This changes the way the ohci emulation handles a Transfer Descriptor
with "Buffer End" set to "Current Buffer Pointer" - 1, specifically
in the case of a zero-length packet.
The OHCI spec 4.3.1.2 Table 4-2 specifies td.cbp to be zero for a
zero-length packet. Peter Maydell tracked down commit 1328fe0c32
(hw: usb: hcd-ohci: check len and frame_number variables) where qemu
started checking this according to the spec.
What this patch does is loosen the qemu ohci implementation to allow a
zero-length packet if td.be (Buffer End) is set to td.cbp - 1, and with a
non-zero td.cbp value.
The spec is unclear whether this is valid or not -- it is not the
clearly documented way to send a zero length TD (which is CBP=BE=0),
but it isn't specifically forbidden. Actual hw seems to be ok with it.
Does any OS rely on this behavior? There have been no reports to
qemu-devel of this problem.
This is attempting to have qemu behave like actual hardware,
but this is just a minor change.
With a tiny OS[1] that boots and executes a test, the issue can be seen:
* OS that sends USB requests to a USB mass storage device
but sends td.cbp = td.be + 1
* qemu 4.2
* qemu HEAD (4e66a0854)
* Actual OHCI controller (hardware)
Command line:
qemu-system-x86_64 -m 20 \
-device pci-ohci,id=ohci \
-drive if=none,format=raw,id=d,file=testmbr.raw \
-device usb-storage,bus=ohci.0,drive=d \
--trace "usb_*" --trace "ohci_*" -D qemu.log
Results are:
qemu 4.2 | qemu HEAD | actual HW
-----------+------------+-----------
works fine | ohci_die() | works fine
Tip: if the flags "-serial pty -serial stdio" are added to the command line
the test will output USB requests like this:
Testing qemu HEAD:

This commit modifies the dwc2_hsotg_read() and dwc2_hsotg_write() functions
to handle invalid address access gracefully. Instead of using
g_assert_not_reached(), which causes the program to abort, the functions
now log an error message and return a default value for reads or do
nothing for writes.
This change prevents the program from aborting and provides clear log
messages indicating when an invalid memory address is accessed.

All that the registration does is record the existence of the backend

This makes it possible to remove them from the build without introducing

Commit 30896374 started to pass the full BlockConf from usb-storage to
scsi-disk, while previously only a few select properties would be
forwarded. This enables the user to set more properties, e.g. the block
size, that are actually taking effect.
However, now the calls to blkconf_apply_backend_options() and
blkconf_blocksizes() in usb_msd_storage_realize() that modify some of
these properties take effect, too, instead of being silently ignored.
This means at least that the block sizes get an unconditional default of
512 bytes before the configuration is passed to scsi-disk.
Before commit 30896374, the property wouldn't be set for scsi-disk and
therefore the device dependent defaults would apply - 512 for scsi-hd,
but 2048 for scsi-cd. The latter default has now become 512, too, which
makes at least Windows 11 installation fail when installing from
usb-storage.
Fix this by simply not calling these functions any more in usb-storage
and passing BlockConf on unmodified (except for the BlockBackend). The
same functions are called by the SCSI code anyway and it sets the right
defaults for the actual media type.
Fixes: 3089637461 ('scsi: Don't ignore most usb-storage properties')

This fixes the invalid bInterfaceProtocol value 0x04 in the USB audio
AudioControl descriptors. It should be zero. While Linux and Windows
forgive this error, macOS 14 Sonoma does not. The usb-audio device does
not appear in macOS sound settings even though the device is recognized
and shows up in USB system information. According to the USB audio class
specs 1.0-4.0, valid values are 0x00, 0x20, 0x30 and 0x40. (Note also
that Linux prints the warning "unknown interface protocol 0x4, assuming
v1", but then proceeds as if the value was zero.)
This also fixes the invalid wTotalLength value in the multi-channel
setup AudioControl interface header descriptor (used when multi=on
and out.mixing-engine off). The combined length of all the descriptors
there add up to 0x37, not 0x38. In Linux, "lsusb -D ..." displays
incomplete descriptor information when this length is incorrect.

Since Windows text files use CRLFs for all \n, the Windows version of QEMU
inserts a CR in the PCAP stream when a LF is encountered when using USB PCAP
files. This is due to the fact that the PCAP file is opened as TEXT instead
of BINARY.
To show an example, when using a very common protocol to USB disks, the BBB
protocol uses a 10-byte command packet. For example, the READ_CAPACITY(10)
command will have a command block length of 10 (0xA). When this 10-byte
command (part of the 31-byte CBW) is placed into the PCAP file, the Windows
file manager inserts a 0xD before the 0xA, turning the 31-byte CBW into a
32-byte CBW.
Actual CBW:
0040 55 53 42 43 01 00 00 00 08 00 00 00 80 00 0a 25 USBC...........%
0050 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ...............

I believe simply opening the PCAP file as BINARY instead of TEXT will fix

usb-storage is for the most part just a wrapper around an internally
created scsi-disk device. It uses DEFINE_BLOCK_PROPERTIES() to offer all
of the usual block device properties to the user, but then only forwards
a few select properties to the internal device while the rest is
silently ignored.
This changes scsi_bus_legacy_add_drive() to accept a whole BlockConf
instead of some individual values inside of it so that usb-storage can
now pass the whole configuration to the internal scsi-disk. This enables
the remaining block device properties, e.g. logical/physical_block_size
or discard_granularity.

When a vm transitions from running to suspended, runstate notifiers are
not called, so the notifiers still think the vm is running. Hence, when
we call vm_start to restore the suspended state, we call vm_state_notify
with running=1. However, some notifiers check for RUN_STATE_RUNNING.
They must check the running boolean instead.
No functional change.

This variable is about the host OS, not the target. It is used a lot
more since the Meson conversion, but the original sin dates back to 2003.

only CONFIG_LINUX has substantial use. Convert them all to if...endif.

This device is part of a superio/ISA bridge chip and IRQs from it are
routed to an ISA interrupt. Use via_isa_set_irq() function to implement
this in a vt82c686-uhci-pci specific irq handler.
This reverts commit 422a6e8075.

Recently MemReentrancyGuard was added to DeviceState to record that the
device is engaging in I/O. The network device backend needs to update it
when delivering a packet to a device.
In preparation for such a change, add MemReentrancyGuard * as a
parameter of qemu_new_nic().

Starting from audio_driver_init, propagate errors via Error ** so that
audio_init_audiodevs can simply pass &error_fatal, and AUD_register_card

In xhci_get_port_bandwidth(), we use a variable-length array to
construct the buffer to send back to the guest. Avoid the VLA
by using dma_memory_set() to directly request the memory system
to fill the guest memory with a string of '80's.
The codebase has very few VLAs, and if we can get rid of them all we
can make the compiler error on new additions. This is a defensive
measure against security bugs where an on-stack dynamic allocation
isn't correctly size-checked (e.g. CVE-2021-3527).

GLib recommend to use G_SOURCE_REMOVE / G_SOURCE_CONTINUE
for GSourceFunc callbacks. Our FEWatchFunc is a GSourceFunc
returning such value. Use such definitions which are

Apache license is considered by some to be not compatible
with GPLv2+. Since QEMU as combined work is GPLv2-only,
these two files should be made compatible.

It is useful to extend the number of available PCIe devices to KVM guests
for passthrough scenarios and also to expose these models to a different
(big endian) architecture. Introduce a new config PCIE_DEVICES to select
models, Intel Ethernet adapters and one USB controller. These devices all
support MSI-X which is a requirement on s390x as legacy INTx are not
supported.

We use the user_ss[] array to hold the user emulation sources,
and the softmmu_ss[] array to hold the system emulation ones.
Hold the latter in the 'system_ss[]' array for parity with user
emulation.
Mechanical change doing:
$ sed -i -e s/softmmu_ss/system_ss/g $(git grep -l softmmu_ss)

When the OHCI controller's framenumber is incremented, HccaPad1 register
should be set to zero (Ref OHCI Spec 4.4)
ReactOS uses hccaPad1 to determine if the OHCI hardware is running,
consequently it fails this check in current qemu master.
