6 rhev_agentd_selinux - Security Enhanced Linux Policy for the
7 rhev_agentd processes
8
10 Security-Enhanced Linux secures the rhev_agentd processes via flexible
11 mandatory access control.
12
13 The rhev_agentd processes execute with the rhev_agentd_t SELinux type.
14 You can check if you have these processes running by executing the ps
15 command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep rhev_agentd_t
20
21
22
24 The rhev_agentd_t SELinux type can be entered via the
25 rhev_agentd_exec_t file type.
26
27 The default entrypoint paths for the rhev_agentd_t domain are the fol‐
28 lowing:
29
30 /usr/share/ovirt-guest-agent, /usr/share/rhev-agent/rhev-agentd.py,
31 /usr/share/rhev-agent/LockActiveSession.py, /usr/share/ovirt-guest-
32 agent/LockActiveSession.py
33
35 SELinux defines process types (domains) for each process running on the
36 system
37
38 You can see the context of a process using the -Z option to ps
39
40 Policy governs the access confined processes have to files. SELinux
41 rhev_agentd policy is very flexible allowing users to setup their
42 rhev_agentd processes in as secure a method as possible.
43
44 The following process types are defined for rhev_agentd:
45
46 rhev_agentd_t, rhev_agentd_consolehelper_t
47
48 Note: semanage permissive -a rhev_agentd_t can be used to make the
49 process type rhev_agentd_t permissive. SELinux does not deny access to
50 permissive process types, but the AVC (SELinux denials) messages are
51 still generated.
52
53
55 SELinux policy is customizable based on least access required.
56 rhev_agentd policy is extremely flexible and has several booleans that
57 allow you to manipulate the policy and run rhev_agentd with the tight‐
58 est access possible.

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

228 SELinux requires files to have an extended attribute to define the file
229 type.
230
231 You can see the context of a file using the -Z option to ls
232
233 Policy governs the access confined processes have to these files.
234 SELinux rhev_agentd policy is very flexible allowing users to setup
235 their rhev_agentd processes in as secure a method as possible.
236
237 STANDARD FILE CONTEXT
238
239 SELinux defines the file context types for the rhev_agentd, if you
240 wanted to store files with these types in a diffent paths, you need to
241 execute the semanage command to sepecify alternate labeling and then
242 use restorecon to put the labels on disk.
243
244 semanage fcontext -a -t rhev_agentd_var_run_t '/srv/myrhev_agentd_con‐
245 tent(/.*)?'
246 restorecon -R -v /srv/myrhev_agentd_content
247
248 Note: SELinux often uses regular expressions to specify labels that
249 match multiple files.
250
251 The following file types are defined for rhev_agentd:
252
253
254
255 rhev_agentd_exec_t
256
257 - Set files with the rhev_agentd_exec_t type, if you want to transition
258 an executable to the rhev_agentd_t domain.
259
260
261 Paths:
262 /usr/share/ovirt-guest-agent, /usr/share/rhev-agent/rhev-
263 agentd.py, /usr/share/rhev-agent/LockActiveSession.py,
264 /usr/share/ovirt-guest-agent/LockActiveSession.py
265
266
267 rhev_agentd_log_t
268
269 - Set files with the rhev_agentd_log_t type, if you want to treat the
270 data as rhev agentd log data, usually stored under the /var/log direc‐
271 tory.
272
273
274 Paths:
275 /var/log/rhev-agent(/.*)?, /var/log/ovirt-guest-agent(/.*)?
276
277
278 rhev_agentd_tmp_t
279
280 - Set files with the rhev_agentd_tmp_t type, if you want to store rhev
281 agentd temporary files in the /tmp directories.
282
283
284
285 rhev_agentd_unit_file_t
286
287 - Set files with the rhev_agentd_unit_file_t type, if you want to treat
288 the files as rhev agentd unit content.
289
290
291
292 rhev_agentd_var_run_t
293
294 - Set files with the rhev_agentd_var_run_t type, if you want to store
295 the rhev agentd files under the /run or /var/run directory.
296
297
298 Paths:
299 /var/run/rhev-agentd.pid, /var/run/ovirt-guest-agent.pid
300
301
302 Note: File context can be temporarily modified with the chcon command.
303 If you want to permanently change the file context you need to use the
304 semanage fcontext command. This will modify the SELinux labeling data‐
305 base. You will need to use restorecon to apply the labels.
306
307
309 semanage fcontext can also be used to manipulate default file context
310 mappings.
311
312 semanage permissive can also be used to manipulate whether or not a
313 process type is permissive.
314
315 semanage module can also be used to enable/disable/install/remove pol‐
316 icy modules.
317
318 semanage boolean can also be used to manipulate the booleans
319
320
321 system-config-selinux is a GUI tool available to customize SELinux pol‐
322 icy settings.
