6 mpd_selinux - Security Enhanced Linux Policy for the mpd processes
7
9 Security-Enhanced Linux secures the mpd processes via flexible manda‐
10 tory access control.
11 The mpd processes execute with the mpd_t SELinux type. You can check if
13 you have these processes running by executing the ps command with the
14 -Z qualifier.
15 For example:
17 ps -eZ | grep mpd_t
19
23 The mpd_t SELinux type can be entered via the mpd_exec_t file type.
24 The default entrypoint paths for the mpd_t domain are the following:
26 /usr/bin/mpd
28
30 SELinux defines process types (domains) for each process running on the
31 system
32 You can see the context of a process using the -Z option to ps
34 Policy governs the access confined processes have to files. SELinux
36 mpd policy is very flexible allowing users to setup their mpd processes
37 in as secure a method as possible.
38 The following process types are defined for mpd:
40 mpd_t
42 Note: semanage permissive -a mpd_t can be used to make the process type
44 mpd_t permissive. SELinux does not deny access to permissive process
45 types, but the AVC (SELinux denials) messages are still generated.
46
49 SELinux policy is customizable based on least access required. mpd
50 policy is extremely flexible and has several booleans that allow you to
51 manipulate the policy and run mpd with the tightest access possible.
52 If you want to determine whether mpd can traverse user home directo‐
56 ries, you must turn on the mpd_enable_homedirs boolean. Disabled by de‐
57 fault.
58 setsebool -P mpd_enable_homedirs 1
60 If you want to determine whether mpd can use cifs file systems, you
64 must turn on the mpd_use_cifs boolean. Disabled by default.
65 setsebool -P mpd_use_cifs 1
67 If you want to determine whether mpd can use nfs file systems, you must
71 turn on the mpd_use_nfs boolean. Disabled by default.
72 setsebool -P mpd_use_nfs 1
74 If you want to allow all domains to execute in fips_mode, you must turn
78 on the fips_mode boolean. Enabled by default.
79 setsebool -P fips_mode 1
81
85 SELinux defines port types to represent TCP and UDP ports.
86 You can see the types associated with a port by using the following
88 command:
89 semanage port -l
91 Policy governs the access confined processes have to these ports.
94 SELinux mpd policy is very flexible allowing users to setup their mpd
95 processes in as secure a method as possible.
96 The following port types are defined for mpd:
98 mpd_port_t
101 Default Defined Ports:
105 tcp 6600
106
108 The SELinux process type mpd_t can manage files labeled with the fol‐
109 lowing file types. The paths listed are the default paths for these
110 file types. Note the processes UID still need to have DAC permissions.

193 SELinux requires files to have an extended attribute to define the file
194 type.
195 You can see the context of a file using the -Z option to ls
197 Policy governs the access confined processes have to these files.
199 SELinux mpd policy is very flexible allowing users to setup their mpd
200 processes in as secure a method as possible.
201 EQUIVALENCE DIRECTORIES
203 mpd policy stores data with multiple different file context types under
206 the /var/lib/mpd directory. If you would like to store the data in a
207 different directory you can use the semanage command to create an
208 equivalence mapping. If you wanted to store this data under the /srv
209 directory you would execute the following command:
210 semanage fcontext -a -e /var/lib/mpd /srv/mpd
212 restorecon -R -v /srv/mpd
213 STANDARD FILE CONTEXT
215 SELinux defines the file context types for the mpd, if you wanted to
217 store files with these types in a diffent paths, you need to execute
218 the semanage command to specify alternate labeling and then use re‐
219 storecon to put the labels on disk.
220 semanage fcontext -a -t mpd_var_run_t '/srv/mympd_content(/.*)?'
222 restorecon -R -v /srv/mympd_content
223 Note: SELinux often uses regular expressions to specify labels that
225 match multiple files.
226 The following file types are defined for mpd:
228 mpd_data_t
232 - Set files with the mpd_data_t type, if you want to treat the files as
234 mpd content.
235 Paths:
238 /var/lib/mpd/music(/.*)?, /var/lib/mpd/playlists(/.*)?
239 mpd_etc_t
242 - Set files with the mpd_etc_t type, if you want to store mpd files in
244 the /etc directories.
245 mpd_exec_t
249 - Set files with the mpd_exec_t type, if you want to transition an exe‐
251 cutable to the mpd_t domain.
252 mpd_home_t
256 - Set files with the mpd_home_t type, if you want to store mpd files in
258 the users home directory.
259 mpd_initrc_exec_t
263 - Set files with the mpd_initrc_exec_t type, if you want to transition
265 an executable to the mpd_initrc_t domain.
266 mpd_log_t
270 - Set files with the mpd_log_t type, if you want to treat the data as
272 mpd log data, usually stored under the /var/log directory.
273 mpd_tmp_t
277 - Set files with the mpd_tmp_t type, if you want to store mpd temporary
279 files in the /tmp directories.
280 mpd_tmpfs_t
284 - Set files with the mpd_tmpfs_t type, if you want to store mpd files
286 on a tmpfs file system.
287 mpd_user_data_t
291 - Set files with the mpd_user_data_t type, if you want to treat the
293 files as mpd user content.
294 mpd_var_lib_t
298 - Set files with the mpd_var_lib_t type, if you want to store the mpd
300 files under the /var/lib directory.
301 mpd_var_run_t
305 - Set files with the mpd_var_run_t type, if you want to store the mpd
307 files under the /run or /var/run directory.
308 Note: File context can be temporarily modified with the chcon command.
312 If you want to permanently change the file context you need to use the
313 semanage fcontext command. This will modify the SELinux labeling data‐
314 base. You will need to use restorecon to apply the labels.
315
318 semanage fcontext can also be used to manipulate default file context
319 mappings.
320 semanage permissive can also be used to manipulate whether or not a
322 process type is permissive.
323 semanage module can also be used to enable/disable/install/remove pol‐
325 icy modules.
326 semanage port can also be used to manipulate the port definitions
328 semanage boolean can also be used to manipulate the booleans
330 system-config-selinux is a GUI tool available to customize SELinux pol‐
333 icy settings.
