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 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 confined applications to run with kerberos, you
68       must turn on the allow_kerberos boolean. Enabled by default.
69
70       setsebool -P allow_kerberos 1
71
72
73
74       If you want to allow sysadm to debug or ptrace all processes, you  must
75       turn on the allow_ptrace boolean. Disabled by default.
76
77       setsebool -P allow_ptrace 1
78
79
80
81       If  you  want  to  allow  system  to run with NIS, you must turn on the
82       allow_ypbind boolean. Disabled by default.
83
84       setsebool -P allow_ypbind 1
85
86
87
88       If you want to allow all domains to have the kernel load  modules,  you
89       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
90       default.
91
92       setsebool -P domain_kernel_load_modules 1
93
94
95
96       If you want to allow all domains to execute in fips_mode, you must turn
97       on the fips_mode boolean. Enabled by default.
98
99       setsebool -P fips_mode 1
100
101
102
103       If you want to enable reading of urandom for all domains, you must turn
104       on the global_ssp boolean. Disabled by default.
105
106       setsebool -P global_ssp 1
107
108
109
110       If you want to allow confined applications to use nscd  shared  memory,
111       you must turn on the nscd_use_shm boolean. Enabled by default.
112
113       setsebool -P nscd_use_shm 1
114
115
116

PORT TYPES

118       SELinux defines port types to represent TCP and UDP ports.
119
120       You  can  see  the  types associated with a port by using the following
121       command:
122
123       semanage port -l
124
125
126       Policy governs the access  confined  processes  have  to  these  ports.
127       SELinux  stunnel  policy is very flexible allowing users to setup their
128       stunnel processes in as secure a method as possible.
129
130       The following port types are defined for stunnel:
131
132
133       stunnel_port_t
134
135
136
137       MANAGED FILES
138
139              The SELinux process type stunnel_t can manage files labeled with
140              the  following  file  types.   The  paths listed are the default
141              paths for these file types.  Note the processes UID  still  need
142              to have DAC permissions.
143
144              initrc_tmp_t
145
146
147              mnt_t

150                   /mnt(/[^/]*)?
151                   /rhev(/[^/]*)?
152                   /media(/[^/]*)
153                   /media(/[^/]*)?
154                   /etc/rhgb(/.*)?
155                   /media/.hal-.*

FILE CONTEXTS

179       SELinux requires files to have an extended attribute to define the file
180       type.
181
182       You can see the context of a file using the -Z option to ls
183
184       Policy governs the access  confined  processes  have  to  these  files.
185       SELinux  stunnel  policy is very flexible allowing users to setup their
186       stunnel processes in as secure a method as possible.
187
188       STANDARD FILE CONTEXT
189
190       SELinux defines the file context types for the stunnel, if  you  wanted
191       to store files with these types in a diffent paths, you need to execute
192       the semanage command  to  sepecify  alternate  labeling  and  then  use
193       restorecon to put the labels on disk.
194
195       semanage   fcontext   -a   -t   stunnel_var_run_t  '/srv/mystunnel_con‐
196       tent(/.*)?'
197       restorecon -R -v /srv/mystunnel_content
198
199       Note: SELinux often uses regular expressions  to  specify  labels  that
200       match multiple files.
201
202       The following file types are defined for stunnel:
203
204
205
206       stunnel_etc_t
207
208       -  Set  files with the stunnel_etc_t type, if you want to store stunnel
209       files in the /etc directories.
210
211
212
213       stunnel_exec_t
214
215       - Set files with the stunnel_exec_t type, if you want to transition  an
216       executable to the stunnel_t domain.
217
218
219       Paths:
220            /usr/bin/stunnel, /usr/sbin/stunnel
221
222
223       stunnel_tmp_t
224
225       -  Set  files with the stunnel_tmp_t type, if you want to store stunnel
226       temporary files in the /tmp directories.
227
228
229
230       stunnel_var_run_t
231
232       - Set files with the stunnel_var_run_t type, if you want to  store  the
233       stunnel files under the /run or /var/run directory.
234
235
236
237       Note:  File context can be temporarily modified with the chcon command.
238       If you want to permanently change the file context you need to use  the
239       semanage fcontext command.  This will modify the SELinux labeling data‐
240       base.  You will need to use restorecon to apply the labels.
241
242

COMMANDS

244       semanage fcontext can also be used to manipulate default  file  context
245       mappings.
246
247       semanage  permissive  can  also  be used to manipulate whether or not a
248       process type is permissive.
249
250       semanage module can also be used to enable/disable/install/remove  pol‐
251       icy modules.
252
253       semanage port can also be used to manipulate the port definitions
254
255       semanage boolean can also be used to manipulate the booleans
256
257
258       system-config-selinux is a GUI tool available to customize SELinux pol‐
259       icy settings.
