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 BPF program is safe is based on the whole lifetime of the program, instead of simple local factors, means that the cause of a verification
failure is not always obvious. Ihor Solodrai and Jordan Rome gave a presentation
(slides)
at the
2025 Linux Plumbers Conference in Tokyo about
the
BPF verifier visualizer that they have been building
to make diagnosing verification failures easier.
