Brad Fitzpatrick	cb4a2c00d1	ipn: remove unused Prefs.OSVersion and Prefs.DeviceModel iOS and Android no longer use these. They both now (as of today) use the hostinfo.SetFoo setters instead. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	67e5fabdbd	hostinfo, ipn/ipnlocal: add SetPackage, remove ipnlocal hacks Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	81269fad28	hostinfo: add SetOSVersion like SetDeviceModel, deprecate ipn.Prefs way Turns out the iOS client has been only sending the OS version it first started at. This whole hostinfo-via-prefs mechanism was never a good idea. Start removing it. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago

Brad Fitzpatrick	6d43cbc325	ipn/ipnlocal: make sure mobile clients don't use the old control server URL The new frontends are better for battery. Updates #2442 Updates tailscale/corp#2750 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	3b3994f0db	ipn{,/localapi,ipnlocal}: infer cert dir from state file location This fixes "tailscale cert" on Synology where the var directory is typically like /volume2/@appdata/Tailscale, or any other tailscaled user who specifies a non-standard state file location. This is a interim fix on the way to #2932. Fixes #2927 Updates #2932 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	aae622314e	tailcfg, health: add way for control plane to add problems to health check So if the control plane knows that something's broken about the node, it can include problem(s) in MapResponse and "tailscale status" will show it. (and GUIs in the future, as it's in ipnstate.Status/JSON) This also bumps the MapRequest.Version, though it's not strictly required. Doesn't hurt.

Josh Bleecher Snyder	07c09f470d	ipn/ipnlocal: do not shut down the backend halfway through TestStateMachine LocalBackend.Shutdown's docs say: > The backend can no longer be used after Shutdown returns. Nevertheless, TestStateMachine blithely calls Shutdown, talks some smack, and continues on, expecting things to work. Other uses of Shutdown in the codebase are as intended. Things mostly kinda work anyway, except that the wgengine.Engine has been shut down, so calls to Reconfig fail. Those get logged: > local.go:603: wgengine status error: engine closing; no status but otherwise ignored. However, the Reconfig failure caused one fewer call to pause/unpause than normal. Now the assertCalls lines match the equivalent ones earlier in the test. I don't see an obvious correct replacement for Shutdown in the context of this test; I'm not sure entirely what it is trying to accomplish. It is possible that many of the tests remaining after the prior call to Shutdown are now extraneous. They don't harm anything, though, so err on the side of safety and leave them for now.

Josh Bleecher Snyder	221cc5f8f2	ipn/ipnlocal: reduce line noise in tests Use helpers and variadic functions to make the call sites a lot easier to read, since they occur a lot. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Josh Bleecher Snyder	45d3174c0d	ipn/ipnlocal: add LocalBackend.broadcastStatusChanged To reduce repetition. Also, document why we acquire the lock. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Josh Bleecher Snyder	b7ede14396	Revert "ipn/ipnlocal: remove locks around sync.Cond.Broadcast call" Reason for revert: Causes ipnlocal tests to deadlock intermittently. This reverts commit `1b15349e01`. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Josh Bleecher Snyder	3ea8cf9c62	ipn/ipnlocal: use quicktest.IsNotNil in tests This didn't exist when the test was written. Now it does (frankban/quicktest#94); use it. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Josh Bleecher Snyder	1b15349e01	ipn/ipnlocal: remove locks around sync.Cond.Broadcast call They are unnecessary. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago

Josh Bleecher Snyder	b681edc572	ipn/ipnlocal: add failing test Concurrent calls to LocalBackend.setWgengineStatus could result in some of the status updates being dropped. This was exacerbated by `92077ae78c`, which increases the probability of concurrent status updates, causing test failures (tailscale/corp#2579). It's going to take a bit of work to fix this test. The ipnlocal state machine is difficult to reason about, particularly in the face of concurrency. We could fix the test trivially by throwing a new mutex around setWgengineStatus to serialize calls to it, but I'd like to at least try to do better than cosmetics. In the meantime, commit the test.

Josh Bleecher Snyder	7693d36aed	all: close fake userspace engines when tests complete We were leaking FDs. In a few places, switch from defer to t.Cleanup. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Brad Fitzpatrick	640134421e	all: update tests to use tstest.MemLogger And give MemLogger a mutex, as one caller had, which does match the logf contract better. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago

Brad Fitzpatrick	2bb0eb5f7e	ipn/ipnlocal: pull out dns.Config construction to its own func In prep for other bug fixes & tests. It's hard to test when it was intermingled into LocalBackend.authReconfig. Now it's a pure function. And rename variable 'uc' (user config?) to the since idiomatic 'prefs'.

David Crawshaw	9502b515f1	net/dns: replace resolver IPs with type for DoH We currently plumb full URLs for DNS resolvers from the control server down to the client. But when we pass the values into the net/dns package, we throw away any URL that isn't a bare IP. This commit continues the plumbing, and gets the URL all the way to the built in forwarder. (It stops before plumbing URLs into the OS configurations that can handle them.) For #2596 Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	3 years ago
Dave Anderson	980acc38ba	types/key: add a special key with custom serialization for control private keys (#2792 ) * Revert "Revert "types/key: add MachinePrivate and MachinePublic."" This reverts commit `61c3b98a24`. Signed-off-by: David Anderson <danderson@tailscale.com> * types/key: add ControlPrivate, with custom serialization. ControlPrivate is just a MachinePrivate that serializes differently in JSON, to be compatible with how the Tailscale control plane historically serialized its private key.

Josh Bleecher Snyder	a666b546fb	ipn/ipnlocal: log number of packet filters rather than entire filter The number of packet filters can grow very large, so this log entry can be very large.

Joe Tsai	9a0c8bdd20	util/deephash: make hash type opaque The fact that Hash returns a [sha256.Size]byte leaks details about the underlying hash implementation. This could very well be any other hashing algorithm with a possible different block size. Abstract this implementation detail away by declaring an opaque type that is comparable. While we are changing the signature of UpdateHash, rename it to just Update to reduce stutter (e.g., deephash.Update). Signed-off-by: Joe Tsai <joetsai@digital-static.net>	3 years ago
Brad Fitzpatrick	b6d70203d3	ipn/ipnlocal: fix 'tailscale up' on Windows without GUI With this, I can now: * install Tailscale * stop the GUI * net stop Tailscale * net start Tailscale * tailscale up --unattended (where the middle three steps simulate what would happen on a Windows Server Core machine without a GUI) Fixes #2137 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago

Brad Fitzpatrick	01e159b610	ipn/ipnlocal: save prefs to disk on UpdatePrefs Regression from `6d10655dc3`, which added UpdatePrefs but didn't write it out to disk. I'd planned on adding tests to state_test.go which is why I'd earlier added `46896a9311` to prepare for making such persistence tests easier to write, but turns out state_test.go didn't even test UpdatePrefs, so I'm staying out of there. Instead, this is tested using integration tests. Fixes #2321 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
