We are implementing a test suite for the VSOCK sockets and we discovered that vmci_transport never allowed half-closed socket on the host side. As Jorgen explained [1] this is due to the implementation of VMCI.

The virtio-vsock device specification is not finalized yet. Michael Tsirkin voiced concerned about merging this code when the hardware interface (and possibly the userspace interface) could still change. Please revert for now. I am working to finalize the virtio-vsock device specification and at that point the interfaces will be stable. Stefan Hajnoczi (6): Revert "VSOCK: fix
