6 vdagent_selinux - Security Enhanced Linux Policy for the vdagent pro‐
7 cesses
8
10 Security-Enhanced Linux secures the vdagent processes via flexible
11 mandatory access control.
12
13 The vdagent processes execute with the vdagent_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 vdagent_t
20
21
22
24 The vdagent_t SELinux type can be entered via the vdagent_exec_t file
25 type.
26
27 The default entrypoint paths for the vdagent_t domain are the follow‐
28 ing:
29
30 /sbin/vdagent, /usr/sbin/spice-vdagentd
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 vdagent policy is very flexible allowing users to setup their vdagent
40 processes in as secure a method as possible.
41
42 The following process types are defined for vdagent:
43
44 vdagent_t
45
46 Note: semanage permissive -a vdagent_t can be used to make the process
47 type vdagent_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. vdagent
54 policy is extremely flexible and has several booleans that allow you to
55 manipulate the policy and run vdagent with the tightest access possi‐
56 ble.

133 The SELinux process type vdagent_t can manage files labeled with the
134 following file types. The paths listed are the default paths for these
135 file types. Note the processes UID still need to have DAC permissions.

206 SELinux requires files to have an extended attribute to define the file
207 type.
208
209 You can see the context of a file using the -Z option to ls
210
211 Policy governs the access confined processes have to these files.
212 SELinux vdagent policy is very flexible allowing users to setup their
213 vdagent processes in as secure a method as possible.
214
215 EQUIVALENCE DIRECTORIES
216
217
218 vdagent policy stores data with multiple different file context types
219 under the /var/run/spice-vdagentd directory. If you would like to
220 store the data in a different directory you can use the semanage com‐
221 mand to create an equivalence mapping. If you wanted to store this
222 data under the /srv dirctory you would execute the following command:
223
224 semanage fcontext -a -e /var/run/spice-vdagentd /srv/spice-vdagentd
225 restorecon -R -v /srv/spice-vdagentd
226
227 vdagent policy stores data with multiple different file context types
228 under the /var/log/spice-vdagentd directory. If you would like to
229 store the data in a different directory you can use the semanage com‐
230 mand to create an equivalence mapping. If you wanted to store this
231 data under the /srv dirctory you would execute the following command:
232
233 semanage fcontext -a -e /var/log/spice-vdagentd /srv/spice-vdagentd
234 restorecon -R -v /srv/spice-vdagentd
235
236 STANDARD FILE CONTEXT
237
238 SELinux defines the file context types for the vdagent, if you wanted
239 to store files with these types in a diffent paths, you need to execute
240 the semanage command to sepecify alternate labeling and then use
241 restorecon to put the labels on disk.
242
243 semanage fcontext -a -t vdagent_var_run_t '/srv/myvdagent_con‐
244 tent(/.*)?'
245 restorecon -R -v /srv/myvdagent_content
246
247 Note: SELinux often uses regular expressions to specify labels that
248 match multiple files.
249
250 The following file types are defined for vdagent:
251
252
253
254 vdagent_exec_t
255
256 - Set files with the vdagent_exec_t type, if you want to transition an
257 executable to the vdagent_t domain.
258
259
260 Paths:
261 /sbin/vdagent, /usr/sbin/spice-vdagentd
262
263
264 vdagent_log_t
265
266 - Set files with the vdagent_log_t type, if you want to treat the data
267 as vdagent log data, usually stored under the /var/log directory.
268
269
270 Paths:
271 /var/log/spice-vdagentd(/.*)?, /var/log/spice-vdagentd.log.*
272
273
274 vdagent_var_run_t
275
276 - Set files with the vdagent_var_run_t type, if you want to store the
277 vdagent files under the /run or /var/run directory.
278
279
280 Paths:
281 /var/run/spice-vdagentd(/.*)?, /var/run/spice-vdagentd.pid
282
283
284 Note: File context can be temporarily modified with the chcon command.
285 If you want to permanently change the file context you need to use the
286 semanage fcontext command. This will modify the SELinux labeling data‐
287 base. You will need to use restorecon to apply the labels.
288
289
291 semanage fcontext can also be used to manipulate default file context
292 mappings.
293
294 semanage permissive can also be used to manipulate whether or not a
295 process type is permissive.
296
297 semanage module can also be used to enable/disable/install/remove pol‐
298 icy modules.
299
300 semanage boolean can also be used to manipulate the booleans
301
302
303 system-config-selinux is a GUI tool available to customize SELinux pol‐
304 icy settings.
