Subject: PPC64 AT_IGNOREPPC question
Date: Sat, 08 Sep 2007 03:15:25 +0200 [thread overview]
Message-ID: <m3odgehs9e.fsf@dhcp-lab-156.englab.brq.redhat.com> (raw)
include/asm-powerpc/elf.h:289
Why we need the second AT_IGNOREPPC entry here?
There is a mm_struct->saved_auxv overflow on PPC64 with AT_VECTOR_SIZE
== 44 (may be on PPC32 too, not checked) when adding all entries to
it. I've removed the second AT_IGNOREPCC from ARCH_DLINFO to prevent
overflowing, checked it on IBM OpenPower 720 and a system (Fedora 7) is
going on as well. Have I missed some tricky thing?
