Pull USB fixes from Greg KH:
"Let's try this again... Here are some USB fixes for 5.9-rc3.
This differs from the previous pull request for this release in that
the usb gadget patch now does not break some systems, and actually
does what it was intended to do. Many thanks to Marek Szyprowski for
quickly noticing and testing the patch from Andy Shevchenko to resolve
this issue.
Additionally, some more new USB quirks have been added to get some new
devices to work properly based on user reports.
Other than that, the patches are all here, and they contain:
- usb gadget driver fixes
- xhci driver fixes
- typec fixes
- new quirks and ids
- fixes for USB patches that went into 5.9-rc1.
All of these have been tested in linux-next with no reported issues"

The PSZ-HA* family of USB disk drives from Sony can't handle the
REPORT OPCODES command when using the UAS protocol. This patch adds
an appropriate quirks entry.

This device does not support UAS properly and a similar entry already
exists in drivers/usb/storage/unusual_uas.h. Without this patch,
storage_probe() defers the handling of this device to UAS, which cannot
handle it either.

If the function platform_get_irq() failed, the negative value
returned will not be detected here. So fix error handling in
exynos_ohci_probe(). And when get irq failed, the function
platform_get_irq() logs an error message, so remove redundant
message here.

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.

2.3.1.2 failures
The patch addresses the compliance test failures while running TDA
2.3.1.1 and TDA 2.3.1.2 of the "PD Communications Engine USB PD
Compliance MOI" test plan published in https://www.usb.org/usbc.
For a product to be Type-C compliant, it's expected that these tests
are run on usb.org certified Type-C compliance tester as mentioned in
https://www.usb.org/usbc.
While the purpose of TDA 2.3.1.1 and TDA 2.3.1.2 is to verify that
the static and dynamic electrical capabilities of a Source meet the
requirements for each PDO offered, while doing so, the tests also
monitor that the timing of the VBUS waveform versus the messages meets
the requirements for Hard Reset defined in PROT-PROC-HR-TSTR as
mentioned in step 11 of TDA.2.3.1.1 and step 15 of TDA.2.3.1.2.
TDB.2.2.13.1: PROT-PROC-HR-TSTR Procedure and Checks for Tester
Originated Hard Reset
Purpose: To perform the appropriate protocol checks relating to any
circumstance in which the Hard Reset signal is sent by the Tester.
UUT is behaving as source:
The Tester sends a Hard Reset signal.
1. Check VBUS stays within present valid voltage range for
tPSHardReset min (25ms) after last bit of Hard Reset signal.
[PROT_PROC_HR_TSTR_1]
2. Check that VBUS starts to fall below present valid voltage range by
tPSHardReset max (35ms). [PROT_PROC_HR_TSTR_2]
3. Check that VBUS reaches vSafe0V within tSafe0v max (650 ms).
[PROT_PROC_HR_TSTR_3]
4. Check that VBUS starts rising to vSafe5V after a delay of
tSrcRecover (0.66s - 1s) from reaching vSafe0V. [PROT_PROC_HR_TSTR_4]
5. Check that VBUS reaches vSafe5V within tSrcTurnOn max (275ms) of
rising above vSafe0v max (0.8V). [PROT_PROC_HR_TSTR_5] Power Delivery
Compliance Plan 139 6. Check that Source Capabilities are finished
sending within tFirstSourceCap max (250ms) of VBUS reaching vSafe5v
min. [PROT_PROC_HR_TSTR_6].
This is in line with 7.1.5 Response to Hard Resets of the USB Power
Delivery Specification Revision 3.0, Version 1.2,
"Hard Reset Signaling indicates a communication failure has occurred
and the Source Shall stop driving VCONN, Shall remove Rp from the
VCONN pin and Shall drive VBUS to vSafe0V as shown in Figure 7-9. The
USB connection May reset during a Hard Reset since the VBUS voltage
will be less than vSafe5V for an extended period of time. After
establishing the vSafe0V voltage condition on VBUS, the Source Shall
wait tSrcRecover before re-applying VCONN and restoring VBUS to
vSafe5V. A Source Shall conform to the VCONN timing as specified in
[USB Type-C 1.3]."
With the above guidelines from the spec in mind, TCPM does not turn
off VCONN while entering SRC_HARD_RESET_VBUS_OFF. The patch makes TCPM
turn off VCONN while entering SRC_HARD_RESET_VBUS_OFF and turn it back
on while entering SRC_HARD_RESET_VBUS_ON along with vbus instead of
having VCONN on through hardreset.
Also, the spec clearly states that "After establishing the vSafe0V
voltage condition on VBUS", the Source Shall wait tSrcRecover before
re-applying VCONN and restoring VBUS to vSafe5V.
TCPM does not conform to this requirement. If the TCPC driver calls
tcpm_vbus_change with vbus off signal, TCPM right away enters
SRC_HARD_RESET_VBUS_ON without waiting for tSrcRecover.
For TCPC's which are buggy/does not call tcpm_vbus_change, TCPM
assumes that the vsafe0v is instantaneous as TCPM only waits
tSrcRecover instead of waiting for tSafe0v + tSrcRecover.
This patch also fixes this behavior by making sure that TCPM waits for
tSrcRecover before transitioning into SRC_HARD_RESET_VBUS_ON when
tcpm_vbus_change is called by TCPC.
When TCPC does not call tcpm_vbus_change, TCPM assumes the worst case
i.e. tSafe0v + tSrcRecover before transitioning into
SRC_HARD_RESET_VBUS_ON.

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
overflowed.
Resolve this by applying bounds checking to a number of different
indexes and lengths of the structure parsing logic.

size can potentially hold an overflowed value if its assigned expression
is left unchecked, leading to a smaller than needed allocation when
vla_group_size() is used by callers to allocate memory.
To fix this, add a test for saturation before declaring variables and an
overflow check to (n) * sizeof(type).
If the expression results in overflow, vla_group_size() will return SIZE_MAX.

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.

Sometimes re-plugging a USB device during system sleep renders the device

Because PLS equals to XDEV_RESUME, xHCI driver reports U3 to usbcore,
despite of CAS bit is flagged.
So proritize CAS over XDEV_RESUME to let usbcore handle warm-reset for
the port.

When a new device with a specialised device driver is plugged in, the
new driver will be modprobe()'d but the driver core will attach the
"generic" driver to the device.
After that, nothing will trigger a reprobe when the modprobe()'d device
driver has finished initialising, as the device has the "generic"
driver attached to it.
Trigger a reprobe ourselves when new specialised drivers get registered.

The ppm_lock really only needs to be hold during 2 functions:
ucsi_reset_ppm() and ucsi_run_command().
Push the taking of the lock down into these 2 functions, renaming
ucsi_run_command() to ucsi_send_command() which was an existing
wrapper already taking the lock for its callers.
This simplifies things for the callers and removes the difference
between ucsi_send_command() and ucsi_run_command() which has led
to various locking bugs in the past.

Fix 2 unlocked ucsi_run_command calls:
1. ucsi_handle_connector_change() contains one ucsi_send_command() call,
which takes the ppm_lock for it; and one ucsi_run_command() call which
relies on the caller have taking the ppm_lock.
ucsi_handle_connector_change() does not take the lock, so the
second (ucsi_run_command) calls should also be ucsi_send_command().
2. ucsi_get_pdos() gets called from ucsi_handle_connector_change() which
does not hold the ppm_lock, so it also must use ucsi_send_command().
This commit also adds a WARN_ON(!mutex_is_locked(&ucsi->ppm_lock)); to
ucsi_run_command() to avoid similar problems getting re-introduced in
the future.

Lockdep reports an AB BA lock inversion between ucsi_init() and
ucsi_handle_connector_change():
AB order:
1. ucsi_init takes ucsi->ppm_lock (it runs with that locked for the
duration of the function)
2. usci_init eventually end up calling ucsi_register_displayport,
which takes ucsi_connector->lock
BA order:
1. ucsi_handle_connector_change work is started, takes ucsi_connector->lock
2. ucsi_handle_connector_change calls ucsi_send_command which takes
ucsi->ppm_lock
The ppm_lock really only needs to be hold during 2 functions:
ucsi_reset_ppm() and ucsi_run_command().
This commit fixes the AB BA lock inversion by making ucsi_init drop the
ucsi->ppm_lock before it starts registering ports; and replacing any
ucsi_run_command() calls after this point with ucsi_send_command()
(which is a wrapper around run_command taking the lock while handling
the command).
Some of the replacing of ucsi_run_command with ucsi_send_command
in the helpers used during port registration also fixes a number of
code paths after registration which call ucsi_run_command() without
holding the ppm_lock:
1. ucsi_altmode_update_active() call in ucsi/displayport.c
2. ucsi_register_altmodes() call from ucsi_handle_connector_change()
(through ucsi_partner_change())

Commit 88b7381a939d ("USB: Select better matching USB drivers when
available") introduced the use of a "match" function to select a
non-generic/better driver for a particular USB device. This
unfortunately breaks the operation of usbip in general, as reported in
the kernel bugzilla with bug 208267 (linked below).
Upon inspecting the aforementioned commit, one can observe that the
original code in the usb_device_match function used to return 1
unconditionally, but the aforementioned commit makes the usb_device_match
function use identifier tables and "match" virtual functions, if either of
them are available.
Hence, this commit implements a match function for usbip that
unconditionally returns true to ensure that usbip is functional again.
This change has been verified to restore usbip functionality, with a
v5.7.y kernel on an up-to-date version of Qubes OS 4.0, which uses
usbip to redirect USB devices between VMs.
Thanks to Jonathan Dieter for the effort in bisecting this issue down
to the aforementioned commit.

lvs_rh_probe() can return some nonnegative value from usb_control_msg()
when it is less than "USB_DT_HUB_NONVAR_SIZE + 2" that is considered as
a failure. Make lvs_rh_probe() return -EINVAL in this case.

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.

The usb_request->zero doesn't apply for isoc. Also, if we prepare a
0-length (ZLP) TRB for the OUT direction, we need to prepare an extra
TRB to pad up to the MPS alignment. Use the same bounce buffer for the
ZLP TRB and the extra pad TRB.

The SG list may be set up with entry size more than the requested
length. Check the usb_request->length and make sure that we don't setup
the TRBs to send/receive more than requested. This case may occur when
the SG entry is allocated up to a certain minimum size, but the request
length is less than that. It can also occur when the request is reused
for a different request length.

Register a power supply charger, whose online state depends on whether
the USB role is set to device or not.
This is useful when the USB role is the only way to know if the device
is charging from USB. The API is the standard power supply charger API,
you get a /sys/class/power_supply/xxx/online node which tells you the
state of the charger.
The sole purpose of this is to give userspace applications a way to
know whether or not the charger is plugged.
