NAME

6       plymouthd_selinux  -  Security  Enhanced Linux Policy for the plymouthd
7       processes
8

DESCRIPTION

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

ENTRYPOINTS

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

PROCESS TYPES

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

BOOLEANS

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

MANAGED FILES

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.

FILE CONTEXTS

137       SELinux requires files to have an extended attribute to define the file
138       type.
139
140       You can see the context of a file using the -Z option to ls
141
142       Policy  governs  the  access  confined  processes  have to these files.
143       SELinux plymouthd policy is very flexible allowing users to setup their
144       plymouthd processes in as secure a method as possible.
145
146       EQUIVALENCE DIRECTORIES
147
148
149       plymouthd policy stores data with multiple different file context types
150       under the /var/spool/plymouth directory.  If you would  like  to  store
151       the  data  in a different directory you can use the semanage command to
152       create an equivalence mapping.  If you wanted to store this data  under
153       the /srv directory you would execute the following command:
154
155       semanage fcontext -a -e /var/spool/plymouth /srv/plymouth
156       restorecon -R -v /srv/plymouth
157
158       STANDARD FILE CONTEXT
159
160       SELinux defines the file context types for the plymouthd, if you wanted
161       to store files with these types in a diffent paths, you need to execute
162       the  semanage  command  to  sepecify  alternate  labeling  and then use
163       restorecon to put the labels on disk.
164
165       semanage  fcontext  -a  -t  plymouthd_var_run_t  '/srv/myplymouthd_con‐
166       tent(/.*)?'
167       restorecon -R -v /srv/myplymouthd_content
168
169       Note:  SELinux  often  uses  regular expressions to specify labels that
170       match multiple files.
171
172       The following file types are defined for plymouthd:
173
174
175
176       plymouthd_exec_t
177
178       - Set files with the plymouthd_exec_t type, if you want  to  transition
179       an executable to the plymouthd_t domain.
180
181
182       Paths:
183            /sbin/plymouthd, /usr/sbin/plymouthd
184
185
186       plymouthd_spool_t
187
188       -  Set  files with the plymouthd_spool_t type, if you want to store the
189       plymouthd files under the /var/spool directory.
190
191
192
193       plymouthd_var_lib_t
194
195       - Set files with the plymouthd_var_lib_t type, if you want to store the
196       plymouthd files under the /var/lib directory.
197
198
199
200       plymouthd_var_log_t
201
202       - Set files with the plymouthd_var_log_t type, if you want to treat the
203       data as plymouthd var log  data,  usually  stored  under  the  /var/log
204       directory.
205
206
207       Paths:
208            /var/log/boot.log.*, /var/spool/plymouth/boot.log.*
209
210
211       plymouthd_var_run_t
212
213       - Set files with the plymouthd_var_run_t type, if you want to store the
214       plymouthd files under the /run or /var/run directory.
215
216
217
218       Note: File context can be temporarily modified with the chcon  command.
219       If  you want to permanently change the file context you need to use the
220       semanage fcontext command.  This will modify the SELinux labeling data‐
221       base.  You will need to use restorecon to apply the labels.
222
223

COMMANDS

225       semanage  fcontext  can also be used to manipulate default file context
226       mappings.
227
228       semanage permissive can also be used to manipulate  whether  or  not  a
229       process type is permissive.
230
231       semanage  module can also be used to enable/disable/install/remove pol‐
232       icy modules.
233
234       semanage boolean can also be used to manipulate the booleans
235
236
237       system-config-selinux is a GUI tool available to customize SELinux pol‐
238       icy settings.
