Each resource has an associated soft and hard limit. The soft

||
limit is the value that the kernel enforces for the corresponding

resource. The hard limit acts as a ceiling for the soft limit.
|
||
An unprivileged process may only set its soft limit to a value
|
||
from 0 to the hard limit, and irreversibly lower its hard limit.
