NAME

6       bluetooth_selinux  -  Security  Enhanced Linux Policy for the bluetooth
7       processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the bluetooth  processes  via  flexible
11       mandatory access control.
12
13       The  bluetooth processes execute with the bluetooth_t SELinux type. You
14       can check if you have these processes running by executing the ps  com‐
15       mand with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep bluetooth_t
20
21
22

ENTRYPOINTS

24       The  bluetooth_t  SELinux  type can be entered via the bluetooth_exec_t
25       file type.
26
27       The default entrypoint paths for the bluetooth_t domain are the follow‐
28       ing:
29
30       /usr/bin/dund,     /usr/bin/hidd,     /usr/bin/pand,    /usr/sbin/hcid,
31       /usr/sbin/sdpd,  /usr/bin/rfcomm,  /usr/sbin/hid2hci,  /usr/sbin/hciat‐
32       tach, /usr/sbin/bluetoothd, /usr/libexec/bluetooth/bluetoothd
33

PROCESS TYPES

35       SELinux defines process types (domains) for each process running on the
36       system
37
38       You can see the context of a process using the -Z option to ps
39
40       Policy governs the access confined processes have  to  files.   SELinux
41       bluetooth  policy  is very flexible allowing users to setup their blue‐
42       tooth processes in as secure a method as possible.
43
44       The following process types are defined for bluetooth:
45
46       bluetooth_t, bluetooth_helper_t
47
48       Note: semanage permissive -a  bluetooth_t  can  be  used  to  make  the
49       process  type  bluetooth_t  permissive. SELinux does not deny access to
50       permissive process types, but the AVC (SELinux  denials)  messages  are
51       still generated.
52
53

BOOLEANS

55       SELinux  policy  is customizable based on least access required.  blue‐
56       tooth policy is extremely flexible and has several booleans that  allow
57       you to manipulate the policy and run bluetooth with the tightest access
58       possible.
59
60
61
62       If you want to allow users to resolve user passwd entries directly from
63       ldap  rather  then  using  a  sssd server, you must turn on the authlo‐
64       gin_nsswitch_use_ldap boolean. Disabled by default.
65
66       setsebool -P authlogin_nsswitch_use_ldap 1
67
68
69
70       If you want to deny all system processes and Linux users to  use  blue‐
71       tooth wireless technology, you must turn on the deny_bluetooth boolean.
72       Enabled by default.
73
74       setsebool -P deny_bluetooth 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 confined applications to run with kerberos, you
86       must turn on the kerberos_enabled boolean. Disabled by default.
87
88       setsebool -P kerberos_enabled 1
89
90
91
92       If you want to allow system to run with  NIS,  you  must  turn  on  the
93       nis_enabled boolean. Disabled by default.
94
95       setsebool -P nis_enabled 1
96
97
98
99       If  you  want to allow confined applications to use nscd shared memory,
100       you must turn on the nscd_use_shm boolean. Disabled by default.
101
102       setsebool -P nscd_use_shm 1
103
104
105
106       If you want to allow xguest to use blue tooth devices, you must turn on
107       the xguest_use_bluetooth boolean. Enabled by default.
108
109       setsebool -P xguest_use_bluetooth 1
110

MANAGED FILES

114       The  SELinux process type bluetooth_t can manage files labeled with the
115       following file types.  The paths listed are the default paths for these
116       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

182       SELinux requires files to have an extended attribute to define the file
183       type.
184
185       You can see the context of a file using the -Z option to ls
186
187       Policy governs the access  confined  processes  have  to  these  files.
188       SELinux bluetooth policy is very flexible allowing users to setup their
189       bluetooth processes in as secure a method as possible.
190
191       STANDARD FILE CONTEXT
192
193       SELinux defines the file context types for the bluetooth, if you wanted
194       to store files with these types in a diffent paths, you need to execute
195       the semanage command  to  sepecify  alternate  labeling  and  then  use
196       restorecon to put the labels on disk.
197
198       semanage  fcontext  -a  -t bluetooth_unit_file_t '/srv/mybluetooth_con‐
199       tent(/.*)?'
200       restorecon -R -v /srv/mybluetooth_content
201
202       Note: SELinux often uses regular expressions  to  specify  labels  that
203       match multiple files.
204
205       The following file types are defined for bluetooth:
206
207
208
209       bluetooth_conf_rw_t

215
216       bluetooth_conf_t
217
218       - Set files with the bluetooth_conf_t type, if you want  to  treat  the
219       files  as  bluetooth  configuration data, usually stored under the /etc
220       directory.
221
222
223
224       bluetooth_exec_t

240
241
242
243       bluetooth_helper_tmp_t
244
245       - Set files with the bluetooth_helper_tmp_t type, if you want to  store
246       bluetooth helper temporary files in the /tmp directories.
247
248
249
250       bluetooth_helper_tmpfs_t
251
252       -  Set  files  with  the  bluetooth_helper_tmpfs_t type, if you want to
253       store bluetooth helper files on a tmpfs file system.
254
255
256
257       bluetooth_initrc_exec_t
258
259       - Set files with the bluetooth_initrc_exec_t type, if you want to tran‐
260       sition an executable to the bluetooth_initrc_t domain.

263       Paths:
264            /etc/rc.d/init.d/dund,                      /etc/rc.d/init.d/pand,
265            /etc/rc.d/init.d/bluetooth
266
267
268       bluetooth_lock_t

271       files as bluetooth lock data, stored under the /var/lock directory
272
273
274
275       bluetooth_tmp_t
276
277       -  Set  files with the bluetooth_tmp_t type, if you want to store blue‐

280
281
282       bluetooth_unit_file_t
283
284       - Set files with the bluetooth_unit_file_t type, if you want  to  treat
285       the files as bluetooth unit content.
286
287
288
289       bluetooth_var_lib_t
290
291       - Set files with the bluetooth_var_lib_t type, if you want to store the

303            /var/run/sdp, /var/run/bluetoothd_address
304
305
306       Note:  File context can be temporarily modified with the chcon command.
307       If you want to permanently change the file context you need to use  the
308       semanage fcontext command.  This will modify the SELinux labeling data‐
309       base.  You will need to use restorecon to apply the labels.
310
311

COMMANDS

313       semanage fcontext can also be used to manipulate default  file  context
314       mappings.
315
316       semanage  permissive  can  also  be used to manipulate whether or not a
317       process type is permissive.
318
319       semanage module can also be used to enable/disable/install/remove  pol‐
320       icy modules.
321
322       semanage boolean can also be used to manipulate the booleans
323
324
325       system-config-selinux is a GUI tool available to customize SELinux pol‐
326       icy settings.
