Christine Dodrill	ede8ec1e20	tstest/integration/vms: split up test framework into files (#2396 ) My spatial memory functions poorly with large files and the vms_test.go file recently surpassed the point where it functions adequately. This patch splits up vms_test.go into more files to make my spatial memory function like I need it to. Signed-off-by: Christine Dodrill <xe@tailscale.com>	3 years ago
Christine Dodrill	1f2a877c61	tstest/integration/testcontrol: add ipv6 support (#2394 ) Split from https://github.com/tailscale/tailscale/pull/2376. This adds IPv6 support to testcontrol so each member of the tailscale network gets an IPv6 address too. Signed-off-by: Christine Dodrill <xe@tailscale.com>	3 years ago
Brad Fitzpatrick	61e8fd4698	cmd/derpprobe: move from cmd/derper/derpprobe Because our corp build system is confused by nested binaries. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
maddie	d976a84d7e	derp: allow self node when verifying clients Fixes #2408 Signed-off-by: Maddie Zhan <maddie.zhan@cynovan.com>	3 years ago

David Crawshaw	87481282eb	ipn: another controlplane synonym This one doesn't bother me so much, as long term we want a synonym here. Fixes #2384 Fixes #2386 Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	3 years ago
Brad Fitzpatrick	4c0494185b	derp: remove "fine for now" intentional slow memory leak from derp server It was once believed that it might be useful. It wasn't. We never used it. Remove it so we don't slowly leak memory. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
David Crawshaw	c84d7baf98	cmd/tailscale/cli: factor out more up code for testing In theory, some of the other table-driven tests could be moved into this form now but I didn't want to disturb too much good test code. Includes a commented-out test for #2384 that is currently failing. Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	3 years ago

Brad Fitzpatrick	7e7c4c1bbe	tailcfg: break DERPNode.DERPTestPort into DERPPort & InsecureForTests The DERPTestPort int meant two things before: which port to use, and whether to disable TLS verification. Users would like to set the port without disabling TLS, so break it into two options. Updates #1264 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago

Christine Dodrill	afbd35482d	tstest/integration/vms: add NixOS unstable back (#2330 ) The upstream NixOS issue was fixed. https://github.com/NixOS/nixpkgs/issues/128783 Signed-off-by: Christine Dodrill <xe@tailscale.com>	3 years ago
Christine Dodrill	33cacb5284	tstest/integration/vms: unbreak nixos builds (#2372 ) To avoid the generated nixos disk images from becoming immune from the GC, I delete the symlink to the nix store at the end of tests. `t.Cleanup` runs at the end of a test. I changed this part of the code to have a separate timer for how long it takes to run NixOS builds, but I did that by using a subtest. This means that it was creating the NixOS image, deleting its symlink and then trying to use that symlink to find the resulting disk image, making the whole thing ineffectual. This was a mistake. I am reverting this change made in https://github.com/tailscale/tailscale/pull/2360 to remove this layer of subtesting. Signed-off-by: Christine Dodrill <xe@tailscale.com>	3 years ago
Christine Dodrill	b90f149f5e	Run tests on integration test changes (#2373 ) Hopefully this will catch situations like https://github.com/tailscale/tailscale/pull/2372 Signed-off-by: Christine Dodrill <xe@tailscale.com>	3 years ago
Josh Bleecher Snyder	7a08c159e6	safesocket: create the test socket in a temp dir This allows the test to be run inside a mounted filesystem, which I'm doing now as a I develop on a linux VM. Fixes #2367. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Christine Dodrill	254fc7885b	Revert "tstest/integration/vms: end-to-end UDP test (#2361 )" (#2364 ) This reverts commit `dc78be12c5`.	3 years ago
Christine Dodrill	dc78be12c5	tstest/integration/vms: end-to-end UDP test (#2361 ) This tests incoming and outgoing UDP traffic. It would test incoming UDP traffic however our socks server doesn't seem to allow for connecting to destinations over UDP. When the socks server gets that support the incoming test should pass without issue. Signed-off-by: Christine Dodrill <xe@tailscale.com>	3 years ago
Christine Dodrill	a19eea965f	tstest/integration/vms: use an in-process logcatcher (#2360 ) This adapts the existing in-process logcatcher from tstest/integration into a public type and uses it on the side of testcontrol. This also fixes a bug in the Alpine Linux OpenRC unit that makes every value in `/etc/default/tailscaled` exported into tailscaled's environment, a-la systemd [Service].EnviromentFile.

Brad Fitzpatrick	440566c5d2	net/interfaces: trim getPACWindows whitespace before parsing URL Fixes #2357 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Christine Dodrill	1e83b97498	tstest/integration/vms: outgoing SSH test (#2349 ) This does a few things: 1. Rewrites the tests so that we get a log of what individual tests failed at the end of a test run. 2. Adds a test that runs an HTTP server via the tester tailscale node and then has the VMs connect to that over Tailscale. 3. Dials the VM over Tailscale and ensures it answers SSH requests. 4. Other minor framework refactoring. Signed-off-by: Christine Dodrill <xe@tailscale.com>	3 years ago
Christine Dodrill	97279a0fe0	tstest/integration/vms: add Oracle Linux image (#2328 ) Oracle Linux[1] is a CentOS fork. It is not very special. I am adding it to the integration jungle because I am adding it to pkgs and the website directions. [1]: https://www.oracle.com/linux/ Signed-off-by: Christine Dodrill <xe@tailscale.com>	3 years ago
Brad Fitzpatrick	a9fc583211	cmd/tailscale/cli: document the web subcommand a bit more Fixes #2326 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Josh Bleecher Snyder	0ad92b89a6	net/tstun: fix data races To remove some multi-case selects, we intentionally allowed sends on closed channels (`cc23049cd2`). However, we also introduced concurrent sends and closes, which is a data race. This commit fixes the data race. The mutexes here are uncontended, and thus very cheap.

Brad Fitzpatrick	7d417586a8	tstest/integration: help bust cmd/go's test caching It was caching too aggressively, as it didn't see our deps due to our running "go install tailscaled" as a child process. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago

Christine Dodrill	a8360050e7	tstest/integration/vms: make first end to end test (#2332 ) This makes sure `tailscale status` and `tailscale ping` works.

Josh Bleecher Snyder	7f095617f2	internal/deephash: 8 bits of output is not enough Running hex.Encode(b, b) is a bad idea. The first byte of input will overwrite the first two bytes of output. Subsequent bytes have no impact on the output. Not related to today's IPv6 bug, but...wh::ps. This caused us to spuriously ignore some wireguard config updates.

Josh Bleecher Snyder	cc23049cd2	net/tstun: remove multi-case selects from hot code Every TUN Read went through several multi-case selects. We know from past experience with wireguard-go that these are slow and cause scheduler churn. The selects served two purposes: they separated errors from data and gracefully handled shutdown. The first is fairly easy to replace by sending errors and data over a single channel. The second, less so. We considered a few approaches: Intricate webs of channels, global condition variables. They all get ugly fast. Instead, let's embrace the ugly and handle shutdown ungracefully. It's horrible, but the horror is simple and localized.
