2021-03-03Add checklocks analyzer.Bhasker Hariharan
This validates that struct fields if annotated with "// checklocks:mu" where "mu" is a mutex field in the same struct then access to the field is only done with "mu" locked. All types that are guarded by a mutex must be annotated with // +checklocks:<mutex field name> For more details please refer to README.md. PiperOrigin-RevId: 360729328
2021-02-25Strip all non-numeric characters from version.Adin Scannell
This will fix debian packaging. Updates #5510 PiperOrigin-RevId: 359563378
2021-02-08[go-marshal] Add dynamic tag in go_marshal.Ayush Ranjan
This makes it easier to implement dynamically sized types in go-marshal. You really only need to implement MarshalBytes, UnmarshalBytes and SizeBytes to implement the entire interface. By using the `dynamic` tag, the autogenerator will generate the rest of the methods for us. This change also simplifies how KernelIPTGetEntries implements Marshallable using the newly added utility. PiperOrigin-RevId: 356397114
2021-02-03Remove gazelle noise patchTamir Duberstein
Confirmed gazelle generates no significant noise. Fix documented gazelle invocation while I'm here. PiperOrigin-RevId: 355452758
2021-02-02Update go-tools to 2020.2.1Tamir Duberstein
...and a bunch of other things as I worked through the rot. Notably: - Upgrade to bazel 4.0.0 - Upgrade to Go 1.15.7 Remove go_branch stderr suppression; this made it quite difficult to see what was failing while developing this patch. PiperOrigin-RevId: 355257833
2021-02-02Remove go_tool_library references.Adin Scannell
This is required only for the built-in bazel nogo functionality. Since we roll these targets manually via the wrappers, we don't need to use go_tool_library. The inconsistent use of these targets leads to conflicting instantiations of go_default_library and go_tool_library, which both contain the same output files. PiperOrigin-RevId: 355184975
2021-02-01Fix empty Packages file for APT repository.Adin Scannell
This change also adds an extra sanity check to the make_apt.sh script, in order to ensure that this simple mistake does not occur again. PiperOrigin-RevId: 355101754
2021-02-01Remove Go cache on failure.Adin Scannell
It's unclear why permissions wind up corrupted, but these can be cleared on any failure, similar to the bazel cache itself: https://buildkite.com/gvisor/pipeline/builds/2304#_ PiperOrigin-RevId: 355057421
2021-01-22[infra] Fix Build Github action failure.Ayush Ranjan
The GH Build action has been failing with the error message: ``` --- BUILD -c opt //runsc tee: /proc/self/fd/2: No such device or address ``` tee /dev/fd/2 seems to be the canonical way of copying stdin to stderr. So use that instead. PiperOrigin-RevId: 353259087
2021-01-12Fix Go branch building.Adin Scannell
Files removed from the working tree were not being properly removed from the branch, leading to symbol conflicts while building. This requires the change to 'git add --all' in the tools/go_branch.sh script. But why was this not caught by CI? The "git clean -f" command by default only cleans files in the current working directory. In order to clean the whole tree recursively, we need to specify a pathspec, which is ".". In addition to these fixes, re-add the "go tests" command to help prevent this from happening again, since merges on the Go branch will happen in GitHub actions for simplicity. The Go test is retained in BuildKite. PiperOrigin-RevId: 351503804
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
2021-01-12Drop shutdown in docker run.Adin Scannell
This can race and cause issues. Instead, a manual shutdown can be done via 'bazel-shutdown' if required for specific cases. The ARM64 builds are now done using cross-compilation, so this hack is not necessary. PiperOrigin-RevId: 351477908
2021-01-12Fix simple mistakes identified by goreportcard.Adin Scannell
These are primarily simplification and lint mistakes. However, minor fixes are also included and tests added where appropriate. PiperOrigin-RevId: 351425971
2021-01-11Fix Go branch for arm64.Adin Scannell
This requires several changes: * Templates must preserve relevant tags. * Pagetables templates are split into two targets, each preserving tags. * The binary VDSO is similarly split into two targets, with some juggling. * The top level tools/go_branch.sh now does a crossbuild of ARM64 as well, and checks and merges the results of the two branches together. Fixes #5178 PiperOrigin-RevId: 351304330
2021-01-08Support releasing aarch64 builds.Adin Scannell

2021-01-06Include objdump failures in test output.Michael Pratt
We log a warning if objdump fails, but this appears in the build log, not test log, which can make it hard to notice. Include it with the actual escape output as context on "(possible)" to make it more clear when something is wrong. PiperOrigin-RevId: 350355759

2021-01-05Add YAML validation for configuration files.Adin Scannell
For validation, the "on" key in existing YAML files is changed to a literal string. In the YAML spec, on is a keyword which encodes a boolean value, so without relying on a specific implementation the YAML files are technically not encoding an object that complies with the specification. PiperOrigin-RevId: 350172147

PiperOrigin-RevId: 349616845
2020-12-30Add BuildKite annotations for failures and profiles.Adin Scannell
This change cleans up some minor Makefile issues, and adds support for BuildKite annotations on failure and on profiles being generated. These annotations will make failures very clear and link to the artifacts. This change is a stepping stone for aggregating coverage data from all individual test jobs, as this will also happen in .buildkite/annotate.sh. PiperOrigin-RevId: 349606598
2020-12-30Use a stable ordering for generated types.Adin Scannell
Otherwise this pollutes the 'go' branch and doesn't conform to standards for generate bazel files. PiperOrigin-RevId: 349605037

A few images were broken with respect to aarch64. We should now be able to run push-all-images with ARCH=aarch64 as part of the regular continuous integration builds, and add aarch64 smoke tests (via user emulation for now) to the regular test suite (future). PiperOrigin-RevId: 346685462

2020-12-09Refactor the Makefile to avoid recursive Make.Adin Scannell
Recursive make is difficult to follow and debug. Drop this by using internal functions, which, while difficult, are easier than trying to following recursive invokations. Further simplify the Makefile by collapsing the image bits and removing the tools/vm directory, which is effectively unused. Fixes #4952 PiperOrigin-RevId: 346569133

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

2020-11-23Clean up build output.Adin Scannell
This change also simplifies and documents the build_cmd pipeline, and reduces general noise for debugging Makefile issues. It also drops the mapping for /etc/docker/daemon.json, which if it does not exist initially will create this as a directory (causing lots of confusion and breaks). PiperOrigin-RevId: 343932456

2020-10-28[infra] Deflake Go / generate (pull_request) GitHub action.Ayush Ranjan
As you can see https://github.com/google/gvisor/commits/master, there are a lot of red commits. This is because the Go / generate GitHub action flakes. On merge, two variants of this workflow run: - one triggered by the pull request (copybara force pushes to the PR right before merge) - one triggered by the push (merge) If the push action ends up finishing before the pull request action can run go_branch.sh, then the changes that go_branch.sh makes is already pushed to the remote go branch. Consequently, the pull request action ends up having nothing to commit causing this action to fail. This change also fixes lint warnings. Now we skip running the go_branch.sh if we find that our current working commit has already been committed to remote. PiperOrigin-RevId: 339586760

2020-10-26Add nogo configuration.Adin Scannell
This splits the nogo rules into a separate configuration yaml file, and allows for multiple files to be provided. Because attrs cannot be passed down to aspects, this required that all findings are propagated up the aspect Provider. This doesn't mean that any extra work must be done, just that this information must be carried through the graph, and some additional starlark complexity is required. PiperOrigin-RevId: 339076357
