similar to: [PATCH net 0/2] vsock: don't allow half-closed socket in the host transports

This series adds the multi-transports support to vsock, following this proposal: https://www.spinics.net/lists/netdev/msg575792.html With the multi-transports support, we can use VSOCK with nested VMs (using also different hypervisors) loading both guest->host and host->guest transports at the same time. Before this series, vmci-transport supported this behavior but only using VMware

Most of the patches are reviewed by Dexuan, Stefan, and Jorgen. The following patches need reviews: - [11/15] vsock: add multi-transports support - [12/15] vsock/vmci: register vmci_transport only when VMCI guest/host are active - [15/15] vhost/vsock: refuse CID assigned to the guest->host transport RFC: https://patchwork.ozlabs.org/cover/1168442/ v1:

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.

Hi, now that we have multi-transport upstream, I started to take a look to support network namespace (netns) in vsock. As we partially discussed in the multi-transport proposal [1], it could be nice to support network namespace in vsock to reach the following goals: - isolate host applications from guest applications using the same ports with CID_ANY - assign the same CID of VMs running in

This series is based on v4.7. This RFC is the implementation for the new VIRTIO Socket device. It is developed in parallel with the VIRTIO device specification and proves the design. Once the specification has been accepted I will send a non-RFC version of this patch series. v6: * Add VHOST_VSOCK_SET_RUNNING ioctl to start/stop vhost cleanly * Add graceful shutdown to avoid port reuse while
