Brad Fitzpatrick	c4d0237e5c	tstest/natlab: add dual stack with blackholed IPv4 This reproduces the bug report from https://github.com/tailscale/tailscale/issues/13346 It does not yet fix it. Updates #13346 Change-Id: Ia5af7b0481a64a37efe259c798facdda6d9da618 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 months ago
Brad Fitzpatrick	7e88d6712e	tstest/natlab/vnet: add syslog tests Updates #13038 Change-Id: I4ac96cb0a9e46a2fb1e09ddedd3614eb006c2c8c Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 months ago
Brad Fitzpatrick	82c2c5c597	tstest/natlab/vnet: add more tests This adds tests for DNS requests, and ignoring IPv6 packets on v4-only networks. No behavior changes. But some things are pulled out into functions. And the mkPacket helpers previously just for tests are moved into non-test code to be used elsewhere to reduce duplication, doing the checksum stuff automatically.

Brad Fitzpatrick	73b3c8fc8c	tstest/natlab/vnet: add IPv6 all-nodes support This adds support for sending packets to 33:33:00:00:01 at IPv6 multicast address ff02::1 to send to all nodes. 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	ff1d0aa027	tstest/natlab/vnet: start adding tests And refactor some of vnet.go for testability. The only behavioral change (with a new test) is that ethernet broadcasts no longer get sent back to the sender.

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.

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>	3 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?)
