[$] Compiling Rust to readable C with Eurydice

2026-01-31 00:09:24

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

2026-01-30 23:26:14

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.

Three stable kernel updates

2026-01-30 22:45:40

The 6.18.8, 6.12.68, and 6.6.122 stable kernel updates have been released; each contains another set of important fixes.

Security updates have been issued by AlmaLinux (curl, gimp:2.8, glibc, grafana, grafana-pcp, kernel, osbuild-composer, php:8.3, python-urllib3, python3.11, and python3.12), Debian (chromium), Mageia (ceph, gpsd, libxml2, openjdk, openssl, and xen), SUSE (abseil-cpp, assertj-core, coredns, freerdp, java-11-openjdk, java-25-openjdk, libxml2, openssl-1_0_0, openssl-1_1, python, python-filelock, and python311-sse-starlette), and Ubuntu (kernel, linux, linux-aws, linux-aws-hwe, linux-hwe, linux-kvm, linux-oracle, linux, linux-aws, linux-kvm, linux-lts-xenial, linux-aws-fips, linux-fips, linux-fips, and texlive-bin).

A proposed governance structure for openSUSE

2026-01-29 23:44:17

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

2026-01-29 23:36:23

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.
