I'm all for a good entropy source for early boot. :) I need to figure out what's needed for relocation support first though, before we can really tackle kernel base-address randomization on ARM. I haven't had a chance to look around too closely yet, but it seems like only x86 and ppc do this currently? Has anyone looked in detail and what would be needed on ARM for CONFIG_RELOCATABLE behavior? -Kees -- Kees Cook Chrome OS Security -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
