NAME

6       stunnel_selinux  -  Security Enhanced Linux Policy for the stunnel pro‐
7       cesses
8

DESCRIPTION

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

ENTRYPOINTS

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

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       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

BOOLEANS

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 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

PORT TYPES

97       SELinux defines port types to represent TCP and UDP ports.
98
99       You can see the types associated with a port  by  using  the  following
100       command:
101
102       semanage port -l
103
104
105       Policy  governs  the  access  confined  processes  have to these ports.
106       SELinux stunnel policy is very flexible allowing users to  setup  their
107       stunnel processes in as secure a method as possible.
108
109       The following port types are defined for stunnel:
110
111
112       stunnel_port_t
113
114
115
116       MANAGED FILES
117
118              The SELinux process type stunnel_t can manage files labeled with
119              the following file types.  The  paths  listed  are  the  default
120              paths  for  these file types.  Note the processes UID still need
121              to have DAC permissions.

FILE CONTEXTS

171       SELinux requires files to have an extended attribute to define the file
172       type.
173
174       You can see the context of a file using the -Z option to ls
175
176       Policy  governs  the  access  confined  processes  have to these files.
177       SELinux stunnel policy is very flexible allowing users to  setup  their
178       stunnel processes in as secure a method as possible.
179
180       STANDARD FILE CONTEXT
181
182       SELinux  defines  the file context types for the stunnel, if you wanted
183       to store files with these types in a diffent paths, you need to execute
184       the  semanage  command  to  sepecify  alternate  labeling  and then use
185       restorecon to put the labels on disk.
186
187       semanage  fcontext   -a   -t   stunnel_var_run_t   '/srv/mystunnel_con‐
188       tent(/.*)?'
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

COMMANDS

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.
