[PATCH 0/1] VM Sockets for Linux upstreaming

[acking]

From: Andy King <acking@xxxxxxxxxx>

** Introduce VM Sockets ***

In an effort to improve the out-of-the-box experience with Linux kernels for
VMware users, VMware is working on readying the VM Sockets (VSOCK, formerly
VMCI Sockets) (vmw_vsock) kernel module for inclusion in the Linux kernel. The
purpose of this post is to acquire feedback on the vmw_vsock kernel module.

Unlike previous submissions, where the new socket family was entirely reliant
on VMware's VMCI PCI device (and thus VMware's hypervisor), VM Sockets is now
_mostly_ separated out into two parts:

o Core socket code, which is transport-neutral and invokes transport
  callbacks to communicate with the hypervisor.
o A VMCI transport, which communicates over VMCI with the VMware hypervisor.

This should provide a path to introducing additional transports, for example
virtio, with the ultimate goal being to make this new socket family
hypervisor-neutral.
