2020-10-19Remove legacy bazel configurations.Adin Scannell
Using the newer bazel rules necessitates a transition from proto1 to proto2. In order to resolve the incompatibility between proto2 and gogoproto, the cri runtimeoptions proto must be vendored. Further, some of the semantics of bazel caching changed during the transition. It is now necessary to: - Ensure that :gopath depends only on pure library targets, as the propagation of go_binary build attributes (pure, static) will affected the generated files (though content remains the same, there are conflicts with respect to the gopath). - Update bazel.mk to include the possibility of binaries in the bazel-out directory, as it will now put runsc and others there. This required some refinements to the mechanism of extracting paths, since some the existing regex resulted in false positives. - Change nogo rules to prevent escape generation on binary targets. For some reason, the newer version of bazel attempted to run the nogo analysis on the binary targets, which fails due to the fact that objdump does not work on the final binary. This must be due to a change in the semantics of aspects in bazel3. PiperOrigin-RevId: 337958324
2020-10-07Add staticcheck and staticstyle analyzers.Adin Scannell
This change also adds support to go_stateify for detecting an appropriate receiver name, avoiding a large number of false positives. PiperOrigin-RevId: 335994587
2020-08-07Remove old benchmark tools.Zach Koopmans
Remove the old benchmark-tools directory, including imports in the WORKSPACE file and associated bazel rules. The new Golang benchmark-tools can be found at //test/benchmarks and it is functionally equivalent, excepting syscall_test which can be found in //test/perf/linux. PiperOrigin-RevId: 325529075
2020-07-30Implement neighbor unreachability detection for ARP and NDP.Sam Balana
This change implements the Neighbor Unreachability Detection (NUD) state machine, as per RFC 4861 [1]. The state machine operates on a single neighbor in the local network. This requires the state machine to be implemented on each entry of the neighbor table. This change also adds, but does not expose, several APIs. The first API is for performing basic operations on the neighbor table: - Create a static entry - List all entries - Delete all entries - Remove an entry by address The second API is used for changing the NUD protocol constants on a per-NIC basis to allow Neighbor Discovery to operate over links with widely varying performance characteristics. See [RFC 4861 Section 10][2] for the list of constants. Finally, the last API is for allowing users to subscribe to NUD state changes. See [RFC 4861 Appendix C][3] for the list of edges.

PiperOrigin-RevId: 321053634
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).

2020-04-23Simplify 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
2020-04-20Add internal nogo analysis & checkescape tool.Adin Scannell
See tools/nogo/README.md. The checkescape tool is able to perform recursive escape analysis, using the actual generated binary to confirm the results produced by the compiler itself. As an initial use case, this replaces the manual escape analysis tests used for go_marshal, and validates that the CopyIn and CopyOut paths will not require any allocation or stack splits.

2019-12-12Add iptables testing framework.Kevin Krakauer
It would be preferrable to test iptables via syscall tests, but there are some problems with that approach: * We're limited to loopback-only, as syscall tests involve only a single container. Other link interfaces (e.g. fdbased) should be tested. * We'd have to shell out to call iptables anyways, as the iptables syscall interface itself is too large and complex to work with alone. * Running the Linux/native version of the syscall test will require root, which is a pain to configure, is inherently unsafe, and could leave host iptables misconfigured. Using the go_test target allows there to be no new test runner. PiperOrigin-RevId: 285274275
2019-12-02Import benchmark-tools to main repository.Zach Koopmans
This has adapted for use with bazel from the original commit a26e93769ebefd82593a43e22fb13a09717cfa6d. In particular, the style has been made consistent with internal python style guidelines, and the packages (including the main entrypoint) have been refactored in order to allow bazel testing targets.

2019-08-13Bump Bazel to v0.28.0Nicolas Lacasse
The new version has a change in behavior when using a custom platform: * Old behavior: rules that don't require a toolchain used host_platform, no matter what execution platforms are specified. * New behavior: rules that don't require a toolchain use standard platform resolution that starts with execution platforms. As part of this change, we cannot use the "extra_exectution_platforms" flag provided by the default bazelrc. I got rid of the default bazelrc file, and made our custom .bazelrc as minimal as possible. PiperOrigin-RevId: 263176802
2019-07-29Rate limit the unimplemented syscall event handler.Nicolas Lacasse
This introduces two new types of Emitters: 1. MultiEmitter, which will forward events to other registered Emitters, and 2. RateLimitedEmitter, which will forward events to a wrapped Emitter, subject to given rate limits. The methods in the eventchannel package itself act like a multiEmitter, but is not actually an Emitter. Now we have a DefaultEmitter, and the methods in eventchannel simply forward calls to the DefaultEmitter. The unimplemented syscall handler now uses a RateLimetedEmitter that wraps the DefaultEmitter. PiperOrigin-RevId: 260612770

2019-06-10Add introspection for Linux/AMD64 syscallsIan Lewis
Adds simple introspection for syscall compatibility information to Linux/AMD64. Syscalls registered in the syscall table now have associated metadata like name, support level, notes, and URLs to relevant issues. Syscall information can be exported as a table, JSON, or CSV using the new 'runsc help syscalls' command. Users can use this info to debug and get info on the compatibility of the version of runsc they are running or to generate documentation. PiperOrigin-RevId: 252558304
