| |
If I have a PID and some GID at hand, how do I find whether the OHTER process identified by PID has the GID in its supplementary set of groups?
I can find the "in_group_p" test, but that does it only for current process.
Do I have to write my own function that uses the "tasklist_lock", finds task by "find_task_by_pid", and then calls "groups_search(task->group_info, gid)"?
Can I do this in a module, or do I have to patch the "kernel/sys.c" myself for a privately modified version of the kernel?
