If the first directory entry in the root directory is not a bitmap
directory entry, 'bh' will not be released and reassigned, which
will cause a memory leak.

We found that when writing a large file through buffer write, if the
disk is inaccessible, exFAT does not return an error normally, which
leads to the writing process not stopping properly.
To easily reproduce this issue, you can follow the steps below:
1. format a device to exFAT and then mount (with a full disk erase)
2. dd if=/dev/zero of=/exfat_mount/test.img bs=1M count=8192
3. eject the device
You may find that the dd process does not stop immediately and may
continue for a long time.
The root cause of this issue is that during buffer write process,
exFAT does not need to access the disk to look up directory entries
or the FAT table (whereas FAT would do) every time data is written.
Instead, exFAT simply marks the buffer as dirty and returns,
delegating the writeback operation to the writeback process.
If the disk cannot be accessed at this time, the error will only be
returned to the writeback process, and the original process will not
receive the error, so it cannot be returned to the user side.
When the disk cannot be accessed normally, an error should be returned
to stop the writing process.
Implement sops->shutdown and ioctl to shut down the file system
when underlying block device is marked dead.

which could be built as a module. However, tpm2_sessions_init() wasn't

These drivers don't use the driver_data member of struct i2c_device_id,
so don't explicitly initialize this member.
This prepares putting driver_data in an anonymous union which requires
either no initialization or named designators. But it's also a nice
cleanup on its own.

tpm_dev_transmit prepares the TPM space before attempting command
transmission. However if the command fails no rollback of this
preparation is done. This can result in transient handles being leaked
if the device is subsequently closed with no further commands performed.
Fix this by flushing the space in the event of command transmission
failure.

When cleaning up defrag inodes at btrfs_cleanup_defrag_inodes(), called
during remount and unmount, we are freeing every node from the rbtree
that tracks inodes for auto defrag using
rbtree_postorder_for_each_entry_safe(), which doesn't modify the tree
itself. So once we unlock the lock that protects the rbtree, we have a
tree pointing to a root that was freed (and a root pointing to freed
nodes, and their children pointing to other freed nodes, and so on).
This makes further access to the tree result in a use-after-free with
unpredictable results.
Fix this by initializing the rbtree to an empty root after the call to
rbtree_postorder_for_each_entry_safe() and before unlocking.
Fixes: 276940915f23 ("btrfs: clear defragmented inodes using postorder in btrfs_cleanup_defrag_inodes()")

[BUG]
There are some reports about invalid data backref objectids, the report
looks like this:
BTRFS critical (device sda): corrupt leaf: block=333654787489792 slot=110 extent bytenr=333413935558656 len=65536 invalid data ref objectid value 2543
The data ref objectid is the inode number inside the subvolume.
But in above case, the value is completely sane, not really showing the
problem.
[CAUSE]
The root cause of the problem is the deprecated feature, inode cache.
This feature results a special inode number, -12ULL, and it's no longer
recognized by tree-checker, triggering the error.
The direct problem here is the output of data ref objectid. The value
shown is in fact the dref_root (subvolume id), not the dref_objectid
(inode number).
[FIX]
Fix the output to use dref_objectid instead.

When doing concurrent lseek(2) system calls against the same file
descriptor, using multiple threads belonging to the same process, we have
a short time window where a race happens and can result in a memory leak.
The race happens like this:
1) A program opens a file descriptor for a file and then spawns two
threads (with the pthreads library for example), lets call them
task A and task B;
2) Task A calls lseek with SEEK_DATA or SEEK_HOLE and ends up at
file.c:find_desired_extent() while holding a read lock on the inode;
3) At the start of find_desired_extent(), it extracts the file's
private_data pointer into a local variable named 'private', which has
a value of NULL;
4) Task B also calls lseek with SEEK_DATA or SEEK_HOLE, locks the inode
in shared mode and enters file.c:find_desired_extent(), where it also
extracts file->private_data into its local variable 'private', which
has a NULL value;
5) Because it saw a NULL file private, task A allocates a private
structure and assigns to the file structure;
6) Task B also saw a NULL file private so it also allocates its own file
private and then assigns it to the same file structure, since both
tasks are using the same file descriptor.
At this point we leak the private structure allocated by task A.
Besides the memory leak, there's also the detail that both tasks end up
using the same cached state record in the private structure (struct
btrfs_file_private::llseek_cached_state), which can result in a
use-after-free problem since one task can free it while the other is
still using it (only one task took a reference count on it). Also, sharing
the cached state is not a good idea since it could result in incorrect
results in the future - right now it should not be a problem because it
end ups being used only in extent-io-tree.c:count_range_bits() where we do
range validation before using the cached state.
Fix this by protecting the private assignment and check of a file while
holding the inode's spinlock and keep track of the task that allocated
the private, so that it's used only by that task in order to prevent
user-after-free issues with the cached state record as well as potentially
using it incorrectly in the future.

git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai:
"A fairly big update at this time, both in core and driver sides.
The core received rewrites in PCM buffer allocation handling and
locking optimizations, PCM rate updates followed by lots of cleanups.
In ASoC side, the legacy Intel drivers have been deprecated by AVS
drivers which leaded to the significant amount of code reduction.
SoundWire driver updates and other cleanups contributed more code
reduction, too.
USB-audio driver received a large cleanup of its big quirk table, and
the old snd_print*() API usages in many legacy drivers are replaced
with the standard print API.
Here are some highlights:
Core:
- More optimized locking in ALSA control code
- Rewrites of memalloc helpers for better DMA API usage
- Drop of obsoleted vmalloc PCM buffer helper API
- Continued MIDI2 UMP updates
- Support of a new user-space driven timer instance
- Update for more PCM support rates and cleanups
- Xrun counter report in the proc files
ASoC:
- Continued simplification and cleanup works for ASoC
- Extensive cleanups and refactoring of the Soundwire drivers
- Removal of Intel machine support obsoleted by the AVS driver
- Lots of DT schema conversions
- Machine support for many AMD and Intel x86 platforms
- Support for AMD ACP 7.1, Mediatek MT6367 and MT8365, Realtek
RTL1320 SoundWire and rev C, and Texas Instruments TAS2563
USB-audio:
- Add support of multiple control interfaces
- A large rewrite of quirk table with macros
- Support for RME Digiface USB
HD-audio:
- Cleanup of quirk code for Samsung Galaxy laptops
- Clean up of detection of Cirrus codecs
- C-Media CM9825 HD-audio codec support
Others:
- Rewrites to standard print API in a lot of legacy drivers"

of SCL Clock timing for first broadcast address should be adjusted to 200ns
at least. I3C device working as i2c device will see the broadcast to close
its Spike Filter then change to work at I3C mode. After that I3C open drain
SCL high level should be adjusted back.

Commit 734e1a860312 ("block: Prevent deadlocks when switching
elevators") introduced the function elv_iosched_load_module() to allow
loading an elevator module outside of elv_iosched_store() with the
target device queue not frozen, to avoid deadlocks. However, the "none"
scheduler does not have a module and as a result,
elv_iosched_load_module() always returns an error when trying to switch
to this valid scheduler.
Fix this by ignoring the return value of the request_module() call
done by elv_iosched_load_module(). This restores the behavior before
commit 734e1a860312, which was to ignore the request_module() result and
instead rely on elevator_change() to handle the "none" scheduler case.

There is not much point in keeping support for RZ/Five peripherals
enabled, as the RZ/Five platform option (ARCH_R9A07G043) is gated behind
NONPORTABLE. Hence drop all config options that enable built-in or
modular support for peripherals found on RZ/Five SoCs.
Disable USB_XHCI_RCAR explicitly, as its value defaults to the value of
ARCH_RENESAS, which is still enabled.

Pull x86 memory management updates from Thomas Gleixner:
- Make LAM enablement safe vs. kernel threads using a process mm
temporarily as switching back to the process would not update CR3 and
therefore not enable LAM causing faults in user space when using
tagged pointers. Cure it by synchronizing LAM enablement via IPIs to
all CPUs which use the related mm.
- Cure a LAM harmless inconsistency between CR3 and the state during
context switch. It's both confusing and prone to lead to real bugs
- Handle alt stack handling for threads which run with a non-zero
protection key. The non-zero key prevents the kernel to access the
alternate stack. Cure it by temporarily enabling all protection keys
for the alternate stack setup/restore operations.
- Provide a EFI config table identity mapping for kexec kernel to
prevent kexec fails because the new kernel cannot access the config
table array
- Use GB pages only when a full GB is mapped in the identity map as
otherwise the CPU can speculate into reserved areas after the end of
memory which causes malfunction on UV systems.

Until now, the generic weak kgdb_roundup_cpus() has been used for kgdb on
RISCV. A custom one allows to debug CPUs that are stuck with interrupts
disabled with NMI support in the future. And using an IPI is better than
the generic one since it avoids the potential situation described in the
generic kgdb_call_nmi_hook(). As Andrew pointed out, once there is NMI
support, we can easily extend this and the CPU backtrace support
to use NMIs.
After this patch, the kgdb test show that:

The 'ld' and 'std' instructions require a 4-byte aligned displacement
because they are DS-form instructions. But the "m" asm constraint
doesn't enforce that.
That can lead to build errors if the compiler chooses a non-aligned
displacement, as seen with GCC 14:
/tmp/ccuSzwiR.s: Assembler messages:
/tmp/ccuSzwiR.s:2579: Error: operand out of domain (39 is not a multiple of 4)
make[5]: *** [scripts/Makefile.build:229: net/core/page_pool.o] Error 1
Dumping the generated assembler shows:
ld 8,39(8) # MEM[(const struct atomic64_t *)_29].counter, t
Use the YZ constraints to tell the compiler either to generate a DS-form
displacement, or use an X-form instruction, either of which prevents the
build error.
See commit 2d43cc701b96 ("powerpc/uaccess: Fix build errors seen with
GCC 13/14") for more details on the constraint letters.

Pull x86 APIC updates from Thomas Gleixner:
- Handle an allocation failure in the IO/APIC code gracefully instead
of crashing the machine.
- Remove support for APIC local destination mode on 64bit
Logical destination mode of the local APIC is used for systems with
up to 8 CPUs. It has an advantage over physical destination mode as
it allows to target multiple CPUs at once with IPIs. That advantage
was definitely worth it when systems with up to 8 CPUs were state of
the art for servers and workstations, but that's history.
In the recent past there were quite some reports of new laptops
failing to boot with logical destination mode, but they work fine
with physical destination mode. That's not a suprise because physical
destination mode is guaranteed to work as it's the only way to get a
CPU up and running via the INIT/INIT/STARTUP sequence. Some of the
affected systems were cured by BIOS updates, but not all OEMs provide
them.
As the number of CPUs keep increasing, logical destination mode
becomes less used and the benefit for small systems, like laptops, is
not really worth the trouble. So just remove logical destination mode
support for 64bit and be done with it.
