Brad Fitzpatrick	41fd4eab5c	envknob: add new package for all the strconv.ParseBool(os.Getenv(..)) A new package can also later record/report which knobs are checked and set. It also makes the code cleaner & easier to grep for env knobs. Change-Id: Id8a123ab7539f1fadbd27e0cbeac79c2e4f09751 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	8df3fa4638	net/dns: make WSL network configuration opt-in for now Tailscale seems to be breaking WSL configurations lately. Until we understand what changed, turn off Tailscale's involvement by default and make it opt-in.

David Crawshaw	6b9f8208f4	net/dns: do not run wsl.exe as LocalSystem It doesn't work. It needs to run as the user. https://github.com/microsoft/WSL/issues/4803 The mechanism for doing this was extracted from: https://web.archive.org/web/20101009012531/http://blogs.msdn.com/b/winsdk/archive/2009/07/14/launching-an-interactive-process-from-windows-service-in-windows-vista-and-later.aspx While here, we also reclaculate WSL distro set on SetDNS. This accounts for: 1. potential inability to access wsl.exe on startup 2. WSL being installed while Tailscale is running 3. A new WSL distrobution being installed Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	3 years ago
David Crawshaw	1147c7fd4f	net/dns: set WSL /etc/resolv.conf We also have to make a one-off change to /etc/wsl.conf to stop every invocation of wsl.exe clobbering the /etc/resolv.conf. This appears to be a safe change to make permanently, as even though the resolv.conf is constantly clobbered, it is always the same stable internal IP that is set as a nameserver. (I believe the resolv.conf clobbering predates the MS stub resolver.) Tested on WSL2, should work for WSL1 too. Fixes #775 Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	3 years ago
David Anderson	084d48d22d	net/dns: always proxy through quad-100 on windows 8.1. Windows 8.1 incorrectly handles search paths on an interface with no associated resolver, so we have to provide a full primary DNS config rather than use Windows 8.1's nascent-but-present NRPT functionality. Fixes #2237. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	44c2b7dc79	net/dns: on windows, skip site-local v6 resolvers. Further refinement for tailscale/corp#1662. Signed-off-by: David Anderson <danderson@tailscale.com>	4 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>	4 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.

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>	4 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>	4 years ago
