Compiling bpftool¶ bpftool is an essential tool around debugging and introspection of BPF programs and maps. It is part of the kernel tree and available under tools/bpf/bpftool/. Make sure to have cloned either the net or net-next kernel tree as described earlier. In order to build and install bpftool, the following steps are required: By default bpftool will create new maps as declared in the ELF object being loaded.
