6 sensord_selinux - Security Enhanced Linux Policy for the sensord pro‐
7 cesses
8
10 Security-Enhanced Linux secures the sensord processes via flexible
11 mandatory access control.
12
13 The sensord processes execute with the sensord_t SELinux type. You can
14 check if you have these processes running by executing the ps command
15 with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep sensord_t
20
21
22
24 The sensord_t SELinux type can be entered via the sensord_exec_t file
25 type.
26
27 The default entrypoint paths for the sensord_t domain are the follow‐
28 ing:
29
30 /usr/sbin/sensord, /usr/libexec/lm_sensors/sensord-service-wrapper
31
33 SELinux defines process types (domains) for each process running on the
34 system
35
36 You can see the context of a process using the -Z option to ps
37
38 Policy governs the access confined processes have to files. SELinux
39 sensord policy is very flexible allowing users to setup their sensord
40 processes in as secure a method as possible.
41
42 The following process types are defined for sensord:
43
44 sensord_t
45
46 Note: semanage permissive -a sensord_t can be used to make the process
47 type sensord_t permissive. SELinux does not deny access to permissive
48 process types, but the AVC (SELinux denials) messages are still gener‐
49 ated.
50
51
53 SELinux policy is customizable based on least access required. sensord
54 policy is extremely flexible and has several booleans that allow you to
55 manipulate the policy and run sensord with the tightest access possi‐
56 ble.
57

59
60 If you want to allow users to resolve user passwd entries directly from
61 ldap rather then using a sssd server, you must turn on the authlo‐
62 gin_nsswitch_use_ldap boolean. Disabled by default.
63
64 setsebool -P authlogin_nsswitch_use_ldap 1
65
66
67
68 If you want to allow all domains to execute in fips_mode, you must turn
69 on the fips_mode boolean. Enabled by default.
70
71 setsebool -P fips_mode 1
72
73
74
75 If you want to allow confined applications to run with kerberos, you
76 must turn on the kerberos_enabled boolean. Disabled by default.
77
78 setsebool -P kerberos_enabled 1
79
80
81
82 If you want to allow system to run with NIS, you must turn on the
83 nis_enabled boolean. Disabled by default.
84
85 setsebool -P nis_enabled 1
86
87
88
89 If you want to allow confined applications to use nscd shared memory,
90 you must turn on the nscd_use_shm boolean. Disabled by default.
91
92 setsebool -P nscd_use_shm 1
93
94
95
97 The SELinux process type sensord_t can manage files labeled with the
98 following file types. The paths listed are the default paths for these
99 file types. Note the processes UID still need to have DAC permissions.

146 SELinux requires files to have an extended attribute to define the file
147 type.
148
149 You can see the context of a file using the -Z option to ls
150
151 Policy governs the access confined processes have to these files.
152 SELinux sensord policy is very flexible allowing users to setup their
153 sensord processes in as secure a method as possible.
154
155 STANDARD FILE CONTEXT
156
157 SELinux defines the file context types for the sensord, if you wanted
158 to store files with these types in a diffent paths, you need to execute
159 the semanage command to sepecify alternate labeling and then use
160 restorecon to put the labels on disk.
161
162 semanage fcontext -a -t sensord_log_t '/srv/mysensord_content(/.*)?'
163 restorecon -R -v /srv/mysensord_content
164
165 Note: SELinux often uses regular expressions to specify labels that
166 match multiple files.
167
168 The following file types are defined for sensord:
169
170
171
172 sensord_exec_t
173
174 - Set files with the sensord_exec_t type, if you want to transition an
175 executable to the sensord_t domain.
176
177
178 Paths:
179 /usr/sbin/sensord, /usr/libexec/lm_sensors/sensord-service-wrapper
180
181
182 sensord_initrc_exec_t
183
184 - Set files with the sensord_initrc_exec_t type, if you want to transi‐
185 tion an executable to the sensord_initrc_t domain.
186
187
188
189 sensord_log_t
190
191 - Set files with the sensord_log_t type, if you want to treat the data
192 as sensord log data, usually stored under the /var/log directory.
193
194
195
196 sensord_unit_file_t
197
198 - Set files with the sensord_unit_file_t type, if you want to treat the
199 files as sensord unit content.
200
201
202
203 sensord_var_run_t
204
205 - Set files with the sensord_var_run_t type, if you want to store the
206 sensord files under the /run or /var/run directory.
207
208
209
210 Note: File context can be temporarily modified with the chcon command.
211 If you want to permanently change the file context you need to use the
212 semanage fcontext command. This will modify the SELinux labeling data‐
213 base. You will need to use restorecon to apply the labels.
214
215
217 semanage fcontext can also be used to manipulate default file context
218 mappings.
219
220 semanage permissive can also be used to manipulate whether or not a
221 process type is permissive.
222
223 semanage module can also be used to enable/disable/install/remove pol‐
224 icy modules.
225
226 semanage boolean can also be used to manipulate the booleans
227
228
229 system-config-selinux is a GUI tool available to customize SELinux pol‐
230 icy settings.
