Fix savevm after BDRV_FILE size enforcement
We now enforce that you cannot write beyond the end of a non-growable file.qcow2 files are not growable but we rely on them being growable to dosavevm/loadvm. Temporarily allow them to be growable by introducing a new...
block: support known backing format for image create and open (Uri Lublin)
Added a backing_format field to BlockDriverState.Added bdrv_create2 and drv->bdrv_create2 to create an image witha known backing file format.Upon bdrv_open2 if backing format is known use it, instead of...
new scsi-generic abstraction, use SG_IO (Christoph Hellwig)
Okay, I started looking into how to handle scsi-generic I/O in thenew world order.
I think the best is to use the SG_IO ioctl instead of the read/writeinterface as that allows us to support scsi passthrough on disk/cdrom...
Refactor aio callback allocation to use an aiocb pool (Avi Kivity)
Move the AIOCB allocation code to use a dedicate structure, AIOPool. AIOCBspecific information, such as the AIOCB size and cancellation routine, ismoved into the pool.
At present, there is exactly one pool per block format driver, maintaining...
Drop internal bdrv_pread()/bdrv_pwrite() APIs (Avi Kivity)
Now that scsi generic no longer uses bdrv_pread() and bdrv_pwrite(), we candrop the corresponding internal APIs, which overlap bdrv_read()/bdrv_write()and, being byte oriented, are unnatural for a block device....
Add internal scsi generic block API (Avi Kivity)
Add an internal API for the generic block layer to send scsi generic commandsto block format driver. This means block format drivers no longer needto consider overloaded nb_sectors parameters.

monitor: Rework early disk password inquiry (Jan Kiszka)
Reading the passwords for encrypted hard disks during early startup isbroken (I guess for quiet a while now): - No monitor terminal is ready for input at this point - Forcing all mux'ed terminals into monitor mode can confuse other...
Fix CVE-2008-0928 - insufficient block device address range checking (Anthony Liguori)
Introduce a growable flag that's set by bdrv_file_open(). Block devices shouldnever be growable, only files that are being used by block devices.
I went through Fabrice's early comments about the patch that was first applied....

Use an option rom instead of boot sector for -kernel
Generate an option rom instead of using a hijacked boot sector for kernelbooting. This just requires adding a small option ROM header and a few moreinstructions to the boot sector to take over the int19 vector and run our...

Fix CVE-2008-0928 - insufficient block device address range checking
