Hello, very simple question.
Once OpenWrt is installed on a supported device does the device run completely on open source code or is it still left with some proprietary blob from the original vendor?
OpenWrt replaces kernel and rootfs, the OEM bootloader usually remains (exceptions exist, e.g. the belkin rt3200 or some lantiq devices), as do some 'data' partitions (such as wifi calibration data).

What would be the privacy implications of this? Is it possible for the device to be still calling back the original vendor?
The bootloader 'should' cease control over the system once it hands over to the kernel (although one can never be 100% sure with ARM trusted environment) and usually it doesn't have internet access (although it could).
