quicktime_video_hack Not receiving CWPA Message

My objective is to replicate your project on C++. I'm currently on Ubuntu 20.10 with libusb 1.0.23. I've managed so far to enable the hidden QT-Config, to receive the PING message from the device and to send the PING message back. Unfortunately, the device never sends anything after that. According to the technical description there should be a SYNC-CWPA message.

The device is a recent iPhone SE with iOS 13.7

The same thing seems to happen with your code, I've tried both with docker and with locally built version.

Running docker with:

docker run --privileged -v /dev/bus/usb:/dev/bus/usb -it qvhrun:$(git branch --show-current) bash

The output is:

Running locally seems to be work slightly better.

but it still stops at the same point as my c++ code.

I guess there's something missing. Unfortunately I don't have a Mac to debug the real exchange between quicktime and the device.

BTW, in the technical documentation, the HPD1 and the HPA1 messages are not documented.

Dec 14 '20 22:12 j-santander

Hey Julian! Cool stuff! :-D Out of curiosity, may I ask what your planning to do with the tool? Is it just for fun or are you planning to do something with it professionally?

I definitely need to spend some time figuring out a few improvements for Linux support, that is long overdue. Have you tried disabling the built-in ubuntu usbmux?

It is interesting that it does not work for you, usually when the PING is received everything works just fine.

Can you run qvh diagnostics metrics.csv --dump=binary.bin and check the binary dump of the usb transferred data?

Kudos for uncovering that I forgot to document these messages, I'll do it on the weekend. I will also try to test the tool with my iPhones and tablets again to give some better explanations how to use this on Linux.

Dec 15 '20 06:12 danielpaulus

Hi @danielpaulus. thanks. Well, my intent is professional: we're adding support for iOS devices on a test probe.

Just executed the command you indicated, the output:

xxd inbound-binary.bin:

00000000: 676e 6970 0000 0000 0100 0000            gnip........

xxd outbound-binary.bin:

00000000: 1000 0000 676e 6970 0000 0000 0100 0000  ....gnip........

00000030: 0000 0000 3064 7068

Note that this is on a freshly connected device. If I run it a second time, the error I get is:

{"level":"warning","msg":"Error opening usb deviceslibusb: bad access [code -3]","time":"2020-12-15T07:39:04+01:00"}

{"level":"info","msg":"Stopped","time":"2020-12-15T07:39:04+01:00"}

I just realized this is similar to what is described in #37

The zip contains the inbound-binary.bin, the outbound-binary.bin and logfile-1608014449.log output.zip

Please let me know if I can test anything else from my side.

Dec 15 '20 06:12 j-santander

disabling usbmuxd (masking it as described in #37) changes slightly the behaviour:

When running first time after connecting the device. It is the same, flow stops after receiving & sending the PING message.
When running second time, then it does not receive the PING:

My guess is that there are two separate problems:

There's a conflict with system processes in linux trying to get hold of the device. As an aside, in my c++ code I'm taking measures to detach the device from kernel drivers before trying to claim the interface (most of the times it works, when it fails there's an API to reset the device and I try again). Now, this is my first exposure to talking to USB devices, so it might not be the right thing to do,
Either something has changed in the message sequence or we're missing something. As I said, I don't have any experience with libusb so I proceeded slowly adding pieces progressively to my code. What it seems is that device seems to get stuck in an odd state (e.g. the device does not send PING when connected again).

Dec 15 '20 07:12 j-santander

usbmuxd will always force the device to configuration 4, even if 5 configurations are available: https://github.com/libimobiledevice/usbmuxd/blob/master/src/usb.c#L396-L399. It will also claim the usbmux interfaces; calling set_configuration from another program will result in EBUSY.

You'll have to patch usbmuxd for this to work.

Yes, in some scenarios, the device does not detect you disconnected from the Valeria interface (e.g. if you didn't properly send the stop packets). You can always reset the device by physically disconnecting it and reconnecting it again.

ok, thanks for the reference to the patch. As I said, in my C++ code it seems I can work around that by detaching drivers and releasing interfaces and if everything fails requesting the device to reset before trying again.

However, the issue of not receiving the CWPA after the PING seems to be present with and without the usbmuxd and it is also present in freshly connected devices.

Dec 15 '20 09:12 j-santander

For the record. I'm making progress in my port to C++, already capturing audio and video.

For me, the key was what @qmfrederik indicated. It seems that usbmuxd requires the patch linked in the comment. Patching and recompiling usbmuxd, made the project working correctly (and from there I was able to continue with my C++ port).

So the situation seems to be:

With unpatched usbmuxd, it doesn't work because usbmuxd interferes with setting the configuration and claiming the interfaces.
With patched usbmuxd. It works. We see the PING and the CWPA.
Without usbmuxd (masking or what I was doing to reset the device), it doesn't work (missing CWPA).

To me, this indicates that some part of the flurry of messages that usbmuxd exchanges, is required for the QT interface to work.

I'll keep looking into this. In my target environmen I'm not sure even if I will have usbmuxd available and deploying a patched version might be a big hassle.

If I'm not mistaken, usbmuxd starts a Lockdown session. This allows the host to authenticate to the device (e.g. making it 'trusted'). I think that this is required for the AV interface to work. In other words, the AV interface does not work if the host has not established a trust relationship with the device

With unpatched usbmuxd, it doesn't work because usbmuxd interferes with setting the configuration and claiming the interfaces.

usbmuxd just got patched: https://github.com/libimobiledevice/usbmuxd/commit/bf2e2ec054102286ad6ab272be42c21034c136ed, see libimobiledevice/usbmuxd#160 for the discussion

successed on iphone 8 ,iphone xs,but still can not get CWPA on iphone 11 and iphone 12 with patched usbmuxd
