Hi Stefan, I'm thinking about dividing this test into single applications, one for each test, do you think it makes sense? Or is it just a useless complication?

The vsock_diag.ko module already has a test suite but the core AF_VSOCK functionality has no tests. This patch series adds several test cases that exercise AF_VSOCK SOCK_STREAM socket semantics (send/recv, connect/accept, half-closed connections, simultaneous connections). Stefan: Do you think we should have a single application or is better to split it in single tests (e.g.

vsock_insert_unbound() was called only when 'sock' parameter of __vsock_create() was not null. This only happened when __vsock_create() was called by vsock_create(). In order to simplify the multi-transports support, this patch moves vsock_insert_unbound() at the end of vsock_create().

virtio_transport and vmci_transport handle the buffer_size sockopts in a very similar way. In order to support multiple transports, this patch moves this handling in the core to allow the user to change the options also if the socket is not yet assigned to any transport. This patch also adds the '.notify_buffer_size' callback in the 'struct virtio_transport' in order to inform

VMCI transport provides both g2h and h2g behaviors in a single transport. We are able to set (or not) the g2h behavior, detecting if we are in a VMware guest (or not), but the h2g feature is always set. This prevents to load other h2g transports while we are in a VMware guest. This patch adds a new 'transport_hg' to handle this case, reducing the priority of transports that provide both
