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>	4 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.

David Anderson	efc1feedc9	wgengine/router: include more information when iptables ops fail.

Wendi Yu	fde384b359	Fix macOS build staticcheck used to fail on macOS (and presumably windows) due to a variable declared in a common package that was only used by the Linux build, which would prevent `redo pr` from passing on Mac.

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.	4 years ago
