2025-01-15Bluetooth: btusb: add sysfs attribute to control USB alt settingYing Hsu
When a Bluetooth raw socket is open, the HCI event related to SCO connection changes are not dispatched to the hci_event module, and the underlying Bluetooth controller's USB Interface 1 will not be updated accordingly. This patch adds `isoc_alt` sysfs attribute, allowing user space to update the alternate setting of the USB interface alternate setting as needed.

2025-01-15io_uring/register: use stable SQ/CQ ring data during resizeJens Axboe
Normally the kernel would not expect an application to modify any of the data shared with the kernel during a resize operation, but of course the kernel cannot always assume good intent on behalf of the application. As part of resizing the rings, existing SQEs and CQEs are copied over to the new storage. Resizing uses the masks in the newly allocated shared storage to index the arrays, however it's possible that malicious userspace could modify these after they have been sanity checked. Use the validated and locally stored CQ and SQ ring sizing for masking to ensure the values are both stable and valid.

2025-01-15genirq: Provide IRQCHIP_MOVE_DEFERREDThomas Gleixner
The logic of GENERIC_PENDING_IRQ is backwards for historical reasons. Most interrupt controllers allow to move the interrupt from arbitrary contexts. If GENERIC_PENDING_IRQ is enabled by an architecture to support a chip, which requires the affinity change to happen in interrupt context, all other chips have to be marked with IRQF_MOVE_PCNTXT. That's tedious and there is no real good reason for the extra flags in the irq descriptor and the irq data status fields. In fact the decision whether interrupts can be moved in arbitrary context or not is a property of the interrupt chip. To simplify adoption for RISC-V provide a new mechanism which is enabled via a config switch and allows to add a flag to irq_chip::flags to request that interrupt affinity changes are deferred. Setting the top level chip of an interrupt evaluates the flag and maps it into the existing logic. The config switch and the various PCNTXT flags are temporary until x86 is converted over to this scheme. This intermediate step also allows trivial backporting of the mechanism to plug the affinity change race of various RISC-V interrupt controllers.

2025-01-15kbuild: rust: add PROCMACROLDFLAGSHONG Yifan
These are flags to be passed when linking proc macros for the Rust toolchain. If unset, it defaults to $(KBUILD_HOSTLDFLAGS). This is needed because the list of flags to link hostprogs is not necessarily the same as the list of flags used to link libmacros.so. When we build proc macros, we need the latter, not the former (e.g. when using a Rust compiler binary linked to a different C library than host programs). To distinguish between the two, introduce this new variable to stand out from KBUILD_HOSTLDFLAGS used to link other host progs.

If the transition into low power mode fails, then the CPU_PM framework invokes the PM notifier callback with CPU_PM_ENTER_FAILED to allow the drivers to undo the state changes.

The fec_enet_update_cbd function calls page_pool_dev_alloc_pages but did not handle the case when it returned NULL. There was a WARN_ON(!new_page) but it would still proceed to use the NULL pointer and then crash. This case does seem somewhat rare but when the system is under memory pressure it can happen. One case where I can duplicate this with some frequency is when writing over a smbd share to a SATA HDD attached to an imx6q. Setting /proc/sys/vm/min_free_kbytes to higher values also seems to solve the problem for my test case. But it still seems wrong that the fec driver ignores the memory allocation error and can crash.
