-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.
