julianknodt	1bb6abc604	net/portmapper: add upnp port mapping Add in UPnP portmapping, using goupnp library in order to get the UPnP client and run the portmapping functions.

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	1bd14a072c	cmd/tailscale, ipn/localapi: move IP forwarding check to tailscaled, API Instead of having the CLI check whether IP forwarding is enabled, ask tailscaled.

Adrian Dewhurst	04dd6d1dae	control/controlclient: sign RegisterRequest (#1549 ) control/controlclient: sign RegisterRequest Some customers wish to verify eligibility for devices to join their tailnets using machine identity certificates. TLS client certs could potentially fulfill this role but the initial customer for this feature has technical requirements that prevent their use. Instead, the certificate is loaded from the Windows local machine certificate store and uses its RSA public key to sign the RegisterRequest message. There is room to improve the flexibility of this feature in future and it is currently only tested on Windows (although Darwin theoretically works too), but this offers a reasonable starting place for now.

Brad Fitzpatrick	f45a9e291b	tailcfg, control/controlclient: add MapResponse.PingRequest So the control server can test whether a client's actually present.

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. I have slightly changed some of the exported functions and types to avoid stutter, added and tweaked some comments, and removed some now-unused code. 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. These few remaining uses will be eliminated alongside the rest of the wgcfg package. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago

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

Brad Fitzpatrick	6233fd7ac3	control/controlclient: don't truncate AuthURL in log It's useful to copy/paste directly from there, without using tailscale up. If it's truncated for some specific reason, it doesn't say why.	4 years ago
Brad Fitzpatrick	a975e86bb8	wgengine/magicsock: add new endpoint type used for discovery-supporting peers This adds a new magicsock endpoint type only used when both sides support discovery (that is, are advertising a discovery key). Otherwise the old code is used. So far the new code only communicates over DERP as proof that the new code paths are wired up. None of the actually discovery messaging is implemented yet. Support for discovery (generating and advertising a key) are still behind an environment variable for now. Updates #483	4 years ago

Brad Fitzpatrick	b8edb7a5e9	control/controlclient: add Debug field to NetworkMap As part of disabling background STUN packets when idle, we want an emergency override switch to turn it back on, in case it interacts poorly in the wild.

Brad Fitzpatrick	e6b84f2159	all: make client use server-provided DERP map, add DERP region support Instead of hard-coding the DERP map (except for cmd/tailscale netcheck for now), get it from the control server at runtime. And make the DERP map support multiple nodes per region with clients picking the first one that's available. (The server will balance the order presented to clients for load balancing) This deletes the stunner package, merging it into the netcheck package instead, to minimize all the config hooks that would've been required. Also fix some test flakes & races. Fixes #387 (Don't hard-code the DERP map) Updates #388 (Add DERP region support) Fixes #399 (wgengine: flaky tests) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago

Avery Pennarun	65fbb9c303	wgengine/filter: support subnet mask rules, not just /32 IPs. This depends on improved support from the control server, to send the new subnet width (Bits) fields. If these are missing, we fall back to assuming their value is /32. Conversely, if the server sends Bits fields to an older client, it will interpret them as /32 addresses. Since the only rules we allow are "accept" rules, this will be narrower or equal to the intended rule, so older clients will simply reject hosts on the wider subnet (fail closed). With this change, the internal filter.Matches format has diverged from the wire format used by controlclient, so move the wire format into tailcfg and convert it to filter.Matches in controlclient.

Brad Fitzpatrick	eb6de2bd88	control/controlclient: restore Options.HTTPC as Options.HTTPTestClient I removed the HTTPC field in `b6fa5a69be` but it was apparently still used in [oss-skipped] tests. Restore it, but name it so it's more obvious that it's only for tests. (It currently is, and I'd like to keep it like that for now.)	5 years ago

Avery Pennarun	f2e2ffa423	controlclient: log the entire netmap up to every 5 minutes. We log it once upon receiving the first copy of the map, then subsequently when a new one appears, but only if we haven't logged one less than 5 minutes ago. This avoids overly cluttering the log (as we did before, logging the netmap every time one appeared, which could be hundreds of lines every few seconds), but still gives the log enough context to help in diagnosing problems retroactively.	5 years ago
