2009-01-29check SCSI read/write requests against max LBA (Rik van Riel)aliguori
The bdrv layer uses a signed offset. Furthermore, block-raw-posix only seeks when that offset is positive. Passing a negative offset to block-raw-posix can result in data being written at the current seek cursor's position. It may be possible to exploit this to seek to the end of the disk and extend the virtual disk by writing data to a negative sector offset. After a reboot, this could lead to the guest having a larger disk than it had before. Close the hole by sanity checking the lba against the size of the disk.

2009-01-28SCSI divide capacity by s->cluster_size (Rik van Riel)aliguori
Paul Brook pointed out that the number of sectors reported by the SCSI read capacity commands needs to be divided by s->cluster_size, because bdrv_get_geometry reports the number of 512 byte sectors, while emulated CDROMs report 2048 byte sectors back to the guest. This has no consequences for emulated hard disks, which use a cluster size of 1. aliguori: fixed typo Signed-off-by: Rik van Riel <riel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@6469 c046a42c-6fe2-441c-8c8c-71466251a162
2009-01-28support >2TB SCSI disks (Rik van Riel)aliguori
Implement SCSI READ(16), WRITE(16) and SAI READ CAPACITY(16) commands, so SCSI disks larger than 2TB can work with guests that support these newer SCSI commands. The cast to (uint64_t) is needed because otherwise gcc will use a signed int, which gets sign extended into uint64_t lba, resulting in bad block numbers for READ 10 and READ 16 with block numbers larger than 2^31.

2009-01-28fix signed/unsigned overflows in SCSI disk (Rik van Riel)aliguori
Sector numbers can overflow on a virtual scsi disk of over 1TB in size. Qemu's bdrv_read expects an int64_t, so fix the overflow by going to that data type. On large disks, we clip the capacity to 2TB instead of returning "capacity modulo 2TB". Turn sector_count into an unsigned to prevent a signed/unsigned overflow with SCSI transfers larger than 2TB. We're unlikely to ever hit this bug, but fixing it is just one line.

2008-12-07SCSI: Handle inquiry commands of varying length (Justin Chevrier).balrog
Openserver 5.0.5 sends an Inquiry command to the emulated SCSI disk expecting a response length of 40 bytes. Currently the response to an Inquiry command is hardcoded to 36 bytes. When receiving a response of length 36 instead of 40 Openserver panics. Modifications to original patch based on feedback from Ryan Harper and Paul Brook. Thanks guys.
