Brad Fitzpatrick	7c1ed38ab3	ipn/ipnlocal: fix missing controlknobs.Knobs plumbing ... I missed connecting some controlknobs.Knobs pieces in 4e91cf20a8 resulting in that breaking control knobs entirely. Whoops. The fix in ipn/ipnlocal (where it makes a new controlclient) but to atone, I also added integration tests. Those integration tests use a new "tailscale debug control-knobs" which by itself might be useful for future debugging.

Brad Fitzpatrick	055fdb235f	cmd/tailscaled, tstest/integration: make tailscaled die when parent dies ... I noticed that failed tests were leaving aroudn stray tailscaled processes on macOS at least. To repro, add this to tstest/integration: func TestFailInFewSeconds(t *testing.T) { t.Parallel() time.Sleep(3 * time.Second) os.Exit(1) t.Fatal("boom") } Those three seconds let the other parallel tests (with all their tailscaled child processes) start up and start running their tests, but then we violently os.Exit(1) the test driver and all the children were kept alive (and were spinning away, using all available CPU in gvisor scheduler code, which is a separate scary issue) Updates #cleanup Change-Id: I9c891ed1a1ec639fb2afec2808c04dbb8a460e0e Co-authored-by: Maisem Ali <maisem@tailscale.com> Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	1 year ago

We're using it in more and more places, and it's not really specific to our use of Wireguard (and does more just link/interface monitoring).

Anton Tolchanov	8546ff98fb	tsweb: move varz handler(s) into separate modules ... This splits Prometheus metric handlers exposed by tsweb into two modules: - `varz.Handler` exposes Prometheus metrics generated by our expvar converter; - `promvarz.Handler` combines our expvar-converted metrics and native Prometheus metrics. By default, tsweb will use the promvarz handler, however users can keep using only the expvar converter. Specifically, `tailscaled` now uses `varz.Handler` explicitly, which avoids a dependency on the (heavyweight) Prometheus client.

Aaron Klotz	98f21354c6	cmd/tailscaled: add a special command to tailscaled's Windows service for removing WinTun ... WinTun is installed lazily by tailscaled while it is running as LocalSystem. Based upon what we're seeing in bug reports and support requests, removing WinTun as a lesser user may fail under certain Windows versions, even when that user is an Administrator. By adding a user-defined command code to tailscaled, we can ask the service to do the removal on our behalf while it is still running as LocalSystem. * The uninstall code is basically the same as it is in corp; * The command code will be sent as a service control request and is protected by the SERVICE_USER_DEFINED_CONTROL access right, which requires Administrator. I'll be adding follow-up patches in corp to engage this functionality. Updates https://github.com/tailscale/tailscale/issues/6433 Signed-off-by: Aaron Klotz <aaron@tailscale.com>	2 years ago

Brad Fitzpatrick	3b0de97e07	cmd/tailscaled: unify the two Windows paths + separate IPN server path ... tailscaled on Windows had two entirely separate start-up paths for running as a service vs in the foreground. It's been causing problems for ages. This unifies the two paths, making them be the same as the path used for every other platform. Also, it uses the new async LocalBackend support in ipnserver.Server so the Server can start serving HTTP immediately, even if tun takes awhile to come up. Updates #6535 Change-Id: Icc8c4f96d4887b54a024d7ac15ad11096b5a58cf Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Brad Fitzpatrick	e8cc78b1af	ipn/ipnserver: change Server to let LocalBackend be supplied async ... This is step 1 of de-special-casing of Windows and letting the LocalAPI HTTP server start serving immediately, even while the rest of the world (notably the Engine and its TUN device) are being created, which can take a few to dozens of seconds on Windows. With this change, the ipnserver.New function changes to not take an Engine and to return immediately, not returning an error, and let its Run run immediately. If its ServeHTTP is called when it doesn't yet have a LocalBackend, it returns an error. A TODO in there shows where a future handler will serve status before an engine is available. Future changes will: * delete a bunch of tailscaled_windows.go code and use this new API * add the ipnserver.Server ServerHTTP handler to await the engine being available * use that handler in the Windows GUI client Updates #6522 Change-Id: Iae94e68c235e850b112a72ea24ad0e0959b568ee Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Aaron Klotz	033bd94d4c	cmd/tailscaled, wgengine/router: use wingoes/com for COM initialization instead of go-ole ... This patch removes the crappy, half-backed COM initialization used by `go-ole` and replaces that with the `StartRuntime` function from `wingoes`, a library I have started which, among other things, initializes COM properly. In particular, we should always be initializing COM to use the multithreaded apartment. Every single OS thread in the process becomes implicitly initialized as part of the MTA, so we do not need to concern ourselves as to whether or not any particular OS thread has initialized COM. Furthermore, we no longer need to lock the OS thread when calling methods on COM interfaces. Single-threaded apartments are designed solely for working with Win32 threads that have a message pump; any other use of the STA is invalid.

The hujson package transition to just being a pure AST parser and formatter for HuJSON and not an unmarshaler. Thus, parse HuJSON as such, convert it to JSON, and then use the standard JSON unmarshaler. Signed-off-by: Joe Tsai <joetsai@digital-static.net>	3 years ago

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	8ee044ea4a	ssh/tailssh: make the SSH server a singleton, register with LocalBackend ... Remove the weird netstack -> tailssh dependency and instead have tailssh register itself with ipnlocal when linked. This makes tailssh.server a singleton, so we can have a global map of all sessions.

Brad Fitzpatrick	d5f8f38ac6	tailcfg: rename map request version to "capability version" ... And add a CapabilityVersion type, primarily for documentation. This makes MapRequest.Version, RegisterRequest.Version, and SetDNSRequest.Version all use the same version, which will avoid confusing in the future if Register or SetDNS ever changed their semantics on Version change. (Currently they're both always 1) This will requre a control server change to allow a SetDNSRequest.Version value other than 1 to be deployed first.
