# # Vsock protocol # config VSOCKETS tristate "Virtual Socket protocol" help Virtual Socket Protocol is a socket protocol similar to TCP/IP allowing communication between Virtual Machines and hypervisor or host. You should also select one or more hypervisor-specific transports below. To compile this driver as a module, choose M here: the module will be called vsock. If unsure, say N. config VMWARE_VMCI_VSOCKETS tristate "VMware VMCI transport for Virtual Sockets" depends on VSOCKETS && VMWARE_VMCI help This module implements a VMCI transport for Virtual Sockets. Enable this transport if your Virtual Machine runs on a VMware hypervisor. To compile this driver as a module, choose M here: the module will be called vmw_vsock_vmci_transport. If unsure, say N. config VIRTIO_VSOCKETS tristate "virtio transport for Virtual Sockets" depends on VSOCKETS && VIRTIO select VIRTIO_VSOCKETS_COMMON help This module implements a virtio transport for Virtual Sockets. Enable this transport if your Virtual Machine host supports Virtual Sockets over virtio. To compile this driver as a module, choose M here: the module will be called vmw_vsock_virtio_transport. If unsure, say N. config VIRTIO_VSOCKETS_COMMON tristate help This option is selected by any driver which needs to access the virtio_vsock.

PCI/MSI: Don't apply affinity if there aren't enough vectors left
Bart reported a problem wіth an out of bounds access in the low-level IRQ affinity code, which we root caused to the qla2xxx driver assigning all its MSI-X vectors to the pre and post vectors, and not having any left for the actually spread IRQs. Fix this issue by not asking for affinity assignment when there are no vectors to assign left.
