6 nut_upsdrvctl_selinux - Security Enhanced Linux Policy for the nut_ups‐
7 drvctl processes
8
10 Security-Enhanced Linux secures the nut_upsdrvctl processes via flexi‐
11 ble mandatory access control.
12 The nut_upsdrvctl processes execute with the nut_upsdrvctl_t SELinux
14 type. You can check if you have these processes running by executing
15 the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep nut_upsdrvctl_t
20
24 The nut_upsdrvctl_t SELinux type can be entered via the nut_ups‐
25 drvctl_exec_t file type.
26 The default entrypoint paths for the nut_upsdrvctl_t domain are the
28 following:
29 /sbin/upsdrvctl, /usr/sbin/upsdrvctl, /usr/sbin/blazer_usb
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 nut_upsdrvctl policy is very flexible allowing users to setup their
40 nut_upsdrvctl processes in as secure a method as possible.
41 The following process types are defined for nut_upsdrvctl:
43 nut_upsdrvctl_t
45 Note: semanage permissive -a nut_upsdrvctl_t can be used to make the
47 process type nut_upsdrvctl_t permissive. SELinux does not deny access
48 to permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
53 SELinux policy is customizable based on least access required.
54 nut_upsdrvctl policy is extremely flexible and has several booleans
55 that allow you to manipulate the policy and run nut_upsdrvctl with the
56 tightest access possible.

150 must turn on the kerberos_enabled boolean. Enabled by default.
151 setsebool -P kerberos_enabled 1
153 If you want to allow system to run with NIS, you must turn on the
157 nis_enabled boolean. Disabled by default.
158 setsebool -P nis_enabled 1
160 If you want to allow confined applications to use nscd shared memory,
164 you must turn on the nscd_use_shm boolean. Disabled by default.
165 setsebool -P nscd_use_shm 1

171 The SELinux process type nut_upsdrvctl_t can manage files labeled with
172 the following file types. The paths listed are the default paths for
173 these file types. Note the processes UID still need to have DAC per‐
174 missions.

220 SELinux requires files to have an extended attribute to define the file
221 type.
222 You can see the context of a file using the -Z option to ls
224 Policy governs the access confined processes have to these files.
226 SELinux nut_upsdrvctl policy is very flexible allowing users to setup
227 their nut_upsdrvctl processes in as secure a method as possible.
228 STANDARD FILE CONTEXT
230 SELinux defines the file context types for the nut_upsdrvctl, if you
232 wanted to store files with these types in a diffent paths, you need to
233 execute the semanage command to sepecify alternate labeling and then
234 use restorecon to put the labels on disk.
235 semanage fcontext -a -t nut_upsdrvctl_tmp_t '/srv/mynut_upsdrvctl_con‐
237 tent(/.*)?'
238 restorecon -R -v /srv/mynut_upsdrvctl_content
239 Note: SELinux often uses regular expressions to specify labels that
241 match multiple files.
242 The following file types are defined for nut_upsdrvctl:
244 nut_upsdrvctl_exec_t
248 - Set files with the nut_upsdrvctl_exec_t type, if you want to transi‐
250 tion an executable to the nut_upsdrvctl_t domain.
251 Paths:
254 /sbin/upsdrvctl, /usr/sbin/upsdrvctl, /usr/sbin/blazer_usb
255 nut_upsdrvctl_tmp_t
258 - Set files with the nut_upsdrvctl_tmp_t type, if you want to store nut
260 upsdrvctl temporary files in the /tmp directories.
261 Note: File context can be temporarily modified with the chcon command.
265 If you want to permanently change the file context you need to use the
266 semanage fcontext command. This will modify the SELinux labeling data‐
267 base. You will need to use restorecon to apply the labels.
268
271 semanage fcontext can also be used to manipulate default file context
272 mappings.
273 semanage permissive can also be used to manipulate whether or not a
275 process type is permissive.
276 semanage module can also be used to enable/disable/install/remove pol‐
278 icy modules.
279 semanage boolean can also be used to manipulate the booleans
281 system-config-selinux is a GUI tool available to customize SELinux pol‐
284 icy settings.
