6 plymouthd_selinux - Security Enhanced Linux Policy for the plymouthd
7 processes
8
10 Security-Enhanced Linux secures the plymouthd processes via flexible
11 mandatory access control.
12
13 The plymouthd processes execute with the plymouthd_t SELinux type. You
14 can check if you have these processes running by executing the ps com‐
15 mand with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep plymouthd_t
20
21
22
24 The plymouthd_t SELinux type can be entered via the plymouthd_exec_t
25 file type.
26
27 The default entrypoint paths for the plymouthd_t domain are the follow‐
28 ing:
29
30 /sbin/plymouthd, /usr/sbin/plymouthd
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 plymouthd policy is very flexible allowing users to setup their ply‐
40 mouthd processes in as secure a method as possible.
41
42 The following process types are defined for plymouthd:
43
44 plymouth_t, plymouthd_t
45
46 Note: semanage permissive -a plymouthd_t can be used to make the
47 process type plymouthd_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. ply‐
54 mouthd policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run plymouthd with the tightest access
56 possible.
57
58
59
60 If you want to allow all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62
63 setsebool -P fips_mode 1
64
65
66
67 If you want to allow system to run with NIS, you must turn on the
68 nis_enabled boolean. Disabled by default.
69
70 setsebool -P nis_enabled 1
71
72
73
75 The SELinux process type plymouthd_t can manage files labeled with the
76 following file types. The paths listed are the default paths for these
77 file types. Note the processes UID still need to have DAC permissions.

152 SELinux requires files to have an extended attribute to define the file
153 type.
154
155 You can see the context of a file using the -Z option to ls
156
157 Policy governs the access confined processes have to these files.
158 SELinux plymouthd policy is very flexible allowing users to setup their
159 plymouthd processes in as secure a method as possible.
160
161 EQUIVALENCE DIRECTORIES
162
163
164 plymouthd policy stores data with multiple different file context types
165 under the /var/spool/plymouth directory. If you would like to store
166 the data in a different directory you can use the semanage command to
167 create an equivalence mapping. If you wanted to store this data under
168 the /srv directory you would execute the following command:
169
170 semanage fcontext -a -e /var/spool/plymouth /srv/plymouth
171 restorecon -R -v /srv/plymouth
172
173 STANDARD FILE CONTEXT
174
175 SELinux defines the file context types for the plymouthd, if you wanted
176 to store files with these types in a diffent paths, you need to execute
177 the semanage command to specify alternate labeling and then use re‐
178 storecon to put the labels on disk.
179
180 semanage fcontext -a -t plymouthd_var_run_t '/srv/myplymouthd_con‐
181 tent(/.*)?'
182 restorecon -R -v /srv/myplymouthd_content
183
184 Note: SELinux often uses regular expressions to specify labels that
185 match multiple files.
186
187 The following file types are defined for plymouthd:
188
189
190
191 plymouthd_exec_t
192
193 - Set files with the plymouthd_exec_t type, if you want to transition
194 an executable to the plymouthd_t domain.
195
196
197 Paths:
198 /sbin/plymouthd, /usr/sbin/plymouthd
199
200
201 plymouthd_spool_t
202
203 - Set files with the plymouthd_spool_t type, if you want to store the
204 plymouthd files under the /var/spool directory.
205
206
207
208 plymouthd_var_lib_t
209
210 - Set files with the plymouthd_var_lib_t type, if you want to store the
211 plymouthd files under the /var/lib directory.
212
213
214
215 plymouthd_var_log_t
216
217 - Set files with the plymouthd_var_log_t type, if you want to treat the
218 data as plymouthd var log data, usually stored under the /var/log di‐
219 rectory.
220
221
222 Paths:
223 /var/log/boot.log.*, /var/spool/plymouth/boot.log.*
224
225
226 plymouthd_var_run_t
227
228 - Set files with the plymouthd_var_run_t type, if you want to store the
229 plymouthd files under the /run or /var/run directory.
230
231
232
233 Note: File context can be temporarily modified with the chcon command.
234 If you want to permanently change the file context you need to use the
235 semanage fcontext command. This will modify the SELinux labeling data‐
236 base. You will need to use restorecon to apply the labels.
237
238
240 semanage fcontext can also be used to manipulate default file context
241 mappings.
242
243 semanage permissive can also be used to manipulate whether or not a
244 process type is permissive.
245
246 semanage module can also be used to enable/disable/install/remove pol‐
247 icy modules.
248
249 semanage boolean can also be used to manipulate the booleans
250
251
252 system-config-selinux is a GUI tool available to customize SELinux pol‐
253 icy settings.
