Relocate the code that technically fits in the pin initializer into the
initializer itself.
While, thanks to pin_init_scope(), it is also possible to keep it as is,
moving appropriate code into the initializer has the advantage that it
structures the dependencies of fields naturally.
For instance, intermediate data that is only needed for a single field
goes into the initializer block of this field, making it obvious that it
is not needed by anything else.
On the other hand, intermediate data that is needed for multiple fields
to initialize remains above the initializer, naturally indicating that
it is needed my multiple fields.

alloc_workqueue() can return NULL on memory allocation failure. Without
proper error checking, this may lead to a NULL pointer dereference when
queue_work() is later called with the NULL workqueue pointer in
epf_ntb_epc_init().
Add a NULL check immediately after alloc_workqueue() and return -ENOMEM on
failure to prevent the driver from loading with an invalid workqueue
pointer.

For XDP_TX action, the xdp_buff is converted to xdp_frame by
xdp_convert_buff_to_frame(). The memory type of the resulting xdp_frame
depends on the memory type of the xdp_buff. For page pool based xdp_buff
it produces xdp_frame with memory type MEM_TYPE_PAGE_POOL. For zero copy
XSK pool based xdp_buff it produces xdp_frame with memory type
MEM_TYPE_PAGE_ORDER0. However, stmmac_xdp_xmit_back() does not check the
memory type and always uses the page pool type, this leads to invalid
mappings and causes the crash. Therefore, check the xdp_buff memory type
in stmmac_xdp_xmit_back() to fix this issue.

Currently work items enqueued by schedule_delayed_work() use "system_wq" (a
per-CPU wq) while queue_delayed_work() uses WORK_CPU_UNBOUND (used when a
CPU is not specified). The same applies to schedule_work() that is using
system_wq and queue_work(), that makes use again of WORK_CPU_UNBOUND. This
lack of consistency cannot be addressed without refactoring the API.
This continues the effort to refactor workqueue APIs, which began with the
introduction of new workqueues and a new alloc_workqueue() flag in:
128ea9f6ccfb ("workqueue: Add system_percpu_wq and system_dfl_wq")
930c2ea566af ("workqueue: Add new WQ_PERCPU flag")
Replace system_wq with system_percpu_wq, keeping the same behavior. The
old wq (system_wq) will be kept for a few release cycles.

CPU is not specified). The same applies to schedule_work() that is using
system_wq and queue_work(), that makes use again of WORK_CPU_UNBOUND. This
lack of consistency cannot be addressed without refactoring the API.
alloc_workqueue() treats all queues as per-CPU by default, while unbound
workqueues must opt-in via WQ_UNBOUND.
This default is suboptimal: most workloads benefit from unbound queues,
allowing the scheduler to place worker threads where they're needed and
reducing noise when CPUs are isolated.
This continues the effort to refactor workqueue APIs, which began with the
introduction of new workqueues and a new alloc_workqueue() flag in:
128ea9f6ccfb ("workqueue: Add system_percpu_wq and system_dfl_wq")
930c2ea566af ("workqueue: Add new WQ_PERCPU flag")
Add WQ_PERCPU to explicitly request alloc_workqueue() to be per-CPU when
WQ_UNBOUND has not been specified.
With the introduction of the WQ_PERCPU flag (equivalent to !WQ_UNBOUND),
any alloc_workqueue() caller that doesn't explicitly specify WQ_UNBOUND
must now use WQ_PERCPU.
Once migration is complete, WQ_UNBOUND can be removed and unbound will
become the implicit default.

If you force-disable mitigations on the kernel cmdline, for SPEC_STORE_BYPASS
this ends up with the prctl returning -ENXIO, but contrary to the current docs
for the other controls it returns -EPERM. Fix that.
Note that this return value should probably be considered a bug. But, making
the behaviour consistent with the current docs seems more likely to break
existing users than help anyone out in practice, so just "fix" it by
specifying it as correct.
Since this is getting more wordy and confusing, also be more explicit about
"control is not possible" be mentioning the boot configuration, to better
distinguish this case conceptually from the FORCE_DISABLE failure mode.

Until now, each landlock_request struct were allocated on the stack, even
if not really used, because is_access_to_paths_allowed() unconditionally
modified the passed references. Even if the changed landlock_request
variables are not used, the compiler is not smart enough to detect this
case.
To avoid this issue, explicitly disable the related code when
CONFIG_AUDIT is not set, which enables elision of log_request_parent*
and associated caller's stack variables thanks to dead code elimination.
This makes it possible to reduce the stack frame by 32 bytes for the
path_link and path_rename hooks, and by 20 bytes for most other
filesystem hooks.
Here is a summary of scripts/stackdelta before and after this change
when CONFIG_AUDIT is disabled:
current_check_refer_path 560 320 -240
current_check_access_path 328 184 -144
hook_file_open 328 184 -144
is_access_to_paths_allowed 376 360 -16
Also, add extra pointer checks to be more future-proof.

commit f3a296405b6e ("PCI: dwc: Strengthen the MSI address allocation
logic") strengthened the iMSI-RX target address allocation logic to handle
64-bit addresses for platforms without 32-bit DMA addresses. However, it
still left 32-bit MSI capable endpoints (EPs) non-functional on such
platforms.
Per DWC databook r6.21a, sec 3.10.2.3, it states:
"The iMSI-RX is programmed with an address (MSI_CTRL_ADDR_OFF and
MSI_CTRL_UPPER_ADDR_OFF) that is used as the system MSI address. When an
inbound MWr request is passed to the AXI bridge and matches this address
as well as the conditions specified for an MSI memory write request, an
MSI interrupt is detected. When this MWr is about to be driven onto the
AXI bridge master interface1, it is dropped and never appears on the AXI
bus."
Since iMSI-RX MSI_CTRL_ADDR doesn't require actual system memory mapping,
any 32-bit address that won't be used for BAR memory allocations can be
assigned. So assign cfg0_base to the iMSI-RX target address as the first
option if it's a 32-bit address, which satisfies this requirement.
Otherwise, fallback to the existing coherent allocation.

The hp_populate_*_elements_from_package() functions in the hp-bioscfg
driver contain out-of-bounds array access vulnerabilities.
These functions parse ACPI packages into internal data structures using
a for loop with index variable 'elem' that iterates through
enum_obj/integer_obj/order_obj/password_obj/string_obj arrays.
When processing multi-element fields like PREREQUISITES and
ENUM_POSSIBLE_VALUES, these functions read multiple consecutive array
elements using expressions like 'enum_obj[elem + reqs]' and
'enum_obj[elem + pos_values]' within nested loops.
The bug is that the bounds check only validated elem, but did not consider
the additional offset when accessing elem + reqs or elem + pos_values.
The fix changes the bounds check to validate the actual accessed index.

This patch modifies the ntfs3 driver by replacing the buffer_head-based
operations with the iomap ones.
Implementation details:
- Implements core iomap operations (ntfs_iomap_begin/end) for block mapping:
Proper handling of resident attributes via IOMAP_INLINE.
Support for sparse files through IOMAP_HOLE semantics.
Correct unwritten extent handling for zeroing operations.
- Replaces custom implementations with standardized iomap helpers:
Converts buffered reads to use iomap_read_folio and iomap_readahead.
Implements iomap_file_buffered_write for write operations.
Uses iomap_dio_rw for direct I/O paths.
Migrates zero range operations to iomap_zero_range.
- Preserves special handling paths for compressed files
- Implements proper EOF/valid data size management during writes

Syzbot reported a task hung in ni_readpage_cmpr (now ni_read_folio_cmpr).
This is caused by a lock inversion deadlock involving the inode mutex
(ni_lock) and page locks.
Scenario:
1. Task A enters ntfs_read_folio() for page X. It acquires ni_lock.
2. Task A calls ni_read_folio_cmpr(), which attempts to lock all pages in
the compressed frame (including page Y).
3. Concurrently, Task B (e.g., via readahead) has locked page Y and
calls ntfs_read_folio().
4. Task B waits for ni_lock (held by A).
5. Task A waits for page Y lock (held by B).
-> DEADLOCK.
The fix is to restructure locking: do not take ni_lock in ntfs_read_folio().
Instead, acquire ni_lock inside ni_read_folio_cmpr() ONLY AFTER all required
page locks for the frame have been successfully acquired. This restores the
correct lock ordering (Page Lock -> ni_lock) consistent with VFS.

Do not keep preallocated clusters for sparsed and compressed files.
Preserving preallocation in these cases causes fsx failures when running
with sparse files and preallocation enabled.

Some xfstests expect fsync() on a file or directory to also persist
directory metadata up the parent chain. Using generic_file_fsync() is not
sufficient for ntfs, because parent directories are not explicitly
written out.

KASAN reported a stack-out-of-bounds access in ima_appraise_measurement
from is_bprm_creds_for_exec:
BUG: KASAN: stack-out-of-bounds in ima_appraise_measurement+0x12dc/0x16a0
Read of size 1 at addr ffffc9000160f940 by task sudo/550
The buggy address belongs to stack of task sudo/550
and is located at offset 24 in frame:
ima_appraise_measurement+0x0/0x16a0
This frame has 2 objects:
[48, 56) 'file'
[80, 148) 'hash'
This is caused by using container_of on the *file pointer. This offset
calculation is what triggers the stack-out-of-bounds error.
In order to fix this, pass in a bprm_is_check boolean which can be set
depending on how process_measurement is called. If the caller has a
linux_binprm pointer and the function is BPRM_CHECK we can determine
is_check and set it then. Otherwise set it to false.

The current probe function of the driver is implemented by using
plain old APIs. As Geert noted, one of the error paths has a mistake
that may lead to a wrong call. Instead of targeting that particular
issue, convert the driver to use device managed APIs altogether.
It's not needed per se (driver can never be removed once loaded),
but it simplifies coding and error handling.
