Brad Fitzpatrick	da8def8e13	all: remove old +build tags The //go:build syntax was introduced in Go 1.17: https://go.dev/doc/go1.17#build-lines gofmt has kept the +build and go:build lines in sync since then, but enough time has passed. Time to remove them. Done with: perl -i -npe 's,^// \+build.*\n,,' $(git grep -l -F '+build') Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago

Aaron Klotz	44f13d32d7	cmd/tailscaled, util/winutil: log Windows service diagnostics when the wintun device fails to install I added new functions to winutil to obtain the state of a service and all its depedencies, serialize them to JSON, and write them to a Logf. When tstun.New returns a wrapped ERROR_DEVICE_NOT_AVAILABLE, we know that wintun installation failed. We then log the service graph rooted at "NetSetupSvc". We are interested in that specific service because network devices will not install if that service is not running.

Brad Fitzpatrick	65c24b6334	envknob: generalize Windows tailscaled-env.txt support ipnserver previously had support for a Windows-only environment variable mechanism that further only worked when Windows was running as a service, not from a console. But we want it to work from tailscaed too, and we want it to work on macOS and Synology. So move it to envknob, now that envknob can change values at runtime post-init. A future change will wire this up for more platforms, and do something more for CLI flags like --port, which the bug was originally about.

Aaron Klotz	d915e0054c	cmd/tailscaled: change Windows service shutdown and add optional event logging Once a stop request is received and the service updates its status to `svc.StopPending`, it should continue running until the shutdown sequence is complete, and then return out of `(*ipnService).Execute`, which automatically sends a `svc.Stopped` notification to Windows. To make this happen, I changed the loop so that it runs until `doneCh` is closed, and then returns. I also removed a spurious `svc.StopPending` notification that the Windows Service Control Manager might be interpreting as a request for more time to shut down. Finally, I added some optional logging that sends a record of service notifications to the Windows event log, allowing us to more easily correlate with any Service Control Manager errors that are sent to the same log.

Brad Fitzpatrick	1db46919ab	cmd/tailscaled: make build fail nicely on older Go versions Due to a bug in Go (golang/go#51778), cmd/go doesn't warn about your Go version being older than the go.mod's declared Go version in that case that package loading fails before the build starts, such as when you use packages that are only in the current version of Go, like our use of net/netip. This change works around that Go bug by adding build tags and a pre-Go1.18-only file that will cause Go 1.17 and earlier to fail like: $ ~/sdk/go1.17/bin/go install ./cmd/tailscaled # tailscale.com/cmd/tailscaled ./required_version.go:11:2: undefined: you_need_Go_1_18_to_compile_Tailscale note: module requires Go 1.18 Change-Id: I39f5820de646703e19dde448dd86a7022252f75c Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago

Aaron Klotz	3a74f2d2d7	cmd/tailscaled, util/winutil: add accessor functions for Windows system policies. This patch adds new functions to be used when accessing system policies, and revises callers to use the new functions. They first attempt the new registry path for policies, and if that fails, attempt to fall back to the legacy path. We keep non-policy variants of these functions because we should be able to retain the ability to read settings from locations that are not exposed to sysadmins for group policy edits. The remaining changes will be done in corp. Updates https://github.com/tailscale/tailscale/issues/3584 Signed-off-by: Aaron Klotz <aaron@tailscale.com>	2 years ago

Brad Fitzpatrick	adc5997592	net/tsdial: give netstack a Dialer, start refactoring name resolution This starts to refactor tsdial.Dialer's name resolution to have different stages: in-memory MagicDNS vs system resolution. A future change will plug in ExitDNS resolution. This also plumbs a Dialer into netstack and unexports the dnsMap internals. And it removes some of the async AddNetworkMapCallback usage and replaces it with synchronous updates of the Dialer's netmap from LocalBackend, since the LocalBackend has the Dialer too.

Brad Fitzpatrick	e6fbc0cd54	cmd/tailscaled, ipn/ipnserver: refactor ipnserver More work towards removing the massive ipnserver.Run and ipnserver.Options and making composable pieces. Work remains. (The getEngine retry loop on Windows complicates things.) For now some duplicate code exists. Once the Windows side is fixed to either not need the retry loop or to move the retry loop into a custom wgengine.Engine wrapper, then we can unify tailscaled_windows.go too.

Aaron Klotz	df7899759d	cmd/tailscaled: set the correct flag for receiving Windows session change events This feature wasn't working until I realized that we also need to opt into the events.

Aaron Klotz	e016eaf410	cmd/tailscaled: conditionally flush Windows DNS cache on SessionChange For the service, all we need to do is handle the `svc.SessionChange` command. Upon receipt of a `windows.WTS_SESSION_UNLOCK` event, we fire off a goroutine to flush the DNS cache. (Windows expects responses to service requests to be quick, so we don't want to do that synchronously.) This is gated on an integral registry value named `FlushDNSOnSessionUnlock`, whose value we obtain during service initialization. (See [this link](https://docs.microsoft.com/en-us/windows/win32/api/winsvc/nc-winsvc-lphandler_function_ex) for information re: handling `SERVICE_CONTROL_SESSIONCHANGE`.)

Brad Fitzpatrick	ed8587f90d	wgengine/router: take a link monitor Prep for #1591 which will need to make Linux's router react to changes that the link monitor observes.

Brad Fitzpatrick	7f7a81e5ae	cmd/tailscaled: add func to create ipnserver.Opts To unify the Windows service and non-service/non-Windows paths a bit. And provides a way to make Linux act like Windows for testing. (notably, for testing the fix to #2137) One perhaps visible change of this is that tailscaled.exe when run in cmd.exe/powershell (not as a Windows Service) no longer uses the "_daemon" autostart key. But in addition to being naturally what falls out of this change, that's also what Windows users would likely want, as otherwise the unattended mode user is ignored when the "_daemon" autostart key is specified. Notably, this would let people debug what their normally-run-as-a-service tailscaled is doing, even when they're running in Unattended Mode.

Brad Fitzpatrick	91c9c33036	cmd/tailscaled: don't block ipnserver startup behind engine init on Windows With this change, the ipnserver's safesocket.Listen (the localhost tcp.Listen) happens right away, before any synchronous TUN/DNS/Engine/etc setup work, which might be slow, especially on early boot on Windows. Because the safesocket.Listen starts up early, that means localhost TCP dials (the safesocket.Connect from the GUI) complete successfully and thus the GUI avoids the MessageBox error. (I verified that pacifies it, even without a Listener.Accept; I'd feared that Windows localhost was maybe special and avoided the normal listener backlog). Once the GUI can then connect immediately without errors, the various timeouts then matter less, because the backend is no longer trying to race against the GUI's timeout. So keep retrying on errors for a minute, or 10 minutes if the system just booted in the past 10 minutes. This should fix the problem with Windows 10 desktops auto-logging in and starting the Tailscale frontend which was then showing a MessageBox error about failing to connect to tailscaled, which was slow coming up because the Windows networking stack wasn't up yet.
