.SH "NAME"
xonotic_selinux \- Security Enhanced Linux Policy for the xonotic processes
.SH "DESCRIPTION"

Security-Enhanced Linux secures the xonotic processes via flexible mandatory access control.

The xonotic processes execute with the xonotic_t SELinux type. You can check if you have these processes running by executing the \fBps\fP command with the \fB\-Z\fP qualifier.

For example:

.B ps -eZ | grep xonotic_t


.SH "ENTRYPOINTS"

The xonotic_t SELinux type can be entered via the \fBxonotic_exec_t\fP file type.

The default entrypoint paths for the xonotic_t domain are the following:

/opt/xonotic/engine/.*
.SH PROCESS TYPES
SELinux defines process types (domains) for each process running on the system
.PP
You can see the context of a process using the \fB\-Z\fP option to \fBps\bP
.PP
Policy governs the access confined processes have to files.
SELinux xonotic policy is very flexible allowing users to setup their xonotic processes in as secure a method as possible.
.PP
The following process types are defined for xonotic:

.EX
.B xonotic_t
.EE
.PP
Note:
.B semanage permissive -a xonotic_t
can be used to make the process type xonotic_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.

.SH BOOLEANS
SELinux policy is customizable based on least access required.  xonotic policy is extremely flexible and has several booleans that allow you to manipulate the policy and run xonotic with the tightest access possible.


.PP
If you want to dontaudit all daemons scheduling requests (setsched, sys_nice), you must turn on the daemons_dontaudit_scheduling boolean. Enabled by default.

.EX
.B setsebool -P daemons_dontaudit_scheduling 1

.EE

.PP
If you want to allow all domains to execute in fips_mode, you must turn on the fips_mode boolean. Enabled by default.

.EX
.B setsebool -P fips_mode 1

.EE

.PP
If you want to allow confined applications to use nscd shared memory, you must turn on the nscd_use_shm boolean. Enabled by default.

.EX
.B setsebool -P nscd_use_shm 1

.EE

.SH PORT TYPES
SELinux defines port types to represent TCP and UDP ports.
.PP
You can see the types associated with a port by using the following command:

.B semanage port -l

.PP
Policy governs the access confined processes have to these ports.
SELinux xonotic policy is very flexible allowing users to setup their xonotic processes in as secure a method as possible.
.PP
The following port types are defined for xonotic:

.EX
.TP 5
.B xonotic_port_t
.TP 10
.EE

.SH "MANAGED FILES"

The SELinux process type xonotic_t can manage files labeled with the following file types.  The paths listed are the default paths for these file types.  Note the processes UID still need to have DAC permissions.

.SH FILE CONTEXTS
SELinux requires files to have an extended attribute to define the file type.
.PP
You can see the context of a file using the \fB\-Z\fP option to \fBls\bP
.PP
Policy governs the access confined processes have to these files.
SELinux xonotic policy is very flexible allowing users to setup their xonotic processes in as secure a method as possible.
.PP

.PP
.B STANDARD FILE CONTEXT

SELinux defines the file context types for the xonotic, if you wanted to
store files with these types in a different paths, you need to execute the semanage command to specify alternate labeling and then use restorecon to put the labels on disk.

.B semanage fcontext -a -t xonotic_exec_t '/srv/xonotic/content(/.*)?'
.br
.B restorecon -R -v /srv/myxonotic_content

Note: SELinux often uses regular expressions to specify labels that match multiple files.

.I The following file types are defined for xonotic:


.EX
.PP
.B xonotic_exec_t
.EE

- Set files with the xonotic_exec_t type, if you want to transition an executable to the xonotic_t domain.


.EX
.PP
.B xonotic_file_t
.EE

- Set files with the xonotic_file_t type, if you want to treat the files as xonotic content.

.br
.TP 5
Paths:
/opt/xonotic/.*, /opt/xonotic

.EX
.PP
.B xonotic_runtime_t
.EE

- Set files with the xonotic_runtime_t type, if you want to treat the files as xonotic runtime data.

.br
.TP 5
Paths:
/run/xonotic/.*, /var/run/xonotic/.*, /opt/xonotic/server/.*, /run/xonotic, /var/run/xonotic, /opt/xonotic/server, /mnt/demos/.*, /mnt/demos

.PP
Note: File context can be temporarily modified with the chcon command.  If you want to permanently change the file context you need to use the
.B semanage fcontext
command.  This will modify the SELinux labeling database.  You will need to use
.B restorecon
to apply the labels.

.SH "COMMANDS"
.B semanage fcontext
can also be used to manipulate default file context mappings.
.PP
.B semanage permissive
can also be used to manipulate whether or not a process type is permissive.
.PP
.B semanage module
can also be used to enable/disable/install/remove policy modules.

.B semanage port
can also be used to manipulate the port definitions

.B semanage boolean
can also be used to manipulate the booleans

.PP
.B system-config-selinux
is a GUI tool available to customize SELinux policy settings.
