2019-12-12vsock: add vsock_loopback transportStefano Garzarella1-0/+12
This patch adds a new vsock_loopback transport to handle local communication. This transport is based on the loopback implementation of virtio_transport, so it uses the virtio_transport_common APIs to interface with the vsock core.

2017-10-06VSOCK: add sock_diag interfaceStefan Hajnoczi1-0/+10
This patch adds the sock_diag interface for querying sockets from userspace. Tools like ss(8) and netstat(8) can use this interface to list open sockets. The userspace ABI is defined in <linux/vm_sockets_diag.h> and includes netlink request and response structs. The request can query sockets based on their sk_state (e.g. listening sockets only) and the response contains socket information fields including the local/remote addresses, inode number, etc. This patch does not dump VMCI pending sockets because I have only tested the virtio transport, which does not use pending sockets. Support can be added later by extending vsock_diag_dump() if needed by VMCI users. Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-08-29hv_sock: implements Hyper-V transport for Virtual Sockets (AF_VSOCK)Dexuan Cui1-0/+12
Hyper-V Sockets (hv_sock) supplies a byte-stream based communication mechanism between the host and the guest. It uses VMBus ringbuffer as the transportation layer. With hv_sock, applications between the host (Windows 10, Windows Server 2016 or newer) and the guest can talk with each other using the traditional socket APIs. More info about Hyper-V Sockets is available here: "Make your own integration services": https://docs.microsoft.com/en-us/virtualization/hyper-v-on-windows/user-guide/make-integration-service The patch implements the necessary support in Linux guest by introducing a new vsock transport for AF_VSOCK.

2013-02-11VSOCK: Introduce VM SocketsAndy King1-0/+28
VM Sockets allows communication between virtual machines and the hypervisor. User level applications both in a virtual machine and on the host can use the VM Sockets API, which facilitates fast and efficient communication between guest virtual machines and their host. A socket address family, designed to be compatible with UDP and TCP at the interface level, is provided. Today, VM Sockets is used by various VMware Tools components inside the guest for zero-config, network-less access to VMware host services. In addition to this, VMware's users are using VM Sockets for various applications, where network access of the virtual machine is restricted or non-existent. Examples of this are VMs communicating with device proxies for proprietary hardware running as host applications and automated testing of applications running within virtual machines. The VMware VM Sockets are similar to other socket types, like Berkeley UNIX socket interface. The VM Sockets module supports both connection-oriented stream sockets like TCP, and connectionless datagram sockets like UDP. The VM Sockets protocol family is defined as "AF_VSOCK" and the socket operations split for SOCK_DGRAM and SOCK_STREAM. For additional information about the use of VM Sockets, please refer to the VM Sockets Programming Guide available at: https://www.vmware.com/support/developer/vmci-sdk/ Signed-off-by: George Zhang <georgezhang@vmware.com> Signed-off-by: Dmitry Torokhov <dtor@vmware.com> Signed-off-by: Andy king <acking@vmware.com> Signed-off-by: David S.
