Hi all, 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

Now we send VMADDR_CID_RESERVED (LOCAL) to the guest when there is no transport_local loaded? If this is correct, is there a justification for this change? It seems safest to retain existing behavior. -------------- next part -------------- A no...

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.
