ICANN's Security and Stability Advisory Committee (SSAC) has announced a report on "the critical role of Free and Open Source Software (FOSS) within the Domain Name System (DNS)". The report is aimed at policymakers and examines recent cybersecurity regulations in the US, UK, and EU as they apply to FOSS in the DNS system; it includes findings and guidelines "to strengthen the FOSS ecosystem that is critical to the secure and stable operation of the Internet". From the report's summary:

This ecosystem depends on a global network of maintainers and contributors who are often unpaid volunteers. While many are unpaid volunteers, the DNS space is unique in also relying on a handful of long-lived maintenance organizations. This creates a model based on community collaboration rather than the commercial contracts that define a traditional software supply chain, which introduces unique risks related to financial sustainability for the maintenance organizations and maintainer burnout for volunteers.

These unique characteristics mean that regulatory frameworks designed for proprietary software may not be well-suited for FOSS and therefore could have severe unintended consequences to the stability of critical Internet infrastructure.

Thanks to SSAC member Maarten Aertsen for the tip.

Version 15.0 of the Tor Browser has been released:

This is our first stable release based on Firefox ESR 140, incorporating a year's worth of changes that have been shipped upstream in Firefox. As part of this process, we've also completed our annual ESR transition audit, where we reviewed and addressed around 200 Bugzilla issues for changes in Firefox that may negatively affect the privacy and security of Tor Browser users. Our final reports from this audit are now available in the tor-browser-spec repository on our GitLab instance.

This release inherits the vertical tabs feature, unified search button, as well as other new features and usability improvements in Firefox that have passed the Tor Project's audit.

Debian's ftpmaster team has been responsible for allowing new packages to enter Debian, removing old packages, and otherwise maintaining Debian's package archive for more than two decades. As of October 26, the team is no more and its duties are being split between two new teams. The Archive Operations Team will focus on the infrastructure required to support the Debian archives, and the DFSG, Licensing & New Packages Team, which is responsible for reviewing packages entering the new queue. In time, this move could speed up processing of new packages, as well as making the teams more sustainable, but only after new members are recruited and trained. For now, the same folks are doing the work but spread across two teams.

Fil-C is a memory-safe implementation of C and C++ that aims to let C code — complete with pointer arithmetic, unions, and other features that are often cited as a problem for memory-safe languages — run safely, unmodified. Its dedication to being "fanatically compatible" makes it an attractive choice for retrofitting memory-safety into existing applications. Despite the project's relative youth and single active contributor, Fil-C is capable of compiling an entire memory-safe Linux user space (based on Linux From Scratch), albeit with some modifications to the more complex programs. It also features memory-safe signal handling and a concurrent garbage collector.

The Fedora Project has announced the release of Fedora Linux 43, with "what's new" articles for Fedora Workstation, Fedora KDE Plasma Desktop, and Fedora Atomic Desktops.

For those of you installing fresh Fedora Linux 43 Spins, you may be greeted with the new Anaconda WebUI. This was the default installer interface for Fedora Workstation 42, and now it's the default installer UI for the Spins as well.

If you are a GNOME desktop user, you'll also notice that the GNOME is now Wayland-only in Fedora Linux 43. GNOME upstream has deprecated X11 support, and has disabled it as a compile time default in GNOME 49. Upstream GNOME plans to fully remove X11 support in GNOME 50.

See the release notes for a full list of changes in Fedora 43.

BPF lets users load programs into a running kernel. Even though BPF programs are checked by the verifier to ensure that they stay inside certain limits, some users would still like to ensure that only approved BPF programs are loaded. KP Singh's patches adding that capability to the kernel were accepted in version 6.18, but not everyone is satisfied with his implementation. Blaise Boscaccy, who has been working to get a version of BPF code signing with better auditability into the kernel for some time, posted a patch set on top of Singh's changes that alters the loading process to not invoke security module hooks until the entire loading process is complete. The discussion on the patch set is the continuation of a long-running disagreement over the interface for signed BPF programs.

We're disappointed to have been put in the position where we had to make this decision, because we believe our proposed project would offer invaluable advances to the Python and greater open source community, protecting millions of PyPI users from attempted supply-chain attacks. The proposed project would create new tools for automated proactive review of all packages uploaded to PyPI, rather than the current process of reactive-only review.

Version 0.3.0 of Rust Coreutils, part of the uutils project, has been released. This release adds safe directory traversal for several utilities, better error handling, and performance improvements. The project has upgraded its test suite reference from GNU coreutils 9.7 to 9.8, and added 16 new tests. It includes a fix for the date bug that affected automatic updates in Ubuntu 25.10.

Version 3.26.0 of the Valgrind memory-profiling and debugging framework has been released. Notable changes include updated support for the Linux Test Project (LTP) to version v20250930, many new Linux syscall wrappers, and the license for Valgrind has been changed from GPLv2 to GPLv3.

If you need to comply with accessibility-related regulations, Typst 0.14 has your back. Typst now generates accessible documents by default, with opt-in support for stricter checks. For those working with complex illustrations, PDFs are now supported as a native image format. In case you're typesetting a book, the new character-level justification will give your layout the final touch. And if you're building a website or blog, many improvements to Typst's HTML export are waiting for you.

LWN looked at Typst in September.

Open-source foundations and projects that have charity status in the US may want to see if GoFundMe has created a profile for them without permission. The company has operated since 2010 as a self-service fundraising platform; individuals or groups could create pages to raise money for all manner of causes. In June, the company announced that it would expand its offerings to "manage all aspects of charitable giving" for users through its platform. That seems to include creating profiles for nonprofit organizations without their involvement. After pushback, the company said on October 23 that it would be removing the pages. It has not answered more fundamental questions about how it planned to disburse funds to nonprofits that had no awareness of the GoFundMe pages in the first place.

The Ubuntu Project has announced that a bug in the Rust-based uutils version of the date command shipped with Ubuntu 25.10 broke automatic updates:

Some Ubuntu 25.10 systems have been unable to automatically check for available software updates. Affected machines include cloud deployments, container images, Ubuntu Desktop and Ubuntu Server installs.

The announcement includes remediation instructions for those affected by the bug. Systems with the rust-coreutils package version 0.2.2-0ubuntu2 or earlier have the bug, it is fixed in 0.2.2-0ubuntu2.1 or later. It does not impact manual updates using the apt command or other utilities.

Ubuntu embarked on a project to "oxidize" the distribution by switching to uutils and sudo-rs for the 25.10 release, and to see if the Rust-based utilities would be suitable for the long-term-release slated for next April. LWN covered that project in March.

Greg Kroah-Hartman has released the 6.17.5, 6.12.55, and 6.6.114 stable kernels. As usual, each contains important fixes throughout the tree; users are advised to upgrade.
