2024-05-14Bluetooth: hci_bcm: Limit bcm43455 baudrate to 2000000Hans de Goede
Like the bcm43430a0 the bcm43455 BT does not support the 0xfc45 command to set the UART clock to 48 MHz and because of this it does not work at 4000000 baud. These chips are found on ACPI/x86 devices where the operating baudrate does not come from the firmware but is hardcoded at 4000000, which does not work. Make the driver_data for the "BCM2EA4" ACPI HID which is used for the bcm43455 BT point to bcm43430_device_data which limits the baudrate to 2000000.

2024-05-14Bluetooth: hci_intel: Convert to platform remove callback returning voidUwe Kleine-König
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

2024-05-14nbd: Fix signal handlingBart Van Assche
Both nbd_send_cmd() and nbd_handle_cmd() return either a negative error number or a positive blk_status_t value. nbd_queue_rq() converts these return values into a blk_status_t value. There is a bug in the conversion code: if nbd_send_cmd() returns BLK_STS_RESOURCE, nbd_queue_rq() should return BLK_STS_RESOURCE instead of BLK_STS_OK. Fix this, move the conversion code into nbd_handle_cmd() and fix the remaining sparse warnings.

2024-05-14net: micrel: Fix receiving the timestamp in the frame for lan8841Horatiu Vultur
The blamed commit started to use the ptp workqueue to get the second part of the timestamp. And when the port was set down, then this workqueue is stopped. But if the config option NETWORK_PHY_TIMESTAMPING is not enabled, then the ptp_clock is not initialized so then it would crash when it would try to access the delayed work. So then basically by setting up and then down the port, it would crash. The fix consists in checking if the ptp_clock is initialized and only then cancel the delayed work.

2024-05-14platform/x86: Add new Dell UART backlight driverHans de Goede
Dell All In One (AIO) models released after 2017 use a backlight controller board connected to an UART. In DSDT this uart port will be defined as: Name (_HID, "DELL0501") Name (_CID, EisaId ("PNP0501") Instead of having a separate ACPI device with an UartSerialBusV2() resource to model the backlight-controller, which would be the standard way to do this. The acpi_quirk_skip_serdev_enumeration() has special handling for this and it will make the serial port code create a serdev controller device for the UART instead of a /dev/ttyS0 char-dev. It will also create a dell-uart-backlight driver platform device for this driver to bind too. This new kernel module contains 2 drivers for this: 1. A simple platform driver which creates the actual serdev device (with the serdev controller device as parent) 2. A serdev driver for the created serdev device which exports the backlight functionality uses a standard backlight class device.

2024-05-14platform/x86: x86-android-tablets: Create LED device for Xiaomi Pad 2 bottom ↵Hans de Goede
bezel touch buttons The Xiaomi [Mi]Pad 2 has 3 menu / home / back capacitive touch-buttons on its bottom bezel. These are backlit by LEDs attached to a TPS61158 LED controller which is controlled by the "pwm_soc_lpss_2" PWM output. Create a LED class device for this, using the new input-events trigger as default trigger so that the buttons automatically light up on any input activity. Note alternatively a "leds_pwm" platform device could be created together with the necessary fwnode_s_ and a fwnode link to the PWM controller. There are 2 downsides to this approach: 1. The code would still need to pwm_get() the PWM controller to get/attach a fwnode for the PWM controller fwnode link and setting up the necessary fwnodes is non-trivial. So this would likely require more code then simply registering the LED class device directly. 2. Currently the leds_pwm driver and its devicetree bindings do not support limiting the maximum dutycycle to less then 100% which is required in this case (the leds_pwm driver can probably be extended to allow this).

Pull DSA and IAA accelerator mis-alignment fix from Arjan van de Ven: "The DSA (memory copy/zero/etc) and IAA (compression) accelerators in the Sapphire Rapids and Emerald Rapids SOCs turn out to have a bug that has security implications. Both of these accelerators work by the application submitting a 64 byte command to the device; this command contains an opcode as well as the virtual address of the return value that the device will update on completion... and a set of opcode specific values. In a typical scenario a ring 3 application mmaps the device file and uses the ENQCMD or MOVDIR64 instructions (which are variations of a 64 byte atomic write) on this mmap'd memory region to directly submit commands to a device hardware. The return value as specified in the command, is supposed to be 32 (or 64) bytes aligned in memory, and generally the hardware checks and enforces this alignment. However in testing it has been found that there are conditions (controlled by the submitter) where this enforcement does not happen... which makes it possible for the return value to span a page boundary. And this is where it goes wrong - the accelerators will perform the virtual to physical address lookup on the first of the two pages, but end up continue writing to the next consecutive physical (host) page rather than the consecutive virtual page. In addition, the device will end up in a hung state on such unaligned write of the return value. This patch series has the proposed software side solution consisting of three parts: - Don't allow these two PCI devices to be assigned to VM guests (we cannot trust a VM guest to behave correctly and not cause this condition) - Don't allow ring 3 applications to set up the mmap unless they have CAP_SYS_RAWIO permissions. This makes it no longer possible for non-root applications to directly submit commands to the accelerator - Add a write() method to the device so that an application can submit its commands to the kernel driver, which performs the needed sanity checks before submitting it to the hardware. This switch from mmap to write is an incompatible interface change to non-root userspace, but we have not found a way to avoid this. All software we know of uses a small set of accessor libraries for these accelerators, for which libqpl and libdml (on github) are the most common. As part of the security release, updated versions of these libraries will be released that transparently fall back to write().

2024-05-13net: prestera: Add flex arrays to some structsErick Archer
The "struct prestera_msg_vtcam_rule_add_req" uses a dynamically sized set of trailing elements. Specifically, it uses an array of structures of type "prestera_msg_acl_action actions_msg". The "struct prestera_msg_flood_domain_ports_set_req" also uses a dynamically sized set of trailing elements. Specifically, it uses an array of structures of type "prestera_msg_acl_action actions_msg". So, use the preferred way in the kernel declaring flexible arrays [1]. At the same time, prepare for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions). In this case, it is important to note that the attribute used is specifically __counted_by_le since the counters are of type __le32. The logic does not need to change since the counters for the flexible arrays are asigned before any access to the arrays. The order in which the structure prestera_msg_vtcam_rule_add_req and the structure prestera_msg_flood_domain_ports_set_req are defined must be changed to avoid incomplete type errors. Also, avoid the open-coded arithmetic in memory allocator functions [2] using the "struct_size" macro. Moreover, the new structure members also allow us to avoid the open- coded arithmetic on pointers. So, take advantage of this refactoring accordingly. This code was detected with the help of Coccinelle, and audited and modified manually.
