Welcome to the LWN.net Weekly Edition for May 1, 2025
This edition contains the following feature content:
- The mystery of the Mailman 2 CVEs: the report of three vulnerabilities in the end-of-life Mailman 2 system led to concern — and to doubts about whether those vulnerabilities actually exist.
- Debian debates AI models and the DFSG: what should be required of a model-based system before it can be part of Debian?
- Some __nonstring__ turbulence: a broken 6.15-rc3 release leads to disagreement in the kernel community.
- Cache awareness for the CPU scheduler: trying to do a better job of keeping processes near their data.
- LSFMM+BPF 2025 coverage:
- Freezing filesystems for suspend: the system suspend/resume path lacks the ability to freeze and thaw filesystems; what would it take to add that functionality?
- Inline socket-local storage for BPF: BPF developers discuss changing the layout of BPF map information in the networking subsystem to reduce cache misses.
- Better debugging information for inline kernel functions: selectively inlined functions can be difficult to debug; perhaps enriching the kernel's BTF debugging information could help.
- How LWN is faring in 2025: navigating through stormy waters.
This week's edition also includes these inner pages:
- Brief items: Brief news items from throughout the community.
- Announcements: Newsletters, conferences, security updates, patches, and more.
