This works in the same way as patch from Bobby Eshleman: commit c43170b7e157 ("vsock: return errors other than -ENOMEM to socket"), but for receive calls. VMCI transport is also updated (both tx and rx SOCK_STREAM callbacks), because it returns VMCI specific error code to af_vsock.c (like VMCI_ERROR_*). At the same time, virtio and Hyper-V transports are using general error codes, so there is no need to update them. vsock_test suite is also updated.
