Maisem Ali	dd50dcd067	ipn/ipnlocal: handle untagging nodes better We would end up with duplicate profiles for the node as the UserID would have chnaged. In order to correctly deduplicate profiles, we need to look at both the UserID and the NodeID. A single machine can only ever have 1 profile per NodeID and 1 profile per UserID. Note: UserID of a Node can change when the node is tagged/untagged, and the NodeID of a device can change when the node is deleted so we need to check for both.

Maisem Ali	235309adc4	all: store NL keys per profile This moves the NetworkLock key from a dedicated StateKey to be part of the persist.Persist struct. This struct is stored as part for ipn.Prefs and is also the place where we store the NodeKey. It also moves the ChonkDir from "/tka" to "/tka-profile/<profile-id>". The rename was intentional to be able to delete the "/tka" dir if it exists. This means that we will have a unique key per profile, and a unique directory per profile. Note: `tailscale logout` will delete the entire profile, including any keys. It currently does not delete the ChonkDir. Signed-off-by: Maisem Ali <maisem@tailscale.com>	3 years ago
Maisem Ali	fe81ee62d7	ipn/ipnlocal: do controlclient.Shutdown in a different goroutine We do not need to wait for it to complete.

Brad Fitzpatrick	3f8e185003	health: add Warnable, move ownership of warnable items to callers The health package was turning into a rando dumping ground. Make a new Warnable type instead that callers can request an instance of, and then Set it locally in their code without the health package being aware of all the things that are warnable. (For plenty of things the health package will want to know details of how Tailscale works so it can better prioritize/suppress errors, but lots of the warnings are pretty leaf-y and unrelated) This just moves two of the health warnings. Can probably move more later. Change-Id: I51e50e46eb633f4e96ced503d3b18a1891de1452 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago

Aaron Klotz	73b8968404	ipn/ipnlocal: ensure Persist information is saved to server mode start state Numerous issues have been filed concerning an inability to install and run Tailscale headlessly in unattended mode, particularly after rebooting. The server mode `Prefs` stored in `server-state.conf` were not being updated with `Persist` state once the node had been succesfully logged in. Users have been working around this by finagling with the GUI to make it force a state rewrite. This patch makes that unnecessary by ensuring the required server mode state is updated when prefs are updated by the control client.

Tom DNetto	a515fc517b	ipn/ipnlocal: make tkaSyncIfNeeded exclusive with a mutex Running corp/ipn#TestNetworkLockE2E has a 1/300 chance of failing, and deskchecking suggests thats whats happening are two netmaps are racing each other to be processed through tkaSyncIfNeededLocked. This happens in the first place because we release b.mu during network RPCs. To fix this, we make the tka sync logic an exclusive section, so two netmaps will need to wait for tka sync to complete serially (which is what we would want anyway, as the second run through probably wont need to sync).

Brad Fitzpatrick	88c2afd1e3	ipn/ipnlocal, net/dns, util/cloudenv: specialize DNS config on Google Cloud This does three things: If you're on GCP, it adds a .internal DNS split route to the metadata server, so we never break GCP DNS names. This lets people have some Tailscale nodes on GCP and some not (e.g. laptops at home) without having to add a Tailnet-wide .internal DNS route. If you already have such a route, though, it won't overwrite it. * If the 100.100.100.100 DNS forwarder has nowhere to forward to, it forwards it to the GCP metadata IP, which forwards to 8.8.8.8. This means there are never errNoUpstreams ("upstream nameservers not set") errors on GCP due to e.g. mangled /etc/resolv.conf (GCP default VMs don't have systemd-resolved, so it's likely a DNS supremacy fight) * makes the DNS fallback mechanism use the GCP metadata IP as a fallback before our hosted HTTP-based fallbacks I created a default GCP VM from their web wizard. It has no systemd-resolved. I then made its /etc/resolv.conf be empty and deleted its GCP hostnames in /etc/hosts. I then logged in to a tailnet with no global DNS settings. With this, tailscaled writes /etc/resolv.conf (direct mode, as no systemd-resolved) and sets it to 100.100.100.100, which then has regular DNS via the metadata IP and .internal DNS via the metadata IP as well. If the tailnet configures explicit DNS servers, those are used instead, except for .internal. This also adds a new util/cloudenv package based on version/distro where the cloud type is only detected once. We'll likely expand it in the future for other clouds, doing variants of this change for other popular cloud environments.

Brad Fitzpatrick	cc575fe4d6	net/dns: schedule DoH upgrade explicitly, fix Resolver.Addr confusion Two changes in one: * make DoH upgrades an explicitly scheduled send earlier, when we come up with the resolvers-and-delay send plan. Previously we were getting e.g. four Google DNS IPs and then spreading them out in time (for back when we only did UDP) but then later we added DoH upgrading at the UDP packet layer, which resulted in sometimes multiple DoH queries to the same provider running (each doing happy eyeballs dialing to 4x IPs themselves) for each of the 4 source IPs. Instead, take those 4 Google/Cloudflare IPs and schedule 5 things: first the DoH query (which can use all 4 IPs), and then each of the 4 IPs as UDP later. * clean up the dnstype.Resolver.Addr confusion; half the code was using it as an IP string (as documented) as half was using it as an IP:port (from some prior type we used), primarily for tests. Instead, document it was being primarily an IP string but also accepting an IP:port for tests, then add an accessor method on it to get the IPPort and use that consistently everywhere.

Maisem Ali	50b4b8b2c6	ipn/ipnlocal: make peerIPs return a sorted slice Currently peerIPs doesn't do any sorting of the routes it returns. This is typically fine, however imagine the case of an HA subnet router failover. When a route R moves from peer A to peer B, the output of peerIPs changes. This in turn causes all the deephash check inside wgengine to fail as the hashed value of [R1, R2] is different than the hashed value of [R2, R1]. When the hash check failes, it causes wgengine to reconfigure all routes in the OS. This is especially problematic for macOS and iOS where we use the NetworkExtension. This commit makes it that the peerIPs are always sorted when returned, thus making the hash be consistent as long as the list of routes remains static.

Brad Fitzpatrick	bd90781b34	ipn/ipnlocal, wgengine/netstack: use netstack for peerapi server We're finding a bunch of host operating systems/firewalls interact poorly with peerapi. We either get ICMP errors from the host or users need to run commands to allow the peerapi port: https://github.com/tailscale/tailscale/issues/3842#issuecomment-1025133727 ... even though the peerapi should be an internal implementation detail. Rather than fight the host OS & firewalls, this change handles the server side of peerapi entirely in netstack (except on iOS), so it never makes its way to the host OS where it might be messed with. Two main downsides are: 1) netstack isn't as fast, but we don't really need speed for peerapi. And actually, with fewer trips to/from the kernel, we might actually make up for some of the netstack performance loss by staying in userspace. 2) tcpdump / Wireshark etc packet captures will no longer see the peerapi traffic. Oh well. Crawshaw's been wanting to add packet capture server support to tailscaled, so we'll probably do that sooner now. A future change might also then use peerapi for the client-side (except on iOS).

Brad Fitzpatrick	c37af58ea4	net/tsdial: move more weirdo dialing into new tsdial package, plumb Not done yet, but this move more of the outbound dial special casing from random packages into tsdial, which aspires to be the one unified place for all outbound dialing shenanigans. Then this plumbs it all around, so everybody is ultimately holding on to the same dialer. As of this commit, macOS/iOS using an exit node should be able to reach to the exit node's DoH DNS proxy over peerapi, doing the sockopt to stay within the Network Extension. A number of steps remain, including but limited to: * move a bunch more random dialing stuff * make netstack-mode tailscaled be able to use exit node's DNS proxy, teaching tsdial's resolver to use it when an exit node is in use.

Avery Pennarun	eaa6507cc9	ipnlocal: in Start() fast path, don't forget to send Prefs. The resulting empty Prefs had AllowSingleHosts=false and Routeall=false, so that on iOS if you did these steps: - Login and leave running - Terminate the frontend - Restart the frontend (fast path restart, missing prefs) - Set WantRunning=false - Set WantRunning=true ...then you would have Tailscale running, but with no routes. You would also accidentally disable the ExitNodeID/IP prefs (symptom: the current exit node setting didn't appear in the UI), but since nothing else worked either, you probably didn't notice. The fix was easy enough. It turns out we already knew about the problem, so this also fixes one of the BUG entries in state_test. Fixes: #1918 (BUG-1) and some as-yet-unreported bugs with exit nodes.

Avery Pennarun	8a7d35594d	ipnlocal: don't assume NeedsLogin immediately after StartLogout(). Previously, there was no server round trip required to log out, so when you asked ipnlocal to Logout(), it could clear the netmap immediately and switch to NeedsLogin state. In v1.8, we added a true Logout operation. ipn.Logout() would trigger an async cc.StartLogout() and also immediately switch to NeedsLogin. Unfortunately, some frontends would see NeedsLogin and immediately trigger a new StartInteractiveLogin() operation, before the controlclient auth state machine actually acted on the Logout command, thus accidentally invalidating the entire logout operation, retaining the netmap, and violating the user's expectations. Instead, add a new LogoutFinished signal from controlclient (paralleling LoginFinished) and, upon starting a logout, don't update the ipn state machine until it's received.

Avery Pennarun	6fd4e8d244	ipnlocal: fix switching users while logged in + Stopped. This code path is very tricky since it was originally designed for the "re-authenticate to refresh my keys" use case, which didn't want to lose the original session even if the refresh cycle failed. This is why it acts differently from the Logout(); Login(); case. Maybe that's too fancy, considering that it probably never quite worked at all, for switching between users without logging out first. But it works now. This was more invasive than I hoped, but the necessary fixes actually removed several other suspicious BUG: lines from state_test.go, so I'm pretty confident this is a significant net improvement.

Avery Pennarun	6d10655dc3	ipnlocal: accept a new opts.UpdatePrefs field. This is needed because the original opts.Prefs field was at some point subverted for use in frontend->backend state migration for backward compatibility on some platforms. We still need that feature, but we also need the feature of providing the full set of prefs from `tailscale up`, not including overwriting the prefs.Persist keys, so we can't use the original field from `tailscale up`. `tailscale up` had attempted to compensate for that by doing SetPrefs() before Start(), but that violates the ipn.Backend contract, which says you should call Start() before anything else (that's why it's called Start()). As a result, doing SetPrefs({ControlURL=..., WantRunning=true}) would cause a connection to the previous control server (because WantRunning=true), and then connect to the new control server only after running Start(). This problem may have been avoided before, but only by pure luck. It turned out to be relatively harmless since the connection to the old control server was immediately closed and replaced anyway, but it created a race condition that could have caused spurious notifications or rejected keys if the server responded quickly. As already covered by existing TODOs, a better fix would be to have Start() get out of the business of state migration altogether. But we're approaching a release so I want to make the minimum possible fix. Fixes #1840. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	5 years ago

Avery Pennarun	4ef207833b	ipn: !WantRunning + !LoggedOut should not be idle on startup. There was logic that would make a "down" tailscale backend (ie. !WantRunning) refuse to do any network activity. Unfortunately, this makes the macOS and iOS UI unable to render correctly if they start while !WantRunning. Now that we have Prefs.LoggedOut, use that instead. So `tailscale down` will still allow the controlclient to connect its authroutine, but pause the maproutine. `tailscale logout` will entirely stop all activity. This new behaviour is not obviously correct; it's a bit annoying that `tailsale down` doesn't terminate all activity like you might expect. Maybe we should redesign the UI code to render differently when disconnected, and then revert this change. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	5 years ago
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.

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.

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.
