- bool "Enable the /proc/keys file by which keys may be viewed"
- depends on KEYS
- help
- This option turns on support for the /proc/keys file - through which
- can be listed all the keys on the system that are viewable by the
- reading process.
-
- The only keys included in the list are those that grant View
- permission to the reading process whether or not it possesses them.
- Note that LSM security checks are still performed, and may further
- filter out keys that the current process is not authorised to view.
-
- Only key attributes are listed here; key payloads are not included in
- the resulting table.
