IPv4 Address Conflict Detection

The n-acd project implements the IPv4 Address Conflict Detection standard as defined in RFC-5227. The state machine is implemented in a shared library and provides a stable ISO-C11 API. The implementation is linux-only and relies heavily on the API behavior of recent linux kernel releases.

Requirements

The requirements for this project are:

• Linux kernel >= 3.19
• libc (e.g., glibc >= 2.16)

At build-time, the following software is required:

• meson >= 0.41
• pkg-config >= 0.29

Build

The meson build-system is used for this project. Contact upstream documentation for detailed help. In most situations the following commands are sufficient to build and install from source:

mkdir build
cd build
meson setup ..
ninja
meson test
ninja install

The following configuration options are available:

• ebpf: This boolean controls whether ebpf features are used to improve the package filtering performance. If disabled, classic bpf will be used. This feature requires a rather recent kernel (>=3.19). Default is: true
