Or messages like: [ 395.090938] usb 1-1: Failed to create links for entity 5 [ 395.091385] usb 1-1: Failed to register entities (-22). Otherwise, it might just be that your kernel is not built with CONFIG_MEDIA_CONTROLLER. I reached that conclusion by emulating a similar uvc device. Yours has the entity ID for both the output terminal and processing unit. Though that is not valid according to the spec (even UVC 1.0 mentions the IDs should be unique), we should keep supporting such devices. I am currently working on a fix that will restore support for your device but improve its support for configs with CONFIG_MEDIA_CONTROLLER. I appreciate your help on testing such configurations and fixes. Thanks. Cascardo. ^ permalink raw reply [flat|nested] 24+ messages in thread

If multiple entities have the same id then they cannot be part of the topology, because we will never be sure about what entity is the correct one. My proposal is to mark the duplicated as invalid so they cannot be found with uvc_entity_by_id(), but they can still have controls. I think it can work with multiple duplicated IDs. It is also pretty clean and is not affected by the issue found by syszcaller. In any case we probably want to act fast on this one. We had reports from multiple parties.

Tomasz has reported that his device, Generalplus Technology Inc. 808 Camera, with ID 1b3f:2002, stopped being detected: $ ls -l /dev/video* zsh: no matches found: /dev/video* [ 7.230599] usb 3-2: Found multiple Units with ID 5 This particular device is non-compliant, having both the Output Terminal and Processing Unit with ID 5. uvc_scan_fallback, though, is able to build a chain. However, when media elements are added and uvc_mc_create_links call uvc_entity_by_id, it will get the incorrect entity, media_create_pad_link will WARN, and it will fail to register the entities. In order to reinstate support for such devices in a timely fashion, reverting the fix for these warnings is appropriate. A proper fix that considers the existence of such non-compliant devices will be submitted in a later development cycle.

Since both you (Ricardo) and Laurant seemed to be on top of this I didn't take a closer look yet. But this definitely is hitting users and we need to fix this.

As we're in the middle of the merge window, the patch couldn't be merged right away. I'm also fine if Mauro picks it up, that's easier for me. If it hasn't been merged in the fixes branch on Monday, I'll send the pull request. -- Regards, Laurent Pinchart ^ permalink raw reply [flat|nested] 24+ messages in thread

But now, we know this same failure may happen with real devices. uvc_mc_create_links will use baSourceID to find an entity on the list, but since there may be multiple entities with the same ID, it may find the incorrect one (in this case, finding the output terminal instead of the processing unit). > > pointers to the entities instead of only their IDs. > > Missing SoB and Fixes tags. > I skipped them on purpose since this was an RFC. > The commit message should explain why this is better than reverting > 3dd075fe8ebb ("media: uvcvideo: Require entities to have a non-zero > unique ID").

I am trying to balance here between changing the code too much, which could lead to other hardware stop working and fixing the two bugs. We could replace baSourceID array with the source_entities array entirely. But while the baSourceID is built from the USB descriptors, the source_entities rely on the building of the chain. And using baSourceID to find the entities in unreliable because of these devices with multiple entities with the same ID. Perhaps we should skip when source_entities[i] is NULL, which indicates that we could not build the chain. But then, again, this introduces more risk of regressing other hardware, at least without further analysis.
