[$] API changes for the futex robust list

Par : jake
4 février 2026 à 17:48
The robust futex kernel API is a way for a user-space program to ensure that the locks it holds are properly cleaned up when it exits. But the API suffers from a number of different problems, as André Almeida described in a session in the "Gaming on Linux" microconference at the 2025 Linux Plumbers Conference in Tokyo. He had some ideas for a new API that would solve many of those problems, which he wanted to discuss with attendees; there is a difficult-to-trigger race condition that he wanted to talk about too.

[$] Sigil simplifies creating and editing EPUBs

Creating an ebook in EPUB format is easy, for certain values of "easy". All one really needs is a text editor, a few command-line utilities; also needed is a working knowledge of XHTML, CSS, along with an understanding of the format's structure and required boilerplate. Creating a well-formatted and attractive ebook is a bit harder. However, it can be made easier with an application custom-made for the purpose. Sigil is an EPUB editor that provides the tooling authors and publishers may be looking for.

[$] The future for Tyr

Par : daroc
3 février 2026 à 14:47

The team behind Tyr started 2025 with little to show in our quest to produce a Rust GPU driver for Arm Mali hardware, and by the end of the year, we were able to play SuperTuxKart (a 3D open-source racing game) at the Linux Plumbers Conference (LPC). Our prototype was a joint effort between Arm, Collabora, and Google; it ran well for the duration of the event, and the performance was more than adequate for players. Thankfully, we picked up steam at precisely the right moment: Dave Airlie just announced in the Maintainers Summit that the DRM subsystem is only "about a year away" from disallowing new drivers written in C and requiring the use of Rust. Now it is time to lay out a possible roadmap for 2026 in order to upstream all of this work.

[$] Modernizing swapping: introducing the swap table

Par : corbet
2 février 2026 à 15:28
The kernel's swap subsystem is a complex and often unloved beast. It is also a critical component in the memory-management subsystem and has a significant impact on the performance of the system as a whole. At the 2025 Linux Storage, Filesystem, Memory-Management and BPF Summit, Kairui Song outlined a plan to simplify and optimize the kernel's swap code. A first installment of that work, written with help from Chris Li, was merged for the 6.18 release. This article will catch up with the 6.18 work, setting the stage for a future look at the changes that are yet to be merged.

[$] Compiling Rust to readable C with Eurydice

Par : daroc
30 janvier 2026 à 16:09

A few years ago, the only way to compile Rust code was using the rustc compiler with LLVM as a backend. Since then, several projects, including Mutabah's Rust Compiler (mrustc), GCC's Rust support (gccrs), rust_codegen_gcc, and Cranelift have made enormous progress on diversifying Rust's compiler implementations. The most recent such project, Eurydice, has a more ambitious goal: converting Rust code to clean C code. This is especially useful in high-assurance software, where existing verification and compliance tools expect C. Until such tools can be updated to work with Rust, Eurydice could provide a smoother transition for these projects, as well as a stepping-stone for environments that have a C compiler but no working Rust compiler. Eurydice has been used to compile some post-quantum-cryptography routines from Rust to C, for example.

The Award for Excellence in Open Source goes to Greg Kroah-Hartman

Daniel Stenberg, the recipient of last year's Award for Excellence in Open Source from the European Open Source Academy, presented that award to this year's recipient: Greg Kroah-Hartman.

It's impossible to overstate the importance of the work Greg has done on Linux. In software, innovation grabs headlines, but stability saves lives and livelihoods. Every Android phone, every web server, every critical system running Linux depends on Greg's meticulous work. He ensures that when hospitals, banks, governments, and individuals rely on Linux, it doesn't fail them. His work represents the highest form of service: unglamorous, relentless, and essential.

A proposed governance structure for openSUSE

Par : corbet
29 janvier 2026 à 15:44
Jeff Mahoney, who holds a vice-president position at SUSE, has posted a detailed proposal for improving the governance of the openSUSE project.

It's meant to be a way to move from governance by volume or persistence toward governance by legitimacy, transparency, and process - so that disagreements can be resolved fairly and the project can keep moving forward. Introducing structure and predictability means it easier for newcomers to the project to participate without needing to understand decades of accumulated history. It potentially could provide a clearer roadmap for developers to find a place to contribute.

The stated purpose is to start a discussion; this is openSUSE, so he is likely to succeed.

[$] Sub-schedulers for sched_ext

Par : corbet
29 janvier 2026 à 15:36
The extensible scheduler class (sched_ext) allows the installation of a custom CPU scheduler built as a set of BPF programs. Its merging for the 6.12 kernel release moved the kernel away from the "one scheduler fits all" approach that had been taken until then; now any system can have its own scheduler optimized for its workloads. Within any given machine, though, it's still "one scheduler fits all"; only one scheduler can be loaded for the system as a whole. The sched_ext sub-scheduler patch series from Tejun Heo aims to change that situation by allowing multiple CPU schedulers to run on a single system.

Mourning Didier Spaier

We have received the sad news that Didier Spaier, maintainer of the blind-friendly Slackware-based Slint distribution, has recently passed away. Philippe Delavalade, who posted the announcement to the Slint mailing list, said:

Early 2015, I asked on the slackware list if brltty could be added in the installer; Didier answered promptly that he could do it on slint. Afterwards, he worked hard so that slint became as accessible as possible for visually impaired people.

You all know that all these years, he tried and succeeded to answer as quickly as possible to our issues and questions.

He will be irreplaceable.

OSI pauses 2026 board election cycle

Par : jzb
28 janvier 2026 à 18:13

The Open Source Initiative (OSI) has announced that it will not be holding the 2026 spring board election. Instead, it will be creating a working group to "review and improve OSI's board member selection process" and provide recommendations by September 2026:

The public election process was designed to gather community priorities and improve board member selection, while final appointments remained with the board.

Over time, that nuance has become a source of understandable confusion for community members. Many reasonably expected elections to function as elections normally do, and in fact, the board has generally adopted the electorate's recommendations. When a process feels unclear, trust suffers. When trust suffers, engagement becomes harder. This is especially problematic for an organization whose mission depends on legitimacy and credibility. [...]

OSI tried its experiment for the right reasons, but a variety of factors resulted in "elections" that are performatively democratic while being gameable and representative of only a small group, and we've learned from the results. Now we are making space to align our director selection process with our bylaws, to rebuild trust, and to develop better, more durable and truly representative participation in which the global stakeholder community can be heard.

LWN covered the previous OSI election in March 2025.
