+Subject: [PATCH 01/11] Extract the backing store format as well as name, if available
+
+When QEMU opens a backing store for a QCow2 file, it will
+normally auto-probe for the format of the backing store,
+rather than assuming it has the same format as the referencing
+file. There is a QCow2 extension that allows an explicit format
+for the backing store to be embedded in the referencing file.
+This closes the auto-probing security hole in QEMU.
+
+This backing store format can be useful for libvirt users
+of virStorageFileGetMetadata, so extract this data and report
+it.
+
+QEMU does not require disk image backing store files to be in
+the same format the file linkee. It will auto-probe the disk
+format for the backing store when opening it. If the backing
+store was intended to be a raw file this could be a security
+hole, because a guest may have written data into its disk that
+then makes the backing store look like a qcow2 file. If it can
+trick QEMU into thinking the raw file is a qcow2 file, it can
+access arbitrary files on the host by adding further backing
+store links.
+
+To address this, callers of virStorageFileGetMeta need to be
+told of the backing store format. If no format is declared,
+they can make a decision whether to allow format probing or
+not.

+Subject: [PATCH 03/11] Refactor virStorageFileGetMetadataFromFD to separate functionality
+
+The virStorageFileGetMetadataFromFD did two jobs in one. First
+it probed for storage type, then it extracted metadata for the
+type. It is desirable to be able to separate these jobs, allowing
+probing without querying metadata, and querying metadata without
+probing.
+
+To prepare for this, split out probing code into a new pair of
+methods
+
+ virStorageFileProbeFormatFromFD
+ virStorageFileProbeFormat
+
+* src/util/storage_file.c, src/util/storage_file.h,
+ src/libvirt_private.syms: Introduce virStorageFileProbeFormat
+ and virStorageFileProbeFormatFromFD

+Subject: [PATCH 04/11] Require format to be passed into virStorageFileGetMetadata
+
+Require the disk image to be passed into virStorageFileGetMetadata.
+If this is set to VIR_STORAGE_FILE_AUTO, then the format will be
+resolved using probing. This makes it easier to control when
+probing will be used
+
+* src/qemu/qemu_driver.c, src/qemu/qemu_security_dac.c,
+ src/security/security_selinux.c, src/security/virt-aa-helper.c:
+ Set VIR_STORAGE_FILE_AUTO when calling virStorageFileGetMetadata.
+* src/storage/storage_backend_fs.c: Probe for disk format before
+ calling virStorageFileGetMetadata.
+* src/util/storage_file.h, src/util/storage_file.c: Remove format
+ from virStorageFileMeta struct & require it to be passed into
+ method.

+Subject: [PATCH 07/11] Pass security driver object into all security driver callbacks
+
+The implementation of security driver callbacks often needs
+to access the security driver object. Currently only a handful
+of callbacks include the driver object as a parameter. Later
+patches require this is many more places.
+
+* src/qemu/qemu_driver.c: Pass in the security driver object
+ to all callbacks
+* src/qemu/qemu_security_dac.c, src/qemu/qemu_security_stacked.c,
+ src/security/security_apparmor.c, src/security/security_driver.h,
+ src/security/security_selinux.c: Add a virSecurityDriverPtr
+ param to all security callbacks

+Subject: [PATCH 08/11] Disable all disk probing in QEMU driver & add config option to re-enable
+
+Disk format probing is now disabled by default. A new config
+option in /etc/qemu/qemu.conf will re-enable it for existing
+deployments where this causes trouble

+Subject: [PATCH 10/11] Rewrite qemu-img backing store format handling
+
+When creating qcow2 files with a backing store, it is important
+to set an explicit format to prevent QEMU probing. The storage
+backend was only doing this if it found a 'kvm-img' binary. This
+is wrong because plenty of kvm-img binaries don't support an
+explicit format, and plenty of 'qemu-img' binaries do support
+a format. The result was that most qcow2 files were not getting
+a backing store format.
+
+This patch runs 'qemu-img -h' to check for the two support
+argument formats
+
+ '-o backing_format=raw'
+ '-F raw'
+
+and use whichever option it finds
+
+* src/storage/storage_backend.c: Query binary to determine
+ how to set the backing store format

+Subject: [PATCH] CVE-2010-2242 Apply a source port mapping to virtual network masquerading
+
+IPtables will seek to preserve the source port unchanged when
+doing masquerading, if possible. NFS has a pseudo-security
+option where it checks for the source port <= 1023 before
+allowing a mount request. If an admin has used this to make the
+host OS trusted for mounts, the default iptables behaviour will
+potentially allow NAT'd guests access too. This needs to be
+stopped.
+
+With this change, the iptables -t nat -L -n -v rules for the
+default network will be
+
+Chain POSTROUTING (policy ACCEPT 95 packets, 9163 bytes)
