Arnd Bergmann began his 2025 Linux Plumbers Conference session on the future of 32-bit support in the Linux kernel by saying that it was to be a followup to his September talk on the same topic. The focus this time, though, was on the kernel's 'high memory' abstraction, and...
The BPF verifier works, on a theoretical level, by considering every possible path that a BPF program could take. As a practical matter, however, it needs to do that in a reasonable amount of time. At the 2025 Linux Plumbers Conference, Mahé Tardy and Paul Chaignon gave a...

Ian Jackson (along with Sean Whitton) has posted a manifesto and status update to the effect that, since Git repositories have become the preferred method to distribute source, that is how Debian should be distributing its source packages. Everyone who interacts with...
At Open Source Summit Japan 2025, Erin McKean talked about the challenges to producing good project documentation, along with some tooling that can help guide the process toward success. It is a problem that many projects struggle with and one that her employer, Google,...
John Paul Adrian Glaubitz has announced that loong64 is now an official architecture for Debian, and will be part of the Debian 14 ('forky') release 'if everything goes along as planned'. This is a bit more than two years after the initial bootstrap of the architecture. So f...

The BPF verifier is complicated. It needs to check every possible path that a BPF program's execution could take. The fact that its determination of whether a BPF program is safe is based on the whole lifetime of the program, instead of simple local factors, means that the...
