mpd_selinux(8) mpd SELinux Policy documentation mpd_selinux(8)NAMEmpd_selinux - Security Enhanced Linux Policy for the mpd processes
DESCRIPTION
Security-Enhanced Linux secures the mpd processes via flexible manda‐
tory access control.
BOOLEANS
SELinux policy is customizable based on least access required. mpd
policy is extremely flexible and has several booleans that allow you to
manipulate the policy and run mpd with the tightest access possible.
If you want to allow all daemons to write corefiles to , you must turn
on the allow_daemons_dump_core boolean.
setsebool -P allow_daemons_dump_core 1
If you want to allow Apache to execute tmp content, you must turn on
the httpd_tmp_exec boolean.
setsebool -P httpd_tmp_exec 1
If you want to allow mplayer executable stac, you must turn on the
allow_mplayer_execstack boolean.
setsebool -P allow_mplayer_execstack 1
If you want to allow video playing tools to run unconfine, you must
turn on the unconfined_mplayer boolean.
setsebool -P unconfined_mplayer 1
If you want to allow gssd to read temp directory. For access to ker‐
beros tgt, you must turn on the allow_gssd_read_tmp boolean.
setsebool -P allow_gssd_read_tmp 1
NSSWITCH DOMAIN
If you want to allow users to login using a sssd serve for the mpd_t,
mplayer_t, you must turn on the authlogin_nsswitch_use_ldap boolean.
setsebool -P authlogin_nsswitch_use_ldap 1
If you want to allow confined applications to run with kerberos for the
mpd_t, mplayer_t, you must turn on the allow_kerberos boolean.
setsebool -P allow_kerberos 1
If you want to allow system to run with NI for the mpd_t, mplayer_t,
you must turn on the allow_ypbind boolean.
setsebool -P allow_ypbind 1
FILE CONTEXTS
SELinux requires files to have an extended attribute to define the file
type.
You can see the context of a file using the -Z option to ls
Policy governs the access confined processes have to these files.
SELinux mpd policy is very flexible allowing users to setup their mpd
processes in as secure a method as possible.
The following file types are defined for mpd:
mpd_data_t
- Set files with the mpd_data_t type, if you want to treat the files as
mpd content.
Paths:
/var/lib/mpd/playlists(/.*)?, /var/lib/mpd/music(/.*)?
mpd_etc_t
- Set files with the mpd_etc_t type, if you want to store mpd files in
the /etc directories.
mpd_exec_t
- Set files with the mpd_exec_t type, if you want to transition an exe‐
cutable to the mpd_t domain.
mpd_initrc_exec_t
- Set files with the mpd_initrc_exec_t type, if you want to transition
an executable to the mpd_initrc_t domain.
mpd_log_t
- Set files with the mpd_log_t type, if you want to treat the data as
mpd log data, usually stored under the /var/log directory.
mpd_tmp_t
- Set files with the mpd_tmp_t type, if you want to store mpd temporary
files in the /tmp directories.
mpd_tmpfs_t
- Set files with the mpd_tmpfs_t type, if you want to store mpd files
on a tmpfs file system.
mpd_var_lib_t
- Set files with the mpd_var_lib_t type, if you want to store the mpd
files under the /var/lib directory.
Note: File context can be temporarily modified with the chcon command.
If you want to permanantly change the file context you need to use the
semanage fcontext command. This will modify the SELinux labeling data‐
base. You will need to use restorecon to apply the labels.
PORT TYPES
SELinux defines port types to represent TCP and UDP ports.
You can see the types associated with a port by using the following
command:
semanage port -l
Policy governs the access confined processes have to these ports.
SELinux mpd policy is very flexible allowing users to setup their mpd
processes in as secure a method as possible.
The following port types are defined for mpd:
mpd_port_t
Default Defined Ports:
tcp 6600
PROCESS TYPES
SELinux defines process types (domains) for each process running on the
system
You can see the context of a process using the -Z option to ps
Policy governs the access confined processes have to files. SELinux
mpd policy is very flexible allowing users to setup their mpd processes
in as secure a method as possible.
The following process types are defined for mpd:
mpd_t, mplayer_t
Note: semanage permissive -a PROCESS_TYPE can be used to make a process
type permissive. Permissive process types are not denied access by
SELinux. AVC messages will still be generated.
COMMANDS
semanage fcontext can also be used to manipulate default file context
mappings.
semanage permissive can also be used to manipulate whether or not a
process type is permissive.
semanage module can also be used to enable/disable/install/remove pol‐
icy modules.
semanage port can also be used to manipulate the port definitions
semanage boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux pol‐
icy settings.
