lib/libc/asr : getaddrinfo_async.c gethostnamadr_async.c
Log message:
Reject empty CNAMEs in gethostbyname(3) / getaddrinfo(3).
An empty string is arguably not a correct hostname (even though
res_hnok accepts it). More worrisome though is software not expecting
this and making mistakes. In practice this cannot happen unless the
resolver lies to us.
OK deraadt, jca
