Brad Fitzpatrick	b0f8931d26	wgengine/magicsock: make a test signature a bit more explicit	5 years ago
David Crawshaw	7ec54e0064	wgengine/magicsock: remove TODO ... The TODO above derphttp.NewClient suggests it does network I/O, but the derphttp client connects lazily and so creating one is very cheap. Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	5 years ago
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 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.

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). Signed-off-by: David Anderson <danderson@tailscale.com>	5 years ago
Brad Fitzpatrick	61d83f759b	wgengine/magicsock: remove redundant derpMagicIP comparison ... Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 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>	5 years ago
David Anderson	ef31dd7bb5	wgengine/magicsock: check all 3 fast paths independently. ... The previous code would skip the DERP short-circuit if roamAddr was set, which is not what we wanted. More generally, hitting any of the fast path conditions is a direct return, so we can just have 3 standalone branches rather than 'else if' stuff. Signed-Off-By: David Anderson <danderson@tailscale.com>	5 years ago
David Anderson	05a52746a4	wgengine/magicsock: fix destination selection logic to work with DERP. ... The effect is subtle: when we're not spraying packets, and have not yet figured out a curAddr, and we're not spraying, we end up sending to whatever the first IP is in the iteration order. In English, that means "when we have no idea where to send packets, and we've given up on sending to everyone, just send to the first addr we see in the list." This is, in general, what we want, because the addrs are in sorted preference order, low to high, and DERP is the least preferred destination. So, when we have no idea where to send, send to DERP, right? ... Except for very historical reasons, appendDests iterated through addresses in _reverse_ order, most preferred to least preferred. crawshaw@ believes this was part of the earliest handshaking algorithm magicsock had, where it slowly iterated through possible destinations and poked handshakes to them one at a time. Anyway, because of this historical reverse iteration, in the case described above of "we have no idea where to send", the code would end up sending to the _most_ preferred candidate address, rather than the _least_ preferred. So when in doubt, we'd end up firing packets into the blackhole of some LAN address that doesn't work, and connectivity would not work. This case only comes up if all your non-DERP connectivity options have failed, so we more or less failed to detect it because we didn't have a pathological test box deployed. Worse, codependent bug 2839854994 made DERP accidentally work sometimes anyway by incorrectly exploiting roamAddr behavior, albeit at the cost of making DERP traffic symmetric. In fixing DERP to once again be asymmetric, we effectively removed the bandaid that was concealing this bug. Signed-Off-By: David Anderson <danderson@tailscale.com>	5 years ago

Brad Fitzpatrick	fe0051fafd	wgengine/magicsock: expand AddrSet.addrs comment	5 years ago
David Anderson	2839854994	wgengine/magicsock: never set a DERP server as a roamAddr. ... DERP traffic is asymmetric by design, with nodes always sending to their peer's home DERP server. However, if roamAddr is set, magicsock will always push data there, rather than let DERP server selection do its thing, so we end up accidentally creating a symmetric flow.

Brad Fitzpatrick	2cff9016e4	net/dnscache: add overly simplistic DNS cache package for selective use ... I started to write a full DNS caching resolver and I realized it was overkill and wouldn't work on Windows even in Go 1.14 yet, so I'm doing this tiny one instead for now, just for all our netcheck STUN derp lookups, and connections to DERP servers. (This will be caching a exactly 8 DNS entries, all ours.) Fixes #145 (can be better later, of course)	5 years ago

David Crawshaw	c576a57067	wgengine: avoid holding any locks during HandshakeDone ... Because wgLock is held while some wireguard-go methods run, trying to hold wgLock during HandshakeDone potentially creates lock cycles between wgengine and internals of wireguard-go. Arguably wireguard-go should call HandshakeDone in a new goroutine, but until its API promises that, don't make any assumptions here. Maybe for #110.

David Crawshaw	7a3be96199	wgengine: add pinger to generate initial spray packets ... For 3 seconds after a successful handshake, wgengine will send a ping packet every 300ms to its peer. This ensures the spray logic in magicsock has something to spray. Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	5 years ago
David Crawshaw	a6ad3c46e2	magicsock: spray some normal packets after a handshake ... In particular, this is designed to catch the case where a HandshakeInitiation packet is sent out but the intermediate NATs have not been primed, so the packet passes over DERP. In that case, the HandshakeResponse also comes back over DERP, and the connection proceeds via DERP without ever trying to punch through the NAT. With this change, the HandshakeResponse (which was sprayed out and so primed one NAT) triggers an UpdateDst, which triggers the extra spray logic. (For this to work, there has to be an initial supply of packets to send on to a peer for the three seconds following a handshake. The source of these packets is left as a future exercise.)
