RE: Can a driver give root privileges to a process?

["Dhiman, Gaurav" <Gaurav.Dhiman@xxxxxx>]

I hope, if you change the "uid" or "euid" (not sure which one) in
"task_struct" of current process to the uid of root, you process will
have root privileges. This is what "login" user program do, using set
_uid systemcall.

There are specific significance of uid, euid, suid fields in
task_struct, before modifying them, do check there significance.

I might be wrong, not sure about it, if I am wrong, please correct me.

Regards,
Gaurav

I know I need to consider the security issues before delivering the 
product, but I want to at least explore the option first.

However, I was hoping you would tell me HOW I give root privileges to a 
process from a driver.
