Andrew Dunham	c6162c2a94	net/netcheck: add check for captive portal (#5593 ) This doesn't change any behaviour for now, other than maybe running a full netcheck more often. The intent is to start gathering data on captive portals, and additionally, seeing this in the 'tailscale netcheck' command should provide a bit of additional information to users.

Aaron Klotz	d915e0054c	cmd/tailscaled: change Windows service shutdown and add optional event logging Once a stop request is received and the service updates its status to `svc.StopPending`, it should continue running until the shutdown sequence is complete, and then return out of `(*ipnService).Execute`, which automatically sends a `svc.Stopped` notification to Windows. To make this happen, I changed the loop so that it runs until `doneCh` is closed, and then returns. I also removed a spurious `svc.StopPending` notification that the Windows Service Control Manager might be interpreting as a request for more time to shut down. Finally, I added some optional logging that sends a record of service notifications to the Windows event log, allowing us to more easily correlate with any Service Control Manager errors that are sent to the same log.

Josh Bleecher Snyder	4691e012a9	tstest/integration: build binaries only once The existing code relied on the Go build cache to avoid needless work when obtaining the tailscale binaries. For non-obvious reasons, the binaries were getting re-linked every time, which added 600ms or so on my machine to every test. Instead, build the binaries exactly once, on demand. This reduces the time to run 'go test -count=5' from 34s to 10s on my machine. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Josh Bleecher Snyder	63cd581c3f	safesocket: add ConnectionStrategy, provide control over fallbacks `fee2d9fad` added support for cmd/tailscale to connect to IPNExtension. It came in two parts: If no socket was provided, dial IPNExtension first, and also, if dialing the socket failed, fall back to IPNExtension. The second half of that support caused the integration tests to fail when run on a machine that was also running IPNExtension. The integration tests want to wait until the tailscaled instances that they spun up are listening. They do that by dialing the new instance. But when that dial failed, it was falling back to IPNExtension, so it appeared (incorrectly) that tailscaled was running. Hilarity predictably ensued. If a user (or a test) explicitly provides a socket to dial, it is a reasonable assumption that they have a specific tailscaled in mind and don't want to fall back to IPNExtension. It is certainly true of the integration tests. Instead of adding a bool to Connect, split out the notion of a connection strategy. For now, the implementation remains the same, but with the details hidden a bit. Later, we can improve that. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago

Brad Fitzpatrick	c37af58ea4	net/tsdial: move more weirdo dialing into new tsdial package, plumb Not done yet, but this move more of the outbound dial special casing from random packages into tsdial, which aspires to be the one unified place for all outbound dialing shenanigans. Then this plumbs it all around, so everybody is ultimately holding on to the same dialer. As of this commit, macOS/iOS using an exit node should be able to reach to the exit node's DoH DNS proxy over peerapi, doing the sockopt to stay within the Network Extension. A number of steps remain, including but limited to: * move a bunch more random dialing stuff * make netstack-mode tailscaled be able to use exit node's DNS proxy, teaching tsdial's resolver to use it when an exit node is in use.

Brad Fitzpatrick	d5405c66b7	net/tsdial: start of new package to unify all outbound dialing complexity For now this just deletes the net/socks5/tssocks implementation (and the DNSMap stuff from wgengine/netstack) and moves it into net/tsdial. Then initialize a Dialer early in tailscaled, currently only use for the outbound and SOCKS5 proxies. It will be plumbed more later. Notably, it needs to get down into the DNS forwarder for exit node DNS forwading in netstack mode. But it will also absorb all the peerapi setsockopt and netns Dial and tlsdial complexity too.

Josh Bleecher Snyder	4bb2c6980d	util/testingutil: new package with MinAllocsPerRun testing.AllocsPerRun measures the total allocations performed by the entire program while repeatedly executing a function f. If some unrelated part of the rest of the program happens to allocate a lot during that period, you end up with a test failure. Ideally, the rest of the program would be silent while testing.AllocsPerRun executes. Realistically, that is often unachievable. AllocsPerRun attempts to mitigate this by setting GOMAXPROCS to 1, but that doesn't prevent other code from running; it only makes it less likely. You can also mitigate this by passing a large iteration count to AllocsPerRun, but that is unreliable and needlessly expensive. Unlike most of package testing, AllocsPerRun doesn't use any toolchain magic, so we can just write a replacement. One wild idea is to change how we count mallocs. Instead of using runtime.MemStats, turn on memory profiling with a memprofilerate of 1. Discard all samples from the profile whose stack does not contain testing.AllocsPerRun. Count the remaining samples to determine the number of mallocs. That's fun, but overkill. Instead, this change adds a simple API that attempts to get f to run at least once with a target number of allocations. This is useful when you know that f should allocate consistently. We can then assume that any iterations with too many allocations are probably due to one-time costs or background noise. This suits most uses of AllocsPerRun. Ratcheting tests tend to be significantly less flaky, because they are biased towards success. They can also be faster, because they can exit early, once success has been reached.

Aaron Klotz	e016eaf410	cmd/tailscaled: conditionally flush Windows DNS cache on SessionChange For the service, all we need to do is handle the `svc.SessionChange` command. Upon receipt of a `windows.WTS_SESSION_UNLOCK` event, we fire off a goroutine to flush the DNS cache. (Windows expects responses to service requests to be quick, so we don't want to do that synchronously.) This is gated on an integral registry value named `FlushDNSOnSessionUnlock`, whose value we obtain during service initialization.

Brad Fitzpatrick	a353fbd3b4	tstest: make MemLogger.String acquire its mutex Updates #2781 (might even fix it, but its real issue is that SetPrivateKey starts a ReSTUN goroutines which then logs, and that bug and data race existed prior to MemLogger existing)	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	4c68b7df7c	tstest: add MemLogger bytes.Buffer wrapper with Logf method We use it tons of places. Updated three at least in this PR. Another use in next commit. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
David Crawshaw	b2a3d1da13	tstest/integration/vms: use fork of goexpect to avoid proto/grpc dep 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. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	61c3b98a24	Revert "types/key: add MachinePrivate and MachinePublic." Broke the tailscale control plane due to surprise different serialization. This reverts commit `4fdb88efe1`.	3 years ago
David Anderson	4fdb88efe1	types/key: add MachinePrivate and MachinePublic. Plumb throughout the codebase as a replacement for the mixed use of tailcfg.MachineKey and wgkey.Private/Public. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Crawshaw	4e18cca62e	testcontrol: replace panic with error I have seen this once in the VM test (caused by an EOF, I believe on shutdown) that didn't need to cause the test to fail. Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	3 years ago
David Crawshaw	f53792026e	tstest/integration/vms: move build tags from linux to !windows The tests build fine on other Unix's, they just can't run there. But there is already a t.Skip by default, so `go test` ends up working fine elsewhere and checks the code compiles. Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	3 years ago
Christine Dodrill	0b9e938152	tstest/integration/vms: test DNS configuration This uses a neat little tool to dump the output of DNS queries to standard out. This is the first end-to-end test of DNS that runs against actual linux systems. The /etc/resolv.conf test may look superflous, however this will help for correlating system state if one of the DNS tests fails. Signed-off-by: Christine Dodrill <xe@tailscale.com>	3 years ago
David Crawshaw	9b7fc2ed1f	.github: add Ubuntu VM test Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	3 years ago
David Crawshaw	debaaebf3b	tstest/integration/vms: turn on logcatcher logging by default Absolutely vital to debugging failures. Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	3 years ago
David Crawshaw	a1f1020042	tstest/integration/vms: avoid log after test completion Avoids a panic in the Go testing package if a late log comes in. Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	3 years ago
David Crawshaw	583af7c1a6	tstest/integration/vms: give guest multiple cores and use generic machine Speeds up tests. Allows the use of more version of qemu. Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	3 years ago
David Crawshaw	8668103f06	tstest/integration/vms: print qemu console output, fix printing issues Fix a few test printing issues when tests fail. Qemu console output is super useful when something is wrong in the harness and we cannot even bring up the tests. Also useful for figuring out where all the time goes in tests. A little noisy, but not too noisy as long as you're only running one VM as part of the tests, which is my plan. Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	3 years ago
David Crawshaw	1a9fba5b04	tstest/integration/vms: fix ubuntu URLs Also remove extra distros for now. We can bring them back later if useful. Though our most important distros are these two Ubuntu, debian stable, and Raspbian (not currently supported). And before doing more Linux, we should do Windows. Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	3 years ago
David Crawshaw	bb47feca44	tstest/integration: prefix logs with logid The VM test has two tailscaled instances running and interleaves the logs. Without a prefix it is impossible to figure out what is going on. It might be even better to include the [ABCD] node prefix here as well. Unfortunately lots of interesting logs happen before tailscaled has a node key, so it wouldn't be a replacement for a short ID. Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	3 years ago
Maisem Ali	fd4838dc57	wgengine/userspace: add support to automatically enable/disable the tailscale protocol in BIRD, when the node is a primary subnet router as determined by control. Signed-off-by: Maisem Ali <maisem@tailscale.com>	3 years ago
David Crawshaw	0b962567fa	vms: make ssh-keygen quiet by default Always succeeds. Its output clutters the log. Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	3 years ago
David Crawshaw	4fcce70df5	tstest/integration: listen on the specified IP By default httptest listens only on the loopback adapter. Instead, listen on the IP the user asked for. The VM test needs this, as it wants to start DERP and STUN servers on the host that can be reached by guest VMs. Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	3 years ago
David Crawshaw	0b2761ca92	testcontrol: plumb through DERP Without this tailscaled does not know the DERP of a peer. Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	3 years ago
slowy07	ac0353e982	fix: typo spelling grammar Signed-off-by: slowy07 <slowy.arfy@gmail.com>	3 years ago
Josh Bleecher Snyder	4ff0757d44	cmd/testcontrol: add test control server This is useful for manual performance testing of networks with many nodes. I imagine it'll grow more knobs over time. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
