Thanks for your reply, actually, i tried another method, which can solved this error, recognize "socket/xxx" as "socket". However, it maybe influence other BPF prog or not? What do you think the following patch? --- a/tools/lib/bpf/libbpf.c +++ b/tools/lib/bpf/libbpf.c @@ -8659,7 +8659,7 @@ static bool sec_def_matches(const struct bpf_sec_def *sec_def, const char *sec_n return false; } - return strcmp(sec_name, sec_def->sec) == 0; + return strncmp(sec_name, sec_def->sec, len) == 0; }
