I'm announcing the release of the 5.4.291 kernel. All users of the 5.4 kernel series must upgrade. The updated 5.4.y git tree can be found at: git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-5.4.y and can be browsed at the normal kernel.org git web browser: https://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=summary thanks, greg k-h ------------ Documentation/devicetree/bindings/mmc/mmc-controller.yaml | 2 Makefile | 7 arch/alpha/include/uapi/asm/ptrace.h | 2 arch/alpha/kernel/asm-offsets.c | 2 arch/alpha/kernel/entry.S | 24 -

[PATCH] s390/vfio-ap: lock mdev object when handling mdev remove request

by Anthony Krowiak

The vfio_ap_mdev_request function in drivers/s390/crypto/vfio_ap_ops.c accesses fields of an ap_matrix_mdev object without ensuring that the object is accessed by only one thread at a time.

[PATCH 6.12.y 00/60] `alloc`, `#[expect]` and "Custom FFI"

by Miguel Ojeda

Hi Greg, Sasha, Please consider this series for 6.12.y. It should apply cleanly on top of v6.12.18. These are the patches to backport the `alloc` series for Rust, which will be useful for Rust Android Binder and others. It also means that, with this applied, we will not rely on the standard library `alloc` (and the unstable `cfg` option we used) anymore in any stable kernel that supports several Rust versions, so e.g. upstream Rust could consider removing that `cfg` if they needed. The entire series of cherry-picks apply almost cleanly (only 2 trivial conflicts) -- to achieve that, I included the `#[expect]` support, which will make future backports that use that feature easier anyway. That series also enabled some Clippy warnings. We could reduce the series, but the end result is warning-free and Clippy is opt-in anyway. Out-of-tree code could, of course, see some warnings if they use it. I also included a bunch of Clippy warnings cleanups for the DRM QR Code to have this series clean up to Rust 1.85.0 (the latest stable), but I could send them separately if needed. Finally, I included the "Custom FFI" series backport, which in turn solves the arm64 + Rust 1.85.0 + `CONFIG_RUST_FW_LOADER_ABSTRACTIONS=y` issue. It will also make future patches easier to backport, since we will have the same `ffi::` types. I tested that the entire series builds between every commit for x86_64 `LLVM=1` with the latest stable and minimum supported Rust compiler versions. I also ran my usual stable kernel tests on the end result; that is, boot-tested in QEMU for several architectures etc. In v6.12.18 for loongarch there is an unrelated error that was not there in v6.12.17 when I did a previous test run -- reported separately. Things could still break, so extra tests on the next -rc from users in Cc here would be welcome -- thanks!

[PATCH v3 1/2] regulator: dummy: force synchronous probing

by Christian Eggers

Sometimes I get a NULL pointer dereference at boot time in kobject_get() with the following call stack: anatop_regulator_probe() devm_regulator_register() regulator_register() regulator_resolve_supply() kobject_get() By placing some extra BUG_ON() statements I could verify that this is raised because probing of the 'dummy' regulator driver is not completed ('dummy_regulator_rdev' is still NULL). In the JTAG debugger I can see that dummy_regulator_probe() and anatop_regulator_probe() can be run by different kernel threads (kworker/u4:*). I haven't further investigated whether this can be changed or if there are other possibilities to force synchronization between these two probe routines. On the other hand I don't expect much boot time penalty by probing the 'dummy' regulator synchronously.

[PATCH] media: v4l2-dev: fix error handling in __video_register_device()

by Ma Ke

Once device_register() failed, we should call put_device() to decrement reference count for cleanup. Or it could cause memory leak. As comment of device_register() says, 'NOTE: _Never_ directly free @dev after calling this function, even if it returned an error! Always use put_device() to give up the reference initialized in this function instead.' Found by code review.
