bpfstats

Build

To build the program just run make. In this project it has been used bpftools and libbpf. vmlinux.h file contains every kernel function and type for a specific version, so this file should be generated from the current version of the Linux kernel.

Known problem

File bpf_struct.h is required because libbpf set_attach_target function doesn't permit to attach a bpf program to a kernel function dynamicaly with fentry/fexit. So it was necessary to change the vmlinux_btf variable of a bpf program, in order to do that was required to define the bpf_program and bpf_object structure like they're defined in libbpf.c.
