From 953440bd12608a20007ee5da5ab69fbbe910bd28 Mon Sep 17 00:00:00 2001

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 02/11] Remove 'type' field from FileTypeInfo struct
Instead of including a field in FileTypeInfo struct for the
disk format, rely on the array index matching the format.
Use verify() to assert the correct number of elements in the
array.

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

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 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

how to set the backing store format

Subject: [PATCH 11/11] Use the extract backing store format in storage volume lookup
The storage volume lookup code was probing for the backing store
format, instead of using the format extracted from the file
itself. This meant it could report in accurate information. If
a format is included in the file, then use that in preference,
with probing as a fallback.

From 112a309bc7839e95c558b535143f855ce89cca8c Mon Sep 17 00:00:00 2001

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)
pkts bytes target prot opt in out source destination
14 840 MASQUERADE tcp -- * * 192.168.122.0/24 !192.168.122.0/24 masq ports: 1024-65535
75 5752 MASQUERADE udp -- * * 192.168.122.0/24 !192.168.122.0/24 masq ports: 1024-65535
0 0 MASQUERADE all -- * * 192.168.122.0/24 !192.168.122.0/24
* src/network/bridge_driver.c: Add masquerade rules for TCP
and UDP protocols
* src/util/iptables.c, src/util/iptables.c: Add source port
mappings for TCP & UDP protocols when masquerading.
