[Qemu-block] [PATCH] ide: fix ATAPI command permissions

2015-09-09 Thread John Snow
We're a little too lenient with what we'll let an ATAPI drive handle. Clamp down on the IDE command execution table to remove CD_OK permissions from commands that are not and have never been ATAPI commands. For ATAPI command validity, please see: - ATA4 Section 6.5 ("PACKET Command feature set")
