Avery Pennarun	4f3315f3da	ipnlocal: setting WantRunning with EditPrefs was special. ... EditPrefs should be just a wrapper around the action of changing prefs, but someone had added a side effect of calling Login() sometimes. The side effect happened *after* running the state machine, which would sometimes result in us going into NeedsLogin immediately before calling cc.Login(). This manifested as the macOS app not being able to Connect if you launched it with LoggedOut=false and WantRunning=false. Trying to Connect() would sent us to the NeedsLogin state instead.

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.

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	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.

Brad Fitzpatrick	53cfff109b	ipn: replace SetWantRunning(bool) with EditPrefs(MaskedPrefs) ... This adds a new ipn.MaskedPrefs embedding a ipn.Prefs, along with a bunch of "has bits", kept in sync with tests & reflect. Then it adds a Prefs.ApplyEdits(MaskedPrefs) method. Then the ipn.Backend interface loses its weirdo SetWantRunning(bool) method (that I added in 483141094c for "tailscale down") and replaces it with EditPrefs (alongside the existing SetPrefs for now). Then updates 'tailscale down' to use EditPrefs instead of SetWantRunning. In the future, we can use this to do more interesting things with the CLI, reconfiguring only certain properties without the reset-the-world "tailscale up".
