-config SECURITY_SELINUX_ENABLE_SECMARK_DEFAULT
- bool "NSA SELinux enable new secmark network controls by default"
- depends on SECURITY_SELINUX
- default n
- help
- This option determines whether the new secmark-based network
- controls will be enabled by default. If not, the old internal
- per-packet controls will be enabled by default, preserving
- old behavior.
-
- If you enable the new controls, you will need updated
- SELinux userspace libraries, tools and policy. Typically,
- your distribution will provide these and enable the new controls
- in the kernel they also distribute.
-
- Note that this option can be overriden at boot with the
- selinux_compat_net parameter, and after boot via
- /selinux/compat_net. See Documentation/kernel-parameters.txt
- for details on this parameter.
-
- If you enable the new network controls, you will likely
- also require the SECMARK and CONNSECMARK targets, as
- well as any conntrack helpers for protocols which you
- wish to control.

- If you are unsure what do do here, select N.

-config SECURITY_SELINUX_POLICYDB_VERSION_MAX
- bool "NSA SELinux maximum supported policy format version"
- depends on SECURITY_SELINUX
- default n
- help
- This option enables the maximum policy format version supported
- by SELinux to be set to a particular value. This value is reported
- to userspace via /selinux/policyvers and used at policy load time.
- It can be adjusted downward to support legacy userland (init) that
- does not correctly handle kernels that support newer policy versions.
-
- Examples: For FC3 or FC4, enable this option and set the value via
- the next option. For FC5 and later, do not enable this option.
-
- If you are unsure how to answer this question, answer N.

-config SECURITY_SELINUX_POLICYDB_VERSION_MAX_VALUE
- int "NSA SELinux maximum supported policy format version value"
- depends on SECURITY_SELINUX_POLICYDB_VERSION_MAX
- range 15 21
- default 19
- help
- This option sets the value for the maximum policy format version
- supported by SELinux.
-
- Examples: For FC3, use 18. For FC4, use 19.
-
- If you are unsure how to answer this question, look for the
- policy format version supported by your policy toolchain, by
- running 'checkpolicy -V'. Or look at what policy you have
- installed under /etc/selinux/$SELINUXTYPE/policy, where
- SELINUXTYPE is defined in your /etc/selinux/config.
