David Anderson	87eb8384f5	net/dns: fix up NetworkManager configurator a bit. Clear LLMNR and mdns flags, update reasoning for our settings, and set our override priority harder than before when we want to be primary resolver. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago

David Anderson	143e5dd087	net/dns: rename script variable. Debian resolvconf is not legacy, it's alive and well, just historically before the other implementations. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago

David Anderson	e638a4d86b	net/dns: make directManager support split DNS, and work in sandboxes. Fixes #1495, #683. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
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	b9e194c14b	net/dns: add missing FQDN qualification. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago

David Anderson	4a64d2a603	net/dns: some post-review cleanups. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	720c1ad0f0	net/dns: insert OS base config when emulating split DNS. Part of #953. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	e560be6443	net/dns: sort matchDomains to avoid test flake. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	68f76e9aa1	net/dns: add GetBaseConfig to OSConfigurator interface. Part of #953, required to make split DNS work on more basic platforms. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	fe9cd61d71	net/dns: add tests for DNS config generation. Part of #953. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	0ba6d03768	net/dns/resolver: add a test helper to get at the resolver config. 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
Brad Fitzpatrick	939861773d	net/tstun: accept peerapi connections through the filter Fixes tailscale/corp#1545 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Maisem Ali	57756ef673	net/nettest: make nettest.NewConn pass x/net/nettest.TestConn. Signed-off-by: Maisem Ali <maisem@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	bc4381447f	net/tstun: return the real interface name at device creation. This is usually the same as the requested interface, but on some unixes can vary based on device number allocation, and on Windows it's the GUID instead of the pretty name, since everything relating to configuration wants the GUID. 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

David Anderson	748670f1e9	net/dns: fix typo in docstring. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	a39d2403bc	net/dns: disable NetworkManager and resolved configurators temporarily. They need some rework to do the right thing, in the meantime the direct and resolvconf managers will work out. The resolved implementation was never selected due to control-side settings. The networkmanager implementation mostly doesn't get selected due to unforeseen interactions with `resolvconf` on many platforms. Both implementations also need rework to support the various routing modes they're capable of. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	befd8e4e68	net/dns: replace managerImpl with OSConfigurator in code. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	077d4dc8c7	net/dns: add an OSConfigurator interface. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	6ad44f9fdf	wgengine: take in dns.Config, split out to resolver.Config and dns.OSConfig. Stepping stone towards having the DNS package handle the config splitting. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	2edb57dbf1	net/dns: add new Config that captures tailscale+OS DNS config. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	8af9d770cf	net/dns: rename Config to OSConfig. Making way for a new higher level config struct. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	fcfc0d3a08	net/dns: remove ManagerConfig, pass relevant args directly. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
