Recent debugging on vhost net zerocopy shows the need of tracepoints. So to help in vhost{net} debugging and performance analyzing, the following series adding basic tracepoints to vhost. Operations of both vhost and vhost_net were traced in current implementation. A top-like satistics displaying script were introduced to help the troubleshooting: vhost statistics vhost_virtio_update_used_idx

This fixes various problems that cropped up with the vdso patches. - Patch 1 fixes an information leak to userspace. - Patches 2 and 3 fix the kernel build on gold. - Patches 4 and 5 fix Xen (I hope). - Patch 6 (optional) adds a trace event to vsyscall emulation. It will make it easier to handle performance regression reports :) [1]

This series is based on Michael Tsirkin's vhost branch (v4.5-rc6). I'm about to process Claudio Imbrenda's locking fixes for virtio-vsock but first I want to share the latest version of the code. Several people are playing with vsock now so sharing the latest code should avoid duplicate work. v5: * Transport reset event for live migration support * Reorder virtqueues, drop unused

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
