Josh Bleecher Snyder	e8cd7bb66f	tstest: simplify goroutine leak tests Use tb.Cleanup to simplify both the API and the implementation. One behavior change: When the number of goroutines shrinks, don't log. I've never found these logs to be useful, and they frequently add noise. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
Josh Bleecher Snyder	18471a8792	ipn: close logger at the end of TestLocalLogLines If any goroutine continues to use the logger in TestLocalLogLines after the test finishes, the test panics. The culprit for this was wireguard-go; the previous commit fixed that. This commit adds suspenders: When the test is done, make logging calls into no-ops.

David Anderson	f794493b4f	wgengine/magicsock: explicitly check path discovery, add a firewall test. The test proves that active discovery can traverse two facing firewalls. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	5a370d545a	tstest/natlab: drop packets that can't be routed in a LAN. LANs are authoritative for their prefixes, so we should not bounce packets back and forth to the default gateway in that case. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	45578b47f3	tstest/natlab: refactor PacketHandler into a larger interface. The new interface lets implementors more precisely distinguish local traffic from forwarded traffic, and applies different forwarding logic within Machines for each type. This allows Machines to be packet forwarders, which didn't quite work with the implementation of Inject. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	23123907c0	tstest/natlab: add a configurable SNAT44 translator. This lets us implement the most common kinds of NAT in the wild. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago

David Anderson	88e8456e9b	wgengine/magicsock: add a connectivity test for facing firewalls. The test demonstrates that magicsock can traverse two stateful firewalls facing each other, that each require localhost to initiate connections. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	b3d65ba943	tstest/natlab: refactor, expose a Packet type. HandlePacket and Inject now receive/take Packets. This is a handy container for the packet, and the attached Trace method can be used to print traces from custom packet handlers that integrate nicely with natlab's internal traces. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	5eedbcedd1	tstest/natlab: add a stateful firewall. The firewall provides a ProcessPacket handler, and implements an address-and-port endpoint dependent firewall that allows all traffic to egress from the trusted interface, and only allows inbound traffic if corresponding outbound traffic was previously seen. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	0ed9f62ed0	tstest/natlab: provide inbound interface to HandlePacket. Requires a bunch of refactoring so that Networks only ever refer to Interfaces that have been attached to them, and Interfaces know about both their Network and Machine.

Brad Fitzpatrick	7883e5c5e7	go.mod: restore staticcheck module, make it stick around, go mod tidy It kept coming & going as different people ran go mod tidy and others ran staticcheck. Make it stop going away with go mod tidy by adding a dep to it.	4 years ago

Avery Pennarun	4f128745d8	magicsock/test: oops, fix a data race in nested-test logf hack. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	5 years ago
Avery Pennarun	08acb502e5	Add tstest.PanicOnLog(), and fix various problems detected by this. If a test calls log.Printf, 'go test' horrifyingly rearranges the output to no longer be in chronological order, which makes debugging virtually impossible. Let's stop that from happening by making log.Printf panic if called from any module, no matter how deep, during tests. This required us to change the default error handler in at least one http.Server, as well as plumbing a bunch of logf functions around, especially in magicsock and wgengine, but also in logtail and backoff. To add insult to injury, 'go test' also rearranges the output when a parent test has multiple sub-tests (all the sub-test's t.Logf is always printed after all the parent tests t.Logf), so we need to screw around with a special Logf that can point at the "current" t (current_t.Logf) in some places. Probably our entire way of using subtests is wrong, since 'go test' would probably like to run them all in parallel if you called t.Parallel(), but it definitely can't because the're all manipulating the shared state created by the parent test. They should probably all be separate toplevel tests instead, with common setup/teardown logic. But that's a job for another time. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	5 years ago
Avery Pennarun	e0b666c5d2	tstest.ResourceCheck: clarify success message. Inclusion of the word "assert" made it seem like a failure, even though it was supposed to be identifying the name of the function (Assert()). Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	5 years ago
