The ld.so code must use the global variable __pointer_chk_guard_local. The libc code must use the tcbhead_t value. C and asm versions are needed. See the x86-64 version All needs to be done for archs other than x86 and x86-64 (although 1 is done for ppc). -- ➧ Ulrich Drepper ➧ Red Hat, Inc. ➧ 444 Castro St ➧ Mountain View, CA ❖
