Jordan Whited	76389d8baf	net/tstun, wgengine/magicsock: enable vectorized I/O on Linux (#6663 ) This commit updates the wireguard-go dependency and implements the necessary changes to the tun.Device and conn.Bind implementations to support passing vectors of packets in tailscaled. This significantly improves throughput performance on Linux.

shayne	98114bf608	cmd/tailscale/cli, ipn/localapi: add funnel status to status command (#6402 ) Fixes #6400 open up GETs for localapi serve-config to allow read-only access to ServeConfig `tailscale status` will include "Funnel on" status when Funnel is configured. Prints nothing if Funnel is not running. Example: $ tailscale status <nodes redacted> # Funnel on: # - https://node-name.corp.ts.net # - https://node-name.corp.ts.net:8443 # - tcp://node-name.corp.ts.net:10000 Signed-off-by: Shayne Sweeney <shayne@tailscale.com>	2 years ago
David Anderson	1b65630e83	cmd/containerboot: switch to IPN bus monitoring instead of polling. We still have to shell out to `tailscale up` because the container image's API includes "arbitrary flags to tailscale up", unfortunately. But this should still speed up startup a little, and also enables k8s-bound containers to update their device information as new netmap updates come in.

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

Maisem Ali	96cad35870	cmd/tailscaled: rename variables to be more descriptive renamed from `useNetstack` to `onlyNetstack` which is 1 letter more but more descriptive because we always have netstack enabled and `useNetstack` doesn't convey what it is supposed to be used for. e.g. we always use netstack for Tailscale SSH.

Denton Gentry	a200a23f97	Revert "cmd/tailscale: access QNAP via localhost" When running `tailscale web` as a standalone process, it was necessary to send auth requests to QTS using localhost to avoid hitting the proxy recursively. However running `tailscale web` as a process means it is consuming RAM all the time even when it isn't actively doing anything. After switching back to the `tailscale web` CGI mode, we don't need to specifically use localhost for QNAP auth. This reverts commit `e0cadc5496`.

Brad Fitzpatrick	0a10a5632b	cmd/tailscaled: add TS_DEBUG_BACKEND_DELAY_SEC for testing async startup This adds an envknob to make testing async startup more reproducible. We want the Windows GUI to behave well when wintun is not (or it's doing its initial slow driver installation), but during testing it's often too fast to see that it's working.

Joe Tsai	2e5d08ec4f	net/connstats: invert network logging data flow (#6272 ) Previously, tstun.Wrapper and magicsock.Conn managed their own statistics data structure and relied on an external call to Extract to extract (and reset) the statistics. This makes it difficult to ensure a maximum size on the statistics as the caller has no introspection into whether the number of unique connections is getting too large. Invert the control flow such that a connstats.Statistics is registered with tstun.Wrapper and magicsock.Conn. Methods on non-nil connstats.Statistics are called for every packet. This allows the implementation of connstats.Statistics (in the future) to better control when it needs to flush to ensure bounds on maximum sizes. The value registered into tstun.Wrapper and magicsock.Conn could be an interface, but that has two performance detriments: 1. Method calls on interface values are more expensive since they must go through a virtual method dispatch. 2. The implementation would need a sync.Mutex to protect the statistics value instead of using an atomic.Pointer. Given that methods on constats.Statistics are called for every packet, we want reduce the CPU cost on this hot path. Signed-off-by: Joe Tsai <joetsai@digital-static.net>	2 years ago
Joe Tsai	35c10373b5	types/logid: move logtail ID types here (#6336 ) Many packages reference the logtail ID types, but unfortunately pull in the transitive dependencies of logtail.

Aaron Klotz	6e33d2da2b	ipn/ipnauth, util/winutil: add temporary LookupPseudoUser workaround to address os/user.LookupId errors on Windows I added util/winutil/LookupPseudoUser, which essentially consists of the bits that I am in the process of adding to Go's standard library.

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.

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.
