NAME

6       vdagent_selinux  -  Security Enhanced Linux Policy for the vdagent pro‐
7       cesses
8

DESCRIPTION

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

ENTRYPOINTS

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       /usr/sbin/spice-vdagentd
31

PROCESS TYPES

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

BOOLEANS

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.
57

104       If you want to allow all domains write to kmsg_device, while kernel  is

MANAGED FILES

142       The  SELinux  process  type vdagent_t can manage files labeled with the
143       following file types.  The paths listed are the default paths for these
144       file types.  Note the processes UID still need to have DAC permissions.
145
146       cluster_conf_t

FILE CONTEXTS

192       SELinux requires files to have an extended attribute to define the file
193       type.
194
195       You can see the context of a file using the -Z option to ls
196
197       Policy governs the access  confined  processes  have  to  these  files.
198       SELinux  vdagent  policy is very flexible allowing users to setup their
199       vdagent processes in as secure a method as possible.
200
201       EQUIVALENCE DIRECTORIES
202
203
204       vdagent policy stores data with multiple different file  context  types
205       under  the  /var/run/spice-vdagentd  directory.   If  you would like to
206       store the data in a different directory you can use the  semanage  com‐
207       mand  to  create  an  equivalence mapping.  If you wanted to store this
208       data under the /srv dirctory you would execute the following command:
209
210       semanage fcontext -a -e /var/run/spice-vdagentd /srv/spice-vdagentd
211       restorecon -R -v /srv/spice-vdagentd
212
213       vdagent policy stores data with multiple different file  context  types
214       under  the  /var/log/spice-vdagentd  directory.   If  you would like to
215       store the data in a different directory you can use the  semanage  com‐
216       mand  to  create  an  equivalence mapping.  If you wanted to store this
217       data under the /srv dirctory you would execute the following command:
218
219       semanage fcontext -a -e /var/log/spice-vdagentd /srv/spice-vdagentd
220       restorecon -R -v /srv/spice-vdagentd
221
222       STANDARD FILE CONTEXT
223
224       SELinux defines the file context types for the vdagent, if  you  wanted
225       to store files with these types in a diffent paths, you need to execute
226       the semanage command  to  sepecify  alternate  labeling  and  then  use
227       restorecon to put the labels on disk.
228
229       semanage   fcontext   -a   -t   vdagent_var_run_t  '/srv/myvdagent_con‐
230       tent(/.*)?'
231       restorecon -R -v /srv/myvdagent_content
232
233       Note: SELinux often uses regular expressions  to  specify  labels  that
234       match multiple files.
235
236       The following file types are defined for vdagent:
237
238
239
240       vdagent_exec_t
241
242       -  Set files with the vdagent_exec_t type, if you want to transition an
243       executable to the vdagent_t domain.
244
245
246
247       vdagent_log_t
248
249       - Set files with the vdagent_log_t type, if you want to treat the  data
250       as vdagent log data, usually stored under the /var/log directory.
251
252
253       Paths:
254            /var/log/spice-vdagentd(/.*)?, /var/log/spice-vdagentd.log.*
255
256
257       vdagent_var_run_t
258
259       -  Set  files with the vdagent_var_run_t type, if you want to store the
260       vdagent files under the /run or /var/run directory.
261
262
263       Paths:
264            /var/run/spice-vdagentd(/.*)?, /var/run/spice-vdagentd.pid
265
266
267       vdagentd_initrc_exec_t
268
269       - Set files with the vdagentd_initrc_exec_t type, if you want to  tran‐
270       sition an executable to the vdagentd_initrc_t domain.
271
272
273
274       Note:  File context can be temporarily modified with the chcon command.
275       If you want to permanently change the file context you need to use  the
276       semanage fcontext command.  This will modify the SELinux labeling data‐
277       base.  You will need to use restorecon to apply the labels.
278
279

COMMANDS

281       semanage fcontext can also be used to manipulate default  file  context
282       mappings.
283
284       semanage  permissive  can  also  be used to manipulate whether or not a
285       process type is permissive.
286
287       semanage module can also be used to enable/disable/install/remove  pol‐
288       icy modules.
289
290       semanage boolean can also be used to manipulate the booleans
291
292
293       system-config-selinux is a GUI tool available to customize SELinux pol‐
294       icy settings.
