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

PiperOrigin-RevId: 388985968
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
