config CCSECURITY
        bool "CCSecurity support"
        default y
        help
          Say Y here to support non-LSM version of TOMOYO Linux.
          http://tomoyo.sourceforge.jp/

config CCSECURITY_LKM
        bool "Compile as loadable kernel module"
        default n
        depends on CCSECURITY && MODULES
        help
          This version of TOMOYO depends on patching the kernel source in order
          to insert some hooks which LSM does not provide. Therefore,
          recompiling the kernel is inevitable. But if you want to keep
          vmlinux's size as small as possible, you can compile most part of
          TOMOYO as a loadable kernel module by saying Y here.

config CCSECURITY_DISABLE_BY_DEFAULT
        bool "Disable by default"
        default n
        depends on CCSECURITY
        help
          Say Y here if you want TOMOYO disabled by default.
          To enable TOMOYO, pass ccsecurity=on to kernel command line.
          To disable TOMOYO, pass ccsecurity=off to kernel command line.

config CCSECURITY_USE_EXTERNAL_TASK_SECURITY
        bool "Do not modify 'struct task_struct' in order to keep KABI"
        default n
        depends on CCSECURITY
        help
          Say Y here if you want to keep KABI for prebuilt kernel modules
          unchanged. TOMOYO needs "struct ccs_domain_info *" and "u32" for each
          "struct task_struct". But embedding these variables into
          "struct task_struct" breaks KABI for prebuilt kernel modules (which
          means that you will need to rebuild prebuilt kernel modules).
          If you say Y here, these variables are managed outside
          "struct task_struct" rather than embedding into "struct task_struct",
          but accessing these variables becomes slower because lookup operation
          is performed every time the current thread needs to access them.

config CCSECURITY_MAX_ACCEPT_ENTRY
        int "Default maximal count for learning mode"
        default 2048
        range 0 2147483647
        depends on CCSECURITY
        help
          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.

config CCSECURITY_MAX_AUDIT_LOG
        int "Default maximal count for audit log"
        default 1024
        range 0 2147483647
        depends on CCSECURITY
        help
          This is the default value for maximal entries for
          audit logs that the kernel can hold on memory.
          You can read the log via /proc/ccs/audit.
          If you don't need audit logs, you may set this value to 0.

config CCSECURITY_OMIT_USERSPACE_LOADER
        bool "Activate without calling userspace policy loader."
        default n
        depends on CCSECURITY
        ---help---
          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.

          If you say Y to both "Compile as loadable kernel module" option and
          "Activate without calling userspace policy loader." option, be sure
          to excplicitly load the kernel module from the userspace, for
          the kernel will not call /sbin/ccs-init when /sbin/init starts.

config CCSECURITY_POLICY_LOADER
        string "Location of userspace policy loader"
        default "/sbin/ccs-init"
        depends on CCSECURITY
        depends on !CCSECURITY_OMIT_USERSPACE_LOADER
        ---help---
          This is the default pathname of policy loader which is called before
          activation. You can override this setting via CCS_loader= kernel
          command line option.

config CCSECURITY_ACTIVATION_TRIGGER
        string "Trigger for calling userspace policy loader"
        default "/sbin/init"
        depends on CCSECURITY
        depends on !CCSECURITY_OMIT_USERSPACE_LOADER
        ---help---
          This is the default pathname of activation trigger.
          You can override this setting via CCS_trigger= kernel command line
          option. For example, if you pass init=/bin/systemd option, you may
          want to also pass CCS_trigger=/bin/systemd option.
