Joe and I have been experimenting with BPF and its application for OVS. This patch shows our attempt to implement ovs actions using eBPF.
The kernel changes are against the 'net-next'. The corresponding user space changes will be post next. This patch set implements an BPF action, that has the same interface as current OVS output action. Instead of sending out a packet, it only generates a kernel message. This feature is neither complete nor useful as is. We are mostly interested in comments on: The infrastructure changes to support and running BPF functions, and suggestions on extensions beyond those patches.
