In early March, Dylan M. Taylor submitted a pull request to add a field to store a user's birth date in systemd's JSON user records. This was done to allow applications to store the date to facilitate compliance with age-attestation and -verification laws. It was to be expected that some members of the community would object; the actual response, however, has been shockingly hostile. Some of this has been fueled by a misinformation campaign that has targeted the systemd project and Taylor specifically, resulting in Taylor being doxxed and receiving death threats. Such behavior is not just problematic; it is also deeply misguided given the actual nature of the changes.

There is a blog post on sockpuppet.org arguing that we are not prepared for the upcoming flood of high-quality, LLM-generated vulnerability reports and exploits.

Now consider the poor open source developers who, for the last 18 months, have complained about a torrent of slop vulnerability reports. I'd had mixed sympathies, but the complaints were at least empirically correct. That could change real fast. The new models find real stuff. Forget the slop; will projects be able to keep up with a steady feed of verified, reproducible, reliably-exploitable sev:hi vulnerabilities? That's what's coming down the pipe.

Everything is up in the air. The industry is sold on memory-safe software, but the shift is slow going. We've bought time with sandboxing and attack surface restriction. How well will these countermeasures hold up? A 4 layer system of sandboxes, kernels, hypervisors, and IPC schemes are, to an agent, an iterated version of the same problem. Agents will generate full-chain exploits, and they will do so soon.

Meanwhile, no defense looks flimsier now than closed source code. Reversing was already mostly a speed-bump even for entry-level teams, who lift binaries into IR or decompile them all the way back to source. Agents can do this too, but they can also reason directly from assembly. If you want a problem better suited to LLMs than bug hunting, program translation is a good place to start.

SystemRescue 13.00 has been released. The SystemRescue distribution is a live boot system-rescue toolkit, based on Arch Linux, for repairing systems in the event of a crash. This release includes the 6.18.20 LTS kernel, updates bcachefs tools and kernel module to 1.37.3, and many upgraded packages. See the step-by-step guide for instructions on performing common operations such as recovering files, creating disk clones, and resetting lost passwords.

Version 4.0.0 of the Rspamd spam-filtering system has been released. Notable new features include HTML fuzzy phishing detection, support for up to eight flags with fuzzy hashes, and more. See the changelog for more on improvements, breaking changes, and bug fixes.

Rust's compiler team has been working on a long-term project to rewrite the trait solver — the part of the compiler that determines which concrete function should be called when a programmer uses a trait method that is implemented for multiple types. The rewrite is intended to simplify future changes to the trait system, fix a handful of tricky soundness bugs, and provide faster compile times. It's also nearly finished, with a relatively small number of remaining blocking bugs.

The 7.0-rc6 kernel prepatch is out for testing.

Anyway, exactly because it's just "more than usual" rather than feeling *worse* than usual, I don't currently feel this merits extending the release, and I still hope that next weekend will be the last rc. But it's just a bit unnerving how this release doesn't want to calm down, so no promises.

LiteLLM is a gateway library providing access to a number of large language models (LLMs); it is popular and widely used. On March 24, the word went out that the version of LiteLLM found in the Python Package Index (PyPI) repository had been compromised with information-stealing malware and downloaded thousands of times, sparking concern across the net. This may look like just another supply-chain attack — and it is — but the way it came about reveals just how many weak links there are in the software supply chains that we all depend on.

The SafeDep blog reports that compromised versions of the telnyx package have been found in the PyPI repository:

Two versions of telnyx (4.87.1 and 4.87.2) published to PyPI on March 27, 2026 contain malicious code injected into telnyx/_client.py. The telnyx package averages over 1 million downloads per month (~30,000/day), making this a high-impact supply chain compromise. The payload downloads a second-stage binary hidden inside WAV audio files from a remote server, then either drops a persistent executable on Windows or harvests credentials on Linux/macOS.

Greg Kroah-Hartman has announced the release of the 6.12.79 stable kernel. This release only reverts a patch that caused a regression on the LoongArch platform; users who could not build 6.12.78 on LoongArch need to upgrade.

Security updates have been issued by AlmaLinux (389-ds:1.4, gnutls, mysql:8.0, mysql:8.4, nginx, nginx:1.24, opencryptoki, python3, vim, and virt:rhel and virt-devel:rhel), Debian (firefox-esr, ruby-rack, and thunderbird), Fedora (fontforge, headscale, kryoptic, libopenmpt, pyOpenSSL, python-cryptography, rubygem-json, rust-asn1, rust-asn1_derive, rust-cryptoki, rust-cryptoki-sys, rust-wycheproof, vim, and vtk), Oracle (freerdp, golang, mysql:8.0, and ncurses), Red Hat (osbuild-composer), Slackware (libpng and tigervnc), SUSE (chromium, frr, kea, kernel, nghttp2, pgvector, python-deepdiff, python-pyasn1, python-tornado6, python-urllib3, python3, python310, ruby2.5, salt, sqlite3, systemd, tomcat, vim, and xen), and Ubuntu (libcryptx-perl).

Tomáš Hrčka has announced that the Forgejo-based Fedora Forge is now a fully operational collaborative-development platform; it is ready for use by the larger Fedora community, which means the homegrown Pagure platform's days are numbered:

While pagure.io has been a vital part of our community for many years, the time has come to retire our homegrown forge and transition to this powerful new tool.

The final cutover is planned for Flock to Fedora 2026. We strongly encourage teams to migrate their projects well before the conference to ensure a smooth transition. The pagure.io migration is only the first step in a broader infrastructure modernization effort. By the 2027 Fedora 46 release, we plan to retire all remaining Pagure instances across the project, including the package source repositories on src.fedoraproject.org. Getting familiar with Fedora Forge now will help ensure your team is ready as the rest of the Fedora ecosystem transitions.

There is a migration guide for Fedora community members that own projects hosted on Pagure and need to move to the new forge.

A number of projects have been struggling with the question of which submissions created by large language models (LLMs), if any, should be accepted into their code base. This discussion has been further muddied by efforts to use LLM-driven reimplemention as a way to remove copyleft restrictions from a body of existing code, as recently happened with the Python chardet module. In this context, an attempt to introduce an LLM-generated implementation of the Linux ext4 filesystem into OpenBSD was always going to create some fireworks, but that project has its own, clearly defined reasons for looking askance at such submissions.
