Paolo, List Please find a small patch to the scsi emulation. This patch improves the checkign that the requested lbas are all available. We check both that lba+len is not going past the end of the device but also if lba+len < lba
This second condition could occur for deviously crafted scsi packets where lba is set to 0xffffffffffffffff and len is set to 2 in which case lba+len would wrap to 1
