usb: dwc3: gadget: Fix event pending check
commit 7441b273388b9a59d8387a03ffbbca9d5af6348c upstream.
The DWC3_EVENT_PENDING flag is used to protect against invalid call to
top-half interrupt handler, which can occur when there's a delay in
software detection of the interrupt line deassertion.
However, the clearing of this flag was done prior to unmasking the
interrupt line, creating opportunity where the top-half handler can
come. This breaks the serialization and creates a race between the
top-half and bottom-half handler, resulting in losing synchronization
between the controller and the driver when processing events.
To fix this, make sure the clearing of the DWC3_EVENT_PENDING is done at
the end of the bottom-half handler.
Fixes:

UPSTREAM: usb: dwc3: gadget: Change to dev_dbg() when queuing to inactive gadget/ep
Since function drivers will still be active until dwc3_disconnect_gadget() is called, some applications will continue to queue packets to DWC3 gadget. This can lead to a flood of messages regarding failed ep queue, as the endpoint is in the process of being disabled. Change the log level to debug, so that it can be enabled when debugging issues.

usb: dwc3: gadget: Replace list_for_each_entry_safe() if using giveback
[ Upstream commit bf594d1d0c1d7b895954018043536ffd327844f9 ]
The list_for_each_entry_safe() macro saves the current item (n) and
the item after (n+1), so that n can be safely removed without
corrupting the list. However, when traversing the list and removing
items using gadget giveback, the DWC3 lock is briefly released,
allowing other routines to execute. There is a situation where, while
items are being removed from the cancelled_list using
dwc3_gadget_ep_cleanup_cancelled_requests(), the pullup disable
routine is running in parallel (due to UDC unbind). As the cleanup
routine removes n, and the pullup disable removes n+1, once the
cleanup retakes the DWC3 lock, it references a request who was already
removed/handled. With list debug enabled, this leads to a panic.
Ensure all instances of the macro are replaced where gadget giveback
is used.
Example call stack:

usb: dwc3: gadget: Move null pinter check to proper place
commit 3c5880745b4439ac64eccdb040e37fc1cc4c5406 upstream.
When dwc3_gadget_ep_cleanup_completed_requests() called to
dwc3_gadget_giveback() where the dwc3 lock is released, other thread is

clear endpoint descriptor pointer which leds to the null pointer
dereference problem. So needs to move the null pointer check to a proper
place.

FROMLIST: usb: dwc3: Fix ep0 handling when getting reset while doing control transfer
According to the databook ep0 should be in setup phase during reset. If host issues reset between control transfers, ep0 will be in an invalid state. Fix this by issuing stall and restart on ep0 if it is not in setup phase. Also SW needs to complete pending control transfer and setup core for next setup stage as per data book. Hence check ep0 state during reset interrupt handling and make sure active transfers on ep0 out/in endpoint are stopped by queuing ENDXFER command for that endpoint and restart ep0 out again to receive next setup packet.

usb: dwc3: gadget: Return proper request status
commit c7428dbddcf4ea1919e1c8e15f715b94ca359268 upstream.
If the user sets the usb_request's no_interrupt, then there will be no
completion event for the request. Currently the driver incorrectly uses
the event status of a different request to report the status for a
request with no_interrupt. The dwc3 driver needs to check the TRB status
associated with the request when reporting its status.
Note: this is only applicable to missed_isoc TRB completion status, but
the other status are also listed for completeness/documentation.

UPSTREAM: usb: dwc3: gadget: Wait for ep0 xfers to complete during dequeue
If a Setup packet is received but yet to DMA out, the controller will not process the End Transfer command of any endpoint. Polling of its DEPCMD.CmdAct may block setting up TRB for Setup packet, causing a command timeout. This may occur if the driver doesn’t service the completion interrupt of the control status stage yet due to system latency, then it won’t prepare TRB and start the transfer for the next Setup Stage. To the host side, the control transfer had completed, and the host can send a new Setup packet at this point. In the meanwhile, if the driver receives an async call to dequeue a request (triggering End Transfer) to any endpoint, then the driver will service that End transfer first, blocking the control status stage completion handler. Since no TRB is available for the Setup stage, the Setup packet can’t be DMA’ed out and the End Transfer gets hung. The driver must not block setting up of the Setup stage. So track and only issue the End Transfer command only when there’s Setup TRB prepared so that the controller can DMA out the Setup packet. Delay the End transfer command if there's no Setup TRB available. This is applicable to all DWC_usb3x IPs.

UPSTREAM: usb: dwc3: gadget: Avoid starting DWC3 gadget during UDC unbind
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.

usb: dwc3: gadget: Let the interrupt handler disable bottom halves.
commit 84918a89d6efaff075de570b55642b6f4ceeac6d upstream.
The interrupt service routine registered for the gadget is a primary
handler which mask the interrupt source and a threaded handler which
handles the source of the interrupt. Since the threaded handler is
voluntary threaded, the IRQ-core does not disable bottom halves before
invoke the handler like it does for the forced-threaded handler.
Due to changes in networking it became visible that a network gadget's
completions handler may schedule a softirq which remains unprocessed.
The gadget's completion handler is usually invoked either in hard-IRQ or
soft-IRQ context. In this context it is enough to just raise the softirq
because the softirq itself will be handled once that context is left.
In the case of the voluntary threaded handler, there is nothing that
will process pending softirqs. Which means it remain queued until
another random interrupt (on this CPU) fires and handles it on its exit
path or another thread locks and unlocks a lock with the bh suffix.
Worst case is that the CPU goes idle and the NOHZ complains about
unhandled softirqs.
Disable bottom halves before acquiring the lock (and disabling
interrupts) and enable them after dropping the lock. This ensures that
any pending softirqs will handled right away.

usb: dwc3: gadget: Prevent core from processing stale TRBs
commit 117b4e96c7f362eb6459543883fc07f77662472c upstream.
With CPU re-ordering on write instructions, there might
be a chance that the HWO is set before the TRB is updated
with the new mapped buffer address.
And in the case where core is processing a list of TRBs
it is possible that it fetched the TRBs when the HWO is set
but before the buffer address is updated.
Prevent this by adding a memory barrier before the HWO
is updated to ensure that the core always process the
updated TRBs.

descriptor. But it could be cleared in __dwc3_gadget_ep_disable()
when accessory disconnected. So we need to check whether it is null
or not before dereferencing it.

usb: dwc3: gadget: Check for L1/L2/U3 for Start Transfer
commit 63c4c320ccf77074ffe9019ac596603133c1b517 upstream.
The programming guide noted that the driver needs to verify if the link
state is in U0 before executing the Start Transfer command. If it's not
in U0, the driver needs to perform remote wakeup. This is not accurate.
If the link state is in U1/U2, then the controller will not respond to
link recovery request from DCTL.ULSTCHNGREQ. The Start Transfer command
will trigger a link recovery if it is in U1/U2. A clarification will be
added to the programming guide for all controller versions.
The current implementation shouldn't cause any functional issue. It may
occasionally report an invalid time out warning from failed link
recovery request. The driver will still go ahead with the Start Transfer
command if the remote wakeup fails. The new change only initiates remote
wakeup where it is needed, which is when the link state is in L1/L2/U3.

usb: dwc3: gadget: Ignore NoStream after End Transfer
commit d74dc3e9f58c28689cef1faccf918e06587367d3 upstream.
The End Transfer command from a stream endpoint will generate a NoStream
event, and we should ignore it. Currently we set the flag
DWC3_EP_IGNORE_NEXT_NOSTREAM to track this prior to sending the command,
and it will be cleared on the next stream event. However, a stream event
may be generated before the End Transfer command completion and
prematurely clear the flag. Fix this by setting the flag on End Transfer
completion instead.

usb: dwc3: gadget: Skip resizing EP's TX FIFO if already resized
[ Upstream commit 876a75cb520f5869533a30a6ca01545ec817b7a0 ]
Some functions may dynamically enable and disable their endpoints
regularly throughout their operation, particularly when Set Interface
is employed to switch between Alternate Settings. For instance the
UAC2 function has its respective endpoints for playback & capture
associated with AltSetting 1, in which case those endpoints would not
get enabled until the host activates the AltSetting. And they
conversely become disabled when the interfaces' AltSetting 0 is
chosen.
With the DWC3 FIFO resizing algorithm recently added, every
usb_ep_enable() call results in a call to resize that EP's TXFIFO,
but if the same endpoint is enabled again and again, this incorrectly
leads to FIFO RAM allocation exhaustion as the mechanism did not
account for the possibility that endpoints can be re-enabled many
times.
Example log splat:
dwc3 a600000.dwc3: Fifosize(3717) > RAM size(3462) ep3in depth:217973127
configfs-gadget gadget: u_audio_start_capture:521 Error!
dwc3 a600000.dwc3: request 000000000be13e18 was not queued to ep3in
Add another bit DWC3_EP_TXFIFO_RESIZED to dep->flags to keep track of
whether an EP had already been resized in the current configuration.
If so, bail out of dwc3_gadget_resize_tx_fifos() to avoid the
calculation error resulting from accumulating the EP's FIFO depth
repeatedly. This flag is retained across multiple ep_disable() and
ep_enable() calls and is cleared when GTXFIFOSIZn is reset in
dwc3_gadget_clear_tx_fifos() upon receiving the next Set Config.

usb: dwc3: gadget: Stop EP0 transfers during pullup disable
During a USB cable disconnect, or soft disconnect scenario, a pending
SETUP transaction may not be completed, leading to the following
error:
dwc3 a600000.dwc3: timed out waiting for SETUP phase
If this occurs, then the entire pullup disable routine is skipped and
proper cleanup and halting of the controller does not complete.
Instead of returning an error (which is ignored from the UDC
perspective), allow the pullup disable routine to continue, which
will also handle disabling of EP0/1. This will end any active
transfers as well. Ensure to clear any delayed_status also, as the
timeout could happen within the STATUS stage.

usb: dwc3: gadget: Fix dwc3_calc_trbs_left()
We can't depend on the TRB's HWO bit to determine if the TRB ring is
"full". A TRB is only available when the driver had processed it, not
when the controller consumed and relinquished the TRB's ownership to the
driver. Otherwise, the driver may overwrite unprocessed TRBs. This can
happen when many transfer events accumulate and the system is slow to
process them and/or when there are too many small requests.
If a request is in the started_list, that means there is one or more
unprocessed TRBs remained. Check this instead of the TRB's HWO bit
whether the TRB ring is full.

usb: dwc3: gadget: Avoid runtime resume if disabling pullup
If the device is already in the runtime suspended state, any call to
the pullup routine will issue a runtime resume on the DWC3 core
device. If the USB gadget is disabling the pullup, then avoid having
to issue a runtime resume, as DWC3 gadget has already been
halted/stopped.
This fixes an issue where the following condition occurs:
usb_gadget_remove_driver()
-->usb_gadget_disconnect()
-->dwc3_gadget_pullup(0)
-->pm_runtime_get_sync() -> ret = 0
-->pm_runtime_put() [async]
-->usb_gadget_udc_stop()
-->dwc3_gadget_stop()
-->dwc->gadget_driver = NULL
...
dwc3_suspend_common()
-->dwc3_gadget_suspend()
-->DWC3 halt/stop routine skipped, driver_data == NULL
This leads to a situation where the DWC3 gadget is not properly
stopped, as the runtime resume would have re-enabled EP0 and event
interrupts, and since we avoided the DWC3 gadget suspend, these
resources were never disabled.

usb: dwc3: gadget: Use list_replace_init() before traversing lists
The list_for_each_entry_safe() macro saves the current item (n) and
the item after (n+1), so that n can be safely removed without
corrupting the list. However, when traversing the list and removing
items using gadget giveback, the DWC3 lock is briefly released,
allowing other routines to execute. There is a situation where, while
items are being removed from the cancelled_list using
dwc3_gadget_ep_cleanup_cancelled_requests(), the pullup disable
routine is running in parallel (due to UDC unbind). As the cleanup
routine removes n, and the pullup disable removes n+1, once the
cleanup retakes the DWC3 lock, it references a request who was already
removed/handled. With list debug enabled, this leads to a panic.
Ensure all instances of the macro are replaced where gadget giveback
is used.
Example call stack:
Thread#1:
__dwc3_gadget_ep_set_halt() - CLEAR HALT
-> dwc3_gadget_ep_cleanup_cancelled_requests()
->list_for_each_entry_safe()
->dwc3_gadget_giveback(n)
->dwc3_gadget_del_and_unmap_request()- n deleted[cancelled_list]
->spin_unlock
->Thread#2 executes
...
->dwc3_gadget_giveback(n+1)
->Already removed!
Thread#2:
dwc3_gadget_pullup()
->waiting for dwc3 spin_lock
...
->Thread#1 released lock
->dwc3_stop_active_transfers()
->dwc3_remove_requests()
->fetches n+1 item from cancelled_list (n removed by Thread#1)
->dwc3_gadget_giveback()
->dwc3_gadget_del_and_unmap_request()- n+1
deleted[cancelled_list]
->spin_unlock
Fix this condition by utilizing list_replace_init(), and traversing
through a local copy of the current elements in the endpoint lists.
This will also set the parent list as empty, so if another thread is
also looping through the list, it will be empty on the next iteration.

usb: dwc3: Resize TX FIFOs to meet EP bursting requirements
Some devices have USB compositions which may require multiple endpoints that support EP bursting. HW defined TX FIFO sizes may not always be sufficient for these compositions. By utilizing flexible TX FIFO allocation, this allows for endpoints to request the required FIFO depth to achieve higher bandwidth. With some higher bMaxBurst configurations, using a larger TX FIFO size results in better TX throughput. By introducing the check_config() callback, the resizing logic can fetch the maximum number of endpoints used in the USB composition (can contain multiple configurations), which helps ensure that the resizing logic can fulfill the configuration(s), or return an error to the gadget layer otherwise during bind time.

usb: dwc3: debugfs: Add and remove endpoint dirs dynamically
The DWC3 DebugFS directory and files are currently created once
during probe. This includes creation of subdirectories for each
of the gadget's endpoints. This works fine for peripheral-only
controllers, as dwc3_core_init_mode() calls dwc3_gadget_init()
just prior to calling dwc3_debugfs_init().
However, for dual-role controllers, dwc3_core_init_mode() will
instead call dwc3_drd_init() which is problematic in a few ways.
First, the initial state must be determined, then dwc3_set_mode()
will have to schedule drd_work and by then dwc3_debugfs_init()
could have already been invoked. Even if the initial mode is
peripheral, dwc3_gadget_init() happens after the DebugFS files
are created, and worse so if the initial state is host and the
controller switches to peripheral much later. And secondly,
even if the gadget endpoints' debug entries were successfully
created, if the controller exits peripheral mode, its dwc3_eps
are freed so the debug files would now hold stale references.
So it is best if the DebugFS endpoint entries are created and
removed dynamically at the same time the underlying dwc3_eps are.
Do this by calling dwc3_debugfs_create_endpoint_dir() as each
endpoint is created, and conversely remove the DebugFS entry when
the endpoint is freed.

usb: dwc3: gadget: Bail from dwc3_gadget_exit() if dwc->gadget is NULL
There exists a possible scenario in which dwc3_gadget_init() can fail:
during during host -> peripheral mode switch in dwc3_set_mode(), and
a pending gadget driver fails to bind. Then, if the DRD undergoes
another mode switch from peripheral->host the resulting
dwc3_gadget_exit() will attempt to reference an invalid and dangling
dwc->gadget pointer as well as call dma_free_coherent() on unmapped
DMA pointers.
The exact scenario can be reproduced as follows:
- Start DWC3 in peripheral mode
- Configure ConfigFS gadget with FunctionFS instance (or use g_ffs)
- Run FunctionFS userspace application (open EPs, write descriptors, etc)
- Bind gadget driver to DWC3's UDC
- Switch DWC3 to host mode
=> dwc3_gadget_exit() is called. usb_del_gadget() will put the
ConfigFS driver instance on the gadget_driver_pending_list
- Stop FunctionFS application (closes the ep files)
- Switch DWC3 to peripheral mode
=> dwc3_gadget_init() fails as usb_add_gadget() calls
check_pending_gadget_drivers() and attempts to rebind the UDC
to the ConfigFS gadget but fails with -19 (-ENODEV) because the
FFS instance is not in FFS_ACTIVE state (userspace has not
re-opened and written the descriptors yet, i.e. desc_ready!=0).
- Switch DWC3 back to host mode
=> dwc3_gadget_exit() is called again, but this time dwc->gadget
is invalid.
Although it can be argued that userspace should take responsibility
for ensuring that the FunctionFS application be ready prior to
allowing the composite driver bind to the UDC, failure to do so
should not result in a panic from the kernel driver.
Fix this by setting dwc->gadget to NULL in the failure path of
dwc3_gadget_init() and add a check to dwc3_gadget_exit() to bail out
unless the gadget pointer is valid.

usb: dwc3: gadget: Disable gadget IRQ during pullup disable
Current sequence utilizes dwc3_gadget_disable_irq() alongside
synchronize_irq() to ensure that no further DWC3 events are generated.
However, the dwc3_gadget_disable_irq() API only disables device
specific events. Endpoint events can still be generated. Briefly
disable the interrupt line, so that the cleanup code can run to
prevent device and endpoint events. (i.e. __dwc3_gadget_stop() and
dwc3_stop_active_transfers() respectively)
Without doing so, it can lead to both the interrupt handler and the

will cause an incorrect count being read from future interrupts.

usb: dwc3: gadget: Rename EOPF event macros to Suspend
The device event corresponding to End of Periodic Frame is only found on older IP revisions (2.10a and prior, according to a cursory SNPS databook search). On revisions 2.30a and newer, including DWC3.1, the same event value and corresponding DEVTEN bit were repurposed to indicate that the link has gone into suspend state (U3 or L2/L1). EOPF events had never been enabled before in this driver, and going forward we expect current and future DWC3-based devices won't likely to be using such old DWC3 IP revisions either. Hence rather than keeping the deprecated EOPF macro names let's rename them to indicate their usage for suspend events.

Note that often the host already brings the device out of low power
before it sends/requests the next transfer. So, the user won't see any
issue when the device starts transfer then. This issue is more
noticeable in cases when the device delays starting transfer, which can
