David Anderson	f6b7d08aea	net/dns: work around new NetworkManager in other selection paths. Further bits of #1788 Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	25ce9885a2	net/dns: don't use NM+resolved for NM >=1.26.6. NetworkManager fixed the bug that forced us to use NetworkManager if it's programming systemd-resolved, and in the same release also made NetworkManager ignore DNS settings provided for unmanaged interfaces... Which breaks what we used to do. So, with versions 1.26.6 and above, we MUST NOT use NetworkManager to indirectly program systemd-resolved, but thankfully we can talk to resolved directly and get the right outcome.

David Anderson	2685260ba1	net/dns: add temporary fallback to quad-9 resolver for split-DNS testing. This allows split-DNS configurations to not break clients on OSes that haven't yet been ported to understand split DNS, by falling back to quad-9 as a global resolver when handed an "impossible to implement" split-DNS config. Part of #953. Needs to be removed before shipping 1.8. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
