config SECURITY_SELINUX
bool "NSA SELinux Support"
depends on SECURITY_NETWORK && AUDIT && NET && INET
select NETWORK_SECMARK
default n
help
This selects NSA Security-Enhanced Linux (SELinux).
You will also need a policy configuration and a labeled filesystem.
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
int "NSA SELinux boot parameter default value"
depends on SECURITY_SELINUX_BOOTPARAM
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 parameter 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_AVC_STATS
bool "NSA SELinux AVC Statistics"
depends on SECURITY_SELINUX
default y
help
This option collects access vector cache statistics to
/selinux/avc/cache_stats, which may be monitored via
tools such as avcstat.
config SECURITY_SELINUX_CHECKREQPROT_VALUE
int "NSA SELinux checkreqprot default value"
depends on SECURITY_SELINUX
range 0 1
default 0
help
This option sets the default value for the 'checkreqprot' flag
that determines whether SELinux checks the protection requested
by the application or the protection that will be applied by the
kernel (including any implied execute for read-implies-exec) for
mmap and mprotect calls. If this option is set to 0 (zero),
SELinux will default to checking the protection that will be applied
by the kernel. If this option is set to 1 (one), SELinux will
default to checking the protection requested by the application.
The checkreqprot flag may be changed from the default via the
'checkreqprot=' boot parameter. It may also be changed at runtime
via /selinux/checkreqprot if authorized by policy.
If you are unsure how to answer this question, answer 0.
