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 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 For example:
18 ps -eZ | grep pulseaudio_t
20
24 The pulseaudio_t SELinux type can be entered via the pulseaudio_exec_t
25 file type.
26 The default entrypoint paths for the pulseaudio_t domain are the fol‐
28 lowing:
29 /usr/bin/pulseaudio
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 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 The following process types are defined for pulseaudio:
43 pulseaudio_t
45 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
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 If you want to allow users to resolve user passwd entries directly from
61 ldap rather then using a sssd server, you must turn on the authlo‐
62 gin_nsswitch_use_ldap boolean. Disabled by default.
63 setsebool -P authlogin_nsswitch_use_ldap 1
65 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 setsebool -P fips_mode 1
72 If you want to allow confined applications to run with kerberos, you
76 must turn on the kerberos_enabled boolean. Enabled by default.
77 setsebool -P kerberos_enabled 1
79 If you want to allow system to run with NIS, you must turn on the
83 nis_enabled boolean. Disabled by default.
84 setsebool -P nis_enabled 1
86 If you want to allow confined applications to use nscd shared memory,
90 you must turn on the nscd_use_shm boolean. Enabled by default.
91 setsebool -P nscd_use_shm 1
93 If you want to allow regular users direct dri device access, you must
97 turn on the selinuxuser_direct_dri_enabled boolean. Enabled by default.
98 setsebool -P selinuxuser_direct_dri_enabled 1
100 If you want to support NFS home directories, you must turn on the
104 use_nfs_home_dirs boolean. Disabled by default.
105 setsebool -P use_nfs_home_dirs 1
107 If you want to support SAMBA home directories, you must turn on the
111 use_samba_home_dirs boolean. Disabled by default.
112 setsebool -P use_samba_home_dirs 1
114 If you want to allows clients to write to the X server shared memory
118 segments, you must turn on the xserver_clients_write_xshm boolean. Dis‐
119 abled by default.
120 setsebool -P xserver_clients_write_xshm 1
122
126 SELinux defines port types to represent TCP and UDP ports.
127 You can see the types associated with a port by using the following
129 command:
130 semanage port -l
132 Policy governs the access confined processes have to these ports.
135 SELinux pulseaudio policy is very flexible allowing users to setup
136 their pulseaudio processes in as secure a method as possible.
137 The following port types are defined for pulseaudio:
139 pulseaudio_port_t
142 Default Defined Ports:
146 tcp 4713
147 udp 4713
148
150 The SELinux process type pulseaudio_t can manage files labeled with the
151 following file types. The paths listed are the default paths for these
152 file types. Note the processes UID still need to have DAC permissions.

230 SELinux requires files to have an extended attribute to define the file
231 type.
232 You can see the context of a file using the -Z option to ls
234 Policy governs the access confined processes have to these files.
236 SELinux pulseaudio policy is very flexible allowing users to setup
237 their pulseaudio processes in as secure a method as possible.
238 STANDARD FILE CONTEXT
240 SELinux defines the file context types for the pulseaudio, if you
242 wanted to store files with these types in a diffent paths, you need to
243 execute the semanage command to sepecify alternate labeling and then
244 use restorecon to put the labels on disk.
245 semanage fcontext -a -t pulseaudio_var_run_t '/srv/mypulseaudio_con‐
247 tent(/.*)?'
248 restorecon -R -v /srv/mypulseaudio_content
249 Note: SELinux often uses regular expressions to specify labels that
251 match multiple files.
252 The following file types are defined for pulseaudio:
254 pulseaudio_exec_t
258 - Set files with the pulseaudio_exec_t type, if you want to transition
260 an executable to the pulseaudio_t domain.
261 pulseaudio_home_t
265 - Set files with the pulseaudio_home_t type, if you want to store
267 pulseaudio files in the users home directory.
268 Paths:
271 /root/.pulse(/.*)?, /root/.config/pulse(/.*)?, /root/.esd_auth,
272 /root/.pulse-cookie, /home/[^/]+/.pulse(/.*)?, /home/[^/]+/.con‐
273 fig/pulse(/.*)?, /home/[^/]+/.esd_auth, /home/[^/]+/.pulse-cookie
274 pulseaudio_tmpfs_t
277 - Set files with the pulseaudio_tmpfs_t type, if you want to store
279 pulseaudio files on a tmpfs file system.
280 pulseaudio_var_lib_t
284 - Set files with the pulseaudio_var_lib_t type, if you want to store
286 the pulseaudio files under the /var/lib directory.
287 pulseaudio_var_run_t
291 - Set files with the pulseaudio_var_run_t type, if you want to store
293 the pulseaudio files under the /run or /var/run directory.
294 Note: File context can be temporarily modified with the chcon command.
298 If you want to permanently change the file context you need to use the
299 semanage fcontext command. This will modify the SELinux labeling data‐
300 base. You will need to use restorecon to apply the labels.
301
304 semanage fcontext can also be used to manipulate default file context
305 mappings.
306 semanage permissive can also be used to manipulate whether or not a
308 process type is permissive.
309 semanage module can also be used to enable/disable/install/remove pol‐
311 icy modules.
312 semanage port can also be used to manipulate the port definitions
314 semanage boolean can also be used to manipulate the booleans
316 system-config-selinux is a GUI tool available to customize SELinux pol‐
319 icy settings.
