Subject: [PATCH v6 0/4] usb: gadget: uvc: stability fixes on STREAMOFF.
Date: Thu, 19 Oct 2023 11:53:15 -0700 [thread overview]
Message-ID: <20231019185319.2714000-1-arakesh@google.com> (raw)
In-Reply-To: <20230930184821.310143-1-arakesh@google.com>
We have been seeing two main stability issues that uvc gadget driver
runs into when stopping streams:
1. Attempting to queue usb_requests to a disabled usb_ep
2. use-after-free issue for inflight usb_requests
The four patches below fix the two issues above. Patch 1/4 fixes the
first issue, and Patch 2/4 and 4/4 fix the second issue. Patch 3/4
is only there to make the diff in 4/4 cleaner.
Avichal Rakesh (4):
usb: gadget: uvc: prevent use of disabled endpoint
usb: gadget: uvc: Allocate uvc_requests one at a time
usb: gadget: uvc: move video disable logic to its own function
usb: gadget: uvc: Fix use-after-free for inflight usb_requests
