Return EAI_AGAIN for AF_UNSPEC when herrno is TRY_AGAIN (BZ #16849)
|
|
|
|
|
|
|
|
|
|
getaddrinfo correctly returns EAI_AGAIN for AF_INET and AF_INET6
|
|
|
|
|
queries. For AF_UNSPEC however, an older change
|
|
|
|
|
(a682a1bf553b1efe4dbb03207fece5b719cec482) broke the check and due to
|
|
|
|
|
that the returned error was EAI_NONAME.
|
|
|
|
|
|
|
|
|
|
This patch fixes the check so that a non-authoritative not-found is
|
|
|
|
|
returned as EAI_AGAIN to the user instead of EAI_NONAME.
