Brad Fitzpatrick	cdfea347d0	wgengine: update for tailscale/wireguard-go API changes * update to new HandshakeDone signature * use new Device.IpcGetOperationFiltered call to avoid sending allowed_ips See `dd6c1c8fe1`	4 years ago
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. This allows Machines to be packet forwarders, which didn't quite work with the implementation of Inject. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
Dmytro Shynkevych	19867b2b6d	tstun: remove buggy-looking log line. This log line looks buggy, even though lacking a filter is expected during bringup. We already know if we forget to SetFilter: it breaks the magicsock test, so no useful information is lost. Resolves #559. Signed-off-by: Dmytro Shynkevych <dmytro@tailscale.com>	4 years ago
Wendi Yu	c3736250a4	wgengine: fix macos staticcheck errors (#557 ) Signed-off-by: Wendi <wendi.yu@yahoo.ca>	4 years ago
Dmytro Shynkevych	3b36400e35	tsdns: response to type ANY queries Signed-off-by: Dmytro Shynkevych <dmytro@tailscale.com>	4 years ago
Dmytro Shynkevych	2f15894a10	wgengine/magicsock: wait for derphttp client goroutine to exit Signed-off-by: Dmytro Shynkevych <dmytro@tailscale.com>	4 years ago
Dmytro Shynkevych	30bbbe9467	wgengine/router: dns: unify on *BSD, multimode on Linux, Magic DNS (#536 ) Signed-off-by: Dmytro Shynkevych <dmytro@tailscale.com>	4 years ago
Dmytro Shynkevych	61abab999e	cmd/tailscaled: graceful shutdown (#534 ) Signed-off-by: Dmytro Shynkevych <dmytro@tailscale.com>	4 years ago
David Anderson	88e8456e9b	wgengine/magicsock: add a connectivity test for facing firewalls. The test demonstrates that magicsock can traverse two stateful firewalls facing each other, that each require localhost to initiate connections. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	1f7b1a4c6c	wgengine/magicsock: rearrange TwoDevicePing test for future natlab tests. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	977381f9cc	wgengine/magicsock: make trivial natlab test pass. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
Brad Fitzpatrick	6c74065053	wgengine/magicsock, tstest/natlab: start hooking up natlab to magicsock Also adds ephemeral port support to natlab. Work in progress. Pairing with @danderson.	4 years ago
Dmytro Shynkevych	21d1dbfce0	wgengine/tsdns: local DNS server for testing Signed-off-by: Dmytro Shynkevych <dmytro@tailscale.com>	4 years ago
Dmytro Shynkevych	248d28671b	tsdns: fix race in delegate Signed-off-by: Dmytro Shynkevych <dmytro@tailscale.com>	4 years ago

Brad Fitzpatrick	de875a4d87	wgengine/magicsock: remove DisableSTUNForTesting	4 years ago
Dmytro Shynkevych	67ebba90e1	tsdns: dual resolution mode, IPv6 support (#526 ) This change adds to tsdns the ability to delegate lookups to upstream nameservers. This is crucial for setting Magic DNS as the system resolver. Signed-off-by: Dmytro Shynkevych <dmytro@tailscale.com>	4 years ago
Brad Fitzpatrick	ce1b52bb71	wgengine/monitor: fix other potential crashes on Linux Never return "nil, nil" anymore. The caller expected a usable interface now. I missed some of these earlier. Also, handle address deletion now. Updates #532	4 years ago
Brad Fitzpatrick	4b75a27969	wgengine/monitor: fix crash on Linux on type 21 messages Fixes #532	4 years ago
Brad Fitzpatrick	724ad13fe1	wgengine/tstun: fix alignment of 64-bit atomic field We had a test for it, but no 32-bit builder apparently. :( Fixes #529	4 years ago
Brad Fitzpatrick	4db60a8436	wgengine/monitor: parse Linux netlink messages, ignore our own events Fixes tailscale/corp#412 ("flood of link change events at start-up") Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	742b8b44a8	net/tsaddr: new package to hold Tailscale-specific IPs/ranges And update existing callers with (near) duplicated cases.	4 years ago
Brad Fitzpatrick	5c6d8e3053	netcheck, tailcfg, interfaces, magicsock: survey UPnP, NAT-PMP, PCP Don't do anything with UPnP, NAT-PMP, PCP yet, but see how common they are in the wild. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	6196b7e658	wgengine/magicsock: change API to not permit disco key changes Generate the disco key ourselves and give out the public half instead. Fixes #525	4 years ago
Brad Fitzpatrick	5132edacf7	wgengine/magicsock: fix data race from undocumented wireguard-go requirement Endpoints need to be Stringers apparently. Fixes tailscale/corp#422	4 years ago
Brad Fitzpatrick	630379a1d0	cmd/tailscale: add tailscale status region name, last write, consistently star There's a lot of confusion around what tailscale status shows, so make it better: show region names, last write time, and put stars around DERP too if active. Now stars are always present if activity, and always somewhere.	4 years ago
Brad Fitzpatrick	9a8700b02a	wgengine/magicsock: add discoEndpoint heartbeat Updates #483	4 years ago
Brad Fitzpatrick	9f930ef2bf	wgengine/magicsock: remove the discoEndpoint.timers map It ended up being more complicated than it was worth.	4 years ago
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. Updates #483	4 years ago
Dmytro Shynkevych	e9643ae724	wgengine: prevent log after exit in watchdog test Signed-off-by: Dmytro Shynkevych <dmytro@tailscale.com>	4 years ago
Dmytro Shynkevych	16b2bbbbbb	wgengine: close in reverse order of bringup Signed-off-by: Dmytro Shynkevych <dmytro@tailscale.com>	4 years ago
Brad Fitzpatrick	6c70cf7222	wgengine/magicsock: stop ping timeout timer on pong receipt, misc log cleanup Updates #483	4 years ago
Brad Fitzpatrick	c52905abaa	wgengine/magicsock: log less on no-op disco route switches Also, renew trustBestAddrUntil even if latency isn't better.	4 years ago
Brad Fitzpatrick	0f0ed3dca0	wgengine/magicsock: clean up discovery logging Updates #483	4 years ago
Brad Fitzpatrick	056fbee4ef	wgengine/magicsock: add TS_DEBUG_OMIT_LOCAL_ADDRS knob to force STUN use only For debugging.	4 years ago
Brad Fitzpatrick	e03cc2ef57	wgengine/magicsock: populate discoOfAddr upon receiving ping frames Updates #483	4 years ago
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. (We did, but we're not using its roaming.) Updates #483	4 years ago
Brad Fitzpatrick	77e89c4a72	wgengine/magicsock: handle CallMeMaybe discovery mesages Roughly feature complete now. Testing and polish remains. Updates #483	4 years ago
Brad Fitzpatrick	710ee88e94	wgengine/magicsock: add timeout on discovery pings, clean up state Updates #483	4 years ago
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	9b8ca219a1	wgengine/magicsock: remove allocs in UDP write, use new netaddr.PutUDPAddr The allocs were only introduced yesterday with a TODO. Now they're gone again.	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	47b4a19786	wgengine/magicsock: use netaddr.ParseIPPort instead of net.ResolveUDPAddr	4 years ago
Brad Fitzpatrick	f7124c7f06	wgengine/magicsock: start of discoEndpoint state tracking Updates #483	4 years ago
Brad Fitzpatrick	92252b0988	wgengine/magicsock: add a little LRU cache for netaddr.IPPort lookups And while plumbing, a bit of discovery work I'll need: the endpointOfAddr map to map from validated paths to the discoEndpoint. Not being populated yet. Updates #483	4 years ago
Brad Fitzpatrick	2d6e84e19e	net/netcheck, wgengine/magicsock: replace more UDPAddr with netaddr.IPPort	4 years ago
Brad Fitzpatrick	9070aacdee	wgengine/magicsock: minor comments & logging & TODO changes	4 years ago
Brad Fitzpatrick	e96f22e560	wgengine/magicsock: start handling disco message, use netaddr.IPPort more Updates #483	4 years ago
Brad Fitzpatrick	a83ca9e734	wgengine/magicsock: cache precomputed nacl/box shared keys Updates #483	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
