Brad Fitzpatrick	c3c4c05331	tstest/integration/testcontrol: remove a vestigial unused parameter Back in the day this testcontrol package only spoke the nacl-boxed-based control protocol, which used this. Then we added ts2021, which didn't, but still sometimes used it. Then we removed the old mode and didn't remove this parameter in `2409661a0d`.

Brad Fitzpatrick	c3306bfd15	control/controlhttp/controlhttpserver: split out Accept to its own package Otherwise all the clients only using control/controlhttp for the ts2021 HTTP client were also pulling in WebSocket libraries, as the server side always needs to speak websockets, but only GOOS=js clients speak it. This doesn't yet totally remove the websocket dependency on Linux because Linux has a envknob opt-in to act like GOOS=js for manual testing and force the use of WebSockets for DERP only (not control). We can put that behind a build tag in a future change to eliminate the dep on all GOOSes.

Nick Khyl	d837e0252f	wf/firewall: allow link-local multicast for permitted local routes when the killswitch is on on Windows When an Exit Node is used, we create a WFP rule to block all inbound and outbound traffic, along with several rules to permit specific types of traffic. Notably, we allow all inbound and outbound traffic to and from LocalRoutes specified in wgengine/router.Config. The list of allowed routes always includes routes for internal interfaces, such as loopback and virtual Hyper-V/WSL2 interfaces, and may also include LAN routes if the "Allow local network access" option is enabled. However, these permitting rules do not allow link-local multicast on the corresponding interfaces. This results in broken mDNS/LLMNR, and potentially other similar issues, whenever an exit node is used. In this PR, we update (wf.Firewall).UpdatePermittedRoutes() to create rules allowing outbound and inbound link-local multicast traffic to and from the permitted IP ranges, partially resolving the mDNS/LLMNR and .local name resolution issue. Since Windows does not attempt to send mDNS/LLMNR queries if a catch-all NRPT rule is present, it is still necessary to disable the creation of that rule using the disable-local-dns-override-via-nrpt nodeAttr.

Brad Fitzpatrick	a01b545441	control/control{client,http}: don't noise dial localhost:443 in http-only tests `1eaad7d3de` regressed some tests in another repo that were starting up a control server on `http://127.0.0.1:nnn`. Because there was no https running, and because of a bug in `1eaad7d3de` (which ended up checking the recently-dialed-control check twice in a single dial call), we ended up forcing only the use of TLS dials in a test that only had plaintext HTTP running. Instead, plumb down support for explicitly disabling TLS fallbacks and use it only when running in a test and using `http` scheme control plane URLs to 127.0.0.1 or localhost. This fixes the tests elsewhere. Updates #13597 Change-Id: I97212ded21daf0bd510891a278078daec3eebaa6 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 months ago

Nothing in Tailscale depends on this (yet?), but it makes debugging in VMs behind natlab easier (e.g. you can ping all nodes), and other things might depend on this in the future. Mostly I'm trying to flesh out the IPv6 support in natlab now that we can write vnet tests.

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	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.

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.
