Brad Fitzpatrick	01b4bec33f	stunner: re-do how Stunner works ... It used to make assumptions based on having Anycast IPs that are super near. Now we're intentionally going to a bunch of different distant IPs to measure latency. Also, optimize how the hairpin detection works. No need to STUN on that socket. Just use that separate socket for sending, once we know the other UDP4 socket's endpoint. The trick is: make our test probe also a STUN packet, so it fits through magicsock's existing STUN routing. This drops netcheck from ~5 seconds to ~250-500ms. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago

David Anderson	7eda3af034	wgengine/magicsock: clean up derp http servers on shutdown. ... Failure to do this leads to fd exhaustion at -count=10000, and increasingly poor execution north of -count=100. Signed-off-by: David Anderson <danderson@tailscale.com>	5 years ago
David Anderson	d651715528	wgengine/magicsock: synchronize test STUN shutdown. ... Failure to do so triggers either a data race or a panic in the testing package, due to racey use of t.Logf. Signed-off-by: David Anderson <danderson@tailscale.com>	5 years ago

Brad Fitzpatrick	5c1e443d34	wgengine/monitor: don't call LinkChange when interfaces look unchanged ... Basically, don't trust the OS-level link monitor to only tell you interesting things. Sanity check it. Also, move the interfaces package into the net directory now that we have it.	5 years ago

David Crawshaw	0f73070a57	wgengine: shut down wireguard on Close ... This was (presumably) missing from wgengine because the interactions between magicsock and wireguard-go meant that the shutdown never worked. Now those are fixed, actually shut down. Fixes occasional flake in expanded ipn/e2e_test. Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	5 years ago

Martin Baillie	8ae3ba0cf5	wgengine: define default tunname for each platform ... The device name "tailscale0" will be used for all platforms except for OpenBSD where "tun" is enforced by the kernel. `CreateTUN()` in `wireguard-go` will select the next available "tunX" device name on the OpenBSD system.

David Anderson	f265603110	wgengine/magicsock: fix data race in ReceiveIPv4. ... The UDP reader goroutine was clobbering `n` and `err` from the main goroutine, whose accesses are not synchronized the way `b` is. Signed-off-by: David Anderson <danderson@tailscale.com>	5 years ago
David Anderson	77354d4617	wgengine/magicsock: unblock wireguard-go's read on magicsock shutdown. ... wireguard-go closes magicsock, and expects this to unblock reads so that its internal goroutines can wind down. We were incorrectly blocking the read indefinitey and breaking this contract. Signed-off-by: David Anderson <danderson@tailscale.com>	5 years ago

David Anderson	643bf14653	wgengine/magicsock: disable the new ping test. ... It's extremely flaky in several dimensions, as well as very slow. It's making the CI completely red all the time without telling us useful information. Set RUN_CURSED_TESTS=1 to run locally.	5 years ago

David Anderson	c8ebac2def	wgengine/magicsock: try deflaking again. ... This change just alters the semantics of the one flaky test, without trying to speed up timeouts on the others. Empirically, speeding up the timeouts causes _more_ flakes right now :(	5 years ago
David Anderson	cd1ac63b4c	Revert "wgengine/magicsock: temporarily deflake." ... This reverts commit c5835c6ced.	5 years ago
David Anderson	c5835c6ced	wgengine/magicsock: temporarily deflake. ... The remaining flake occurs due to a mysterious packet loss. This doesn't affect normal tailscaled operations, so until I track down where the loss occurs and fix it, the flaky test is going to be lenient about packet loss (but not about whether the spray logic worked).
