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
48 access 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 users to resolve user passwd entries directly from
61 ldap rather then using a sssd server, you must turn on the authlo‐
62 gin_nsswitch_use_ldap boolean. Disabled by default.
63 setsebool -P authlogin_nsswitch_use_ldap 1
65 If you want to allow all domains to execute in fips_mode, you must turn
69 on the fips_mode boolean. Enabled by default.
70 setsebool -P fips_mode 1
72 If you want to allow confined applications to run with kerberos, you
76 must turn on the kerberos_enabled boolean. Disabled by default.
77 setsebool -P kerberos_enabled 1
79 If you want to allow system to run with NIS, you must turn on the
83 nis_enabled boolean. Disabled by default.
84 setsebool -P nis_enabled 1
86 If you want to allow confined applications to use nscd shared memory,
90 you must turn on the nscd_use_shm boolean. Disabled by default.
91 setsebool -P nscd_use_shm 1
93 If you want to allow regular users direct dri device access, you must
97 turn on the selinuxuser_direct_dri_enabled boolean. Disabled by
98 default.
99 setsebool -P selinuxuser_direct_dri_enabled 1
101 If you want to allows clients to write to the X server shared memory
105 segments, you must turn on the xserver_clients_write_xshm boolean. Dis‐
106 abled by default.
107 setsebool -P xserver_clients_write_xshm 1
109
113 The SELinux process type bluetooth_helper_t can manage files labeled
114 with the following file types. The paths listed are the default paths
115 for these file types. Note the processes UID still need to have DAC
116 permissions.
117 bluetooth_helper_tmp_t
119 bluetooth_helper_tmpfs_t
122 user_fonts_cache_t
125 /root/.fontconfig(/.*)?
127 /root/.fonts/auto(/.*)?
128 /root/.fonts.cache-.*
129 /root/.cache/fontconfig(/.*)?
130 /home/[^/]+/.fontconfig(/.*)?
131 /home/[^/]+/.fonts/auto(/.*)?
132 /home/[^/]+/.fonts.cache-.*
133 /home/[^/]+/.cache/fontconfig(/.*)?
134 xserver_tmpfs_t

140 SELinux requires files to have an extended attribute to define the file
141 type.
142 You can see the context of a file using the -Z option to ls
144 Policy governs the access confined processes have to these files.
146 SELinux bluetooth_helper policy is very flexible allowing users to set‐
147 up their bluetooth_helper processes in as secure a method as possible.
148 STANDARD FILE CONTEXT
150 SELinux defines the file context types for the bluetooth_helper, if you
152 wanted to store files with these types in a diffent paths, you need to
153 execute the semanage command to sepecify alternate labeling and then
154 use restorecon to put the labels on disk.
155 semanage fcontext -a -t bluetooth_helper_tmpfs_t '/srv/myblue‐
157 tooth_helper_content(/.*)?'
158 restorecon -R -v /srv/mybluetooth_helper_content
159 Note: SELinux often uses regular expressions to specify labels that
161 match multiple files.
162 The following file types are defined for bluetooth_helper:
164 bluetooth_helper_exec_t
168 - Set files with the bluetooth_helper_exec_t type, if you want to tran‐
170 sition an executable to the bluetooth_helper_t domain.
171 bluetooth_helper_tmp_t
175 - Set files with the bluetooth_helper_tmp_t type, if you want to store
177 bluetooth helper temporary files in the /tmp directories.
178 bluetooth_helper_tmpfs_t
182 - Set files with the bluetooth_helper_tmpfs_t type, if you want to
184 store bluetooth helper files on a tmpfs file system.
185 Note: File context can be temporarily modified with the chcon command.
189 If you want to permanently change the file context you need to use the
190 semanage fcontext command. This will modify the SELinux labeling data‐
191 base. You will need to use restorecon to apply the labels.
192
195 semanage fcontext can also be used to manipulate default file context
196 mappings.
197 semanage permissive can also be used to manipulate whether or not a
199 process type is permissive.
200 semanage module can also be used to enable/disable/install/remove pol‐
202 icy modules.
203 semanage boolean can also be used to manipulate the booleans
205 system-config-selinux is a GUI tool available to customize SELinux pol‐
208 icy settings.
