NAME

6       plymouth_selinux - Security Enhanced Linux Policy for the plymouth pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux secures the  plymouth  processes  via  flexible
11       mandatory access control.
12
13       The  plymouth  processes  execute with the plymouth_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 plymouth_t
20
21
22

ENTRYPOINTS

24       The plymouth_t SELinux type can be entered via the plymouth_exec_t file
25       type.
26
27       The default entrypoint paths for the plymouth_t domain are the  follow‐
28       ing:
29
30       /bin/plymouth
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       plymouth policy is very flexible allowing users to setup their plymouth
40       processes in as secure a method as possible.
41
42       The following process types are defined for plymouth:
43
44       plymouth_t, plymouthd_t
45
46       Note: semanage permissive -a plymouth_t can be used to make the process
47       type  plymouth_t permissive. SELinux does not deny access to permissive
48       process types, but the AVC (SELinux denials) messages are still  gener‐
49       ated.
50
51

BOOLEANS

53       SELinux  policy  is  customizable based on least access required.  ply‐
54       mouth policy is extremely flexible and has several booleans that  allow
55       you  to manipulate the policy and run plymouth with the tightest access
56       possible.
57
58
59
60       If you want to allow all domains to use other domains file descriptors,
61       you must turn on the allow_domain_fd_use boolean. Enabled by default.
62
63       setsebool -P allow_domain_fd_use 1
64
65
66
67       If  you want to allow sysadm to debug or ptrace all processes, you must
68       turn on the allow_ptrace boolean. Disabled by default.
69
70       setsebool -P allow_ptrace 1
71
72
73
74       If you want to allow all domains to have the kernel load  modules,  you
75       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
76       default.
77
78       setsebool -P domain_kernel_load_modules 1
79
80
81
82       If you want to allow all domains to execute in fips_mode, you must turn
83       on the fips_mode boolean. Enabled by default.
84
85       setsebool -P fips_mode 1
86
87
88
89       If you want to enable reading of urandom for all domains, you must turn
90       on the global_ssp boolean. Disabled by default.
91
92       setsebool -P global_ssp 1
93

MANAGED FILES

97       The SELinux process type plymouth_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.
100
101       initrc_tmp_t
102
103
104       mnt_t
105
106            /mnt(/[^/]*)
107            /mnt(/[^/]*)?
108            /rhev(/[^/]*)?
109            /media(/[^/]*)
110            /media(/[^/]*)?
111            /etc/rhgb(/.*)?
112            /media/.hal-.*
113            /net
114            /afs
115            /rhev
116            /misc
117
118       tmp_t
119
120            /tmp
121            /usr/tmp
122            /var/tmp
123            /tmp-inst
124            /var/tmp-inst
125            /var/tmp/vi.recover

FILE CONTEXTS

129       SELinux requires files to have an extended attribute to define the file
130       type.
131
132       You can see the context of a file using the -Z option to ls
133
134       Policy  governs  the  access  confined  processes  have to these files.
135       SELinux plymouth policy is very flexible allowing users to setup  their
136       plymouth processes in as secure a method as possible.
137
138       STANDARD FILE CONTEXT
139
140       SELinux  defines the file context types for the plymouth, if you wanted
141       to store files with these types in a diffent paths, you need to execute
142       the  semanage  command  to  sepecify  alternate  labeling  and then use
143       restorecon to put the labels on disk.
144
145       semanage  fcontext  -a  -t  plymouthd_var_run_t   '/srv/myplymouth_con‐
146       tent(/.*)?'
147       restorecon -R -v /srv/myplymouth_content
148
149       Note:  SELinux  often  uses  regular expressions to specify labels that
150       match multiple files.
151
152       The following file types are defined for plymouth:
153
154
155
156       plymouth_exec_t
157
158       - Set files with the plymouth_exec_t type, if you want to transition an
159       executable to the plymouth_t domain.
160
161
162
163       plymouthd_exec_t
164
165       -  Set  files with the plymouthd_exec_t type, if you want to transition
166       an executable to the plymouthd_t domain.
167
168
169
170       plymouthd_spool_t
171
172       - Set files with the plymouthd_spool_t type, if you want to  store  the
173       plymouthd files under the /var/spool directory.
174
175
176
177       plymouthd_var_lib_t
178
179       - Set files with the plymouthd_var_lib_t type, if you want to store the
180       plymouthd files under the /var/lib directory.
181
182
183
184       plymouthd_var_run_t
185
186       - Set files with the plymouthd_var_run_t type, if you want to store the
187       plymouthd files under the /run or /var/run directory.
188
189
190
191       Note:  File context can be temporarily modified with the chcon command.
192       If you want to permanently change the file context you need to use  the
193       semanage fcontext command.  This will modify the SELinux labeling data‐
194       base.  You will need to use restorecon to apply the labels.
195
196

COMMANDS

198       semanage fcontext can also be used to manipulate default  file  context
199       mappings.
200
201       semanage  permissive  can  also  be used to manipulate whether or not a
202       process type is permissive.
203
204       semanage module can also be used to enable/disable/install/remove  pol‐
205       icy modules.
206
207       semanage boolean can also be used to manipulate the booleans
208
209
210       system-config-selinux is a GUI tool available to customize SELinux pol‐
211       icy settings.
