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	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	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
Josh Bleecher Snyder	e8cd7bb66f	tstest: simplify goroutine leak tests Use tb.Cleanup to simplify both the API and the implementation. One behavior change: When the number of goroutines shrinks, don't log. I've never found these logs to be useful, and they frequently add noise.

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`.

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
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>	5 years ago

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	cf1e386cbd	ipn: move Options.ServerURL into Prefs. We can't rely on a frontend to provide a control server URL, so this naturally belongs in server-persisted state. Signed-off-by: David Anderson <dave@natulte.net>	5 years ago
David Anderson	21280ca2d1	Make ipn.Options.Prefs a pointer. This is a prelude to making it truly optional, once state management has moved into the backend. For now though, it's still required. This change is just isolating the bubbling-up of the pointerification into other layers. Signed-Off-By: David Anderson <dave@natulte.net>	5 years ago
