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>	2021-06-30 10:11:33 -07:00
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.
