Looking into the archives, it seems that it is a bad idea to read a

file from the filesystem from inside the kernel. However, I couldn't

find anywhere that it's not possible.

In my kext, DTS told me not to do file I/O. I was told to use a log-in app to read configuration settings and pass them to the kext.

The communication between a Kext and an application process involves the

implementation of a UserClient.
