[Qemu-devel] [PATCH v2 for-2.0 0/2] Bounds checking for VDI

[Jeff Cody]

This is v2 of the patches from Stefan Hajnoczi's pull request for CVE patches.

Changes from v1:

    Patch 1: * Use DEFAULT_CLUSTER_SIZE instead of new
               VDI_BLOCK_SIZE (thanks Stefan Weil)
             * More informative error messages (thanks Stefan Weil)
             * Return -ENOTSUP instead of -EINVAL on images
               that exceed the maximum allowed size.  These may
               not be against spec, they are just currently unsupported.
             * Fix wrong error message, introduced in commit 
               5b7aa9b56d1bfc79916262f380c3fc7961becb50 (thanks Stefan Weil)

    Patch 2: * Update tests results to take in account new error messages.
