Levin" <ldv@...linux.org> Subject: "bpf: Improve the info.func_info and info.func_info_rec_size behavior" breaks strace self tests Hello, the kernel commit 7337224fc150 ("bpf: Improve the info.func_info and info.func_info_rec_size behavior") breaks one of strace's self tests: FAIL: bpf-obj_get_info_by_fd-prog-v.gen Looking into the kernel commit, it seems that the user space visible uapi change is intentional; even though it might break existing user space. To reproduce: git clone https://gitlab.com/strace/strace.git cd strace ./bootstrap ./configure make -j $(nproc) cd tests make -j $(nproc) check
