lkdtm: add function for testing .rodata section This adds a function that lives in the .rodata section. The section flags are corrected using objcopy since there is no way with gcc to declare section flags in an architecture-agnostic way. Signed-off-by: Kees Cook <keescook@chromium.org>

/*
* This includes functions that are meant to live entirely in .rodata

lkdtm: silence warnings about function declarations When building under W=1, the lack of lkdtm.h in lkdtm_usercopy.c and lkdtm_rodata.c was discovered. This fixes the issue and consolidates the common header and the pr_fmt macro for simplicity and regularity across each test source file. Signed-off-by: Kees Cook <keescook@chromium.org>
