Beeper: Application-Layer Parsing in eBPF

About

Beeper is a Rust library that parses application-layer protocols (HTTP/1.1 and HTTP/2, with RESP2 in progress) directly in the Linux kernel through eBPF. It builds an Aho-Corasick-like DFA in user space so the parsing fits eBPF limits, which lets programs monitor, redirect or answer traffic from the kernel. A companion project uses it to serve static assets from the kernel, raising HTTP server throughput by up to 4.5x.
