NAME

6       xenstored_selinux  -  Security  Enhanced Linux Policy for the xenstored
7       processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the xenstored  processes  via  flexible
11       mandatory access control.
12
13       The  xenstored processes execute with the xenstored_t SELinux type. You
14       can check if you have these processes running by executing the ps  com‐
15       mand with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep xenstored_t
20
21
22

ENTRYPOINTS

24       The  xenstored_t  SELinux  type can be entered via the xenstored_exec_t
25       file type.
26
27       The default entrypoint paths for the xenstored_t domain are the follow‐
28       ing:
29
30       /usr/sbin/xenstored
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       xenstored  policy  is  very flexible allowing users to setup their xen‐
40       stored processes in as secure a method as possible.
41
42       The following process types are defined for xenstored:
43
44       xenstored_t
45
46       Note: semanage permissive -a  xenstored_t  can  be  used  to  make  the
47       process  type  xenstored_t  permissive. SELinux does not deny access to
48       permissive process types, but the AVC (SELinux  denials)  messages  are
49       still generated.
50
51

BOOLEANS

53       SELinux  policy  is  customizable based on least access required.  xen‐
54       stored policy is extremely flexible and has several booleans that allow
55       you to manipulate the policy and run xenstored with the tightest access
56       possible.

MANAGED FILES

133       The SELinux process type xenstored_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.

FILE CONTEXTS

214       SELinux requires files to have an extended attribute to define the file
215       type.
216
217       You can see the context of a file using the -Z option to ls
218
219       Policy  governs  the  access  confined  processes  have to these files.
220       SELinux xenstored policy is very flexible allowing users to setup their
221       xenstored processes in as secure a method as possible.
222
223       STANDARD FILE CONTEXT
224
225       SELinux defines the file context types for the xenstored, if you wanted
226       to store files with these types in a diffent paths, you need to execute
227       the  semanage  command  to  sepecify  alternate  labeling  and then use
228       restorecon to put the labels on disk.
229
230       semanage  fcontext  -a  -t  xenstored_var_run_t  '/srv/myxenstored_con‐
231       tent(/.*)?'
232       restorecon -R -v /srv/myxenstored_content
233
234       Note:  SELinux  often  uses  regular expressions to specify labels that
235       match multiple files.
236
237       The following file types are defined for xenstored:
238
239
240
241       xenstored_exec_t
242
243       - Set files with the xenstored_exec_t type, if you want  to  transition
244       an executable to the xenstored_t domain.
245
246
247
248       xenstored_tmp_t
249
250       -  Set  files  with the xenstored_tmp_t type, if you want to store xen‐
251       stored temporary files in the /tmp directories.
252
253
254
255       xenstored_var_lib_t
256
257       - Set files with the xenstored_var_lib_t type, if you want to store the
258       xenstored files under the /var/lib directory.
259
260
261
262       xenstored_var_log_t
263
264       - Set files with the xenstored_var_log_t type, if you want to treat the
265       data as xenstored var log  data,  usually  stored  under  the  /var/log
266       directory.
267
268
269
270       xenstored_var_run_t
271
272       - Set files with the xenstored_var_run_t type, if you want to store the
273       xenstored files under the /run or /var/run directory.
274
275
276       Paths:
277            /var/run/xenstored(/.*)?, /var/run/xenstore.pid
278
279
280       Note: File context can be temporarily modified with the chcon  command.
281       If  you want to permanently change the file context you need to use the
282       semanage fcontext command.  This will modify the SELinux labeling data‐
283       base.  You will need to use restorecon to apply the labels.
284
285

COMMANDS

287       semanage  fcontext  can also be used to manipulate default file context
288       mappings.
289
290       semanage permissive can also be used to manipulate  whether  or  not  a
291       process type is permissive.
292
293       semanage  module can also be used to enable/disable/install/remove pol‐
294       icy modules.
295
296       semanage boolean can also be used to manipulate the booleans
297
298
299       system-config-selinux is a GUI tool available to customize SELinux pol‐
300       icy settings.
