6 stunnel_selinux - Security Enhanced Linux Policy for the stunnel pro‐
7 cesses
8
10 Security-Enhanced Linux secures the stunnel processes via flexible
11 mandatory access control.
12
13 The stunnel processes execute with the stunnel_t SELinux type. You can
14 check if you have these processes running by executing the ps command
15 with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep stunnel_t
20
21
22
24 The stunnel_t SELinux type can be entered via the stunnel_exec_t file
25 type.
26
27 The default entrypoint paths for the stunnel_t domain are the follow‐
28 ing:
29
30 /usr/bin/stunnel, /usr/sbin/stunnel
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 stunnel policy is very flexible allowing users to setup their stunnel
40 processes in as secure a method as possible.
41
42 The following process types are defined for stunnel:
43
44 stunnel_t
45
46 Note: semanage permissive -a stunnel_t can be used to make the process
47 type stunnel_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. stunnel
54 policy is extremely flexible and has several booleans that allow you to
55 manipulate the policy and run stunnel with the tightest access possi‐
56 ble.
57
58
59
60 If you want to dontaudit all daemons scheduling requests (setsched,
61 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
62 Enabled by default.
63
64 setsebool -P daemons_dontaudit_scheduling 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 system to run with NIS, you must turn on the
76 nis_enabled boolean. Disabled by default.
77
78 setsebool -P nis_enabled 1
79
80
81
83 SELinux defines port types to represent TCP and UDP ports.
84
85 You can see the types associated with a port by using the following
86 command:
87
88 semanage port -l
89
90
91 Policy governs the access confined processes have to these ports.
92 SELinux stunnel policy is very flexible allowing users to setup their
93 stunnel processes in as secure a method as possible.
94
95 The following port types are defined for stunnel:
96
97
98 stunnel_port_t
99
100
101
102 MANAGED FILES
103
104 The SELinux process type stunnel_t can manage files labeled with
105 the following file types. The paths listed are the default
106 paths for these file types. Note the processes UID still need
107 to have DAC permissions.

172 SELinux requires files to have an extended attribute to define the file
173 type.
174
175 You can see the context of a file using the -Z option to ls
176
177 Policy governs the access confined processes have to these files.
178 SELinux stunnel policy is very flexible allowing users to setup their
179 stunnel processes in as secure a method as possible.
180
181 STANDARD FILE CONTEXT
182
183 SELinux defines the file context types for the stunnel, if you wanted
184 to store files with these types in a different paths, you need to exe‐
185 cute the semanage command to specify alternate labeling and then use
186 restorecon to put the labels on disk.
187
188 semanage fcontext -a -t stunnel_exec_t '/srv/stunnel/content(/.*)?'
189 restorecon -R -v /srv/mystunnel_content
190
191 Note: SELinux often uses regular expressions to specify labels that
192 match multiple files.
193
194 The following file types are defined for stunnel:
195
196
197
198 stunnel_etc_t
199
200 - Set files with the stunnel_etc_t type, if you want to store stunnel
201 files in the /etc directories.
202
203
204
205 stunnel_exec_t
206
207 - Set files with the stunnel_exec_t type, if you want to transition an
208 executable to the stunnel_t domain.
209
210
211 Paths:
212 /usr/bin/stunnel, /usr/sbin/stunnel
213
214
215 stunnel_log_t
216
217 - Set files with the stunnel_log_t type, if you want to treat the data
218 as stunnel log data, usually stored under the /var/log directory.
219
220
221
222 stunnel_tmp_t
223
224 - Set files with the stunnel_tmp_t type, if you want to store stunnel
225 temporary files in the /tmp directories.
226
227
228
229 stunnel_var_run_t
230
231 - Set files with the stunnel_var_run_t type, if you want to store the
232 stunnel files under the /run or /var/run directory.
233
234
235
236 Note: File context can be temporarily modified with the chcon command.
237 If you want to permanently change the file context you need to use the
238 semanage fcontext command. This will modify the SELinux labeling data‐
239 base. You will need to use restorecon to apply the labels.
240
241
243 semanage fcontext can also be used to manipulate default file context
244 mappings.
245
246 semanage permissive can also be used to manipulate whether or not a
247 process type is permissive.
248
249 semanage module can also be used to enable/disable/install/remove pol‐
250 icy modules.
251
252 semanage port can also be used to manipulate the port definitions
253
254 semanage boolean can also be used to manipulate the booleans
255
256
257 system-config-selinux is a GUI tool available to customize SELinux pol‐
258 icy settings.
