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	b3d65ba943	tstest/natlab: refactor, expose a Packet type. HandlePacket and Inject now receive/take Packets. This is a handy container for the packet, and the attached Trace method can be used to print traces from custom packet handlers that integrate nicely with natlab's internal traces.

David Anderson	5eedbcedd1	tstest/natlab: add a stateful firewall. The firewall provides a ProcessPacket handler, and implements an address-and-port endpoint dependent firewall that allows all traffic to egress from the trusted interface, and only allows inbound traffic if corresponding outbound traffic was previously seen.

David Anderson	0ed9f62ed0	tstest/natlab: provide inbound interface to HandlePacket. Requires a bunch of refactoring so that Networks only ever refer to Interfaces that have been attached to them, and Interfaces know about both their Network and Machine.

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
David Anderson	0aea087766	tstest/natlab: add PacketHandler and Inject. Together, they can be used to plug custom packet processors into Machines. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	73db7e99ab	tstest/natlab: make Machine constructible directly. This is a prelude to adding more fields, which would otherwise become more unnamed function params. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	d94593e884	tstest/natlab: unregister conn4 if registration of conn6 fails. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	d7bc4ec029	tstest/natlab: use common helper for conn registration. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	80a14c49c6	tstest/natlab: add comments to conns4/conns6. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	622c0d0cb3	tstest/natlab: print trace data when NATLAB_TRACE is set. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	1d4f9852a7	tstest/natlab: correctly handle dual-stacked PacketConns. Adds a test with multiple networks, one of which is v4-only. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	771eb05bcb	tstest/natlab: first network attached becomes the default route. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	f2e5da916a	tstest/natlab: allow sensible default construction of networks. Add a test for LAN->LAN traffic. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
