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>	3 years ago

David Anderson	da4cc8bbb4	net/dns: handle all possible translations of high-level DNS config. With this change, all OSes can sort-of do split DNS, except that the default upstream is hardcoded to 8.8.8.8 pending further plumbing. Additionally, Windows 8-10 can do split DNS fully correctly, without the 8.8.8.8 hack. Part of #953. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	e0e677a8f6	net/dns: split out search domains and match domains in OSConfig. It seems that all the setups that support split DNS understand this distinction, and it's an important one when translating high-level configuration. Part of #953. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	a8dcda9c9a	net/dns: start of compat hacks for Windows 7. Correctly reports that Win7 cannot do split DNS, and has a helper to discover the "base" resolvers for the system. Part of #953 Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	3e915ac783	net/dns: implement OS-level split DNS for Windows. Part of #953. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	c16a926bf2	net/dns: set OSConfig.Primary. OS implementations are going to support split DNS soon. Until they're all in place, hardcode Primary=true to get the old behavior. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	de6dc4c510	net/dns: add a Primary field to OSConfig. Currently ignored. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	b2a597b288	net/dns: rename Set to SetDNS in OSConfigurator. wgengine/router.CallbackRouter needs to support both the Router and OSConfigurator interfaces, so the setters can't both be called Set. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	7d84ee6c98	net/dns: unify the OS manager and internal resolver. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
