[$] In search of a stable BPF verifier

Date:
Mon, 14 Apr 2025 14:47:53 +0000

Description:
BPF is, famously, not part of the kernel's promises of user-space stability. 
New
kernels can and do break existing BPF programs; the BPF developers try to
fix unintentional regressions as they happen, but the whole thing can be 
something of a bumpy
ride for users trying to deploy BPF programs across multiple kernel versions.
Shung-Hsi Yu and Daniel Xu had two different approaches to fixing the problem
that they presented at the 2025 Linux Storage, Filesystem,
Memory-Management, and BPF Summit.
