What have been the most significant security-related incidents for the open-source community in 2024 (so far)? Marta Rybczyńska recently ran a poll and got some interesting results. At the 2024 Open Source Summit Japan, she presented those results along with some commentary of her own. The events in question are unlikely to be a surprise to LWN readers, but the overall picture that was...

Longtime Debian and Tor developer, Jérémy Bobbio—perhaps better known as "Lunar"—died on November 8. Lunar was one of the founders of the reproducible builds movement and more recently had been working with Software Heritage. More information and tributes in French can be found at this site. They will be missed.

Linus has released 6.12-rc7 for testing. "No big surprises, and I think everything is on track for a final 6.12 release next weekend."

Back In Time is a GPL-2.0-licensed backup tool based on rsync and written in Python. It has both graphical and command-line interfaces, and supports backups to local disks or over SSH. Back In Time was originally written by Oprea Dan and released in 2009. The tool has been through some rough patches over the years, and is currently on its third set of maintainers....

Greg Kroah-Hartman has shared another seven stable kernel updates: 6.6.60, 6.11.7, 6.1.116, 5.15.171, 5.10.229, 5.4.285, and 4.19.323.

Fedora Linux, as a rule, handles version upgrades reasonably well. However, there are times when users may want to do a fresh installation rather than an upgrade but preserve existing users and data under /home. This is a scenario that the Fedora installer, currently, does not address. Users can maintain a separate /home partition, of course, but the installer does not incorporate existing users...

Arthur Cohen has posted a detailed introduction to the gccrs project on the Rust Blog, seemingly with the goal of convincing the Rust community about the value of the project. Likewise, many GCC plugins are used for increasing the safety of critical projects such as the Linux kernel, which has recently gained support for the Rust programming language. This makes gccrs a useful tool...

Security updates have been issued by AlmaLinux (edk2), Debian (webkit2gtk), Fedora (thunderbird), Oracle (bzip2, container-tools:ol8, edk2, go-toolset:ol8, libtiff, python-idna, python3.11, and python3.12), Slackware (expat), and SUSE (apache2, govulncheck-vulndb, grub2, java-1_8_0-openjdk, python3, python39, qemu, xorg-x11-server, and xwayland).

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...

Security updates have been issued by AlmaLinux (bcc, bpftrace, bzip2, container-tools:rhel8, grafana-pcp, haproxy, kernel, kernel-rt, krb5, libtiff, python-gevent, python3.11, python3.11-urllib3, python3.12, python3.12-urllib3, xmlrpc-c, and xorg-x11-server and xorg-x11-server-Xwayland), Debian (puma and pypy3), Fedora (firefox), Gentoo (libgit2), Mageia (libarchive), SUSE (ghostscript, go1.22-openssl, go1.23-openssl, htmldoc, kmail-account-wizard, libarchive, libgsf, libmozjs-128-0, openssl-3, python-jupyterlab, python-mysql-connector-python, python36, and ruby2.1), and Ubuntu (cinder, linux-aws, linux-aws-6.8, linux-oracle, linux-oracle-6.8, linux-aws, linux-azure-5.4, linux-kvm, linux-oracle, linux-xilinx-zynqmp,...

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...
