The end of Clear Linux

✇LWN

Intel has announced the abrupt end of its Clear Linux cloud-oriented distribution:

After years of innovation and community collaboration, we're ending support for Clear Linux OS. Effective immediately, Intel will no longer provide security patches, updates, or maintenance for Clear Linux OS, and the Clear Linux OS GitHub repository will be archived in read-only mode. So, if you're currently using Clear Linux OS, we strongly recommend planning your migration to another actively maintained Linux distribution as soon as possible to ensure ongoing security and stability.

[$] How to write Rust in the kernel: part 3

✇LWN
Par :daroc
18 juillet 2025 à 13:14

The interfaces between C and Rust in the kernel have grown over time; any non-trivial Rust driver will use a number of these. Tasks like allocating memory, dealing with immovable structures, and interacting with locks are necessary for handling most devices. There are also many subsystem-specific bindings, but the focus this time will be on an overview of the bindings that all kernel Rust code can be expected to use.

[$] Scheduler medley: time-slice extension, sched_ext deadline servers, and LRU batching.

✇LWN
Par :corbet
17 juillet 2025 à 14:11
Decades after its creation, the Linux CPU scheduler remains an area of active development; it is difficult to find a time slice to cover every interesting scheduler change. In an attempt to catch up, the time has come to round-robin through a few patches that have been circulating recently. The work at hand focuses on a new attempt at time-slice extension, the creation of a deadline server for sched_ext tasks, and keeping tasks on isolated CPUs from being surprised by LRU batching.

Version 0.50.0 of Hyprland, a compositor for Wayland, has been released. Changes include a new render-scheduling option that "can drastically improve FPS on underpowered devices, while coming at no performance or latency cost when the system is doing alright", an option to exclude applications from screen sharing, a new test suite, and more.

[$] Linux and Secure Boot certificate expiration

✇LWN
Par :jake
16 juillet 2025 à 18:00
Linux users who have Secure Boot enabled on their systems knowingly or unknowingly rely on a key from Microsoft that is set to expire in September. After that point, Microsoft will no longer use that key to sign the shim first-stage UEFI bootloader that is used by Linux distributions to boot the kernel with Secure Boot. But the replacement key, which has been available since 2023, may not be installed on many systems; worse yet, it may require the hardware vendor to issue an update for the system firmware, which may or may not happen. It seems that the vast majority of systems will not be lost in the shuffle, but it may require extra work from distributors and users.

[$] Fedora SIG changes Python packaging strategy

Fedora's NeuroFedora special-interest group (SIG) is considering a change of strategy when it comes to packaging Python modules. The SIG, which consists of three active members, is struggling to keep up with maintaining the hundreds of packages that it has taken on. What's more, it's not clear that the majority of packages are even being consumed by Fedora users; the group is trying to determine the right strategy to meet its goals and shed unnecessary work. If its new packaging strategy is successful, it may point the way to a more sustainable model for Linux distributions to provide value to users without trying to package everything under the sun.

[$] Enforcement (or not) for module-specific exported symbols

✇LWN
Par :corbet
15 juillet 2025 à 13:59
Loadable kernel modules require access to kernel data structures and functions to get their job done; the kernel provides this access by way of exported symbols. Almost since this mechanism was created, there have been debates over which symbols should be exported, and how. The 6.16 kernel gained a new export mechanism that limits access to symbols to specific kernel modules. That code is likely to change soon, but the addition of an enforcement mechanism has since been backed out.

[$] Following up on the Python JIT

✇LWN
Par :jake
14 juillet 2025 à 08:49
Performance of Python programs has been a major focus of development for the language over the last five years or so; the Faster CPython project has been a big part of that effort. One of its subprojects is to add an experimental just-in-time (JIT) compiler to the language; at last year's PyCon US, project member Brandt Bucher gave an introduction to the copy-and-patch JIT compiler. At PyCon US 2025, he followed that up with a talk on "What they don't tell you about building a JIT compiler for CPython" to describe some of the things he wishes he had known when he set out to work on that project. There was something of an elephant in the room, however, in that Microsoft dropped support for the project and laid off most of its Faster CPython team a few days before the talk.

Kernel prepatch 6.16-rc6

Linus has released 6.16-rc6 for testing; it includes a fix for a somewhat scary regression that came up over the week.

So I was flailing around blaming everybody and their pet hamster, because for a while it looked like a drm issue and then a netlink problem (it superficially coincided with separate issues with both of those subsystems).

But I did eventually figure out how to trigger it reliably and then it bisected nicely, and a couple of days have passed, and I'm feeling much better about the release again. We're back on track, and despite that little scare, I think we're in good shape.
