commit 1f3546ff3f0a1000971daef58406954bad3f7061 upstream.
Failing probe with -EPROBE_DEFER until all dependencies
listed in the _DEP (Operation Region Dependencies) object
have been met.
This will fix an issue where on some platforms UCSI ACPI
driver fails to probe because the address space handler for
the operation region that the UCSI ACPI interface uses has
not been loaded yet.

commit cfd54fa83a5068b61b7eb28d3c117d8354c74c7a upstream.
Userspace drivers that use a SetConfiguration() request to "lightweight"
reset an already configured usb device might cause data toggles to get out
of sync between the device and host, and the device becomes unusable.
The xHCI host requires endpoints to be dropped and added back to reset the
toggle. If USB core notices the new configuration is the same as the
current active configuration it will avoid these extra steps by calling
usb_reset_configuration() instead of usb_set_configuration().
A SetConfiguration() request will reset the device side data toggles.
Make sure usb_reset_configuration() function also drops and adds back the
endpoints to ensure data toggles are in sync.
To avoid code duplication split the current usb_disable_device() function
and reuse the endpoint specific part.

commit f4b9d8a582f738c24ebeabce5cc15f4b8159d74e upstream.
Clang static analysis reports this error
cdc-acm.c:409:3: warning: Use of memory after it is freed
acm_process_notification(acm, (unsigned char *)dr);
There are three problems, the first one is that dr is not reset
The variable dr is set with
if (acm->nb_index)
dr = (struct usb_cdc_notification *)acm->notification_buffer;
But if the notification_buffer is too small it is resized with
if (acm->nb_size) {
kfree(acm->notification_buffer);
acm->nb_size = 0;
}
alloc_size = roundup_pow_of_two(expected_size);
/*
* kmalloc ensures a valid notification_buffer after a
* use of kfree in case the previous allocation was too
* small. Final freeing is done on disconnect.
*/
acm->notification_buffer =
kmalloc(alloc_size, GFP_ATOMIC);
dr should point to the new acm->notification_buffer.
The second problem is any data in the notification_buffer is lost
when the pointer is freed. In the normal case, the current data
is accumulated in the notification_buffer here.
memcpy(&acm->notification_buffer[acm->nb_index],
urb->transfer_buffer, copy_size);
When a resize happens, anything before
notification_buffer[acm->nb_index] is garbage.
The third problem is the acm->nb_index is not reset on a
resizing buffer error.
So switch resizing to using krealloc and reassign dr and
reset nb_index.

Some values extracted by ncm_unwrap_ntb() could possibly lead to several
different out of bounds reads of memory. Specifically the values passed
to netdev_alloc_skb_ip_align() need to be checked so that memory is not

Resolve this by applying bounds checking to a number of different

commit 068834a2773b6a12805105cfadbb3d4229fc6e0a upstream.
The Sound Devices MixPre-D audio card suffers from the same defect
as the Sound Devices USBPre2: an endpoint shared between a normal
audio interface and a vendor-specific interface, in violation of the
USB spec. Since the USB core now treats duplicated endpoints as bugs
and ignores them, the audio endpoint isn't available and the card
can't be used for audio capture.
Along the same lines as commit bdd1b147b802 ("USB: quirks: blacklist
duplicate ep on Sound Devices USBPre2"), this patch adds a quirks
entry saying to ignore ep5in for interface 1, leaving it available for
use with standard audio interface 2.

commit f1ec7ae6c9f8c016db320e204cb519a1da1581b8 upstream.
Some device drivers call libusb_clear_halt when target ep queue
is not empty. (eg. spice client connected to qemu for usb redir)
Before commit f5249461b504 ("xhci: Clear the host side toggle
manually when endpoint is soft reset"), that works well.
But now, we got the error log:
EP not empty, refuse reset
xhci_endpoint_reset failed and left ep_state's EP_SOFT_CLEAR_TOGGLE
bit still set
So all the subsequent urb sumbits to the ep will fail with the
warn log:
Can't enqueue URB while manually clearing toggle
We need to clear ep_state EP_SOFT_CLEAR_TOGGLE bit after
xhci_endpoint_reset, even if it failed.

While fixing this also fix the double call to dwc2_lowlevel_hw_disable()
if dr_mode is set to USB_DR_MODE_PERIPHERAL. In such case low-level
hardware is already disabled before calling usb_add_gadget_udc(). That
function correctly preserves low-level hardware state, there is no need
for the second unconditional dwc2_lowlevel_hw_disable() call.

The function quirks_param_set() takes as argument a const char* pointer
to the new value of the usbcore.quirks parameter. It then casts this
pointer to a non-const char* pointer and passes it to the strsep()
function, which overwrites the value.
Fix this by creating a copy of the value using kstrdup() and letting
that copy be written to by strsep().

The set-led command is eight bytes long and starts with a command byte
followed by six bytes of RGB data and ends with a byte encoding a
frequency (see iuu_led() and iuu_rgbf_fill_buffer()).
The led activity helpers had a few long-standing bugs which corrupted
the command packets by inserting a second command byte and thereby
offsetting the RGB data and dropping the frequency in non-xmas mode.
In xmas mode, a related off-by-one error left the frequency field
uninitialised.

GISB bus error kernel panics have been observed during S2 transition
tests on the 7271t platform. The errors are a result of the BDC
interrupt handler trying to access BDC register space after the
system's suspend callbacks have completed.
Adding a suspend hook to the BDC driver that halts the controller before
S2 entry thus preventing unwanted access to the BDC register space during
this transition.

Multiple connects/disconnects can cause a crash on the second
disconnect. The driver had a problem where it would try to send
endpoint commands after it was disconnected which is not allowed
by the hardware. The fix is to only allow the endpoint commands
when the endpoint is connected. This will also fix issues that
showed up when using configfs to create gadgets.

commit ec37198acca7b4c17b96247697406e47aafe0605 upstream.
I've confirmed that the ASMedia ASM1142 has the same problem as the
ASM2142/ASM3142, in that it too reports that it supports 64-bit DMA
addresses when in fact it does not. As with the ASM2142/ASM3142, this
can cause problems on systems where the upper bits matter, and adding
the XHCI_NO_64BIT_SUPPORT quirk completely fixes the issue.
