2021-04-05Update gofer dentry permissions only when needed.Ayush Ranjan
Without this change, we ask the gofer server to update the permissions whenever the UID, GID or size is updated via SetStat. Consequently, we don not generate inotify events when the permissions actually change due to SGID bit getting cleared. With this change, we will update the permissions only when needed and generate inotify events. PiperOrigin-RevId: 366946842

2021-04-05Fix listen backlog handling to be in parity with LinuxMithun Iyer
- Change the accept queue full condition for a listening endpoint to only honor completed (and delivered) connections. - Use syncookies if the number of incomplete connections is beyond listen backlog. This also cleans up the SynThreshold option code as that is no longer used with this change. - Added a new stack option to unconditionally generate syncookies. Similar to sysctl -w net.ipv4.tcp_syncookies=2 on Linux. - Enable keeping of incomplete connections beyond listen backlog. - Drop incoming SYNs only if the accept queue is filled up. - Drop incoming ACKs that complete handshakes when accept queue is full - Enable the stack to accept one more connection than programmed by listen backlog. - Handle backlog argument being zero, negative for listen, as Linux. - Add syscall and packetimpact tests to reflect the changes above. - Remove TCPConnectBacklog test which is polling for completed connections on the client side which is not reflective of whether the accept queue is filled up by the test. The modified syscall test in this CL addresses testing of connecting sockets. Fixes #3153 PiperOrigin-RevId: 366935921

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
2021-03-26arm64 ring0: don't use inner-sharable to invalidate tlbRobin Luk
It is enough to invalidate the tlb of local vcpu in switch(). TLBI with inner-sharable will invalidate the tlb in other vcpu. Arm64 hardware supports at least 256 pcid, so I think it's ok to set the length of pcid pool to 128. Signed-off-by: Robin Luk <lubin.lu@antgroup.com>

On Linux these are meant to be equivalent to POLLIN/POLLOUT. Rather than hack these on in sys_poll etc it felt cleaner to just cleanup the call sites to notify for both events. This is what linux does as well. Fixes #5544 PiperOrigin-RevId: 364859977
