Tom DNetto	f1ab11e961	ipn/ipnlocal,tailcfg: introduce capability to gate TKA init paths Previously, `TAILSCALE_USE_WIP_CODE` was needed to hit a bunch of the TKA paths. With this change: - Enablement codepaths (NetworkLockInit) and initialization codepaths (tkaBootstrapFromGenesisLocked via tkaSyncIfNeeded) require either the WIP envknob or CapabilityTailnetLockAlpha. - Normal operation codepaths (tkaSyncIfNeeded, tkaFilterNetmapLocked) require TKA to be initialized, or either-or the envknob / capability. - Auxillary commands (ie: changing tka keys) require TKA to be initialized. The end result is that it shouldn't be possible to initialize TKA (or subsequently use any of its features) without being sent the capability or setting the envknob on tailscaled yourself. I've also pulled out a bunch of unnecessary checks for CanSupportNetworkLock(). Signed-off-by: Tom DNetto <tom@tailscale.com>	2 years ago

Denton Gentry	a200a23f97	Revert "cmd/tailscale: access QNAP via localhost" When running `tailscale web` as a standalone process, it was necessary to send auth requests to QTS using localhost to avoid hitting the proxy recursively. However running `tailscale web` as a process means it is consuming RAM all the time even when it isn't actively doing anything. After switching back to the `tailscale web` CGI mode, we don't need to specifically use localhost for QNAP auth. This reverts commit `e0cadc5496`.

Aaron Klotz	659e7837c6	health, ipn/ipnlocal: when -no-logs-no-support is enabled, deny access to tailnets that have network logging enabled We want users to have the freedom to start tailscaled with `-no-logs-no-support`, but that is obviously in direct conflict with tailnets that have network logging enabled. When we detect that condition, we record the issue in health, notify the client, set WantRunning=false, and bail. We clear the item in health when a profile switch occurs, since it is a per-tailnet condition that should not propagate across profiles. Signed-off-by: Aaron Klotz <aaron@tailscale.com>	2 years ago

Brad Fitzpatrick	06c4c47d46	ipn: remove unused Backend interface Only the macOS/iOS clients care about it still, so we'll move it to their repo.

Joe Tsai	2e5d08ec4f	net/connstats: invert network logging data flow (#6272 ) Previously, tstun.Wrapper and magicsock.Conn managed their own statistics data structure and relied on an external call to Extract to extract (and reset) the statistics. This makes it difficult to ensure a maximum size on the statistics as the caller has no introspection into whether the number of unique connections is getting too large. Invert the control flow such that a connstats.Statistics is registered with tstun.Wrapper and magicsock.Conn. Methods on non-nil connstats.Statistics are called for every packet. This allows the implementation of connstats.Statistics (in the future) to better control when it needs to flush to ensure bounds on maximum sizes. The value registered into tstun.Wrapper and magicsock.Conn could be an interface, but that has two performance detriments: 1. Method calls on interface values are more expensive since they must go through a virtual method dispatch. 2. The implementation would need a sync.Mutex to protect the statistics value instead of using an atomic.Pointer. Given that methods on constats.Statistics are called for every packet, we want reduce the CPU cost on this hot path. Signed-off-by: Joe Tsai <joetsai@digital-static.net>	2 years ago
Joe Tsai	35c10373b5	types/logid: move logtail ID types here (#6336 ) Many packages reference the logtail ID types, but unfortunately pull in the transitive dependencies of logtail.

Brad Fitzpatrick	3b0de97e07	cmd/tailscaled: unify the two Windows paths + separate IPN server path tailscaled on Windows had two entirely separate start-up paths for running as a service vs in the foreground. It's been causing problems for ages. This unifies the two paths, making them be the same as the path used for every other platform. Also, it uses the new async LocalBackend support in ipnserver.Server so the Server can start serving HTTP immediately, even if tun takes awhile to come up.

Brad Fitzpatrick	e8cc78b1af	ipn/ipnserver: change Server to let LocalBackend be supplied async This is step 1 of de-special-casing of Windows and letting the LocalAPI HTTP server start serving immediately, even while the rest of the world (notably the Engine and its TUN device) are being created, which can take a few to dozens of seconds on Windows. With this change, the ipnserver.New function changes to not take an Engine and to return immediately, not returning an error, and let its Run run immediately. If its ServeHTTP is called when it doesn't yet have a LocalBackend, it returns an error. A TODO in there shows where a future handler will serve status before an engine is available. Future changes will: * delete a bunch of tailscaled_windows.go code and use this new API * add the ipnserver.Server ServerHTTP handler to await the engine being available * use that handler in the Windows GUI client Updates #6522 Change-Id: Iae94e68c235e850b112a72ea24ad0e0959b568ee Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
