apparmor: clarify CRYPTO dependency The crypto framework can be built as a loadable module, but the apparmor hash code can only be built-in, which then causes a link error: security/built-in.o: In function `aa_calc_profile_hash': integrity_audit.c:(.text+0x21610): undefined reference to `crypto_shash_update' security/built-in.o: In function `init_profile_hash': integrity_audit.c:(.init.text+0xb4c): undefined reference to `crypto_alloc_shash' This changes Apparmor to use 'select CRYPTO' like a lot of other subsystems do.

is available to userspace via the apparmor filesystem.
config SECURITY_APPARMOR_HASH_DEFAULT
bool "Enable policy hash introspection by default"
depends on SECURITY_APPARMOR_HASH
default y
help
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.

debugging logic will necessarily be enabled. A submenu will
provide fine grained control of the debug options that are
available.

Enable code assertions made with AA_BUG. These are primarily
function entry preconditions but also exist at other key
points. If the assert is triggered it will trigger a WARN
message.

Set the default value of the apparmor.debug kernel parameter.
When enabled, various debug messages will be logged to
the kernel message buffer.
apparmor: add AppArmor KUnit tests for policy unpack Add KUnit tests to test AppArmor unpacking of userspace policies. AppArmor uses a serialized binary format for loading policies. To find policy format documentation see Documentation/admin-guide/LSM/apparmor.rst. In order to write the tests against the policy unpacking code, some static functions needed to be exposed for testing purposes. One of the goals of this patch is to establish a pattern for which testing these kinds of functions should be done in the future.

help
This builds the AppArmor KUnit tests.
KUnit tests run during boot and output the results to the debug log
in TAP format (http://testanything.org/). Only useful for kernel devs
running KUnit test harness and are not for inclusion into a
production build.
For more information on KUnit and unit tests in general please refer
to the KUnit documentation in Documentation/dev-tools/kunit/.
If unsure, say N.
