inet_pton() included in src/lib/libc/net is not spec conformant.
inet_pton() must not allow shortened IPv4 addresses, like:
10 for 10.0.0.0
10.1 for 10.0.0.1
10.0.1 for 10.0.0.1
(see RFC2553 6.6) but the current code allows it.
What is the right thing to happen?
- fix it, some may react that "ftp 10.1" does not work
- leave it
Note that getaddrinfo() currently calls inet_pton() internally,
and changing behavior of inet_pton() will affect behavior of
telnet, ftp or whatever else. actually RFC2553 is silent about
getaddrinfo() behavior in this case (should/should not accept
