Adrian Dewhurst	04dd6d1dae	control/controlclient: sign RegisterRequest (#1549 ) control/controlclient: sign RegisterRequest Some customers wish to verify eligibility for devices to join their tailnets using machine identity certificates. TLS client certs could potentially fulfill this role but the initial customer for this feature has technical requirements that prevent their use. Instead, the certificate is loaded from the Windows local machine certificate store and uses its RSA public key to sign the RegisterRequest message. There is room to improve the flexibility of this feature in future and it is currently only tested on Windows (although Darwin theoretically works too), but this offers a reasonable starting place for now.

Brad Fitzpatrick	e3df29d488	wgengine{,/monitor}: move interface state fetching/comparing to monitor Gets it out of wgengine so the Engine isn't responsible for being a callback registration hub for it.

Frederik “Freso” S. Olesen	83fccf9fe5	tailscaled.service: Lock down clock and /dev (#1071 ) Research in issue #1063 uncovered why tailscaled would fail with ProtectClock enabled (it implicitly enabled DevicePolicy=closed). This knowledge in turn also opens the door for locking down /dev further, e.g. explicitly setting DevicePolicy=strict (instead of closed), and making /dev private for the unit. Additional possible future (or downstream) lockdown that can be done is setting `PrivateDevices=true` (with `BindPaths=/dev/net/`), however, systemd 233 or later is required for this, and tailscaled currently need to work for systemd down to version 215.

Brad Fitzpatrick	515866d7c6	ipn, ipnserver, cmd/tailscale: add "server mode" support on Windows This partially (but not yet fully) migrates Windows to tailscaled's StateStore storage system. This adds a new bool Pref, ForceDaemon, defined as: // ForceDaemon specifies whether a platform that normally // operates in "client mode" (that is, requires an active user // logged in with the GUI app running) should keep running after the // GUI ends and/or the user logs out. // // The only current applicable platform is Windows. This // forced Windows to go into "server mode" where Tailscale is // running even with no users logged in. This might also be // used for macOS in the future. This setting has no effect // for Linux/etc, which always operate in daemon mode. Then, when ForceDaemon becomes true, we now write use the StateStore to track which user started it in server mode, and store their prefs under that key. The ipnserver validates the connections/identities and informs that LocalBackend which userid is currently in charge. The GUI can then enable/disable server mode at runtime, without using the CLI. But the "tailscale up" CLI was also fixed, so Windows users can use authkeys or ACL tags, etc. Updates #275	5 years ago

And make the DERP map support multiple nodes per region with clients picking the first one that's available. (The server will balance the order presented to clients for load balancing) This deletes the stunner package, merging it into the netcheck package instead, to minimize all the config hooks that would've been required.

Avery Pennarun	af9328c1b7	log rate limiting: reformat limiter messages, and use nonempty burst size. - Reformat the warning about a message being rate limited to print the format string, rather than the formatted message. This helps give a clue what "type" of message is being limited. - Change the rate limit warning to be [RATE LIMITED] in all caps. This uses less space on each line, plus is more noticeable. - In tailscaled, change the frequency to be less often (once every 5 seconds per format string) but to allow bursts of up to 5 messages. This greatly reduces the number of messages that are rate limited during startup, but allows us to tighten the limit even further during normal runtime.

As a result, we had also left it out of macOS, and so we didn't print netmap diffs at all on darwin-based platforms. Oops. As a bonus, the output format of the new function is way better. Minor oddity: because I used the dumbest possible diff algorithm, the sort order is a bit dumb. We print all "removed" lines and then print all "added" lines, rather than doing the usual diff-like thing of interspersing them. This probably doesn't matter (maybe it's an improvement).	6 years ago

David Anderson	4460bd638b	safesocket: simplify API. On unix, we want to provide a full path to the desired unix socket. On windows, currently we want to provide a TCP port, but someday we'll also provide a "path-ish" object for a named pipe. For now, simplify the API down to exactly a path and a TCP port.

Brad Fitzpatrick	b72e6446e2	cmd/derper: add a basic DERP server Mostly Crawshaw's earlier code, refactored a bit. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	6 years ago
David Anderson	47da432991	ipn: handle advertised routes provided by frontend. Signed-off-by: David Anderson <dave@natulte.net>	6 years ago
David Anderson	62fb652eef	cmd/tailscaled: run off internal state autonomously. With this change, tailscaled can be restarted and reconnect without interaction from `tailscale`, and `tailscale` is merely there to provide login assistance and adjust preferences.

Brad Fitzpatrick	79295b1138	wgengine: simplify, change some signatures * make RouterGen return an error, not take both tunname and tundev * also remove RouteGen taking a wireguard/device.Device; currently unused * remove derp parameter (it'll work differently) * unexport NewUserspaceRouter in per-OS impls, add documented wrapper Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	6 years ago
David Anderson	dec5d64593	ipn/ipnserver: remove Options.AllowQuit. It was previously used by the MacOS client, but it now does something different. ipnserver should never obey a client's request to exit. Signed-off-by: David Anderson <dave@natulte.net>	6 years ago

David Anderson	5bc632271b	Introduce a state store to LocalBackend. The store is passed-in by callers of NewLocalBackend and ipnserver.Run, but currently all callers are hardcoded to an in-memory store. The store is unused. Signed-Off-By: David Anderson <dave@natulte.net>	6 years ago
David Anderson	21280ca2d1	Make ipn.Options.Prefs a pointer. This is a prelude to making it truly optional, once state management has moved into the backend. For now though, it's still required. This change is just isolating the bubbling-up of the pointerification into other layers. Signed-Off-By: David Anderson <dave@natulte.net>	6 years ago
David Anderson	f6f154193f	Remove LoginFlags from Backend options. - It was only used in one currently-unused client. - It's an imperative command, not a configuration setting. - The LoginFlags stuff in controlclient feels like it needs a refactor anyway. I'll put this logic back once ipnd owns its state and Backend commands reflect that. Signed-Off-By: David Anderson <dave@natulte.net>	6 years ago

Martin Baillie	3d5ef74f26	tailscaled: add tunnel name and port flags OpenBSD tunnel names are prefixed with `tun`. Controlling the port allows for deterministic configuration of firewall rules (using `pf` in this case). Signed-off-by: Martin Baillie <martin@baillie.email>	6 years ago

David Anderson	ea11d58e96	debian: fix changelog generation. It seems changelog generation got broken by moving the code between corp and OSS repos, because one of the commit SHAs doesn't have an associated tag. In the interest of fixing the build, and because we're not yet trying to upstream the debian package, I fixed this by allowing hash-based versions to show up in the changelog. This maybe wrong from a debian standards perspective, but for our current point in life it'll work until we learn to do it better. Signed-Off-By: David Anderson <dave@natulte.net>	6 years ago
