Descripción
*** Pendiente de traducción *** 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.
