mklinux-v7.0-mk2 released

corbet — Tue, 25 Aug 2026 20:34:31 +0000

For people who would like to experiment with the multi-kernel Linux concept, Cong Wang has announced the release of mklinux v7.0-mk2.

mklinux lets one machine run several independent Linux kernels at the same time on bare metal, without a hypervisor. A host kernel owns a pool of CPUs, memory and PCI devices, carves that pool into instances, and boots a spawn kernel into each instance through kexec_file_load(). Every spawn kernel runs natively on its own CPUs, its own physical memory and its own devices. Nothing is emulated and nothing is trapped; the only thing shared is what you choose to share.

Note that this is not the old MkLinux, which was a port to PowerPC Macintosh systems.

[$] Old-school calendaring at the command line with Remind

jzb — Tue, 25 Aug 2026 14:03:02 +0000

Remind is a command-line calendar and alarm program, with an optional Tk-based graphical interface, for Linux and Unix-like operating systems. It has its own scripting language that allows users to create reminders that are difficult (if not impossible) to specify in other calendaring programs. It is wholly unsuitable for use in corporate environments that require calendar sharing and exchanging meeting invitations; however, it may be precisely the calendaring tool for users who prefer the command line and fast, flexible tools that can help keep track of messy schedules.

Vanilla OS 3 released

[$] How to be safe from quantum computing

daroc — Mon, 24 Aug 2026 14:57:41 +0000

Practical quantum computers have been ten years away for the last several decades. Now, however, it's beginning to look as though they will be possible in just a few years. Recent research with obfuscated results demonstrated much lower memory requirements to factor ECDSA keys on a quantum computer, with work by other researchers in the open more than halving memory use compared to the state of the art in 2023. At the same time, computer manufacturers are boasting quantum processors that retain viable superpositions over longer periods. Given how slowly software updates filter out to stable systems, it's worth looking at what configuration changes and protocol updates are needed to be safe from quantum computers now.

Mourning Steve French

corbet — Sun, 23 Aug 2026 13:40:42 +0000

From Jeremy Allison we have the sad news of the passing of Steve French. He was the maintainer of the kernel's SMB filesystem code for many years, having only dropped that role due to health issues in the last week. "I've known Steve for over 20 years. He was a legend in the community, and a really good friend. He will be greatly missed. Farewell Steve." He will indeed be missed.

[$] Considering the OpenMDW license

corbet — Fri, 21 Aug 2026 13:42:29 +0000

The open-source world has been struggling for a few years now to understand how to approach large language models (LLMs) and the licensing applied to them. What constitutes "freedom" with respect to a black box filled with numerical weights? The process taken by the Open Source Initiative (OSI) in the development of its Open Source AI Definition was controversial at best, as was its output. Now, the Linux Foundation's Mike Dolan has brought a new license to the OSI for approval. It is called the OpenMDW ("Open Model, Data, and Weights"), and it aims to clarify licensing for the distribution of LLMs and related materials, but consensus is proving hard to find for this license as well.

[$] A look at the Quickshell desktop-component toolkit

jzb — Thu, 20 Aug 2026 19:39:51 +0000

Quickshell is a toolkit for building desktop components, such as toolbars or menus. It uses QML, which is a declarative language for designing GUI applications. Quickshell helps developers create graphical tools for common desktop use cases with a focus on ease of development. It offers a convenient method for writing user interfaces and has been adopted by a number of projects, such as caelestia-shell and DankMaterialShell, that provide desktop environments for minimal window managers like Sway and niri.

See the changelog for a full list of updates, enhancements, and bug fixes.

Supply chain attack on arrayref (Rust blog)

corbet — Thu, 20 Aug 2026 13:26:01 +0000

The Rust blog reports on a malicious crate, called proc-macro1, that was uploaded to the crates.io repository.

Furthermore, we discovered that the popular arrayref crate had recently been republished and made to depend on this crate, with the most recent versions yanked. We have removed the malicious version and unyanked the maliciously-yanked versions. Other crates by that author (internment, append-only-vec) were also affected so we have done the same for those, and locked the account as a precaution. We do not believe the author of arrayref to be acting maliciously, but their computer or credentials are likely compromised, and we are attempting to contact them.

RPM 6.1.0 released
