Brad Fitzpatrick	d8cb5aae17	tailcfg, control/controlclient: add tailcfg.PeersChangedPatch [capver 33] ... This adds a lighter mechanism for endpoint updates from control. Change-Id: If169c26becb76d683e9877dc48cfb35f90cc5f24 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Brad Fitzpatrick	b7f1fe7b0d	tailcfg: remove old DNS fields ... The control plane server doesn't send these to modern clients so we don't need them in the tree. The server has its own serialization code to generate legacy MapResponses when needed.

Mihai Parparita	2990c2b1cf	control/controlhttp: use secure WebSockets protocol by default ... Forcing the insecure protocol (and perserving the port number) is only desired for localhost testing, in prod we need to use wss:// to avoid mixed-content errors.

Mihai Parparita	a9f32656f5	control/controlhttp: allow client and server to communicate over WebSockets ... We can't do Noise-over-HTTP in Wasm/JS (because we don't have bidirectional communication), but we should be able to do it over WebSockets. Reuses derp WebSocket support that allows us to turn a WebSocket connection into a net.Conn. Updates #3157 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	3 years ago

Maisem Ali	c60cbca371	control/controlclient: store netinfo and hostinfo separately ... Currently, when SetNetInfo is called it sets the value on hostinfo.NetInfo. However, when SetHostInfo is called it overwrites the hostinfo field which may mean it also clears out the NetInfo it had just received. This commit stores NetInfo separately and combines it into Hostinfo as needed so that control is always notified of the latest values. Also, remove unused copies of Hostinfo from ipn.Status and controlclient.Auto. Updates #tailscale/corp#4824 (maybe fixes) Signed-off-by: Maisem Ali <maisem@tailscale.com>	3 years ago

Brad Fitzpatrick	1237000efe	control/controlhttp: don't assume port 80 upgrade response will work ... Just because we get an HTTP upgrade response over port 80, don't assume we'll be able to do bi-di Noise over it. There might be a MITM corp proxy or anti-virus/firewall interfering. Do a bit more work to validate the connection before proceeding to give up on the TLS port 443 dial.

Maisem Ali	5a1ef1bbb9	net/tsdial: add SystemDial as a wrapper on netns.Dial ... The connections returned from SystemDial are automatically closed when there is a major link change. Also plumb through the dialer to the noise client so that connections are auto-reset when moving from cellular to WiFi etc. Updates #3363 Signed-off-by: Maisem Ali <maisem@tailscale.com>	3 years ago

James Tucker	c591c91653	tailcfg, control/controlclient: TSMP & disco pings ... tailcfg.PingResponse formalizes the TSMP & disco response message, and controlclient is wired to send POST responses containing tailcfg.PingResponse for TSMP and disco PingRequests. Updates tailscale/corp#754 Signed-off-by: James Tucker <james@tailscale.com>	3 years ago
David Anderson	f570372b4d	control/controlbase: don't enforce a max protocol version at handshake time. ... Doing so makes development unpleasant, because we have to first break the client by bumping to a version the control server rejects, then upgrade the control server to make it accept the new version. This strict rejection at handshake time is only necessary if we want to blocklist some vulnerable protocol versions in the future. So, switch to a default-permissive stance: until we have such a version that we have to eagerly block early, we'll accept whatever version the client presents, and leave it to the user of controlbase.Conn to make decisions based on that version. Noise still enforces that the client and server *agree* on what protocol version is being used, and the control server still has the option to finish the handshake and then hang up with an in-noise error, rather than abort at the handshake level. Updates #3488 Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	02ad987e24	control/controlbase: make the protocol version number selectable. ... This is so that we can plumb our client capability version through the protocol as the Noise version. The capability version increments more frequently than strictly required (the Noise version only needs to change when cryptographically-significant changes are made to the protocol, whereas the capability version also indicates changes in non-cryptographically-significant parts of the protocol), but this gives us a safe pre-auth way to determine if the client supports future protocol features, while still relying on Noise's strong assurance that the client and server have agreed on the same version. Currently, the server executes the same protocol regardless of the version number, and just presents the version to the caller so they can do capability-based things in the upper RPC protocol. In future, we may add a ratchet to disallow obsolete protocols, or vary the Noise handshake behavior based on requested version.

Josh Bleecher Snyder	26021b07ec	control/controlclient: only build certstore-related code with the Tailscale Go toolchain ... The certstore code is impacted by golang/go#51726. The Tailscale Go toolchain fork contains a temporary workaround, so it can compile it. Once the upstream toolchain can compile certstore, presumably in Go 1.18.1, we can revert this change.

Brad Fitzpatrick	d5f8f38ac6	tailcfg: rename map request version to "capability version" ... And add a CapabilityVersion type, primarily for documentation. This makes MapRequest.Version, RegisterRequest.Version, and SetDNSRequest.Version all use the same version, which will avoid confusing in the future if Register or SetDNS ever changed their semantics on Version change. (Currently they're both always 1) This will requre a control server change to allow a SetDNSRequest.Version value other than 1 to be deployed first.

David Anderson	d5a7eabcd0	control/controlbase: enable asynchronous client handshaking. ... With this change, the client can obtain the initial handshake message separately from the rest of the handshake, for embedding into another protocol.

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.

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.

Brad Fitzpatrick	2f04f49376	control/controlclient: use lite map request handler to avoid aborting streams ... Previously, any change to endpoints or hostinfo (or hostinfo's netinfo) would result in the long-running map request HTTP stream being torn down and restarted, losing all compression context along with it. This change makes us instead send a lite map request (OmitPeers: true, Stream: false) that doesn't subscribe to anything, and then the coordination server knows to not close other streams for that node when it recives a lite request.

Brad Fitzpatrick	e8ae355bb8	ipn: delete domainsForProxying, require explicit DNS search domains (mapver 9) (#1078) ... Previously the client had heuristics to calculate which DNS search domains to set, based on the peers' names. Unfortunately that prevented us from doing some things we wanted to do server-side related to node sharing. So, bump MapRequest.Version to 9 to signal that the client only uses the explicitly configured DNS search domains and doesn't augment it with its own list.

Josh Bleecher Snyder	56a7652dc9	wgkey: new package ... This is a replacement for the key-related parts of the wireguard-go wgcfg package. This is almost a straight copy/paste from the wgcfg package.

To avoid having wireguard-go depend on this new package, wgcfg will keep its key types. We translate into and out of those types at the last minute.

Brad Fitzpatrick	0e3048d8e0	control/controlclient: support delta userprofiles from control ... I was going to make support for this advertised from the client, but turns out only "tailscale status" even uses the UserProfiles field and fails gracefully (omits that field) if a user profile for a user is missing, so I think we can just reuse the DeltaPeers field from the client to ask the control server to also delta encode the user profiles. For the few users running 1.1.x (unstable) versions between DeltaPeers support (1.1.82) and this (~1.1.541), they'll just sometimes have missing names in "tailscale status --json" or "tailscale status --web" (the only places the UserProfile is used).	4 years ago
