Security updates for Tuesday
The Open Home Foundation launches
We created the Open Home Foundation to fight for the fundamental principles of privacy, choice, and sustainability for smart homes. And every person who lives in one.Ahead of today, we've transferred over 240 projects, standards, drivers, and libraries—Home Assistant, ESPHome, Zigpy, Piper, Improv Wi-Fi, Wyoming, and so many more—to the Open Home Foundation. This is all about looking into the future. We've done this to create a bulwark against surveillance capitalism, the risk of buyout, and open-source projects becoming abandonware. To an extent, this protection extends even against our future selves—so that smart home users can continue to benefit for years, if not decades. No matter what comes.

[$] Linus and Dirk chat about AI, XZ, hardware, and more
One of the mainstays of the the Linux Foundation's Open Source Summit is the "fireside chat" (sans fire) between Linus Torvalds and Dirk Hohndel to discuss open source and Linux kernel topics of the day. On April 17, at Open Source Summit North America (OSSNA) in Seattle, Washington, they held with tradition and discussed a range of topics including proper whitespace parsing, security, and the current AI craze.
Hutterer: udev-hid-bpf: quickstart tooling to fix your HID devices with eBPF
eBPF was originally written for network packet filters but as of kernel v6.3 and thanks to Benjamin, we have BPF in the HID subsystem. HID actually lends itself really well to BPF because, well, we have a byte array and to fix our devices we need to do complicated things like "toggle that bit to zero" or "swap those two values".
See this article for more information on the BPF-HID mechanism.
Security updates for Monday
Kernel prepatch 6.9-rc5
But if you ignore those oddities, it all looks pretty normal and things appear fairly calm. Which is just as well, since the first part of the week I was on a quick trip to Seattle, and the second part of the week I've been doing a passable imitation of the Fontana di Trevi, except my medium is mucus.
[$] Weighted memory interleaving and new system calls
Gregory Price recently posted a patch set that adds support for weighted memory interleaving — allowing a process's memory to be distributed between non-uniform memory access (NUMA) nodes in a more controlled way. According to his performance measurements, the patch set could provide a significant improvement for computers with network-attached memory. The patch set also introduces new system calls and paves the way for future extensions intended to give processes more control over their own memory.
Security updates for Friday
[$] Gentoo bans AI-created contributions
Gentoo Council member Michał Górny posted
an RFC to the gentoo-dev mailing
list in late February about banning "'AI'-backed (LLM/GPT/whatever)
contributions
" to the Gentoo Linux project. Górny wrote that the spread of the
"AI bubble
" indicated a need for Gentoo to formally take a stand on AI
tools. After a lengthy discussion, the Gentoo Council voted
unanimously this week to adopt his proposal and ban contributions generated with AI/ML tools.

[$] Identifying dependencies used via dlopen()
The recent XZ backdoor has sparked a lot of discussion about how the open-source community links and packages software. One possible security improvement being discussed is changing how projects like systemd link to dynamic libraries that are only used for optional functionality: using dlopen() to load those libraries only when required. This could shrink the attack surface exposed by dependencies, but the approach is not without downsides — most prominently, it makes discovering which dynamic libraries a program depends on harder. On April 11, Lennart Poettering proposed one way to eliminate that problem in a systemd RFC on GitHub.
[$] Fedora 40 firms up for release
Fedora 40 Beta was released on March 26, and the final release is nearing completion. So far, the release is coming together nicely with major updates for GNOME, KDE Plasma, and the usual cavalcade of smaller updates and enhancements. As part of the release, the project also scuttled Delta RPMs and OpenSSL 1.1.
