NAME

6       cinder_backup_selinux  -  Security  Enhanced  Linux Policy for the cin‐
7       der_backup processes
8

DESCRIPTION

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

ENTRYPOINTS

24       The  cinder_backup_t  SELinux  type  can  be entered via the file_type,
25       unlabeled_t,    proc_type,    filesystem_type,    cinder_backup_exec_t,
26       mtrr_device_t, sysctl_type file types.
27
28       The  default  entrypoint  paths  for the cinder_backup_t domain are the
29       following:
30
31       all files on the system, /usr/bin/cinder-backup, /dev/cpu/mtrr
32

PROCESS TYPES

34       SELinux defines process types (domains) for each process running on the
35       system
36
37       You can see the context of a process using the -Z option to ps
38
39       Policy  governs  the  access confined processes have to files.  SELinux
40       cinder_backup policy is very flexible allowing  users  to  setup  their
41       cinder_backup processes in as secure a method as possible.
42
43       The following process types are defined for cinder_backup:
44
45       cinder_backup_t
46
47       Note:  semanage  permissive  -a cinder_backup_t can be used to make the
48       process type cinder_backup_t permissive. SELinux does not  deny  access
49       to permissive process types, but the AVC (SELinux denials) messages are
50       still generated.
51
52

BOOLEANS

54       SELinux policy is customizable based on least  access  required.   cin‐
55       der_backup  policy  is extremely flexible and has several booleans that
56       allow you to manipulate the  policy  and  run  cinder_backup  with  the
57       tightest access possible.

90       If you want to allow unconfined executables to make their  heap  memory
91       executable.   Doing  this  is  a  really bad idea. Probably indicates a
92       badly coded executable, but could indicate an attack.  This  executable
93       should  be  reported  in  bugzilla, you must turn on the allow_execheap
94       boolean. Disabled by default.

98
99
100       If you want to allow unconfined executables to map a memory  region  as
101       both  executable  and  writable,  this  is dangerous and the executable

115
116
117       If  you  want  to allow unconfined executables to make their stack exe‐
118       cutable.  This should never, ever be necessary.  Probably  indicates  a
119       badly  coded  executable, but could indicate an attack. This executable
120       should be reported in bugzilla), you must turn on  the  allow_execstack
121       boolean. Enabled by default.

MANAGED FILES

215       The SELinux process type cinder_backup_t can manage files labeled  with
216       the  following  file types.  The paths listed are the default paths for
217       these file types.  Note the processes UID still need to have  DAC  per‐
218       missions.
219
220       file_type
221
222            all files on the system
223
224

FILE CONTEXTS

226       SELinux requires files to have an extended attribute to define the file
227       type.
228
229       You can see the context of a file using the -Z option to ls
230
231       Policy governs the access  confined  processes  have  to  these  files.
232       SELinux  cinder_backup  policy is very flexible allowing users to setup
233       their cinder_backup processes in as secure a method as possible.
234
235       STANDARD FILE CONTEXT
236
237       SELinux defines the file context types for the  cinder_backup,  if  you
238       wanted  to store files with these types in a diffent paths, you need to
239       execute the semanage command to sepecify alternate  labeling  and  then
240       use restorecon to put the labels on disk.
241
242       semanage  fcontext -a -t cinder_backup_tmp_t '/srv/mycinder_backup_con‐
243       tent(/.*)?'
244       restorecon -R -v /srv/mycinder_backup_content
245
246       Note: SELinux often uses regular expressions  to  specify  labels  that
247       match multiple files.
248
249       The following file types are defined for cinder_backup:
250
251
252
253       cinder_backup_exec_t
254
255       -  Set files with the cinder_backup_exec_t type, if you want to transi‐
256       tion an executable to the cinder_backup_t domain.
257
258
259
260       cinder_backup_initrc_exec_t
261
262       - Set files with the cinder_backup_initrc_exec_t type, if you  want  to
263       transition an executable to the cinder_backup_initrc_t domain.
264
265
266
267       cinder_backup_tmp_t
268
269       -  Set  files  with  the cinder_backup_tmp_t type, if you want to store
270       cinder backup temporary files in the /tmp directories.
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.
