Hi Sudip,
suricata FTBFS with libbpf 1.0.0 (available in experimental). This is the first error from the build log:util-ebpf.c: In function 'EBPFLoadFile': util-ebpf.c:375:17: error: implicit declaration of function 'bpf_program__set_socket_filter'; did you mean 'bpf_program__set_log_level'? [-Werror=implicit-function-declaration] 375 | bpf_program__set_socket_filter(bpfprog); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | bpf_program__set_log_level util-ebpf.c:377:17: error: implicit declaration of function 'bpf_program__set_xdp'; did you mean 'bpf_program__set_type'? [-Werror=implicit-function-declaration] 377 | bpf_program__set_xdp(bpfprog); | ^~~~~~~~~~~~~~~~~~~~ | bpf_program__set_type
Thanks for reporting this. This issue is likely due to libbpf 1.0.0 removing previously deprecated functions, which are still used in Suricata's eBPF code. I have found a backwards-compatible fix and am currently in contact with upstream.
Best regards Sascha
