NAME

6       tor_selinux - Security Enhanced Linux Policy for the tor processes
7

DESCRIPTION

9       Security-Enhanced  Linux  secures the tor processes via flexible manda‐
10       tory access control.
11
12       The tor processes execute with the tor_t SELinux type. You can check if
13       you  have  these processes running by executing the ps command with the
14       -Z qualifier.
15
16       For example:
17
18       ps -eZ | grep tor_t
19
20
21

ENTRYPOINTS

23       The tor_t SELinux type can be entered via the tor_exec_t file type.
24
25       The default entrypoint paths for the tor_t domain are the following:
26
27       /usr/bin/tor, /usr/sbin/tor
28

PROCESS TYPES

30       SELinux defines process types (domains) for each process running on the
31       system
32
33       You can see the context of a process using the -Z option to ps
34
35       Policy  governs  the  access confined processes have to files.  SELinux
36       tor policy is very flexible allowing users to setup their tor processes
37       in as secure a method as possible.
38
39       The following process types are defined for tor:
40
41       tor_t
42
43       Note: semanage permissive -a tor_t can be used to make the process type
44       tor_t permissive. SELinux does not deny access  to  permissive  process
45       types, but the AVC (SELinux denials) messages are still generated.
46
47

BOOLEANS

49       SELinux  policy  is  customizable  based on least access required.  tor
50       policy is extremely flexible and has several booleans that allow you to
51       manipulate the policy and run tor with the tightest access possible.
52
53
54
55       If  you want to determine whether tor can bind tcp sockets to all unre‐
56       served ports, you must turn on the tor_bind_all_unreserved_ports  bool‐
57       ean. Disabled by default.
58
59       setsebool -P tor_bind_all_unreserved_ports 1
60
61
62
63       If  you  want  to  allow  tor  to  act as a relay, you must turn on the
64       tor_can_network_relay boolean. Disabled by default.
65
66       setsebool -P tor_can_network_relay 1
67
68
69
70       If you want to allow all domains to execute in fips_mode, you must turn
71       on the fips_mode boolean. Enabled by default.
72
73       setsebool -P fips_mode 1
74
75
76

PORT TYPES

78       SELinux defines port types to represent TCP and UDP ports.
79
80       You  can  see  the  types associated with a port by using the following
81       command:
82
83       semanage port -l
84
85
86       Policy governs the access  confined  processes  have  to  these  ports.
87       SELinux  tor  policy is very flexible allowing users to setup their tor
88       processes in as secure a method as possible.
89
90       The following port types are defined for tor:
91
92
93       tor_port_t
94
95
96
97       Default Defined Ports:
98                 tcp 6969,9001,9030,9050,9051,9150
99

MANAGED FILES

101       The SELinux process type tor_t can manage files labeled with  the  fol‐
102       lowing  file  types.   The paths listed are the default paths for these
103       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

151       SELinux requires files to have an extended attribute to define the file
152       type.
153
154       You can see the context of a file using the -Z option to ls
155
156       Policy  governs  the  access  confined  processes  have to these files.
157       SELinux tor policy is very flexible allowing users to setup  their  tor
158       processes in as secure a method as possible.
159
160       EQUIVALENCE DIRECTORIES
161
162
163       tor policy stores data with multiple different file context types under
164       the /var/lib/tor directory.  If you would like to store the data  in  a
165       different  directory  you  can  use  the  semanage command to create an
166       equivalence mapping.  If you wanted to store this data under  the  /srv
167       directory you would execute the following command:
168
169       semanage fcontext -a -e /var/lib/tor /srv/tor
170       restorecon -R -v /srv/tor
171
172       STANDARD FILE CONTEXT
173
174       SELinux  defines  the  file context types for the tor, if you wanted to
175       store files with these types in a diffent paths, you  need  to  execute
176       the  semanage  command  to  sepecify  alternate  labeling  and then use
177       restorecon to put the labels on disk.
178
179       semanage fcontext -a -t tor_unit_file_t '/srv/mytor_content(/.*)?'
180       restorecon -R -v /srv/mytor_content
181
182       Note: SELinux often uses regular expressions  to  specify  labels  that
183       match multiple files.
184
185       The following file types are defined for tor:
186
187
188
189       tor_etc_t
190
191       -  Set files with the tor_etc_t type, if you want to store tor files in
192       the /etc directories.
193
194
195
196       tor_exec_t
197
198       - Set files with the tor_exec_t type, if you want to transition an exe‐
199       cutable to the tor_t domain.
200
201
202       Paths:
203            /usr/bin/tor, /usr/sbin/tor
204
205
206       tor_initrc_exec_t
207
208       -  Set files with the tor_initrc_exec_t type, if you want to transition
209       an executable to the tor_initrc_t domain.
210
211
212
213       tor_unit_file_t
214
215       - Set files with the tor_unit_file_t type, if you  want  to  treat  the
216       files as tor unit content.
217
218
219
220       tor_var_lib_t
221
222       -  Set  files with the tor_var_lib_t type, if you want to store the tor
223       files under the /var/lib directory.
224
225
226       Paths:
227            /var/lib/tor(/.*)?, /var/lib/tor-data(/.*)?
228
229
230       tor_var_log_t
231
232       - Set files with the tor_var_log_t type, if you want to treat the  data
233       as tor var log data, usually stored under the /var/log directory.
234
235
236
237       tor_var_run_t
238
239       -  Set  files with the tor_var_run_t type, if you want to store the tor
240       files under the /run or /var/run directory.
241
242
243
244       Note: File context can be temporarily modified with the chcon  command.
245       If  you want to permanently change the file context you need to use the
246       semanage fcontext command.  This will modify the SELinux labeling data‐
247       base.  You will need to use restorecon to apply the labels.
248
249

COMMANDS

251       semanage  fcontext  can also be used to manipulate default file context
252       mappings.
253
254       semanage permissive can also be used to manipulate  whether  or  not  a
255       process type is permissive.
256
257       semanage  module can also be used to enable/disable/install/remove pol‐
258       icy modules.
259
260       semanage port can also be used to manipulate the port definitions
261
262       semanage boolean can also be used to manipulate the booleans
263
264
265       system-config-selinux is a GUI tool available to customize SELinux pol‐
266       icy settings.
