Brad Fitzpatrick	d55fdd4669	wgengine/magicsock: update, flesh out a TODO	4 years ago
Brad Fitzpatrick	d96d26c22a	wgengine/filter: don't spam logs on dropped outgoing IPv6 ICMP or IPv4 IGMP The OS (tries) to send these but we drop them. No need to worry the user with spam that we're dropping it. Fixes #402 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago

Brad Fitzpatrick	3e3c24b8f6	wgengine/packet: add IPVersion field, don't use IPProto to note version As prep for IPv6 log spam fixes in a future change. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago

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
Brad Fitzpatrick	ec4feaf31c	cmd/cloner, tailcfg: fix nil vs len 0 issues, add tests, use for Hostinfo Also use go:generate and https://golang.org/s/generatedcode header style. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago

David Anderson	9265296b33	wgengine/magicsock: don't deadlock on shutdown if sending blocks. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	0249236cc0	ipn/ipnstate: record assigned Tailscale IPs. wgengine/magicsock: use ipnstate to find assigned Tailscale IPs. Signed-off-by: David Anderson <danderson@tailscale.com>	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	5455c64f1d	wgengine/magicsock: add a test for two facing endpoint-independent NATs. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	f794493b4f	wgengine/magicsock: explicitly check path discovery, add a firewall test. The test proves that active discovery can traverse two facing firewalls. 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
David Anderson	a2b4ad839b	net/netcheck: lower the hairpin check timeout to 100ms. This single check is the long pole for netcheck, and significantly slows down magicsock tests. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	25288567ec	net/netcheck: centralize all clock values in one place. This makes it easier to see how long a netcheck might take, and what the slow bits might be. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	5a370d545a	tstest/natlab: drop packets that can't be routed in a LAN. LANs are authoritative for their prefixes, so we should not bounce packets back and forth to the default gateway in that case. 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	4970e771ab	wgengine: add debug knob to disable the watchdog during debugging It launches goroutines and interferes with panic-based debugging, obscuring stacks.	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	a89d610a3d	wgengine/tstun: move sync.Pool to package global sync.Pools should almost always be packate globals, even though in this case we only have exactly 1 TUN device anyway, so it matters less. Still, it's unusual to see a Pool that's not a package global, so move it.	4 years ago
