Brad Fitzpatrick	dd97111d06	backoff: update to Go style, document a bit, make 30s explicit Also, bit of behavior change: on non-nil err but expired context, don't reset the consecutive failure count. I don't think the old behavior was intentional. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	696020227c	tailcfg, control/controlclient: support delta-encoded netmaps Should greatly reduce bandwidth for large networks (including our hello.ipn.dev node). Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	5590daa97d	control/controlclient: reset timeout timer on non-keepalive map updates Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	41c4560592	control/controlclient: remove unused NetworkMap.UAPI method And remove last remaining use of wgcfg.ToUAPI in a test's debug output; replace it with JSON.	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	be3ca5cbfd	control/controlclient: remove unused, slow, often-not-what-you-want NetworkMap.Equal	4 years ago
Brad Fitzpatrick	05a79d79ae	control/controlclient: rewrite, test NetworkMap.ConciseDiffFrom It stood out a lot in hello.ipn.dev's profiles for generating a lot of garbage (and thus GC CPU).	4 years ago
Brad Fitzpatrick	3b0514ef6d	control/controlclient: rename uflags, give it a type, remove dead code	4 years ago
Brad Fitzpatrick	32ecdea157	control/controlclient: generate wireguard config w/o WgQuick text indirection	4 years ago
Dmytro Shynkevych	d361511512	control/controlclient: eliminate race in loginGoal access. This code is currently racy due to an incorrect assumption that goal is never modified in-place, so does not require extra locking. This change makes the assumption correct. Signed-off-by: Dmytro Shynkevych <dmytro@tailscale.com>	4 years ago
Brad Fitzpatrick	96994ec431	control/controlclient: fix a couple more data races	4 years ago
Brad Fitzpatrick	a8b95571fb	ipn, control/controlclient: fix some data races More remain. Fixes tailscale/corp#432	4 years ago
Brad Fitzpatrick	c9089c82e8	control/controlclient, tailcfg: turn active route discovery on by default Updates #483	4 years ago
Brad Fitzpatrick	57e8931160	control/controlclient: fix copy/paste-o in debug knob accessor Introduced in `a975e86bb8`. Only affected TS_DEBUG_* env users.	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	72bfea2ece	control/controlclient: remove IPv6 opt-out environment variable It was temporary and 3 months has elapsed without problems.	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. We'll send that via control, but we'll want to plumb it down to magicsock via NetworkMap. Updates tailscale/corp#320 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	36e9cb948f	control/controlclient: cut down some NetworkMap stringification & diff allocations And start of tests.	4 years ago
Brad Fitzpatrick	894e3bfc96	control/controlclient: trim /32 suffix a bit more succinctly	4 years ago

Brad Fitzpatrick	24009241bf	net/netns: move SOCKS dialing to netns for now This lets control & logs also use SOCKS dials. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago

Brad Fitzpatrick	f0204098d8	Revert "control/controlclient: use "getprop net.hostname" for Android hostname" This reverts commit `afb9c6a6ab`. Doesn't work. See: https://github.com/tailscale/tailscale/issues/409#issuecomment-635241550 Looks pretty dire: https://medium.com/capital-one-tech/how-to-get-an-android-device-nickname-d5eab12f4ced Updates #409	5 years ago

David Anderson	557b310e67	control/controlclient: move auto_test back to corp repo. It can't run without corp stuff anyway, and makes it harder to refactor the control server.	5 years ago
David Anderson	7317e73bf4	control/controlclient: move direct_test back to corp repo. It can only be built with corp deps anyway, and having it split from the control code makes our lives harder. Signed-off-by: David Anderson <danderson@tailscale.com>	5 years ago
Brad Fitzpatrick	703d789005	tailcfg: add MapResponse.Debug mechanism to trigger logging heap pprof Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 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. 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	c5fcc38bf1	controlclient tests: fix more memory leaks and add resource checking. I can now run these tests with -count=1000 without running out of RAM. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	5 years ago
Avery Pennarun	d03de31404	controlclient/direct: fix a race condition accessing auth keys. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	5 years ago
Avery Pennarun	1013cda799	controlclient/auto_test: don't print the s.control object. This contains atomic ints that trigger a race check error if we access them non-atomically. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	5 years ago
Avery Pennarun	d0754760e7	controlclient/auto_test: fix flake "peer OS is not linux" on macOS. We were mis-counting the number of Synchronized messages that we should have been generating.	5 years ago
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>	5 years ago
Avery Pennarun	286f96e412	control/controlclient: fix a very rare httptest.Server log.Printf. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	5 years ago
