I have a kernel module that receive IP datagram, using netfilter that
pass the datagram to my module.
The kernel module execute some operation and I have the necessity to
pass the results (a string of char essentially) to an application
How I can make? There is someone that has an example of such type of
passage of data?
I have realized the contrary passage (from user-mode to kernel)
registering a sys_call to a function that is implementes in my kernel
There are other mechanisms that make both passages?
