rzg2l_clear_irq_int() and rzg2l_clear_tint_int() perform a
read-modify-write on the ISCR/TSCR status registers to clear the bit
for the interrupt just handled. Since these registers are
write-0-to-clear per bit, this is racy:
If another interrupt's status bit gets set between the read and the write,
that bit is written back as 0 by the software-constructed value, clearing
an interrupt that hasn't been serviced yet and losing it.
This can be reproduced by triggering multiple interrupts at once, e.g.:
gpioset -c gpiochip0 355=0 353=0 328=0 352=0
Fix this by writing back only the bit being cleared, with all other bits
set to 1, instead of read-modify-writing the whole register. Since 1-bits
are left unchanged by hardware, concurrently-set status bits for other
interrupts are preserved.

SYNC_BO does not constrain its size, so a request for zero bytes reaches
drm_clflush_virt_range(), which ends with an unconditional
clflushopt(end - 1). For an empty range that is the byte before the
mapping, and abo->mem.kva comes from vmap(), so the access lands in the
guard page below the vmalloc area and faults:
BUG: unable to handle page fault for address: ffffd16fbbc70fff
#PF: supervisor read access in kernel mode
Oops: Oops: 0000 [#1] SMP NOPTI
CPU: 7 UID: 1000 Comm: sync_bo_probe

do_syscall_64+0xa6/0x3d0
Any process that can open the render node can do this. Reproduced 3 of 3
times on a Strix Point NPU (1022:17f0), by calling SYNC_BO with size 0 on
an AMDXDNA_BO_SHARE object. The import arm takes the same request but
flushes the whole scatterlist, so it survives it.
Nothing needs flushing for an empty range, so answer before choosing a
path.

git://git.kernel.org/pub/scm/linux/kernel/git/driver-core/driver-core
Pull driver core updates from Danilo Krummrich:
"container_of:
- Apply typeof_member(), remove the local __mptr variable to
eliminate variable shadowing warnings on nested container_of()
calls, and remove unnecessary parentheses
core:
- Add driver name to probe debug print for initcall_debug
- Avoid repeatedly printing the same 'Fixed dependency cycle' log
- Unwind device_add() on attribute creation failure in
attribute_container_add_class_device()
- Remove statistics group if encryption group creation fails in
transport_add_class_device()
debugfs:
- Fix lockdown check for mmap_prepare()
- Warn if file creation failed due to uninitialized debugfs
device property:
- Implement fw_devlink support for software nodes by adding
software_node_add_links(), which creates fwnode links from
DEV_PROP_REF properties to enable automatic probe ordering. Add
kunit-managed fwnode helpers and test coverage
- Fix infinite loop in fwnode_for_each_child_node() when the
secondary fwnode has more than one child. Add test cases
- Fix out-of-bounds access in software_node_get_reference_args() when
called with index -1 (UINT_MAX)
- Refactor to use RAII approach with __free()
- Add Bartosz Golaszewski as software node reviewer
firmware loader:
- Fix race where a sysfs fallback request can complete before being
queued as pending, leading to a use-after-free on the next fallback
request
- Reject 0-size built-in firmware and fail the build on empty
firmware files in CONFIG_EXTRA_FIRMWARE
kobject:
- Provide __KOBJ_ATTR() and __KOBJ_ATTR_RO/WO() initialization macros
and allow the constification of kobject attributes, enabling them
to reside in read-only memory
platform:
- Provide platform_device_set_of_node(), platform_device_set_fwnode(),
and platform_device_set_of_node_from_dev() helpers that encapsulate
firmware node reference counting for dynamically allocated platform
devices
Convert all in-tree users that manually assigned dev.of_node or
dev.fwnode, fixing a pre-existing refcount bug in powermac. Switch
to counting references of all firmware node types, not only OF
nodes
- Unify the release path for dynamically allocated platform devices
by removing platform_device_release_full(). Amend the fwnode setter
API contract to warn if a primary software node is overwritten. Add
KUnit tests for correct software node removal on device
unregistration
Rust:
- Auxiliary:
- Add registration_data_with() closure-based API for invariant
ForLt types
- Debugfs:
- Migrate BinaryWriter and BinaryReaderMut trait requirements
from kernel::transmute traits to zerocopy traits
- Device:
- Add BoundInternal device context and InternalBoundContext trait
for bus abstractions that need internal access to a bound
device.
- Make the lifetime on Core and CoreInternal invariant to prevent
coercion to shorter lifetimes
- Devres:
- Fix race between concurrent revokers where the losing revoker
could return before the winning revoker finished dropping the
inner data, causing use-after-free.
- Ensure revocation is complete before the device finishes
unbinding by making the synchronization bidirectional.
- Add DevresLt<F: ForLt>, a wrapper around Devres that shortens
'static back to the caller's borrow scope. Implement ForLt and
CovariantForLt for Bar, IoMem, and ExclusiveIoMem
- Driver:
- Switch from index-based to pointer-based device ID info lookup,
storing static references in driver_data. Centralize device ID
handling in device_id.rs, removing the open-coded ACPI/OF
matching logic and duplicate ID table from driver.rs
- I/O:
- Make I/O regions typed (with a dynamically-sized Region type
for the existing untyped case), create view types representing
subregions of a mapped I/O region, and add io_project!() for
safely creating subviews.
- Split Io into a base trait (IoBase) and an extension trait (Io)
with a blanket implementation, preventing implementers from
overriding provided methods that unsafe code relies on.
- Add a SysMem backend for shared system memory with volatile
access, and make Coherent implement Io via an I/O view type.
Add IoSysMap as sum type of Mmio and SysMem. Add copying
methods (memcpy_{from,to}io()) and read_val()/write_val() for
typed access.
- Replace dma_read!()/dma_write!() with io_read!()/io_write!()
for primitives and copying methods for aggregates; drop the old
macros. Convert nova-core to use I/O projection.
- Fix internal shortcut rule dispatch in the register!() macro,
remove unused rule arguments, and use path fragments for alias
destinations
- IRQ:
- Make irq::Registration compatible with lifetime-bound drivers
by removing the 'static bound on Handler/ThreadedHandler and
replacing Devres<RegistrationInner> with direct
request_irq()/free_irq() calls. Handlers can now directly own
lifetime-bound device resources
- PCI:
- Convert IrqVectorRegistration to a lifetime-annotated owning
type, giving drivers explicit control over the allocation
lifetime. IrqVector embeds a resolved IrqRequest, making the
conversion infallible. Remove the redundant
request_irq()/request_threaded_irq() wrappers from pci::Device.
- Add pci_irq_type() C helper and expose it via irq_type() on
IrqVectorRegistration and IrqVector, returning PCI_IRQ_MSIX,
PCI_IRQ_MSI, or PCI_IRQ_INTX.
- Mark pci::Device refcount methods inline
- Serdev:
- Add Rust abstractions for the serial device bus, including
serdev::Driver trait, serdev::Device wrapping struct
serdev_device, and serdev::Adapter implementing
RegistrationOps. Includes a sample driver. Markus Probst takes
over as serdev maintainer for both C and Rust code
- Misc:
- Split ForLt into a base trait (providing the Of<'a> GAT) and an
unsafe CovariantForLt subtrait guaranteeing covariance,
enabling invariant types (e.g. those containing Mutex<&'bound T>)
to participate in the ForLt abstraction.
- Fix Coherent read past EOF returning -ERANGE instead of zero.
- Fix firmware example UB by avoiding null-pointer ARef
misc:
- Avoid iattr allocation in kernfs listxattr by using
kernfs_iattrs_noalloc().
- Unregister SoC bus on early device registration failure.
- Remove unused DMA_FENCE_TRACE Kconfig symbol.
- Fix /sys/module path in comment.
- Refactor ISA bus init to remove nested blocks.
- Remove redundant nodemask clears in numa_init().
- Add kernel-doc for fwnode_operations and sys_soc.h, mark
internal property data as private for kernel-doc, and add
property.h/fwnode.h to driver-api infrastructure docs.
- Add MAINTAINERS entry for sys_soc.h"

Replace irq_of_parse_and_map() with platform_get_irq(), which resolves
the interrupt from pdev->dev.of_node directly and returns a positive IRQ
or a negative errno (it never returns 0). Propagate the error on failure
instead of the previous open-coded "IRQ missing or invalid" / -EINVAL
message, so -EPROBE_DEFER is handled correctly. The rtc->irq field is a
signed short, so the negative error code is preserved.
np is still used by of_property_read_u32() for "st,lpc-mode", so it is
not removed.
Built for ARM (multi_v7_defconfig + CONFIG_RTC_DRV_ST_LPC) with LLVM=1;
drivers/rtc/rtc-st-lpc.o compiles cleanly.

Since the driver allocates the IRQ using devm_request_irq(), this means the
IRQ is going to be automatically unregistered by devres after
mv_rtc_remove() returns.
However, mv_rtc_remove() explicitly disables the hardware clock before
devres teardown happens so the interrupt handler may run while the clock is
disabled leading to a possible bus hang when accessing registers.

The driver has a match table for the i2c bus wired into its driver
structure, but the table is not exported with MODULE_DEVICE_TABLE().
Add the missing MODULE_DEVICE_TABLE() entry so module alias information
is generated for automatic module loading.
This is a source-level fix. It does not claim dynamic hardware
reproduction; the evidence is the driver-owned match table, its use by
the driver registration structure, and the missing module alias
publication.

The driver has an OF match table wired to .of_match_table, but does
not export the table with MODULE_DEVICE_TABLE().
Add the missing MODULE_DEVICE_TABLE(of, ...) entry so module alias
information is generated for OF based module autoloading.
This is a source-level fix. It does not claim dynamic hardware
reproduction; the evidence is the driver-owned match table, its use by
the platform driver, and the missing module alias publication.

Currently NVMe fault injection applies to every command routed through
nvme_should_fail(), which makes it hard to target a specific command
type when reproducing an issue in error-handling paths.
Add an "opcode" debugfs attribute alongside the existing "status" and
"dont_retry" knobs. It defaults to 0xffff, meaning "match any opcode"
and preserving the previous behavior. When set to a valid opcode
(<= 0xff), fault injection is only considered for commands whose opcode
matches.

nvme_query_fdp_info() is called per-path and therefore prone to races.
It populates head->nr_plids/head->plids for fdp registration.
But nothing protects that pair from concurrent access - two paths scanning
the same namespace can race to populate it.
Avoid the race by moving this initialization work to nvme_alloc_ns_head()

nvme_query_zone_info() returns either a negative errno or a positive
NVMe status code, but nvme_update_ns_info_block() only tests for the
negative case:
ret = nvme_query_zone_info(ns, lbaf, &zi);
if (ret < 0)
goto out;
If the device fails the Identify Namespace (I/O Command Set specific)
command, or the Identify Controller command issued by
nvme_set_max_append(), the positive status falls through and setup
continues with the zero-initialized zone info. nvme_update_zone_info()
then marks the queue zoned with chunk_sectors and ns->head->zsze set to
zero.
blk_validate_zoned_limits() does not check chunk_sectors, so the limits
commit succeeds. blk_revalidate_disk_zones() does reject the zero zone
size, but by then the limits are live and nothing rolls them back, so
I/O keeps being submitted to a zoned queue with a zero zone size and
disk_zone_no() shifts by ilog2(0):
nvme0n1: Invalid non power of two zone size (0)
UBSAN: shift-out-of-bounds in include/linux/blkdev.h:747:16

Any device, firmware or NVMe-oF target that fails this one command
reaches this.
Skip the zoned limits update in that case, and log which of the two
things happened: during a revalidation the queue keeps the zone
geometry it was last validated with, and on a first scan the namespace
is registered without zoned limits, so that it is still available as a
handle for admin commands. Neither of the paths in
nvme_query_zone_info() that return a positive status logs anything, so
the failure would otherwise be silent.
zi.zone_size is an exact indicator: every path that returns a positive
status returns before it is assigned, and after that the only failure
left is -ENODEV, which the caller already handles.

p1_rtc_read_time() called if (!regmap_test_bits(regmap, RTC_CTRL, RTC_EN))
to check if the RTC was enabled.
regmap_test_bits() returns 1 if the bit is set, 0 if not set, and a
negative error code (e.g. -EIO) if reading the control register fails.
Using !regmap_test_bits(...) evaluates a negative error code as boolean
false, causing I2C/regmap read failures to be ignored and incorrectly
proceeding to read time registers from a failing device.
Fix this by capturing the return value of regmap_test_bits() and returning

nvme_tcp_handle_c2h_data() finds the request by command id and checks
that it has a payload, but it does not check that the command asked for
data to be read. A controller that answers a write command with C2HData
therefore reaches nvme_tcp_recv_data(), where _copy_to_iter() hits
WARN_ON_ONCE(i->data_source) and returns 0. The receive path turns that
into -EFAULT and resets the controller.
No data is copied, so this is not memory corruption. What a controller
gets is a kernel warning it can raise at will, which is fatal on a host
booted with panic_on_warn.
The send path already knows the direction - it consults rq_data_dir()
when it builds a command - and nvme_tcp_handle_r2t() checks the length
and the offset of the request it names. The C2HData path does not check
the direction at all.
Reject a C2HData PDU whose command is not a read. Rejecting it fails
the command and resets the controller, as the neighbouring check in this
function does; what goes away is the warning.

Unlike the CRTC degamma path, which is guarded by
amdgpu_dm_verify_lut_sizes(), the per-plane degamma LUT size was never
validated before use. __set_dm_plane_degamma() passed the user-supplied
size straight into __is_lut_linear() and, for a non-linear LUT, into
__set_input_tf() -> __drm_lut_to_dc_gamma(), the latter always iterating
MAX_COLOR_LUT_ENTRIES entries regardless of the actual LUT size.
A malformed AMD_PLANE_DEGAMMA_LUT blob (e.g. a single entry) could thus
trigger a divide-by-zero in __is_lut_linear() or an out-of-bounds read in
__drm_lut_to_dc_gamma(). Reject any plane degamma LUT whose size does not
match MAX_COLOR_LUT_ENTRIES, mirroring the invariant the code already
asserts a few lines below (and which the CRTC path enforces).
The AMD_PLANE_DEGAMMA_LUT property is only exposed on builds with
AMD_PRIVATE_COLOR defined.

The Apple iMac11,1 (27-inch, Late 2009) uses a Mobility Radeon HD 4850
(RV770/DCE3.1) with a 2560x1440 internal panel on an internal
DisplayPort path. Without this fix the display stays dark under KMS.
This machine suffers from the same issue as iMac10,1 and iMac11,2:
Apple routes the internal display through Link B of the DIG encoder
instead of Link A. Add iMac11,1 to the existing DMI quirk and move
the Apple-specific encoder assignment into its own block, independent
of the DCE version check.
Additionally, the 2560x1440 panel requires RADEON_PLL_USE_FRAC_FB_DIV
and ATOM_ENCODER_CMD_DP_VIDEO_ON, limited to iMac11,1 via dmi_match()
to avoid affecting other boards.

When a queue is hung, the hang_detect_work is the
only way to recover it. However in amdgpu_userq_destroy(),
the hang_detect_work is cancelled too early,
resulting in amdgpu_userq_wait_for_last_fence()
may never return, leaving an uninterruptible dma_fence_wait()
hang there.
To fix this problem, this commit moves the cancelling of
hang_detect_work after amdgpu_userq_wait_for_last_fence(), and it has
to be before the unmap helper, because hang_detect_work resets the
queue, so it races with amdgpu_userq_unmap_helper() for MES operations
and queue state.
This commit splits amdgpu_userq_cleanup() into two parts:
1) amdgpu_userq_detach_doorbell(), which detaches the queue from
userq_doorbell_xa. This has to be called before the cancel, otherwise
the IRQ handlers (for example amdgpu_userq_process_fence_irq)
can re-schedule the hang_detect_work and the cancel is not final.
2) amdgpu_userq_fence_driver_free(), this has to be called after the
unmap helper, because it can release the seq64 slot that the GPU
writes fence values to.
Only one cancel_delayed_work_sync(&queue->hang_detect_work) is needed,
so other redundancies are removed.
