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 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 For example:
18 ps -eZ | grep stunnel_t
20
24 The stunnel_t SELinux type can be entered via the stunnel_exec_t file
25 type.
26 The default entrypoint paths for the stunnel_t domain are the follow‐
28 ing:
29 /usr/bin/stunnel, /usr/sbin/stunnel
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 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 The following process types are defined for stunnel:
43 stunnel_t
45 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
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 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 setsebool -P fips_mode 1
64
68 SELinux defines port types to represent TCP and UDP ports.
69 You can see the types associated with a port by using the following
71 command:
72 semanage port -l
74 Policy governs the access confined processes have to these ports.
77 SELinux stunnel policy is very flexible allowing users to setup their
78 stunnel processes in as secure a method as possible.
79 The following port types are defined for stunnel:
81 stunnel_port_t
84 MANAGED FILES
88 The SELinux process type stunnel_t can manage files labeled with
90 the following file types. The paths listed are the default
91 paths for these file types. Note the processes UID still need
92 to have DAC permissions.
93 cluster_conf_t
95 /etc/cluster(/.*)?
97 cluster_var_lib_t
99 /var/lib/pcsd(/.*)?
101 /var/lib/cluster(/.*)?
102 /var/lib/openais(/.*)?
103 /var/lib/pengine(/.*)?
104 /var/lib/corosync(/.*)?
105 /usr/lib/heartbeat(/.*)?
106 /var/lib/heartbeat(/.*)?
107 /var/lib/pacemaker(/.*)?

132 stunnel_var_run_t

139 SELinux requires files to have an extended attribute to define the file
140 type.
141 You can see the context of a file using the -Z option to ls
143 Policy governs the access confined processes have to these files.
145 SELinux stunnel policy is very flexible allowing users to setup their
146 stunnel processes in as secure a method as possible.
147 STANDARD FILE CONTEXT
149 SELinux defines the file context types for the stunnel, if you wanted
151 to store files with these types in a diffent paths, you need to execute
152 the semanage command to sepecify alternate labeling and then use
153 restorecon to put the labels on disk.
154 semanage fcontext -a -t stunnel_var_run_t '/srv/mystunnel_con‐
156 tent(/.*)?'
157 restorecon -R -v /srv/mystunnel_content
158 Note: SELinux often uses regular expressions to specify labels that
160 match multiple files.
161 The following file types are defined for stunnel:
163 stunnel_etc_t
167 - Set files with the stunnel_etc_t type, if you want to store stunnel
169 files in the /etc directories.
170 stunnel_exec_t
174 - Set files with the stunnel_exec_t type, if you want to transition an
176 executable to the stunnel_t domain.
177 Paths:
180 /usr/bin/stunnel, /usr/sbin/stunnel
181 stunnel_log_t
184 - Set files with the stunnel_log_t type, if you want to treat the data
186 as stunnel log data, usually stored under the /var/log directory.
187 stunnel_tmp_t
191 - Set files with the stunnel_tmp_t type, if you want to store stunnel
193 temporary files in the /tmp directories.
194 stunnel_var_run_t
198 - Set files with the stunnel_var_run_t type, if you want to store the
200 stunnel files under the /run or /var/run directory.
201 Note: File context can be temporarily modified with the chcon command.
205 If you want to permanently change the file context you need to use the
206 semanage fcontext command. This will modify the SELinux labeling data‐
207 base. You will need to use restorecon to apply the labels.
208
211 semanage fcontext can also be used to manipulate default file context
212 mappings.
213 semanage permissive can also be used to manipulate whether or not a
215 process type is permissive.
216 semanage module can also be used to enable/disable/install/remove pol‐
218 icy modules.
219 semanage port can also be used to manipulate the port definitions
221 semanage boolean can also be used to manipulate the booleans
223 system-config-selinux is a GUI tool available to customize SELinux pol‐
226 icy settings.
