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. (See [this link](https://docs.microsoft.com/en-us/windows/win32/api/winsvc/nc-winsvc-lphandler_function_ex) for information re: handling `SERVICE_CONTROL_SESSIONCHANGE`.)

Brad Fitzpatrick	a7cb241db1	cmd/tailscaled: add support for running an HTTP proxy This adds support for tailscaled to be an HTTP proxy server. It shares the same backend dialing code as the SOCK5 server, but the client protocol is HTTP (including CONNECT), rather than SOCKS.

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

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.

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	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

Christine Dodrill	60f34c70a2	tstest/integration/vms: disable rDNS for sshd on centos (#2492 ) This prevents centos tests from timing out because sshd does reverse dns lookups on every session being established instead of doing it once on the acutal ssh connection being established. This is odd. Appending this to the sshd config and restarting it seems to fix it though. Signed-off-by: Christine Dodrill <xe@tailscale.com>	3 years ago

Josh Bleecher Snyder	0aa77ba80f	tstest/integration: fix filch test flake Filch doesn't like having multiple processes competing for the same log files (#937). Parallel integration tests were all using the same log files. Add a TS_LOGS_DIR env var that the integration test can use to use separate log files per test.

Josh Bleecher Snyder	f80193fa4c	tstest/integration: shorten test names The maximum unix domain socket path length on darwin is 104 bytes, including the trailing NUL. On my machine, the path created by some newly added tests (`6eecf3c9`) was too long, resulting in cryptic test failures. Shorten the names of the tests, and add a check to make the diagnosis easier next time. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	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
Josh Bleecher Snyder	4b1f2ae382	tstest/integration: generate deps for all platforms in deps generator We have different deps depending on the platform. If we pick a privileged platform, we'll miss some deps. If we use the union of all platforms, the integration test won't compile on some platforms, because it'll import packages that don't compile on that platform. Give in to the madness and give each platform its own deps file. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago

Christine Dodrill	798b0da470	tstest/integration/vms: codegen for top level tests (#2441 ) This moves the distribution definitions into a maintainable hujson file instead of just existing as constants in `distros.go`. Comments are maintained from the inline definitions. This uses jennifer[1] for hygenic source tree creation. This allows us to generate a unique top-level test for each VM run. This should hopefully help make the output of `go test` easier to read. This also separates each test out into its own top-level test so that we can better track the time that each distro takes. I really wish there was a way to have the `test_codegen.go` file _always_ run as a part of the compile process instead of having to rely on people remembering to run `go generate`, but I am limited by my tools. This will let us remove the `-distro-regex` flag and use `go test -run` to pick which distros are run. Signed-off-by: Christine Dodrill <xe@tailscale.com>	3 years ago

julianknodt	1bb6abc604	net/portmapper: add upnp port mapping Add in UPnP portmapping, using goupnp library in order to get the UPnP client and run the portmapping functions. This rips out anywhere where UPnP used to be in portmapping, and has a flow separate from PMP and PCP.

Christine Dodrill	3ebe16558c	tstest/integration/vms: attempt to send more UDP packets (#2433 ) Apparently this test was flaking because I critically misunderstood how the kernel buffers UDP packets for senders. I'm trying to send more UDP packets and will see if that helps. Signed-off-by: Christine Dodrill <xe@tailscale.com>	3 years ago
Christine Dodrill	09e81b8ba1	tstest/integration/vms: deflake the tailscale_status test (#2427 ) This test used to try to run this only once, but this variant of the test attempts to run `tailscale status` up to 6 times in a loop with exponential backoff. This fixes the flakiness found in previous instances of this test. Signed-off-by: Christine Dodrill <xe@tailscale.com>	3 years ago
