Subject: setcap: comment to help the user figure out why setcap is failing. |
|
|
|
The file capabilities are not as expressive as process capabilities |
|
(for a reason - see the NOTES section of 'man 3 cap_set_file'). |
|
|
|
The effective bits on a file under linux are captured by a single |
|
boolean. As such attempting to partially set effective bits via the |
|
more fully expressive process capability representation (cap_from_text) |
|
sometimes yields an error. From now on, suggest that when the user |
|
attempts to do this and an error occurs, the error might be such a |
|
mismatch between effective and the other capability bits. |
