2021-01-13Switch uses of os.Getenv that check for empty string to os.LookupEnv.Dean Deng
Whether the variable was found is already returned by syscall.Getenv. os.Getenv drops this value while os.Lookupenv passes it along. PiperOrigin-RevId: 351674032
2021-01-13testutil: Create a `multiLogger` that logs to multiple `Loggers`.Etienne Perot
This is useful when using the shell library in order to log to both the test log and the standard logs. PiperOrigin-RevId: 351673465
2021-01-12Delete shim v1Fabricio Voznika
gvisor-containerd-shim is not compatible with containerd 1.1 or earlier. Starting from containerd 1.2, shim v2 is the preferred interface. PiperOrigin-RevId: 351485556
2021-01-08Create console test library.Etienne Perot
This creates a TTY pair and runs `/bin/sh` in interactive mode within it. It provides useful helper functions to interact with the shell and read the output of commands run within it. This is meant to be used for testing upcoming changes allowing `runsc exec` to work in `-detach=false -tty=true` mode. PiperOrigin-RevId: 350841006
2021-01-05Add benchmarks targets to BuildKite.Adin Scannell
This includes minor fix-ups: * Handle SIGTERM in runsc debug, to exit gracefully. * Fix cmd.debug.go opening all profiles as RDONLY. * Fix the test name in fio_test.go, and encode the block size in the test. PiperOrigin-RevId: 350205718
2020-12-29Simplify profiling and benchmarks.Adin Scannell
- Tweak the benchmarks to work with b.N where appropriate. In many cases, b.N was simply being ignored. This creates an implicit dependency in the user passing a reasonable benchtime (less than or equal to the actual runtime of the test, or using the X syntax) otherwise the test runs forever. - In cases where the above is impossible, explicitly set benchtime from the test wrapper, to prevent the above behavior (tensorflow). - Drop the *Reverse variants, which are simply hey benchmarks. We should just add a hey benchmark. The platforms benchmarks already include a native platform, and thus these benchmarks are incredibly confusing. (In other words, BenchmarkNginxReverse has nothing to do with an nginx benchmark for runsc.) - Remove the redunant Harness object, which contains no state, in order to slightly simplify the code. - Make Block and Heap profiling actually work, but setting appropriate runtime parameters (and plumbing them through the config). - Split the profiling into two phases: start and stop, since some will need to be started early, and others will need to happen at the end.

PiperOrigin-RevId: 345399936
2020-12-02Make testutil.RandomID safe for concurrent usesZeling Feng
testutil.RandomID was using Rand.Read which is not safe for concurrent use. It caused name conflicts in packetimpact tests when they are run in parallel. Adding a mutex to protect the Rand.Read operation. PiperOrigin-RevId: 345360062
2020-11-30Do not start a ContainerExec twiceZeling Feng
ContainerExecStart and ContainerExecAttach both call the /exec/id/start API endpoint. PiperOrigin-RevId: 344946627
2020-11-30Ensure containerd is used from installed location.Adin Scannell
Currently, if containerd is installed locally via tools/installers/containerd, then it will not necessarily be used if containerd is installed in the system path. This means that the existing containerd tests are all likely broken. Also, use libbtrfs-dev instead of btrfs-tools, which is not actually required. PiperOrigin-RevId: 344879109

2020-09-17[testing] Use container address to talk to server running inside container.Ayush Ranjan
Docker does not have IPv6 port forwarding as tracked by the following issue: https://github.com/moby/moby/issues/11518 So when running bazel itself inside a docker container, we can not use the host port bindings to communicate with sockets inside the container. This was causing integration tests and image tests to fail when run through our Makefile targets. PiperOrigin-RevId: 332355051
2020-09-02Add support to run packetimpact tests against FuchsiaZeling Feng
blaze test <test_name>_fuchsia_test will run the corresponding packetimpact test against fuchsia. PiperOrigin-RevId: 329835290
2020-08-26Make flag propagation automaticFabricio Voznika
Use reflection and tags to provide automatic conversion from Config to flags. This makes adding new flags less error-prone, skips flags using default values (easier to read), and makes tests correctly use default flag values for test Configs. Updates #3494 PiperOrigin-RevId: 328662070
2020-08-24Remove go profiling flag from dockerutil.Zach Koopmans
Go profiling was removed from runsc debug in a previous change. PiperOrigin-RevId: 328203826

2020-08-11Mark integration tests as passing in VFS2 except CheckpointRestore.Zach Koopmans
Mark all tests passing for VFS2 in: image_test integration_test There's no way to do negative look ahead/behind in golang test regex, so check if the tests uses VFS2 and skip CheckPointRestore if it does. PiperOrigin-RevId: 326050915
2020-08-10Speed up iptables testsKevin Krakauer
//test/iptables:iptables_test runs 30 seconds faster on my machine. * Using contexts instead of many smaller timeouts makes the tests less likely to flake and removes unnecessary complexity. * We also use context to properly shut down concurrent goroutines and the test container. * Container logs are always logged.

We skip gVisor tests for now, as ip6tables aren't yet implemented.
2020-07-26Add profiling to dockerutilZach Koopmans
Adds profiling with `runsc debug` or pprof to dockerutil. All targets using dockerutil should now be able to use profiling. In addition, modifies existing benchmarks to use profiling. PiperOrigin-RevId: 323298634
2020-07-22make connect(2) fail when dest is unreachableKevin Krakauer
Previously, ICMP destination unreachable datagrams were ignored by TCP endpoints. This caused connect to hang when an intermediate router couldn't find a route to the host. This manifested as a Kokoro error when Docker IPv6 was enabled. The Ruby image test would try to install the sinatra gem and hang indefinitely attempting to use an IPv6 address. Fixes #3079.

2020-07-09Update shim to build using bazel.Adin Scannell
The go.mod dependency tree for the shim was somehow contradictory. After resolving these issues (e.g. explicitly imported k8s 1.14, pulling a specific dbus version), and adding all dependencies, the shim can now be build as part of the regular bazel tree. As part of this process, minor cleanup was done in all the source files: headers were standardized (and include "The gVisor Authors" in addition to the "The containerd Authors" if originally derived from containerd sources), and comments were cleaned up to meet coding standards. This change makes the containerd installation dynamic, so that multiple versions can be tested, and drops the static installer for the VM image itself. This change also updates test/root/crictl_test.go and related utilities, so that the containerd tests can be run on any version (and in cases where it applies, they can be run on both v1 and v2 as parameterized tests).
2020-07-08Move all tests to new docker API.Zach Koopmans
Moves following to new dockerutil API: - //test/e2e:integration_test - //test/image:image_test - //test/iptables:iptables_test - //test/root:root_test - //test/packetimpact:packetimpact_test PiperOrigin-RevId: 320253118
2020-07-08Enable shards in runtime test runner.Ayush Ranjan
Fixed an issue with the runtime test runner which enables us to run tests in shards. We had to touch the status file as indicated by an env var. PiperOrigin-RevId: 320236205

2020-04-24Standardize all Docker images.Adin Scannell
This change moves all Docker images to a standard location, and abstracts the build process so that they can be maintained in an automated fashion. This also allows the images to be architecture-independent. All images will now be referred to by the test framework via the canonical `gvisor.dev/images/<name>`, where `<name>` is a function of the path within the source tree. In a subsequent change, continuous integration will be added so that the images will always be correct and available locally. In the end, using `bazel` for Docker containers is simply not possible. Given that we already have the need to use `make` with the base container (for Docker), we extend this approach to get more flexibility. This change also adds a self-documenting and powerful Makefile that is intended to replace the collection of scripts in scripts. Canonical (self-documenting) targets can be added here for targets that understand which images need to be loaded and/or built. PiperOrigin-RevId: 308322438
2020-04-23Simplify Docker test infrastructure.Adin Scannell
This change adds a layer of abstraction around the internal Docker APIs, and eliminates all direct dependencies on Dockerfiles in the infrastructure. A subsequent change will automated the generation of local images (with efficient caching). Note that this change drops the use of bazel container rules, as that experiment does not seem to be viable. PiperOrigin-RevId: 308095430
