The load_image() function is deprecated, as it does not let the
caller specify how large the buffer to read the file into is.
Use the glib g_file_get_contents() function instead, which does
the whole "allocate memory for the file and read it in" operation.

The filename length in MTP metadata is specified by the guest. By
trusting it directly it'd theoretically be possible to get the host to
write memory parts outside the filename buffer into a filename. In
practice though there are usually NUL bytes stopping the string
operations.
Also use the opportunity to not assign the filename member twice.

Open files and directories with O_NOFOLLOW to avoid symlinks attacks.
While being at it also add O_CLOEXEC.
usb-mtp only handles regular files and directories and ignores
everything else, so users should not see a difference.
Because qemu ignores symlinks, carrying out a successful symlink attack
requires swapping an existing file or directory below rootdir for a
symlink and winning the race against the inotify notification to qemu.

Architecturally, it's possible for an AArch64 machine to have
all of its RAM over the 4GB mark, but our kernel/initrd loading
code in boot.c assumes that the upper half of the addresses
to load these images to is always zero. Write the whole 64 bit
address into the bootloader code fragment, not just the low half.
Note that, currently, none of the existing QEMU machines have
their main memory over 4GBs, so this was not a user-visible bug.

9pfs: deprecate handle backend
This backend raise some concerns:
- doesn't support symlinks
- fails +100 tests in the PJD POSIX file system test suite [1]
- requires the QEMU process to run with the CAP_DAC_READ_SEARCH
capability, which isn't recommended for security reasons
This backend should not be used and wil be removed. The 'local'
backend is the recommended alternative.

it might not be actually aligned enough for that pointer type (and
thus cause a crash on dereference on some host architectures). Newer
versions of clang warn about this. Avoid the bug by not using the
"modify in place" byte swapping functions.

Just like on other architectures, we should stop the clock while the guest
is not running. This is already properly done for TCG. Right now, doing an
offline migration (stop, migrate, cont) can easily trigger stalls in the
guest.
Even doing a
(hmp) stop
... wait 2 minutes ...
(hmp) cont
will already trigger stalls.
So whenever the guest stops, backup the KVM TOD. When continuing to run
the guest, restore the KVM TOD.
One special case is starting a simple VM: Reading the TOD from KVM to
stop it right away until the guest is actually started means that the
time of any simple VM will already differ to the host time. We can
simply leave the TOD running and the guest won't be able to recognize
it.
For migration, we actually want to keep the TOD stopped until really
starting the guest. To be able to catch most errors, we should however
try to set the TOD in addition to simply storing it. So we can still
catch basic migration problems.
If anything goes wrong while backing up/restoring the TOD, we have to
ignore it (but print a warning). This is then basically a fallback to
old behavior (TOD remains running).
I tested this very basically with an initrd:
1. Start a simple VM. Observed that the TOD is kept running. Old
behavior.
2. Ordinary live migration. Observed that the TOD is temporarily
stopped on the destination when setting the new value and
correctly started when finally starting the guest.
3. Offline live migration. (stop, migrate, cont). Observed that the
TOD will be stopped on the source with the "stop" command. On the
destination, the TOD is temporarily stopped when setting the new
value and correctly started when finally starting the guest via
"cont".
4. Simple stop/cont correctly stops/starts the TOD. (multiple stops
or conts in a row have no effect, so works as expected)
In the future, we might want to send the guest a special kind of time sync
interrupt under some conditions, so it can synchronize its tod to the
host tod. This is interesting for migration scenarios but also when we
get time sync interrupts ourselves. This however will most probably have
to be handled in KVM (e.g. when the tods differ too much) and is not
desired e.g. when debugging the guest (single stepping should not
result in permanent time syncs). I consider something like that an add-on
on top of this basic "don't break the guest" handling.

While most developers are now using UTF-8 environments, it's
harder to guarantee that error messages will be output to
a multibyte locale. Rather than risking error messages that
get corrupted into mojibake when the user runs qemu in a
non-multibyte locale, let's stick to straight ASCII error
messages, rather than assuming that our use of UTF-8 in source
code string constants will work unchanged in other locales.

The token field contains the (guest-filled) state of the qtd, which
indicates whenever the other fields are valid or not. So make sure
we read the token first, otherwise we may end up with an stale next
pointer:
(1) ehci reads next
(2) guest writes next
(3) guest writes token
(4) ehci reads token
(5) ehci operates with stale next.
Typical effect is that qemu doesn't notice that the guest appends new
qtds to the end of the queue. Looks like the usb device stopped
responding. Linux can recover from that, but leaves a message in the
kernel log that it did reset the usb device in question.

Note that this bug is exploitable by a guest to escape

introduced the bug was only made after the 3.0 release,
and so it is not present in any released QEMU versions.

Under heavy IO (e.g. fio) the queue is not checked frequently enough for
pending commands. As a result some pending commands are timed out by the
linux sym53c8xx driver, which sends SCSI Abort messages for the timed out
commands. The SCSI Abort messages result in linux errors, which show up
on the console and in /var/log/messages.
e.g.
sd 0:0:3:0: [sdd] tag#33 ABORT operation started
scsi target0:0:3: control msgout:
80 20 47 d
sd 0:0:3:0: ABORT operation complete.
scsi target0:0:4: message d sent on bad reselection

current command, check for a pending command on the queue and if one
exists call lsi_reselect().

When using the 9P2000.u version of the protocol, the following shell
command line in the guest can cause QEMU to crash:
while true; do rm -rf aa; mkdir -p a/b & touch a/b/c & mv a aa; done
With 9P2000.u, file renaming is handled by the WSTAT command. The
v9fs_wstat() function calls v9fs_complete_rename(), which calls
v9fs_fix_path() for every fid whose path is affected by the change.
The involved calls to v9fs_path_copy() may race with any other access
to the fid path performed by some worker thread, causing a crash like
shown below:

When the submission and completion queues are being torn down
the IRQ will be asserted for the completion queue when the
submsission queue is deleted. Then when the completion queue
is deleted it stays asserted. Thus, on systems that do
not use MSI, no further interrupts can be triggered on the host.
Linux sees this as a long delay when unbinding the nvme device.
Eventually the interrupt timeout occurs and it continues.
To fix this we ensure we deassert the IRQ for a CQ when it is
deleted.

Because the CMB BAR has a min_access_size of 2, if you read the last
byte it will try to memcpy *2* bytes from n->cmbuf, causing an off-by-one
error. This is CVE-2018-16847.
Another way to fix this might be to register the CMB as a RAM memory
region, which would also be more efficient. However, that might be a
change for big-endian machines; I didn't think this through and I don't
know how real hardware works. Add a basic testcase for the CMB in case
somebody does this change later on.

Recent commit 5b76ef50f6 fixed a race where v9fs_co_open2() could
possibly overwrite a fid path with v9fs_path_copy() while it is being
accessed by some other thread, ie, use-after-free that can be detected
by ASAN with a custom 9p client.
It turns out that the same can happen at several locations where
v9fs_path_copy() is used to set the fid path. The fix is again to
take the write lock.

Commit c8a35f1cf0 "fdc: use IsaDma interface instead of global DMA_*
functions" accidentally introduced a segfault in fdctrl_stop_transfer() for
non-DMA transfers.
If fdctrl->dma_chann has not been configured then the fdctrl->dma interface
reference isn't initialised during isabus_fdc_realize(). Unfortunately
fdctrl_stop_transfer() unconditionally references the DMA interface when
finishing the transfer causing a NULL pointer dereference.
Fix the issue by adding a check in fdctrl_stop_transfer() so that the DMA
interface reference and release method is only invoked if fdctrl->dma_chann
has been set.

Commit af7d64ede0 (hw/arm/sysbus-fdt: Allow device matching with DT
compatible value) introduced a match_fn callback which gets called
for each registered combo to check whether a sysbus device can be
dynamically instantiated. However the callback gets called even if
the device type does not match the binding combo typename field.
This causes an assert when passing "-device ramfb" to the qemu
command line as vfio_platform_match() gets called on a non
vfio-platform device.
To fix this regression, let's change the add_fdt_node() logic so
that we first check the type and if the match_fn callback is defined,
then we also call it.
Binding combos only requesting a type check do not define the
match_fn callback.

The assumption that the fid cannot be used by any other operation is
wrong. At least, nothing prevents a misbehaving client to create a
file with a given fid, and to pass this fid to some other operation
at the same time (ie, without waiting for the response to the creation
request). The call to v9fs_path_copy() performed by the worker thread
after the file was created can race with any access to the fid path
performed by some other thread. This causes use-after-free issues that
can be detected by ASAN with a custom 9p client.
Unlike other operations that only read the fid path, v9fs_co_open2()
does modify it. It should hence take the write lock.

at the end of the list and checking that 0xb0 was added before.

object_new() returns a new backend with refcount == 1 and
then later object_property_add_child() increases refcount to 2
So when ivshmem is destroyed, the backend it has created isn't
destroyed along with it as children cleanup will bring
backend's refcount only to 1, which leaks backend including
resources it is using.
Drop the original reference from object_new() once backend
is attached to its parent.

The 'q35' machine type implements an Intel Series 3 chipset,
of which there are several variants:
https://www.intel.com/Assets/PDF/datasheet/316966.pdf
The key difference between the 82P35 MCH ('p35', PCI device ID 0x29c0)
and 82Q35 GMCH ('q35', PCI device ID 0x29b0) variants is that the latter
has an integrated graphics adapter. QEMU does not implement integrated
graphics, so uses the PCI ID for the 82P35 chipset, despite calling the
machine type 'q35'. Thus we rename the PCI device ID constant to reflect
reality, to avoid confusing future developers. The new name more closely
matches what pci.ids reports it to be:
$ grep P35 /usr/share/hwdata/pci.ids | grep 29
29c0 82G33/G31/P35/P31 Express DRAM Controller
29c1 82G33/G31/P35/P31 Express PCI Express Root Port
29c4 82G33/G31/P35/P31 Express MEI Controller
29c5 82G33/G31/P35/P31 Express MEI Controller
29c6 82G33/G31/P35/P31 Express PT IDER Controller
29c7 82G33/G31/P35/P31 Express Serial KT Controller
$ grep Q35 /usr/share/hwdata/pci.ids | grep 29
29b0 82Q35 Express DRAM Controller
29b1 82Q35 Express PCI Express Root Port
29b2 82Q35 Express Integrated Graphics Controller
29b3 82Q35 Express Integrated Graphics Controller
29b4 82Q35 Express MEI Controller
29b5 82Q35 Express MEI Controller
29b6 82Q35 Express PT IDER Controller
29b7 82Q35 Express Serial KT Controller
Arguably the QEMU machine type should be named 'p35'. At this point in
time, however, it is not worth the churn for management applications &
documentation to worry about renaming it.

In exynos4210_init() we allocate memory for an Exynos4210State
struct. Generally devices can assume that the memory allocated
for their state struct is zero-initialized; we broke that
assumption here by using g_new(). Use g_new0() instead.
(In particular, some code assumes that the various irq arrays
in the Exynos4210Irq sub-struct are zero-initialized.)
In the longer term, this code should be QOMified, and then
the struct memory will be allocated elsewhere and by functions
which always zero-initalize it; but for 3.1 this is a
simple fix.

There are 3 virtqueues (ctrl, event and cmd) for virtio scsi device,
but seabios will only set the physical address for the 3rd one (cmd).
Then in vhost_virtqueue_start(), virtio_queue_get_desc_addr()
will be 0 for ctrl and event vq.
In this case, ctrl and event vq are not initialized.
vhost_verify_ring_mappings may use uninitialized vhost_virtqueue
such that vhost_verify_ring_part_mapping returns ENOMEM.
When encountered this problem, we got the following logs:
qemu-system-x86_64: Unable to map available ring for ring 0
