Brad Fitzpatrick	36b1df1241	cmd/tailscale/cli: add --watch flag to "debug metrics" subcommand ... This adds a new --watch flag that prints out a block of metric changes every second, if anything changed.

Brad Fitzpatrick	945290cc3f	cmd/tailscale/cli: migrate hidden debug subcommand to use subcomands ... It was a mess of flags. Use subcommands under "debug" instead.

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.

Josh Bleecher Snyder	3fd5f4380f	util/multierr: new package ... github.com/go-multierror/multierror served us well.

Brad Fitzpatrick	3618e8d8ac	cmd/tailscaled: rename outbound HTTP proxy flag ... The old name invited confusion: * is this the HTTP proxy to use ourselves? (no, that's via an environment variable, per proxy conventions) * is this for LetsEncrypt https-to-localhost-http proxying? (no, that'll come later) So rename to super verbose --outbound-http-proxy-listen before the 1.16.0 release to make it clear what it is. It listens (serves) and it's for outbound, not inbound.

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	a7cb241db1	cmd/tailscaled: add support for running an HTTP proxy ... This adds support for tailscaled to be an HTTP proxy server.

Brad Fitzpatrick	ace2faf7ec	cmd/tailscale: make debug profiling output - mean stdout ... Because the macOS CLI runs in the sandbox, including the filesystem, so users would be confused that -cpu-profile=prof.cpu succeeds but doesn't write to their current directory, but rather in some random Library/Containers directory somewhere on the machine (which varies depending on the Mac build type: App Store vs System Extension) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	efb84ca60d	ipn/localapi, cmd/tailscale: add CPU & memory profile support, debug command ... This was already possible on Linux if you ran tailscaled with --debug (which runs net/http/pprof), but it requires the user have the Go toolchain around. Also, it wasn't possible on macOS, as there's no way to run the IPNExtension with a debug server (it doesn't run tailscaled). And on Windows it's super tedious: beyond what users want to do or what we want to explain. Instead, put it in "tailscale debug" so it works and works the same on all platforms. Then we can ask users to run it when we're debugging something and they can email us the output files. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago

Aaron Klotz	9ebb5d4205	ipn, paths: ensure that the state directory for Windows has the correct perms ... ProgramData has a permissive ACL. For us to safely store machine-wide state information, we must set a more restrictive ACL on our state directory. We set the ACL so that only talescaled's user (ie, LocalSystem) and the Administrators group may access our directory. We must include Administrators to ensure that logs continue to be easily accessible; omitting that group would force users to use special tools to log in interactively as LocalSystem, which is not ideal. (Note that the ACL we apply matches the ACL that was used for LocalSystem's AppData\Local). There are two cases where we need to reset perms: One is during migration from the old location to the new. The second case is for clean installations where we are creating the file store for the first time. Updates #2856 Signed-off-by: Aaron Klotz <aaron@tailscale.com>	3 years ago
