Revised block device address range patch
The original patch adds checks to the main bdrv_XXX apis to validate that
the I/O operation does not exceed the bounds of the disk - ie beyond the
total_sectors count. This works correctly for bdrv_XXX calls from the IDE
driver. With disk formats like QCow though, bdrv_XXX is re-entrant,
because the QCow driver uses the block APIs for dealing with its underlying
file. The problem is that QCow files are grow-on-demand, so writes will
*explicitly* be beyond the end of the file. The original patch blocks any
I/O operation which would cause the QCow file to grow, resulting it more
or less catasatrophic data loss.
Basically the bounds checking needs to distinguish between checking for
the logical disk extents, vs the physical disk extents. For raw files
these are the same so initial tests showed no problems, but for QCow
format disks they are different & thus we see a problem
What follows is a revised patch which introduces a flag BDRV_O_AUTOGROW
which can be passed to bdrv_open to indicate that the files can be allowed
to automatically extend their extents. This flag should only be used by
internal block drivers such as block-qcow2.c, block-vmdk.c In my testing
this has fixed the qcow corruption, and still maintains the goal of Ian's
original patch which was to prevent the guest VM writing beyond the logical
disk extents.
