-Both proto_register_libvirt() and proto_reg_handoff_libvirt() are

-Subject: [PATCH 2/8] wireshark: Switch header files to #pragma once
-Content-type: text/plain
-
-The genxdrstub.pl script generates some header files. But they
-use the old pattern to guard against multiple inclusion:
-
-  #ifndef SOMETHING_H
-  #define SOMETHING_H
-  ...
-  #endif
-
-Change the script to generate just '#pragma once' used everywhere
-else in our code.

-Subject: [PATCH 4/8] wireshark: Fix int type of some virNetMessageHeader
- members
-Content-type: text/plain
-
-Our virNetMessageHeader is a struct that's declared as follows:
-
-  struct virNetMessageHeader {
-      unsigned prog;
-      unsigned vers;
-      int proc;
-      virNetMessageType type;
-      unsigned serial;
-      virNetMessageStatus status;
-  };
-
-Now, per RFC 4506 enums are also encoded as signed integers. This
-means, that only 'prog', 'vers' and 'serial' are really unsigned
-integers. The others ('proc', 'type' and 'status') are encoded as
-signed integers. Fix their type when dissecting.
-
-While at it, also follow latest trend in wireshark and switch
-from guint32 to uint32_t.

-Content-type: text/plain
-
-The get_program_data() function returns a pointer (in this
-specific case to an array of procedure strings) which, if
-non-NULL is then passed val_to_str(). Well, if val_to_str() sees
-NULL it is treated gracefully, i.e. like if the numeric value
-'proc' wasn't found in the array.
-
-Therefore, there's no need to special case call to
-col_append_fstr(). Both result into the same behaviour.

-Subject: [PATCH 6/8] wireshark: Introduce and use vir_val_to_str()
-Content-type: text/plain
-
-Wireshark offers val_to_str() function which converts numeric
-value to string by looking up value ('val') in an array ('vs') of
-<val, string> pairs. If no corresponding string is found, then
-the value is formatted using given 'fmt' string.
-
-Starting from wireshark-4.6.0 not only this function gained
-another argument but also returns a strdup()-ed string. To keep
-our code simple, let's introduce a wrapper so which can be then
-adjusted as needed.

-Subject: [PATCH 7/8] wireshark: Don't leak column strings
-Content-type: text/plain
-
-One of the problems of using val_to_str() is that it may return a
-const string from given table ('vs'), OR return an allocated one.
-Since the caller has no idea which case it is, it resides to safe
-option and don't free returned string. But that might lead to a
-memleak. This behaviour is fixed with wireshark-4.6.0 and support
-for it will be introduced soon. But first, make vir_val_to_str()
-behave like fixed val_to_str() from newer wireshark: just always
-allocate the string.
-
-Now, if val_to_str() needs to allocate new memory it obtains
-allocator by calling wmem_packet_scope() which is what we may do
-too.
-
-Hand in hand with that, we need to free the memory using the
-correct allocator, hence wmem_free(). But let's put it into a
-wrapper vir_wmem_free() because just like val_to_str(), it'll
-need additional argument when adapting to new wireshark.
-
-Oh, and freeing the memory right after col_add_fstr() is safe as
-it uses vsnprintf() under the hood to format passed args.
-
-One last thing, the wmem.h file used to live under epan/wmem/ but
-then in v3.5.0~240 [1] was moved to wsutil/wmem/.

-Subject: [PATCH 8/8] wireshark: Adapt to wireshark-4.6.0
-Content-type: text/plain
-
-The main difference is that wmem_packet_scope() is gone [1] but
-the packet_info struct has 'pool` member which points to the
-allocator used for given packet.
-
-Unfortunately, while we were given pointer to packet_info at the
-entry level to our dissector (dissect_libvirt() ->
-tcp_dissect_pdus() -> dissect_libvirt_message()) it was never
-propagated to generated/primitive dissectors.
-
-But not all dissectors need to allocate memory, so mark the new
-argument as unused. And while our generator could be rewritten so
-that the argument is annotated as unused iff it's really unused,
-I couldn't bother rewriting it. It's generated code after all.
-Too much work for little gain.
-
-Another significant change is that val_to_str() now requires new
-argument: pointer to allocator to use because it always allocates
-new memory [2][3].

+Date: Mon, 14 Jun 2010 15:53:59 +0100
+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.
+
+* src/util/storage_file.c: remove type field from FileTypeInfo

+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 06/11] Convert all disk backing store loops to shared helper API
+
+Update the QEMU cgroups code, QEMU DAC security driver, SELinux
+and AppArmour security drivers over to use the shared helper API
+virDomainDiskDefForeachPath().
+
+* src/qemu/qemu_driver.c, src/qemu/qemu_security_dac.c,
+  src/security/security_selinux.c, src/security/virt-aa-helper.c:
+  Convert over to use virDomainDiskDefForeachPath()

+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

+
+Record a default driver name/type in capabilities struct. Use this
+when parsing disks if value is not set in XML config.

+* src/conf/capabilities.h: Record default driver name/type for disks
+* src/conf/domain_conf.c: Fallback to default driver name/type
+  when parsing disks
+* src/qemu/qemu_driver.c: Set default driver name/type to raw

+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 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.

+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
