The original implementation added a hack to check_mem_access() to prevent programs from writing into insn arrays. To get rid of this hack, enforce BPF_F_RDONLY_PROG on map creation. Also fix the corresponding selftest, as the error message changes with this patch. Suggested-by: Alexei Starovoitov <[email protected]> Signed-off-by: Anton Protopopov <[email protected]>
