2021-06-28netstack: deflake TestSynRcvdBadSeqNumberKevin Krakauer
There was a race wherein Accept() could fail, then the handshake would complete, and then a waiter would be created to listen for the handshake. In such cases, no notification was ever sent and the test timed out. PiperOrigin-RevId: 381913041

2021-06-25Remove sndQueue as its pointless now.Bhasker Hariharan
sndQueue made sense when the worker goroutine and the syscall context held different locks. Now both lock the endpoint lock before doing anything which means adding to sndQueue is pointless as we move it to writeList immediately after that in endpoint.Write() by calling e.drainSendQueue.

2021-06-24Incrementally update checksum when NAT-ingGhanan Gowripalan
...instead of calculating a fresh checksum to avoid re-calcalculating a checksum on unchanged bytes. Fixes #5340. PiperOrigin-RevId: 381403888
2021-06-24Refactor default router state to off-link route stateGhanan Gowripalan
This change prepares for a later change which supports the NDP Route Information option to discover more-specific routes, as per RFC 4191. The newly introduced off-link route state will be used to hold both the state for default routers (which is a default (off-link) route through the router, and more-specific routes (which are routes through some router to some destination subnet more specific than the IPv6 empty subnet). Updates #6172. PiperOrigin-RevId: 381403761

2021-06-23Do not attempt to kill stopped exec processesNoah Fontes
While #6204 addressed the stopped state for handling signals in the main process, it did not update exec processes in the same way. This change mirrors that adjustment for exec processes.
2021-06-23Ensure shim propagates errors over gRPC correctlyNoah Fontes
This change wraps containerd's errdefs.ToGRPC function with one that understands Go 1.13-style error wrapping style, which is used pervasively throughout the shim. With this change, errors that have been marked with, e.g., `errdefs.ErrNotFound`, will be correctly propagated back to the containerd server.

2021-06-22`socket_inet_loopback`: Split off tests that need isolation in their own file.Etienne Perot
This allows these tests, which can cause flakiness when run in the same network namespace as the other `socket_inet_loopback` tests, to run as separate tests in their own environment. It also means that all of the shards of those tests can be more isolated from each other as well. PiperOrigin-RevId: 380930198

2021-06-22runsc: don't kill sandbox, let it stop properlyAndrei Vagin
The typical sequence of calls to start a container looks like this ct, err := container.New(conf, containerArgs) defer ct.Destroy() ct.Start(conf) ws, err := ct.Wait() For the root container, ct.Destroy() kills the sandbox process. This doesn't look like a right wait to stop it. For example, all ongoing rpc calls are aborted in this case. If everything is going alright, we can just wait and it will exit itself.
