Description Erik Cederstrand 2012-10-09 23:30:06 UTC

Similar to the create_service() function, lookup_addresses() should fail if the value of res->ai_family is neither AF_INET of AF_INET6.

The base type for res->ai_family is int, so there is no constraint that the value is with AF_INET or AF_INET6.

Fix: See attached patch. Instead of "break;" in the default switch, fail like create_service() function does.
