Hi David, >From the man page: > Only validly signed modules may be loaded. > .P > Only validly signed binaries may be kexec'd. > .P > Only validly signed device firmware may be loaded. fw_get_filesystem_firmware() calls kernel_read_file_from_path() to read the firmware, which calls into the security hooks. Is there another place that validates the firmware signatures. I'm not seeing which patch requires firmware to be signed?
