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 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
64 setsebool -P authlogin_nsswitch_use_ldap 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 confined applications to run with kerberos, you
76 must turn on the kerberos_enabled boolean. Enabled by default.
77
78 setsebool -P kerberos_enabled 1
79
80
81
82 If you want to allow system to run with NIS, you must turn on the
83 nis_enabled boolean. Disabled by default.
84
85 setsebool -P nis_enabled 1
86
87
88
89 If you want to allow confined applications to use nscd shared memory,
90 you must turn on the nscd_use_shm boolean. Disabled by default.
91
92 setsebool -P nscd_use_shm 1
93
94
95
97 The SELinux process type plymouthd_t can manage files labeled with the
98 following file types. The paths listed are the default paths for these
99 file types. Note the processes UID still need to have DAC permissions.

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