sestatus(8) SELinux command line documentation sestatus(8)NAME
sestatus - SELinux status tool
SYNOPSIS
sestatus [-v] [-b]
This tool is used to get the status of a system running SELinux.
DESCRIPTION
This manual page describes the sestatus program.
This tool is used to get the status of a system running SELinux. It displays data about whether SELinux is enabled or disabled, location of
key directories, and the loaded policy with its status as shown in the example:
> sestatus
SELinux status: enabled
SELinuxfs mount: /selinux
SELinux root directory: /etc/selinux
Loaded policy name: targeted
Current mode: permissive
Mode from config file: enforcing
Policy MLS status: enabled
Policy deny_unknown status: allow
Max kernel policy version: 26
sestatus can also be used to display:
- The security context of files and processes listed in the /etc/sestatus.conf file. The format of this file is described in ses-
tatus.conf(5).
- The status of booleans.
OPTIONS -v
Displays the contexts of files and processes listed in the /etc/sestatus.conf file. It also checks whether the file is a symbolic
link, if so then the context of the target file is also shown.
The following contexts will always be displayed:
The current process context
The init process context
The controlling terminal file context
-b
Display the current state of booleans.

selinux_config(5) SELinux configuration file selinux_config(5)NAME
config - The SELinux sub-system configuration file.
DESCRIPTION
The SELinux config file controls the state of SELinux regarding:
1. The policy enforcement status - enforcing, permissive or disabled.
2. The policy name or type that forms a path to the policy to be loaded and its supporting configuration files.
3. How local users and booleans will be managed when the policy is loaded (note that this function was used by older releases of
SELinux and is now deprecated).
4. How SELinux-aware login applications should behave if no valid SELinux users are configured.
5. Whether the system is to be relabeled or not.
The entries controlling these functions are described in the FILE FORMAT section.
The fully qualified path name of the SELinux configuration file is /etc/selinux/config.
If the config file is missing or corrupt, then no SELinux policy is loaded (i.e. SELinux is disabled).
The sestatus (8) command and the libselinux function selinux_path (3) will return the location of the config file.
FILE FORMAT
The config file supports the following parameters:
SELINUX = enforcing | permissive | disabled
SELINUXTYPE = policy_name
SETLOCALDEFS = 0 | 1
REQUIREUSERS = 0 | 1
AUTORELABEL = 0 | 1
Where:
SELINUX
This entry can contain one of three values:
enforcing
SELinux security policy is enforced.
permissive
SELinux security policy is not enforced but logs the warnings (i.e. the action is allowed to proceed).
disabled
SELinux is disabled and no policy is loaded.
The entry can be determined using the sestatus(8) command or selinux_getenforcemode(3).
SELINUXTYPE
The policy_name entry is used to identify the policy type, and becomes the directory name of where the policy and its configuration
files are located.
The entry can be determined using the sestatus(8) command or selinux_getpolicytype(3).
The policy_name is relative to a path that is defined within the SELinux subsystem that can be retrieved by using selinux_path(3).
An example entry retrieved by selinux_path(3) is:
/etc/selinux/
The policy_name is then appended to this and becomes the 'policy root' location that can be retrieved by selinux_pol-
icy_root_path(3). An example entry retrieved is:
/etc/selinux/targeted
The actual binary policy is located relative to this directory and also has a policy name pre-allocated. This information can be
retrieved using selinux_binary_policy_path(3). An example entry retrieved by selinux_binary_policy_path(3) is:
/etc/selinux/targeted/policy/policy
The binary policy name has by convention the SELinux policy version that it supports appended to it. The maximum policy version sup-
ported by the kernel can be determined using the sestatus(8) command or security_policyvers(3). An example binary policy file with
the version is:
/etc/selinux/targeted/policy/policy.24
SETLOCALDEFS
This entry is deprecated and should be removed or set to 0.
If set to 1, then selinux_mkload_policy(3) will read the local customisation for booleans (see booleans(5)) and users (see
local.users(5)).
REQUIRESEUSERS
This optional entry can be used to fail a login if there is no matching or default entry in the seusers(5) file or if the seusers
file is missing.
It is checked by getseuserbyname(3) that is called by SELinux-aware login applications such as PAM(8).
If set to 0 or the entry missing:
getseuserbyname(3) will return the GNU / Linux user name as the SELinux user.
If set to 1:
getseuserbyname(3) will fail.
The getseuserbyname(3) man page should be consulted for its use. The format of the seusers file is shown in seusers(5).
AUTORELABEL
This is an optional entry that allows the file system to be relabeled.
If set to 0 and there is a file called .autorelabel in the root directory, then on a reboot, the loader will drop to a shell where a
root login is required. An administrator can then manually relabel the file system.
If set to 1 or no entry present (the default) and there is a .autorelabel file in the root directory, then the file system will be
automatically relabeled using fixfiles -F restore
In both cases the /.autorelabel file will be removed so that relabeling is not done again.
EXAMPLE
This example config file shows the minimum contents for a system to run SELinux in enforcing mode, with a policy_name of 'targeted':
SELINUX = enforcing
SELINUXTYPE = targeted
