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
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
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
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
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
54
55
56 If you want to allow users to resolve user passwd entries directly from
57 ldap rather then using a sssd server, you must turn on the authlo‐
58 gin_nsswitch_use_ldap boolean. Disabled by default.
59
60 setsebool -P authlogin_nsswitch_use_ldap 1
61
62
63
64 If you want to allow all domains to execute in fips_mode, you must turn
65 on the fips_mode boolean. Enabled by default.
66
67 setsebool -P fips_mode 1
68
69
70
71 If you want to allow confined applications to run with kerberos, you
72 must turn on the kerberos_enabled boolean. Enabled by default.
73
74 setsebool -P kerberos_enabled 1
75
76
77
78 If you want to allow system to run with NIS, you must turn on the
79 nis_enabled boolean. Disabled by default.
80
81 setsebool -P nis_enabled 1
82
83
84
85 If you want to allow confined applications to use nscd shared memory,
86 you must turn on the nscd_use_shm boolean. Enabled by default.
87
88 setsebool -P nscd_use_shm 1
89

91
93 SELinux defines port types to represent TCP and UDP ports.
94
95 You can see the types associated with a port by using the following
96 command:
97
98 semanage port -l
99
100
101 Policy governs the access confined processes have to these ports.
102 SELinux gpsd policy is very flexible allowing users to setup their gpsd
103 processes in as secure a method as possible.
104
105 The following port types are defined for gpsd:
106
107
108 gpsd_port_t
109
110
111
112 Default Defined Ports:
113 tcp 2947
114
116 The SELinux process type gpsd_t can manage files labeled with the fol‐
117 lowing file types. The paths listed are the default paths for these
118 file types. Note the processes UID still need to have DAC permissions.

171 SELinux requires files to have an extended attribute to define the file
172 type.
173
174 You can see the context of a file using the -Z option to ls
175
176 Policy governs the access confined processes have to these files.
177 SELinux gpsd policy is very flexible allowing users to setup their gpsd
178 processes in as secure a method as possible.
179
180 STANDARD FILE CONTEXT
181
182 SELinux defines the file context types for the gpsd, if you wanted to
183 store files with these types in a diffent paths, you need to execute
184 the semanage command to sepecify alternate labeling and then use
185 restorecon to put the labels on disk.
186
187 semanage fcontext -a -t gpsd_var_run_t '/srv/mygpsd_content(/.*)?'
188 restorecon -R -v /srv/mygpsd_content
189
190 Note: SELinux often uses regular expressions to specify labels that
191 match multiple files.
192
193 The following file types are defined for gpsd:
194
195
196
197 gpsd_exec_t
198
199 - Set files with the gpsd_exec_t type, if you want to transition an
200 executable to the gpsd_t domain.
201
202
203
204 gpsd_initrc_exec_t
205
206 - Set files with the gpsd_initrc_exec_t type, if you want to transition
207 an executable to the gpsd_initrc_t domain.
208
209
210
211 gpsd_tmpfs_t
212
213 - Set files with the gpsd_tmpfs_t type, if you want to store gpsd files
214 on a tmpfs file system.
215
216
217
218 gpsd_var_run_t
219
220 - Set files with the gpsd_var_run_t type, if you want to store the gpsd
221 files under the /run or /var/run directory.
222
223
224 Paths:
225 /var/run/gpsd.pid, /var/run/gpsd.sock
226
227
228 Note: File context can be temporarily modified with the chcon command.
229 If you want to permanently change the file context you need to use the
230 semanage fcontext command. This will modify the SELinux labeling data‐
231 base. You will need to use restorecon to apply the labels.
232
233
235 semanage fcontext can also be used to manipulate default file context
236 mappings.
237
238 semanage permissive can also be used to manipulate whether or not a
239 process type is permissive.
240
241 semanage module can also be used to enable/disable/install/remove pol‐
242 icy modules.
243
244 semanage port can also be used to manipulate the port definitions
245
246 semanage boolean can also be used to manipulate the booleans
247
248
249 system-config-selinux is a GUI tool available to customize SELinux pol‐
250 icy settings.
