6 hotplug_selinux - Security Enhanced Linux Policy for the hotplug pro‐
7 cesses
8
10 Security-Enhanced Linux secures the hotplug processes via flexible
11 mandatory access control.
12
13 The hotplug processes execute with the hotplug_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 hotplug_t
20
21
22
24 The hotplug_t SELinux type can be entered via the hotplug_etc_t, hot‐
25 plug_exec_t file types.
26
27 The default entrypoint paths for the hotplug_t domain are the follow‐
28 ing:
29
30 /etc/hotplug(/.*)?, /etc/hotplug.d/.*, /sbin/hotplug, /sbin/netplugd,
31 /etc/hotplug/firmware.agent
32
34 SELinux defines process types (domains) for each process running on the
35 system
36
37 You can see the context of a process using the -Z option to ps
38
39 Policy governs the access confined processes have to files. SELinux
40 hotplug policy is very flexible allowing users to setup their hotplug
41 processes in as secure a method as possible.
42
43 The following process types are defined for hotplug:
44
45 hotplug_t
46
47 Note: semanage permissive -a hotplug_t can be used to make the process
48 type hotplug_t permissive. SELinux does not deny access to permissive
49 process types, but the AVC (SELinux denials) messages are still gener‐
50 ated.
51
52
54 SELinux policy is customizable based on least access required. hotplug
55 policy is extremely flexible and has several booleans that allow you to
56 manipulate the policy and run hotplug with the tightest access possi‐
57 ble.

265 SELinux requires files to have an extended attribute to define the file
266 type.
267
268 You can see the context of a file using the -Z option to ls
269
270 Policy governs the access confined processes have to these files.
271 SELinux hotplug policy is very flexible allowing users to setup their
272 hotplug processes in as secure a method as possible.
273
274 STANDARD FILE CONTEXT
275
276 SELinux defines the file context types for the hotplug, if you wanted
277 to store files with these types in a diffent paths, you need to execute
278 the semanage command to sepecify alternate labeling and then use
279 restorecon to put the labels on disk.
280
281 semanage fcontext -a -t hotplug_var_run_t '/srv/myhotplug_con‐
282 tent(/.*)?'
283 restorecon -R -v /srv/myhotplug_content
284
285 Note: SELinux often uses regular expressions to specify labels that
286 match multiple files.
287
288 The following file types are defined for hotplug:
289
290
291
292 hotplug_etc_t
293
294 - Set files with the hotplug_etc_t type, if you want to store hotplug
295 files in the /etc directories.
296
297
298
299 hotplug_exec_t
300
301 - Set files with the hotplug_exec_t type, if you want to transition an
302 executable to the hotplug_t domain.
303
304
305 Paths:
306 /etc/hotplug.d/.*, /sbin/hotplug, /sbin/netplugd, /etc/hot‐
307 plug/firmware.agent
308
309
310 hotplug_var_run_t
311
312 - Set files with the hotplug_var_run_t type, if you want to store the
313 hotplug files under the /run or /var/run directory.
314
315
316 Paths:
317 /var/run/usb(/.*)?, /var/run/hotplug(/.*)?
318
319
320 Note: File context can be temporarily modified with the chcon command.
321 If you want to permanently change the file context you need to use the
322 semanage fcontext command. This will modify the SELinux labeling data‐
323 base. You will need to use restorecon to apply the labels.
324
325
327 semanage fcontext can also be used to manipulate default file context
328 mappings.
329
330 semanage permissive can also be used to manipulate whether or not a
331 process type is permissive.
332
333 semanage module can also be used to enable/disable/install/remove pol‐
334 icy modules.
335
336 semanage boolean can also be used to manipulate the booleans
337
338
339 system-config-selinux is a GUI tool available to customize SELinux pol‐
340 icy settings.
