[$] How to write Rust in the kernel: part 2

Linux Weekly News
1 hét 4 nap óta

In 2023, Fujita Tomonori wrote a Rust version of the existing driver for the Asix AX88796B embedded Ethernet controller. At slightly more than 100 lines, it's about as simple as a driver can be, and therefore is a useful touchstone for the differences between writing Rust and C in the kernel. Looking at the Rust syntax, types, and APIs used by the driver and contrasting them with the C version will help illustrate those differences.

Bcachefs may be headed out of the kernel

Linux Weekly News
1 hét 4 nap óta

The history of the bcachefs filesystem in the kernel has been turbulent, most recently with Linus Torvalds refusing a pull request for the 6.16-rc3 release. Torvalds has now pulled the code in question, but also said:

I think we'll be parting ways in the 6.17 merge window.

You made it very clear that I can't even question any bug-fixes and I should just pull anything and everything.

Honestly, at that point, I don't really feel comfortable being involved at all, and the only thing we both seemed to really fundamentally agree on in that discussion was "we're done".

Bcachefs developer Kent Overstreet has his own view of the situation. Both Torvalds and Overstreet refer to a seemingly private conversation where the pull request (and other topics) were discussed.

Coccinelle for Rust progress report (Collabora blog)

Linux Weekly News
1 hét 5 nap óta
Over on the Collabora blog, Tathagata Roy has an update on the progress of targeting the Coccinelle tool for matching and transforming source code to Rust. The Coccinelle for Rust project, which we covered in a 2024 talk by Roy at Kangrejos, is adding the ability to transform Rust programs and the goal is "to bring Coccinelle For Rust at par with Coccinelle For C in terms of basic functionalities". There is still work to be done to get there, but progress is being made in various areas. Computational Tree Logic (CTL) is the heart of Coccinelle, which takes semantic patches and generalizes them over Rust files. Prior to using this engine, CfR used an ad-hoc method for matching patterns of code. This engine is the same as the one used for Coccinelle for C, with a few minor changes. Most of the changes were idiomatic but to the same effect. More information on the engine and its language (CTL-VW) can be found in the POPL Paper. With a standard engine, each step of the matching process can be logged, allowing us to learn and reuse the same design patterns from Coccinelle for C, including critical test cases.

[$] Supporting kernel development with large language models

Linux Weekly News
1 hét 5 nap óta
Kernel development and machine learning seem like vastly different areas of endeavor; there are not, yet, stories circulating about the vibe-coding of new memory-management algorithms. There may well be places where machine learning (and large language models — LLMs — in particular) prove to be helpful on the edges of the kernel project, though. At the 2025 North-American edition of the Open Source Summit, Sasha Levin presented some of the work he has done putting LLMs to work to make the kernel better
