commit 15729bef385211bc2a0497e2d53a45c45d677d2c
Author: Daiki Ueno <dueno at redhat.com>
Date:   Thu Jul 8 19:22:36 2021 +0200

    BIO_lookup_ex: use AI_ADDRCONFIG only if explicit host name is given
    
    The flag only affects which record types are queried via DNS (A or
    AAAA, or both).  When node is NULL and AF_UNSPEC is used, it prevents
    getaddrinfo returning the right address associated with the loopback
    interface.
