selinux: prune /sys/fs/selinux/user
Remove the previously deprecated /sys/fs/selinux/user interface aside
from a residual stub for userspace compatibility.
Commit d7b6918e22c7 ("selinux: Deprecate /sys/fs/selinux/user") started
the deprecation process for /sys/fs/selinux/user:
The selinuxfs "user" node allows userspace to request a list
of security contexts that can be reached for a given SELinux
user from a given starting context. This was used by libselinux
when various login-style programs requested contexts for
users, but libselinux stopped using it in 2020.
Kernel support will be removed no sooner than Dec 2025.
A pr_warn() message has been in place since Linux v6.13, and a 5
second sleep was introduced since Linux v6.17 to help make it more
noticeable.
We are now past the stated deadline of Dec 2025, so remove the
underlying functionality and replace it with a stub that returns a
'0\0' buffer to avoid breaking userspace. This also avoids a local DoS
from logspam and an uninterruptible sleep delay.

Fix an ath5k potential stack buffer overwrite.
Fix several issues in ath12k:

ffa_sched_recv_cb_update() used list_for_each_entry_safe() to search for
a matching partition and then tested the iterator against NULL. That is
not a valid end-of-list check for circular lists and can fall through
with an invalid pointer. Use a normal iterator and detect the not-found
case correctly before touching the partition state.
firmware: arm_ffa: Snapshot notifier callbacks under lock
Both notification handlers currently look up a notifier callback under
notify_lock, drop the lock, and then dereference the returned
notifier entry. A concurrent unregister can delete and free that
entry in the gap, leaving the handler to dereference stale memory.
Copy the callback pointer and callback data while notify_lock is
still held and invoke the callback only after the lock is dropped.
This keeps the existing callback execution model while removing the
use-after-free window in both the framework and non-framework
notification paths.
firmware: arm_ffa: Align RxTx buffer size before mapping
Commit 83210251fd70 ("firmware: arm_ffa: Use the correct buffer size during
RXTX_MAP") advertises PAGE_ALIGN(rxtx_bufsz) to firmware when mapping the
buffers but the driver continues to stores the minimum FF-A buffer size
in drv_info->rxtx_bufsz which is used elsewhere in the driver.
Align the size before storing it so that the allocation, validation and
FFA_RXTX_MAP all use the same buffer size.
Framework notifications carry an indirect message in the shared RX
buffer. Validate the reported offset and size before using them, reject
zero-length payloads, and ensure that any non-header payload starts at
the UUID field rather than in the middle of the message header.
Use the validated offset and size values for both kmemdup() and the UUID
parsing path so malformed firmware data cannot drive an out-of-bounds
read or an oversized allocation.
firmware: arm_ffa: Keep framework RX release under lock
The framework notification handler drops rx_lock before issuing
FFA_RX_RELEASE, leaving a window where another RX-buffer user can
start a new FF-A transaction before ownership has actually been
returned to firmware.
Move the FFA_RX_RELEASE calls so they execute while rx_lock is still
held on both the kmemdup() failure path and the normal success path.
While doing that, switch the handler to scoped_guard() to keep the
critical section explicit.
The register-based PARTITION_INFO_GET path trusted the firmware-provided
indices when copying partition descriptors into the caller buffer.
Reject inconsistent counts or index progressions so the copy loop cannot
write past the allocated array.
Extend the guidelines when to use fallback compatibles to cover to
common review responses. Devices are most likely compatible and should
use fallbacks when having:
1. Compatible programming interface, meaning one is a subset, and Linux
device drivers can use the subset to correctly match/bind and still
operate with the subset features.
2. Device variant discovery through some means, like registers.
Devices are incompatible and fallback is not suitable when that
fallback cannot be used by the drivers to match/bind. In the same time
commit message should clearly explain when the code suggests devices
are compatible, but the binding does not define them as such.
of/fdt: remove redundant memset in __unflatten_device_tree()
Now that memblock and slab allocators are the only allocators and both
return zero-initialized memory, zeroing the memory ourselves is
redundant. The allocators used are:
- kernel_tree_alloc uses kzalloc()
- early_init_dt_alloc_memory_arch() and dt_alloc_memory() both use
memblock_alloc()
Remove redundant memset after the allocation. No funtional change.
The 'wakeup-source' property already has its type defined in the core
schema. Remove the redundant 'type: boolean' from the binding file to
clean up the binding files.

Also, the unreg_driver label incorrectly calls
