Andrii Nakryiko 71754ee427 libbpf: fix offsetof() and container_of() to work with CO-RE ... [ Upstream commit bdeeed3498 ] It seems like __builtin_offset() doesn't preserve CO-RE field relocations properly. So if offsetof() macro is defined through __builtin_offset(), CO-RE-enabled BPF code using container_of() will be subtly and silently broken. To avoid this problem, redefine offsetof() and container_of() in the form that works with CO-RE relocations more reliably.
