Brad Fitzpatrick	f6e3240dee	cmd/tailscale/cli: add test to catch ipn.Pref additions	3 years ago
Avery Pennarun	6caa02428e	cmd/tailscale/cli/up: "LoggedOut" pref is implicit. ... There's no need to warn that it was not provided on the command line after doing a sequence of up; logout; up --args. If you're asking for tailscale to be up, you always mean that you prefer LoggedOut to become false. Fixes #1828 Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	3 years ago
Avery Pennarun	19c3e6cc9e	types/logger: rate limited: more hysteresis, better messages. ... - Switch to our own simpler token bucket, since x/time/rate is missing necessary stuff (can't provide your own time func; can't check the current bucket contents) and it's overkill anyway. - Add tests that actually include advancing time. - Don't remove the rate limit on a message until there's enough room to print at least two more of them. When we do, we'll also print how many we dropped, as a contextual reminder that some were previously lost. (This is more like how the Linux kernel does it.) - Reformat the [RATE LIMITED] messages to be shorter, and to not corrupt original message. Instead, we print the message, then print its format string. - Use %q instead of \"%s\", for more accurate parsing later, if the format string contained quotes.

Josh Bleecher Snyder	3c543c103a	wgengine/magicsock: unify initial bind and rebind ... We had two separate code paths for the initial UDP listener bind and any subsequent rebinds. IPv6 got left out of the rebind code. Rather than duplicate it there, unify the two code paths. Then improve the resulting code: * Rebind had nested listen attempts to try the user-specified port first, and then fall back to :0 if that failed. Convert that into a loop. * Initial bind tried only the user-specified port. Rebind tried the user-specified port and 0. But there are actually three ports of interest: The one the user specified, the most recent port in use, and 0. We now try all three in order, as appropriate. * In the extremely rare case in which binding to port 0 fails, use a dummy net.PacketConn whose reads block until close. This will keep the wireguard-go receive func goroutine alive. As a pleasant side-effect of this, if we decide that we need to resuscitate #1796, it will now be much easier.

David Anderson	25ce9885a2	net/dns: don't use NM+resolved for NM >=1.26.6. ... NetworkManager fixed the bug that forced us to use NetworkManager if it's programming systemd-resolved, and in the same release also made NetworkManager ignore DNS settings provided for unmanaged interfaces... Which breaks what we used to do. So, with versions 1.26.6 and above, we MUST NOT use NetworkManager to indirectly program systemd-resolved, but thankfully we can talk to resolved directly and get the right outcome.

Brad Fitzpatrick	e40e5429c2	cmd/tailscale/cli: make 'tailscale up' protect --advertise-exit-node removal ... The new "tailscale up" checks previously didn't protect against --advertise-exit-node being omitted in the case that --advertise-routes was also provided. It wasn't done before because there is no corresponding pref for "--advertise-exit-node"; it's a helper flag that augments --advertise-routes. But that's an implementation detail and we can still help users. We just have to special case that pref and look whether the current routes include both the v4 and v6 /0 routes.

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. Fingers crossed. Fixes #1313 (previously #1187, etc) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Alex Brainman	7689213aaa	cmd/tailscaled: add subcommands to install and remove tailscaled Windows service ...

Brad Fitzpatrick	f99e63bb17	ipn: don't Logout when Windows GUI disconnects ... Logout used to be a no-op, so the ipnserver previously synthensized a Logout on disconnect. Now that Logout actually invalidates the node key that was forcing all GUI closes to log people out. Instead, add a method to LocalBackend to specifically mean "the Windows GUI closed, please forget all the state".

Brad Fitzpatrick	f42ded7acf	cmd/tailscale/cli: relax & improve the running-as-CLI check for macOS ... On macOS, we link the CLI into the GUI executable so it can be included in the Mac App Store build. You then need to run it like: /Applications/Tailscale.app/Contents/MacOS/Tailscale <command> But our old detection of whether you're running that Tailscale binary in CLI mode wasn't accurate and often bit people. For instance, when they made a typo, it then launched in GUI mode and broke their existing GUI connection (starting a new IPNExtension) and took down their network.

Brad Fitzpatrick	49808ae6ea	ipn{,/ipnlocal}, cmd/tailscale/cli: don't check pref reverts on initial up ... The ipn.NewPrefs func returns a populated ipn.Prefs for historical reasons. It's not used or as important as it once was, but it hasn't yet been removed. Meanwhile, it contains some default values that are used on some platforms. Notably, for this bug (#1725), Windows/Mac use its Prefs.RouteAll true value (to accept subnets), but Linux users have always gotten a "false" value for that, because that's what cmd/tailscale's CLI default flag is _for all operating systems_. That meant that "tailscale up" was rightfully reporting that the user was changing an implicit setting: RouteAll was changing from true with false with the user explicitly saying so. An obvious fix might be to change ipn.NewPrefs to return Prefs.RouteAll == false on some platforms, but the logic is complicated by darwin: we want RouteAll true on windows, android, ios, and the GUI mac app, but not the CLI tailscaled-on-macOS mode. But even if we used build tags (e.g. the "redo" build tag) to determine what the default is, that then means we have duplicated and differing "defaults" between both the CLI up flags and ipn.NewPrefs. Furthering that complication didn't seem like a good idea. So, changing the NewPrefs defaults is too invasive at this stage of the release, as is removing the NewPrefs func entirely. Instead, tweak slightly the semantics of the ipn.Prefs.ControlURL field. This now defines that a ControlURL of the empty string means both "we're uninitialized" and also "just use the default". Then, once we have the "empty-string-means-unintialized" semantics, use that to suppress "tailscale up"'s recent implicit-setting-revert checking safety net, if we've never initialized Tailscale yet. And update/add tests. Fixes #1725 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago

Previously "tailscale up" always did a new Start and reset all the settings. Now "tailscale up" with no flags just brings the world [back] up. (The opposite of "tailscale down"). But with flags, "tailscale up" now only is allowed to change preferences if they're explicitly named in the flags. Otherwise it's an error. Or you need to use --reset to explicitly nuke everything.
