Thank you for your explanation. i understand that i can jst write a driver, however, I just want to see if there's a way that already exist for developer to call or use at the app level or library or framework level so that we can securely transmit data to kernel Well because I am a newbie for

simple solution would be to just create a stream interface based driver and write to it whatever you want to. If you want to actually do some key\secret exchange, implement some ioctl calls for itbut again, i think you should do your data manipulation in app layer and then just send that data t

yea you can say that as "encrypted channel" I just want to study how Applications now use what kind of functions or ways to transmit data to kernel so probably later I can try to write my own "channel" so that application can bypass "Library" and "Application Framework" level any idea? On Oct

Did you build the module against your new kernel? (i.e. ARCH=arm KERNEL_DIR=/kernel make). I've encountered that error message before and it seems that the booted kernel still do not allow "Enable Loadable Module" .config support. Are you sure emulator is booted with the new kernel? (i.e. emulator
