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 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. Disabled by
76 default.
77 setsebool -P selinuxuser_direct_dri_enabled 1
79 If you want to allows clients to write to the X server shared memory
83 segments, you must turn on the xserver_clients_write_xshm boolean. Dis‐
84 abled by default.
85 setsebool -P xserver_clients_write_xshm 1
87
91 The SELinux process type bluetooth_helper_t can manage files labeled
92 with the following file types. The paths listed are the default paths
93 for these file types. Note the processes UID still need to have DAC
94 permissions.
95 user_fonts_cache_t
97 /root/.fontconfig(/.*)?
99 /root/.fonts/auto(/.*)?
100 /root/.fonts.cache-.*
101 /root/.cache/fontconfig(/.*)?
102 /home/[^/]+/.fontconfig(/.*)?
103 /home/[^/]+/.fonts/auto(/.*)?
104 /home/[^/]+/.fonts.cache-.*
105 /home/[^/]+/.cache/fontconfig(/.*)?
106
109 SELinux requires files to have an extended attribute to define the file
110 type.
111 You can see the context of a file using the -Z option to ls
113 Policy governs the access confined processes have to these files.
115 SELinux bluetooth_helper policy is very flexible allowing users to set‐
116 up their bluetooth_helper processes in as secure a method as possible.
117 STANDARD FILE CONTEXT
119 SELinux defines the file context types for the bluetooth_helper, if you
121 wanted to store files with these types in a diffent paths, you need to
122 execute the semanage command to sepecify alternate labeling and then
123 use restorecon to put the labels on disk.
124 semanage fcontext -a -t bluetooth_helper_tmpfs_t '/srv/myblue‐
126 tooth_helper_content(/.*)?'
127 restorecon -R -v /srv/mybluetooth_helper_content
128 Note: SELinux often uses regular expressions to specify labels that
130 match multiple files.
131 The following file types are defined for bluetooth_helper:
133 bluetooth_helper_exec_t
137 - Set files with the bluetooth_helper_exec_t type, if you want to tran‐
139 sition an executable to the bluetooth_helper_t domain.
140 bluetooth_helper_tmp_t
144 - Set files with the bluetooth_helper_tmp_t type, if you want to store
146 bluetooth helper temporary files in the /tmp directories.
147 bluetooth_helper_tmpfs_t
151 - Set files with the bluetooth_helper_tmpfs_t type, if you want to
153 store bluetooth helper files on a tmpfs file system.
154 Note: File context can be temporarily modified with the chcon command.
158 If you want to permanently change the file context you need to use the
159 semanage fcontext command. This will modify the SELinux labeling data‐
160 base. You will need to use restorecon to apply the labels.
161
164 semanage fcontext can also be used to manipulate default file context
165 mappings.
166 semanage permissive can also be used to manipulate whether or not a
168 process type is permissive.
169 semanage module can also be used to enable/disable/install/remove pol‐
171 icy modules.
172 semanage boolean can also be used to manipulate the booleans
174 system-config-selinux is a GUI tool available to customize SELinux pol‐
177 icy settings.
