Subject: Fix ipv4/ipv6 resolving.
X-Git-Url: https://git.archive.openwrt.org/?p=openwrt.git;a=commitdiff_plain;h=b871cf38ee081fab651dee95e7d3ff3ab4bdc27b

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.
