bin2c was, as its name implies, introduced to convert a binary file to C code. However, I did not see any good reason ever for using this tool because using the .incbin directive is much faster, and often results in simpler code. Most of the uses of bin2c have been killed, for example: -13610aa908("kernel/configs: use .incbin directive to embed config_data.gz") -4c0f032d49("s390/purgatory: Omit use of bin2c") security/tomoyo/Makefile has even less reason for using bin2c because the policy files are text data. So, sed is enough for converting them to C string literals, and what is nicer, generates human-readable builtin-policy.h. This is the last user of bin2c. After this commit lands, bin2c will be removed.

This is the default value for maximal ACL entries

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.

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 option only if this kernel is built for doing fuzzing tests.
