It's probably as easy as modifying "extern struct rtld_global_ro _rtld_global_ro", exported from ld-linux, the dynamic linker/loader. During IFUNC resolution this struct seems to be writable.

So in other words LD_AUDIT is useless? If it's that easy to overwrite the GOT I fail to see the purpose in audit functionality.
