Subject: Fix ipv4/ipv6 resolving. When not using AF_INET, gethostbyname2_r tries to resolve... 
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=eeb61522b53ffd943268104a7019d62202865787;p=openwrt%2Fstaging%2Fnbd.git

Fix ipv4/ipv6 resolving. When not using AF_INET, gethostbyname2_r tries to resolve an ipv6 address from /etc/hosts using __get_hosts_byname_r, but with AF_INET instead of the supplied address family. This returns ipv4 addresses marked as ipv6 ones.
