Flexible arrays — arrays that are declared as the final member of a structure and which have a size determined at run time — have long drawn the attention of developers seeking to harden the kernel against buffer-overflow vulnerabilities. These arrays have reliably been a source of bugs, so anything that can be done to ensure that operations on them stay within bounds is...

Image-based Linux distributions have seen increasing popularity, recently. They promise reliability and security, but pose packaging problems for existing distributions. Ryan Lahfa and Niklas Sturm spoke about the work that NixOS has done to enable an image-based workflow at this year's All Systems Go! conference in Berlin. Unfortunately, LWN was not able to cover the conference for scheduling reasons, but the videos of the...

Man pages maintainer Alejandro Colomar announced in September that he was suspending his work due to a lack of support. He has now let it be known that funding has been found for the next year at least: We've been talking for a couple of months, and we have already agreed to sign a contract through the LF [Linux Foundation], where a number of...

Version 2.1.0 of the LXQt lightweight Qt desktop environment has been released. The highlight of this release is support for multiple Wayland compositors: Through its new component lxqt-wayland-session, LXQt 2.1.0 supports 7 Wayland sessions (with Labwc, KWin, Wayfire, Hyprland, Sway, River and Niri), has two Wayland back-ends in lxqt-panel (one for kwin_wayland and the other general), and will add more later. All LXQt components...

Joshua Liebow-Feeser took to the stage at RustConf to describe the methodology that his team uses to encode arbitrary constraints in the Rust type system when working on the Fuchsia operating system (slides). The technique is not unknown to the Rust community, but Liebow-Feeser did a good job of both explaining the method and making a case for why it should be used more...

After a couple of years of effort, the BPF instruction set architecture has been accepted as RFC 9669, giving it a standard outside of the in-kernel implementation. This message from David Vernet (who also contributed an article on the standardization process last year) describes the process and why it is important: Though some vendors have already implemented BPF offloading capabilities without having a standardized...

OpenWrt is, despite its relatively low profile, one of our community's most important distributions; it runs untold numbers of network routers and has served as the base on which a lot of network-oriented development (including the bufferbloat-reduction work) has been done. At the beginning of 2024, a few members of the project announced a plan to design and produce a router device specifically designed...

The 6.12-rc6 kernel prepatch is out for testing. Linus says: "Another week, another rc. Nothing odd or special seems to be going on - this may be a bit on the bigger side for an rc6, but not hugely so, and nothing stands out."

Members of the Open Source Initiative (OSI) board sat down for a 45-minute "Ask Me Anything" (AMA) session at All Things Open in Raleigh, NC on October 29. Though the floor was open to any topic the audience might want to ask of the OSI board. Many of the questions were focused on the Open Source AI Definition (OSAID), which was announced the day...

The Rust blog has an update on its progress on some of its project goals. One of the project's flagship goals is to resolve the biggest blockers to Linux building on stable Rust: Finally, we have been finding an increasing number of stabilization requests at the compiler level, and so @wesleywiser and @davidtwco from the compiler team have started attending meetings to create a...

OpenStreetMap tends to dominate the space for open mapping data, but it is not the only project working in this area. At the 2024 Open Source Summit Japan, Marc Prioleau presented the Overture Maps Foundation, which is building and distributing a set of worldwide maps under open licenses. Overture may have a similar goal to OpenStreetMap, but its approach and intended uses are significantly...

Timothée Ravier has written a blog post about changes in the Fedora Atomic Desktops for Fedora Linux 41. Some of the notable new features for Atomic Desktops include bootloader updates enabled by default for UEFI systems, first steps towards using bootable containers, and more.

The Raspberry Pi project has announced a new version of Raspberry Pi OS. It includes a number of significant changes, the most notable of which is that the Raspberry Pi Desktop now uses Wayland by default for all Pi models using the labwc compositor: For most of this year, we have been working on porting labwc to the Raspberry Pi Desktop. This has very...

The kernel graphics driver for the Apple M1 and M2 GPUs is, rather famously, written in Rust, but it has achieved conformance with various graphics standards, which is also noteworthy. At the X.Org Developers Conference (XDC) 2024, Alyssa Rosenzweig gave an update on the status of the driver, along with some news about the kinds of games it can support (YouTube video, slides). There has...
