Found and fixed (1). It looks like GnuTLS may have started adding random
padding to application data in some of the recent versions (or well,
something after the initial wpa_supplicant wrapper implementation) and
wpa_supplicant was not prepared on the TLS library using that much extra
padding which forced the messages to be truncated.
