From bulletproof backpacks to banning file downloads: why our fight against 3D printed guns keeps missing the point—and what policy leaders should really be asking.

The post Dear Mr. District Attorney, Fight 3D Printed Guns the Right Way appeared first on Linux Today.

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.
