d755cb9696 hw/usb/dev-uas: Report command additional adb length as unsupported
We are not ready to handle additional CDB data.

If a guest sends a packet with such additional data,
report the command parameter as not supported.

Specify a size (of 1 byte) for the add_cdb member we
are not using, to fix the following warning:

  usb/dev-uas.c:157:31: error: field 'status' with variable sized type 'uas_iu' not at the end of a struct or class is a GNU extension [-Werror,-Wgnu-variable-sized-type-not-at-end]

96b66e5575 hw/usb/hcd-xhci: Fix extraneous format-truncation error on 32-bit hosts
For some reason the assert() added in commit ccb799313a

KISS and expand the buffer by 4 bytes to silent the following
error when using GCC 10.2.1 on Fedora 33:

c3585b600b hw/usb: Convert to qdev_realize()
Device code shouldn't mess with QOM property "realized" since we have
proper interfaces (merge commit 6675a653).  Commit 8ddab8dd3d
"usb/hcd-xhci: Split pci wrapper for xhci base model" and commit
f00ff136ee "usb: hcd-xhci-sysbus: Attach xhci to sysbus device"
reintroduced two instances.  Clean them up.  Note that s->xhci is
a (bus-less) TYPE_XHCI device.

a3c27ea034 hw/usb/host-libusb.c: fix build with kernel < 5.0
USBDEVFS_GET_SPEED is used since version 5.2.0 and
202d69a715
resulting in the following build failure with kernel < 5.0:

../hw/usb/host-libusb.c: In function 'usb_host_open':
../hw/usb/host-libusb.c:953:32: error: 'USBDEVFS_GET_SPEED' undeclared (first use in this function); did you mean 'USBDEVFS_GETDRIVER'?
         int rc = ioctl(hostfd, USBDEVFS_GET_SPEED, NULL);
                                ^~~~~~~~~~~~~~~~~~
                                USBDEVFS_GETDRIVER

A tentative was made to fix this build failure with
4969e697c1

However, the assumption that distros with old kernels also have old
libusb is just wrong so also add a check for defined(USBDEVFS_GET_SPEED)

3ddba9a9e9 migration: Replace migration's JSON writer by the general one
Commit 8118f0950f "migration: Append JSON description of migration
stream" needs a JSON writer.  The existing qobject_to_json() wasn't a
good fit, because it requires building a QObject to convert.  Instead,
migration got its very own JSON writer, in commit 190c882ce2 "QJSON:
Add JSON writer".  It tacitly limits numbers to int64_t, and strings
contents to characters that don't need escaping, unlike
qobject_to_json().

The previous commit factored the JSON writer out of qobject_to_json().
Replace migration's JSON writer by it.

6ca2aa5cfb usb: fix kconfig for usb-xhci-sysbus
Remove the "default y" for USB_XHCI_SYSBUS because
sysbus devices are not user creatable; boards that use them will
specify them manually with "imply" or "select" clauses.

It would be nice to keep the ability to remove PCIe and USB from microvm,
since thos can be disabled on the command line and therefore should not
be included if QEMU is configured --without-default-devices.  However
it's too late for 5.2 to figure out a place for the DSDT creation code.

172bc8520d xhci: fix nec-usb-xhci properties
Storing properties directly in XHCIPciState.xhci doesn't work,
the object_initialize_child() call in xhci_instance_init() will
overwrite them.

This changes the defaults for some properties, which in turn breaks
live migration and possibly other things as well.

So add XHCINecState, store properties there, copy them over on
instance init.

e23e7b1259 hw/arm/npcm7xx: Add EHCI and OHCI controllers
The NPCM730 and NPCM750 chips have a single USB host port shared between
a USB 2.0 EHCI host controller and a USB 1.1 OHCI host controller. This
adds support for both of them.

Testing notes:
  * With -device usb-kbd, qemu will automatically insert a full-speed
    hub, and the keyboard becomes controlled by the OHCI controller.
  * With -device usb-kbd,bus=usb-bus.0,port=1, the keyboard is directly
    attached to the port without any hubs, and the device becomes
    controlled by the EHCI controller since it's high speed capable.
  * With -device usb-kbd,bus=usb-bus.0,port=1,usb_version=1, the
    keyboard is directly attached to the port, but it only advertises
    itself as full-speed capable, so it becomes controlled by the OHCI
    controller.

In all cases, the keyboard device enumerates correctly.

ccee80c68d usb/hcd-ehci: Fix error handling on missing device for iTD
The EHCI Host Controller emulation attempt to locate the device
associated with a periodic isochronous transfer description (iTD) and
when this fail the host controller is reset.

But according the EHCI spec 1.0 section 5.15.2.4 Host System
Error, the host controller is supposed to reset itself only when it
failed to communicate with the Host (Operating System), like when
there's an error on the PCI bus. If a transaction fails, there's
nothing in the spec that say to reset the host controller.

This patch rework the error path so that the host controller can keep
working when the OS setup a bogus transaction, it also revert to the
behavior of the EHCI emulation to before commits:
e94682f1fe ("ehci: check device is not NULL before calling usb_ep_get()")
7011baece2 ("usb: remove unnecessary NULL device check from usb_ep_get()")

The issue has been found while trying to passthrough a USB device to a
Windows Server 2012 Xen guest via "usb-ehci", which prevent the USB
device from working in Windows. ("usb-ehci" alone works, windows only
setup this weird periodic iTD to device 127 endpoint 15 when the USB
device is passthrough.)

While servicing OHCI transfer descriptors(TD), ohci_service_iso_td

the TD was already processed once and holds an error code in TD_CC.
It may happen if the TD list has a loop. Add check to avoid an

b42581f5bb util/hexdump: Reorder qemu_hexdump() arguments
qemu_hexdump()'s pointer to the buffer and length of the
buffer are closely related arguments but are widely separated
in the argument list order (also, the format of <stdio.h>
function prototypes is usually to have the FILE* argument
coming first).

Reorder the arguments as "fp, prefix, buf, size" which is
more logical.

67263b33af util/hexdump: Convert to take a void pointer argument
Most uses of qemu_hexdump() do not take an array of char
as input, forcing use of cast. Since we can use this
helper to dump any kind of buffer, use a pointer to void
argument instead.

b15e402fc8 trace-events: Fix attribution of trace points to source
Some trace points are attributed to the wrong source file.  Happens
when we neglect to update trace-events for code motion, or add events
in the wrong place, or misspell the file name.

Clean up with help of scripts/cleanup-trace-events.pl.  Funnies
requiring manual post-processing:

* accel/tcg/cputlb.c trace points are in trace-events.

* block.c and blockdev.c trace points are in block/trace-events.

* hw/block/nvme.c uses the preprocessor to hide its trace point use
  from cleanup-trace-events.pl.

* hw/tpm/tpm_spapr.c uses pseudo trace point tpm_spapr_show_buffer to
  guard debug code.

* include/hw/xen/xen_common.h trace points are in hw/xen/trace-events.

* linux-user/trace-events abbreviates a tedious list of filenames to
  */signal.c.

* net/colo-compare and net/filter-rewriter.c use pseudo trace points
  colo_compare_miscompare and colo_filter_rewriter_debug to guard
  debug code.

db1015e92e Move QOM typedefs and add missing includes
Some typedefs and macros are defined after the type check macros.
This makes it difficult to automatically replace their
definitions with OBJECT_DECLARE_TYPE.

Patch generated using:

 $ ./scripts/codeconverter/converter.py -i \
   --pattern=QOMStructTypedefSplit $(git grep -l '' -- '*.[ch]')

which will split "typdef struct { ... } TypedefName"
declarations.

Followed by:

 $ ./scripts/codeconverter/converter.py -i --pattern=MoveSymbols \
    $(git grep -l '' -- '*.[ch]')

which will:
- move the typedefs and #defines above the type check macros
- add missing #include "qom/object.h" lines if necessary

Store calculated setup_len in a local variable, verify it, and only
write it to the struct (USBDevice->setup_len) in case it passed the

This prevents other code (do_token_{in,out} functions specifically)
from working with invalid USBDevice->setup_len values and overrunning

d7c1523f58 hw/usb: Add U2F device autoscan to passthru mode
This patch adds an autoscan to let u2f-passthru choose the first U2F
device it finds.

The autoscan is performed using libudev with an enumeration of all the
hidraw devices present on the host.

The first device which happens to be a U2F device is taken to do the
passtru.

a983b1135f hw/usb: Add U2F key emulated mode
This patch adds the U2F key emulated mode.

The emulated mode consists of completely emulating the behavior of a
U2F device through software part. Libu2f-emu is used for that.

The emulated mode is associated with a device inheriting from
u2f-key base.

To work, an emulated U2F device must have differents elements which
can be given in different ways. This is detailed in docs/u2f.txt.

The Ephemeral one is the simplest way to configure, it lets the device
generate all the elements it needs for a single use of the lifetime
of the device:

    qemu -usb -device u2f-emulated

For more information about libu2f-emu see this page:
https://github.com/MattGorko/libu2f-emu.

299976b050 hw/usb: Add U2F key passthru mode
This patch adds the U2F key pass-through mode.

The pass-through mode consists of passing all requests made from the
guest to the physical security key connected to the host machine and
vice versa.

In addition, the dedicated pass-through allows to have a U2F security key
shared on several guests which is not possible with a simple host device
assignment pass-through.

The pass-through mode is associated with a device inheriting from
u2f-key base.

To work, it needs the path to a U2F hidraw, obtained from the Qemu
command line, and passed by the user:

    qemu -usb -device u2f-passthru,hidraw=/dev/hidrawX

Autoscan and U2F compatibility checking features are given at the end
of the patch series.

bb014a810b hw/usb: Add U2F key base class implementation
This patch adds the U2F key base class implementation.

The U2F key base mainly takes care of the HID interfacing with guest.
On the one hand, it retrieves the guest U2FHID packets and transmits
them to the variant associated according to the mode: pass-through
or emulated.
On the other hand, it provides the public API used by its variants to
send U2FHID packets to the guest.

243af0225a trace: switch position of headers to what Meson requires
Meson doesn't enjoy the same flexibility we have with Make in choosing
the include path.  In particular the tracing headers are using
$(build_root)/$(<D).

In order to keep the include directives unchanged,
the simplest solution is to generate headers with patterns like
"trace/trace-audio.h" and place forwarding headers in the source tree
such that for example "audio/trace.h" includes "trace/trace-audio.h".

This patch is too ugly to be applied to the Makefiles now.  It's only
a way to separate the changes to the tracing header files from the
Meson rewrite of the tracing logic.

8e67fda2dd xhci: fix valid.max_access_size to access address registers
QEMU XHCI advertises AC64 (64-bit addressing) but doesn't allow
64-bit mode access in "runtime" and "operational" MemoryRegionOps.

Set the max_access_size based on sizeof(dma_addr_t) as AC64 is set.

XHCI specs:
"If the xHC supports 64-bit addressing (AC64 = ‘1’), then software
should write 64-bit registers using only Qword accesses.  If a
system is incapable of issuing Qword accesses, then writes to the
64-bit address fields shall be performed using 2 Dword accesses;
low Dword-first, high-Dword second.  If the xHC supports 32-bit
addressing (AC64 = ‘0’), then the high Dword of registers containing
64-bit address fields are unused and software should write addresses
using only Dword accesses"

The problem has been detected with SLOF, as linux kernel always accesses
registers using 32-bit access even if AC64 is set and revealed by
5d971f9e67 ("memory: Revert "memory: accept mismatching sizes in memory_region_access_valid"")

62a35aaa31 qapi: Use returned bool to check for failure, Coccinelle part
The previous commit enables conversion of

    visit_foo(..., &err);
    if (err) {
        ...
    }

to

    if (!visit_foo(..., errp)) {
        ...
    }

for visitor functions that now return true / false on success / error.

118bfd76c9 qdev: Use returned bool to check for qdev_realize() etc. failure
Convert

Chokes on hw/arm/musicpal.c's lcd_refresh() with the unhelpful error
message "no position information".  Nothing to convert there; skipped.

Fails to convert hw/arm/armsse.c, because Coccinelle gets confused by
ARMSSE being used both as typedef and function-like macro there.
Converted manually.

9bc6bfdf67 qdev: Drop qbus_set_hotplug_handler() parameter @errp
qbus_set_hotplug_handler() is a simple wrapper around
object_property_set_link().

object_property_set_link() fails when the property doesn't exist, is
not settable, or its .check() method fails.  These are all programming
errors here, so passing &error_abort to qbus_set_hotplug_handler() is
appropriate.

Most of its callers do.  Exceptions:

* pcie_cap_slot_init(), shpc_init(), spapr_phb_realize() pass NULL,
  i.e. they ignore errors.

* spapr_machine_init() passes &error_fatal.

* s390_pcihost_realize(), virtio_serial_device_realize(),
  s390_pcihost_plug() pass the error to their callers.  The latter two
  keep going after the error, which looks wrong.

Drop the @errp parameter, and instead pass &error_abort to
object_property_set_link().
