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.

Adrian Dewhurst	6d6cf88d82	control/controlclient: use our fork of certstore ... The cyolosecurity fork of certstore did not update its module name and thus can only be used with a replace directive.

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>	5 years ago

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	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).	5 years ago

NetworkMap text diffs being empty were currently used to short-circuit calling magicsock's SetNetworkMap (via Engine.SetNetworkMap), but that went away in c7582dc2 (0.100.0-230) Prior to c7582dc2 (notably, in 0.100.0-225 and below, down to 0.100.0), a change in only disco key (as when a node restarts) but without endpoint changes (as would happen for a client not behind a NAT with random ports) could result in a "netmap diff: (none)" being printed, as well as Engine.SetNetworkMap being skipped, leading to broken discovery endpoints. c7582dc2 fixed the Engine.SetNetworkMap skippage. This change fixes the "netmap diff: (none)" print so we'll actually see when a peer restarts with identical endpoints but a new discovery key.	5 years ago

As a bonus, if you run a test using t.Run(), the log messages printed via the sub-t.Run() are printed at a different time from log messages printed via the parent t.Run(), making debugging almost impossible.

Avery Pennarun	08acb502e5	Add tstest.PanicOnLog(), and fix various problems detected by this. ... If a test calls log.Printf, 'go test' horrifyingly rearranges the output to no longer be in chronological order, which makes debugging virtually impossible. Let's stop that from happening by making log.Printf panic if called from any module, no matter how deep, during tests. This required us to change the default error handler in at least one http.Server, as well as plumbing a bunch of logf functions around, especially in magicsock and wgengine, but also in logtail and backoff. To add insult to injury, 'go test' also rearranges the output when a parent test has multiple sub-tests (all the sub-test's t.Logf is always printed after all the parent tests t.Logf), so we need to screw around with a special Logf that can point at the "current" t (current_t.Logf) in some places. Probably our entire way of using subtests is wrong, since 'go test' would probably like to run them all in parallel if you called t.Parallel(), but it definitely can't because the're all manipulating the shared state created by the parent test. They should probably all be separate toplevel tests instead, with common setup/teardown logic. But that's a job for another time. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	6 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.

David Crawshaw	0590ad68be	controlclient, ipn: adjust tests for authURL semantic changes ... The tests cheat at filling out web forms by directly POSTing to the target. The target for authURLs has changed slightly, the base authURL now redirects the user to the login page. Additionally, the authURL cycle now checks the cookie is set correctly, so we add cookie jars where necessary to pass the cookie through.	6 years ago

Avery Pennarun	b4897e7de8	controlclient/netmap: write our own b.ConciseDiffFrom(a) function. ... This removes the need for go-cmp, which is extremely bloaty so we had to leave it out of iOS. As a result, we had also left it out of macOS, and so we didn't print netmap diffs at all on darwin-based platforms. Oops. As a bonus, the output format of the new function is way better. Minor oddity: because I used the dumbest possible diff algorithm, the sort order is a bit dumb. We print all "removed" lines and then print all "added" lines, rather than doing the usual diff-like thing of interspersing them. This probably doesn't matter (maybe it's an improvement).	6 years ago
Avery Pennarun	96bb05ce2f	controlclient: reformat netmap.Concise() and add DERP server info. ... The .Concise() view had grown hard to read over time. Originally, we assumed a peer almost always had just one endpoint and one-or-more allowedips. With magicsock, we now almost always have multiple endpoints per peer. And empirically, almost every peer has only one allowedip. Change their order so we can line up allowedips vertically. Also do some tweaking to make multiple endpoints easier to read. While we're here, add a column to show the home DERP server of each peer, if any.	6 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.	6 years ago
