6 gpsd_selinux - Security Enhanced Linux Policy for the gpsd processes
7
9 Security-Enhanced Linux secures the gpsd processes via flexible manda‐
10 tory access control.
11 The gpsd processes execute with the gpsd_t SELinux type. You can check
13 if you have these processes running by executing the ps command with
14 the -Z qualifier.
15 For example:
17 ps -eZ | grep gpsd_t
19
23 The gpsd_t SELinux type can be entered via the gpsd_exec_t file type.
24 The default entrypoint paths for the gpsd_t domain are the following:
26 /usr/sbin/gpsd
28
30 SELinux defines process types (domains) for each process running on the
31 system
32 You can see the context of a process using the -Z option to ps
34 Policy governs the access confined processes have to files. SELinux
36 gpsd policy is very flexible allowing users to setup their gpsd pro‐
37 cesses in as secure a method as possible.
38 The following process types are defined for gpsd:
40 gpsd_t
42 Note: semanage permissive -a gpsd_t can be used to make the process
44 type gpsd_t permissive. SELinux does not deny access to permissive
45 process types, but the AVC (SELinux denials) messages are still gener‐
46 ated.
47
50 SELinux policy is customizable based on least access required. gpsd
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run gpsd with the tightest access possible.
53 If you want to allow all daemons to write corefiles to /, you must turn
57 on the allow_daemons_dump_core boolean. Disabled by default.

143 you must turn on the nscd_use_shm boolean. Enabled by default.
144 setsebool -P nscd_use_shm 1
146
150 SELinux defines port types to represent TCP and UDP ports.
151 You can see the types associated with a port by using the following
153 command:
154 semanage port -l
156 Policy governs the access confined processes have to these ports.
159 SELinux gpsd policy is very flexible allowing users to setup their gpsd
160 processes in as secure a method as possible.
161 The following port types are defined for gpsd:
163 gpsd_port_t
166 Default Defined Ports:
170 tcp 2947
171
173 The SELinux process type gpsd_t can manage files labeled with the fol‐
174 lowing file types. The paths listed are the default paths for these
175 file types. Note the processes UID still need to have DAC permissions.

250 SELinux requires files to have an extended attribute to define the file
251 type.
252 You can see the context of a file using the -Z option to ls
254 Policy governs the access confined processes have to these files.
256 SELinux gpsd policy is very flexible allowing users to setup their gpsd
257 processes in as secure a method as possible.
258 STANDARD FILE CONTEXT
260 SELinux defines the file context types for the gpsd, if you wanted to
262 store files with these types in a diffent paths, you need to execute
263 the semanage command to sepecify alternate labeling and then use
264 restorecon to put the labels on disk.
265 semanage fcontext -a -t gpsd_var_run_t '/srv/mygpsd_content(/.*)?'
267 restorecon -R -v /srv/mygpsd_content
268 Note: SELinux often uses regular expressions to specify labels that
270 match multiple files.
271 The following file types are defined for gpsd:
273 gpsd_exec_t
277 - Set files with the gpsd_exec_t type, if you want to transition an
279 executable to the gpsd_t domain.
280 gpsd_initrc_exec_t
284 - Set files with the gpsd_initrc_exec_t type, if you want to transition
286 an executable to the gpsd_initrc_t domain.
287 gpsd_tmpfs_t
291 - Set files with the gpsd_tmpfs_t type, if you want to store gpsd files
293 on a tmpfs file system.
294 gpsd_var_run_t
298 - Set files with the gpsd_var_run_t type, if you want to store the gpsd
300 files under the /run or /var/run directory.
301 Paths:
304 /var/run/gpsd.pid, /var/run/gpsd.sock
305 Note: File context can be temporarily modified with the chcon command.
308 If you want to permanently change the file context you need to use the
309 semanage fcontext command. This will modify the SELinux labeling data‐
310 base. You will need to use restorecon to apply the labels.
311
314 semanage fcontext can also be used to manipulate default file context
315 mappings.
316 semanage permissive can also be used to manipulate whether or not a
318 process type is permissive.
319 semanage module can also be used to enable/disable/install/remove pol‐
321 icy modules.
322 semanage port can also be used to manipulate the port definitions
324 semanage boolean can also be used to manipulate the booleans
326 system-config-selinux is a GUI tool available to customize SELinux pol‐
329 icy settings.
