Brad Fitzpatrick	58b721f374	wgengine/magicsock: deflake some tests with an ugly hack ... Starting with fe68841dc7, some e2e tests got flaky. Rather than debug them (they're gnarly), just revert to the old behavior as far as those tests are concerned. The tests were somehow using magicsock without a private key and expecting it to do ... something. My goal with fe68841dc7 was to stop log spam and unnecessary work I saw on the iOS app when when stopping the app. Instead, only stop doing that work on any transition from once-had-a-private-key to no-longer-have-a-private-key. That fixes what I wanted to fix while still making the mysterious e2e tests happy.	4 years ago

David Anderson	c3958898f1	tstest/natlab: be a bit more lenient during test shutdown. ... There is a race in natlab where we might start shutdown while natlab is still running a goroutine or two to deliver packets. This adds a small grace period to try and receive it before continuing shutdown. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	7578c815be	wgengine/magicsock: give pinger a more generous packet timeout. ... The first packet to transit may take several seconds to do so, because setup rates in wgengine may result in the initial WireGuard handshake init to get dropped. So, we have to wait at least long enough for a retransmit to correct the fault. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	c3994fd77c	derp: remove OnlyDisco option. ... Active discovery lets us introspect the state of the network stack precisely enough that it's unnecessary, and dropping the initial DERP packets greatly slows down tests. Additionally, it's unrealistic since our production network will never deliver _only_ discovery packets, it'll be all or nothing. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago

David Anderson	f582eeabd1	wgengine/magicsock: add a test for active path discovery. ... Uses natlab only, because the point of this active discovery test is going to be that it should get through a lot of obstacles. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
Brad Fitzpatrick	37903a9056	wgengine/magicsock: fix occasional deadlock on Conn.Close on c.derpStarted ... The deadlock was: * Conn.Close was called, which acquired c.mu * Then this goroutine scheduled: if firstDerp { startGate = c.derpStarted go func() { dc.Connect(ctx) close(c.derpStarted) }() } * The getRegion hook for that derphttp.Client then ran, which also tries to acquire c.mu. This change makes that hook first see if we're already in a closing state and then it can pretend that region doesn't exist.	4 years ago
Brad Fitzpatrick	fe68841dc7	wgengine/magicsock: log better with less spam on transition to stopped state ... Required a minor test update too, which now needs a private key to get far enough to test the thing being tested.	4 years ago

Brad Fitzpatrick	16a9cfe2f4	wgengine: configure wireguard peers lazily, as needed ... wireguard-go uses 3 goroutines per peer (with reasonably large stacks & buffers). Rather than tell wireguard-go about all our peers, only tell it about peers we're actively communicating with. That means we need hooks into magicsock's packet receiving path and tstun's packet sending path to lazily create a wireguard peer on demand from the network map. This frees up lots of memory for iOS (where we have almost nothing left for larger domains with many users). We should ideally do this in wireguard-go itself one day, but that'd be a pretty big change. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago

Brad Fitzpatrick	a6559a8924	wgengine/magicsock: run test DERP in mode where only disco packets allowed ... So we don't accidentally pass a NAT traversal test by having DERP pick up our slack when we really just wanted DERP as an OOB messaging channel.	4 years ago

Dmytro Shynkevych	380ee76d00	wgengine/magicsock: make time.Sleep in runDerpReader respect cancellation. ... Before this patch, the 250ms sleep would not be interrupted by context cancellation, which would result in the goroutine sometimes lingering in tests (100ms grace period).

Dmytro Shynkevych	891898525c	wgengine/magicsock: make receive from didCopy respect cancellation. ... Very rarely, cancellation occurs between a successful send on derpRecvCh and a call to copyBuf on the receiving side. Without this patch, this situation results in <-copyBuf blocking indefinitely.

Brad Fitzpatrick	a2267aae99	wgengine: only launch pingers for peers predating the discovery protocol ...

David Anderson	45578b47f3	tstest/natlab: refactor PacketHandler into a larger interface. ... The new interface lets implementors more precisely distinguish local traffic from forwarded traffic, and applies different forwarding logic within Machines for each type.

Brad Fitzpatrick	f5f3885b5b	wgengine/magicsock: bunch of misc discovery path cleanups ... * fix tailscale status for peers using discovery * as part of that, pull out disco address selection into reusable and testable discoEndpoint.addrForSendLocked * truncate ping/pong logged hex txids in half to eliminate noise * move a bunch of random time constants into named constants with docs * track a history of per-endpoint pong replies for future use & status display * add "send" and " got" prefix to discovery message logging immediately before the frame type so it's easier to read than searching for the "<-" or "->" arrows earlier in the line; but keep those as the more reasily machine readable part for later.

Brad Fitzpatrick	275a20f817	wgengine/magicsock: keep discoOfAddr populated, use it for findEndpoint ... Update the mapping from ip:port to discokey, so when we retrieve a packet from the network, we can find the same conn.Endpoint that we gave to wireguard-go previously, without making it think we've roamed.

Brad Fitzpatrick	77d3ef36f4	wgengine/magicsock: hook up discovery messages, upgrade to LAN works ... Ping messages now go out somewhat regularly, pong replies are sent, and pong replies are now partially handled enough to upgrade off DERP to LAN. CallMeMaybe packets are sent & received over DERP, but aren't yet handled. That's next (and regular maintenance timers), and then WAN should work. Updates #483	4 years ago

Brad Fitzpatrick	7b3c0bb7f6	wgengine/magicsock: fix crash reading DERP packet ... Starting at yesterday's e96f22e560 (convering some UDPAddrs to IPPorts), Conn.ReceiveIPv4 could return a nil addr, which would make its way through wireguard-go and blow up later. The DERP read path wasn't initializing the addr result parameter any more, and wgRecvAddr wasn't checking it either. Fixes #515	4 years ago

Brad Fitzpatrick	a975e86bb8	wgengine/magicsock: add new endpoint type used for discovery-supporting peers ... This adds a new magicsock endpoint type only used when both sides support discovery (that is, are advertising a discovery key). Otherwise the old code is used. So far the new code only communicates over DERP as proof that the new code paths are wired up. None of the actually discovery messaging is implemented yet. Support for discovery (generating and advertising a key) are still behind an environment variable for now. Updates #483	4 years ago
Brad Fitzpatrick	103c06cc68	wgengine/magicsock: open discovery naclbox messages from known peers ... And track known peers. Doesn't yet do anything with the messages. (nor does it send any yet) Start of docs on the message format. More will come in subsequent changes. Updates #483	4 years ago
Brad Fitzpatrick	23e74a0f7a	wgengine, magicsock, tstun: don't regularly STUN when idle (mobile only for now) ... If there's been 5 minutes of inactivity, stop doing STUN lookups.

And make the DERP map support multiple nodes per region with clients picking the first one that's available.

Avery Pennarun	08acb502e5	Add tstest.PanicOnLog(), and fix various problems detected by this. ... If a test calls log.Printf, 'go test' horrifyingly rearranges the output to no longer be in chronological order, which makes debugging virtually impossible. Let's stop that from happening by making log.Printf panic if called from any module, no matter how deep, during tests. This required us to change the default error handler in at least one http.Server, as well as plumbing a bunch of logf functions around, especially in magicsock and wgengine, but also in logtail and backoff. To add insult to injury, 'go test' also rearranges the output when a parent test has multiple sub-tests (all the sub-test's t.Logf is always printed after all the parent tests t.Logf), so we need to screw around with a special Logf that can point at the "current" t (current_t.Logf) in some places. Probably our entire way of using subtests is wrong, since 'go test' would probably like to run them all in parallel if you called t.Parallel(), but it definitely can't because the're all manipulating the shared state created by the parent test. They should probably all be separate toplevel tests instead, with common setup/teardown logic. But that's a job for another time. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	4 years ago
Dmytro Shynkevych	33b2f30cea	wgengine: wrap tun.Device to support filtering and packet injection (#358) ... Right now, filtering and packet injection in wgengine depend on a patch to wireguard-go that probably isn't suitable for upstreaming. This need not be the case: wireguard-go/tun.Device is an interface. For example, faketun.go implements it to mock a TUN device for testing. This patch implements the same interface to provide filtering and packet injection at the tunnel device level, at which point the wireguard-go patch should no longer be necessary. This patch has the following performance impact on i7-7500U @ 2.70GHz, tested in the following namespace configuration: ┌────────────────┐ ┌─────────────────────────────────┐ ┌────────────────┐ │ $ns1 │ │ $ns0 │ │ $ns2 │ │ client0 │ │ tailcontrol, logcatcher │ │ client1 │ │ ┌─────┐ │ │ ┌──────┐ ┌──────┐ │ │ ┌─────┐ │ │ │vethc│───────┼────┼──│vethrc│ │vethrs│──────┼─────┼──│veths│ │ │ ├─────┴─────┐ │ │ ├──────┴────┐ ├──────┴────┐ │ │ ├─────┴─────┐ │ │ │10.0.0.2/24│ │ │ │10.0.0.1/24│ │10.0.1.1/24│ │ │ │10.0.1.2/24│ │ │ └───────────┘ │ │ └───────────┘ └───────────┘ │ │ └───────────┘ │ └────────────────┘ └─────────────────────────────────┘ └────────────────┘ Before: --------------------------------------------------- | TCP send | UDP send | |------------------------|------------------------| | 557.0 (±8.5) Mbits/sec | 3.03 (±0.02) Gbits/sec | --------------------------------------------------- After: --------------------------------------------------- | TCP send | UDP send | |------------------------|------------------------| | 544.8 (±1.6) Mbits/sec | 3.13 (±0.02) Gbits/sec | --------------------------------------------------- The impact on receive performance is similar.
