Version
146.0 of the Firefox web browser has been released. One feature of
particular interest to Linux users is that Firefox now natively
supports fractional scaled displays on Wayland. Firefox Labs has also
been made available to all users even if they opt out of telemetry or
participating in studies. “This means more experimental features
are now available to more people.“

This release also adds support for Module-Lattice-Based
Key-Encapsulation Mechanism (ML-KEM) for WebRTC. ML-KEM is
“believed to be secure against attackers with large quantum
computers“. See the release notes for all changes.

Today, the KDE Project released KDE Plasma 6.5.4 as the fourth maintenance update to the latest KDE Plasma 6.5 desktop environment series with more improvements and bug fixes.

For the past 15 years the Smatch static analysis tool has been routinely run for uncovering countless bugs within the Linux kernel. Dan Carpenter who authored Smatch and has been routinely analyzing the Linux kernel with it has authored more than 5,568 patches over the years to become one of the top bug fixers for the kernel. But his funding at Linaro has been cut and the project’s future now in question…

Last week saw the main set of block and IO_uring feature patches for the Linux 6.19 merge window but some additional block subsystem material was merged on Monday. There are various NVMe updates now merged plus enabling per-CPU BIO caching by default to help with file-system performance…

Since Showtime replaced Totem as the default video player of GNOME, the desktop has lacked thumbnail capabilities for audio and video files. But to address that defect, the Rust-based gst-thumbnailers project has been in development to leverage GStreamer and paired with Rust to provide safe thumbnail generation capabilities for audio and video content…

The newest Mesa 26.0-devel code as of today has landed initial support for Qualcomm Adreno Gen 8 graphics into the Freedreno Gallium3D driver. The Adreno Gen 8 graphics so far are most notably used by the new Snapdragon X2 Elite laptop SoC with its X2-85 GPU as well as the new Snapdragon 8 Elite Gen 5 with Adreno 840 graphics…

Ventoy 1.1.08, an open-source tool for creating a bootable USB drive to load multiple ISO files, now supports FreeBSD 15.0.

Beginning with the Linux 6.19 kernel, the hung task detector and system lock-up detector are now optionally able to provide greater insight into the issues by dumping additional system information. The new lockup_sys_info and hung_task_sys_info sysctl knobs were merged over as part of the pull requests managed by Andrew Morton…

Google engineers for the past number of months have been working on the Live Update Orchestrator as a new way of applying live Linux kernel updates. The Live Update Orchestrator “LUO” builds atop the Kexec Handover “KHO” functionality already within the kernel. Google has since been deplyoing LUO in their production environments for faster security updates to kernels, especially when involving VMs. LUO is now upstream in Linux 6.19…

The

Internet Engineering Task Force (IETF) is the standards body responsible
for the TLS encryption standard — which your browser is using right now
to allow you to read LWN.net. As part of its work to keep TLS secure, the IETF
has been entertaining

proposals to adopt “post-quantum” cryptography (that is,
cryptography that is not known to be easily broken by a quantum computer) for TLS
version 1.3. Discussion of the proposal has exposed a large disagreement between
participants who worried about weakened security and others who worried about
weakened marketability.

Meson 1.10 is out today as the newest feature release for this popular cross-platform build system…

Jon Seager, VP of engineering for Canonical, has announced
a plan to develop a universal Public Key Infrastructure tool called
upki:

Earlier this year, LWN featured an excellent article titled
“Linux’s missing CRL
infrastructure“. The article highlighted a number
of key issues surrounding traditional Public Key Infrastructure (PKI),
but critically noted how even the available measures are effectively
ignored by the majority of system-level software on Linux.

One of the motivators for the discussion is that the Online
Certificate Status Protocol (OCSP) will cease to be supported by Let’s
Encrypt. The remaining alternative is to use Certificate Revocation
Lists (CRLs), yet there is little or no support for managing (or even
querying) these lists in most Linux system utilities.

To solve this, I’m happy to share that in partnership with rustls
maintainers Dirkjan Ochtman
and Joe Birr-Pixton, we’re starting the
development of upki: a universal PKI tool. This project initially aims
to close the revocation gap through the combination of a new system
utility and eventual library support for common TLS/SSL libraries such
as OpenSSL, GnuTLS and rustls.

No code is available as of yet, but the announcement indicates that
upki will be available as an opt-in preview for
Ubuntu 26.04 LTS. Thanks to Dirjan Ochtman for the tip.
