search for: vsock_core_get_transport

Since now the 'struct vsock_sock' object contains a pointer to the transport, this patch adds a parameter to the vsock_core_get_transport() to return the right transport assigned to the socket. This patch modifies also the virtio_transport_get_ops(), that uses the vsock_core_get_transport(), adding the 'struct vsock_sock *' parameter.

Currently, if a connect call fails on a signal or timeout (e.g., guest is still in the process of starting up), we'll just return to caller and leave the connect packet queued and they are sent even though the connection is considered a failure, which can confuse applications with unwanted false connect attempt. The patchset enables vsock (both host and guest) to cancel queued packets when a
