[PATCH 1/2] media: streamzap: fix race between device disconnection and urb callback

by Murad Masimov

Syzkaller has reported a general protection fault at function ir_raw_event_store_with_filter(). This crash is caused by a NULL pointer dereference of dev->raw pointer, even though it is checked for NULL in the same function, which means there is a race condition. It occurs due to the incorrect order of actions in the streamzap_disconnect() function: rc_unregister_device() is called before usb_kill_urb(). The dev->raw pointer is freed and set to NULL in rc_unregister_device(), and only after that usb_kill_urb() waits for in-progress requests to finish. If rc_unregister_device() is called while streamzap_callback() handler is not finished, this can lead to accessing freed resources. Thus rc_unregister_device() should be called after usb_kill_urb(). Found by Linux Verification Center (linuxtesting.org) with Syzkaller.

This means that even when the cable is unplugged, the orientation propagated to the switches along the graph is "orientation normal", instead of "orientation none", which would be the correct one in this case. One of the Qualcomm DP-USB PHY combo drivers, which needs to be aware of the orientation change, is relying on the "orientation none" to skip the reinitialization of the entire PHY. Since the ucsi glink client advertises "orientation normal" even when the cable is unplugged, the mentioned PHY is taken down and reinitialized when in fact it should be left as-is. This triggers a crash within the displayport controller driver in turn, which brings the whole system down on some Qualcomm platforms. Propagating "orientation none" from the ucsi glink client on the connector_status() callback hides the problem of the mentioned PHY driver away for now. But the "orientation none" is nonetheless the correct one to be used in this case. So propagate the "orientation none" instead when the connector status flags says cable is disconnected.
