Misc qcow2 corruption checks This series contains a few checks that prevent QEMU from crashing under some scenarios with corrupted qcow2 images.
The first patch solves the crash reported here: https://bugs.launchpad.net/qemu/+bug/1728615 And the others solve similar crashes that I detected in the process of fixing this one. Regards, Berto Alberto Garcia (4): qcow2: Prevent allocating refcount blocks at offset 0 qcow2: Prevent allocating L2 tables at offset 0 qcow2: Don't open images with header.refcount_table_clusters == 0 qcow2: Add iotest for an empty refcount table block/qcow2-cluster.c | 7 +++++++ block/qcow2-refcount.c | 7 +++++++ block/qcow2.c | 6 ++++++ tests/qemu-iotests/060 | 32 ++++++++++++++++++++++++++++++++ tests/qemu-iotests/060.out | 25 +++++++++++++++++++++++++ 5 files changed, 77 insertions(+) -- 2.11.0
