6 soundd_selinux - Security Enhanced Linux Policy for the soundd pro‐
7 cesses
8
10 Security-Enhanced Linux secures the soundd processes via flexible
11 mandatory access control.
12 The soundd processes execute with the soundd_t SELinux type. You can
14 check if you have these processes running by executing the ps command
15 with the -Z qualifier.
16 For example:
18 ps -eZ | grep soundd_t
20
24 The soundd_t SELinux type can be entered via the soundd_exec_t file
25 type.
26 The default entrypoint paths for the soundd_t domain are the following:
28 /usr/bin/nasd, /usr/sbin/yiff, /usr/bin/gpe-soundserver
30
32 SELinux defines process types (domains) for each process running on the
33 system
34 You can see the context of a process using the -Z option to ps
36 Policy governs the access confined processes have to files. SELinux
38 soundd policy is very flexible allowing users to setup their soundd
39 processes in as secure a method as possible.
40 The following process types are defined for soundd:
42 soundd_t
44 Note: semanage permissive -a soundd_t can be used to make the process
46 type soundd_t permissive. SELinux does not deny access to permissive
47 process types, but the AVC (SELinux denials) messages are still gener‐
48 ated.
49
52 SELinux policy is customizable based on least access required. soundd
53 policy is extremely flexible and has several booleans that allow you to
54 manipulate the policy and run soundd with the tightest access possible.
55 If you want to allow all daemons to write corefiles to /, you must turn
59 on the daemons_dump_core boolean. Disabled by default.
60 setsebool -P daemons_dump_core 1
62 If you want to enable cluster mode for daemons, you must turn on the
66 daemons_enable_cluster_mode boolean. Enabled by default.
67 setsebool -P daemons_enable_cluster_mode 1

118 must turn on the domain_kernel_load_modules boolean. Disabled by
119 default.
120 setsebool -P domain_kernel_load_modules 1
122 If you want to allow all domains to execute in fips_mode, you must turn

140 SELinux defines port types to represent TCP and UDP ports.
141 You can see the types associated with a port by using the following
143 command:
144 semanage port -l
146 Policy governs the access confined processes have to these ports.
149 SELinux soundd policy is very flexible allowing users to setup their
150 soundd processes in as secure a method as possible.
151 The following port types are defined for soundd:
153 soundd_port_t
156 Default Defined Ports:
160 tcp 8000,9433,16001
161
163 The SELinux process type soundd_t can manage files labeled with the
164 following file types. The paths listed are the default paths for these
165 file types. Note the processes UID still need to have DAC permissions.
166 cluster_conf_t
168 /etc/cluster(/.*)?

219 SELinux requires files to have an extended attribute to define the file
220 type.
221 You can see the context of a file using the -Z option to ls
223 Policy governs the access confined processes have to these files.
225 SELinux soundd policy is very flexible allowing users to setup their
226 soundd processes in as secure a method as possible.
227 STANDARD FILE CONTEXT
229 SELinux defines the file context types for the soundd, if you wanted to
231 store files with these types in a diffent paths, you need to execute
232 the semanage command to sepecify alternate labeling and then use
233 restorecon to put the labels on disk.
234 semanage fcontext -a -t soundd_var_run_t '/srv/mysoundd_content(/.*)?'
236 restorecon -R -v /srv/mysoundd_content
237 Note: SELinux often uses regular expressions to specify labels that
239 match multiple files.
240 The following file types are defined for soundd:
242 soundd_etc_t
246 - Set files with the soundd_etc_t type, if you want to store soundd
248 files in the /etc directories.
249 Paths:
252 /etc/nas(/.*)?, /etc/yiff(/.*)?
253 soundd_exec_t
256 - Set files with the soundd_exec_t type, if you want to transition an
258 executable to the soundd_t domain.
259 Paths:
262 /usr/bin/nasd, /usr/sbin/yiff, /usr/bin/gpe-soundserver
263 soundd_initrc_exec_t
266 - Set files with the soundd_initrc_exec_t type, if you want to transi‐
268 tion an executable to the soundd_initrc_t domain.
269 soundd_state_t
273 - Set files with the soundd_state_t type, if you want to treat the
275 files as soundd state data.
276 soundd_tmp_t
280 - Set files with the soundd_tmp_t type, if you want to store soundd
282 temporary files in the /tmp directories.
283 soundd_tmpfs_t
287 - Set files with the soundd_tmpfs_t type, if you want to store soundd
289 files on a tmpfs file system.
290 soundd_var_run_t
294 - Set files with the soundd_var_run_t type, if you want to store the
296 soundd files under the /run or /var/run directory.
297 Paths:
300 /var/run/nasd(/.*)?, /var/run/yiff-[0-9]+.pid
301 Note: File context can be temporarily modified with the chcon command.
304 If you want to permanently change the file context you need to use the
305 semanage fcontext command. This will modify the SELinux labeling data‐
306 base. You will need to use restorecon to apply the labels.
307
310 semanage fcontext can also be used to manipulate default file context
311 mappings.
312 semanage permissive can also be used to manipulate whether or not a
314 process type is permissive.
315 semanage module can also be used to enable/disable/install/remove pol‐
317 icy modules.
318 semanage port can also be used to manipulate the port definitions
320 semanage boolean can also be used to manipulate the booleans
322 system-config-selinux is a GUI tool available to customize SELinux pol‐
325 icy settings.
