For a significant period, bpfilter wasn't more than an empty usermode helper and an abandoned patch series. However, it has recently undergone active development as a userspace daemon, which can be found on GitHub at https://github.com/facebook/bpfilter. This daemon now offers userspace services a swift and user-friendly interface to generate packet-filtering BPF programs dynamically. This discussion aims to provide further insights into bpfilter, including its current capabilities, performance, and ongoing development efforts.
