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 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 For example:
18 ps -eZ | grep sensord_t
20
24 The sensord_t SELinux type can be entered via the sensord_exec_t file
25 type.
26 The default entrypoint paths for the sensord_t domain are the follow‐
28 ing:
29 /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 You can see the context of a process using the -Z option to ps
37 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 The following process types are defined for sensord:
43 sensord_t
45 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
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 If you want to dontaudit all daemons scheduling requests (setsched,
61 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
62 Enabled by default.
63 setsebool -P daemons_dontaudit_scheduling 1
65 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 setsebool -P fips_mode 1
72 If you want to allow system to run with NIS, you must turn on the
76 nis_enabled boolean. Disabled by default.
77 setsebool -P nis_enabled 1
79
83 The SELinux process type sensord_t can manage files labeled with the
84 following file types. The paths listed are the default paths for these
85 file types. Note the processes UID still need to have DAC permissions.

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