2021-03-03[op] Replace syscall package usage with golang.org/x/sys/unix in pkg/.Ayush Ranjan
The syscall package has been deprecated in favor of golang.org/x/sys. Note that syscall is still used in the following places: - pkg/sentry/socket/hostinet/stack.go: some netlink related functionalities are not yet available in golang.org/x/sys. - syscall.Stat_t is still used in some places because os.FileInfo.Sys() still returns it and not unix.Stat_t.

2020-01-09New sync package.Ian Gudger
* Rename syncutil to sync. * Add aliases to sync types. * Replace existing usage of standard library sync package. This will make it easier to swap out synchronization primitives. For example, this will allow us to use primitives from github.com/sasha-s/go-deadlock to check for lock ordering violations. Updates #1472 PiperOrigin-RevId: 289033387

2018-12-17Implement mlock(), kind of.Jamie Liu
Currently mlock() and friends do nothing whatsoever. However, mlocking is directly application-visible in a number of ways; for example, madvise(MADV_DONTNEED) and msync(MS_INVALIDATE) both fail on mlocked regions. We handle this inconsistently: MADV_DONTNEED is too important to not work, but MS_INVALIDATE is rejected. Change MM to track mlocked regions in a manner consistent with Linux. It still will not actually pin pages into host physical memory, but: - mlock() will now cause sentry memory management to precommit mlocked pages. - MADV_DONTNEED and MS_INVALIDATE will interact with mlocked pages as described above.
