6 bluetooth_helper_selinux - Security Enhanced Linux Policy for the blue‐
7 tooth_helper processes
8
10 Security-Enhanced Linux secures the bluetooth_helper processes via
11 flexible mandatory access control.
12 The bluetooth_helper processes execute with the bluetooth_helper_t
14 SELinux type. You can check if you have these processes running by exe‐
15 cuting the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep bluetooth_helper_t
20
24 The bluetooth_helper_t SELinux type can be entered via the blue‐
25 tooth_helper_exec_t file type.
26 The default entrypoint paths for the bluetooth_helper_t domain are the
28 following:
29 /usr/bin/blue.*pin
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 bluetooth_helper policy is very flexible allowing users to setup their
40 bluetooth_helper processes in as secure a method as possible.
41 The following process types are defined for bluetooth_helper:
43 bluetooth_helper_t
45 Note: semanage permissive -a bluetooth_helper_t can be used to make the
47 process type bluetooth_helper_t permissive. SELinux does not deny ac‐
48 cess to permissive process types, but the AVC (SELinux denials) mes‐
49 sages are still generated.
50
53 SELinux policy is customizable based on least access required. blue‐
54 tooth_helper policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run bluetooth_helper with the
56 tightest access possible.
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 If you want to allow system to run with NIS, you must turn on the
68 nis_enabled boolean. Disabled by default.
69 setsebool -P nis_enabled 1
71 If you want to allow regular users direct dri device access, you must
75 turn on the selinuxuser_direct_dri_enabled boolean. Enabled by default.
76 setsebool -P selinuxuser_direct_dri_enabled 1
78 If you want to allows clients to write to the X server shared memory
82 segments, you must turn on the xserver_clients_write_xshm boolean. Dis‐
83 abled by default.
84 setsebool -P xserver_clients_write_xshm 1
86
90 The SELinux process type bluetooth_helper_t can manage files labeled
91 with the following file types. The paths listed are the default paths
92 for these file types. Note the processes UID still need to have DAC
93 permissions.
94 bluetooth_helper_tmp_t
96 bluetooth_helper_tmpfs_t
99 krb5_host_rcache_t
102 /var/tmp/krb5_0.rcache2

128 SELinux requires files to have an extended attribute to define the file
129 type.
130 You can see the context of a file using the -Z option to ls
132 Policy governs the access confined processes have to these files.
134 SELinux bluetooth_helper policy is very flexible allowing users to
135 setup their bluetooth_helper processes in as secure a method as possi‐
136 ble.
137 STANDARD FILE CONTEXT
139 SELinux defines the file context types for the bluetooth_helper, if you
141 wanted to store files with these types in a diffent paths, you need to
142 execute the semanage command to specify alternate labeling and then use
143 restorecon to put the labels on disk.
144 semanage fcontext -a -t bluetooth_helper_tmpfs_t '/srv/myblue‐
146 tooth_helper_content(/.*)?'
147 restorecon -R -v /srv/mybluetooth_helper_content
148 Note: SELinux often uses regular expressions to specify labels that
150 match multiple files.
151 The following file types are defined for bluetooth_helper:
153 bluetooth_helper_exec_t
157 - Set files with the bluetooth_helper_exec_t type, if you want to tran‐
159 sition an executable to the bluetooth_helper_t domain.
160 bluetooth_helper_tmp_t
164 - Set files with the bluetooth_helper_tmp_t type, if you want to store
166 bluetooth helper temporary files in the /tmp directories.
167 bluetooth_helper_tmpfs_t
171 - Set files with the bluetooth_helper_tmpfs_t type, if you want to
173 store bluetooth helper files on a tmpfs file system.
174 Note: File context can be temporarily modified with the chcon command.
178 If you want to permanently change the file context you need to use the
179 semanage fcontext command. This will modify the SELinux labeling data‐
180 base. You will need to use restorecon to apply the labels.
181
184 semanage fcontext can also be used to manipulate default file context
185 mappings.
186 semanage permissive can also be used to manipulate whether or not a
188 process type is permissive.
189 semanage module can also be used to enable/disable/install/remove pol‐
191 icy modules.
192 semanage boolean can also be used to manipulate the booleans
194 system-config-selinux is a GUI tool available to customize SELinux pol‐
197 icy settings.
