Brad Fitzpatrick	2f17a34242	ipn/ipnlocal: fix tailscale status --json AuthURL field It was getting cleared on notify. Document that authURL is cleared on notify and add a new field that isn't, using the new field for the JSON status. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago

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>	4 years ago
David Anderson	6fd9e28bd0	ipn/ipnlocal: add arpa suffixes to MagicDNS for reverse lookups. This used to not be necessary, because MagicDNS always did full proxying. But with split DNS, we need to know which names to route to our resolver, otherwise reverse lookups break. This captures the entire CGNAT range, as well as our Tailscale ULA.

David Anderson	48d4f14652	ipn/ipnlocal: only set authoritative domains when using MagicDNS. Otherwise, the existence of authoritative domains forces full DNS proxying even when no other DNS config is present. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
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	8570f82c8b	ipn/ipnlocal: finish/fix up filename validation & encoding on disk It used to just store received files URL-escaped on disk, but that was a half done lazy implementation, and pushed the burden to callers to validate and write things to disk in an unescaped way. Instead, do all the validation in the receive handler and only accept filenames that are UTF-8 and in the intersection of valid names that all platforms support.

Brad Fitzpatrick	8f3e453356	ipn, cmd/tailscale/cli: add pref to configure sudo-free operator user From discussion with @danderson. Fixes #1684 (in a different way) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
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>	4 years ago

Brad Fitzpatrick	34d2f5a3d9	tailcfg: add Endpoint, EndpointType, MapRequest.EndpointType Track endpoints internally with a new tailcfg.Endpoint type that includes a typed netaddr.IPPort (instead of just a string) and includes a type for how that endpoint was discovered (STUN, local, etc). Use []tailcfg.Endpoint instead of []string internally. At the last second, send it to the control server as the existing []string for endpoints, but also include a new parallel MapRequest.EndpointType []tailcfg.EndpointType, so the control server can start filtering out less-important endpoint changes from new-enough clients. Notably, STUN-discovered endpoints can be filtered out from 1.6+ clients, as they can discover them amongst each other via CallMeMaybe disco exchanges started over DERP. And STUN endpoints change a lot, causing a lot of MapResposne updates. But portmapped endpoints are worth keeping for now, as they they work right away without requiring the firewall traversal extra RTT dance. End result will be less control->client bandwidth. (despite negligible increase in client->control bandwidth) Updates tailscale/corp#1543 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago

Brad Fitzpatrick	9972c02b60	cmd/tailscale/cli: don't let up change prefs based on implicit flag values This changes the behavior of "tailscale up". 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.
