.

Since the nonstandard inline encryption support on Exynos SoCs requires
that raw cryptographic keys be copied into the PRDT, it is desirable to
zeroize those keys after each request to keep them from being left in
memory. Therefore, add a quirk bit that enables the zeroization.
We could instead do the zeroization unconditionally. However, using a
quirk bit avoids adding the zeroization overhead to standard devices.

Add a variant op to allow host drivers to initialize nonstandard
crypto-related fields in the PRDT. This is needed to support inline
encryption on the "Exynos" UFS controller.
Note that this will be used together with the support for overriding the
PRDT entry size that was already added by commit ada1e653a5ea ("scsi: ufs:
core: Allow UFS host drivers to override the sg entry size").
