Nick Desaulniers and Xin Liu separately reported that int type might have greater-than-16 byte size ([1] and [2]). More specifically, the reported int type sizes are 1024 and 64 bytes. The libbpf and bpf program does not really support any int type greater than 16 bytes. Therefore, with current pahole, btf encoding will fail with greater-than-16 byte int types. Since for now bpf does not support '> 16' bytes int type, the simplest way is to sanitize such types, similar to existing conditions like '!byte_sz' and 'byte_sz & (byte_sz - 1)'. This way, pahole won't call libbpf with an unsupported int type size. The patch [3] was proposed before. Now I resubmitted this patch as there are another failure due to the same issue.
