* Preserve bound registers for pointer pass/returnIgor Zamyatin2015-07-091-0/+21
| | | | | | | | | | | | | | | | | | | | | | | We need to save/restore bound registers and add a BND prefix before branches in _dl_runtime_profile so that bound registers for pointer pass and return are preserved when LD_AUDIT is used. [BZ #18134] * sysdeps/i386/configure.ac: Set HAVE_MPX_SUPPORT. * sysdeps/i386/configure: Regenerated. * sysdeps/i386/dl-trampoline.S (PRESERVE_BND_REGS_PREFIX): New. (_dl_runtime_profile): Save and restore Intel MPX return bound registers when calling _dl_call_pltexit. Add PRESERVE_BND_REGS_PREFIX before return. * sysdeps/i386/link-defines.sym (LRV_BND0_OFFSET): New. (LRV_BND1_OFFSET): Likewise. * sysdeps/x86/bits/link.h (La_i86_retval): Add lrv_bnd0 and lrv_bnd1. * sysdeps/x86_64/dl-trampoline.S (_dl_runtime_profile): Fix typo in bndmov encoding. * sysdeps/x86_64/dl-trampoline.h: Properly save and restore Intel MPX bound registers. Add PRESERVE_BND_REGS_PREFIX before branch instructions to preserve bounds.

* rtld, i386: Fix cfi directive in audit trampoline codeJiri Olsa2011-08-291-2/+2
| | | | | | | | | | | _dl_runtime_profile function has wrong cfi directive when rewinding stack back for the pltexit path. Only 8 bytes - 2 'pop edx' instructions from the pltentry-only code should be rewinded back. With attached patch, I'm able to rewind stack correctly throught the rtld code from audit library callback.
