6 plymouth_selinux - Security Enhanced Linux Policy for the plymouth pro‐
7 cesses
8
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
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, /usr/bin/plymouth
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 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
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 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
68 SELinux requires files to have an extended attribute to define the file
69 type.
70
71 You can see the context of a file using the -Z option to ls
72
73 Policy governs the access confined processes have to these files.
74 SELinux plymouth policy is very flexible allowing users to setup their
75 plymouth processes in as secure a method as possible.
76
77 STANDARD FILE CONTEXT
78
79 SELinux defines the file context types for the plymouth, if you wanted
80 to store files with these types in a diffent paths, you need to execute
81 the semanage command to sepecify alternate labeling and then use
82 restorecon to put the labels on disk.
83
84 semanage fcontext -a -t plymouthd_var_run_t '/srv/myplymouth_con‐
85 tent(/.*)?'
86 restorecon -R -v /srv/myplymouth_content
87
88 Note: SELinux often uses regular expressions to specify labels that
89 match multiple files.
90
91 The following file types are defined for plymouth:
92
93
94
95 plymouth_exec_t
96
97 - Set files with the plymouth_exec_t type, if you want to transition an
98 executable to the plymouth_t domain.
99
100
101 Paths:
102 /bin/plymouth, /usr/bin/plymouth
103
104
105 plymouthd_exec_t
106
107 - Set files with the plymouthd_exec_t type, if you want to transition
108 an executable to the plymouthd_t domain.
109
110
111 Paths:
112 /sbin/plymouthd, /usr/sbin/plymouthd
113
114
115 plymouthd_spool_t
116
117 - Set files with the plymouthd_spool_t type, if you want to store the
118 plymouthd files under the /var/spool directory.
119
120
121
122 plymouthd_var_lib_t
123
124 - Set files with the plymouthd_var_lib_t type, if you want to store the
125 plymouthd files under the /var/lib directory.
126
127
128
129 plymouthd_var_log_t
130
131 - Set files with the plymouthd_var_log_t type, if you want to treat the
132 data as plymouthd var log data, usually stored under the /var/log
133 directory.
134
135
136
137 plymouthd_var_run_t
138
139 - Set files with the plymouthd_var_run_t type, if you want to store the
140 plymouthd files under the /run or /var/run directory.
141
142
143
144 Note: File context can be temporarily modified with the chcon command.
145 If you want to permanently change the file context you need to use the
146 semanage fcontext command. This will modify the SELinux labeling data‐
147 base. You will need to use restorecon to apply the labels.
148
149
151 semanage fcontext can also be used to manipulate default file context
152 mappings.
153
154 semanage permissive can also be used to manipulate whether or not a
155 process type is permissive.
156
157 semanage module can also be used to enable/disable/install/remove pol‐
158 icy modules.
159
160 semanage boolean can also be used to manipulate the booleans
161
162
163 system-config-selinux is a GUI tool available to customize SELinux pol‐
164 icy settings.
