NAME

6       gpsd_selinux - Security Enhanced Linux Policy for the gpsd processes
7

DESCRIPTION

9       Security-Enhanced  Linux secures the gpsd processes via flexible manda‐
10       tory access control.
11
12       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
16       For example:
17
18       ps -eZ | grep gpsd_t
19
20
21

ENTRYPOINTS

23       The gpsd_t SELinux type can be entered via the gpsd_exec_t file type.
24
25       The default entrypoint paths for the gpsd_t domain are the following:
26
27       /usr/sbin/gpsd
28

PROCESS TYPES

30       SELinux defines process types (domains) for each process running on the
31       system
32
33       You can see the context of a process using the -Z option to ps
34
35       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
39       The following process types are defined for gpsd:
40
41       gpsd_t
42
43       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
48

BOOLEANS

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.

PORT TYPES

167       SELinux defines port types to represent TCP and UDP ports.
168
169       You can see the types associated with a port  by  using  the  following
170       command:
171
172       semanage port -l
173
174
175       Policy  governs  the  access  confined  processes  have to these ports.
176       SELinux gpsd policy is very flexible allowing users to setup their gpsd
177       processes in as secure a method as possible.
178
179       The following port types are defined for gpsd:
180
181
182       gpsd_port_t
183
184
185
186       Default Defined Ports:
187                 tcp 2947
188

MANAGED FILES

190       The  SELinux process type gpsd_t can manage files labeled with the fol‐
191       lowing file types.  The paths listed are the default  paths  for  these
192       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

245       SELinux requires files to have an extended attribute to define the file
246       type.
247
248       You can see the context of a file using the -Z option to ls
249
250       Policy governs the access  confined  processes  have  to  these  files.
251       SELinux gpsd policy is very flexible allowing users to setup their gpsd
252       processes in as secure a method as possible.
253
254       STANDARD FILE CONTEXT
255
256       SELinux defines the file context types for the gpsd, if you  wanted  to
257       store  files  with  these types in a diffent paths, you need to execute
258       the semanage command  to  sepecify  alternate  labeling  and  then  use
259       restorecon to put the labels on disk.
260
261       semanage fcontext -a -t gpsd_var_run_t '/srv/mygpsd_content(/.*)?'
262       restorecon -R -v /srv/mygpsd_content
263
264       Note:  SELinux  often  uses  regular expressions to specify labels that
265       match multiple files.
266
267       The following file types are defined for gpsd:
268
269
270
271       gpsd_exec_t
272
273       - Set files with the gpsd_exec_t type, if you  want  to  transition  an
274       executable to the gpsd_t domain.
275
276
277
278       gpsd_initrc_exec_t
279
280       - Set files with the gpsd_initrc_exec_t type, if you want to transition
281       an executable to the gpsd_initrc_t domain.
282
283
284
285       gpsd_tmpfs_t
286
287       - Set files with the gpsd_tmpfs_t type, if you want to store gpsd files
288       on a tmpfs file system.
289
290
291
292       gpsd_var_run_t
293
294       - Set files with the gpsd_var_run_t type, if you want to store the gpsd
295       files under the /run or /var/run directory.
296
297
298       Paths:
299            /var/run/gpsd.pid, /var/run/gpsd.sock
300
301
302       Note: File context can be temporarily modified with the chcon  command.
303       If  you want to permanently change the file context you need to use the
304       semanage fcontext command.  This will modify the SELinux labeling data‐
305       base.  You will need to use restorecon to apply the labels.
306
307

COMMANDS

309       semanage  fcontext  can also be used to manipulate default file context
310       mappings.
311
312       semanage permissive can also be used to manipulate  whether  or  not  a
313       process type is permissive.
314
315       semanage  module can also be used to enable/disable/install/remove pol‐
316       icy modules.
317
318       semanage port can also be used to manipulate the port definitions
319
320       semanage boolean can also be used to manipulate the booleans
321
322
323       system-config-selinux is a GUI tool available to customize SELinux pol‐
324       icy settings.
