einat-ebpf for openwrt

What is this

Build scripts for Openwrt to create package einat-ebpf

Requirements

1. Openwrt with Reduce debugging information set to N

2. Openwrt kernel module kmod-sched-bpf

Usage:

1. Clone this repo

   git clone https://github.com/arenekosreal/einat-ebpf \
    /path/to/openwrt/package/openwrt-packages/einat-ebpf
   

Don't forget to replace /path/to/openwrt with real path of your openwrt source code.

2. Configuration

   Run make menuconfig to open openwrt configuration, do those changes:

   1. Global build settings -> Kernel build options -> Reduce debugging information set to N

   2. Advanced configuration options (for developers) -> BPF toolchain set to Use host LLVM toolchain

      Openwrt use clang 15, which is not new enough. clang 17 on Arch Linux is tested and build successfully.

   3. You can find einat-ebpf at Network -> Routing and Rediretion after the steps above are done correctly.

      By default the ipv6 feature is not enabled, you can enable it in the menu.

3. Build

   Run make package/openwrt-packages/einat-ebpf/compile to build ipk file. You will find output at bin/packages/$TARGET_ARCH/packages
