Brad Fitzpatrick	a6c34bdc28	control/controlclient: also include our own profile (for when no self-owned peers) ... Fix from regression in previous commit (0e3048d8e0) that was caught by e2e tests. In that previous commit, the user's own profile was omitted from the NetworkMap in the case where the user only had one node.	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	82f2fdc194	control/controlclient: adjust some logging point names ... The previous code read too explicitly like log.Printf("I am here1"), log.Printf("I am here2"). It still is with this change, but prettier, and less subject to code rearranging order.	4 years ago
Brad Fitzpatrick	1819f6f8c8	control/controlclient: set MapRequest.ReadOnly on initial empty endpoint request ... On startup, clients do a MapRequest with empty endpoints while they learn the DERP map to discover the STUN servers they then query to learn their endpoints. Set MapRequest.ReadOnly on those initial queries to not broadcast the empty endpoints out to peers. The read results will come a half second later (or less). Updates tailscale/corp#557	4 years ago
Avery Pennarun	6332bc5e08	controlclient: print http errors if result code != 200. ... Turns out for the particular error I was chasing, it actually returns 200 and zero data. But this code mirrors the same check in the map poll, and is the right thing to do in the name of future debugging. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	4 years ago

Brad Fitzpatrick	904a91038a	tailcfg: add MapRequest.ReadOnly and OmitPeers; remove DebugForceDisco ... DebugForceDisco was a development & safety knob during the the transition to discovery. It's no longer needed. Add MapRequest.ReadOnly to prevent clients needing to do two peer-spamming MapRequest at start-up. This only adds the field, not the use of the field. (The control server needs to support it first.) Updates tailscale/corp#557 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago

Brad Fitzpatrick	6298018704	control/controlclient: print disco keys NetworkMap diffs (debug change only) ... 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.	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	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.

Avery Pennarun	8f8607b6bf	control/controlclient/auto_test: clean up logging to defeat 'go test' idiocy. ... By default, nothing differentiates errors or fatals from regular logs, so they just blend into the rest of the logs. 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. This doesn't actually fix the test flake I'm looking for, but at least I can find it in the logs now. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	4 years ago

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>	4 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.

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).	4 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.	4 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.	4 years ago
