I want to take aт existing, a standard or one of the popular ones, WiFi driver for Linux and tweak it. I'll inroduce a whitelist into it. That is, to the consumer a driver will show the networks from a whitelist only ignoring all other ones.

It's a PoC. I want to implement it as simply as possible.

Can this be implemented? And how, in a high level?

Well here's the AP scan code for the Intel WiFi driver: https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/iwlwifi-fixes.git/tree/net/wireless/scan.c

Go though the occurrences of SSID and decide whether you need to add some code to check it before continuing for each one.

Then you can either compile a whole new kernel, or setup dkms to dynamically load the module in.
