[PATCH] ASoC: SOF: ipc4-topology: Free the ida when IPC fails in sof_ipc4_widget_setup()
by Peter Ujfalusi 21 Sep '22

21 Sep '22

The allocated ida needs to be freed up if the IPC message fails since next time when we try again to set up the widget we are going to try to allocate another ID and given enough tries, we are going to run out of unique IDs.

possible deadlock in snd_rawmidi_free
by Rondreis 21 Sep '22

21 Sep '22

Hello, When fuzzing the Linux kernel driver v6.0-rc4, the following crash was triggered. HEAD commit: 7e18e42e4b280c85b76967a9106a13ca61c16179 git tree: upstream kernel config: https://pastebin.com/raw/xtrgsXP3 console output: https://pastebin.com/raw/9tabWDtu Sorry for failing to extract the reproducer, and the crash occurred at the moment of disconnecting the midi device. On other versions of Linux, I also triggered this crash. I would appreciate it if you have any idea how to solve this bug. The crash report is as follows: ====================================================== WARNING: possible circular locking dependency detected 6.0.0-rc4+ #20 Not tainted
