Linux Kernel eBPF CO-RE

The respository has the following directory structure:

• artifacts: directory that will have the eBPF programs when the compilation process ends.
• includes: headers used to compile eBPF.plugin.
• kernel-collector: this is a submodule'd fork of netdata/libbpf.
• libbpf: this is a submodule'd fork of netdata/libbpf which is itself a fork of the official libbpf package, the user-space side of eBPF system calls.

To compile the eBPF CO-RE, it will be necessary to have the following packages:

• libelf headers
• LLVM/Clang; this is because GCC prior to 10.0 cannot compile eBPF code.
• bpftool: used to generate source codes.

libbpf directory is included as a git submodule and it is necessary to fetch contents with the git command below:

git submodule update --init --recursive
