Brad Fitzpatrick	f99f970dc1	tstest/natlab/vnet: rename some things for clarity The bad naming (which had only been half updated with the IPv6 changes) tripped me up in the earlier change. Updates #13038 Change-Id: I65ce07c167e8219d35b87e1f4bf61aab4cac31ff Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 months ago
Brad Fitzpatrick	0157000cab	tstest/natlab: fix IPv6 tests, remove TODOs The reason they weren't working was because the cmd/tta agent in the guest was dialing out to the test and the vnet couldn't map its global unicast IPv6 address to a node as it was just using a map[netip.Addr]node and blindly trusting the node was populated. Instead, it was nil, so the agent connection fetching didn't work for its RoundTripper and the test could never drive the node. That map worked for IPv4 but for IPv6 we need to use the method that takes into account the node's IPv6 SLAAC address. Most call sites had been converted but I'd missed that one. Also clean up some debug, and prohibit nodes' link-local unicast addresses from dialing 2000::/3 directly for now. We can allow that to be configured opt-in later (some sort of IPv6 NAT mode. Whatever it's called.) That mode was working on accident, but was confusing: Linux would do source address selection from link local for the first few seconds and then after SLAAC and DAD, switch to using the global unicast source address. Be consistent for now and force it to use the global unicast. Updates #13038 Change-Id: I85e973aaa38b43c14611943ff45c7c825ee9200a Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 months ago
Brad Fitzpatrick	6dd1af0d1e	tstest/natlab: refactor HandleEthernetPacketForRouter a bit Move all the UDP handling to its own func to remove a bunch of "if isUDP" checks in a bunch of blocks.

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>	3 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>	3 months ago

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.
