# SPDX-License-Identifier: GPL-2.0-only config SECURITY_TOMOYO bool "TOMOYO Linux Support" depends on SECURITY depends on NET select SECURITYFS select SECURITY_PATH select SECURITY_NETWORK default n help This selects TOMOYO Linux, pathname-based access control. Required userspace tools and further information may be found at <https://tomoyo.osdn.jp/>. If you are unsure how to answer this question, answer N. config SECURITY_TOMOYO_MAX_ACCEPT_ENTRY int "Default maximal count for learning mode" default 2048 range 0 2147483647 depends on SECURITY_TOMOYO 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 SECURITY_TOMOYO_MAX_AUDIT_LOG int "Default maximal count for audit log" default 1024 range 0 2147483647 depends on SECURITY_TOMOYO 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 /sys/kernel/security/tomoyo/audit. If you don't need audit logs, you may set this value to 0. config SECURITY_TOMOYO_OMIT_USERSPACE_LOADER bool "Activate without calling userspace policy loader." default n depends on SECURITY_TOMOYO 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. config SECURITY_TOMOYO_POLICY_LOADER string "Location of userspace policy loader" default "/sbin/tomoyo-init" depends on SECURITY_TOMOYO depends on !SECURITY_TOMOYO_OMIT_USERSPACE_LOADER help This is the default pathname of policy loader which is called before activation. You can override this setting via TOMOYO_loader= kernel command line option. config SECURITY_TOMOYO_ACTIVATION_TRIGGER string "Trigger for calling userspace policy loader" default "/sbin/init" depends on SECURITY_TOMOYO depends on !SECURITY_TOMOYO_OMIT_USERSPACE_LOADER help This is the default pathname of activation trigger. You can override this setting via TOMOYO_trigger= kernel command line option. For example, if you pass init=/bin/systemd option, you may want to also pass TOMOYO_trigger=/bin/systemd option. config SECURITY_TOMOYO_INSECURE_BUILTIN_SETTING bool "Use insecure built-in settings for fuzzing tests." default n depends on SECURITY_TOMOYO select SECURITY_TOMOYO_OMIT_USERSPACE_LOADER help Enabling this option forces minimal built-in policy and disables domain/program checks for run-time policy modifications. Please enable this option only if this kernel is built for doing fuzzing tests.
