NAME

6       cinder_api_selinux  - Security Enhanced Linux Policy for the cinder_api
7       processes
8

DESCRIPTION

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

ENTRYPOINTS

24       The  cinder_api_t SELinux type can be entered via the cinder_api_exec_t
25       file type.
26
27       The default entrypoint paths for the cinder_api_t domain are  the  fol‐
28       lowing:
29
30       /usr/bin/cinder-api
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_api  policy  is very flexible allowing users to setup their cin‐
40       der_api processes in as secure a method as possible.
41
42       The following process types are defined for cinder_api:
43
44       cinder_api_t
45
46       Note: semanage permissive -a cinder_api_t  can  be  used  to  make  the
47       process  type  cinder_api_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.  cin‐
54       der_api policy is extremely flexible  and  has  several  booleans  that
55       allow you to manipulate the policy and run cinder_api with the tightest
56       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

145
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.
153
154       setsebool -P mmap_low_allowed 1
155

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

MANAGED FILES

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

FILE CONTEXTS

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

COMMANDS

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