Required userspace tools (if they are not included in your distribution) and further information may be found at http://apparmor.wiki.kernel.org If you are unsure how to answer this question, answer N. config SECURITY_APPARMOR_DEBUG bool "Build AppArmor with debug code" depends on SECURITY_APPARMOR default n help Build apparmor with debugging logic in apparmor. Not all debugging logic will necessarily be enabled. A submenu will provide fine grained control of the debug options that are available. config SECURITY_APPARMOR_DEBUG_ASSERTS bool "Build AppArmor with debugging asserts" depends on SECURITY_APPARMOR_DEBUG default y help 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. config SECURITY_APPARMOR_DEBUG_MESSAGES bool "Debug messages enabled by default" depends on SECURITY_APPARMOR_DEBUG default n help Set the default value of the apparmor.debug kernel parameter. When enabled, various debug messages will be logged to the kernel message buffer. config SECURITY_APPARMOR_INTROSPECT_POLICY bool "Allow loaded policy to be introspected" depends on SECURITY_APPARMOR default y help 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. config SECURITY_APPARMOR_HASH bool "Enable introspection of sha1 hashes for loaded profiles" depends on SECURITY_APPARMOR_INTROSPECT_POLICY select CRYPTO select CRYPTO_SHA1 default y help This option selects whether introspection of loaded policy hashes is available to userspace via the apparmor filesystem. This option provides a light weight means of checking loaded policy. This option adds to policy load time and can be disabled for small embedded systems. 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. config SECURITY_APPARMOR_EXPORT_BINARY bool "Allow exporting the raw binary policy" depends on SECURITY_APPARMOR_INTROSPECT_POLICY select ZSTD_COMPRESS select ZSTD_DECOMPRESS default y help 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. config SECURITY_APPARMOR_PARANOID_LOAD bool "Perform full verification of loaded policy" depends on SECURITY_APPARMOR default y help 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. config SECURITY_APPARMOR_KUNIT_TEST tristate "Build KUnit tests for policy_unpack.c" if !KUNIT_ALL_TESTS depends on KUNIT && SECURITY_APPARMOR default KUNIT_ALL_TESTS help This builds the AppArmor KUnit tests. KUnit tests run during boot and output the results to the debug log in TAP format (https://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. |
