6 tor_selinux - Security Enhanced Linux Policy for the tor processes
7
9 Security-Enhanced Linux secures the tor processes via flexible manda‐
10 tory access control.
11 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 For example:
17 ps -eZ | grep tor_t
19
23 The tor_t SELinux type can be entered via the tor_exec_t file type.
24 The default entrypoint paths for the tor_t domain are the following:
26 /usr/bin/tor, /usr/sbin/tor
28
30 SELinux defines process types (domains) for each process running on the
31 system
32 You can see the context of a process using the -Z option to ps
34 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 The following process types are defined for tor:
40 tor_t
42 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
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 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 setsebool -P tor_bind_all_unreserved_ports 1
60 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 setsebool -P tor_can_network_relay 1
67 If you want to allow tor to run onion services, you must turn on the
71 tor_can_onion_services boolean. Disabled by default.
72 setsebool -P tor_can_onion_services 1
74 If you want to allow users to resolve user passwd entries directly from
78 ldap rather then using a sssd server, you must turn on the authlo‐
79 gin_nsswitch_use_ldap boolean. Disabled by default.
80 setsebool -P authlogin_nsswitch_use_ldap 1
82 If you want to allow all domains to execute in fips_mode, you must turn
86 on the fips_mode boolean. Enabled by default.
87 setsebool -P fips_mode 1
89 If you want to allow confined applications to run with kerberos, you
93 must turn on the kerberos_enabled boolean. Enabled by default.
94 setsebool -P kerberos_enabled 1
96 If you want to allow system to run with NIS, you must turn on the
100 nis_enabled boolean. Disabled by default.
101 setsebool -P nis_enabled 1
103 If you want to allow confined applications to use nscd shared memory,
107 you must turn on the nscd_use_shm boolean. Enabled by default.
108 setsebool -P nscd_use_shm 1
110
114 SELinux defines port types to represent TCP and UDP ports.
115 You can see the types associated with a port by using the following
117 command:
118 semanage port -l
120 Policy governs the access confined processes have to these ports.
123 SELinux tor policy is very flexible allowing users to setup their tor
124 processes in as secure a method as possible.
125 The following port types are defined for tor:
127 tor_port_t
130 Default Defined Ports:
134 tcp 6969,9001,9030,9050,9051,9150
135
137 The SELinux process type tor_t can manage files labeled with the fol‐
138 lowing file types. The paths listed are the default paths for these
139 file types. Note the processes UID still need to have DAC permissions.

187 SELinux requires files to have an extended attribute to define the file
188 type.
189 You can see the context of a file using the -Z option to ls
191 Policy governs the access confined processes have to these files.
193 SELinux tor policy is very flexible allowing users to setup their tor
194 processes in as secure a method as possible.
195 EQUIVALENCE DIRECTORIES
197 tor policy stores data with multiple different file context types under
200 the /var/lib/tor directory. If you would like to store the data in a
201 different directory you can use the semanage command to create an
202 equivalence mapping. If you wanted to store this data under the /srv
203 dirctory you would execute the following command:
204 semanage fcontext -a -e /var/lib/tor /srv/tor
206 restorecon -R -v /srv/tor
207 STANDARD FILE CONTEXT
209 SELinux defines the file context types for the tor, if you wanted to
211 store files with these types in a diffent paths, you need to execute
212 the semanage command to sepecify alternate labeling and then use
213 restorecon to put the labels on disk.
214 semanage fcontext -a -t tor_unit_file_t '/srv/mytor_content(/.*)?'
216 restorecon -R -v /srv/mytor_content
217 Note: SELinux often uses regular expressions to specify labels that
219 match multiple files.
220 The following file types are defined for tor:
222 tor_etc_t
226 - Set files with the tor_etc_t type, if you want to store tor files in
228 the /etc directories.
229 tor_exec_t
233 - Set files with the tor_exec_t type, if you want to transition an exe‐
235 cutable to the tor_t domain.
236 Paths:
239 /usr/bin/tor, /usr/sbin/tor
240 tor_initrc_exec_t
243 - Set files with the tor_initrc_exec_t type, if you want to transition
245 an executable to the tor_initrc_t domain.
246 tor_unit_file_t
250 - Set files with the tor_unit_file_t type, if you want to treat the
252 files as tor unit content.
253 tor_var_lib_t
257 - Set files with the tor_var_lib_t type, if you want to store the tor
259 files under the /var/lib directory.
260 Paths:
263 /var/lib/tor(/.*)?, /var/lib/tor-data(/.*)?
264 tor_var_log_t
267 - Set files with the tor_var_log_t type, if you want to treat the data
269 as tor var log data, usually stored under the /var/log directory.
270 tor_var_run_t
274 - Set files with the tor_var_run_t type, if you want to store the tor
276 files under the /run or /var/run directory.
277 Note: File context can be temporarily modified with the chcon command.
281 If you want to permanently change the file context you need to use the
282 semanage fcontext command. This will modify the SELinux labeling data‐
283 base. You will need to use restorecon to apply the labels.
284
287 semanage fcontext can also be used to manipulate default file context
288 mappings.
289 semanage permissive can also be used to manipulate whether or not a
291 process type is permissive.
292 semanage module can also be used to enable/disable/install/remove pol‐
294 icy modules.
295 semanage port can also be used to manipulate the port definitions
297 semanage boolean can also be used to manipulate the booleans
299 system-config-selinux is a GUI tool available to customize SELinux pol‐
302 icy settings.
