Jonathan Nobels	8fad8c4b9b	tstest/tailmac: add customized macOS virtualization tooling (#13146 ) updates tailcale/corp#22371 Adds custom macOS vm tooling. See the README for the general gist, but this will spin up VMs with unixgram capable network interfaces listening to a named socket, and with a virtio socket device for host-guest communication. We can add other devices like consoles, serial, etc as needed. The whole things is buildable with a single make command, and everything is controllable via the command line using the TailMac utility. This should all be generally functional but takes a few shortcuts with error handling and the like. The virtio socket device support has not been tested and may require some refinement.

Brad Fitzpatrick	d985da207f	tstest/natlab/vnet: fix one-by-one from earlier numbering change `84adfa1ba3` made MAC addresses 1-based too, but didn't adjust this IP address calculation which was based on the MAC address Updates #13038 Change-Id: Idc112b303b0b85f41fe51fd61ce1c0d8a3f0f57e Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 months ago
Brad Fitzpatrick	84adfa1ba3	tstest/natlab/vnet: standardize on 1-based naming of nodes, networks, MACs We had a mix of 0-based and 1-based nodes and MACs in logs.

Brad Fitzpatrick	10d0ce8dde	tstest/natlab: get tailscaled logs from gokrazy via syslog Using https://github.com/gokrazy/gokrazy/pull/275 This is much lower latency than logcatcher, which is higher latency and chunkier. And this is better than getting it via 'tailscale debug daemon-logs', which misses early interesting logs.

Brad Fitzpatrick	a61825c7b8	cmd/tta, vnet: add host firewall, env var support, more tests In particular, tests showing that #3824 works. But that test doesn't actually work yet; it only gets a DERP connection. (why?)

Maisem Ali	12764e9db4	natlab: add NodeAgentClient This adds a new NodeAgentClient type that can be used to invoke the LocalAPI using the LocalClient instead of handcrafted URLs. However, there are certain cases where it does make sense for the node agent to provide more functionality than whats possible with just the LocalClient, as such it also exposes a http.Client to make requests directly.

Josh Bleecher Snyder	25df067dd0	all: adapt to opaque netaddr types This commit is a mishmash of automated edits using gofmt: gofmt -r 'netaddr.IPPort{IP: a, Port: b} -> netaddr.IPPortFrom(a, b)' -w . gofmt -r 'netaddr.IPPrefix{IP: a, Port: b} -> netaddr.IPPrefixFrom(a, b)' -w . gofmt -r 'a.IP.Is4 -> a.IP().Is4' -w . gofmt -r 'a.IP.As16 -> a.IP().As16' -w . gofmt -r 'a.IP.Is6 -> a.IP().Is6' -w . gofmt -r 'a.IP.As4 -> a.IP().As4' -w . gofmt -r 'a.IP.String -> a.IP().String' -w . And regexps: \w(.)\.Port = (.) -> $1 = $1.WithPort($2) \w(.)\.IP = (.) -> $1 = $1.WithIP($2) And lots of manual fixups. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
Josh Bleecher Snyder	d31eff8473	tstest/natlab: use net.ErrClosed We are now on 1.16. And wgconn.NetErrClosed has been removed upstream. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
Josh Bleecher Snyder	138055dd70	tstest/natlab: use net.ErrClosed instead of a new error Upstream wireguard-go decided to use errors.Is(err, net.ErrClosed) instead of checking the error string. It also provided an unsafe linknamed version of net.ErrClosed for clients running Go 1.15. Switch to that. This reduces the time required for the wgengine/magicsock tests on my machine from ~35s back to the ~13s it was before `456cf8a376`.

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	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
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

David Anderson	88e8456e9b	wgengine/magicsock: add a connectivity test for facing firewalls.

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.
