[ Upstream commit fce703a991b7e8c7e1371de95b9abaa832ecf9c3 ]
Deferred probe is an expected return value for fwnode_usb_role_switch_get().
Given that the driver deals with it properly, there's no need to output a
warning that may potentially confuse users.

[ 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.

resume bug
[ Upstream commit 63d7f9810a38102cdb8cad214fac98682081e1a7 ]
When configured in HOST mode, after issuing U3/L2 exit controller fails
to send proper CRC checksum in CRC5 field. Because of this behavior
Transaction Error is generated, resulting in reset and re-enumeration of
usb device attached. Enabling chicken bit 10 of GUCTL1 will correct this
problem.
When this bit is set to '1', the UTMI/ULPI opmode will be changed to
"normal" along with HS terminations, term, and xcvr signals after EOR.
This option is to support certain legacy UTMI/ULPI PHYs.
Added "snps,resume-hs-terminations" quirk to resolved the above issue.

[ Upstream commit 7e271f42a5cc3768cd2622b929ba66859ae21f97 ]
xhci_alloc_stream_info() allocates stream context array for stream_info
->stream_ctx_array with xhci_alloc_stream_ctx(). When some error occurs,
stream_info->stream_ctx_array is not released, which will lead to a
memory leak.
We can fix it by releasing the stream_info->stream_ctx_array with
xhci_free_stream_ctx() on the error path to avoid the potential memory
leak.

[ Upstream commit 9b91a65230784a9ef644b8bdbb82a79ba4ae9456 ]
This patch is changing the simple workqueue in the gadget driver to be
allocated as async_wq with a higher priority. The pump worker, that is
filling the usb requests, will have a higher priority and will not be
scheduled away so often while the video stream is handled. This will
lead to fewer streaming underruns.

[ Upstream commit 24b7ba2f88e04800b54d462f376512e8c41b8a3c ]
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*.
This patch changes dev->pnp_string from a char* to a char** pointing to

This from static analysis. The vla_item() takes a size and adds it to
the total. It has a built in integer overflow check so if it encounters
an integer overflow anywhere then it records the total as SIZE_MAX.
However there is an issue here because the "lang_count*(needed_count+1)"
multiplication can overflow. Technically the "lang_count + 1" addition
could overflow too, but that would be detected and is harmless. Fix
both using the new size_add() and size_mul() functions.

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

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.

commit a15e17acce5aaae54243f55a7349c2225450b9bc upstream.
When building s390 allmodconfig after commit 9b91a6523078 ("usb: gadget:

301 | __write_overflow_field(p_size_field, size);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This points to the memset() in uvc_register_video(). It is clear that
the argument to sizeof() is incorrect, as uvc->vdev (a 'struct
video_device') is being zeroed out but the size of uvc->video (a 'struct
uvc_video') is being used as the third arugment to memset().
pahole shows that prior to commit 9b91a6523078 ("usb: gadget: uvc:
increase worker prio to WQ_HIGHPRI"), 'struct video_device' and
'struct ucv_video' had the same size, meaning that the argument to
sizeof() is incorrect semantically but there is no visible issue:
$ pahole -s build/drivers/usb/gadget/function/f_uvc.o | grep -E "(uvc_video|video_device)\s+"
video_device 1400 4
uvc_video 1400 3
After that change, uvc_video becomes slightly larger, meaning that the
memset() will overwrite by 8 bytes:
$ pahole -s build/drivers/usb/gadget/function/f_uvc.o | grep -E "(uvc_video|video_device)\s+"
video_device 1400 4
uvc_video 1408 3
Fix the arugment to sizeof() so that there is no overwrite.

commit a659daf63d16aa883be42f3f34ff84235c302198 upstream.
Syzbot found an issue in usbmon module, where the user space client can
corrupt the monitor's internal memory, causing the usbmon module to
crash the kernel with segfault, UAF, etc.
The reproducer mmaps the /dev/usbmon memory to user space, and
overwrites it with arbitrary data, which causes all kinds of issues.
Return an -EPERM error from mon_bin_mmap() if the flag VM_WRTIE is set.
Also clear VM_MAYWRITE to make it impossible to change it to writable
later.

commit 415ba26cb73f7d22a892043301b91b57ae54db02 upstream.
Sink only devices do not have any source capabilities, so
the driver should not warn about that. Also DRP (Dual Role
Power) capable devices, such as USB Type-C docking stations,
do not return any source capabilities unless they are
plugged to a power supply themselves.

commit 91062e663b261815573ce00967b1895a99e668df upstream.
On some DWC3 controllers (e.g. Rockchip SoCs), the DWC3 core
doesn't support 64-bit DMA address width. In this case, this
driver should use the default 32-bit mask. Otherwise, the DWC3
controller will break if it runs on above 4GB physical memory
environment.
This patch reads the DWC_USB3_AWIDTH bits of GHWPARAMS0 which
used for the DMA address width, and only configure 64-bit DMA
mask if the DWC_USB3_AWIDTH is 64.

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.

commit 1016fc0c096c92dd0e6e0541daac7a7868169903 upstream.
A recent commit expanding the scope of the udc_lock mutex in the
gadget core managed to cause an obscure and slightly bizarre lockdep
violation. In abbreviated form:

Evidently this was caused by the scope of udc_mutex being too large.
The mutex is only meant to protect udc->driver along with a few other
things. As far as I can tell, there's no reason for the mutex to be
held while the gadget core calls a gadget driver's ->bind or ->unbind
routine, or while a UDC is being started or stopped. (This accounts
for link #1 in the chain above, where the mutex is held while the
dwc2_hsotg_udc is started as part of driver probing.)
Gadget drivers' ->disconnect callbacks are problematic. Even though
usb_gadget_disconnect() will now acquire the udc_mutex, there's a
window in usb_gadget_bind_driver() between the times when the mutex is
released and the ->bind callback is invoked. If a disconnect occurred
during that window, we could call the driver's ->disconnect routine
before its ->bind routine. To prevent this from happening, it will be
necessary to prevent a UDC from connecting while it has no gadget
driver. This should be done already but it doesn't seem to be;
currently usb_gadget_connect() has no check for this. Such a check
will have to be added later.
Some degree of mutual exclusion is required in soft_connect_store(),
which can dereference udc->driver at arbitrary times since it is a
sysfs callback. The solution here is to acquire the gadget's device
lock rather than the udc_mutex. Since the driver core guarantees that
the device lock is always held during driver binding and unbinding,
this will make the accesses in soft_connect_store() mutually exclusive
with any changes to udc->driver.
Lastly, it turns out there is one place which should hold the
udc_mutex but currently does not: The function_show() routine needs
protection while it dereferences udc->driver. The missing lock and
unlock calls are added.

commit 9d4dc16ec71bd6368548e9743223e449b4377fc7 upstream.
During cdrom emulation, the response to read_toc command must contain
the cdrom address as the number of sectors (2048 byte sized blocks)
represented either as an absolute value (when MSF bit is '0') or in
terms of PMin/PSec/PFrame (when MSF bit is set to '1'). Incase of
cdrom, the fsg_lun_open call sets the sector size to 2048 bytes.
When MAC OS sends a read_toc request with MSF set to '1', the
store_cdrom_address assumes that the address being provided is the
LUN size represented in 512 byte sized blocks instead of 2048. It
tries to modify the address further to convert it to 2048 byte sized
blocks and store it in MSF format. This results in data transfer
failures as the cdrom address being provided in the read_toc response
is incorrect.

commit f511aef2ebe5377d4c263842f2e0c0b8e274e8e5 upstream.
On page 362 of the USB3.2 specification (
https://usb.org/sites/default/files/usb_32_20210125.zip),
The 'SuperSpeed Endpoint Companion Descriptor' shall only be returned
by Enhanced SuperSpeed devices that are operating at Gen X speed.
Each endpoint described in an interface is followed by a 'SuperSpeed
Endpoint Companion Descriptor'.
If users use SuperSpeed UDC, host can't recognize the device if endpoint
doesn't have 'SuperSpeed Endpoint Companion Descriptor' followed.
Currently in the uac2 driver code:
1. ss_epout_desc_comp follows ss_epout_desc;
2. ss_epin_fback_desc_comp follows ss_epin_fback_desc;
3. ss_epin_desc_comp follows ss_epin_desc;
4. Only ss_ep_int_desc endpoint doesn't have 'SuperSpeed Endpoint
Companion Descriptor' followed, so we should add it.

commit 6020f480004a80cdad4ae5ee180a231c4f65595b upstream.
This happens when @udev->reset_resume is set to true, when usb resume,
the flow as below:
- hub_resume
- usb_disable_interface
- usb_disable_endpoint
- usb_hcd_disable_endpoint
- xhci_endpoint_disable // it set @ep->hcpriv to NULL
Then when reset usb device, it will drop allocated endpoints,
the flow as below:
- usb_reset_and_verify_device
- usb_hcd_alloc_bandwidth
- xhci_mtk_drop_ep
but @ep->hcpriv is already set to NULL, the bandwidth will be not
released anymore.
Due to the added endponts are stored in hash table, we can drop the check
of @ep->hcpriv.

commit 8b13ea05117ffad4727b0971ed09122d5c91c4dc upstream.
Currently uses the worst case byte budgets on FS/LS bus bandwidth,
for example, for an isochronos IN endpoint with 192 bytes budget, it
will consume the whole 5 uframes(188 * 5) while the actual FS bus
budget should be just 192 bytes. It cause that many usb audio headsets
with 3 interfaces (audio input, audio output, and HID) cannot be
configured.
To improve it, changes to use "approximate" best case budget for FS/LS
bandwidth management. For the same endpoint from the above example,
the approximate best case budget is now reduced to (188 * 2) bytes.

This turned out not to be an error in usb-storage but rather a nested
device reset attempt. That is, as the rtl8712 driver was being
unbound from a composite device in preparation for an unrelated USB
reset (that driver does not have pre_reset or post_reset callbacks),
its ->remove routine called usb_reset_device() -- thus nesting one
reset call within another.
Performing a reset as part of disconnect processing is a questionable
practice at best. However, the bug report points out that the USB
core does not have any protection against nested resets. Adding a
reset_in_progress flag and testing it will prevent such errors in the
future.

commit d5dcc33677d7415c5f23b3c052f9e80cbab9ea4e upstream.
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.

commit 1b1b672cc1d4fb3065dac79efb8901bd6244ef69 upstream.
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.
