Hi all, I'm writing a module which restrict some user space operations, and I'd like to restrict the access to some sensitive kernel data structures or kernel memory region. The main idea is to grant the access to these known addresses with one kind of authentication, key or signature. Obviously the authentication request is focused on kernel modules only. I'm not so expert in kernel module programming so I don't know if it's possible [and how] to do it via kernel module. any suggestion or reference will be appreciated thank you in advance.
