Brad Fitzpatrick	3e1f2d01f7	ipn/ipnlocal: move Ping method from IPN bus to LocalBackend (HTTP) Change-Id: I61759f1dae8d9d446353db54c8b1e13bfffb3287 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
James Tucker	ae483d3446	wgengine, net/packet, cmd/tailscale: add ICMP echo Updates tailscale/corp#754 Signed-off-by: James Tucker <james@tailscale.com>	3 years ago
Mihai Parparita	2ec371fe8b	ipn: remove FakeExpireAfter Backend function No callers remain (last one was removed with tailscale/corp@1c095ae08f), and it's pretty esoteric. Signed-off-by: Mihai Parparita <mihai@tailscale.com>	3 years ago
Brad Fitzpatrick	3601b43530	ipn: add IPCVersion override func I've done this a handful of times in the past and again today. Time to make it a supported thing for the future. Used while debugging tailscale/corp#4559 (macsys CLI issues) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
David Anderson	1eabb5b2d9	ipn: don't log IPN messages that may contain an authkey. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Crawshaw	293a2b11cd	ipn: allow b to be nil in NewBackendServer A couple of code paths in ipnserver use a NewBackendServer with a nil backend just to call the callback with an encapsulated error message. This covers a panic case seen in logs. For #1920 Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	4 years ago
Brad Fitzpatrick	366b3d3f62	ipn{,/ipnserver}: delay JSON marshaling of ipn.Notifies If nobody is connected to the IPN bus, don't burn CPU & waste allocations (causing more GC) by encoding netmaps for nobody. This will notably help hello.ipn.dev. Updates tailscale/corp#1773 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	8a449c4dcd	ipn: define NewBackendServer nil as not affecting Backend's NotifyCallback Updates tailscale/corp#1646 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	f99e63bb17	ipn: don't Logout when Windows GUI disconnects Logout used to be a no-op, so the ipnserver previously synthensized a Logout on disconnect. Now that Logout actually invalidates the node key that was forcing all GUI closes to log people out. Instead, add a method to LocalBackend to specifically mean "the Windows GUI closed, please forget all the state". Fixes tailscale/corp#1591 (ignoring the notification issues, tracked elsewhere) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	d9ee9a0d3f	ipn: set BackendServer's notify earlier; don't require Start We've been slowly making Start less special and making IPN a multi-connection "watch" bus of changes, but this Start specialness had remained.

Brad Fitzpatrick	00d641d9fc	ipn/localapi: move EditPrefs to localapi Follow-up/revision to recent `53cfff109b` which added EditPrefs. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	799973a68d	ipn: move Options.Notify to its own method We already had SetNotifyCallback elsewhere on controlclient, so use that name. Baby steps towards some CLI refactor work. Updates tailscale/tailscale#1436	4 years ago
Brad Fitzpatrick	53cfff109b	ipn: replace SetWantRunning(bool) with EditPrefs(MaskedPrefs) This adds a new ipn.MaskedPrefs embedding a ipn.Prefs, along with a bunch of "has bits", kept in sync with tests & reflect. Then it adds a Prefs.ApplyEdits(MaskedPrefs) method. Then the ipn.Backend interface loses its weirdo SetWantRunning(bool) method (that I added in `483141094c` for "tailscale down") and replaces it with EditPrefs (alongside the existing SetPrefs for now). Then updates 'tailscale down' to use EditPrefs instead of SetWantRunning. In the future, we can use this to do more interesting things with the CLI, reconfiguring only certain properties without the reset-the-world "tailscale up".

Brad Fitzpatrick	0a02aaf813	control, ipn, tailcfg: remove golang.org/x/oauth2 dep, add tailcfg.Oauth2Token golang.org/x/oauth2 pulls in App Engine and grpc module dependencies, screwing up builds that depend on this module. Some background on the problem: https://go.googlesource.com/proposal/+/master/design/36460-lazy-module-loading.md Fixes tailscale/corp#1471 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	d0dffe33c0	cmd/tailscale, ipn/localapi: use localapi for status, not IPN acrobatics Yay simpler code. Tested on Linux, macOS and Windows. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	c7d4bf2333	cmd/tailscale/cli: recommend sudo for 'tailscale up' on failure Fixes #1220	4 years ago
Brad Fitzpatrick	5611f290eb	ipn, ipnserver: only require sudo on Linux for mutable CLI actions This partially reverts `d6e9fb1df0`, which modified the permissions on the tailscaled Unix socket and thus required "sudo tailscale" even for "tailscale status". Instead, open the permissions back up (on Linux only) but have the server look at the peer creds and only permit read-only actions unless you're root. In the future we'll also have a group that can do mutable actions. On OpenBSD and FreeBSD, the permissions on the socket remain locked down to 0600 from `d6e9fb1df0`.

Brad Fitzpatrick	20a357b386	ipn, ipn/ipnserver: add IPN state for server in use, handle explicitly On Windows, we were previously treating a server used by different users as a fatal error, which meant the second user (upon starting Tailscale, explicitly or via Start Up programs) got an invasive error message dialog. Instead, give it its own IPN state and change the Notify.ErrMessage to be details in that state. Then the Windows GUI can be less aggresive about that happening. Also, * wait to close the IPN connection until the server ownership state changes so the GUI doesn't need to repeatedly reconnect to discover changes. * fix a bug discovered during testing: on system reboot, the ipnserver's serverModeUser was getting cleared while the state transitioned from Unknown to Running. Instead, track 'inServerMode' explicitly and remove the old accessor method which was error prone. * fix a rare bug where the client could start up and set the server mode prefs in its Start call and we wouldn't persist that to the StateStore storage's prefs start key. (Previously it was only via a prefs toggle at runtime)	4 years ago
David Anderson	54e6c3a290	version: use OSS repo's version when building. When building with redo, also include the git commit hash from the proprietary repo, so that we have a precise commit that identifies all build info (including Go toolchain version). Add a top-level build script demonstrating to downstream distros how to burn the right information into builds. Adjust `tailscale version` to print commit hashes when available. Fixes #841.

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	3984f9be2f	ipn, ipn/ipnserver: add support for serving in error-message-only mode So Windows service failures can be propagated to the Windows UI client.	4 years ago
Brad Fitzpatrick	529e2cb31a	ipn: add AllowVersionSkew bool to Notify & Message For "tailscale status" on macOS (from separately downloaded cmd/tailscale binary against App Store IPNExtension). (This isn't all of it, but I've had this sitting around uncommitted.)	5 years ago
Brad Fitzpatrick	fefd7e10dc	types/structs: add structs.Incomparable annotation, use it where applicable Shotizam before and output queries: sqlite> select sum(size) from bin where func like 'type..%'; 129067 => 120216	5 years ago
Avery Pennarun	dbc1f71e5d	ipn/message: fix some message encoding problems. - Reset() was not including a Version field, so was getting rejected; the Logout operation no longer happened when the client got disconnected. - Don't crash if we can't decode 0-byte messages, which I suspect might sometimes come through on EOF.

David Anderson	c47f907a27	ipn: use *Prefs rather than Prefs throughout. Prefs has become a heavy object with non-memcpy copy semantics. We should not pass such a thing by value. Signed-off-by: David Anderson <dave@natulte.net>	5 years ago
David Anderson	62fb652eef	cmd/tailscaled: run off internal state autonomously. With this change, tailscaled can be restarted and reconnect without interaction from `tailscale`, and `tailscale` is merely there to provide login assistance and adjust preferences.
