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, /usr/sbin/oxenstored
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.
57
58
59
60       If you want to allow all daemons to write corefiles to /, you must turn
61       on the daemons_dump_core boolean. Disabled by default.

85
86
87
88       If you want to deny any process from ptracing or  debugging  any  other
89       processes,  you  must  turn  on  the  deny_ptrace  boolean.  Enabled by
90       default.
91
92       setsebool -P deny_ptrace 1
93
94
95
96       If you want to allow any process  to  mmap  any  file  on  system  with
97       attribute  file_type,  you must turn on the domain_can_mmap_files bool‐
98       ean. Enabled by default.

MANAGED FILES

142       The  SELinux process type xenstored_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.

FILE CONTEXTS

202       SELinux requires files to have an extended attribute to define the file
203       type.
204
205       You can see the context of a file using the -Z option to ls
206
207       Policy governs the access  confined  processes  have  to  these  files.
208       SELinux xenstored policy is very flexible allowing users to setup their
209       xenstored processes in as secure a method as possible.
210
211       STANDARD FILE CONTEXT
212
213       SELinux defines the file context types for the xenstored, if you wanted
214       to store files with these types in a diffent paths, you need to execute
215       the semanage command  to  sepecify  alternate  labeling  and  then  use
216       restorecon to put the labels on disk.
217
218       semanage  fcontext  -a  -t  xenstored_var_run_t  '/srv/myxenstored_con‐
219       tent(/.*)?'
220       restorecon -R -v /srv/myxenstored_content
221
222       Note: SELinux often uses regular expressions  to  specify  labels  that
223       match multiple files.
224
225       The following file types are defined for xenstored:
226
227
228
229       xenstored_exec_t
230
231       -  Set  files with the xenstored_exec_t type, if you want to transition
232       an executable to the xenstored_t domain.
233
234
235       Paths:
236            /usr/sbin/xenstored, /usr/sbin/oxenstored
237
238
239       xenstored_tmp_t
240
241       - Set files with the xenstored_tmp_t type, if you want  to  store  xen‐
242       stored temporary files in the /tmp directories.
243
244
245
246       xenstored_var_lib_t
247
248       - Set files with the xenstored_var_lib_t type, if you want to store the
249       xenstored files under the /var/lib directory.
250
251
252
253       xenstored_var_log_t
254
255       - Set files with the xenstored_var_log_t type, if you want to treat the
256       data  as  xenstored  var  log  data,  usually stored under the /var/log
257       directory.
258
259
260
261       xenstored_var_run_t
262
263       - Set files with the xenstored_var_run_t type, if you want to store the
264       xenstored files under the /run or /var/run directory.
265
266
267       Paths:
268            /var/run/xenstored(/.*)?, /var/run/xenstore.pid
269
270
271       Note:  File context can be temporarily modified with the chcon command.
272       If you want to permanently change the file context you need to use  the
273       semanage fcontext command.  This will modify the SELinux labeling data‐
274       base.  You will need to use restorecon to apply the labels.
275
276

COMMANDS

278       semanage fcontext can also be used to manipulate default  file  context
279       mappings.
280
281       semanage  permissive  can  also  be used to manipulate whether or not a
282       process type is permissive.
283
284       semanage module can also be used to enable/disable/install/remove  pol‐
285       icy modules.
286
287       semanage boolean can also be used to manipulate the booleans
288
289
290       system-config-selinux is a GUI tool available to customize SELinux pol‐
291       icy settings.
