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	42a0e0c601	wgengine/magicsock/tests: call tstest.ResourceCheck for each test. This didn't catch anything yet, but it's good practice for detecting goroutine leaks that we might not find otherwise. 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

Dmytro Shynkevych	33b2f30cea	wgengine: wrap tun.Device to support filtering and packet injection (#358 ) Right now, filtering and packet injection in wgengine depend on a patch to wireguard-go that probably isn't suitable for upstreaming. This need not be the case: wireguard-go/tun.Device is an interface. For example, faketun.go implements it to mock a TUN device for testing. This patch implements the same interface to provide filtering and packet injection at the tunnel device level, at which point the wireguard-go patch should no longer be necessary. This patch has the following performance impact on i7-7500U @ 2.70GHz, tested in the following namespace configuration: ┌────────────────┐ ┌─────────────────────────────────┐ ┌────────────────┐ │ $ns1 │ │ $ns0 │ │ $ns2 │ │ client0 │ │ tailcontrol, logcatcher │ │ client1 │ │ ┌─────┐ │ │ ┌──────┐ ┌──────┐ │ │ ┌─────┐ │ │ │vethc│───────┼────┼──│vethrc│ │vethrs│──────┼─────┼──│veths│ │ │ ├─────┴─────┐ │ │ ├──────┴────┐ ├──────┴────┐ │ │ ├─────┴─────┐ │ │ │10.0.0.2/24│ │ │ │10.0.0.1/24│ │10.0.1.1/24│ │ │ │10.0.1.2/24│ │ │ └───────────┘ │ │ └───────────┘ └───────────┘ │ │ └───────────┘ │ └────────────────┘ └─────────────────────────────────┘ └────────────────┘ Before: --------------------------------------------------- \| TCP send \| UDP send \| \|------------------------\|------------------------\| \| 557.0 (±8.5) Mbits/sec \| 3.03 (±0.02) Gbits/sec \| --------------------------------------------------- After: --------------------------------------------------- \| TCP send \| UDP send \| \|------------------------\|------------------------\| \| 544.8 (±1.6) Mbits/sec \| 3.13 (±0.02) Gbits/sec \| --------------------------------------------------- The impact on receive performance is similar.

David Anderson	72cae5504c	wgengine: generate and plumb router.Settings in from ipn. This saves a layer of translation, and saves us having to pass in extra bits and pieces of the netmap and prefs to wgengine. Now it gets one Wireguard config, and one OS network stack config.

Wendi Yu	0c69b4e00d	Implement rate limiting on log messages (#356 ) Implement rate limiting on log messages Addresses issue #317, where logs can get spammed with the same message nonstop. Created a rate limiting closure on logging functions, which limits the number of messages being logged per second based on format string. To keep memory usage as constant as possible, the previous cache purging at periodic time intervals has been replaced by an LRU that discards the oldest string when the capacity of the cache is reached.

Brad Fitzpatrick	44b07aa708	netcheck: STUN less aggressively to known distant servers If Australia's far away and not going to be used, it's still going to be far away a minute later. No need to send backup just-in-case-UDP-gets-lost STUN packets to the known far away destinations. Those are the ones most likely to trigger retries due to delay anyway (in random 50-250ms, currently). But we'll keep sending 1 packet to them, just in case our airplane landed. Likewise, be less aggressive with IPv6. The main point is just to see whether IPv6 works. No need to send up to 10 packets every round. Max two is enough (except for the first round). This does mean our STUN traffic graphs for IPv4-vs-IPv6 will change shape. Oh well. It was a weird eyeball metric for IPv6 connectivity anyway and we have better metrics. We can tweak this policy over time. It's factored out and has tests now.	5 years ago
