Linux Weekly News

The calendar has flipped over to 2026; a new year has begun. That means the moment we all dread has arrived: it is time for LWN to put out a set of lame predictions for what may happen in the coming year. Needless to say, we do not know any more than anybody else, but that doesn't stop us from making authoritative-sounding pronouncements anyway.

Version 1.30 of the GNU ddrescue data recovery tool has been released. Notable changes in this release include improvements to automatic recovery of a drive with a dead head, addition of a --no-sweep option to disable reading of skipped areas, and more.

Security updates have been issued by AlmaLinux (tar), Debian (curl and gimp), Fedora (doctl, gitleaks, gnupg2, grpcurl, nginx, nginx-mod-brotli, nginx-mod-fancyindex, nginx-mod-headers-more, nginx-mod-modsecurity, nginx-mod-naxsi, nginx-mod-vts, and usd), Mageia (cups), Red Hat (container-tools:rhel8, go-toolset:rhel8, grafana, and skopeo), and SUSE (dirmngr, fluidsynth, gnu-recutils, libmatio-devel, python311-marshmallow, python312-Django6, rsync, and thunderbird).

The 6.19-rc4 kernel prepatch is out for testing.

So this rc is still a bit smaller than usual, but it's not _much_ smaller, and I think next week is likely going to be more or less back to normal.

Which is all exactly as expected, and nothing here looks particularly odd. I'll make an rc8 this release just because of the time lost to the holidays, not because it looks like we'd have any particular issues pending (knock wood).

Greg Kroah-Hartman has written an overview of how the kernel's security team works.

The members of the security team contain a handful of core kernel developers that have experience dealing with security bugs, and represent different major subsystems of the kernel. They do this work as individuals, and specifically can NOT tell their employer, or anyone else, anything that is discussed on the security alias before it is resolved. This arrangement has allowed the kernel security team to remain independent and continue to operate across the different governments that the members operate in, and it looks to become the normal way project security teams work with the advent of the European Union's new CRA law coming into effect.

Greg Kroah-Hartman has announced the release of the 6.18.3 stable kernel. As always, this update contains important fixes; users of this kernel are advised to upgrade.

Security updates have been issued by Debian (smb4k), Fedora (direwolf, gh, usd, and webkitgtk), Slackware (libpcap and seamonkey), and SUSE (kepler).

Security updates have been issued by Debian (imagemagick and net-snmp), Fedora (delve, golang-github-google-wire, and golang-github-googlecloudplatform-cloudsql-proxy), and SUSE (podman, python3, and python36).

Version 4.19.0 of the shadow-utils project has been released. Notable changes in this release include disallowing some usernames that were previously accepted with the --badname option, and removing support for escaped newlines in configuration files. Possibly more interesting is the announcement that the project is deprecating a number of programs, hashing algorithms, and the ability to periodically expire passwords:

Scientific research shows that periodic password expiration leads to predictable password patterns, and that even in a theoretical scenario where that wouldn't happen the gains in security are mathematically negligible (paper link).

Modern security standards, such as NIST SP 800-63B-4 in the USA, prohibit periodic password expiration. [...]

To align with these, we're deprecating the ability to periodically expire passwords. The specifics and long-term roadmap are currently being discussed, and we invite feedback from users, particularly from those in regulated environments. See #1432.

The release announcement notes that the features will remain functional "for a significant period" to minimize disruption.

Security updates have been issued by Debian (mediawiki), Fedora (duc, golang-github-projectdiscovery-mapcidr, and kustomize), Slackware (wget2), and SUSE (cheat, duc, flannel, go-sendxmpp, python311, python312, python313, and trivy).

Daniel Stenberg has written a blog post about the decision to ban the use strcpy() in curl:

The main challenge with strcpy is that when using it we do not specify the length of the target buffer nor of the source string. [...]

To make sure that the size checks cannot be separated from the copy itself we introduced a string copy replacement function the other day that takes the target buffer, target size, source buffer and source string length as arguments and only if the copy can be made and the null terminator also fits there, the operation is done.

Security updates have been issued by Debian (openjpeg2, osslsigncode, php-dompdf, and python-django), Fedora (fluidsynth, golang-github-alecthomas-chroma-2, golang-github-evanw-esbuild, golang-github-jwt-5, and opentofu), Mageia (ceph and ruby-rack), and SUSE (anubis, apache2-mod_auth_openidc, dpdk22, kernel, libpng16, and python311-openapi-core).

Nate Graham looks back at how 2025 went for the KDE project.

Today Plasma is the default desktop environment in a bunch of the hottest new gaming-focused distros, including Bazzite, CachyOS, Garuda, Nobara, and of course SteamOS on Valve's gaming devices. Fedora's Plasma edition was also promoted to co-equal status with the GNOME edition, and Asahi Linux — the single practical option for Linux on newer Macs — only supports KDE Plasma. Parrot Linux recently switched to Plasma by default, too. And Plasma remains the default on old standbys like EndeavourOS, Manjaro, NixOS, OpenMandriva, Slackware and TuxedoOS — which ships on all devices sold by Tuxedo Computers!

Security updates have been issued by Debian (kodi, pgbouncer, and rails), Fedora (duc, fluidsynth, gdu, singularity-ce, and tkimg), Slackware (vim), and SUSE (buildah, duc, gnutls, python39, qemu, and webkit2gtk3).

Linus has released 6.19-rc3 for testing. "Another week, another -rc release. Except the past week has obviously been the holiday week, and this rc release is pretty small as a result. Very much as expected."

Graphite is an effort to unify illustration, raster editing, desktop publishing, and animation in one browser-based application. The project has been in development since 2020 and announced its first alpha release in 2022. According to creator Keavon Chambers, the project's mission is to become "the 2D counterpart to Blender", by bringing a node-based, non-destructive workflow to 2D graphics. The project, currently still in alpha, is a long way from complete; but it is worth testing for anyone involved with open-source-graphics production. Current builds, from September 2025, include vector-illustration tools, a node-based compositor, and early brush tooling, with broader pixel-based- and photo-editing work still in progress.

Security updates have been issued by Debian (gst-plugins-good1.0, postgresql-13, and python-urllib3), Fedora (chezmoi, docker-buildkit, ov, and subfinder), Oracle (httpd:2.4), Slackware (net), and SUSE (apache2, buildah, kernel, and mariadb).

The judge in the Vizio GPL-compliance lawsuit has ruled, in a summary judgment, that the GNU General Public License, version 2, does not require the provision of signing keys needed to install modified software on a device.

Read as a whole, the Agreements require Vizio to make the source code available in such a manner that the source code can be readily obtained and modified by Plaintiff or other third parties. While source code is defined to include "the scripts used to control compilation and installation," this does not mean that Vizio must allow users to reinstall the software, modified or otherwise, back onto its smart TVs in a manner that preserves all features of the original program and/or ensures the smart TVs continue to function properly. Rather, in the context of the Agreements, the disputed language means that Vizio must provide the source code in a manner that allows the source code to be obtained and revised by Plaintiff or others for use in other applications.

As the Software Freedom Conservancy, the plaintiff in the case, has pointed out, the judge has ruled against a claim that was never actually made.

SFC has never held the position, nor do we today hold the position, that any version of the GPL (even including GPLv3!) require "that the device continues to function properly" after a user installs their modified version of the copyleft components.

Linus Torvalds, meanwhile, has posted his own take on the ruling that has, as one might imagine, sparked an extended discussion as well.

Once again there is a brand-new release under the tree from the Ruby programming-language project: Ruby 4.0 has been released with many new features and improvements. Notable changes include the experimental Ruby Box feature for in-process isolation of classes and modules, a new just-in-time compiler called ZJIT, and improvements to Ruby's parallel-execution mechanism (Ractor). There are a number of language changes as well. See the documentation for Ruby 4.0 for more.

Security updates have been issued by Fedora (httpd, retroarch, and roundcubemail), Oracle (container-tools:rhel8, grafana, httpd, kernel, python3.12, python39:3.9, thunderbird, and uek-kernel), and SUSE (cheat, go-sendxmpp, and kernel).
