[PATCH v2 0/3] ext4: Add support for mounted updates to the superblock via an ioctl

by Theodore Ts'o via B4 Relay

This patch series enables a future version of tune2fs to be able to modify certain parts of the ext4 superblock without to write to the block device. The first patch fixes a potential buffer overrun caused by a maliciously moified superblock. The second patch adds support for 32-bit uid and gid's which can have access to the reserved blocks pool. The last patch adds the ioctl's which will be used by tune2fs. Signed-off-by: Theodore Ts'o <tytso(a)mit.edu> --- Changes in v2: - fix bugs that were detected using sparse - remove tune (unsafe) ability to clear certain compat faatures - add the ability to set the encoding and encoding flags for case folding - Link to v1: https://lore.kernel.org/r/20250908-tune2fs-v1-0-e3a6929f3355@mit.edu --- Theodore Ts'o (3): ext4: avoid potential buffer over-read in parse_apply_sb_mount_options() ext4: add support for 32-bit default reserved uid and gid values ext4: implemet new ioctls to set and get superblock parameters fs/ext4/ext4.h | 16 +++- fs/ext4/ioctl.c | 312 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++-- fs/ext4/super.c | 25 +++---- include/uapi/linux/ext4.h | 53 +++++++++++++ 4 files changed, 382 insertions(+), 24 deletions(-) --- base-commit: b320789d6883cc00ac78ce83bccbfe7ed58afcf0 change-id: 20250830-tune2fs-3376beb72403 Best regards, -- Theodore Ts'o <tytso(a)mit.edu>

[PATCH 1/2] soc: qcom: ocmem: fix device leak on lookup

by Johan Hovold

Make sure to drop the reference taken to the ocmem platform device when looking up its driver data. Note that holding a reference to a device does not prevent its driver data from going away so there is no point in keeping the reference. Also note that commit 0ff027027e05 ("soc: qcom: ocmem: Fix missing put_device() call in of_get_ocmem") fixed the leak in a lookup error path, but the reference is still leaking on success.

[REGRESSION] workqueue/writeback: Severe CPU hang due to kworker proliferation during I/O flush and cgroup cleanup

by Chenglong Tang

Hello, This is Chenglong from Google Container Optimized OS. I'm reporting a severe CPU hang regression that occurs after a high volume of file creation and subsequent cgroup cleanup. Through bisection, the issue appears to be caused by a chain reaction between three commits related to writeback, unbound workqueues, and CPU-hogging detection. The issue is greatly alleviated on the latest mainline kernel but is not fully resolved, still occurring intermittently (~1 in 10 runs). How to reproduce The kernel v6.1 is good. The hang is reliably triggered(over 80% chance) on kernels v6.6 and 6.12 and intermittently on mainline(6.17-rc7) with the following steps: Environment: A machine with a fast SSD and a high core count (e.g., Google Cloud's N2-standard-128). Workload: Concurrently generate a large number of files (e.g., 2 million) using multiple services managed by systemd-run. This creates significant I/O and cgroup churn. Trigger: After the file generation completes, terminate the systemd-run services. Result: Shortly after the services are killed, the system's CPU load spikes, leading to a massive number of kworker/+inode_switch_wbs threads and a system-wide hang/livelock where the machine becomes unresponsive (20s - 300s). Analysis and Problematic Commits 1. The initial commit: The process begins with a worker that can get stuck busy-waiting on a spinlock. Commit: ("writeback, cgroup: release dying cgwbs by switching attached inodes") Effect: This introduced the inode_switch_wbs_work_fn worker to clean up cgroup writeback structures. Under our test load, this worker appears to hit a highly contended wb->list_lock spinlock, causing it to burn 100% CPU without sleeping. 2. The Kworker Explosion: A subsequent change misinterprets the spinning worker from Stage 1, leading to a runaway feedback loop of worker creation. Commit: 616db8779b1e ("workqueue: Automatically mark CPU-hogging work items CPU_INTENSIVE") Effect: This logic sees the spinning worker, marks it as CPU_INTENSIVE, and excludes it from concurrency management. To handle the work backlog, it spawns a new kworker, which then also gets stuck on the same lock, repeating the cycle. This directly causes the kworker count to explode from <50 to 100-2000+. 3. The System-Wide Lockdown: The final piece allows this localized worker explosion to saturate the entire system. Commit: 8639ecebc9b1 ("workqueue: Implement non-strict affinity scope for unbound workqueues") Effect: This change introduced non-strict affinity as the default. It allows the hundreds of kworkers created in Stage 2 to be spread by the scheduler across all available CPU cores, turning the problem into a system-wide hang. Current Status and Mitigation Mainline Status: On the latest mainline kernel, the hang is far less frequent and the kworker counts are reduced back to normal (<50), suggesting other changes have partially mitigated the issue. However, the hang still occurs, and when it does, the kworker count still explodes (e.g., 300+), indicating the underlying feedback loop remains. Workaround: A reliable mitigation is to revert to the old workqueue behavior by setting affinity_strict to 1. This contains the kworker proliferation to a single CPU pod, preventing the system-wide hang. Questions Given that the issue is not fully resolved, could you please provide some guidance? 1. Is this a known issue, and are there patches in development that might fully address the underlying spinlock contention or the kworker feedback loop? 2. Is there a better long-term mitigation we can apply other than forcing strict affinity? Thank you for your time and help. Best regards, Chenglong

Sounds like: http://lkml.kernel.org/r/20250912103522.2935-1-jack@suse.cz Can you see whether those patches resolve the problem? Thanks. -- tejun

[PATCH v3 00/12] media: uvcvideo: Add support for orientation and rotation.

by Ricardo Ribalda

The ACPI has ways to annotate the location of a USB device. Wire that annotation to a v4l2 control. To support all possible devices, add a way to annotate USB devices on DT as well. The original binding discussion happened here: https://lore.kernel.org/linux-devicetree/20241212-usb-orientation-v1-1-0b69… The following patches are needed regardless if we finally add support for orientation and rotation or not: - media: uvcvideo: Always set default_value - media: uvcvideo: Set a function for UVC_EXT_GPIO_UNIT Signed-off-by: Ricardo Ribalda <ribalda(a)chromium.org> --- Changes in v3: - refactor dt bindings - add media: uvcvideo: Use current_value for read-only controls - get_(max|cur|def) = swentity_get_cur - virtual_entity add codestyle - Codestyle - Fix xu get_info and get_len - Drop ACPI_DEVICE_SWNODE_DEV_ROTATION - Add missing select V4L2_FWNODE - Link to v2: https://lore.kernel.org/r/20250605-uvc-orientation-v2-0-5710f9d030aa@chromi… Changes in v2: - Add support for rotation - Rename fwnode to swentity - Remove the patch to move the gpio file - Remove patches already in media-committers - Change priority of data origins - Patch mipi-disco - Link to v1: https://lore.kernel.org/r/20250403-uvc-orientation-v1-0-1a0cc595a62d@chromi… --- Ricardo Ribalda (12): media: uvcvideo: Always set default_value media: uvcvideo: Set a function for UVC_EXT_GPIO_UNIT media: v4l: fwnode: Support ACPI's _PLD for v4l2_fwnode_device_parse ACPI: mipi-disco-img: Do not duplicate rotation info into swnodes media: ipu-bridge: Use v4l2_fwnode_device_parse helper media: ipu-bridge: Use v4l2_fwnode for unknown rotations dt-bindings: media: Add usb-camera-module media: uvcvideo: Add support for V4L2_CID_CAMERA_ORIENTATION media: uvcvideo: Fill ctrl->info.selector earlier media: uvcvideo: Add uvc_ctrl_query_entity helper media: uvcvideo: Use current_value for read-only controls media: uvcvideo: Add support for V4L2_CID_CAMERA_ROTATION .../bindings/media/usb-camera-module.yaml | 46 +++++ MAINTAINERS | 1 + drivers/acpi/mipi-disco-img.c | 15 -- drivers/media/pci/intel/Kconfig | 1 + drivers/media/pci/intel/ipu-bridge.c | 58 +++--- drivers/media/usb/uvc/Kconfig | 1 + drivers/media/usb/uvc/Makefile | 3 +- drivers/media/usb/uvc/uvc_ctrl.c | 201 +++++++++++++++------ drivers/media/usb/uvc/uvc_driver.c | 22 ++- drivers/media/usb/uvc/uvc_entity.c | 3 +- drivers/media/usb/uvc/uvc_swentity.c | 107 +++++++++++ drivers/media/usb/uvc/uvcvideo.h | 22 +++ drivers/media/v4l2-core/v4l2-fwnode.c | 84 ++++++++- include/acpi/acpi_bus.h | 1 - include/linux/usb/uvc.h | 3 + 15 files changed, 441 insertions(+), 127 deletions(-) --- base-commit: afb100a5ea7a13d7e6937dcd3b36b19dc6cc9328 change-id: 20250403-uvc-orientation-5f7f19da5adb Best regards, -- Ricardo Ribalda <ribalda(a)chromium.org>
