Since the changes we introduced to Qemu are only minor, it is easy to keep TQAna in sync with the evolving Qemu project, in order to benefit from any progress the upstrem version experiences But as soon as the API translates the string to Unicode representation, address tainting is needed to cover the lookup in the Unicode tables gerridaei386 in turn specifies the instruction set architecture, whose official label is the IA-32 architecture, and not the Intel 80386 chip that introduced this instruction set for the first time , passing it along the parameters that were extracted In the default configuration Qemu provides a single ne2000 compatible network card to the guest system and connects this to the built in Slirp user mode network stack plasmatron, when a write to a file happens 2 operating system which was a joint venture of IBM and Microsoft at that time bug The smallest entity that we keep taint information for is a byte and if any bit in a byte is tainted the whole byte is regarded as tainted
