Jonathan Nobels 02e3c046aa net/dns: re-query system resolvers on no-upstream resolver failure on apple platforms (#12398) ... Fixes tailscale/corp#20677 On macOS sleep/wake, we're encountering a condition where reconfigure the network a little bit too quickly - before apple has set the nameservers for our interface. This results in a persistent condition where we have no upstream resolver and fail all forwarded DNS queries. No upstream nameservers is a legitimate configuration, and we have no (good) way of determining when Apple is ready - but if we need to forward a query, and we have no nameservers, then something has gone badly wrong and the network is very broken. A simple fix here is to simply inject a netMon event, which will go through the configuration dance again when we hit the SERVFAIL condition. Tested by artificially/randomly returning [] for the list of nameservers in the bespoke ipn-bridge code responsible for getting the nameservers.
