From bc8a45f506a8be33250c523d71fab637a5fdaf81 Mon Sep 17 00:00:00 2001 From: Lajos Molnar Date: Tue, 2 Aug 2016 07:07:05 -0700 Subject: IOMX: work against metadata buffer spoofing - Prohibit direct set/getParam/Settings for extensions meant for OMXNodeInstance alone. This disallows enabling metadata mode without the knowledge of OMXNodeInstance. - Do not share metadata mode buffers cross process. - Disallow setting up metadata mode/tunneling/input surface after first sendCommand. - Disallow store-meta for input cross process. - Disallow emptyBuffer for surface input (via IOMX). - Fix checking for input surface.
