2014-12-10qemu-iotests: 060: Filter the real disk sizeKevin Wolf

2014-12-10block: do not use get_clock()Paolo Bonzini
Use the external qemu-timer API instead. No one else should be calling cpu_get_clock(), get_clock() and get_clock_realtime() directly; they are internal functions and they should be confined to qemu-timer.c and cpus.c (where the icount implementation resides). All accesses should go through qemu_clock_get_ns.

2014-12-10block: Don't probe for unknown backing file formatKevin Wolf
If a qcow2 image specifies a backing file format that doesn't correspond to any format driver that qemu knows, we shouldn't fall back to probing, but simply error out. Not looking up the backing file driver in bdrv_open_backing_file(), but just filling in the "driver" option if it isn't there moves us closer to the goal of having everything in QDict options and gets us the error handling of bdrv_open(), which correctly refuses unknown drivers.

2014-12-10qcow2: Fix header extension size checkKevin Wolf
After reading the extension header, offset is incremented, but not checked against end_offset any more. This way an integer overflow could happen when checking whether the extension end is within the allowed range, effectively disabling the check. This patch adds the missing check and a test case for it.

2014-12-10blockdev: acquire AioContext in QMP 'transaction' actionsStefan Hajnoczi
The transaction QMP command performs operations atomically on a group of drives. This command needs to acquire AioContext in order to work safely when virtio-blk dataplane IOThreads are accessing drives. The transactional nature of the command means that actions are split into prepare, commit, abort, and clean functions. Acquire the AioContext in prepare and don't release it until one of the other functions is called. This prevents the IOThread from running the AioContext before the transaction has completed.

2014-12-10raw: Prohibit dangerous writes for probed imagesKevin Wolf
If the user neglects to specify the image format, QEMU probes the image to guess it automatically, for convenience. Relying on format probing is insecure for raw images (CVE-2008-2004). If the guest writes a suitable header to the device, the next probe will recognize a format chosen by the guest. A malicious guest can abuse this to gain access to host files, e.g. by crafting a QCOW2 header with backing file /etc/shadow. Commit 1e72d3b (April 2008) provided -drive parameter format to let users disable probing. Commit f965509 (March 2009) extended QCOW2 to optionally store the backing file format, to let users disable backing file probing. QED has had a flag to suppress probing since the beginning (2010), set whenever a raw backing file is assigned. All of these additions that allow to avoid format probing have to be specified explicitly. The default still allows the attack. In order to fix this, commit 79368c8 (July 2010) put probed raw images in a restricted mode, in which they wouldn't be able to overwrite the first few bytes of the image so that they would identify as a different image. If a write to the first sector would write one of the signatures of another driver, qemu would instead zero out the first four bytes. This patch was later reverted in commit 8b33d9e (September 2010) because it didn't get the handling of unaligned qiov members right. Today's block layer that is based on coroutines and has qiov utility functions makes it much easier to get this functionality right, so this patch implements it. The other differences of this patch to the old one are that it doesn't silently write something different than the guest requested by zeroing out some bytes (it fails the request instead) and that it doesn't maintain a list of signatures in the raw driver (it calls the usual probe function instead). Note that this change doesn't introduce new breakage for false positive cases where the guest legitimately writes data into the first sector that matches the signatures of an image format (e.g. for nested virt): These cases were broken before, only the failure mode changes from corruption after the next restart (when the wrong format is probed) to failing the problematic write request. Also note that like in the original patch, the restrictions only apply if the image format has been guessed by probing. Explicitly specifying a format allows guests to write anything they like.

2014-12-10block: Add blk_add_close_notifier() for BBMax Reitz
Adding something like a "delete notifier" to a BlockBackend would not make much sense, because whoever is interested in registering there will probably hold a reference to that BlockBackend; therefore, the notifier will never be called (or only when the notifiee already relinquished its reference and thus most probably is no longer interested in that notification). Therefore, this patch just passes through the close notifier interface of the root BDS. This will be called when the device is ejected, for instance, and therefore does make sense.
