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?

-       return strcmp(sec_name, sec_def->sec) == 0;
+       return strncmp(sec_name, sec_def->sec, len) == 0;
 }
