Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net: ipa: fix event ring index not programmed for IPA v5.0+<br /> <br /> For IPA v5.0+, the event ring index field moved from CH_C_CNTXT_0 to<br /> CH_C_CNTXT_1. The v5.0 register definition intended to define this<br /> field in the CH_C_CNTXT_1 fmask array but used the old identifier of<br /> ERINDEX instead of CH_ERINDEX.<br /> <br /> Without a valid event ring, GSI channels could never signal transfer<br /> completions. This caused gsi_channel_trans_quiesce() to block<br /> forever in wait_for_completion().<br /> <br /> At least for IPA v5.2 this resolves an issue seen where runtime<br /> suspend, system suspend, and remoteproc stop all hanged forever. It<br /> also meant the IPA data path was completely non functional.
