2020-02-19Add basic microbenchmarks.Adin Scannell
PiperOrigin-RevId: 296104390
2020-02-19Handle situations where go-marshal generates an empty test file.gVisor bot
This can happen due to conditional compilation, where a subset of the source files contain no marshallable types. go-marshal is still required to write an output file in these cases, since bazel defines the output package before calling go-marshal. PiperOrigin-RevId: 296074321
2020-02-18go-marshal: Stop complaining about files with no +marshal types.gVisor bot
Since we tag entire packages as marshallable, due to conditional compiling for different architectures we can end up with sets of source files that don't contain any marshallable types. It's safe to silently ignore this scenario. PiperOrigin-RevId: 295831871
2020-02-15Ensure Marshallable.SizeBytes() always works on a typed nil pointer.gVisor bot
This lets go-marshal replace various calls to binary.Size() throughout the sentry without requiring concrete objects. PiperOrigin-RevId: 295299965
2020-02-14Generate implementation of io.WriterTo via go-marshal.gVisor bot
PiperOrigin-RevId: 295269654
2020-02-14Add a minimal binary target for escape analysis on go-marshal.gVisor bot
Note that this is not an automated test. PiperOrigin-RevId: 295238672
2020-02-14Fix various issues related to enabling go-marshal.gVisor bot
- Add missing build tags to files in the abi package. - Add the marshal package as a sentry dependency, allowed by deps_test. - Fix an issue with our top-level go_library BUILD rule, which incorrectly shadows the variable containing the input set of source files. This caused the expansion for the go_marshal clause to silently omit input files. - Fix formatting when copying build tags to gomarshal-generated files. - Fix a bug with import statement collision detection in go-marshal. PiperOrigin-RevId: 295112284
2020-02-13Ensure the marshalled object doesn't escape.gVisor bot
Add new Marshallable interface methods CopyIn/CopyOut, which can be directly called on the marshalled object, avoiding an interface indirection. Such indirections are problematic because they always cause the marshalled object to escape. PiperOrigin-RevId: 295028010
2020-02-13Call py_requirement with named argument for optional kwarg.gVisor bot
PiperOrigin-RevId: 294930818
2020-02-11Stateify: register types with full package namesgVisor bot
This is to avoid conflicts with types that share the same [short] package and type names, e.g. proc.smapsData exist in pkg/sentry/fs/proc and pkg/sentry/fsimpl/proc. Updates #1663 PiperOrigin-RevId: 294485146
2020-02-10Rename build to builddefs and minor build clean-up.Adin Scannell
The name 'bazel' also doesn't work because bazel will treat it specially. Fixes #1807 PiperOrigin-RevId: 294321221
2020-02-10Move x86 state definition to its own file.Brad Burlage
PiperOrigin-RevId: 294271541

PiperOrigin-RevId: 294265019
2020-02-06Add logic to run from baked images.Zach Koopmans
Change adds the following: - logic to run from "baked images". See [GVISOR_DIR]/tools/images - installers which install modified files from a workspace. This allows users to run benchmarks while modifying runsc. - removes the --preemptible tag from built GCE instances. Preemptible instances are much more likely to be preempted on startup, which manifests for the user as a failed benchmark. I don't currently have a way to detect if a VM has been preempted that will work for this change. https://cloud.google.com/compute/docs/instances/preemptible#preemption_process https://cloud.google.com/compute/docs/instances/preemptible#preemption_selection PiperOrigin-RevId: 293697949
2020-02-05Add notes to relevant tests.Adin Scannell
These were out-of-band notes that can help provide additional context and simplify automated imports. PiperOrigin-RevId: 293525915
2020-02-04Automatically propagate tags for stateify and marshal.Adin Scannell
Note that files will need to be appropriately segmented in order for the mechanism to work, in suffixes implying special tags. This only needs to happen for cases where marshal or state structures are defined, which should be rare and mostly architecture specific. PiperOrigin-RevId: 293231579
2020-01-30Simplify testing link rules.Adin Scannell
PiperOrigin-RevId: 292458933
2020-01-27Update package locations.Adin Scannell
Because the abi will depend on the core types for marshalling (usermem, context, safemem, safecopy), these need to be flattened from the sentry directory. These packages contain no sentry-specific details. PiperOrigin-RevId: 291811289
2020-01-27Fix licenses.Adin Scannell
The preferred Copyright holder is "The gVisor Authors". PiperOrigin-RevId: 291786657
2020-01-27Standardize on tools directory.Adin Scannell
PiperOrigin-RevId: 291745021
2020-01-22Add tools for generating images.Adin Scannell
This formalizes the adhoc scripts previously in kokoro. The image targets can be used by e.g. benchmarks in order to automated image prepation. PiperOrigin-RevId: 290982744
2020-01-08Github bug reviverFabricio Voznika
For everyone's joy, this is a tool that reopens issues that have been closed, but are still referenced by TODOs in the code. The idea is to run it in Kokoro nightly. Kokoro changes are coming up next. PiperOrigin-RevId: 288789560

2019-11-25Fix typo in go_branch.sh script.Adin Scannell
With the ticks, the command `master` is actually be run and the output included (which is nothing). This is confusing, as we actually mean to say "master" in the description of the Go branch. PiperOrigin-RevId: 282426081
2019-11-21Import and structure cleanup.Adin Scannell
PiperOrigin-RevId: 281795269
2019-11-18release: fix tag scriptAdin Scannell
The tag script, when not run interactively, will fail without a provided commit message (since it now uses annotated tags). For now, use a trivial message. In the future, this could be extended to provide automated release notes. PiperOrigin-RevId: 281112651
2019-11-05Fix repository build scripts.Adin Scannell
This fixes a number of issues with the repository build process: * Fix the overall structure of the repository. * Fix the debian package description. * Fix the broken version number for packages. * Update the digest algorithm used for signing the release. I've validated that installation works from a separate staging bucket. Updates #852 PiperOrigin-RevId: 278716914
2019-10-31Add LICENSE and AUTHORS to the go branch.Adin Scannell
Also, construct the README directly so that edits can be made. PiperOrigin-RevId: 277782095
2019-10-28Add tools/go_stateify to support Arm64Bin Lu
2 jobs were finished in this patch: 1, add a new attribute to specify the target platform. 2, check the source files that whether we can build this file for target platform by checking file name and build tags. Signed-off-by: Bin Lu <bin.lu@arm.com>
2019-10-16Reorder BUILD license and load functions in gvisor.Kevin Krakauer
PiperOrigin-RevId: 275139066
2019-09-18Move the component into the repository structure.Adin Scannell
The RELEASE file must be at the top-level for the signed repository to work correctly. PiperOrigin-RevId: 269897109
2019-09-12Remove go_test from go_stateify and go_marshalMichael Pratt
They are no-ops, so the standard rule works fine. PiperOrigin-RevId: 268776264
2019-09-12Merge pull request #843 from nlacasse:versiongVisor bot
PiperOrigin-RevId: 268772451
2019-09-12Update repository directory structure.Adin Scannell
Currently it will not work with apt out of the box, as we require the dists/ prefix, along with a distribution name. This tweaks the overall structure to allow for the same URL prefix to be used for all repositories, and enables multiple architectures. Fixes #852 PiperOrigin-RevId: 268756104
2019-09-10Fix `runsc --version` and add a test.Nicolas Lacasse
We need to include the `--stamp` flag in `tools/workspace_status.sh` for the version to be picked up by the linker. Not sure why. Also changes the VERSION string to STABLE_VERSION, which will cause the program to be re-linked if the string changes. Fixes #830
2019-09-10Fix minor Kokoro issues.Adin Scannell
A recent Kokoro change pointed to go_tests.cfg (in line with the other configurations), which unfortunately broke the presubmits. This change also enabled the KVM tests, which were still using a remote execution strategy. This fixes both of these issues and allows presubmits to pass. One additional test was caught with this case, which seems to have been broken. It's unclear why this was not being caught. PiperOrigin-RevId: 268166291
2019-09-09go_marshal: Implement automatic generation of ABI marshalling code.Rahat Mahmood
This CL implements go_marshal, a code generation utility for automatically serializing and deserializing ABI structs. The go_marshal tool automatically generates implementations of the new marshal interface. Unlike binary.Marshal/Unmarshal, the generated interface implementations use no runtime reflection, and translates to a single memcpy for most structs. See go_marshal/README.md for details. PiperOrigin-RevId: 268065475
2019-09-06Fix repository build scriptsAdin Scannell
This has the following fixes: * Packages are passed to the tools/make_repository.sh command. * All matching tags are built, for commits with multiple. * The binary path is generated by the build command. * Output from signing the repository is supressed. * Allow a release author. Change-Id: I2d08954ba76e35612f352be99d5bb99080f80892
2019-09-03Impose order on test scripts.Adin Scannell
The simple test script has gotten out of control. Shard this script into different pieces and attempt to impose order on overall test structure. This change helps lay some of the foundations for future improvements. * The runsc/test directories are moved into just test/. * The runsc/test/testutil package is split into logical pieces. * The scripts/ directory contains new top-level targets. * Each test is now responsible for building targets it requires. * The install functionality is moved into `runsc` itself for simplicity. * The existing kokoro run_tests.sh file now just calls all (can be split). After this change is merged, I will create multiple distinct workflows for Kokoro, one for each of the scripts currently targeted by `run_tests.sh` today, which should dramatically reduce the time-to-run for the Kokoro tests, and provides a better foundation for further improvements to the infrastructure. PiperOrigin-RevId: 267081397
2019-08-27kokoro: Add scripts to rebuild images.Adin Scannell
These scripts generated the following images: gvisor-kokoro-testing/image-a53bac71541a209e (ubuntu 18.04) gvisor-kokoro-testing/image-f5b20c5fbd23f448 (ubuntu 16.04) Any modifications to these scripts should generate new images. PiperOrigin-RevId: 265843929

PiperOrigin-RevId: 265606322
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

2019-06-25gvisor: lockless read access for task credentialsAndrei Vagin
Credentials are immutable and even before these changes we could read them without locks, but we needed to take a task lock to get a credential object from a task object. It is possible to avoid this lock, if we will guarantee that a credential object will not be changed after setting it on a task. PiperOrigin-RevId: 254989492
