Build apparmor with debugging logic in apparmor. Not all

Enable code assertions made with AA_BUG. These are primarily

function entry preconditions but also exist at other key

message.

This option selects whether introspection of loaded policy
|
|
is available to userspace via the apparmor filesystem. This
|
|
adds to kernel memory usage. It is required for introspection
|
|
of loaded policy, and check point and restore support. It
|

can be disabled for embedded systems where reducing memory and

cpu is paramount.

This option selects whether introspection of loaded policy

This option selects whether sha1 hashing of loaded policy
|

is enabled by default. The generation of sha1 hashes for
|
|
loaded policy provide system administrators a quick way
|
|
to verify that policy in the kernel matches what is expected,
|
|
however it can slow down policy load on some devices. In
|
|
these cases policy hashing can be disabled by default and

enabled only if needed.

This option allows reading back binary policy as it was loaded.

It increases the amount of kernel memory needed by policy and

also increases policy load time. This option is required for

checkpoint and restore support, and debugging of loaded policy.

This options allows controlling whether apparmor does a full

|
verification of loaded policy. This should not be disabled
|
|
except for embedded systems where the image is read only,

includes policy, and has some form of integrity check.

Disabling the check will speed up policy loads.

This builds the AppArmor KUnit tests.

KUnit tests run during boot and output the results to the debug log

running KUnit test harness and are not for inclusion into a

production build.
