Christine Dodrill	e0f0d10672	tstest/integration/vms: log to t.Logf directly (#2147 ) Previously we used t.Logf indirectly via package log. This worked, but it was not ideal for our needs. It could cause the streams of output to get crossed. This change uses a logger.FuncWriter every place log.Output was previously used, which will more correctly write log information to the right test output stream.

Brad Fitzpatrick	082cc1b0a7	tstest/integration: reenable TestAddPingRequest Failure understood now; see: https://github.com/tailscale/tailscale/pull/2088#issuecomment-859896598 As of `333e9e75d4`, PingRequest is now safe for the server to send multiple times, without fear of the client handling it multiple times. Fixes #2079 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Denton Gentry	c61d777705	tstest/integration: disable TestAddPingRequest Failing often now, we don't want people to get used to routinely ignoring test failures. Can be re-enabled when https://github.com/tailscale/tailscale/issues/2079 is resolved. Signed-off-by: Denton Gentry <dgentry@tailscale.com>	3 years ago
Christine Dodrill	8b2b899989	tstest/integration: test Alpine Linux (#2098 ) Alpine Linux[1] is a minimal Linux distribution built around musl libc. It boots very quickly, requires very little ram and is as close as you can get to an ideal citizen for testing Tailscale on musl. Alpine has a Tailscale package already[2], but this patch also makes it easier for us to provide an Alpine Linux package off of pkgs in the future. Alpine only offers Tailscale on the rolling-release edge branch. [1]: https://alpinelinux.org/ [2]: https://pkgs.alpinelinux.org/packages?name=tailscale&branch=edge Updates #1988 Signed-off-by: Christine Dodrill <xe@tailscale.com>	4 years ago
Brad Fitzpatrick	0affcd4e12	tstest/integration: add some debugging for TestAddPingRequest flakes This fails pretty reliably with a lot of output now showing what's happening: TS_DEBUG_MAP=1 go test --failfast -v -run=Ping -race -count=20 ./tstest/integration --verbose-tailscaled I haven't dug into the details yet, though.

Christine Dodrill	b402e76185	.github/workflows: add integration test with a custom runner (#2044 ) This runner is in my homelab while we muse about a better, more permanent home for these tests. Updates #1988 Signed-off-by: Christine Dodrill <xe@tailscale.com>	4 years ago
Christine Dodrill	622dc7b093	tstest/integration/vms: download images from s3 (#2035 ) This makes integration tests pull pristine VM images from Amazon S3 if they don't exist on disk. If the S3 fetch fails, it will fall back to grabbing the image from the public internet. The VM images on the public internet are known to be updated without warning and thusly change their SHA256 checksum. This is not ideal for a test that we want to be able to fire and forget, then run reliably for a very long time. This requires an AWS profile to be configured at the default path. The S3 bucket is rigged so that the requester pays. The VM images are currently about 6.9 gigabytes. Please keep this in mind when running these tests on your machine. Documentation was added to the integration test folder to aid others in running these tests on their machine. Some wording in the logs of the tests was altered.

Christine Dodrill	3f1405fa2a	tstest/integration/vms: bump images, fix caching bug (#2052 ) Before this redownloaded the image every time. Now it only redownloads it when it needs to. Signed-off-by: Christine Dodrill <xe@tailscale.com>	4 years ago
Simeng He	0141390365	tstest/integration/testcontrol: add Server.AddPingRequest Signed-off-by: Simeng He <simeng@tailscale.com>	4 years ago
Christine Dodrill	adaecd83c8	tstest/integration/vms: add DownloadImages test to download images (#2039 ) The image downloads can take a significant amount of time for the tests. This creates a new test that will download every distro image into the local cache in parallel, optionally matching the distribution regex. Updates #1988 Signed-off-by: Christine Dodrill <xe@tailscale.com>	4 years ago
Christine Dodrill	607b7ab692	tstest/integration/vms: aggressively re-verify shasums (#2050 ) I've run into a couple issues where the tests time out while a VM image is being downloaded, making the cache poisoned for the next run. This moves the hash checking into its own function and calls it much sooner in the testing chain. If the hash check fails, the OS is redownloaded.

Christine Dodrill	6ce77b8eca	tstest/integration/vms: log qemu output (#2047 ) Most of the time qemu will output nothing when it is running. This is expected behavior. However when qemu is unable to start due to some problem, it prints that to either stdout or stderr. Previously this output wasn't being captured. This patch captures that output to aid in debugging qemu issues. Updates #1988 Signed-off-by: Christine Dodrill <xe@tailscale.com>	4 years ago

Christine Dodrill	0a655309c6	tstest/integration/vms: only build binaries once (#2042 ) Previously this built the binaries for every distro. This is a bit overkill given we are using static binaries. This patch makes us only build once. There was also a weird issue with how processes were being managed. Previously we just killed qemu with Process.Kill(), however that was leaving behind zombies. This has been mended to not only kill qemu but also waitpid() the process so it doesn't become a zombie. Updates #1988 Signed-off-by: Christine Dodrill <xe@tailscale.com>	4 years ago
Christine Dodrill	a282819026	tstest/integration/vms: fix OpenSUSE Leap 15.1 (#2038 ) The OpenSUSE 15.1 image we are using (and conseqentially the only one that is really available easily given it is EOL) has cloud-init hardcoded to use the OpenStack metadata thingy. Other OpenSUSE Leap images function fine with the NoCloud backend, but this one seems to just not work with it. No bother, we can just pretend to be OpenStack. Thanks to Okami for giving me an example OpenStack configuration seed image. Updates #1988 Signed-off-by: Christine Dodrill <xe@tailscale.com>	4 years ago
Christine Dodrill	4da5e79c39	tstest/integration/vms: test on Arch Linux (#2040 ) Arch is a bit of a weirder distro, however as a side effect it is much more of a systemd purist experience. Adding it to our test suite will make sure that we are working in the systemd happy path. Updates #1988 Signed-off-by: Christine Dodrill <xe@tailscale.com>	4 years ago
Christine Dodrill	ca96357d4b	tstest/integration/vms: add OpenSUSE Leap 15.3 (#2026 ) This distro is about to be released. OpenSUSE has historically had the least coverage for functional testing, so this may prove useful in the future. Signed-off-by: Christine Dodrill <xe@tailscale.com>	4 years ago
Christine Dodrill	2802a01b81	tstest/integration/vms: test vms as they are ready (#2022 ) Instead of testing all the VMs at once when they are all ready, this patch changes the testing logic so that the vms are tested as soon as they register with testcontrol. Also limit the amount of VM ram used at once with the `-ram-limit` flag. That uses a semaphore to guard resource use. Also document CentOS' sins.

Christine Dodrill	36cb69002a	tstest/integration/vms: regex-match distros using a flag (#2021 ) If you set `-distro-regex` to match a subset of distros, only those distros will be tested. Ex: $ go test -run-vm-tests -distro-regex='opensuse' Signed-off-by: Christine Dodrill <xe@tailscale.com>	4 years ago
Christine Dodrill	e1b994f7ed	tstest/integration/vms: maintain distro info (#2020 ) This lets us see the names of distros in our tests. Updates #1988 Signed-off-by: Christine Dodrill <xe@tailscale.com>	4 years ago
Brad Fitzpatrick	fa548c5b96	tstest/integration/vms: fix bindhost lookup (#2012 ) Don't try to do heuristics on the name. Use the net/interfaces package which we already have to do this sort of stuff. Fixes #2011 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Christine Dodrill	14c1113d2b	tstest/integration/vms: copy locally built binaries (#2006 ) Instead of pulling packages from pkgs.tailscale.com, we should use the tailscale binaries that are local to this git commit. This exposes a bit of the integration testing stack in order to copy the binaries correctly. This commit also bumps our version of github.com/pkg/sftp to the latest commit. If you run into trouble with yaml, be sure to check out the commented-out alpine linux image complete with instructions on how to use it.

Christine Dodrill	4cfaf489ac	tstest/integration/vms: t.Log for VM output (#2007 ) Previously we spewed a lot of output to stdout and stderr, even when `-v` wasn't set. This is sub-optimal for various reasons. This patch shunts that output to test logs so it only shows up when `-v` is set. Updates #1988 Signed-off-by: Christine Dodrill <xe@tailscale.com>	4 years ago
Christine Dodrill	1f72b6f812	tstest/integration/vms: use dynamically discovered bindhost (#1992 ) Instead of relying on a libvirtd bridge address that you probably won't have on your system. Updates #1988 Signed-off-by: Christine Dodrill <xe@tailscale.com>	4 years ago

Josh Bleecher Snyder	25df067dd0	all: adapt to opaque netaddr types This commit is a mishmash of automated edits using gofmt: gofmt -r 'netaddr.IPPort{IP: a, Port: b} -> netaddr.IPPortFrom(a, b)' -w . gofmt -r 'netaddr.IPPrefix{IP: a, Port: b} -> netaddr.IPPrefixFrom(a, b)' -w . gofmt -r 'a.IP.Is4 -> a.IP().Is4' -w . gofmt -r 'a.IP.As16 -> a.IP().As16' -w . gofmt -r 'a.IP.Is6 -> a.IP().Is6' -w . gofmt -r 'a.IP.As4 -> a.IP().As4' -w . gofmt -r 'a.IP.String -> a.IP().String' -w . And regexps: \w(.)\.Port = (.) -> $1 = $1.WithPort($2) \w(.)\.IP = (.) -> $1 = $1.WithIP($2) And lots of manual fixups. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago

Filippo Valsorda	39f7a61e9c	tstest/staticcheck: import the main package to fix "go mod tidy" Importing the non-main package was missing some dependencies that "go mod tidy" would then cleanup.

Josh Bleecher Snyder	138055dd70	tstest/natlab: use net.ErrClosed instead of a new error Upstream wireguard-go decided to use errors.Is(err, net.ErrClosed) instead of checking the error string. It also provided an unsafe linknamed version of net.ErrClosed for clients running Go 1.15. Switch to that. This reduces the time required for the wgengine/magicsock tests on my machine from ~35s back to the ~13s it was before `456cf8a376`.
