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: This week most of the time was spent figuring about how the XDP hook will be implemented using pfil framework and a basic design for implementation was created. Currently I am on: - XDP hook - This week's goal is to create a basic XDP hook. Project GSoC Wiki: https://wiki.freebsd.org/SummerOfCodeIdeas#eBPF_XDP_Hooks Github Repo for the code: https://github.com/rysto32/freebsd/tree/ebpf-import Github repo including the changes made so far: https://github.com/Ankurk99/freebsd/tree/ebpf-import Thank you for reading.
