2020-11-19Require sync.Mutex to lock and unlock from the same goroutineMichael Pratt
We would like to track locks ordering to detect ordering violations. Detecting violations is much simpler if mutexes must be unlocked by the same goroutine that locked them. Thus, as a first step to tracking lock ordering, add this lock/unlock requirement to gVisor's sync.Mutex. This is more strict than the Go standard library's sync.Mutex, but initial testing indicates only a single lock that is used across goroutines. The new sync.CrossGoroutineMutex relaxes the requirement (but will not provide lock order checking). Due to the additional overhead, enforcement is only enabled with the "checklocks" build tag. Build with this tag using: bazel build --define=gotags=checklocks ... From my spot-checking, this has no changed inlining properties when disabled. Updates #4804 PiperOrigin-RevId: 343370200
