Stefano Garzarella says: ==================== vsock: add local transport support v2: - style fixes [Dave] - removed RCU sync and changed 'the_vsock_loopback' in a global static variable [Stefan] - use G2H transport when local transport is not loaded and remote cid is VMADDR_CID_LOCAL [Stefan] - rebased on net-next v1: https://patchwork.kernel.org/cover/11251735/ This series introduces a new transport (vsock_loopback) to handle local communication. This could be useful to test vsock core itself and to allow developers to test their applications without launching a VM. Before this series, vmci and virtio transports allowed this behavior, but only in the guest. We are moving the loopback handling in a new transport, because it might be useful to provide this feature also in the host or when no H2G/G2H transports (hyperv, virtio, vmci) are loaded. The user can use the loopback with the new VMADDR_CID_LOCAL (that replaces VMADDR_CID_RESERVED) in any condition. Otherwise, if the G2H transport is loaded, it can also use the guest local CID as previously supported by vmci and virtio transports. If G2H transport is not loaded, the user can also use VMADDR_CID_HOST for local communication. Patch 1 is a cleanup to build virtio_transport_common without virtio Patch 2 adds the new VMADDR_CID_LOCAL, replacing VMADDR_CID_RESERVED Patch 3 adds a new feature flag to register a loopback transport Patch 4 adds the new vsock_loopback transport based on the loopback implementation of virtio_transport Patch 5 implements the logic to use the local transport for loopback communication Patch 6 removes the loopback from virtio_transport ==================== Signed-off-by: David S.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
