Alexis Lothoré has been working to add support for the kernel's memory-access checker, KASAN, to just-in-time-compiled BPF code. He spoke about that work at the 2026 Linux Storage, Filesystem, Memory-Management, and BPF Summit. KASAN support is needed, he said, to help catch bugs in the BPF just-in-time (JIT) compiler. KASAN is a great tool for catching memory-management problems in the kernel, but only in code that can be monitored by it.

The Tor Project has announced that it is planning to actively stop supporting Tor 0.4.8 and earlier C Tor versions soon.

Usually, we try not to break existing releases, even if they are unsupported, unless we have a pretty good reason. In this case, we have several reasons. [...]

The most important reason is this: in 0.4.9, we have made some former fields in our directory data obsolete -- specifically, TAP onion keys and family lines. Removing these fields will let us save a great deal of client directory bandwidth for everyone. This, in turn, will make all Tor clients bootstrap a little faster, especially those on slow connections. But when we remove these fields, clients and relays running earlier versions of Tor will no longer work, since they expect the TAP onion keys to be present. Therefore, in order to deliver improved performance faster, we need to accelerate the date on which 0.4.8 will stop working.

The target sunset date is currently September 1, 2026, after which any version prior to Tor 0.4.9 will cease to work on the network. The first stable release in the 0.4.9.x series was announced in February 2026, and the Tor 0.4.8.x series reached end of life on June 1.

The GIMP project reports that GNOME contributor "balooii" has worked to package GIMP 0.54.1—released in 1996—as a Flatpak that will build and run on modern 64-bit Linux systems. This is a Motif-based version, and the same version that was used by Larry Ewing to create Tux.

While not likely to be useful for serious graphics work today, it should be interesting for users who would like to see what a 30-year-old version of GIMP was capable of.

Brian Tarricone has announced the first preview release of xfwl4, a Wayland compositor for the Xfce desktop environment.

After close to six months of work, I feel like it's ready to get some wider use, even though of course there will be bugs and missing features. Think of this as an alpha release. [...]

The end goal of xfwl4 is to behave as closely as possible to an Xfce desktop running on an X server. Ideally a user could switch between the two without even knowing there's a difference. In reality, of course, it won't be quite that seamless, and there's still more work to be done to get as close as possible to that ideal. This is a first solid cut at it, at the very least.

Systemd v261 has been released with a long list of changes, including a new cloud "Instance Metadata Service" (IMDS) subsystem, "boot secret" functionality for use on systems that lack a physical TPM, as well as support for the kernel's Live Update Orchestration (LUO) / Kexec Handover (KHO) systems when they are present and enabled. See the release notes for the full list of changes.

BPF programs can be used to extend many aspects the Linux kernel, but BPF programs must run to completion in the same context that they began. Kumar Kartikeya Dwivedi is working on changing that by allowing BPF programs to be expressed as coroutines. He spoke about his work at the 2026 Linux Storage, Filesystem, Memory-Management and BPF Summit. While still experimental, the change promises to make long-running BPF tasks significantly easier to write.

The Arch User Repository (AUR) has been subjected to a sustained attack recently. The attacker, or attackers, have spun up a series of new accounts then used them to adopt orphaned packages and push malicious updates that would install malware on users' systems. It is unclear how many users were compromised in the attack, but the maintainers were playing Whac-A-Mole for several days to respond to each newly compromised package. The project has turned off the AUR's new-user registration, for now, but it is unclear what its long-term response will be or if the AUR can be secured without major changes to its existing collaboration model.

Greg Kroah-Hartman has announced the release of the 7.1.1, 7.0.13, 6.18.36, 6.12.94, 6.6.143, 6.1.176, 5.15.210, and 5.10.259 stable kernels. As usual, each contains important fixes. Users are advised to upgrade.

The Software Freedom Conservancy (SFC) has announced the release of its recommendations for using LLM-backed generative AI systems for FOSS contributions. The recommendations were created by the SFC and volunteers from the free-software community.

The recommendations reflect the extremely difficult dilemmas that these systems pose for FOSS contributors. SFC and its volunteers understand that FOSS developers are approaching LLM-gen-AI from a variety of perspectives. The recommendations offer practical assistance to minimize the damage caused by using proprietary systems, whether FOSS contributors reject LLM-gen-AI or choose (voluntarily or by employer mandate) to use them.

These recommendations are best practices (but not definitions or requirements) that SFC and its volunteers formulated after careful study of the growing LLM-gen-AI use among FOSS contributors. SFC will follow these recommendations with a series of supporting materials, including documents, online tutorials, public Q&As, podcasts, and other community engagement. We will routinely refine our recommendations and continue to support FOSS contributors as they navigate this difficult landscape.

The headliner of this release is Collections, a way to create and share curated collections of profiles. Part of Mastodon's work ethos is our commitment to trust and safety, so we've put a lot of thought and care into the design of this feature to avoid some of the pitfalls and abuse people have experienced with similar features on other platforms, while focusing on its primary goal: Helping new users discover more of the Fediverse.

Other new features include support for subscribing to posts via email, the ability to generate a "year in review" post, accessibility improvements, and more.

How can cloud providers efficiently supply durable virtual block devices? Remote Direct Memory Access (RDMA) provides a way for servers in a cluster to share chunks of memory, but there still needs to be a protocol that operates on top of RDMA to provide the guarantees expected of a block device. The kernel's RDMA transport library (RTRS) provides a way to send messages via RDMA. I presented about two new components built on top of RTRS at the 2026 Linux Storage, Filesystem, Memory Management and BPF Summit: Reliable Multicast over RTRS (RMR) and Block device over RMR (BRMR). These modules, which I am working on with Jia Li, could be a way for cloud providers to expose durable block devices with as little overhead as possible. To accomplish that, however, we need some discussion and feedback from the community before sending the modules upstream.

The results are in for Fedora's F44 election cycle for seats on the Fedora Council, Fedora Engineering Steering Committee, Fedora Mindshare Committee, and EPEL Steering Committee.

Miro Hrončok and Aleksandra Fedorova have won seats on the council. Neal Gompa, Fabio Valentini, Michel Lind, Maxwell G, and Simon de Vlieger have been elected to FESCo. Samyak Jain, Akashdeep Dhar, Luis Bazan, and Mat Holmes have all been elected to the Mindshare Committee. The four candidates for the EPEL committee, Carl George, Diego Hererra, Jonathan Wright, and Troy Dawson were all automatically elected as there were an equal number of candidates and seats open. Congratulations to all the winners.
