config SECURITY_SELINUX

bool "NSA SELinux Support"
|
|
depends on SECURITY && NET
|
|
default n
|
|
help
|
|
This selects NSA Security-Enhanced Linux (SELinux).
|
|
You will also need a policy configuration and a labeled filesystem.
|
|
You can obtain the policy compiler (checkpolicy), the utility for
|
|
labeling filesystems (setfiles), and an example policy configuration
|
|
from <http://www.nsa.gov/selinux/>.
|
|
If you are unsure how to answer this question, answer N.

config SECURITY_SELINUX_BOOTPARAM

bool "NSA SELinux boot parameter"
|
|
depends on SECURITY_SELINUX
|
|
default n
|
|
help
|
|
This option adds a kernel parameter 'selinux', which allows SELinux
|
|
to be disabled at boot. If this option is selected, SELinux
|
|
functionality can be disabled with selinux=0 on the kernel
|
|
command line. The purpose of this option is to allow a single
|
|
kernel image to be distributed with SELinux built in, but not
|
|
necessarily enabled.
|
|
|
|
If you are unsure how to answer this question, answer N.

config SECURITY_SELINUX_BOOTPARAM_VALUE

range 0 1
|
|
default 1
|
|
help
|
|
This option sets the default value for the kernel parameter
|
|
'selinux', which allows SELinux to be disabled at boot. If this
|
|
option is set to 0 (zero), the SELinux kernel parameter will
|
|
default to 0, disabling SELinux at bootup. If this option is
|
|
set to 1 (one), the SELinux kernel paramater will default to 1,
|
|
enabling SELinux at bootup.
|
|
|
|
If you are unsure how to answer this question, answer 1.

config SECURITY_SELINUX_DISABLE
|
|
bool "NSA SELinux runtime disable"
|
|
depends on SECURITY_SELINUX
|
|
default n
|
|
help
|
|
This option enables writing to a selinuxfs node 'disable', which
|
|
allows SELinux to be disabled at runtime prior to the policy load.
|
|
SELinux will then remain disabled until the next boot.
|
|
This option is similar to the selinux=0 boot parameter, but is to
|
|
support runtime disabling of SELinux, e.g. from /sbin/init, for
|
|
portability across platforms where boot parameters are difficult
|
|
to employ.
|
|
|

If you are unsure how to answer this question, answer N.

config SECURITY_SELINUX_DEVELOP
|
|
bool "NSA SELinux Development Support"
|
|
depends on SECURITY_SELINUX
|
|
default y
|
|
help
|
|
This enables the development support option of NSA SELinux,
|
|
which is useful for experimenting with SELinux and developing
|
|
policies. If unsure, say Y. With this option enabled, the
|
|
kernel will start in permissive mode (log everything, deny nothing)
|
|
unless you specify enforcing=1 on the kernel command line. You
|
|
can interactively toggle the kernel between enforcing mode and
|
|
permissive mode (if permitted by the policy) via /selinux/enforce.

config SECURITY_SELINUX_MLS

bool "NSA SELinux MLS policy (EXPERIMENTAL)"

|
|
default n
|
|
help
|
|
This enables the NSA SELinux Multi-Level Security (MLS) policy in
|
|
addition to the default RBAC/TE policy. This policy is
|
|
experimental and has not been configured for use. Unless you
|
|
specifically want to experiment with MLS, say N.
