Brad Fitzpatrick	01ee638cca	Change some os.IsNotExist to errors.Is(err, os.ErrNotExist) for non-os errors. os.IsNotExist doesn't unwrap errors. errors.Is does. The ioutil.ReadFile ones happened to be fine but I changed them so we're consistent with the rule: if the error comes from os, you can use os.IsNotExist, but from any other package, use errors.Is. (errors.Is always would also work, but not worth updating all the code) The motivation here was that we were logging about failure to migrate legacy relay node prefs file on startup, even though the code tried to avoid that. See golang/go#41122	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	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

Elias Naur	364a8508b2	ipn: add Hostname override to Prefs Overriding the hostname is required for Android, where os.Hostname is often just "localhost". Updates #409 Signed-off-by: Elias Naur <mail@eliasnaur.com>	5 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	bfdc8175b1	wgengine/router: add a setting to disable SNAT for subnet routes. Part of #320. Signed-off-by: David Anderson <danderson@tailscale.com>	5 years ago
Avery Pennarun	9d1f48032a	cmd/tailscale: add --advertise-tags option. These will be used for dynamically changing the identity of a node, so its ACL rights can be different from your own. Note: Not all implemented yet on the server side, but we need this so we can request the tagged rights in the first place. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	5 years ago
Avery Pennarun	d7429b9a8d	Add prefs.ShieldsUp and --shields-up option. This sets a default packet filter that blocks all incoming requests, giving end users more control over who can get into their machine, even if the admin hasn't set any central ACLs.

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	a5b84fa921	ipn: add AdvertiseRoutes to Prefs. This is a prelude to supporting relaynode's --routes in tailscaled. The daemon needs to remembers routes to advertise, and the CLI needs to be able to change the set of advertised routes. Prefs is the thing used for both of these.
