NAME

6       cinder_scheduler_selinux  - Security Enhanced Linux Policy for the cin‐
7       der_scheduler processes
8

DESCRIPTION

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

ENTRYPOINTS

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

BOOLEANS

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

85
86
87
88       If you want to deny user domains applications to map a memory region as
89       both  executable  and  writable,  this  is dangerous and the executable
90       should be reported in bugzilla, you must turn on the deny_execmem bool‐
91       ean. Enabled by default.
92
93       setsebool -P deny_execmem 1

114       executed with systemd.log_target=kmsg parameter, you must turn  on  the
115       domain_can_write_kmsg boolean. Disabled by default.
116
117       setsebool -P domain_can_write_kmsg 1
118
119
120
121       If you want to allow all domains to use other domains file descriptors,
122       you must turn on the domain_fd_use boolean. Enabled by default.
123
124       setsebool -P domain_fd_use 1
125
126
127
128       If you want to allow all domains to have the kernel load  modules,  you
129       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by

146       setsebool -P global_ssp 1
147
148
149
150       If you want to control the ability to mmap a low area  of  the  address
151       space,  as  configured  by /proc/sys/vm/mmap_min_addr, you must turn on
152       the mmap_low_allowed boolean. Disabled by default.

163
164
165       If  you want to boolean to determine whether the system permits loading
166       policy, setting enforcing mode, and changing boolean values.  Set  this
167       to  true  and  you  have to reboot to set it back, you must turn on the
168       secure_mode_policyload boolean. Enabled by default.
169
170       setsebool -P secure_mode_policyload 1
171
172
173
174       If you want to allow unconfined executables to make their  heap  memory
175       executable.   Doing  this  is  a  really bad idea. Probably indicates a
176       badly coded executable, but could indicate an attack.  This  executable
177       should   be   reported  in  bugzilla,  you  must  turn  on  the  selin‐
178       uxuser_execheap boolean. Disabled by default.
179
180       setsebool -P selinuxuser_execheap 1
181
182
183
184       If you want to  allow  all  unconfined  executables  to  use  libraries
185       requiring  text  relocation  that  are not labeled textrel_shlib_t, you
186       must turn on the selinuxuser_execmod boolean. Enabled by default.
187
188       setsebool -P selinuxuser_execmod 1
189
190
191
192       If you want to allow unconfined executables to make  their  stack  exe‐
193       cutable.   This  should  never, ever be necessary. Probably indicates a
194       badly coded executable, but could indicate an attack.  This  executable
195       should  be reported in bugzilla, you must turn on the selinuxuser_exec‐
196       stack boolean. Enabled by default.
197
198       setsebool -P selinuxuser_execstack 1
199
200
201
202       If you want to support X userspace object manager, you must turn on the
203       xserver_object_manager boolean. Enabled by default.
204
205       setsebool -P xserver_object_manager 1
206

MANAGED FILES

210       The  SELinux  process  type cinder_scheduler_t can manage files labeled
211       with the following file types.  The paths listed are the default  paths
212       for  these  file  types.  Note the processes UID still need to have DAC
213       permissions.
214
215       file_type
216
217            all files on the system
218
219

FILE CONTEXTS

221       SELinux requires files to have an extended attribute to define the file
222       type.
223
224       You can see the context of a file using the -Z option to ls
225
226       Policy  governs  the  access  confined  processes  have to these files.
227       SELinux cinder_scheduler policy is very flexible allowing users to set‐
228       up their cinder_scheduler processes in as secure a method as possible.
229
230       STANDARD FILE CONTEXT
231
232       SELinux defines the file context types for the cinder_scheduler, if you
233       wanted to store files with these types in a diffent paths, you need  to
234       execute  the  semanage  command to sepecify alternate labeling and then
235       use restorecon to put the labels on disk.
236
237       semanage  fcontext  -a  -t  cinder_scheduler_unit_file_t   '/srv/mycin‐
238       der_scheduler_content(/.*)?'
239       restorecon -R -v /srv/mycinder_scheduler_content
240
241       Note:  SELinux  often  uses  regular expressions to specify labels that
242       match multiple files.
243
244       The following file types are defined for cinder_scheduler:
245
246
247
248       cinder_scheduler_exec_t
249
250       - Set files with the cinder_scheduler_exec_t type, if you want to tran‐
251       sition an executable to the cinder_scheduler_t domain.
252
253
254
255       cinder_scheduler_tmp_t
256
257       -  Set files with the cinder_scheduler_tmp_t type, if you want to store
258       cinder scheduler temporary files in the /tmp directories.
259
260
261
262       cinder_scheduler_unit_file_t
263
264       - Set files with the cinder_scheduler_unit_file_t type, if you want  to
265       treat the files as cinder scheduler unit content.
266
267
268
269       Note:  File context can be temporarily modified with the chcon command.
270       If you want to permanently change the file context you need to use  the
271       semanage fcontext command.  This will modify the SELinux labeling data‐
272       base.  You will need to use restorecon to apply the labels.
273
274

COMMANDS

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