Jiyong Park 093f11b496 vsock: each transport cycles only on its own sockets ... [ Upstream commit 8e6ed96376 ] When iterating over sockets using vsock_for_each_connected_socket, make sure that a transport filters out sockets that don't belong to the transport. There actually was an issue caused by this; in a nested VM configuration, destroying the nested VM (which often involves the closing of /dev/vhost-vsock if there was h2g connections to the nested VM) kills not only the h2g connections, but also all existing g2h connections to the (outmost) host which are totally unrelated. Tested: Executed the following steps on Cuttlefish (Android running on a VM) [1]: (1) Enter into an `adb shell` session - to have a g2h connection inside the VM, (2) open and then close /dev/vhost-vsock by `exec 3< /dev/vhost-vsock && exec 3<&-`, (3) observe that the adb session is not reset.
