It always sets DWC3_EP_END_TRANSFER_PENDING in dwc3_stop_active_transfer
even if dwc3_send_gadget_ep_cmd fails. It can cause some problems like
skipping clear stall commmand or giveback from dequeue. We fix to set it
only when ep cmd success. Additionally, We clear DWC3_EP_TRANSFER_STARTED
for next trb to start transfer not update transfer.

So is this two different changes?

How does it fail? Timed out?

We shouldn't do this. Things will be out of sync. It may work for 1
scenario, but it won't work for others.

Please help me understand a few things:

1) What is the scenario that triggers this? Is it random?

2) Are there other traffics pending while issuing the End Transfer
command? If so, what transfer type(s)?

3) Have you tried increasing the timeout?

BR,
Thinh

ep cmd timeout occurs on dequeue request from user side. End Transfer command
would be sent in dwc3_stop_active transfer.

This issue occurs very rarely on customer. I only have restricted
information. That's why I've been trying to reproduce it.

Wesley may have run into same issue and you can see this issue in detail.

Hi greg,

Below is commit id to fix.

commit c58d8bfc77a2c7f6ff6339b58c9fca7ae6f57e70
Author: Thinh Nguyen <Thinh.Nguyen@synopsys.com>

    usb: dwc3: gadget: Check END_TRANSFER completion

    While the END_TRANSFER command is sent but not completed, any request
    dequeue during this time will cause the driver to issue the END_TRANSFER
    command. The driver needs to submit the command only once to stop the
    controller from processing further. The controller may take more time to
    process the same command multiple times unnecessarily. Let's add a flag
    DWC3_EP_END_TRANSFER_PENDING to check for this condition.

At the high level, what's triggering the request dequeue? Is it from a
disconnect, change of interface, or simply function driver protocol that
changes it.

What application was used to trigger this?

Sorry for jumping in here, but looks like Daehwan is running into a
similar issue I am seeing as well.

At least in my scenario, the dequeue is coming from a function driver
which exposes a device to userspace.  Once that device is closed, it
will issue a dequeue on all pending/submitted requests.

For the cases where we've collected a crash log, we can see that during
the END transfer timeouts there was always a pending EP0 transaction.
We had reached out to our internal HW folks to get some inputs on what
could be causing this kind of issue, and we were able to get some
recommendations from their Synopsis POCs.

It was mentioned that if there was an active EP0 transfer, an end
transfer command on a non-control EP can fail w/ timed out.

Let me see if I have any previous traces I can share.  If not, I have a
pretty reliable repro set up I can collect a trace for you.  For now, I
will focus on just getting the endxfer timeout seen during ep dequeue.
As mentioned on my patchset, this can happen during device-initiated
disconnect as well.

Dequeuing request is coming from the function driver, but what causes
the dequeue. For example, the End Transfer command due to a disconnect
may give a different clues than a dequeue from a change of interface.

It's "Synopsys" :)

What controller version are you using? And what version is Jung using?
Do you have the STAR number of the issue. If you're using a different
version than Jung's, then it may not be the same issue.

Your patch set is still on my todo list. I haven't reviewed it. There's
some concern looking at it from a first glance, I'll check it out more
thoroughly later.

Can you provide the tracepoints?

I sent patches to my client and he said this issue would not occur after
applying them. In fact, They are not totally equal with those we are

The point is there would be some requests pending without giveback-ed.
They're from removing function driver(ffs_aio_cancel). It could cause
the function driver would wait for dequeue requests completed.

For us, once the application exits, the corresponding userspace
device/port is closed.  This triggers the function driver to clean up
any pending/queued USB requests.  It doesn't have any association w/ any
USB cable disconnect, or interface change in this case, it is controlled
solely on the application exiting/stopped.

Removing function driver? Did it go through function unbind?

If this is the case, then it's different than the scenario Wesley's

I may misunderstand the description, or something doesn't match up. If
"removing function driver" means function unbind, then this will trigger
disabling the endpoints and dwc3_remove_requests(). If
dwc3_remove_requests() was called, then the dwc3 driver would give back
the requests regardless whether the End Transfer command was completed.

If this is not the full log, can you send the full driver log. That
would give more clues.

Can you provide a full trace?

Btw, when you experiment with increasing the timeout to 10 seconds, did
you use the mdelay() in each loop? The delta time for End Transfer
timeout here seems very small.

Note: The End Transfer command should _only_ gets stuck if the DMA for a
the Setup packet isn’t completed, which should be a short time. It
doesn't look like the case here. (Hopefully the full driver tracepoint
give more clues).

Thanks,

Sorry for doing this, but we didn't have a way to share the file
directly, so I have to paste the trace below. :/

This particular run did not modify the timeout for the cmd status polling.

Is that something that you want to try?  Not pertaining to this dequeue
situation, during the pullup disable path debug, I noticed that as long
as there was a pending EP0 SETUP packet (not data/status) cached in the
controller, it would also have endxfer timeouts on non-control EPs.  We
were able to capture a bus sniffer log + ftrace, and it showed that at
the point of the error, the lecroy/bus log saw a SETUP token ACK'ed,
while on the ftrace, there were endxfer timeouts for all non-control EPs
(due to the dwc3_gadget_stop_active_transfers() call)

Thanks
Wesley

Why did this fail with No Resource? Was it sent before the control TRB
completion?

Are there any specific logs you were looking for?
trace_dwc3_event
trace_dwc3_prepare_trb

Part of reproducing this issue will not allow me to enable tracing, so I
have to make changes in our driver to reroute the logs elsewhere.  So
far I've added changes to do:
	trace_dwc3_ctrl_req
	trace_dwc3_ep_queue
	trace_dwc3_ep_dequeue
	trace_dwc3_gadget_giveback
	trace_dwc3_gadget_ep_cmd

I can add the above 2 tracepoints as well, but wondering if you needed
anything else.

Thanks

Enabled the traces you recommended.  I think it captures it pretty clear
where the status phase was still in progress when the dequeue came in,
which led to the end transfer timeout.  Let me know if you need another log.

Thanks for the trace! I think I see the problem.

The control status isn't completed here.

[ 2181.483069521       0x9dc6445d7]   dbg_ep_dequeue: ep2in: req ffffff879f5a8b00 length 0/63680 zsI ==> -115

But the dequeue may come when host already sent a new Setup packet.
The ep0out hasn't started yet at the point.

Due to various system latency, I can see that this can happen when
the dwc3 driver hasn't received the interrupt notified the status stage
event yet.

If that's the case, the host may have already sent the Setup packet
at this point. So the End Transfer may get stuck if the Setup packet
isn't DMA out yet.

Can you try the change below to see if it resolves the issue?
Code is not tested. Let me know if the logic makes sense. The change is
to delay End Transfer when the Start Transfer for ep0out is completed.

Thanks,
Thinh

Thanks, Thinh.  Sure I'll give it a try with this change.  This is very
similar to the change proposed here as well:

https://lore.kernel.org/linux-usb/20220216000835.25400-3-quic_wcheng@quicinc.com/

One thing to mention is that, I'm not sure how dependable checking soley
the ep0state would be.  I've seen some scenarios where we'd run into the
end transfer timeout during the time between inspecting the SETUP packet
(dwc3_ep0_inspect_setup()) and when the data phase is queued.  The
timing of the data phase can potentially differ if it is a vendor
specific control request.

This is what led me to try w/ marking the endxfer delay after getting a
timed out scenario.  Just something to consider :).  I'll let you know
how it goes!  Thanks again.

Thanks
Wesley Cheng

Not sure if this completely resolves the issue here. The change seems to
issue the End Transfer command before Start Transfer for the next Setup
stage completes. Also it's missing some checks for async calls to the
endpoint that's pending dequeue. Also, we may not need to wait for End
Transfer command to time out if we know the condition to avoid.

This timeout should only apply to Setup packet and Setup stage. Even if
it's vendor specific control request, it should be fine. Host should not
issue a Setup packet until it receives a status stage (unless there's a
disconnect in the middle of a control transfer, but that's a different
issue).

If you do see a problem. We can take a look further.

So far so good w/ the testing.  Had to make a small change in your patch
to fix a typo:
                if (!(dwc3_ep->flags & DWC3_EP_DELAY_STOP))
                        continue;

                dwc3_ep->flags &= ~DWC3_EP_DELAY_STOP;
                ret = dwc3_stop_active_transfer(dwc3_ep, true, true);

Was using dep instead of dwc3_ep.  Will let this run over the weekend
and get back to you.

Thanks

Ok. This seems to confirm my suspicion. Can you update the patch with
the following adjustment:

This is to avoid a case if the function driver has some dependency for
requests to return before sending the control status using delayed
status, which can cause a hang.

We only need to make sure not to issue End Transfer after the status
transfer started and before its completion interrupt, which may prevent
the driver from starting the Setup stage.

Added the above change, and tested it over the weekend and it was
working well for me.  However, I wasn't able to really test the
delayed_status flag too much, since we don't have a function driver that
utilizes the USB_GADGET_DELAYED_STATUS too much. (we only have a FFS
interface, which will do it during enum, which is part of the test case
I ran)

Would it also make sense to check for the dwc->setup_packet_pending flag
as well in the same IF condition?  That would mean that there was a
SETUP packet cached in the controller, which would need to be handled.
I heard from our CC w/ Synopsys that we need to ensure any pending SETUP
packets stored in internal memory needed to be cleared as well before
issuing the endxfer.

This sounds similar to your statement previously about if the SETUP
packet wasn't DMA'ed out yet.

Thanks

Thanks for the test. The delayed status check is only meant for a
special case if the function driver waits for dequeued requests to
return before sending the control status. No function driver is doing
this at the moment, but I want to put the check here anyway for robustness.

Currently the dwc3 driver doesn't handle setup_packet_pending. It only
uses that flag to handle some quirk. It should be fine when it is
implemented (at some point eventually :)).

If the EP0_SETUP_PHASE flag is set, that means that the driver had setup
the TRB for the Setup stage, so the Setup packet can be DMA'ed out
within the End Transfer timeout. When the handling of
setup_packet_pending is implemented, it should properly update the ep0state.

Note: hitting the pending setup packet should be rare. It can happen when
1) Host aborts the control transfer for some reason and start a new one
2) The device is disconnected in the middle of the control transfer

If you plan to implement/handle this scenario, I'll be happy to review
your changes.

Please submit this fix separately from your other RFC patches so it can
go into the driver.

Thanks for the explanation, Thinh.  Let me see if I can revisit the
setup_packet_pending scenario we ran into in the past, and if its still
applicable, I'll submit a separate fix for it.  Its been a few years
since we've seen that :).

Sounds good.  Will take this change outside the RFC series and submit it
to go in.
