James Tucker	43819309e1	.github/workflows: split tests and benchmarks for caching ... Benchmark flags prevent test caching, so benchmarks are now executed independently of tests. Fixes #7975 Signed-off-by: James Tucker <james@tailscale.com>	2 years ago
Maisem Ali	1b8a0dfe5e	ssh/tailssh: also handle recording upload failure during writes ... Previously we would error out when the recording server disappeared after the in memory buffer filled up for the io.Copy. This makes it so that we handle failing open correctly in that path.

Brad Fitzpatrick	90ba26cea1	net/netcheck: fix crash when IPv6 kinda but not really works ... Looks like on some systems there's an IPv6 address, but then opening a IPv6 UDP socket fails later. Probably some firewall. Tolerate it better and don't crash. To repro: check the "udp6" to something like "udp7" (something that'll fail) and run "go run ./cmd/tailscale netcheck" on a machine with active IPv6. It used to crash and now it doesn't. Fixes #7949 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Maisem Ali	7778d708a6	ssh/tailssh: handle dialing multiple recorders and failing open ... This adds support to try dialing out to multiple recorders each with a 5s timeout and an overall 30s timeout. It also starts respecting the actions `OnRecordingFailure` field if set, if it is not set it fails open. Updates tailscale/corp#9967 Signed-off-by: Maisem Ali <maisem@tailscale.com>	2 years ago
Maisem Ali	f66ddb544c	tailcfg: add SSHRecorderFailureAction and SSHRecordingFailureNotifyRequest ... This allows control to specify how to handle situations where the recorder isn't available. Updates tailscale/corp#9967 Signed-off-by: Maisem Ali <maisem@tailscale.com>	2 years ago

Mihai Parparita	7330aa593e	all: avoid repeated default interface lookups ... On some platforms (notably macOS and iOS) we look up the default interface to bind outgoing connections to. This is both duplicated work and results in logspam when the default interface is not available (i.e. when a phone has no connectivity, we log an error and thus cause more things that we will try to upload and fail). Fixed by passing around a netmon.Monitor to more places, so that we can use its cached interface state. Fixes #7850 Updates #7621 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Will Norris	7f17e04a5a	log/sockstatlog: bump logInterval to 10 seconds ... We are seeing indications that some devices are still getting into an upload loop. Bump logInterval in case these devices are on slow connections that are taking more than 3 seconds to uploads sockstats. Updates #7719 Signed-off-by: Will Norris <will@tailscale.com>	2 years ago
Mihai Parparita	4722f7e322	all: move network monitoring from wgengine/monitor to net/netmon ... We're using it in more and more places, and it's not really specific to our use of Wireguard (and does more just link/interface monitoring). Also removes the separate interface we had for it in sockstats -- it's a small enough package (we already pull in all of its dependencies via other paths) that it's not worth the extra complexity.

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. Updates #7876 Signed-off-by: James Tucker <jftucker@gmail.com>	2 years ago
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). Updates tailscale/corp#9230 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
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. 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

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.
