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
58
59
60 If you want to allow all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62
63 setsebool -P fips_mode 1
64
65
66
67 If you want to allow system to run with NIS, you must turn on the
68 nis_enabled boolean. Disabled by default.
69
70 setsebool -P nis_enabled 1
71
72
73
75 The SELinux process type sensord_t can manage files labeled with the
76 following file types. The paths listed are the default paths for these
77 file types. Note the processes UID still need to have DAC permissions.

124 SELinux requires files to have an extended attribute to define the file
125 type.
126
127 You can see the context of a file using the -Z option to ls
128
129 Policy governs the access confined processes have to these files.
130 SELinux sensord policy is very flexible allowing users to setup their
131 sensord processes in as secure a method as possible.
132
133 STANDARD FILE CONTEXT
134
135 SELinux defines the file context types for the sensord, if you wanted
136 to store files with these types in a diffent paths, you need to execute
137 the semanage command to sepecify alternate labeling and then use
138 restorecon to put the labels on disk.
139
140 semanage fcontext -a -t sensord_log_t '/srv/mysensord_content(/.*)?'
141 restorecon -R -v /srv/mysensord_content
142
143 Note: SELinux often uses regular expressions to specify labels that
144 match multiple files.
145
146 The following file types are defined for sensord:
147
148
149
150 sensord_exec_t
151
152 - Set files with the sensord_exec_t type, if you want to transition an
153 executable to the sensord_t domain.
154
155
156 Paths:
157 /usr/sbin/sensord, /usr/libexec/lm_sensors/sensord-service-wrapper
158
159
160 sensord_initrc_exec_t
161
162 - Set files with the sensord_initrc_exec_t type, if you want to transi‐
163 tion an executable to the sensord_initrc_t domain.
164
165
166
167 sensord_log_t
168
169 - Set files with the sensord_log_t type, if you want to treat the data
170 as sensord log data, usually stored under the /var/log directory.
171
172
173
174 sensord_unit_file_t
175
176 - Set files with the sensord_unit_file_t type, if you want to treat the
177 files as sensord unit content.
178
179
180
181 sensord_var_run_t
182
183 - Set files with the sensord_var_run_t type, if you want to store the
184 sensord files under the /run or /var/run directory.
185
186
187
188 Note: File context can be temporarily modified with the chcon command.
189 If you want to permanently change the file context you need to use the
190 semanage fcontext command. This will modify the SELinux labeling data‐
191 base. You will need to use restorecon to apply the labels.
192
193
195 semanage fcontext can also be used to manipulate default file context
196 mappings.
197
198 semanage permissive can also be used to manipulate whether or not a
199 process type is permissive.
200
201 semanage module can also be used to enable/disable/install/remove pol‐
202 icy modules.
203
204 semanage boolean can also be used to manipulate the booleans
205
206
207 system-config-selinux is a GUI tool available to customize SELinux pol‐
208 icy settings.
