31fb4444a4 usb-ccid: add check message size checks
Check message size too when figuring whenever we should expect more data.
Fix debug message to show useful data, p->iov.size is fixed anyway if we
land there, print how much we got meanwhile instead.

Also check announced message size against actual message size.  That
is a more general fix for CVE-2017-5898 than commit "c7dfbf3 usb: ccid:
check ccid apdu length".

0aeebc73b7 usb-ccid: better bulk_out error handling
Add err goto label where we can jump to from all error conditions.
STALL request on all errors.  Reset position on all errors.

Normal request processing is not in a else branch any more, so this code
is reintended, there are no code changes in that part of the code
though.

898248a329 xhci: drop ER_FULL_HACK workaround
The nec/renesas driver problems have finally been debugged and root
caused, see commit "7da76e1 xhci: fix event queue IRQ handling".

It's pretty clear now that
 (a) The whole "driver can't handle ring full" story is most likely
     wrong.
 (b) The ER_FULL_HACK workaround based on the false assumtion doesn't
     much.  It avoids the driver crashing (without commit 7da76e1), but
     it doesn't make usb work.
 (c) With 7da76e1 applied it doesn't trigger any more.

So, lets kill it.  Or, to be exact, lets almost kill it.  Some data
fields are kept unused in the state struct, for live migration backward
compatibility.

7da76e12cc xhci: fix event queue IRQ handling
The qemu xhci emulation doesn't handle the ERDP_EHB flag correctly.

When the host adapter queues a new event the ERDP_EHB flag is set.  The
flag is cleared (via w1c) by the guest when it updates the ERDP (event
ring dequeue pointer) register to notify the host adapter which events
it has fetched.

An IRQ must be raised in case the ERDP_EHB flag flips from clear to set.
If the flag is set already (which implies there are events queued up
which are not yet processed by the guest) xhci must *not* raise a IRQ.

Qemu got that wrong and raised an IRQ on every event, thereby generating
spurious interrupts in case we've queued events faster than the guest
processed them.  This patch fixes that.

With that change in place we also have to check ERDP updates, to see
whenever the guest has fetched all queued events.  In case there are
still pending events set ERDP_EHB and raise an IRQ again, to make sure
the events don't linger unseen forever.

The linux kernel driver and the microsoft windows driver (shipped with
win8+) can deal with the spurious interrupts without problems.  The
renesas windows driver (v2.1.39) which can be used on older windows
versions is quite upset though.  It does spurious ERDP updates now and
then (not every time, seems we must hit a race window for this to
happen), which in turn makes the qemu xhci emulation think the event
ring is full.  Things go south from here ...

tl;dr: This is the "fix xhci on win7" patch.

0cd089e937 hw/usb/dev-hid: Improve guest compatibility of usb-tablet
1. Set bInterfaceProtocol to 0x00 for usb-tablet. This should be
    non-zero for boot protocol devices only, which the usb-tablet is not.
 2. Set the usb-tablet's usage to "mouse" in the report descriptor.

The boot protocol of 0x02 specifically confused OS X/macOS' HID driver
stack, causing it to generate additional bogus HID events with relative
motion in addition to the tablet's absolute coordinate events.

Absolute pointing devices with HID Report Descriptor usage of 0x01
(pointing) are treated by the macOS HID driver as analog sticks, and
absolute coordinates are not directly translated to absolute mouse
cursor positions. Changing it to 0x02 (mouse) fixes the problem, and
does not have any adverse effect in other operating systems and
windowing systems. (VMWare does the same thing.)

5459ef3bff ppc patch queue 2017-02-02
This obsoletes ppc-for-2.9-20170112, which had a MacOS build bug.
 
 This is a long overdue ppc pull request for qemu-2.9.  It's been a
 long time coming due to some holidays and inconveniently timed
 problems with testing.  So, there's a lot in here:
 
     * More POWER9 instruction implementations for TCG
     * The simpler parts of my CPU compatibility mode cleanup
         * This changes behaviour to prefer compatibility modes over
           "raW" mode for new machine type versions
     * New "40p" machine type which is essentially a modernized and
       cleaned up "prep".  The intention is that it will replace "prep"
       once it has some more testing and polish.
     * Add pseries-2.9 machine type
     * Implement H_SIGNAL_SYS_RESET hypercall
     * Consolidate the two alternate CPU init paths in pseries by
       making it always go through CPU core objects to initialize CPU
     * A number of bugfixes and cleanups
     * Stop the guest timebase when the guest is stopped under KVM.
       This makes the guest system clock also stop when paused, which
       matches the x86 behaviour.
     * Some preliminary cleanups leading towards implementation of the
       POWER9 MMU.
 
 There are also some changes not strictly related to ppc code, but for
 its benefit:
 
     * Limit the pxi-expander-bridge (PXB) device to x86 guests only
       (it's essentially a hack to work around historical x86
       limitations)
     * Some additions to the 128-bit math in host_utils, necessary for
       some of the new instructions.
     * Revise a number of qtests and enable them for ppc

ee640c625e pci: Convert msix_init() to Error and fix callers
msix_init() reports errors with error_report(), which is wrong when
it's used in realize().  The same issue was fixed for msi_init() in
commit 1108b2f. In order to make the API change as small as possible,
leave the return value check to later patch.

For some devices(like e1000e, vmxnet3, nvme) who won't fail because of
msix_init's failure, suppress the error report by passing NULL error
object.

Bonus: add comment for msix_init.

7f4076c1bb trace: clean up trace-events files
There are a number of unused trace events that
scripts/cleanup-trace-events.pl finds.  The "hw/vfio/pci-quirks.c"
filename was typoed and "qapi/qapi-visit-core.c" was missing the qapi/
directory prefix.

b99260ebbb hw/ppc/spapr: Fix boot path of usb-host storage devices
When passing through an USB storage device to a pseries guest, it
is currently not possible to automatically boot from the device
if the "bootindex" property has been specified, too (e.g. when using
"-device nec-usb-xhci -device usb-host,hostbus=1,hostaddr=2,bootindex=0"
at the command line). The problem is that QEMU builds a device tree path
like "/pci@800000020000000/usb@0/usb-host@1" and passes it to SLOF
in the /chosen/qemu,boot-list property. SLOF, however, probes the
USB device, recognizes that it is a storage device and thus changes
its name to "storage", and additionally adds a child node for the
SCSI LUN, so the correct boot path in SLOF is something like
"/pci@800000020000000/usb@0/storage@1/disk@101000000000000" instead.
So when we detect an USB mass storage device with SCSI interface,
we've got to adjust the firmware boot-device path properly that
SLOF can automatically boot from the device.

20daa90a20 PCI/migration merge vmstate_pci_device and vmstate_pcie_device
The vmstate_pci_device and vmstate_pcie_devices differ
just in the size of one buffer; combine the two using a _TEST
macro.

I think this is safe as long as everywhere which currently
uses either of these two uses the right type.

One thing that concerns me is that some places use pci_device_load/save
which does some irq mangling, but others just use the VMSTATE_PCI_DEVICE
macro - how are they getting the same irq mangling?

This passes a smoke test migrate of:
./x86_64-softmmu/qemu-system-x86_64 -M pc,accel=kvm -m 1024
./littlefed20.img -device e1000e -device virtio-net -device
e1000 -device virtio-rng -device megasas -device megasas-gen2 -device
ioh3420 -device nec-usb-xhci

to an unmodified qemu.

"--only-migratable" was specified, all unmigratable devices will
