Problem description: -------------------- The issue reported by one of the customer was able to read LBA beyond the array reported size with "sg_read" utility. If N is the last block address reported, then should not be able to read past N, i.e. N+1. But in their case, reported last LBA=143134719. So should not have been able to read with LBA=143134720, but it is read without failure, which means reported size to the OS is not correct and is less than the actual last block address. Solution: --------- Firmware layer exposes lesser container capacity than the actual one. It exposes [Actual size - Spitfire space(10MB)] to the OS, IO's to the 10MB should be prohibited from the Linux driver. Driver checks LBA boundary, if its greater than the array reported size then sets sensekey to HARDWARE_ERROR and sends the notification to the MID layer.
