2021-08-05Skip mmap test cases if underlying FS doesn't support maps.Rahat Mahmood
For file-based mmap tests, the underlying file system may not support mmaps depending on the sandbox configuration. This is case when caching is disabled for goferfs. PiperOrigin-RevId: 389052722
2021-08-05Bump gVisor build tags to go1.19Michael Pratt
Go's dev.typeparams branch already claims to be Go 1.18, so our !go1.18 build tags breaking testing gVisor with that branch. Normally I would not want to bump the build tags this early, but I plan to extend checklinkname to check the assumptions in these files and remove the build tags ASAP. So we just go ahead and bump the tags until then to unblock testing. PiperOrigin-RevId: 389037239

2021-08-04Reduce overhead of AlignedAtomic typesAndrei Vagin
AlignedAtomicUint64 is 15 bytes and it takes 16 bytes in structures. On 32-bit systems, variables and structure fields is guaranteed to be 32-bit aligned and this means that we need only 12 bytes to find 8 contiguous bytes.

This change will allow us to remove the default link in a packetimpact test so we can reduce indeterministic behaviors as required in https://fxbug.dev/78430. This will also help with testing #1388. Updates #578, #1388. PiperOrigin-RevId: 387896847

2021-07-30checklinkname: rudimentary type-checking of linkname directivesMichael Pratt
This CL introduces a 'checklinkname' analyzer, which provides rudimentary type-checking that verifies that function signatures on the local and remote sides of //go:linkname directives match expected values. If the Go standard library changes the definitions of any of these function, checklinkname will flag the change as a finding, providing an error informing the gVisor team to adapt to the upstream changes. This allows us to eliminate the majority of gVisor's forward-looking negative build tags, as we can catch mismatches in testing [1]. The remaining forward-looking negative build tags are covering shared struct definitions, which I hope to add to checklinkname in a future CL. [1] Of course, semantics/requirements can change without the signature changing, so we still must be careful, but this covers the common case. PiperOrigin-RevId: 387873847

2021-07-27Use go:build directives in generated files.Jamie Liu
Build constraints are now inferred from go:build directives rather than +build directives. +build directives are still emitted in generated files as required in Go 1.16 and earlier. Note that go/build/constraint was added in Go 1.16, so gVisor now requires Go 1.16. PiperOrigin-RevId: 387240779

2021-07-26Fix per-analyzer overrides of default-disabled groupsMichael Pratt
Currently behavior of config groups with `default: false` is buggy. The intention is that adding an empty suppression section for that group to a specific analyzer config should enable reporting for that analyzer. i.e., ``` groups: - name: foo regex: "^foo/" default: false global: ... analyzers: asmdecl: foo: # Enabled. ``` This should enable the foo group only for asmdecl. Unfortunately, today the actual behavior depends on the contents of the `global:` section. If `global:` contains an entry for foo, then it will work as described. If `global:` does _not_ contain an entry for foo, then the group default (disabled) always applies and the individual analyzer options have no effect. The cause of this is confusion in `AnalyzerConfig.shouldReport`, which doesn't distinguish between explicit suppression via a global suppression/exclude and simply having no configuration at all. Make this more explicit, so that the no configuration case can continue to per-analyzer configuration before falling back to the group default. The last test case in the added test fails without this change. This re-enables several opted-in analyzers for external dependencies, which have gained a few more false positives to suppress.
