Brad Fitzpatrick	addda5b96f	wgengine/magicsock: fix watchdog timeout on Close when IPv6 not available The blockForeverConn was only using its sync.Cond one side. Looks like it was just forgotten. Fixes #3671 Change-Id: I4ed0191982cdd0bfd451f133139428a4fa48238c Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	28bf53f502	wgengine/magicsock: reduce disco ping heartbeat aggressiveness a bit Bigger changes coming later, but this should improve things a bit in the meantime. Rationale: * 2 minutes -> 45 seconds: 2 minutes was overkill and never considered phones/battery at the time. It was totally arbitrary. 45 seconds is also arbitrary but is less than 2 minutes. * heartbeat from 2 seconds to 3 seconds: in practice this meant two packets per second (2 pings and 2 pongs every 2 seconds) because the other side was also pinging us every 2 seconds on their own. That's just overkill. (see #540 too) So in the worst case before: when we sent a single packet (say: a DNS packet), we ended up sending 61 packets over 2 minutes: the 1 DNS query and then then 60 disco pings (2 minutes / 2 seconds) & received the same (1 DNS response + 60 pongs). Now it's 15. In 1.22 we plan to remove this whole timer-based heartbeat mechanism entirely. The 5 seconds to 6.5 seconds change is just stretching out that interval so you can still miss two heartbeats (other 3 + 3 seconds would be greater than 5 seconds). This means that if your peer moves without telling you, you can have a path out for 6.5 seconds now instead of 5 seconds before disco finds a new one. That will also improve in 1.22 when we start doing UDP+DERP at the same time when confidence starts to go down on a UDP path.

Brad Fitzpatrick	7d9b1de3aa	netcheck,portmapper,magicsock: ignore some UDP write errors on Linux Treat UDP send EPERM errors as a lost UDP packet, not something super fatal. That's just the Linux firewall preventing it from going out. And add a leaf package net/neterror for that (and future) policy that all three packages can share, with tests.

Josh Bleecher Snyder	b3d6704aa3	wgengine/magicsock: fix data race on endpoint.discoKey endpoint.discoKey is protected by endpoint.mu. endpoint.sendDiscoMessage was reading it without holding the lock. This showed up in a CI failure and is readily reproducible locally. The fix is in two parts. First, for Conn.enqueueCallMeMaybe, eliminate the one-line helper method endpoint.sendDiscoMessage; call Conn.sendDiscoMessage directly. This makes it more natural to read endpoint.discoKey in a context in which endpoint.mu is already held. Second, for endpoint.sendDiscoPing, explicitly pass the disco key as an argument. Again, this makes it easier to read endpoint.discoKey in a context in which endpoint.mu is already held. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago

Josh Bleecher Snyder	5a60781919	wgengine/magicsock: increase TestDiscokeyChange connection timeout I believe that this should eliminate the flakiness. If GitHub CI manages to be even slower that can be believed (and I can believe a lot at this point), then we should roll this back and make some more invasive changes.

Josh Bleecher Snyder	773af7292b	wgengine/magicsock: simplify peerMap.upsertEndpoint We can do the "maybe delete" check unilaterally: In the case of an insert, both oldDiscoKey and ep.discoKey will be the zero value. And since we don't use pi again, we can skip giving it a name, which makes scoping clearer. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
