Mihai Parparita	c7cea825ae	net/netns: don't log errors when we can't get the default route on Darwin ... It's somewhat common (e.g. when a phone has no reception), and leads to lots of logspam. Updates #7850 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Andrew Dunham	280255acae	various: add golangci-lint, fix issues (#7905) ... This adds an initial and intentionally minimal configuration for golang-ci, fixes the issues reported, and adds a GitHub Action to check new pull requests against this linter configuration.

Joe Tsai	ff1b35ec6c	net/connstats: exclude traffic with internal Tailscale service (#7904) ... Exclude traffic with 100.100.100.100 (for IPv4) and with fd7a:115c:a1e0::53 (for IPv6) since this traffic with the Tailscale service running locally on the node. This traffic never left the node. It also happens to be a high volume amount of traffic since DNS requests occur over UDP with each request coming from a unique port, thus resulting in many discrete traffic flows.

Brad Fitzpatrick	d5a870b4dc	wgengine/monitor: add --monitor-duration flag to opt-in TestMonitorMode ... TestMonitorMode skips by default, without the --monitor flag, and then it previously ran forever. This adds an option --monitor-duration flag that defaults to zero (run forever) but if non-zero bounds how long the tests runs. This means you can then also use e.g. `go test --cpuprofile` and capture a CPU/mem profile for a minute or two. Updates #7621 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Brad Fitzpatrick	162488a775	net/interfaces: cache "home" router lookup on big Linux routers ...

Andrew Dunham	80b138f0df	wgengine/magicsock: keep advertising endpoints after we stop discovering them ... Previously, when updating endpoints we would immediately stop advertising any endpoint that wasn't discovered during determineEndpoints. This could result in, for example, a case where we performed an incremental netcheck, didn't get any of our three STUN packets back, and then dropped our STUN endpoint from the set of advertised endpoints... which would result in clients falling back to a DERP connection until the next call to determineEndpoints. Instead, let's cache endpoints that we've discovered and continue reporting them to clients until a timeout expires. In the above case where we temporarily don't have a discovered STUN endpoint, we would continue reporting the old value, then re-discover the STUN endpoint again and continue reporting it as normal, so clients never see a withdrawal.

James Tucker	b7f51a1468	.github/workflows: add artifact caching and remove double build on race ... Go artifact caching will help provided that the cache remains small enough - we can reuse the strategy from the Windows build where we only cache and pull the zips, but let go(1) do the many-file unpacking as it does so faster. The race matrix was building once without race, then running all the tests with race, so change the matrix to incldue a `buildflags` parameter and use that both in the build and test steps.

David Anderson	a5fd51ebdc	net/art: disable the IPv6 100k routes benchmark. ... At the current unoptimized memory utilization of the various data structures, 100k IPv6 routes consumes in the ballpark of 3-4GiB, which risks OOMing our 386 test machine.

Mihai Parparita	edb02b63f8	net/sockstats: pass in logger to sockstats.WithSockStats ... Using log.Printf may end up being printed out to the console, which is not desirable. I noticed this when I was investigating some client logs with `sockstats: trace "NetcheckClient" was overwritten by another`. That turns to be harmless/expected (the netcheck client will fall back to the DERP client in some cases, which does its own sockstats trace). However, the log output could be visible to users if running the `tailscale netcheck` CLI command, which would be needlessly confusing.

Anton Tolchanov	8546ff98fb	tsweb: move varz handler(s) into separate modules ... This splits Prometheus metric handlers exposed by tsweb into two modules: - `varz.Handler` exposes Prometheus metrics generated by our expvar converter; - `promvarz.Handler` combines our expvar-converted metrics and native Prometheus metrics. By default, tsweb will use the promvarz handler, however users can keep using only the expvar converter. Specifically, `tailscaled` now uses `varz.Handler` explicitly, which avoids a dependency on the (heavyweight) Prometheus client.
