13787d59cf usb: Use angle brackets for cacard include directive
This is a library header, so angle brackets are more appropriate; also
move the line to before QEMU headers, as is recommended in HACKING.

The object_unparent() here is not necessary anymore since commit

fails"), so let's remove it now.

44b1ff319c migration: pre_save return int
Modify the pre_save method on VMStateDescription to return an int
rather than void so that it potentially can fail.

Changed zillions of devices to make them return 0; the only
case I've made it return non-0 is hw/intc/s390_flic_kvm.c that already
had an error_report/return case.

Note: If you add an error exit in your pre_save you must emit
an error_report to say why.

2ab4b13563 Convert single line fprintf(.../n) to warn_report()
Convert all the single line uses of fprintf(stderr, "warning:"..."\n"...
to use warn_report() instead. This helps standardise on a single
method of printing warnings to the user.

All of the warnings were changed using this command:
  find ./* -type f -exec sed -i \
    's|fprintf(.*".*warning[,:] \(.*\)\\n"\(.*\));|warn_report("\1"\2);|Ig' \
    {} +

Some of the lines were manually edited to reduce the line length to below
80 charecters.

The #include lines were manually updated to allow the code to compile.

Nowdays we use libusb for usb-host, so we don't have different code

HOST_USB variable, we can just write things directly into the Makefile

6100dda70d xhci: Avoid DMA when ERSTBA is set to zero
The existing XHCI code reads the Event Ring Segment Table Base Address
Register (ERSTBA) every time when it is changed. However zero is its
default state so one would think that zero there means it is not in use.

This adds a check for ERSTBA in addition to the existing check for
the Event Ring Segment Table Size Register (ERSTSZ).

8908eb1a4a trace-events: fix code style: print 0x before hex numbers
The only exception are groups of numers separated by symbols
'.', ' ', ':', '/', like 'ab.09.7d'.

This patch is made by the following:

> find . -name trace-events | xargs python script.py

where script.py is the following python script:
=========================
 #!/usr/bin/env python

import sys
import re
import fileinput

rhex = '%[-+ *.0-9]*(?:[hljztL]|ll|hh)?(?:x|X|"\s*PRI[xX][^"]*"?)'
rgroup = re.compile('((?:' + rhex + '[.:/ ])+' + rhex + ')')
rbad = re.compile('(?<!0x)' + rhex)

files = sys.argv[1:]

for fname in files:
    for line in fileinput.input(fname, inplace=True):
        arr = re.split(rgroup, line)
        for i in range(0, len(arr), 2):
            arr[i] = re.sub(rbad, '0x\g<0>', arr[i])

        sys.stdout.write(''.join(arr))

d87aa13803 trace: add trace_event_get_state_backends()
Code that checks dstate is unaware of SystemTap and LTTng UST dstate, so
the following trace event will not fire when solely enabled by SystemTap
or LTTng UST:

  if (trace_event_get_state(TRACE_MY_EVENT)) {
      str = g_strdup_printf("Expensive string to generate ...",
                            ...);
      trace_my_event(str);
      g_free(str);
  }

Add trace_event_get_state_backends() to fetch backend dstate.  Those
backends that use QEMU dstate fetch it as part of
generate_h_backend_dstate().

Update existing trace_event_get_state() callers to use
trace_event_get_state_backends() instead.

121829cb21 usb: Fix build with newer gcc
gcc 7 is pickier about our sources:

hw/usb/bus.c: In function ‘usb_port_location’:
hw/usb/bus.c:410:66: error: ‘%d’ directive output may be truncated writing between 1 and 11 bytes into a region of size between 0 and 15 [-Werror=format-truncation=]
         snprintf(downstream->path, sizeof(downstream->path), "%s.%d",
                                                                  ^~
hw/usb/bus.c:410:9: note: ‘snprintf’ output between 3 and 28 bytes into a destination of size 16
         snprintf(downstream->path, sizeof(downstream->path), "%s.%d",
         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
                  upstream->path, portnr);
                  ~~~~~~~~~~~~~~~~~~~~~~~

But we know that there are at most 5 levels of USB hubs, with at
most two digits per level; that plus the separating dots means we
use at most 15 bytes (including trailing NUL) of our 16-byte field.
Adding an assertion to show gcc that we checked for truncation is
enough to shut up the false-positive warning.

Inspired by an idea by Dr. David Alan Gilbert <dgilbert@redhat.com>.

3dc6f86936 Convert error_report() to warn_report()
Convert all uses of error_report("warning:"... to use warn_report()
instead. This helps standardise on a single method of printing warnings
to the user.

All of the warnings were changed using these two commands:
    find ./* -type f -exec sed -i \
      's|error_report(".*warning[,:] |warn_report("|Ig' {} +

Indentation fixed up manually afterwards.

The test-qdev-global-props test case was manually updated to ensure that
this patch passes make check (as the test cases are case sensitive).

d2164ad35c vmstate: error hint for failed equal checks
In some cases a failing VMSTATE_*_EQUAL does not mean we detected a bug,
but it's actually the best we can do. Especially in these cases a verbose
error message is required.

Let's introduce infrastructure for specifying a error hint to be used if
equal check fails. Let's do this by adding a parameter to the _EQUAL
macros called _err_hint. Also change all current users to pass NULL as
last parameter so nothing changes for them.

896b6757f9 usb-host: support devices with sparse/non-sequential USB interfaces
Some USB devices have sparse interface numbering which is not able to be
passthroughed.
For example, the Sierra Wireless MC7455/MC7430:

  # lsusb  -D /dev/bus/usb/003/003 | egrep '1199|9071|bNumInterfaces|bInterfaceNumber'
  Device: ID 1199:9071 Sierra Wireless, Inc.
    idVendor           0x1199 Sierra Wireless, Inc.
    idProduct          0x9071
      bNumInterfaces          5
        bInterfaceNumber        0
        bInterfaceNumber        2
        bInterfaceNumber        3
        bInterfaceNumber        8
        bInterfaceNumber       10

In this case, the interface numbers are 0, 2, 3, 8, 10 and not the
0, 1, 2, 3, 4 that QEMU tries to claim.

This change allows sparse USB interface numbering.
Instead of only claiming the interfaces in the range reported by the USB
device through bNumInterfaces, QEMU attempts to claim all possible
interfaces.

v2 to fix broken v1 patch formatting.
v3 to fix indentation.

The dequeue pointer should only be updated in case the transfer
is actually completed.  If we update it for inflight transfers
we will not pick them up again after migration, which easily
triggers with HID devices as they typically have a pending
transfer, waiting for user input to happen.

1ce2610c10 char: make chr_fe_deinit() optionaly delete backend
This simplifies removing a backend for a frontend user (no need to
retrieve the associated driver and separate delete call etc).

NB: many frontends have questionable handling of ending a chardev. They
should probably delete the backend to prevent broken reusage.

3bfecee2cb ehci: fix frame timer invocation.
ehci registers ehci_frame_timer as both timer and bottom half, which
turned out to be a bad idea as it can be called as bottom half then
while it is running as timer, and it isn't prepared to handle recursive
calls.

Change the timer func to just schedule the bottom half to avoid this.

PORT_STAT_C_SUSPEND should be set even on host-initiated wake-up,

Side note, since PORT_ENABLE looks similar and might appear to
have the same issue: According to 11.24.2.7.2.2 C_PORT_ENABLE:

  "This bit is set when the PORT_ENABLE bit changes from one to
  zero as a result of a Port Error condition (see Section 11.8.1).
  This bit is not set on any other changes to PORT_ENABLE."

aa612b364e hw/usb/dev-serial: Do not try to set vendorid or productid properties
When starting QEMU with the legacy USB serial device like this:

 qemu-system-x86_64 -usbdevice serial:vendorid=0x1234:stdio

it currently aborts since the vendorid property does not exist
anymore (it has been removed by commit f29783f72e):

 Unexpected error in object_property_find() at qemu/qom/object.c:1008:
 qemu-system-x86_64: -usbdevice serial:vendorid=0x1234:stdio: Property
                     '.vendorid' not found
 Aborted (core dumped)

Fix this crash by issuing a more friendly error message instead
(and simplify the code also a little bit this way).

99f9aeba5d xhci: relax link check
The strict td link limit added by commit "05f43d4 xhci: limit the
number of link trbs we are willing to process" causes problems with
Windows guests. Let's raise the limit.

This change is analogous to:

66849dcfbe usb-hub: clear PORT_STAT_SUSPEND on wakeup
The spec says:

  Suspend: (PORT_SUSPEND) This field indicates whether or not the device
  on this port is suspended. Setting this field causes the device to
  suspend by not propagating bus traffic downstream. This field may be
  reset by a request or by resume signaling from the device attached to
  the port.

I can't find any specific statement like "the PORT_SUSPEND field is reset
automatically on remote wakeup", but without this patch, the only way to
reset it is via the ClearPortFeature request so the ".. or by resume
signaling from the device" clause is clearly not implemented on the remote
wakeup path.

The default xhci Windows driver does not issue the ClearPortFeature request
and suspended devices attached to a hub don't properly get out of the
suspended state. Interestingly, the default uhci Windows driver *does*
issue the ClearPortFeature request and does not exhibit this problem.

    --macro-file scripts/cocci-macro-file.h --dir . --in-place
then touched up manually to fix a couple of '?:' back to original

243afe858b xhci: flush dequeue pointer to endpoint context
When done processing a endpoint ring we must update the dequeue pointer
in the endpoint context in guest memory.  This is needed to make sure
the guest has a correct view of things and also to make live migration
work properly, because xhci post_load restores alot of the state from
xhci data structures in guest memory.

Add xhci_set_ep_state() call to do that.

The recursive calls stopped by commit
ddb603ab6c had the (unintentional) side
effect to hiding this bug.  xhci_set_ep_state() was called before
processing, to set the state to running, which updated the dequeue
pointer too.

7562f90707 migrate: Introduce a 'dc->vmsd' check to avoid segfault for --only-migratable
Commit a3a3d8c7 introduced a segfault bug while checking for
'dc->vmsd->unmigratable' which caused QEMU to crash when trying to add
devices which do no set their 'dc->vmsd' yet while initialization.
Place a 'dc->vmsd' check prior to it so that we do not segfault for
such devices.

NOTE: This doesn't compromise the functioning of --only-migratable
option as all the unmigratable devices do set their 'dc->vmsd'.

Introduce a new function check_migratable() and move the
only_migratable check inside it, also use stubs to avoid user-mode qemu
build failures.

Also move the intrs and slots properties.  Wasn't a great idea to
make them configurable in the first place, nobody needs this.

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.)

     * Consolidate the two alternate CPU init paths in pseries by

     * A number of bugfixes and cleanups
     * Stop the guest timebase when the guest is stopped under KVM.

       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

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.

20729dbd01 hcd-xhci: check & correct param before using it
usb_xhci_realize() corrects invalid values of property "intrs"
automatically, but the uncorrected value is passed to msi_init(),
which chokes on invalid values.  Delay that until after the
correction.

Resources allocated by usb_xhci_init() are leaked when msi_init()
fails.  Fix by calling it after msi_init().

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.
