Brad Fitzpatrick	ca65c6cbdb	cmd/tailscale: make 'file cp' have better error messages on bad targets Say when target isn't owned by current user, and when target doesn't exist in netmap. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Josh Bleecher Snyder	96ef8d34ef	ipn/ipnlocal: switch from testify to quicktest Per discussion, we want to have only one test assertion library, and we want to start by exploring quicktest. This was a mostly mechanical translation. I think we could make this nicer by defining a few helper closures at the beginning of the test. Later.

Brad Fitzpatrick	90002be6c0	cmd/tailscale: make pref-revert checks ignore OS-irrelevant prefs This fixes #1833 in two ways: * stop setting NoSNAT on non-Linux. It only matters on Linux and the flag is hidden on non-Linux, but the code was still setting it. Because of that, the new pref-reverting safety checks were failing when it was changing. * Ignore the two Linux-only prefs changing on non-Linux.

Avery Pennarun	6caa02428e	cmd/tailscale/cli/up: "LoggedOut" pref is implicit. There's no need to warn that it was not provided on the command line after doing a sequence of up; logout; up --args. If you're asking for tailscale to be up, you always mean that you prefer LoggedOut to become false. Fixes #1828 Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	4 years ago
Josh Bleecher Snyder	59026a291d	wgengine/wglog: improve wireguard-go logging rate limiting Prior to wireguard-go using printf-style logging, all wireguard-go logging occurred using format string "%s". We fixed that but continued to use %s when we rewrote peer identifiers into Tailscale style. This commit removes that %sl, which makes rate limiting work correctly. As a happy side-benefit, it should generate less garbage. Instead of replacing all wireguard-go peer identifiers that might occur anywhere in a fully formatted log string, assume that they only come from args. Check all args for things that look like *device.Peers and replace them with appropriately reformatted strings. There is a variety of ways that this could go wrong (unusual format verbs or modifiers, peer identifiers occurring as part of a larger printed object, future API changes), but none of them occur now, are likely to be added, or would be hard to work around if they did.

Josh Bleecher Snyder	1f94d43b50	wgengine/wglog: delay formatting The "stop phrases" we use all occur in wireguard-go in the format string. We can avoid doing a bunch of fmt.Sprintf work when they appear. Signed-off-by: Josh Bleecher Snyder <josharian@gmail.com>	4 years ago
Brad Fitzpatrick	544d8d0ab8	ipn/ipnlocal: remove NewLocalBackendWithClientGen This removes the NewLocalBackendWithClientGen constructor added in `b4d04a065f` and instead adds LocalBackend.SetControlClientGetterForTesting, mirroring LocalBackend.SetHTTPTestClient. NewLocalBackendWithClientGen was weird in being exported but taking an unexported type. This was noted during code review: https://github.com/tailscale/tailscale/pull/1818#discussion_r623155669 which ended in: "I'll leave it for y'all to clean up if you find some way to do it elegantly." This is more idiomatic. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Avery Pennarun	0181a4d0ac	ipnlocal: don't pause the controlclient until we get at least one netmap. Without this, macOS would fail to display its menu state correctly if you started it while !WantRunning. It relies on the netmap in order to show the logged-in username. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	4 years ago
Avery Pennarun	4ef207833b	ipn: !WantRunning + !LoggedOut should not be idle on startup. There was logic that would make a "down" tailscale backend (ie. !WantRunning) refuse to do any network activity. Unfortunately, this makes the macOS and iOS UI unable to render correctly if they start while !WantRunning. Now that we have Prefs.LoggedOut, use that instead. So `tailscale down` will still allow the controlclient to connect its authroutine, but pause the maproutine. `tailscale logout` will entirely stop all activity. This new behaviour is not obviously correct; it's a bit annoying that `tailsale down` doesn't terminate all activity like you might expect. Maybe we should redesign the UI code to render differently when disconnected, and then revert this change. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	4 years ago
Avery Pennarun	4f3315f3da	ipnlocal: setting WantRunning with EditPrefs was special. EditPrefs should be just a wrapper around the action of changing prefs, but someone had added a side effect of calling Login() sometimes. The side effect happened after running the state machine, which would sometimes result in us going into NeedsLogin immediately before calling cc.Login(). This manifested as the macOS app not being able to Connect if you launched it with LoggedOut=false and WantRunning=false. Trying to Connect() would sent us to the NeedsLogin state instead.

Avery Pennarun	19c3e6cc9e	types/logger: rate limited: more hysteresis, better messages. - Switch to our own simpler token bucket, since x/time/rate is missing necessary stuff (can't provide your own time func; can't check the current bucket contents) and it's overkill anyway. - Add tests that actually include advancing time. - Don't remove the rate limit on a message until there's enough room to print at least two more of them. When we do, we'll also print how many we dropped, as a contextual reminder that some were previously lost. (This is more like how the Linux kernel does it.) - Reformat the [RATE LIMITED] messages to be shorter, and to not corrupt original message. Instead, we print the message, then print its format string. - Use %q instead of \"%s\", for more accurate parsing later, if the format string contained quotes.

Avery Pennarun	b7e31ab1a4	ipn: mock controlclient.Client; big ipn.Backend state machine test. A very long unit test that verifies the way the controlclient and ipn.Backend interact. This is a giant sequential test of the state machine. The test passes, but only because it's asserting all the wrong behaviour. I marked all the behaviour I think is wrong with BUG comments, and several additional test opportunities with TODO. Note: the new test supercedes TestStartsInNeedsLoginState, which was checking for incorrect behaviour (although the new test still checks for the same incorrect behaviour) and assumed .Start() would converge before returning, which it happens to do, but only for this very specific case, for the current implementation. You're supposed to wait for the notifications. Updates: tailscale/corp#1660 Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	4 years ago

Josh Bleecher Snyder	7ee891f5fd	all: delete wgcfg.Key and wgcfg.PrivateKey For historical reasons, we ended up with two near-duplicate copies of curve25519 key types, one in the wireguard-go module (wgcfg) and one in the tailscale module (types/wgkey).

Josh Bleecher Snyder	9d542e08e2	wgengine/magicsock: always run ReceiveIPv6 One of the consequences of the bind refactoring in `6f23087175` is that attempting to bind an IPv6 socket will always result in c.pconn6.pconn being non-nil. If the bind fails, it'll be set to a placeholder packet conn that blocks forever. As a result, we can always run ReceiveIPv6 and health check it. This removes IPv4/IPv6 asymmetry and also will allow health checks to detect any IPv6 receive func failures. Signed-off-by: Josh Bleecher Snyder <josharian@gmail.com>	4 years ago

Josh Bleecher Snyder	3c543c103a	wgengine/magicsock: unify initial bind and rebind We had two separate code paths for the initial UDP listener bind and any subsequent rebinds. IPv6 got left out of the rebind code. Rather than duplicate it there, unify the two code paths. Then improve the resulting code: * Rebind had nested listen attempts to try the user-specified port first, and then fall back to :0 if that failed. Convert that into a loop. * Initial bind tried only the user-specified port. Rebind tried the user-specified port and 0. But there are actually three ports of interest: The one the user specified, the most recent port in use, and 0. We now try all three in order, as appropriate. * In the extremely rare case in which binding to port 0 fails, use a dummy net.PacketConn whose reads block until close. This will keep the wireguard-go receive func goroutine alive. As a pleasant side-effect of this, if we decide that we need to resuscitate #1796, it will now be much easier.
