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 Enabled 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 regular users direct dri device access, you must
76 turn on the selinuxuser_direct_dri_enabled boolean. Enabled by default.
77
78 setsebool -P selinuxuser_direct_dri_enabled 1
79
80
81
82 If you want to support NFS home directories, you must turn on the
83 use_nfs_home_dirs boolean. Disabled by default.
84
85 setsebool -P use_nfs_home_dirs 1
86
87
88
89 If you want to support SAMBA home directories, you must turn on the
90 use_samba_home_dirs boolean. Disabled by default.
91
92 setsebool -P use_samba_home_dirs 1
93
94
95
96 If you want to allows clients to write to the X server shared memory
97 segments, you must turn on the xserver_clients_write_xshm boolean. Dis‐
98 abled by default.
99
100 setsebool -P xserver_clients_write_xshm 1
101
102
103
105 SELinux defines port types to represent TCP and UDP ports.
106
107 You can see the types associated with a port by using the following
108 command:
109
110 semanage port -l
111
112
113 Policy governs the access confined processes have to these ports.
114 SELinux pulseaudio policy is very flexible allowing users to setup
115 their pulseaudio processes in as secure a method as possible.
116
117 The following port types are defined for pulseaudio:
118
119
120 pulseaudio_port_t
121
122
123
124 Default Defined Ports:
125 tcp 4713
126 udp 4713
127
129 The SELinux process type pulseaudio_t can manage files labeled with the
130 following file types. The paths listed are the default paths for these
131 file types. Note the processes UID still need to have DAC permissions.
132
133 cifs_t
134
135
136 krb5_host_rcache_t
137
138 /var/tmp/krb5_0.rcache2

140 /var/tmp/nfs_0
141 /var/tmp/DNS_25

151
152 /var/lib/pulse(/.*)?
153
154 pulseaudio_var_run_t
155
156 /var/run/pulse(/.*)?
157
158 user_tmp_type
159
160 all user tmp files
161
162 virt_tmpfs_type
163
164
165
167 SELinux requires files to have an extended attribute to define the file
168 type.
169
170 You can see the context of a file using the -Z option to ls
171
172 Policy governs the access confined processes have to these files.
173 SELinux pulseaudio policy is very flexible allowing users to setup
174 their pulseaudio processes in as secure a method as possible.
175
176 STANDARD FILE CONTEXT
177
178 SELinux defines the file context types for the pulseaudio, if you
179 wanted to store files with these types in a diffent paths, you need to
180 execute the semanage command to specify alternate labeling and then use
181 restorecon to put the labels on disk.
182
183 semanage fcontext -a -t pulseaudio_var_run_t '/srv/mypulseaudio_con‐
184 tent(/.*)?'
185 restorecon -R -v /srv/mypulseaudio_content
186
187 Note: SELinux often uses regular expressions to specify labels that
188 match multiple files.
189
190 The following file types are defined for pulseaudio:
191
192
193
194 pulseaudio_exec_t
195
196 - Set files with the pulseaudio_exec_t type, if you want to transition
197 an executable to the pulseaudio_t domain.
198
199
200
201 pulseaudio_home_t
202
203 - Set files with the pulseaudio_home_t type, if you want to store
204 pulseaudio files in the users home directory.
205
206
207 Paths:
208 /root/.pulse(/.*)?, /root/.config/pulse(/.*)?, /root/.esd_auth,
209 /root/.pulse-cookie, /home/[^/]+/.pulse(/.*)?, /home/[^/]+/.con‐
210 fig/pulse(/.*)?, /home/[^/]+/.esd_auth, /home/[^/]+/.pulse-cookie
211
212
213 pulseaudio_tmpfs_t
214
215 - Set files with the pulseaudio_tmpfs_t type, if you want to store
216 pulseaudio files on a tmpfs file system.
217
218
219
220 pulseaudio_var_lib_t
221
222 - Set files with the pulseaudio_var_lib_t type, if you want to store
223 the pulseaudio files under the /var/lib directory.
224
225
226
227 pulseaudio_var_run_t
228
229 - Set files with the pulseaudio_var_run_t type, if you want to store
230 the pulseaudio files under the /run or /var/run directory.
231
232
233
234 Note: File context can be temporarily modified with the chcon command.
235 If you want to permanently change the file context you need to use the
236 semanage fcontext command. This will modify the SELinux labeling data‐
237 base. You will need to use restorecon to apply the labels.
238
239
241 semanage fcontext can also be used to manipulate default file context
242 mappings.
243
244 semanage permissive can also be used to manipulate whether or not a
245 process type is permissive.
246
247 semanage module can also be used to enable/disable/install/remove pol‐
248 icy modules.
249
250 semanage port can also be used to manipulate the port definitions
251
252 semanage boolean can also be used to manipulate the booleans
253
254
255 system-config-selinux is a GUI tool available to customize SELinux pol‐
256 icy settings.
