sdsen / bpfd

a prototype networking bpf loader

bpfd

A work in progress implementation of the xdp_multiprog protocol in Rust, using Aya. It differs from the implementation in libxdp as we have chosen to implement a daemon instead.

• bpfd is the daemon
• bpfctl is the client program

There is a gRPC API that connects the two

Requirements

• Rust Stable & Rust Nightly
• My fork of bpf-linker
• protoc
• LLVM 11 or later

Building

$ cargo xtask build-ebpf --release
$ cargo build

Usage

Load the sample XDP Program:

$ cargo build
$ sudo ./target/debug/bpfd&
$ ./target/debug/bpfctl load ./target/bpfel-unknown-none/release/xdp-pass -p xdp -i wlp2s0 --priority 50 -s "pass"
