bluetooth_selinux(8)bluetooth SELinux Policy documentationbluetooth_selinux(8)NAMEbluetooth_selinux - Security Enhanced Linux Policy for the bluetooth
processes
DESCRIPTION
Security-Enhanced Linux secures the bluetooth processes via flexible
mandatory access control.
BOOLEANS
SELinux policy is customizable based on least access required. blue‐
tooth policy is extremely flexible and has several booleans that allow
you to manipulate the policy and run bluetooth with the tightest access
possible.
If you want to allow xguest users to use blue tooth device, you must
turn on the xguest_use_bluetooth boolean.
setsebool -P xguest_use_bluetooth 1
NSSWITCH DOMAIN
If you want to allow users to login using a sssd serve for the blue‐
tooth_t, bluetooth_helper_t, you must turn on the authlogin_nss‐
witch_use_ldap boolean.
setsebool -P authlogin_nsswitch_use_ldap 1
If you want to allow confined applications to run with kerberos for the
bluetooth_t, bluetooth_helper_t, you must turn on the allow_kerberos
boolean.
setsebool -P allow_kerberos 1
If you want to allow system to run with NI for the bluetooth_t, blue‐
tooth_helper_t, you must turn on the allow_ypbind boolean.
setsebool -P allow_ypbind 1
FILE CONTEXTS
SELinux requires files to have an extended attribute to define the file
type.
You can see the context of a file using the -Z option to ls
Policy governs the access confined processes have to these files.
SELinux bluetooth policy is very flexible allowing users to setup their
bluetooth processes in as secure a method as possible.
The following file types are defined for bluetooth:
bluetooth_conf_rw_t
- Set files with the bluetooth_conf_rw_t type, if you want to treat the
files as bluetooth conf read/write content.
bluetooth_conf_t
- Set files with the bluetooth_conf_t type, if you want to treat the
files as bluetooth configuration data, usually stored under the /etc
directory.
bluetooth_exec_t
- Set files with the bluetooth_exec_t type, if you want to transition
an executable to the bluetooth_t domain.
Paths:
/usr/sbin/hcid, /usr/bin/rfcomm, /usr/sbin/sdpd, /usr/bin/hidd,
/usr/sbin/bluetoothd, /usr/sbin/hid2hci, /usr/bin/dund,
/usr/sbin/hciattach
bluetooth_helper_exec_t
- Set files with the bluetooth_helper_exec_t type, if you want to tran‐
sition an executable to the bluetooth_helper_t domain.
bluetooth_helper_tmp_t
- Set files with the bluetooth_helper_tmp_t type, if you want to store
bluetooth helper temporary files in the /tmp directories.
bluetooth_helper_tmpfs_t
- Set files with the bluetooth_helper_tmpfs_t type, if you want to
store bluetooth helper files on a tmpfs file system.
bluetooth_initrc_exec_t
- Set files with the bluetooth_initrc_exec_t type, if you want to tran‐
sition an executable to the bluetooth_initrc_t domain.
Paths:
/etc/rc.d/init.d/dund, /etc/rc.d/init.d/bluetooth,
/etc/rc.d/init.d/pand
bluetooth_lock_t
- Set files with the bluetooth_lock_t type, if you want to treat the
files as bluetooth lock data, stored under the /var/lock directory
bluetooth_unit_file_t
- Set files with the bluetooth_unit_file_t type, if you want to treat
the files as bluetooth unit content.
bluetooth_var_lib_t
- Set files with the bluetooth_var_lib_t type, if you want to store the
bluetooth files under the /var/lib directory.
bluetooth_var_run_t
- Set files with the bluetooth_var_run_t type, if you want to store the
bluetooth files under the /run directory.
Paths:
/var/run/bluetoothd_address, /var/run/sdp
Note: File context can be temporarily modified with the chcon command.
If you want to permanantly change the file context you need to use the
semanage fcontext command. This will modify the SELinux labeling data‐
base. You will need to use restorecon to apply the labels.
PROCESS TYPES
SELinux defines process types (domains) for each process running on the
system
You can see the context of a process using the -Z option to ps
Policy governs the access confined processes have to files. SELinux
bluetooth policy is very flexible allowing users to setup their blue‐
tooth processes in as secure a method as possible.
The following process types are defined for bluetooth:
bluetooth_helper_t, bluetooth_t
Note: semanage permissive -a PROCESS_TYPE can be used to make a process
type permissive. Permissive process types are not denied access by
SELinux. AVC messages will still be generated.
COMMANDS
semanage fcontext can also be used to manipulate default file context
mappings.
semanage permissive can also be used to manipulate whether or not a
process type is permissive.
semanage module can also be used to enable/disable/install/remove pol‐
icy modules.
semanage boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux pol‐
icy settings.
