6 pulseaudio_selinux - Security Enhanced Linux Policy for the pulseaudio
7 processes
8
10 Security-Enhanced Linux secures the pulseaudio processes via flexible
11 mandatory access control.
12
13 The pulseaudio processes execute with the pulseaudio_t SELinux type.
14 You can check if you have these processes running by executing the ps
15 command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep pulseaudio_t
20
21
22
24 The pulseaudio_t SELinux type can be entered via the pulseaudio_exec_t
25 file type.
26
27 The default entrypoint paths for the pulseaudio_t domain are the fol‐
28 lowing:
29
30 /usr/bin/pulseaudio
31
33 SELinux defines process types (domains) for each process running on the
34 system
35
36 You can see the context of a process using the -Z option to ps
37
38 Policy governs the access confined processes have to files. SELinux
39 pulseaudio policy is very flexible allowing users to setup their
40 pulseaudio processes in as secure a method as possible.
41
42 The following process types are defined for pulseaudio:
43
44 pulseaudio_t
45
46 Note: semanage permissive -a pulseaudio_t can be used to make the
47 process type pulseaudio_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
51
53 SELinux policy is customizable based on least access required.
54 pulseaudio policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run pulseaudio with the tightest
56 access possible.
57
58
59
60 If you want to deny all system processes and Linux users to use blue‐
61 tooth wireless technology, you must turn on the deny_bluetooth boolean.
62 Disabled by default.
63
64 setsebool -P deny_bluetooth 1
65
66
67
68 If you want to allow all domains to execute in fips_mode, you must turn
69 on the fips_mode boolean. Enabled by default.
70
71 setsebool -P fips_mode 1
72
73
74
75 If you want to allow system to run with NIS, you must turn on the
76 nis_enabled boolean. Disabled by default.
77
78 setsebool -P nis_enabled 1
79
80
81
82 If you want to allow regular users direct dri device access, you must
83 turn on the selinuxuser_direct_dri_enabled boolean. Enabled by default.
84
85 setsebool -P selinuxuser_direct_dri_enabled 1
86
87
88
89 If you want to support NFS home directories, you must turn on the
90 use_nfs_home_dirs boolean. Disabled by default.
91
92 setsebool -P use_nfs_home_dirs 1
93
94
95
96 If you want to support SAMBA home directories, you must turn on the
97 use_samba_home_dirs boolean. Disabled by default.
98
99 setsebool -P use_samba_home_dirs 1
100
101
102
103 If you want to allows clients to write to the X server shared memory
104 segments, you must turn on the xserver_clients_write_xshm boolean. Dis‐
105 abled by default.
106
107 setsebool -P xserver_clients_write_xshm 1
108
109
110
112 SELinux defines port types to represent TCP and UDP ports.
113
114 You can see the types associated with a port by using the following
115 command:
116
117 semanage port -l
118
119
120 Policy governs the access confined processes have to these ports.
121 SELinux pulseaudio policy is very flexible allowing users to setup
122 their pulseaudio processes in as secure a method as possible.
123
124 The following port types are defined for pulseaudio:
125
126
127 pulseaudio_port_t
128
129
130
131 Default Defined Ports:
132 tcp 4713
133 udp 4713
134
136 The SELinux process type pulseaudio_t can manage files labeled with the
137 following file types. The paths listed are the default paths for these
138 file types. Note the processes UID still need to have DAC permissions.
139

160
161 pulseaudio_var_run_t
162
163 /var/run/pulse(/.*)?

165 user_tmp_type
166
167 all user tmp files
168
169 virt_tmpfs_type
170
171
172
174 SELinux requires files to have an extended attribute to define the file
175 type.
176
177 You can see the context of a file using the -Z option to ls
178
179 Policy governs the access confined processes have to these files.
180 SELinux pulseaudio policy is very flexible allowing users to setup
181 their pulseaudio processes in as secure a method as possible.
182
183 STANDARD FILE CONTEXT
184
185 SELinux defines the file context types for the pulseaudio, if you
186 wanted to store files with these types in a different paths, you need
187 to execute the semanage command to specify alternate labeling and then
188 use restorecon to put the labels on disk.
189
190 semanage fcontext -a -t pulseaudio_exec_t '/srv/pulseaudio/con‐
191 tent(/.*)?'
192 restorecon -R -v /srv/mypulseaudio_content
193
194 Note: SELinux often uses regular expressions to specify labels that
195 match multiple files.
196
197 The following file types are defined for pulseaudio:
198
199
200
201 pulseaudio_exec_t
202
203 - Set files with the pulseaudio_exec_t type, if you want to transition
204 an executable to the pulseaudio_t domain.
205
206
207
208 pulseaudio_home_t
209
210 - Set files with the pulseaudio_home_t type, if you want to store
211 pulseaudio files in the users home directory.
212
213
214 Paths:
215 /root/.pulse(/.*)?, /root/.config/pulse(/.*)?, /root/.esd_auth,
216 /root/.pulse-cookie, /home/[^/]+/.pulse(/.*)?, /home/[^/]+/.con‐
217 fig/pulse(/.*)?, /home/[^/]+/.esd_auth, /home/[^/]+/.pulse-cookie
218
219
220 pulseaudio_tmpfs_t
221
222 - Set files with the pulseaudio_tmpfs_t type, if you want to store
223 pulseaudio files on a tmpfs file system.
224
225
226
227 pulseaudio_var_lib_t
228
229 - Set files with the pulseaudio_var_lib_t type, if you want to store
230 the pulseaudio files under the /var/lib directory.
231
232
233
234 pulseaudio_var_run_t
235
236 - Set files with the pulseaudio_var_run_t type, if you want to store
237 the pulseaudio files under the /run or /var/run directory.
238
239
240
241 Note: File context can be temporarily modified with the chcon command.
242 If you want to permanently change the file context you need to use the
243 semanage fcontext command. This will modify the SELinux labeling data‐
244 base. You will need to use restorecon to apply the labels.
245
246
248 semanage fcontext can also be used to manipulate default file context
249 mappings.
250
251 semanage permissive can also be used to manipulate whether or not a
252 process type is permissive.
253
254 semanage module can also be used to enable/disable/install/remove pol‐
255 icy modules.
256
257 semanage port can also be used to manipulate the port definitions
258
259 semanage boolean can also be used to manipulate the booleans
260
261
262 system-config-selinux is a GUI tool available to customize SELinux pol‐
263 icy settings.
