WebBPF Kernel Functions (kfuncs) ¶ 1. Introduction ¶ BPF Kernel Functions or more commonly known as kfuncs are functions in the Linux kernel which are exposed for use by BPF programs. Unlike normal BPF helpers, kfuncs do not have a stable interface and can change from one kernel release to another.

WebThe safety of the eBPF program is determined in two steps. First step does DAG check to disallow loops and other CFG validation. In particular it will detect programs that have unreachable instructions. (though classic BPF checker allows them) Second step starts from the first insn and descends all possible paths.
