Full relro and DSOs

[Erwan Legrand]

Hi all,

Quick question: in order to fully prevent addresses being overwritten
in .got.plt in a Linux AMD64 process, all binaries must be linked with
-z relro and -z now, right?

What happens if the executable was linked with these flags but the
libraries were not? Does the loader perform lazy binding when loading
DSOs in this case? I think it is what the man page suggests, but it is
not crystal clear. (To me at least.)

Thanks,
