2021-03-30Fix panic when overriding /dev files with VFS2Fabricio Voznika
VFS1 skips over mounts that overrides files in /dev because the list of files is hardcoded. This is not needed for VFS2 and a recent change lifted this restriction. However, parts of the code were still skipping /dev mounts even in VFS2, causing the loader to panic when it ran short of FDs to connect to the gofer. PiperOrigin-RevId: 365858436

2021-03-29[perf] Reduce contention in ptrace.threadPool.lookupOrCreate().Ayush Ranjan
lookupOrCreate is called from subprocess.switchToApp() and subprocess.syscall(). lookupOrCreate() looks for a thread already created for the current TID. If a thread exists (common case), it returns immediately. Otherwise it creates a new one. This change switches to using a sync.RWMutex. The initial thread existence lookup is now done only with the read lock. So multiple successful lookups can occur concurrently. Only when a new thread is created will it acquire the lock for writing and update the map (which is not the common case). Discovered in mutex profiles from the various ptrace benchmarks. Example: https://gvisor.dev/profile/gvisor-buildkite/fd14bfad-b30f-44dc-859b-80ebac50beb4/843827db-da50-4dc9-a2ea-ecf734dde2d5/tmp/profile/ptrace/BenchmarkFio/operation.write/blockSize.4K/filesystem.tmpfs/benchmarks/fio/mutex.pprof/flamegraph PiperOrigin-RevId: 365612094

2021-03-24Add POLLRDNORM/POLLWRNORM support.Bhasker Hariharan
