            Bug ID: 16849
           Summary: getaddrinfo returns EAI_NONAME instead of EAI_AGAIN
                    for network failures
           Product: glibc
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: network
          Assignee: siddhesh at redhat dot com
          Reporter: siddhesh at redhat dot com

When a DNS query fails due to a network failure, the failure is considered
transient for AF_INET and AF_INET6 lookups and hence EAI_AGAIN is returned. 
However, when the new AF_UNSPEC support was added (by using gethostbyname4_r),
the returned error is EAI_NONAME.

Patch coming up.
