Jakub Kicinski d777b2ddbe bpf: don't zero out the info struct in bpf_obj_get_info_by_fd() ... The buffer passed to bpf_obj_get_info_by_fd() should be initialized to zeros. Kernel will enforce that to guarantee we can safely extend info structures in the future. Making the bpf_obj_get_info_by_fd() call in libbpf perform the zeroing is problematic, however, since some members of the info structures may need to be initialized by the callers (for instance pointers to buffers to which kernel is to dump translated and jited images). Remove the zeroing and fix up the in-tree callers before any kernel has been released with this code. As Daniel points out this seems to be the intended operation anyway, since commit 95b9afd398 ("bpf: Test for bpf ID") is itself setting the buffer pointers before calling bpf_obj_get_info_by_fd().
