Linux Weekly News

BPF programs are loaded directly into the kernel. Even though the verifier protects the kernel from certain kinds of misbehavior in BPF programs, some people are still justifiably concerned about adding unsigned code to their kernel. A fully correct BPF program can still be used to expose sensitive data, for example. To remedy this, Blaise Boscaccy and KP Singh have both shared patch sets that add ways to verify cryptographic signatures of BPF programs, allowing users to configure their kernels to load only pre-approved BPF programs. This work follows on from the discussion at the Linux Storage, Filesystem, Memory-Management, and BPF Summit (LSFMM+BPF) in April and Boscaccy's earlier proposal of a Linux Security Module (LSM) to accomplish the same goal. There are still some fundamental disagreements over the best approach to signing BPF programs, however.

The Arch Linux project is especially well-known in the Linux community for two things: its rolling-release model and the quality of the documentation in the ArchWiki. No matter which Linux distribution one uses, the odds are that eventually the ArchWiki's documentation will prove useful. The Debian project recognized this and has sought to improve its own documentation game by inviting ArchWiki maintainers Jakub Klinkovský and Vladimir Lavallade to DebConf25 in Brest, France, to speak about how Arch manages its wiki. The talk has already borne fruit with the launch of an effort to revamp the Debian wiki.

Version 1.3.0 of the Radicle distributed software forge system has been released. Changes this time around include canonical references, a new radicle-protocol crate, better log rotation, and more. (LWN looked at Radicle in 2024).

Security updates have been issued by AlmaLinux (kernel, kernel-rt, and python-requests), Debian (ca-certificates-java), Fedora (chromium, clash-meta, mingw-python3, openjpeg, php-adodb, and toolbox), Mageia (kernel and kernel-linus), SUSE (chromium, ImageMagick, libgcrypt, libssh, libxml2, opensc, postgresql14, and postgresql16), and Ubuntu (dnsmasq, linux-gcp-6.8, linux-raspi, linux-oracle-6.14, and openjdk-17).

Debian's GNU/Hurd team has announced the release of Debian GNU/Hurd 2025:

This is a snapshot of Debian "sid" at the time of the stable Debian "Trixie" release (August 2025), so it is mostly based on the same sources. It is not an official Debian release, but it is an official Debian GNU/Hurd port release. [...]

Debian GNU/Hurd is currently available for the i386 and amd64 architectures with about 72% of the Debian archive, and more to come!

See the FAQ and configuration guide for more on the GNU/Hurd port.

Richard Hughes, creator and maintainer of the Linux Vendor Firmware Service (LVFS), has written a blog post about the sustainability plan he has put together for the service. He is calling for the vendors that use the service to help fund its development and maintenance going forward. The Linux Foundation is kindly paying for all the hosting costs of the LVFS, and Red Hat pays for all my time — but as LVFS grows and grows that's going to be less and less sustainable longer term. We're trying to find funding to hire additional resources as a "me replacement" so that there is backup and additional attention to LVFS (and so that I can go on holiday for two weeks without needing to take a laptop with me).

This year there will be a fair-use quota introduced, with different sponsorship levels having a different quota allowance. Nothing currently happens if the quota is exceeded, although there will be additional warnings asking the vendor to contribute. The "associate" (free) quota is also generous, with 50,000 monthly downloads and 50 monthly uploads. This means that almost all the 140 vendors on the LVFS should expect no changes.

(Thanks to Paul Wise.)

StarDict is a GPLv3-licensed cross-platform dictionary application. It includes dictionaries for a number of languages, and has a rich plugin ecosystem. It also has a glaring security problem: while running on X11, using Debian's default configuration, it will send a user's text selections over unencrypted HTTP to two remote servers.

The 6.17-rc1 prepatch was released by Linus Torvalds on August 10; the 6.17 merge window is now closed. There were 11,404 non-merge changesets pulled into the mainline this time around, a little over 7,000 of which came in after the first-half merge-window summary was written. As one would expect, quite a few changes and new features were included in that work.

Security updates have been issued by AlmaLinux (jackson-annotations, jackson-core, jackson-databind, jackson-jaxrs-providers, and jackson-modules-base and libxml2), Debian (distro-info-data, gnutls28, modsecurity-crs, and node-tmp), Fedora (chromium, incus, perl, perl-Devel-Cover, perl-PAR-Packer, polymake, varnish, and xen), Red Hat (kernel, kernel-rt, and rhc), and SUSE (chromedriver, ffmpeg-4, go1.23, go1.24, go1.25, govulncheck-vulndb, himmelblau, iperf, keylime-ima-policy, net-tools, sqlite3, texmaker, tomcat, and zabbix).
