From c1b93c07b3ac3204c6a42a7f7b6217e36f44df4f Mon Sep 17 00:00:00 2001 From: Eduard Zingerman Date: Wed, 6 Mar 2024 12:45:20 +0200 Subject: selftests/bpf: Bad_struct_ops test When loading struct_ops programs kernel requires BTF id of the struct_ops type and member index for attachment point inside that type. This makes impossible to use same BPF program in several struct_ops maps that have different struct_ops type. Check if libbpf rejects such BPF objects files.
