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.

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

2020-07-23Convert go_generics tests to starlark.Adin Scannell
For some reason these tests were broken when run via the bazel docker container. The mechanism used was a bit crazy (self-extracting bundle), so convert them to use straight-forward starlark rules. This has the added advantaged that they are now independent tests.

2020-05-20Implement gap tracking in the segment set.Reapor-Yurnero
This change was derived from a change by: Reapor-Yurnero <reapor.yurnero@gmail.com> And has been modified by: Adin Scannell <ascannell@google.com> (The original change author is preserved for the commit.) This change implements gap tracking in the segment set by adding additional information in each node, and using that information to speed up gap finding from a linear scan to a O(log(n)) walk of the tree. This gap tracking is optional, and will default to off except for segment instances that set gapTracking equal to 1 in their const lists. PiperOrigin-RevId: 312621607

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

2018-12-28Extract go_merge into its own packageTamir Duberstein
This change is needed to support building gvisor for Fuchsia, which uses Chromium's GN build system; at the time of writing, Fuchsia's Go support does not include explicit enumeration of files, assuming instead that Go binaries are always built from all Go source files in a given package. Rather than extending Fuchsia's Go support, it is easier simply to extract a separate package here. PiperOrigin-RevId: 227133402 Change-Id: I1c64fff286d9c014b4bd1183b76023b35b60c720
