Can eBPF be used to modify the list of WiFi networks visible to the user via NetworkManager? Hide some of them, add or modify info of the others....

Or even better, modify it on yet the lower level such that any application that polls the list via system API would receive a modified list.

The is about eBPF only

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?

Intel seems to have gotten "inspired" by ARM and is going to double the GP registers to 32 and implement a push2 and pop2 instructions that move two register values in one operation.

Seems interesting enough.

Recently riscv64 support has been merged in the 5.0 release, perfectly in time for me having time to get back into a project again. I'll be posting a barebones example soon since there is only one for x86.
