Subject: [Qemu-devel] [PATCH 0/4] Misc qcow2 corruption checks
Date: Wed, 1 Nov 2017 17:42:21 +0200 [thread overview]
Message-ID: <cover.1509550787.git.berto@igalia.com> (raw)
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
