This is done deliberately, see coregrind/m_initimg/initimg-linux.c
(setup_client_stack):
case AT_SYSINFO_EHDR: {
/* Trash this, because we don't reproduce it */
const NSegment* ehdrseg =
VG_(am_find_nsegment)((Addr)auxv->u.a_ptr);
vg_assert(ehdrseg);
VG_(am_munmap_valgrind)(ehdrseg->start, ehdrseg->end -
ehdrseg->start);
auxv->a_type = AT_IGNORE;
break;
}
So the application should use actual syscalls instead of using that magic vdso
page when running under valgrind.
Is there a reason you need AT_SYSINFO_EHDR?
