The eBPF in-kernel virtual machine is
approaching its tenth anniversary as part of Linux; it has grown into a
tool with many types of uses in the ecosystem. Alexei Starovoitov, who
was the creator of eBPF and did much of the development of it, especially
in the early going, gave the opening talk at
Linux
Security Summit Europe 2023 on the relationship between BPF and
security. In it, he related some interesting history, from a somewhat
different perspective than what is often described, he said. Among other
things, it shows how BPF
has been both a security problem and a security solution along the way.
