qcow2 corruption: Fix alloc_cluster_link_l2 (Kevin Wolf)
|
|
|
|
This patch fixes a qcow2 corruption bug introduced in SVN Rev 5861. L2 tables
|
|
are big endian, so entries must be converted before being passed to functions.
|
|
|
|
This bug is easy to trigger. The following script will create and destroy a
|
|
qcow2 image (the header is gone after three loop iterations):
|
|
|
|
#!/bin/bash
|
|
qemu-img create -f qcow2 test.qcow 1M
|
|
for i in $(seq 1 10); do
|
|
qemu-system-x86_64 -hda test.qcow -monitor stdio > /dev/null 2>&1 <<EOF
|
|
savevm test-$i
|
|
quit
|
|
EOF
|
|
done
