The "*cmd" variable can be controlled by the user via debugfs. That means
"new_cam" can be as high as 255 while the size of the uc->updated[] array
is UCSI_MAX_ALTMODES (30).
The call tree is:
ucsi_cmd() // val comes from simple_attr_write_xsigned()
-> ucsi_send_command()
-> ucsi_send_command_common()
-> ucsi_run_command() // calls ucsi->ops->sync_control()

If the device was already runtime suspended then during system suspend
we cannot access the device registers else it will crash.
Also we cannot access any registers after dwc3_core_exit() on some
platforms so move the dwc3_enable_susphy() call to the top.

Commit 6ed05c68cbca ("usb: musb: sunxi: Explicitly release USB PHY on
exit") will cause that usb phy @glue->xceiv is accessed after released.
1) register platform driver @sunxi_musb_driver
// get the usb phy @glue->xceiv
sunxi_musb_probe() -> devm_usb_get_phy().
2) register and unregister platform driver @musb_driver
musb_probe() -> sunxi_musb_init()
use the phy here
//the phy is released here
musb_remove() -> sunxi_musb_exit() -> devm_usb_put_phy()
3) register @musb_driver again
musb_probe() -> sunxi_musb_init()
use the phy here but the phy has been released at 2).
...
Fixed by reverting the commit, namely, removing devm_usb_put_phy()
from sunxi_musb_exit().

self-powered devices
PD3.1 spec ("8.3.3.3.3 PE_SNK_Wait_for_Capabilities State") mandates
that the policy engine perform a hard reset when SinkWaitCapTimer
expires. Instead the code explicitly does a GET_SOURCE_CAP when the
timer expires as part of SNK_WAIT_CAPABILITIES_TIMEOUT. Due to this the
following compliance test failures are reported by the compliance tester
(added excerpts from the PD Test Spec):
* COMMON.PROC.PD.2#1:
The Tester receives a Get_Source_Cap Message from the UUT. This
message is valid except the following conditions: [COMMON.PROC.PD.2#1]
a. The check fails if the UUT sends this message before the Tester
has established an Explicit Contract
...
* TEST.PD.PROT.SNK.4:
...
4. The check fails if the UUT does not send a Hard Reset between
tTypeCSinkWaitCap min and max. [TEST.PD.PROT.SNK.4#1] The delay is
between the VBUS present vSafe5V min and the time of the first bit
of Preamble of the Hard Reset sent by the UUT.
For the purpose of interoperability, restrict the quirk introduced in
https://lore.kernel.org/all/20240523171806.223727-1-sebastian.reichel@collabora.com/
to only non self-powered devices as battery powered devices will not
have the issue mentioned in that commit.

For devm_usb_put_phy(), its comment says it needs to invoke usb_put_phy()
to release the phy, but it does not do that actually, so it can not fully
undo what the API devm_usb_get_phy() does, that is wrong, fixed by using
devres_release() instead of devres_destroy() within the API.

Fix a boot hang issue triggered when a USB3 device is incorrectly assumed
to be tunneled over USB4, thus attempting to create a device link between
the USB3 "consumer" device and the USB4 "supplier" Host Interface before
the USB4 side is properly bound to a driver.
This could happen if xhci isn't capable of detecting tunneled devices,
but ACPI tables contain all info needed to assume device is tunneled.
i.e. udev->tunnel_mode == USB_LINK_UNKNOWN.
It turns out that even for actual tunneled USB3 devices it can't be
assumed that the thunderbolt driver providing the tunnel is loaded
before the tunneled USB3 device is created.
The tunnel can be created by BIOS and remain in use by thunderbolt/USB4
host driver once it loads.
Solve this by making the device link "stateless", which doesn't create
a driver presence order dependency between the supplier and consumer
drivers.
It still guarantees correct suspend/resume and shutdown ordering.

During the aborting of a command, the software receives a command
completion event for the command ring stopped, with the TRB pointing
to the next TRB after the aborted command.
If the command we abort is located just before the Link TRB in the
command ring, then during the 'command ring stopped' completion event,
the xHC gives the Link TRB in the event's cmd DMA, which causes a
mismatch in handling command completion event.
To address this situation, move the 'command ring stopped' completion
event check slightly earlier, since the specific command it stopped
on isn't of significant concern.

Treat each completed full size write to /dev/ttyDBC0 as a separate usb
transfer. Make sure the size of the TRBs matches the size of the tty
write by first queuing as many max packet size TRBs as possible up to
the last TRB which will be cut short to match the size of the tty write.
This solves an issue where userspace writes several transfers back to
back via /dev/ttyDBC0 into a kfifo before dbgtty can find available
request to turn that kfifo data into TRBs on the transfer ring.
The boundary between transfer was lost as xhci-dbgtty then turned
everyting in the kfifo into as many 'max packet size' TRBs as possible.
DbC would then send more data to the host than intended for that
transfer, causing host to issue a babble error.
Refuse to write more data to kfifo until previous tty write data is
turned into properly sized TRBs with data size boundaries matching tty
write size

Some host controllers fail to produce the final completion event on an
isochronous TD which experienced an error mid TD. We deal with it by
flagging such TDs and checking if the next event points at the flagged
TD or at the next one, and giving back the flagged TD if the latter.
This is not enough, because the next TD may be missed by the xHC. Or
there may be no next TD but a ring underrun. We also need to get such
TD quickly out of the way, or errors on later TDs may be handled wrong.
If the next TD experiences a Missed Service Error, we will set the skip
flag on the endpoint and then attempt skipping TDs when yet another
event arrives. In such scenario, we ought to report the 'error mid TD'
transfer as such rather than skip it.
Another problem case are Stopped events. If we see one after an error
mid TD, we naively assume that it's a Force Stopped Event because it
doesn't match the pending TD, but in reality it might be an ordinary
Stopped event for the next TD, which we fail to recognize and handle.
Fix this by moving error mid TD handling before the whole TD skipping
loop. Remove unnecessary conditions, always give back the TD if the new
event points to any TRB outside it or if the pointer is NULL, as may be
the case in Ring Underrun and Overrun events on 1st gen hardware. Only
if the pending TD isn't flagged, consider other actions like skipping.
As a side effect of reordering with skip and FSE cases, error mid TD is
reordered with last_td_was_short check. This is harmless, because the
two cases are mutually exclusive - only one can happen in any given run
of handle_tx_event().
Tested on the NEC host and a USB camera with flaky cable. Dynamic debug
confirmed that Transaction Errors are sometimes seen, sometimes mid-TD,
sometimes followed by Missed Service. In such cases, they were finished
properly before skipping began.

Avoid xHC host from processing a cancelled URB by always turning
cancelled URB TDs into no-op TRBs before queuing a 'Set TR Deq' command.
If the command fails then xHC will start processing the cancelled TD
instead of skipping it once endpoint is restarted, causing issues like
Babble error.
This is not a complete solution as a failed 'Set TR Deq' command does not
guarantee xHC TRB caches are cleared.

The stream contex type (SCT) bitfield is used both in the stream context
data structure, and in the 'Set TR Dequeue pointer' command TRB.
In both cases it uses bits 3:1
The SCT_FOR_TRB(p) macro used to set the stream context type (SCT) field
for the 'Set TR Dequeue pointer' command TRB incorrectly shifts the value
1 bit left before masking the three bits.
Fix this by first masking and rshifting, just like the similar
SCT_FOR_CTX(p) macro does
This issue has not been visibile as the lost bit 3 is only used with
secondary stream arrays (SSA). Xhci driver currently only supports using
a primary stream array with Linear stream addressing.

The syzbot fuzzer has been encountering "task hung" problems ever
since the dummy-hcd driver was changed to use hrtimers instead of
regular timers. It turns out that the problems are caused by a subtle
difference between the timer_pending() and hrtimer_active() APIs.
The changeover blindly replaced the first by the second. However,
timer_pending() returns True when the timer is queued but not when its
callback is running, whereas hrtimer_active() returns True when the
hrtimer is queued _or_ its callback is running. This difference
occasionally caused dummy_urb_enqueue() to think that the callback
routine had not yet started when in fact it was almost finished. As a
result the hrtimer was not restarted, which made it impossible for the
driver to dequeue later the URB that was just enqueued. This caused
usb_kill_urb() to hang, and things got worse from there.
Since hrtimers have no API for telling when they are queued and the
callback isn't running, the driver must keep track of this for itself.
That's what this patch does, adding a new "timer_pending" flag and
setting or clearing it at the appropriate times.

The configfs store callback should return the number of bytes consumed
not the total number of bytes we actually stored. These could differ if
for example the passed in string had a newline we did not store.
If the returned value does not match the number of bytes written the
writer might assume a failure or keep trying to write the remaining bytes.
For example the following command will hang trying to write the final
newline over and over again (tested on bash 2.05b):
echo foo > function_name

Since commit 6d735722063a ("usb: dwc3: core: Prevent phy suspend during init"),
system suspend is broken on AM62 TI platforms.
Before that commit, both DWC3_GUSB3PIPECTL_SUSPHY and DWC3_GUSB2PHYCFG_SUSPHY
bits (hence forth called 2 SUSPHY bits) were being set during core
initialization and even during core re-initialization after a system
suspend/resume.
These bits are required to be set for system suspend/resume to work correctly
on AM62 platforms.
Since that commit, the 2 SUSPHY bits are not set for DEVICE/OTG mode if gadget
driver is not loaded and started.
For Host mode, the 2 SUSPHY bits are set before the first system suspend but
get cleared at system resume during core re-init and are never set again.
This patch resovles these two issues by ensuring the 2 SUSPHY bits are set
before system suspend and restored to the original state during system resume.

Using total USB2 phy number as port number to check all PORTSC values
would cause invalid memory access.

DWC3 programming guide mentions that when operating in USB2.0 speeds,
if GUSB2PHYCFG[6] or GUSB2PHYCFG[8] is set, it must be cleared prior
to issuing commands and may be set again after the command completes.
But currently while issuing EndXfer command without CmdIOC set, we
wait for 1ms after GUSB2PHYCFG is restored. This results in cases
where EndXfer command doesn't get completed and causes SMMU faults
since requests are unmapped afterwards. Hence restore GUSB2PHYCFG
after waiting for EndXfer command completion.

This reverts commit 86b20af11e84c26ae3fde4dcc4f490948e3f8035.
This patch leads to passing 0 to simple_read_from_buffer()
as a fifth argument, turning the read method into a nop.
The change is fundamentally flawed, as it breaks the driver.

support
Introduce new kernel config symbol for Microchip usb5744 SMBus programming
support. Since usb5744 i2c initialization routine uses i2c SMBus APIs these
APIs should only be invoked when kernel has I2C support. This new kernel
config describes the dependency on I2C kernel support and fix the below
build issues when USB_ONBOARD_DEV=y and CONFIG_I2C=m.
riscv64-linux-ld: drivers/usb/misc/onboard_usb_dev.o:
undefined reference to `i2c_find_device_by_fwnode'
drivers/usb/misc/onboard_usb_dev.c:408:(.text+0xb24): undefined
reference to `i2c_smbus_write_block_data'
<snip>
Parsing of the i2c-bus bus handle is not put under usb5744 kernel config
check as the intention is to report an error when DT is configured for
usb5744 SMBus support and kernel has USB_ONBOARD_DEV_USB5744 disabled.

When dwc3_resume_common() returns an error, runtime pm is left in
suspended and disabled state in dwc3_resume(). Since the device
is suspended, its parent devices (like the power domain or glue
driver) could also be suspended and may have released resources
that dwc requires. Consequently, calling dwc3_suspend_common() in
this situation could result in attempts to access unclocked or
unpowered registers.
To prevent these problems, runtime PM should always be re-enabled,
even after failed resume attempts. This ensures that
dwc3_suspend_common() is skipped in such cases.

no_llseek had been defined to NULL two years ago, in commit 868941b14441
("fs: remove no_llseek")
To quote that commit,
At -rc1 we'll need do a mechanical removal of no_llseek -
git grep -l -w no_llseek | grep -v porting.rst | while read i; do
sed -i '/\<no_llseek\>/d' $i
done
would do it.
Unfortunately, that hadn't been done. Linus, could you do that now, so
that we could finally put that thing to rest? All instances are of the
form
.llseek = no_llseek,
so it's obviously safe.
