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>	4 years ago
David Anderson	77af7e5436	wgengine/magicsock: mark test logfunc as a helper. Signed-off-by: David Anderson <danderson@tailscale.com>	4 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>	4 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>	4 years ago
David Anderson	592fec7606	wgengine/magicsock: move device close to uncursed portion of test. Device close used to suffer from deadlocks, but no longer. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
Brad Fitzpatrick	39c0ae1dba	derp/derpmap: new DERP config package, merge netcheck into magicsock more Fixes #153 Updates #162 Updates #163 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago

David Anderson	bb93d7aaba	wgengine/magicsock: plumb logf throughout, and expose in Options. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	e3172ae267	wgengine/magicsock: uncurse TestDeviceStartStop, let CI run it. Signed-off-by: David Anderson <danderson@tailscale.com>	4 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>	4 years ago
David Anderson	fdee5fb639	wgengine/magicsock: don't mutexly reach inside Conn to tweak DERP settings. Signed-off-by: David Anderson <danderson@tailscale.com>	4 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.	4 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 :(	4 years ago
David Anderson	cd1ac63b4c	Revert "wgengine/magicsock: temporarily deflake." This reverts commit `c5835c6ced`.	4 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). Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	bd60a750e8	wgengine/magicsock: fix packet spraying test to (mostly) pass. It previously passed incorrectly due to bugs. With those fixed, it becomes flaky for 2 reasons. One of them is the wireguard handshake race, which can eat the 1st sprayed packet and prevent roamAddr discovery. This change fixes that failure, by spreading the test traffic out enough that additional spraying occurs. Signed-Off-By: David Anderson <danderson@tailscale.com>	4 years ago
