The function tor_inet_aton accepts strings that include leading zeroes. For example, "010.010.010.010" is parsed as "10.10.10.10". This could potentially be a problem because "010.010.010.010" is obsolete notation for an _octal_ IP address. At least in glibc, inet_aton or getaddrinfo treats "010.010.010.010" as "8.8.8.8", whereas inet_ntop rejects it as invalid. **Trac**: **Username**: liberat
