2009-02-02Add phenom CPU descriptor (Alexander Graf)aliguori
As part of my ongoing effort to make nested SVM useful, I started working to get VMware ESX run inside KVM. VMware couples itself pretty tightly to the CPUID, so it's a good idea to emulate a machine that officially supports SVM and should thus exploit the powers of nested virtualization. This patch adds a Phenom CPU identifier, that resembles a real-world phenom CPU as closely as possible.

This patch enables the vnc server to understand fundamental tight extensions.

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.

2009-01-29fix raw_aio_read\write error handling (Stefano Stabellini)aliguori
Currently when qemu_paio_read or qemu_paio_write return an error we call qemu_aio_release without removing the request from the list. I know that in the current implementation qemu_paio_write\read don't return any error, but still the behavior is wrong, especially considering that the implementation of these two functions is likely to change in is the future.

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.
