Summary of changes: - Fix some new sparse issues. - Remove some unneeded casts for VMCI. - add more __user annotations for VMCI. - Remove kernel version-specific bits from vSockets. * * * In an effort to improve the out-of-the-box experience with Linux kernels for VMware users, VMware is working on readying the Virtual Machine Communication Interface (vmw_vmci) and VMCI Sockets (VSOCK) (vmw_vsock) kernel modules for inclusion in the Linux kernel. The purpose of this post is to acquire feedback on the vmw_vsock kernel module. The vmw_vmci kernel module has been presented in an early post. * * * VMCI Sockets allows virtual machines to communicate with host kernel modules and the VMware hypervisors. VMCI Sockets kernel module has dependency on VMCI kernel module. User level applications both in a virtual machine and on the host can use vmw_vmci through VMCI 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. Today, VMCI and VMCI Sockets are used by the VMware shared folders (HGFS) and 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 VMCI 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 VMCI Sockets are similar to other socket types, like Berkeley UNIX socket interface. The VMCI sockets module supports both connection-oriented stream sockets like TCP, and connectionless datagram sockets like UDP. The VSOCK 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 VMCI and in particular VMCI Sockets, please refer to the VMCI Socket Programming Guide available at https://www.vmware.com/support/developer/vmci-sdk/. --- George Zhang (6): VSOCK: vsock protocol implementation.
