+From f381c118b2d4f7d914481d3cdc830ce41369b002 Mon Sep 17 00:00:00 2001
+From: Rich Felker <dalias@aerifal.cx>
+Date: Wed, 19 Sep 2018 18:03:22 -0400
+Subject: fix getaddrinfo regression with AI_ADDRCONFIG on some configurations
+
+despite not being documented to do so in the standard or Linux
+documentation, attempts to udp connect to 127.0.0.1 or ::1 generate
+EADDRNOTAVAIL when the loopback device is not configured and there is
+no default route for IPv6. this caused getaddrinfo with AI_ADDRCONFIG
+to fail with EAI_SYSTEM and EADDRNOTAVAIL on some no-IPv6
+configurations, rather than the intended behavior of detecting IPv6 as
+unsuppported and producing IPv4-only results.
+
+previously, only EAFNOSUPPORT was treated as unavailability of the
+address family being probed. instead, treat all errors related to
+inability to get an address or route as conclusive that the family
+being probed is unsupported, and only fail with EAI_SYSTEM on other
+errors.
+
+further improvements may be desirable, such as reporting EAI_AGAIN
+instead of EAI_SYSTEM for errors which are expected to be transient,
+but this patch should suffice to fix the serious regression.
