From b85fab0e67b162014cd328cb4e2a8e8ae382cb8a Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Wed, 25 Apr 2018 19:41:06 +0200 Subject: bpf: Add gpl_compatible flag to struct bpf_prog_info Adding gpl_compatible flag to struct bpf_prog_info so it can be dumped via bpf_prog_get_info_by_fd and displayed via bpftool progs dump. Alexei noticed 4-byte hole in struct bpf_prog_info, so we put the u32 flags field in there, and we can keep adding bit fields in there without breaking user space.
