[ Upstream commit bce2b0539933e485d22d6f6f076c0fcd6f185c4c ]
In idmouse_create_image, if any ftip_command fails, it will
go to the reset label. However, this leads to the data in
bulk_in_buffer[HEADER..IMGSIZE] uninitialized. And the check
for valid image incurs an uninitialized dereference.
Fix this by moving the check before reset label since this
check only be valid if the data after bulk_in_buffer[HEADER]
has concrete data.
Note that this is found by KMSAN, so only kernel compilation
is tested.

[ Upstream commit ad5dbfc123e6ffbbde194e2a4603323e09f741ee ]
This reverts commit 86d92f5465958752481269348d474414dccb1552,
which fix the timeout issue for "Samsung Fit Flash".
But the commit affects not only "Samsung Fit Flash" but also other usb
storages that use the same controller and causes severe performance
regression.
# hdparm -t /dev/sda (without the quirk)
Timing buffered disk reads: 622 MB in 3.01 seconds = 206.66 MB/sec
# hdparm -t /dev/sda (with the quirk)
Timing buffered disk reads: 220 MB in 3.00 seconds = 73.32 MB/sec
The commit author mentioned that "Issue was reproduced after device has
bad block", so this quirk should be applied when we have the timeout
issue with a device that has bad blocks.
We revert the commit so that we apply this quirk by adding kernel
paramters using a bootloader or other ways when we really need it,
without the performance regression with devices that don't have the
issue.

When opts->pnp_string is changed with configfs, new memory is allocated for
the string. It does not, however, update dev->pnp_string, even though the
memory is freed. When rquesting the string, the host then gets old or
corrupted data rather than the new string. The ieee 1284 id string should
be allowed to change while the device is connected.
The bug was introduced in commit fdc01cc286be ("usb: gadget: printer:

char[] to a char*.

commit 37d49519b41405b08748392c6a7f193d9f77ecd2 upstream.
The Lenovo OneLink+ Dock contains two VL812 USB3.0 controllers:
17ef:1018 upstream
17ef:1019 downstream
These hubs suffer from two separate problems:
1) After the host system was suspended and woken up, the hubs appear to
be in a random state. Some downstream ports (both internal to the
built-in audio and network controllers, and external to USB sockets)
may no longer be functional. The exact list of disabled ports (if
any) changes from wakeup to wakeup. Ports remain in that state until
the dock is power-cycled, or until the laptop is rebooted.
Wakeup sources connected to the hubs (keyboard, WoL on the integrated
gigabit controller) will wake the system up from suspend, but they
may no longer work after wakeup (and in that case will no longer work
as wakeup source in a subsequent suspend-wakeup cycle).
This issue appears in the logs with messages such as:
usb 1-6.1-port4: cannot disable (err = -71)
usb 1-6-port2: cannot disable (err = -71)
usb 1-6.1: clear tt 1 (80c0) error -71
usb 1-6-port4: cannot disable (err = -71)
usb 1-6.4: PM: dpm_run_callback(): usb_dev_resume+0x0/0x10 [usbcore] returns -71

usb 1-6.1-port1: cannot disable (err = -71)

usb 1-6.1-port1: Cannot enable. Maybe the USB cable is bad?
usb 1-6.1-port1: cannot disable (err = -71)
2) Some USB devices cannot be enumerated properly. So far I have only
seen the issue with USB 3.0 devices. The same devices work without
problem directly connected to the host system, to other systems or to
other hubs (even when those hubs are connected to the OneLink+ dock).
One very reliable reproducer is this USB 3.0 HDD enclosure:
152d:9561 JMicron Technology Corp. / JMicron USA Technology Corp. Mobius
I have seen it happen sporadically with other USB 3.0 enclosures,
with controllers from different manufacturers, all self-powered.
Typical messages in the logs:
xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command
xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command
usb 2-1.4: device not accepting address 6, error -62
xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command
xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command
usb 2-1.4: device not accepting address 7, error -62
usb 2-1-port4: attempt power cycle
xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command

xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command
usb 2-1.4: device not accepting address 9, error -62
usb 2-1-port4: unable to enumerate USB device
Through trial and error, I found that the USB_QUIRK_RESET_RESUME solved
the second issue. Further testing then uncovered the first issue. Test
results are summarized in this table:
=======================================================================================
Settings USB2 hotplug USB3 hotplug State after waking up
---------------------------------------------------------------------------------------
power/control=auto works fails broken
usbcore.autosuspend=-1 works works broken
OR power/control=on
power/control=auto works (1) works (1) works
and USB_QUIRK_RESET_RESUME
power/control=on works works works
and USB_QUIRK_RESET_RESUME
HUB_QUIRK_DISABLE_AUTOSUSPEND works works works
and USB_QUIRK_RESET_RESUME
=======================================================================================
In those results, the power/control settings are applied to both hubs,
both on the USB2 and USB3 side, before each test.
From those results, USB_QUIRK_RESET_RESUME is required to reset the hubs
properly after a suspend-wakeup cycle, and the hubs must not autosuspend
to work around the USB3 issue.
A secondary effect of USB_QUIRK_RESET_RESUME is to prevent the hubs'
upstream links from suspending (the downstream ports can still suspend).
This secondary effect is used in results (1). It is enough to solve the
USB3 problem.
Setting USB_QUIRK_RESET_RESUME on those hubs is the smallest patch that
solves both issues.
Prior to creating this patch, I have used the USB_QUIRK_RESET_RESUME via
the kernel command line for over a year without noticing any side
effect.
Thanks to Oliver Neukum @Suse for explanations of the operations of
USB_QUIRK_RESET_RESUME, and requesting more testing.

ISO OUT endpoint is enabled during queuing first usb request
in transfer ring and disabled when TRBERR is reported by controller.
After TRBERR and before next transfer added to TR driver must again
reenable endpoint but does not.
To solve this issue during processing TRBERR event driver must
set the flag EP_UPDATE_EP_TRBADDR in priv_ep->flags field.

The TRB_SMM flag indicates that DMA has completed the TD service with
this TRB. Usually it’s a last TRB in TD. In case of ISOC transfer for
bInterval > 1 each ISOC transfer contains more than one TD associated
with usb request (one TD per ITP). In such case the TRB_SMM flag will
be set in every TD and driver will recognize the end of transfer after
processing the first TD with TRB_SMM. In result driver stops updating
request->actual and returns incorrect actual length.
To fix this issue driver additionally must check TRB_CHAIN which is not
used for isochronous transfers.

The Lenovo OneLink+ Dock contains two VL812 USB3.0 controllers:
17ef:1018 upstream
17ef:1019 downstream
Those two controllers both have problems with some USB3.0 devices,
particularly self-powered ones. Typical error messages include:
Timeout while waiting for setup device command
device not accepting address X, error -62
unable to enumerate USB device
By process of elimination the controllers themselves were identified as
the cause of the problem. Through trial and error the issue was solved
by using USB_QUIRK_RESET_RESUME for both chips.

Currently xhci-mtk needs software-managed bandwidth allocation for
periodic endpoints, it allocates the microframe index for the first
start-split packet for each endpoint. As this index allocation logic
should avoid the conflicts with other full/low-speed periodic endpoints,
it uses the worst case byte budgets on high-speed bus bandwidth
For example, for an isochronos IN endpoint with 192 bytes budget,
it will consume the whole 4 u-frames(188 * 4) while the actual
full-speed bus budget should be just 192bytes.
This patch changes the low/full-speed bandwidth allocation logic
to use "approximate" best case budget for lower speed bandwidth
management. For the same endpoint from the above example, the
approximate best case budget is now reduced to (188 * 2) bytes.
Without this patch, many usb audio headsets with 3 interfaces
(audio input, audio output, and HID) cannot be configured
on xhci-mtk.

In USB2 Spec:
"11.18.5 TT Response Generation
In general, there will be two (or more) complete-split
transactions scheduled for a periodic endpoint.
However, for interrupt endpoints, the maximum size of
the full-/low-speed transaction guarantees that it can
never require more than two complete-split transactions.
Two complete-split transactions are only required
when the transaction spans a microframe boundary."
Due to the maxp is 64, and less then 188 (at most in one
microframe), seems never span boundary, so use only one CS
for FS/LS interrupt transfer, this will save some bandwidth.

If the GEVNTCOUNT indicates events in the event buffer, the driver needs
to acknowledge them before the controller can halt. Simply let the
interrupt handler acknowledges the remaining event generated by the
controller while polling for DSTS.DEVCTLHLT. This avoids disabling irq
and taking care of race condition between the interrupt handlers and
pullup().

There is a race present where the DWC3 runtime resume runs in parallel
to the UDC unbind sequence. This will eventually lead to a possible
scenario where we are enabling the run/stop bit, without a valid
composition defined.
Thread#1 (handling UDC unbind):
usb_gadget_remove_driver()
-->usb_gadget_disconnect()
-->dwc3_gadget_pullup(0)
--> continue UDC unbind sequence
-->Thread#2 is running in parallel here
Thread#2 (handing next cable connect)
__dwc3_set_mode()
-->pm_runtime_get_sync()
-->dwc3_gadget_resume()
-->dwc->gadget_driver is NOT NULL yet
-->dwc3_gadget_run_stop(1)
--> _dwc3gadget_start()
...
Fix this by tracking the pullup disable routine, and avoiding resuming
of the DWC3 gadget. Once the UDC is re-binded, that will trigger the
pullup enable routine, which would handle enabling the DWC3 gadget.

This adds the necessary ACPI ID for Intel Meteor Lake
IOM devices.
The callback function is_memory() is modified so that it
also checks if the resource descriptor passed to it is a
memory type "Address Space Resource Descriptor".
On Intel Meteor Lake the ACPI memory resource is not
described using the "32-bit Memory Range Descriptor" because
the memory is outside of the 32-bit address space. The
memory resource is described using the "Address Space
Resource Descriptor" instead.
Intel Meteor Lake is the first platform to describe the
memory resource for this device with Address Space Resource
Descriptor, but it most likely will not be the last.
Therefore the change to the is_memory() callback function
is made generic.
