Brad Fitzpatrick	c8f257df00	Revert "all: keep UserProfiles a slice instead of a map for longer" This reverts commit `e5894aba42`. Breaks macOS/iOS build. Reverting per chat with Josh; he'll fix later today.	4 years ago
Brad Fitzpatrick	90b7293b3b	ipn: add/move some constants, update a comment And make the StateStore implementations be Stringers, for error messages.	4 years ago

Brad Fitzpatrick	3bdcfa7193	ipn: remove DisableDERP pref We depend on DERP for NAT traversal now[0] so disabling it entirely can't work. What we'll do instead in the future is let people specify alternate/additional DERP servers. And perhaps in the future we could also add a pref for nodes to say when they expect to never need/want to use DERP for data (but allow it for NAT traversal communication). But this isn't the right pref and it doesn't work, so delete it. Fixes #318 [0] https://tailscale.com/blog/how-nat-traversal-works/	4 years ago
Brad Fitzpatrick	c41947903a	ipn: don't log if legacy prefs don't exist (the normal case these days)	4 years ago
Brad Fitzpatrick	96fd20e3c0	ipn: bail out a bit earlier when a peer doesn't have a DNS name It's properly handled later in tsdns.NewMap anyway, but there's work done in the meantime that can be skipped when a peer lacks a DNS name. It's also more clear that it's okay for it to be blank.	4 years ago
David Anderson	8f5b52e571	net/netns: add windows support. Also remove rebinding logic from the windows router. Magicsock will instead rebind based on link change signals. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
Brad Fitzpatrick	4f71319f7c	ipn/ipnserver: make ipnserver also be an HTTP server for localhost clients For now it just says hello to show auth works. More later.	4 years ago
Brad Fitzpatrick	3af64765fd	ipn: fix Windows crash from improperly strict assertion	4 years ago
Brad Fitzpatrick	8ecee476f6	ipn: simplify TestLocalLogLines, defer a Shutdown of its LocalBackend The test's LocalBackend was not shut down (Shutdown both releases resources and waits for its various goroutines to end). This should fix the test race we were seeing. It definitely fixes the file descriptor leak that preventing -race -count=500 from passing before.	4 years ago
Brad Fitzpatrick	68c42530e9	tstest: rename LogListener to LogLineTracker But mostly to rename tstest.ListenFor which has no mention of log lines in it. It sounded like a net.Listener or something.	4 years ago
Brad Fitzpatrick	9b07517f18	wgengine: add Engine.SetLinkChangeCallback Start of making the IPN state machine react to link changes and down its DNS & routes if necessary to unblock proxy resolution (e.g. for transitioning from public to corp networks where the corp network has mandatory proxies and WPAD PAC files that can't be resolved while using the DNS/routes configured previously) This change should be a no-op. Just some callback plumbing.	4 years ago

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.

David Anderson	d64de1ddf7	Revert "cmd/tailscaled: exit gracefully on SIGPIPE" tailscaled receives a SIGPIPE when CLIs disconnect from it. We shouldn't shut down in that case. This reverts commit `43b271cb26`. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	358cd3fd92	ipn: fix incorrect change tracking for packet filter. ORder of operations to trigger a problem: - Start an already authed tailscaled, verify you can ping stuff. - Run `tailscale up`. Notice you can no longer ping stuff. The problem is that `tailscale up` stops the IPN state machine before restarting it, which zeros out the packet filter but _not_ the packet filter hash. Then, upon restarting IPN, the uncleared hash incorrectly makes the code conclude that the filter doesn't need updating, and so we stay with a zero filter (reject everything) for ever. The fix is simply to update the filterHash correctly in all cases, so that running -> stopped -> running correctly changes the filter at every transition.

Brad Fitzpatrick	4aba86cc03	ipn/ipnserver: make Engine argument a func that tries again for each connection So a backend in server-an-error state (as used by Windows) can try to create a new Engine again each time somebody re-connects, relaunching the GUI app. (The proper fix is actually fixing Windows issues, but this makes things better in the short term) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago

Elias Naur	6e8f0860af	ipn: add Login backend command for sign-in with token The StartLoginInteractive command is for delegating the sign-in flow to a browser. The Android Gooogle Sign-In SDK inverts the flow by giving the client ID tokens. Add a new backend command for accepting such tokens by exposing the existing controlclient.Client.Login support for OAuth2 tokens. Introduce a custom TokenType to distinguish ID tokens from other OAuth2 tokens. Signed-off-by: Elias Naur <mail@eliasnaur.com>	4 years ago

Brad Fitzpatrick	96d806789f	ipn: add Notify.LocalTCPPort field for macOS Network Extension to use We want the macOS Network Extension to share fate with the UI frontend, so we need the backend to know when the frontend disappears. One easy way to do that is to reuse the existing TCP server it's already running (for tailscale status clietns). We now tell the frontend our ephemeral TCP port number, and then have the UI connect to it, so the backend can know when it disappears. There are likely Swift ways of doing this, but I couldn't find them quickly enough, so I reached for the hammer I knew.	4 years ago

Dmytro Shynkevych	67ebba90e1	tsdns: dual resolution mode, IPv6 support (#526 ) This change adds to tsdns the ability to delegate lookups to upstream nameservers. This is crucial for setting Magic DNS as the system resolver. Signed-off-by: Dmytro Shynkevych <dmytro@tailscale.com>	4 years ago

Brad Fitzpatrick	630379a1d0	cmd/tailscale: add tailscale status region name, last write, consistently star There's a lot of confusion around what tailscale status shows, so make it better: show region names, last write time, and put stars around DERP too if active. Now stars are always present if activity, and always somewhere.	4 years ago
David Anderson	9cd4e65191	smallzstd: new package that constructs zstd small encoders/decoders. It's just a config wrapper that passes "use less memory at the expense of compression" parameters by default, so that we don't accidentally construct resource-hungry (de)compressors. Also includes a benchmark that measures the memory cost of the small variants vs. the stock variants. The savings are significant on both compressors (~8x less memory) and decompressors (~1.4x less, not including the savings from the significantly smaller window on the compression side - with those savings included it's more like ~140x smaller).

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
