[Qemu-devel] [PATCH for-2.1] block/backup: Fix hang for unaligned image

From:	Kevin Wolf
Subject:	[Qemu-devel] [PATCH for-2.1] block/backup: Fix hang for unaligned image size
Date:	Mon, 7 Jul 2014 16:53:44 +0200
When doing a block backup of an image with an unaligned size (with
respect to the BACKUP_CLUSTER_SIZE), qemu would check the allocation
status of sectors after the end of the image. bdrv_is_allocated()
returns a result that is valid for 0 sectors in this case, so the backup
job ran into an endless loop.

Stop looping when seeing a result valid for 0 sectors, we're at EOF then.

The test case looks somewhat unrelated at first sight because I
originally tried to reproduce a different suspected bug that turned out
to not exist. Still a good test case and it accidentally found this one.
