Maisem Ali	31b5239a2f	tstest/natlab/vnet: flush and sync pcap file after every packet So that we can view the pcap as we debug interactively. Updates #13038 Signed-off-by: Maisem Ali <maisem@tailscale.com>	2 months ago
Brad Fitzpatrick	e5fd36ad78	tstest/natlab: respect NATTable interface's invalid-means-drop everywhere And sprinkle some more docs around. Updates #13038 Change-Id: Ia2dcf567b68170481cc2094d64b085c6b94a778a Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 months ago
Brad Fitzpatrick	aa42ae9058	tstest/natlab: make a new virtualIP type in prep for IPv6 support All the magic service names with virtual IPs will need IPv6 variants. Pull this out in prep.

Brad Fitzpatrick	5a99940dfa	tstest/natlab/vnet: explicitly ignore PCP and SSDP UDP queries So we don't log about them when verbose logging is enabled. Updates #13038 Change-Id: I925bc3a23e6c93d60dd4fb4bf6a4fdc5a326de95 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 months ago

Brad Fitzpatrick	3904e4d175	cmd/tta, tstest/natlab/vnet: remove unneeded port 124 log hack, add log buffer The natlab Test Agent (tta) still had its old log streaming hack in place where it dialed out to anything on TCP port 124 and those logs were streamed to the host running the tests. But we'd since added gokrazy syslog streaming support, which made that redundant. So remove all the port 124 stuff. And then make sure we log to stderr so gokrazy logs it to syslog. Also, keep the first 1MB of logs in memory in tta too, exported via localhost:8034/logs for interactive debugging. That was very useful during debugging when I added IPv6 support. (which is coming in future PRs) Updates #13038 Change-Id: Ieed904a704410b9031d5fd5f014a73412348fa7f Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 months ago
Jonathan Nobels	1191eb0e3d	tstest/natlab: add unix address to writer for dgram mode updates tailcale/corp#22371 For dgram mode, we need to store the write addresses of the client socket(s) alongside the writer functions and the write operation needs to use WriteToUnix. Unix also has multiple clients writing to the same socket, so the serve method is modified to handle packets from multiple mac addresses. Cleans up a bit of cruft from the initial tailmac tooling commit. Now all the macOS packets are belong to us. Signed-off-by: Jonathan Nobels <jonathan@tailscale.com>	2 months ago
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>	2 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.
