Description

This is hrev54703.

_user_process_info(process, PARENT_ID) allows to get parent PID, but it has following check so only current process can get it's parent: ​team.cpp:4002. Check should be removed or applied only if user has no administrator privileges.

This feature is required to implement process view in a tree.

Probably the check can be changed to check if EUID is either the same as the target process' EUID, or the current EUID is 0 (root).

I published my process view utility with process tree: ​SystemManager, ​screenshot. Kernel changes are not yet published.
