Brad Fitzpatrick	6b1d2a5630	ipn: don't set DebugFlags to len 1 slice of empty string [""] Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
David Anderson	62d941dc26	tailcfg: add a DebugFlags field for experiments and debugging. Also replaces the IPv6Overlay bool with use of DebugFlags, since it's currently an experimental configuration. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
Brad Fitzpatrick	1fd9958e9d	ipn: wait for initial portpoll result before starting controlclient We were creating the controlclient and starting the portpoll concurrently, which frequently resulted in the first controlclient connection being canceled by the firsdt portpoll result ~milliseconds later, resulting in another HTTP request. Instead, wait a bit for the first portpoll result so it's much less likely to interrupt our controlclient connection. Updates tailscale/corp#557	4 years ago
Brad Fitzpatrick	515866d7c6	ipn, ipnserver, cmd/tailscale: add "server mode" support on Windows This partially (but not yet fully) migrates Windows to tailscaled's StateStore storage system. This adds a new bool Pref, ForceDaemon, defined as: // ForceDaemon specifies whether a platform that normally // operates in "client mode" (that is, requires an active user // logged in with the GUI app running) should keep running after the // GUI ends and/or the user logs out. // // The only current applicable platform is Windows. This // forced Windows to go into "server mode" where Tailscale is // running even with no users logged in. This might also be // used for macOS in the future. This setting has no effect // for Linux/etc, which always operate in daemon mode. Then, when ForceDaemon becomes true, we now write use the StateStore to track which user started it in server mode, and store their prefs under that key. The ipnserver validates the connections/identities and informs that LocalBackend which userid is currently in charge. The GUI can then enable/disable server mode at runtime, without using the CLI. But the "tailscale up" CLI was also fixed, so Windows users can use authkeys or ACL tags, etc. Updates #275	4 years ago
Brad Fitzpatrick	6ee219a25d	ipn, wgengine, magicsock, tsdns: be quieter and less aggressive when offline If no interfaces are up, calm down and stop spamming so much. It was noticed as especially bad on Windows, but probably was bad everywhere. I just have the best network conditions testing on a Windows VM. Updates #604	4 years ago
Brad Fitzpatrick	587bdc4280	ipn, wgengine: disable subnet routes if network has PAC configuration Not configurable yet. Updates tailscale/corp#653 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	12e28aa87d	ipn: on transition from no PAC to PAC, reset state So previous routes aren't shadowing resources that the operating system might need (Windows Domain Controller, DNS server, corp HTTP proxy, WinHTTP fetching the PAC file itself, etc). This effectively detects when we're transitioning from, say, public wifi to corp wifi and makes Tailscale remove all its routes and stops its TCP connections and tries connecting to everything anew. Updates tailscale/corp#653	4 years ago
Brad Fitzpatrick	b5a3850d29	control/controlclient, ipn: store machine key separately from user prefs/persist Updates #610 (fixes after some win/xcode changes in a separate repo)	4 years ago
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
Josh Bleecher Snyder	e5894aba42	all: keep UserProfiles a slice instead of a map for longer Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	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	3af64765fd	ipn: fix Windows crash from improperly strict assertion	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

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.

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	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	666d404066	ipn: put discovery key generation behind an environment flag for now Later we'll want to use the presence of a discovery key as a signal that the node knows how to participate in discovery. Currently the code generates keys and sends them to the control server but doesn't do anything with them, which is a bad state to stay in lest we release this code and end up with nodes in the future that look like they're functional with the new discovery protocol but aren't. So for now, make this opt-in as a debug option for now, until the rest of it is in. Updates #483	5 years ago
