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/>.

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.

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.

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.

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.

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.
