[Qemu-devel] [PATCH 0/5] qcow2: Add metadata overlap checks |
Date: |
Mon, 26 Aug 2013 15:04:15 +0200 |
If a qcow2 image file becomes corrupted, any write may inadvertently
overwrite important metadata structures such as the L1 table. This
series adds functionality for detecting, preventing and (to some
extent) repairing such collisions.
Max Reitz (5):
qcow2: Add corrupt bit
qcow2: Metadata overlap checks
qcow2: Employ metadata overlap checks
qcow2: Check allocations in qcow2_check
qemu-iotests: Overlapping cluster allocations
