This is the default value for maximal ACL entries
|
|
that are automatically appended into policy at "learning mode".
|
|
Some programs access thousands of objects, so running
|
|
such programs in "learning mode" dulls the system response
|
|
and consumes much memory.
|
|
This is the safeguard for such programs.

You can read the log via /sys/kernel/security/tomoyo/audit.

Say Y here if you want to activate access control as soon as built-in
|
|
policy was loaded. This option will be useful for systems where
|
|
operations which can lead to the hijacking of the boot sequence are
|
|
needed before loading the policy. For example, you can activate
|
|
immediately after loading the fixed part of policy which will allow
|
|
only operations needed for mounting a partition which contains the
|
|
variant part of policy and verifying (e.g. running GPG check) and
|
|
loading the variant part of policy. Since you can start using
|
|
enforcing mode from the beginning, you can reduce the possibility of
|
|
hijacking the boot sequence.

This is the default pathname of activation trigger.

You can override this setting via TOMOYO_trigger= kernel command line
|

option. For example, if you pass init=/bin/systemd option, you may
|
|
want to also pass TOMOYO_trigger=/bin/systemd option.
