Subject: [PATCH] BIO_lookup_ex: use AI_ADDRCONFIG only if explicit host name
|
||
|
|
is given
|
||
|
|
|
||
|
|
The flag only affects which record types are queried (A or AAAA, or
|
||
|
|
both), and when node is NULL, it prevents getaddrinfo returning the
|
||
|
|
right address associated with the loopback interface.
