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 and udp sockets to
56       all  unreserved  ports,  you  must  turn  on   the   tor_bind_all_unre‐
57       served_ports boolean. 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 dontaudit all  daemons  scheduling  requests  (setsched,
71       sys_nice),  you  must turn on the daemons_dontaudit_scheduling boolean.
72       Enabled by default.
73
74       setsebool -P daemons_dontaudit_scheduling 1
75
76
77
78       If you want to allow all domains to execute in fips_mode, you must turn
79       on the fips_mode boolean. Enabled by default.
80
81       setsebool -P fips_mode 1
82
83
84
85       If  you  want  to  allow  system  to run with NIS, you must turn on the
86       nis_enabled boolean. Disabled by default.
87
88       setsebool -P nis_enabled 1
89
90
91

PORT TYPES

93       SELinux defines port types to represent TCP and UDP ports.
94
95       You can see the types associated with a port  by  using  the  following
96       command:
97
98       semanage port -l
99
100
101       Policy  governs  the  access  confined  processes  have to these ports.
102       SELinux tor policy is very flexible allowing users to setup  their  tor
103       processes in as secure a method as possible.
104
105       The following port types are defined for tor:
106
107
108       tor_port_t
109
110
111
112       Default Defined Ports:
113                 tcp 6969,9001,9030,9050,9051,9150
114

MANAGED FILES

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

FILE CONTEXTS

181       SELinux requires files to have an extended attribute to define the file
182       type.
183
184       You can see the context of a file using the -Z option to ls
185
186       Policy governs the access  confined  processes  have  to  these  files.
187       SELinux  tor  policy is very flexible allowing users to setup their tor
188       processes in as secure a method as possible.
189
190       EQUIVALENCE DIRECTORIES
191
192
193       tor policy stores data with multiple different file context types under
194       the  /var/lib/tor  directory.  If you would like to store the data in a
195       different directory you can use  the  semanage  command  to  create  an
196       equivalence  mapping.   If you wanted to store this data under the /srv
197       directory you would execute the following command:
198
199       semanage fcontext -a -e /var/lib/tor /srv/tor
200       restorecon -R -v /srv/tor
201
202       STANDARD FILE CONTEXT
203
204       SELinux defines the file context types for the tor, if  you  wanted  to
205       store  files with these types in a different paths, you need to execute
206       the semanage command to specify alternate labeling  and  then  use  re‐
207       storecon to put the labels on disk.
208
209       semanage fcontext -a -t tor_exec_t '/srv/tor/content(/.*)?'
210       restorecon -R -v /srv/mytor_content
211
212       Note:  SELinux  often  uses  regular expressions to specify labels that
213       match multiple files.
214
215       The following file types are defined for tor:
216
217
218
219       tor_etc_t
220
221       - Set files with the tor_etc_t type, if you want to store tor files  in
222       the /etc directories.
223
224
225
226       tor_exec_t
227
228       - Set files with the tor_exec_t type, if you want to transition an exe‐
229       cutable to the tor_t domain.
230
231
232       Paths:
233            /usr/bin/tor, /usr/sbin/tor
234
235
236       tor_initrc_exec_t
237
238       - Set files with the tor_initrc_exec_t type, if you want to  transition
239       an executable to the tor_initrc_t domain.
240
241
242
243       tor_unit_file_t
244
245       -  Set  files  with  the tor_unit_file_t type, if you want to treat the
246       files as tor unit content.
247
248
249
250       tor_var_lib_t
251
252       - Set files with the tor_var_lib_t type, if you want to store  the  tor
253       files under the /var/lib directory.
254
255
256       Paths:
257            /var/lib/tor(/.*)?, /var/lib/tor-data(/.*)?
258
259
260       tor_var_log_t
261
262       -  Set files with the tor_var_log_t type, if you want to treat the data
263       as tor var log data, usually stored under the /var/log directory.
264
265
266
267       tor_var_run_t
268
269       - Set files with the tor_var_run_t type, if you want to store  the  tor
270       files under the /run or /var/run directory.
271
272
273
274       Note:  File context can be temporarily modified with the chcon command.
275       If you want to permanently change the file context you need to use  the
276       semanage fcontext command.  This will modify the SELinux labeling data‐
277       base.  You will need to use restorecon to apply the labels.
278
279

COMMANDS

281       semanage fcontext can also be used to manipulate default  file  context
282       mappings.
283
284       semanage  permissive  can  also  be used to manipulate whether or not a
285       process type is permissive.
286
287       semanage module can also be used to enable/disable/install/remove  pol‐
288       icy modules.
289
290       semanage port can also be used to manipulate the port definitions
291
292       semanage boolean can also be used to manipulate the booleans
293
294
295       system-config-selinux is a GUI tool available to customize SELinux pol‐
296       icy settings.
