With the addition of the syscall prog type we should now be able to see feature probe info for that prog type: $ bpftool feature probe kernel ... eBPF program_type syscall is available ... eBPF helpers supported for program type syscall: ... - bpf_sys_bpf - bpf_sys_close And for the link types, their names should aid in the output. Before: $ bpftool link show 50: type 7 prog 5042 bpf_cookie 0 pids vfsstat(394433) After: $ bpftool link show 57: perf_event prog 5058 bpf_cookie 0 pids vfsstat(394725) Milan Landaverde (3): bpf/bpftool: add syscall prog type bpf/bpftool: add missing link types bpf/bpftool: handle libbpf_probe_prog_type errors tools/bpf/bpftool/feature.c | 2 +- tools/bpf/bpftool/link.c | 2 ++ tools/bpf/bpftool/prog.c | 1 + 3 files changed, 4 insertions(+), 1 deletion(-) -- 2.32.0
