Resource Control Values and Privilege Levels

Each threshold value on a resource control must be associated with one of the following privilege levels:

RCPRIV_BASIC

Privilege level can be modified by the owner of the calling process. RCPRIV_BASIC is associated with a resource's soft limit.

RCPRIV_PRIVILEGED

Privilege level can be modified only by privileged (superuser) callers. RCPRIV_PRIVILEGED is associated with a resource's hard limit.

RCPRIV_SYSTEM

Privilege level remains fixed for the duration of the operating system instance.

Figure 5–2 shows the timeline for setting privilege levels for signals that are defined by the /etc/project file process.max-cpu-time resource control.
