Pull hardening fix from Kees Cook: - stddef: make __struct_group() UAPI C++-friendly (Alexander Lobakin) * tag 'hardening-v6.13-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux: stddef: make __struct_group() UAPI C++-friendly

stddef: make __struct_group() UAPI C++-friendly

2024-12-20T17:05:53Z

For the most part of the C++ history, it couldn't have type declarations inside anonymous unions for different reasons. At the same time, __struct_group() relies on the latters, so when the @TAG argument is not empty, C++ code doesn't want to build (even under `extern "C"`): ../linux/include/uapi/linux/pkt_cls.h:25:24: error: 'struct tc_u32_sel::::tc_u32_sel_hdr,' invalid; an anonymous union may only have public non-static data members [-fpermissive] The safest way to fix this without trying to switch standards (which is impossible in UAPI anyway) etc., is to disable tag declaration for that language. This won't break anything since for now it's not buildable at all. Use a separate definition for __struct_group() when __cplusplus is defined to mitigate the error, including the version from tools/.

thermal/thresholds: Fix uapi header macros leading to a compilation error

2024-12-16T20:30:20Z

The macros giving the direction of the crossing thresholds use the BIT macro which is not exported to the userspace. Consequently when an userspace program includes the header, it fails to compile. Replace the macros by their litteral to allow the compilation of userspace program using this header.

iommu/arm-smmu-v3: Improve uAPI comment for IOMMU_HW_INFO_TYPE_ARM_SMMUV3

2024-12-03T17:30:31Z

Be specific about what fields should be accessed in the idr result and give other guidance to the VMM on how it should generate the vIDR. Discussion on the list, and review of the qemu implementation understood this needs to be clearer and more detailed.

Pull more io_uring updates from Jens Axboe: - Remove a leftover struct from when the cqwait registered waiting was transitioned to regions. - Fix for an issue introduced in this merge window, where nop->fd might be used uninitialized. Ensure it's always set. - Add capping of the task_work run in local task_work mode, to prevent bursty and long chains from adding too much latency. - Work around xa_store() leaving ->head non-NULL if it encounters an allocation error during storing. Just a debug trigger, and can go away once xa_store() behaves in a more expected way for this condition. Not a major thing as it basically requires fault injection to trigger it. - Fix a few mapping corner cases - Fix KCSAN complaint on reading the table size post unlock. Again not a "real" issue, but it's easy to silence by just keeping the reading inside the lock that protects it. * tag 'io_uring-6.13-20242901' of git://git.kernel.dk/linux: io_uring/tctx: work around xa_store() allocation error issue io_uring: fix corner case forgetting to vunmap io_uring: fix task_work cap overshooting io_uring: check for overflows in io_pin_pages io_uring/nop: ensure nop->fd is always initialized io_uring: limit local tw done io_uring: add io_local_work_pending() io_uring/region: return negative -E2BIG in io_create_region() io_uring: protect register tracing io_uring: remove io_uring_cqwait_reg_arg

Pull char/misc/IIO/whatever driver subsystem updates from Greg KH: "Here is the 'big and hairy' char/misc/iio and other small driver subsystem updates for 6.13-rc1. Loads of things in here, and even a fun merge conflict! - rust misc driver bindings and other rust changes to make misc drivers actually possible. I think this is the tipping point, expect to see way more rust drivers going forward now that these bindings are present. Next merge window hopefully we will have pci and platform drivers working, which will fully enable almost all driver subsystems to start accepting (or at least getting) rust drivers. This is the end result of a lot of work from a lot of people, congrats to all of them for getting this far, you've proved many of us wrong in the best way possible, working code :) - IIO driver updates, too many to list individually, that subsystem keeps growing and growing... - Interconnect driver updates - nvmem driver updates - pwm driver updates - platform_driver::remove() fixups, loads of them - counter driver updates - misc driver updates (keba?) - binder driver updates and fixes - loads of other small char/misc/etc driver updates and additions, full details in the shortlog.
