Andrew Dunham	3ede3aafe4	ipn/localapi: also verify STUN queries work in 'debug derp' ... Updates #6526 Signed-off-by: Andrew Dunham <andrew@du.nham.ca> Change-Id: I274b7ed53ee0be3fb94fdb00cafe06a1d676e1cf	2 years ago
James Tucker	f844791e15	safesocket: enable test to run on Windows unpriviliged ... I manually tested that the code path that relaxes pipe permissions is not executed when run with elevated priviliges, and the test also passes in that case.

James Tucker	cd35a79136	syncs: relax TestWatchMultipleValues timing on Windows ... The test is re-enabled for Windows with a relaxed time assertion. On Windows the runtime poller currently does not have sufficient resolution to meet the normal requirements for this test. See https://github.com/golang/go/issues/44343 for background.

Andrew Dunham	f85dc6f97c	ci: add more lints (#7909) ... This is a follow-up to #7905 that adds two more linters and fixes the corresponding findings. As per the previous PR, this only flags things that are "obviously" wrong, and fixes the issues found.

Maisem Ali	c3ef6fb4ee	ipn/ipnlocal: handle masquerade addresses in PeerAPI ... Without this, the peer fails to do anything over the PeerAPI if it has a masquerade address. ``` Apr 19 13:58:15 hydrogen tailscaled[6696]: peerapi: invalid request from <ip>:58334: 100.64.0.1/32 not found in self addresses ``` Updates #8020 Signed-off-by: Maisem Ali <maisem@tailscale.com>	2 years ago
Maisem Ali	85de580455	net/tsdial: do not use proxies when dialing out to PeerAPI ... Found this when adding a test that does a ping over PeerAPI. Our integration tests set up a trafficTrap to ensure that tailscaled does not call out to the internet, and it does so via a HTTP_PROXY. When adding a test for pings over PeerAPI, it triggered the trap and investigation lead to the realization that we were not removing the Proxy when trying to dial out to the PeerAPI.

Mihai Parparita	d0906cda97	net/sockstats: expose debug info ... Exposes some internal state of the sockstats package via the C2N and PeerAPI endpoints, so that it can be used for debugging. For now this includes the estimated radio on percentage and a second-by-second view of the times the radio was active. Also fixes another off-by-one error in the radio on percentage that was leading to >100% values (if n seconds have passed since we started to monitor, there may be n + 1 possible seconds where the radio could have been on).

Will Norris	7c386ca6d2	net/sockstats: fix calculation of radio power usage ... When splitting the radio monitor usage array, we were splitting at now % 3600 to get values into chronological order. This caused the value for the final second to be included at the beginning of the ordered slice rather than the end. If there was activity during that final second, an extra five seconds of high power usage would get recorded in some cases. This could result in a final calculation of greater than 100% usage. This corrects that by splitting values at (now+1 % 3600). This also simplifies the percentage calculation by always rounding values down, which is sufficient for our usage.

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.

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

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.

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.

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.

Specifically, `tailscaled` now uses `varz.Handler` explicitly, which avoids a dependency on the (heavyweight) Prometheus client.

Anton Tolchanov	c153e6ae2f	prober: migrate to Prometheus metric library ... This provides an example of using native Prometheus metrics with tsweb. Prober library seems to be the only user of PrometheusVar, so I am removing support for it in tsweb.

Anton Tolchanov	11e6247d2a	tsweb: expose native Prometheus metrics in /debug/varz ... The handler will expose built-in process and Go metrics by default, which currently duplicate some of the expvar-proxied metrics (`goroutines` vs `go_goroutines`, `memstats` vs `go_memstats`), but as long as their names are different, Prometheus server will just scrape both. This will change /debug/varz behaviour for most tsweb binaries, but notably not for control, which configures a `tsweb.VarzHandler` [explicitly](a5b5d5167f/cmd/tailcontrol/tailcontrol.go (L779)) Updates https://github.com/tailscale/corp/issues/10205 Signed-off-by: Anton Tolchanov <anton@tailscale.com>	2 years ago

Mihai Parparita	cef0a474f8	ipn/ipnlocal: check that sockstatLogger is available in c2n endpoint ... Otherwise there may be a panic if it's nil (and the control side of the c2n call will just time out). Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
