NAME

6       neutron_selinux  -  Security Enhanced Linux Policy for the neutron pro‐
7       cesses
8

DESCRIPTION

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

ENTRYPOINTS

24       The  neutron_t  SELinux  type  can  be entered via the file_type, unla‐
25       beled_t, proc_type, filesystem_type, mtrr_device_t,  sysctl_type,  neu‐
26       tron_exec_t file types.
27
28       The  default  entrypoint paths for the neutron_t domain are the follow‐
29       ing:
30
31       all  files  on  the  system,  /dev/cpu/mtrr,   /usr/bin/neutron-server,
32       /usr/bin/quantum-server,  /usr/bin/neutron-l3-agent,  /usr/bin/neutron-
33       rootwrap,     /usr/bin/quantum-l3-agent,     /usr/bin/quantum-rootwrap,
34       /usr/bin/neutron-ryu-agent,  /usr/bin/quantum-ryu-agent,  /usr/bin/neu‐
35       tron-dhcp-agent,  /usr/bin/quantum-dhcp-agent,  /usr/bin/neutron-lbaas-
36       agent,    /usr/bin/neutron-ovs-cleanup,   /usr/bin/quantum-lbaas-agent,
37       /usr/bin/quantum-ovs-cleanup,       /usr/bin/neutron-openvswitch-agent,
38       /usr/bin/neutron-linuxbridge-agent, /usr/bin/quantum-openvswitch-agent,
39       /usr/bin/quantum-linuxbridge-agent

PROCESS TYPES

42       SELinux defines process types (domains) for each process running on the
43       system
44
45       You can see the context of a process using the -Z option to ps
46
47       Policy  governs  the  access confined processes have to files.  SELinux
48       neutron policy is very flexible allowing users to setup  their  neutron
49       processes in as secure a method as possible.
50
51       The following process types are defined for neutron:
52
53       neutron_t
54
55       Note:  semanage permissive -a neutron_t can be used to make the process
56       type neutron_t permissive. SELinux does not deny access  to  permissive
57       process  types, but the AVC (SELinux denials) messages are still gener‐
58       ated.
59
60

BOOLEANS

62       SELinux policy is customizable based on least access required.  neutron
63       policy is extremely flexible and has several booleans that allow you to
64       manipulate the policy and run neutron with the tightest  access  possi‐
65       ble.

125       If  you  want  to allow unconfined executables to make their stack exe‐
126       cutable.  This should never, ever be necessary.  Probably  indicates  a
127       badly  coded  executable, but could indicate an attack. This executable
128       should be reported in bugzilla), you must turn on  the  allow_execstack

161
162
163       If  you  want to allow all domains to have the kernel load modules, you
164       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by

221

PORT TYPES

223       SELinux defines port types to represent TCP and UDP ports.
224
225       You can see the types associated with a port  by  using  the  following
226       command:
227
228       semanage port -l
229
230
231       Policy  governs  the  access  confined  processes  have to these ports.
232       SELinux neutron policy is very flexible allowing users to  setup  their
233       neutron processes in as secure a method as possible.
234
235       The following port types are defined for neutron:
236
237
238       neutron_port_t
239
240
241
242       Default Defined Ports:
243                 tcp 9696
244

MANAGED FILES

246       The  SELinux  process  type neutron_t can manage files labeled with the
247       following file types.  The paths listed are the default paths for these
248       file types.  Note the processes UID still need to have DAC permissions.
249
250       file_type
251
252            all files on the system
253
254

FILE CONTEXTS

256       SELinux requires files to have an extended attribute to define the file
257       type.
258
259       You can see the context of a file using the -Z option to ls
260
261       Policy governs the access  confined  processes  have  to  these  files.
262       SELinux  neutron  policy is very flexible allowing users to setup their
263       neutron processes in as secure a method as possible.
264
265       STANDARD FILE CONTEXT
266
267       SELinux defines the file context types for the neutron, if  you  wanted
268       to store files with these types in a diffent paths, you need to execute
269       the semanage command  to  sepecify  alternate  labeling  and  then  use
270       restorecon to put the labels on disk.
271
272       semanage   fcontext   -a   -t   neutron_var_run_t  '/srv/myneutron_con‐
273       tent(/.*)?'
274       restorecon -R -v /srv/myneutron_content
275
276       Note: SELinux often uses regular expressions  to  specify  labels  that
277       match multiple files.
278
279       The following file types are defined for neutron:
280
281
282
283       neutron_exec_t
284
285       -  Set files with the neutron_exec_t type, if you want to transition an
286       executable to the neutron_t domain.
287
288
289       Paths:
290            /usr/bin/neutron-server,  /usr/bin/quantum-server,   /usr/bin/neu‐
291            tron-l3-agent,     /usr/bin/neutron-rootwrap,    /usr/bin/quantum-
292            l3-agent,  /usr/bin/quantum-rootwrap,  /usr/bin/neutron-ryu-agent,
293            /usr/bin/quantum-ryu-agent,           /usr/bin/neutron-dhcp-agent,
294            /usr/bin/quantum-dhcp-agent,         /usr/bin/neutron-lbaas-agent,
295            /usr/bin/neutron-ovs-cleanup,        /usr/bin/quantum-lbaas-agent,
296            /usr/bin/quantum-ovs-cleanup,  /usr/bin/neutron-openvswitch-agent,
297            /usr/bin/neutron-linuxbridge-agent,  /usr/bin/quantum-openvswitch-
298            agent, /usr/bin/quantum-linuxbridge-agent
299
300
301       neutron_initrc_exec_t
302
303       - Set files with the neutron_initrc_exec_t type, if you want to transi‐
304       tion an executable to the neutron_initrc_t domain.
305
306
307       Paths:
308            /etc/rc.d/init.d/quantum.*, /etc/rc.d/init.d/neutron.*
309
310
311       neutron_log_t
312
313       -  Set files with the neutron_log_t type, if you want to treat the data
314       as neutron log data, usually stored under the /var/log directory.
315
316
317       Paths:
318            /var/log/quantum(/.*)?, /var/log/neutron(/.*)?
319
320
321       neutron_tmp_t
322
323       - Set files with the neutron_tmp_t type, if you want to  store  neutron
324       temporary files in the /tmp directories.
325
326
327
328       neutron_var_lib_t
329
330       -  Set  files with the neutron_var_lib_t type, if you want to store the
331       neutron files under the /var/lib directory.
332
333
334       Paths:
335            /var/lib/quantum(/.*)?, /var/lib/neutron(/.*)?
336
337
338       neutron_var_run_t
339
340       - Set files with the neutron_var_run_t type, if you want to  store  the
341       neutron files under the /run or /var/run directory.
342
343
344       Paths:
345            /var/run/quantum(/.*)?, /var/run/neutron(/.*)?
346
347
348       Note:  File context can be temporarily modified with the chcon command.
349       If you want to permanently change the file context you need to use  the
350       semanage fcontext command.  This will modify the SELinux labeling data‐
351       base.  You will need to use restorecon to apply the labels.
352
353

COMMANDS

355       semanage fcontext can also be used to manipulate default  file  context
356       mappings.
357
358       semanage  permissive  can  also  be used to manipulate whether or not a
359       process type is permissive.
360
361       semanage module can also be used to enable/disable/install/remove  pol‐
362       icy modules.
363
364       semanage port can also be used to manipulate the port definitions
365
366       semanage boolean can also be used to manipulate the booleans
367
368
369       system-config-selinux is a GUI tool available to customize SELinux pol‐
370       icy settings.
