Even with the proposed approach, the kernel sits in the middle between the module and user space. As such, it can maintain an "allow list" that only allows access to modules with a specific memory map (CMIS and SFF-8636 for now) and only to a subset of the pages which are standardized by the specifications.Hi Ido This seems like a reasonable compromise. But i would go further. Limit it to just what is needed for firmware upgrade. Andrew
Hello! If this is just because for CMIS firmware upgrade, what about rather providing kernel driver for CMIS firmware upgrade?
