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? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
