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, 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 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" * tag 'driver-core-7.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/driver-core/driver-core: (129 commits) rust: pci: expose the allocated interrupt type PCI: Add pci_irq_type() to query the allocated interrupt type rust: pci: remove request_irq() and request_threaded_irq() from Device rust: pci: resolve IRQ in index() and embed IrqRequest in IrqVector rust: pci: convert IrqVectorRegistration to a lifetime-managed owning type kernfs: avoid iattr allocation in listxattr rust: serdev: use ThisModule::as_ptr() instead of field access ACPI/IORT: use platform_device_set_fwnode() ACPI/APMT: use platform_device_set_fwnode() firmware_loader: do not queue completed sysfs fallback requests rust: pci: Mark Device refcount methods inline rust: irq: make Registration compatible with lifetime-bound drivers rust: net/phy: remove expansion from doc rust: dma: return zero for Coherent reads past EOF rust: io: register: use path fragment for alias destination rust: io: register: remove unused rule arguments rust: io: register: dispatch shortcut rules internally MAINTAINERS: add sys_soc.h to DRIVER CORE rust: debugfs: remove unsafe blocks from traits impl for Vec rust: debugfs: migrate debugfs traits requirements to zerocopy ...

platform/x86: think-lmi: Fix current password length check

2026-08-18T16:28:32+00:00

current_password_store() checks the password length before removing the trailing newline, which can reject valid passwords that are exactly ->maxlen bytes long. It also passes ->maxlen to strscpy(), which truncates passwords without a newline. Use strchrnul() to measure the password length up to the newline, then copy that many bytes and add a trailing NUL terminator using strscpy().

platform/x86: redmi-wmi: report EC state change events

2026-08-18T14:30:49+00:00

The Redmibook EC/firmware fully handles the keyboard backlight cycle, the OEM preset power mode (Fn+K) and the Fn lock toggle by itself, and sends a WMI event carrying the resulting state in the third payload byte. These events are currently swallowed with KE_IGNORE, so userspace never learns that the state changed and cannot give the user any feedback (OSD), even though the WMI event is the only notification channel for these EC-driven changes. Report them as key presses instead: - keyboard backlight cycle -> KEY_KBDILLUMTOGGLE - OEM preset power mode -> KEY_PERFORMANCE - Fn lock toggle -> KEY_FN_ESC Desktops that only look at the keycode get the usual hotkey behaviour; since sparse-keymap emits MSC_SCAN with the raw payload before the key event, an OSD daemon can additionally recover the exact new state from byte 2 (e.g. backlight Off/Low/High/Auto is 0x00/0x05/0x0a/0x80). Note that the power mode event must keep being read from the WMI device in any case: on the TM2209 the ACPI event handler (EV20) applies the mode change as a side effect of building the event payload for _WED. Tested on Redmi Book Pro 15 2023 (TM2209).
