But k[ret]probe expect pt_regs while BTF-enabled program ctx will be the same as raw_tp. kretprobe is indistinguishable from kprobe while BTF-enabled kretprobe will have access to retval while kprobe will not. Hence PROG_KPROBE type is not reusable and reusing PROG_RAW_TRACEPOINT no longer fits well. Hence introduce 'umbrella' prog type BPF_PROG_TYPE_TRACING that will cover different BTF-enabled tracing attach points. The changes make libbpf side cleaner as well. check_attach_btf_id() is cleaner too. ==================== Signed-off-by: Daniel Borkmann --- 06087114606c416892bd67c5fde9f0d498afb287
