[RFC PATCH 1/2] libfs: Return ENOSPC when the directory offset range is exhausted

by cel＠kernel.org

From: Chuck Lever <chuck.lever(a)oracle.com> Testing shows that the EBUSY error return from mtree_alloc_cyclic() leaks into user space. The ERRORS section of "man creat(2)" says: > EBUSY O_EXCL was specified in flags and pathname refers > to a block device that is in use by the system > (e.g., it is mounted). ENOSPC is closer to what applications expect in this situation. Note that the normal range of simple directory offset values is 2..2^63, so hitting this error is going to be rare to impossible.

[PATCH v2] usb: dwc3: xilinx: make sure pipe clock is deselected in usb2 only mode

by Radhey Shyam Pandey

From: Neal Frager <neal.frager(a)amd.com> When the USB3 PHY is not defined in the Linux device tree, there could still be a case where there is a USB3 PHY is active on the board and enabled by the first stage bootloader. If serdes clock is being used then the USB will fail to enumerate devices in 2.0 only mode. To solve this, make sure that the PIPE clock is deselected whenever the USB3 PHY is not defined and guarantees that the USB2 only mode will work in all cases.

The core kernel skips this memory range when creating the hibernation image, therefore when coming back from hibernation the GGTT programming is lost. This seems to cause issues with broken resume where GuC FW fails to load: [drm] *ERROR* GT0: load failed: status = 0x400000A0, time = 10ms, freq = 1250MHz (req 1300MHz), done = -1 [drm] *ERROR* GT0: load failed: status: Reset = 0, BootROM = 0x50, UKernel = 0x00, MIA = 0x00, Auth = 0x01 [drm] *ERROR* GT0: firmware signature verification failed [drm] *ERROR* CRITICAL: Xe has declared device 0000:00:02.0 as wedged. Current GGTT users are kernel internal and tracked as pinned, so it should be possible to hook into the existing save/restore logic that we use for dgpu, where the actual evict is skipped but on restore we importantly restore the GGTT programming. This has been confirmed to fix hibernation on at least ADL and MTL, though likely all igpu platforms are affected. This also means we have a hole in our testing, where the existing s4 tests only really test the driver hooks, and don't go as far as actually rebooting and restoring from the hibernation image and in turn powering down RAM (and therefore losing the contents of stolen). v2 (Brost) - Remove extra newline and drop unnecessary parentheses.

[PATCH v2] ACPI: platform-profile: Fix CFI violation when accessing sysfs files

by Nathan Chancellor

When an attribute group is created with sysfs_create_group(), the ->sysfs_ops() callback is set to kobj_sysfs_ops, which sets the ->show() and ->store() callbacks to kobj_attr_show() and kobj_attr_store() respectively. These functions use container_of() to get the respective callback from the passed attribute, meaning that these callbacks need to be the same type as the callbacks in 'struct kobj_attribute'. However, the platform_profile sysfs functions have the type of the ->show() and ->store() callbacks in 'struct device_attribute', which results a CFI violation when accessing platform_profile or platform_profile_choices under /sys/firmware/acpi because the types do not match: CFI failure at kobj_attr_show+0x19/0x30 (target: platform_profile_choices_show+0x0/0x140; expected type: 0x7a69590c) There is no functional issue from the type mismatch because the layout of 'struct kobj_attribute' and 'struct device_attribute' are the same, so the container_of() cast does not break anything aside from CFI. Change the type of platform_profile_choices_show() and platform_profile_{show,store}() to match the callbacks in 'struct kobj_attribute' and update the attribute variables to match, which resolves the CFI violation.

[PATCH v3 00/15] media: stm32: introduction of CSI / DCMIPP for STM32MP25

by Alain Volmat

This series introduces the camera pipeline support for the STM32MP25 SOC. The STM32MP25 has 3 pipelines, fed from a single camera input which can be either parallel or csi. This series adds the basic support for the 1st pipe (dump) which, in term of features is same as the one featured on the STM32MP13 SOC. It focuses on introduction of the CSI input stage for the DCMIPP, and the CSI specific new control code for the DCMIPP. One of the subdev of the DCMIPP, dcmipp_parallel is now renamed as dcmipp_input since it allows to not only control the parallel but also the csi interface.
