Hi all, Project: Implement eBPF XDP for FreeBSD by extending VirtIO ethernet driver if_vtnet The goal of this project is to extend an existing FreeBSD network driver,VirtIO if_vtnet to be able to call into an eBPF program when processing a newly received packet. The driver will perform the basic actions of XDP like PASS and DROP the packet as specified by the program. The project will also implement new map type and other eBPF helper functions.The aim of this project is to add new probe sites into the kernel that will call eBPF functions. Mentor: Ryan Stone <rstone@> and Hiroki Sato <hrs@> Progress made this week: - create hooks and link them to the pfil head when the eBPF XDP probe is activated - manage to list the XDP probes Currently: - This week's goal is to create a xdp_rx function which will pass the received packets to the ebpf program where the packets can be further processed.
