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.

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

2020-02-11Ensure fsimpl/gofer.dentryPlatformFile.hostFileMapper is initialized.gVisor bot
Fixes #1812. (The more direct cause of the deadlock is panic unsafety because the historically high cost of defer means that we avoid it in hot paths, including much of MM; defer is much cheaper as of Go 1.14, but still a measurable overhead.) PiperOrigin-RevId: 294560316

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

The slaveInodeOperations is currently copying the object when truncate is called (which is a no-op). This may result in a (unconsequential) data race when being modified concurrently. PiperOrigin-RevId: 294484276
