Brad Fitzpatrick	e18c3a7d84	wgengine: optimize isLocalAddr a bit On macOS/iOS, this removes a map lookup per outgoing packet. Noticed it while reading code, not from profiles, but can't hurt.

Josh Bleecher Snyder	0807e3e2f7	syncs: disable TestWatchMultipleValues on Windows CI builds The Windows CI machine experiences significant random execution delays. For example, in this code from watchdog.go: done := make(chan bool) go func() { start := time.Now() mu.Lock() There was a 500ms delay from initializing done to locking mu. This test checks that we receive a sufficient number of events quickly enough. In the face of random 500ms delays, unsurprisingly, the test fails. There's not much principled we can do about it. We could build a system of retries or attempt to detect these random delays, but that game isn't worth the candle. Skip the test. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
Josh Bleecher Snyder	4954fbfda6	wgengine: extend TestWatchdog timeout on macOS This works around the close syscall being slow. We can revert this if we find a fix or if Apple makes close fast again. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago

David Anderson	25e0bb0a4e	net/tstun: rename wrap_windows.go to tun_windows.go. The code has nothing to do with wrapping, it's windows-specific driver initialization code. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago

Brad Fitzpatrick	1642dfdb07	ipn/ipnlocal: get peerapi ~working in macOS/iOS NetworkExtension sandbox IPv4 and IPv6 both work remotely, but IPv6 doesn't yet work from the machine itself due to routing mysteries. Untested yet on iOS, but previous prototype worked on iOS, so should work the same. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago

Brad Fitzpatrick	7f174e84e6	net/interfaces: remove mutating methods, add EqualFiltered instead Now callers (wgengine/monitor) don't need to mutate the state to remove boring interfaces before calling State.Equal. Instead, the methods to remove boring interfaces from the State are removed, as is the reflect-using Equal method itself, and in their place is a new EqualFiltered method that takes a func predicate to match interfaces to compare. And then the FilterInteresting predicate is added for use with EqualFiltered to do the job that that wgengine/monitor previously wanted. Now wgengine/monitor can keep the full interface state around, including the "boring" interfaces, which we'll need for peerapi on macOS/iOS to bind to the interface index of the utunN device.

Brad Fitzpatrick	7dc88e4c1e	net/interfaces: track more interface metadata in State We have it already but threw it away. But macOS/iOS code will be needing the interface index, so hang on to it. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Adrian Dewhurst	04dd6d1dae	control/controlclient: sign RegisterRequest (#1549 ) control/controlclient: sign RegisterRequest Some customers wish to verify eligibility for devices to join their tailnets using machine identity certificates. TLS client certs could potentially fulfill this role but the initial customer for this feature has technical requirements that prevent their use. Instead, the certificate is loaded from the Windows local machine certificate store and uses its RSA public key to sign the RegisterRequest message. There is room to improve the flexibility of this feature in future and it is currently only tested on Windows (although Darwin theoretically works too), but this offers a reasonable starting place for now.
