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.

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. -- Timur Tabi Staff Software Engineer timur.tabi@xxxxxxxxxxx -- Kernelnewbies: Help each other learn about the Linux kernel.
