The loopback address is not considered\n> for this case as valid as a configured address.  This flag is\n> useful on, for example, IPv4-only systems, to ensure that\n> getaddrinfo() does not return IPv6 socket addresses that would\n> always fail in connect(2) or bind(2).\n\nNote that the FreeBSD version of getaddrinfo(3) does not mention that\nthe loopback address is not considered a valid configured address.\n\nIt is desirable that binding to wildcard addresses (the default) also\nworks when no routable IP addresses are configured on the system. This\ncan be achieved by removing the AI_ADDRCONFIG flag.\n\nThe flag appears to have been set in order to optimize DNS query\ntraffic [1]. My testing however shows that no DNS querying takes place\nas a result of anything done in the wait_for_connections function, so I\nbelieve that this change has no performance impact.\n\n[1] https://fedoraproject.org/wiki/QA/Networking/NameResolution/ADDRCONFIG","shortMessageHtmlLink":"Don't use AI_ADDRCONFIG for bind addr translation"}}],"hasNextPage":false,"hasPreviousPage":false,"activityType":"all","actor":null,"timePeriod":"all","sort":"DESC","perPage":30,"cursor":"djE6ks8AAAAEJkOtoAA","startCursor":null,"endCursor":null}},"title":"Activity · imre-sidn/nsca"}
