Suricata

When running Suricata with (at least) bypass filters of eBPF (bypass_filter.bpf) or XDP (xdp_filter.bpf), libbpf library outputs warnings that certain libbpf API calls are deprecated and should be updated.
As of now, this does not affect the functionality of the examples and only outputs multiple warning lines. Warnings are shown during Suricata initialization.
Running kernel 4.18.
