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 deny any process from ptracing or debugging any other
69 processes, you must turn on the deny_ptrace boolean. Enabled by
70 default.
71 setsebool -P deny_ptrace 1
73 If you want to allow any process to mmap any file on system with
77 attribute file_type, you must turn on the domain_can_mmap_files bool‐
78 ean. Enabled by default.
79 setsebool -P domain_can_mmap_files 1
81 If you want to allow all domains write to kmsg_device, while kernel is
85 executed with systemd.log_target=kmsg parameter, you must turn on the
86 domain_can_write_kmsg boolean. Disabled by default.
87 setsebool -P domain_can_write_kmsg 1
89 If you want to allow all domains to use other domains file descriptors,
93 you must turn on the domain_fd_use boolean. Enabled by default.
94 setsebool -P domain_fd_use 1
96 If you want to allow all domains to have the kernel load modules, you
100 must turn on the domain_kernel_load_modules boolean. Disabled by
101 default.
102 setsebool -P domain_kernel_load_modules 1
104 If you want to allow all domains to execute in fips_mode, you must turn
108 on the fips_mode boolean. Enabled by default.
109 setsebool -P fips_mode 1
111 If you want to enable reading of urandom for all domains, you must turn
115 on the global_ssp boolean. Disabled by default.
116 setsebool -P global_ssp 1
118 If you want to allow confined applications to run with kerberos, you
122 must turn on the kerberos_enabled boolean. Enabled by default.
123 setsebool -P kerberos_enabled 1
125 If you want to allow system to run with NIS, you must turn on the
129 nis_enabled boolean. Disabled by default.
130 setsebool -P nis_enabled 1
132 If you want to allow confined applications to use nscd shared memory,
136 you must turn on the nscd_use_shm boolean. Disabled by default.
137 setsebool -P nscd_use_shm 1
139 If you want to allow regular users direct dri device access, you must
143 turn on the selinuxuser_direct_dri_enabled boolean. Enabled by default.
144 setsebool -P selinuxuser_direct_dri_enabled 1
146 If you want to support NFS home directories, you must turn on the
150 use_nfs_home_dirs boolean. Disabled by default.
151 setsebool -P use_nfs_home_dirs 1
153 If you want to allows clients to write to the X server shared memory
157 segments, you must turn on the xserver_clients_write_xshm boolean. Dis‐
158 abled by default.
159 setsebool -P xserver_clients_write_xshm 1
161 If you want to support X userspace object manager, you must turn on the
165 xserver_object_manager boolean. Enabled by default.
166 setsebool -P xserver_object_manager 1
168
172 The SELinux process type bluetooth_helper_t can manage files labeled
173 with the following file types. The paths listed are the default paths
174 for these file types. Note the processes UID still need to have DAC
175 permissions.
176 bluetooth_helper_tmp_t
178 bluetooth_helper_tmpfs_t
181 user_fonts_cache_t
184 /root/.fontconfig(/.*)?
186 /root/.fonts/auto(/.*)?
187 /root/.fonts.cache-.*
188 /home/[^/]+/.fontconfig(/.*)?
189 /home/[^/]+/.fonts/auto(/.*)?
190 /home/[^/]+/.fonts.cache-.*
191 xserver_tmpfs_t
193
197 SELinux requires files to have an extended attribute to define the file
198 type.
199 You can see the context of a file using the -Z option to ls
201 Policy governs the access confined processes have to these files.
203 SELinux bluetooth_helper policy is very flexible allowing users to set‐
204 up their bluetooth_helper processes in as secure a method as possible.
205 STANDARD FILE CONTEXT
207 SELinux defines the file context types for the bluetooth_helper, if you
209 wanted to store files with these types in a diffent paths, you need to
210 execute the semanage command to sepecify alternate labeling and then
211 use restorecon to put the labels on disk.
212 semanage fcontext -a -t bluetooth_helper_tmpfs_t '/srv/myblue‐
214 tooth_helper_content(/.*)?'
215 restorecon -R -v /srv/mybluetooth_helper_content
216 Note: SELinux often uses regular expressions to specify labels that
218 match multiple files.
219 The following file types are defined for bluetooth_helper:
221 bluetooth_helper_exec_t
225 - Set files with the bluetooth_helper_exec_t type, if you want to tran‐
227 sition an executable to the bluetooth_helper_t domain.
228 bluetooth_helper_tmp_t
232 - Set files with the bluetooth_helper_tmp_t type, if you want to store
234 bluetooth helper temporary files in the /tmp directories.
235 bluetooth_helper_tmpfs_t
239 - Set files with the bluetooth_helper_tmpfs_t type, if you want to
241 store bluetooth helper files on a tmpfs file system.
242 Note: File context can be temporarily modified with the chcon command.
246 If you want to permanently change the file context you need to use the
247 semanage fcontext command. This will modify the SELinux labeling data‐
248 base. You will need to use restorecon to apply the labels.
249
252 semanage fcontext can also be used to manipulate default file context
253 mappings.
254 semanage permissive can also be used to manipulate whether or not a
256 process type is permissive.
257 semanage module can also be used to enable/disable/install/remove pol‐
259 icy modules.
260 semanage boolean can also be used to manipulate the booleans
262 system-config-selinux is a GUI tool available to customize SELinux pol‐
265 icy settings.
