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. Enabled 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. Enabled by default.
98 setsebool -P selinuxuser_direct_dri_enabled 1
100 If you want to allows clients to write to the X server shared memory
104 segments, you must turn on the xserver_clients_write_xshm boolean. Dis‐
105 abled by default.
106 setsebool -P xserver_clients_write_xshm 1
108
112 The SELinux process type bluetooth_helper_t can manage files labeled
113 with the following file types. The paths listed are the default paths
114 for these file types. Note the processes UID still need to have DAC
115 permissions.
116 bluetooth_helper_tmp_t
118 bluetooth_helper_tmpfs_t
121 user_fonts_cache_t
124 /root/.fontconfig(/.*)?
126 /root/.fonts/auto(/.*)?
127 /root/.fonts.cache-.*
128 /root/.cache/fontconfig(/.*)?
129 /home/[^/]+/.fontconfig(/.*)?
130 /home/[^/]+/.fonts/auto(/.*)?
131 /home/[^/]+/.fonts.cache-.*
132 /home/[^/]+/.cache/fontconfig(/.*)?
133 xserver_tmpfs_t
135
139 SELinux requires files to have an extended attribute to define the file
140 type.
141 You can see the context of a file using the -Z option to ls
143 Policy governs the access confined processes have to these files.
145 SELinux bluetooth_helper policy is very flexible allowing users to set‐
146 up their bluetooth_helper processes in as secure a method as possible.
147 STANDARD FILE CONTEXT
149 SELinux defines the file context types for the bluetooth_helper, if you
151 wanted to store files with these types in a diffent paths, you need to
152 execute the semanage command to sepecify alternate labeling and then
153 use restorecon to put the labels on disk.
154 semanage fcontext -a -t bluetooth_helper_tmpfs_t '/srv/myblue‐
156 tooth_helper_content(/.*)?'
157 restorecon -R -v /srv/mybluetooth_helper_content
158 Note: SELinux often uses regular expressions to specify labels that
160 match multiple files.
161 The following file types are defined for bluetooth_helper:
163 bluetooth_helper_exec_t
167 - Set files with the bluetooth_helper_exec_t type, if you want to tran‐
169 sition an executable to the bluetooth_helper_t domain.
170 bluetooth_helper_tmp_t
174 - Set files with the bluetooth_helper_tmp_t type, if you want to store
176 bluetooth helper temporary files in the /tmp directories.
177 bluetooth_helper_tmpfs_t
181 - Set files with the bluetooth_helper_tmpfs_t type, if you want to
183 store bluetooth helper files on a tmpfs file system.
184 Note: File context can be temporarily modified with the chcon command.
188 If you want to permanently change the file context you need to use the
189 semanage fcontext command. This will modify the SELinux labeling data‐
190 base. You will need to use restorecon to apply the labels.
191
194 semanage fcontext can also be used to manipulate default file context
195 mappings.
196 semanage permissive can also be used to manipulate whether or not a
198 process type is permissive.
199 semanage module can also be used to enable/disable/install/remove pol‐
201 icy modules.
202 semanage boolean can also be used to manipulate the booleans
204 system-config-selinux is a GUI tool available to customize SELinux pol‐
207 icy settings.
