The Linux Plumbers Conference blog has areport from the sched_ext microconference held in Prague.

There is not a broad selection of mature, open-source web-browser enginesfor Linux users. Most of the browsers available for Linux are based on one ofjust three projects: Chromium's Blink, Firefox'sGecko, or WebKit. A new entrant wouldgenerally be seen as a welcome alternative, but the recent campaign to push oneof the LLM-written Nordstjernen browsersinto Debian and Arch Linux has raised some questions aboutthe project's development and security processes.

The Redox OS project, which is aUnix-like microkernel-based operating system written in Rust, has published a report on the workthat it has done in the last year to implement io_uring-likeI/O.

Security updates have been issued by AlmaLinux (emacs, thunderbird, and xdg-dbus-proxy), Debian (bind9, openjdk-21, pdns, php-mongodb, and thunderbird), Fedora (brotli, chromium, clevis, eog, flatpak, ghostscript, kernel, libinstpatch, libreswan, mingw-freetype, mingw-gstreamer1, mingw-gstreamer1-plugins-bad-free, mingw-gstreamer1-plugins-base, mingw-gstreamer1-plugins-good, openssh, perl-Alien-Brotli, perl-DBI, python3.12, rust-onefetch, stargz-snapshotter, util-linux, and webkitgtk), Mageia (cifs-utils, libxml2, packages, perl-Cpanel-JSON-XS, perl-Text-CSV_XS, sogo, util-linux, and weechat), Oracle (brotli, firefox, flatpak, gcc-toolset-15-gcc, kernel, libreswan, nodejs:22, nodejs:24, python-urllib3, skopeo, and xdg-dbus-proxy), Slackware (proftpd), SUSE (azure-storage-azcopy, containerd, corepack24, grok-build, ImageMagick, libsoup-2_4-1, matrix-synapse, podman, psqlODBC, python, python-M2Crypto-doc, python-Twisted-doc, and xen), and Ubuntu (authd).

Peter Robinson has written a blog post aboutthe current state of Fedora support for RaspberryPi5devices. According to Robinson, the upcoming Fedora45 release willwork-with caveats-onall variants of the RaspberryPi Model5B; theComputeModule5 and Pi500+ are still works in progress.

Alexandre Courbot spends most of his time working on the kernel doing codereviews. Recently, he's been wondering about what the standards should be forwhen Rust code is allowed to panic, and how it should do error handling moregenerally. Unlike many of the other talks at Kangrejos 2026, his talk was notpresenting some existing work, but rather hoping to solicit opinions on thetopic from the assembled Rust for Linux developers. He brought along a collection of trickycases that he had run into recently to prompt discussion.

Security updates have been issued by AlmaLinux (bind, bind9.18, brotli, buildah, container-tools:4.0, container-tools:rhel8, firefox, flatpak, freeipmi, gcc, golang, grafana, httpd, kernel, kernel-rt, libreswan, libX11, lrzsz, nodejs:14, nodejs:18, oci-seccomp-bpf-hook, podman, python-urllib3, python3.9, python38:3.8 and python38-devel:3.8, skopeo, thunderbird, xorg-x11-server, and xz), Debian (inkscape, swupdate, thunderbird, and valkey), Fedora (brotli, dolphin, helix, kernel, libical, mingw-python3, nsd, perl-Alien-Brotli, perl-Plack, perl-Plack-Middleware-ReverseProxy, rust-dua-cli, rust-gengo-bin, rust-gitui, stgit, unshield, and webkitgtk), Mageia (evolution, freetype2, ghostscript, kronosnet, libde265, libical, libjxl, packages, perl-DBI, perl-ExtUtils-Typemaps-Default, perl-Imager, vim, and webkit2), Oracle (bind, bind9.18, brotli, buildah, ca-certificates, firefox, flatpak, freeipmi, grafana, httpd, kernel, libreswan, libX11, lrzsz, nodejs22, nodejs24, nodejs:22, oci-seccomp-bpf-hook, perl-DBI:1.641, perl:5.32, postfix, postgresql16-pgvector, postgresql18-pgvector, python3.9, skopeo, unbound, xorg-x11-server, and xz), Red Hat (grafana, grafana-pcp, python3.12-urllib3, and python3.14-urllib3), SUSE (ca-certificates-mozilla, chromium, gn, cifs-utils, containerd, cpupower, cyrus-sasl, gcc13, gcc7, go1.26, go1.27, google-osconfig-agent, kernel, kubernetes-old, libsoup, libX11, libXi, openssh, podman, python-nltk, python-PyJWT, python-social-auth-core, rekor, runc, suseconnect-ng, and unbound), and Ubuntu (brotli and nginx).

Python's experimentaljust-in-time (JIT) compiler, which was added to CPython in 2024 for the 3.13release,is on its way out. In June, the Python steering council announcedthat it was pausing work on the JIT in CPython's main branch until there was anaccepted Python EnhancementProposal (PEP) that addressed concerns about maintenance, compatibility, andset clear success metrics as well as a timeline for completion. After creatingPEP836 ("JIT Go Brrr: ThePath to a Supported JIT Compiler for CPython")to try to meet the council's request, and after months of discussion, theJIT maintainers have withdrawn the PEP. For now, it appears that development onthe once-promising project has come to an end.

Greg Kroah-Hartman has announced the release of the 7.2.13 and 6.18.59 stable kernels. Each contains a number offixes throughout the tree. Users are advised to upgrade.

Christian Brauner has announced that hehas merged supportfor writing leaf components of systemd in Rust. Rust will be used only for newleaf components, existing code is not being ported to Rust and nothing thatother components depend on is written in Rust.Brauner said that theproject would like to move forward with Rust support in core systemd, "butthere are several blockers in Rust's support for dynamic libraries whichprevents us from doing that without massively bloating every binary webuild". Assuming all goes well, it seems likely this work will appear in thesystemd v263 release expected in December.

Since the merge window for 7.4 opened, there have been 6,753 non-mergechangesets pulled into the mainline repository. Many more are expected,especially given the possibility that this merge window will be extended tothree weeks. Still, even this initial set brought in a number of new features,in addition to the continued general cleanups and security fixes that the kernelhas seen recently.

Memory has always been a scarce resource in computing systems, but theproblem seems to have worsened recently. In particular, the worldwideshortage of memory chips has led to a renewed focus by systems developerson reducing memory usage. During the memory-management microconference atthe 2026 Linux Plumbers Conference, WillDeacon discussed one specific consumer of memory that is beingre-examined: kernel stacks.

Security updates have been issued by AlmaLinux (buildah, expat, grafana, grafana-pcp, httpd, iperf3, openssh, php, php8.4, php:7.4, php:8.2, and php:8.3), Debian (aide, chromium, clamav, erlang, linux-6.12, roundcube, unbound, and webkit2gtk), Fedora (bind9-next, ca-certificates, clevis-pin-trustee, golang-x-mobile, knot-resolver, maradns, ntpsec, php, socat, and vlc), Mageia (golang, jq, msgpack, open-isns, perl-Mozilla-CA, roundcubemail, and sudo), Oracle (.NET 10.0, .NET 8.0, .NET 9.0, cockpit-files, cockpit-machines, fetchmail, glycin-loaders, golang, jackson-core, librsvg2, mariadb11.8, openexr, openssh, php, php8.4, php:7.4, php:8.2, php:8.3, postgresql:16, qt5-qtbase, rust-sequoia-sq, and xorg-x11-server-Xwayland), Red Hat (ca-certificates and opentelemetry-collector), SUSE (aliyun-cli, amazon-ecs-init, bcel, coreutils, cups-filters, cyrus-sasl, distribution, expat, firefox, go1.26, go1.26-openssl, go1.27, guava, mutt, nvidia-open-driver-G07-signed, p11-kit, php74, php8, podman, python-soupsieve, python313-datamodel-code-generator, python313-Django5, thunderbird, and webkit2gtk3), and Ubuntu (openvpn, python-tornado, and zlib).

Linus Torvalds rarely writes significant amounts of kernel code these days, sothe mergingof a 48-part patch series from him is an unusual event. This series,destined for the 7.4 kernel release, performs some long-delayed kernelcleanup by removing a couple of the primitives used to access user-space memoryfrom the kernel. What was once a best practice has long been superseded,but it can take time for such changes to work their way through a body ofcode this large.

Version2.8.0 of the KeePassXC password-management application has beenreleased.

There are several Rust features that kernel developers have been hoping tostabilize, but Josh Triplett wanted to describe all of the otherfeatures that the Rust project is currently working on. He spoke about the topicat Kangrejos 2026, leaving the assembled kernel developers with several ideasabout how to use these upcoming Rust features in the kernel.The features included refinements to the type system, small syntax improvements, and asmarter borrow checker.

Inside this week's LWN.net Weekly Edition:

The PHP Foundation has put out ablog entry explaining how the vulnerabilities disclosed today cameabout and why they took so long to fix.

The Node.js project hasreleaseda number of security updates to fix, among other vulnerabilities, aremote-code-execution bug affecting programs that use Brotli compression. And,in case any programmers who use compiled languages thought they could relax, themusl libc project has also announced anew vulnerability: anout-of-boundswrite that could potentially lead to remote code execution, although thathas not been demonstrated.

We last looked in on hash-based integritychecking for kernel modules just over a year and half ago. Since that time,the patchset has undergone multiple revisions. At the 2026 Linux Plumbers Conference(LPC), Thomas Weischuh described the need for kernel-module integrityguarantees while still providing reproducible builds, how his patches implement that, and some ideas for possiblefurther work.

The Collabora blog providesan update on Tyr, a driver for Arm Mali GPUs.

Nix flakes are anexperimental feature of the Nix package-managementtool designed to build projects in a more self-contained and reproducibleway. Despite the feature's experimental status, it has become increasinglypopular for open-source projects to publish flake.nix files that offerpredefined development environments and build automation even when thoserepositories may not offer an upstream package or module for the NixOS Linux distribution. AlthoughNix flakes have a complicated history, and the path for stabilization isuncertain, flakes can provide useful capabilities for projects that choose toinclude them.

The PHP project has published PHPversions 8.5.12,8.4.27, 8.3.36 and 8.2.35 to addresstwo critical vulnerabilities that could allow unauthenticated remote codeexecution.

Greg Kroah-Hartman has announced the release of the 7.2.12,6.18.58,6.12.114, and 6.6.160 stable kernels. Each contains a numberof important fixes; users are advised to upgrade.

The PHP security team has let it beknown that there is a high-stakes security update coming at14:00UTC on October21. "All PHP users are encouraged toprepare now so they can upgrade as soon as the release is available".Anybody running a PHP site probably needs to be prepared for this one.

Setuid (and setgid) binaries have long been a source of headaches, and securityvulnerabilities, on Linux systems. They are largely seen as something to beavoided; SUSE's security team, for example, forbidsthe inclusion of setuid or setgid binaries in packages unless they have beenreviewed and explicitly allowed. Thorsten Kukuk wants to go a step further anddisallow them entirely. At the 2026AllSystemsGo! conference, he spokeabout his work to disable setuid system-wide, as well as some of the hurdlesthat remain.

The work to support block sizes larger than the page size on XFS has beendifficult. Many users of XFS run stable kernels, which means that they aren't testingnew XFS code as it is released. That has made Daniel Gomez wonder whetheradopting Rust for some of the data structures underlying XFS, particularlyXArrays, could reduce the number of bugs lurking in the code. AtKangrejos 2026, he led a discussion about the potential problems with convertingXArray to Rust. The assembled kernel developers had a number of reasons to becautious about replacing the XArray code, but Gomez was determined to experimentwith the possibility, citing both security and performance improvements.

Mozilla has announcedthat it has received a report that private keys associated with eight eMudhra intermediate certificates havebeen compromised:

OpenBSD 8.0 has beenreleased. There are many new features, including the addition of hibernatesupport for arm64, an increase in the kernel virtual address space for amd64 to512GB, quite a few improvements for the qwx driver that supportsQualcommWiFi6 devices, and much more. See the full changelog fordetails.

Linus Torvalds releasedthe 7.3 kernel, at the end of the usual nine-week development cycle, onOctober18. This cycle, abundantly fueled by LLM-assistedcontributions, broke just about every record imaginable. As usual, we havecompiled some statistics showing how this release, which is expected to bethe next long-term-support (LTS) kernel, came together. Also included isan attempt to determine whether automated patch review is actually reducingthe number of bugs introduced into the kernel.

Rust has several ad-hoc mechanisms to allow user code to influence how thestandard library executes. For example, custom panic handlers and customallocators both involve registering functions that core standard library codeneeds to call. With more similar features planned,Jana Donszelmann spotted the developing pattern and put together ageneral solution, introducing a safer, checked analogue of C's weak symbollinking. At Kangrejos 2026, she explained how this new language feature works,and proposed using it to clean up the kernel's handling of integer overflows inRust code.

Linus Torvalds has released the 7.3kernel, as expected.

The GNOME Project has provided GNOMEOS for some time; until now, theproject only provided a "Nightly" edition that was built from the latest commitsand was aimed solely at GNOME developers. Adrian Vovk has now announcedthe release of GNOMEOSPreview, which is intended for a non-developer audience:

Self-referential structures that can be used without unsafe codehave posed a problem for Rust for years.There are many cases where a self-referential data structure is the elegantalgorithmic choice, but implementing it in accordance with Rust's lifetime rulesis all but impossible. At Kangrejos 2026, Gary Guo presented a clever solutionto the problem in the context of the kernel'spin_init crate, which helps with the creation of immovable data structures,typically for interoperability with C. Guo's changes could help remove most ofthe unsafe code related to lifetimes in theNova driver and, eventually, other Rust components.

The NFS network filesystem protocol has a long history on Unix-likeoperating systems (and beyond). NFS is still evolving, though, andimplementations need to keep up. At the 2026 Linux Plumbers Conference, NFS developerJeff Layton gave an overview of recent enhancements to the Linuximplementation, along with some hints for what will be coming in the nearfuture.

The resultsfrom the 2026 election for members of the Linux Foundation TechnicalAdvisory Board (TAB) have been announced. Kees Cook, Dave Hansen, MiguelOjeda, and Shuah Khan have all been re-elected, and Laurent Pinchart willbe joining the board.

Since Android's inception, the kernels it has used have divergedsignificantly from the mainline. While many of those differences have beenresolved over time, and the move to the generickernel image has helped to bring Android closer, current devices stillcarry a lot of out-of-tree changes. The preferred form for such changes isby way of vendorhooks. At the 2026 LinuxPlumbers Conference, Todd Kjos ran a fast-paced session in the Androidtrack to discuss vendor hooks and how they are used.

Inside this week's LWN.net Weekly Edition:

LTTng creator Mathieu Desnoyers seems abit trapped in something of a catch-22.At the 2026 Linux Plumbers Conference(LPC), he led a discussion on the problem he is having in trying tocollaborate with other tracing projects (e.g. ftrace, perf) in the kernel. Thefeedback he has gotten, both over the years and more recently, does notshow a path that would allow him to contribute the 21-year-oldGPLv2-licensed LTTng tracing framework, or, incrementally, features fromit, to the mainline kernel.
