6 neutron_selinux - Security Enhanced Linux Policy for the neutron pro‐
7 cesses
8
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
24 The neutron_t SELinux type can be entered via the neutron_exec_t file
25 type.
26
27 The default entrypoint paths for the neutron_t domain are the follow‐
28 ing:
29
30 /usr/bin/neutron-server, /usr/bin/quantum-server, /usr/bin/neutron-
31 l3-agent, /usr/bin/neutron-rootwrap, /usr/bin/quantum-l3-agent,
32 /usr/bin/neutron-ryu-agent, /usr/bin/quantum-ryu-agent, /usr/bin/neu‐
33 tron-dhcp-agent, /usr/bin/quantum-dhcp-agent, /usr/bin/neutron-lbaas-
34 agent, /usr/bin/neutron-ovs-cleanup, /usr/bin/quantum-ovs-cleanup,
35 /usr/bin/neutron-netns-cleanup, /usr/bin/neutron-metadata-agent,
36 /usr/bin/neutron-linuxbridge-agent, /usr/bin/neutron-ns-metadata-proxy,
37 /usr/bin/neutron-openvswitch-agent, /usr/bin/quantum-linuxbridge-agent,
38 /usr/bin/quantum-openvswitch-agent

41 SELinux defines process types (domains) for each process running on the
42 system
43
44 You can see the context of a process using the -Z option to ps
45
46 Policy governs the access confined processes have to files. SELinux
47 neutron policy is very flexible allowing users to setup their neutron
48 processes in as secure a method as possible.
49
50 The following process types are defined for neutron:
51
52 neutron_t
53
54 Note: semanage permissive -a neutron_t can be used to make the process
55 type neutron_t permissive. SELinux does not deny access to permissive
56 process types, but the AVC (SELinux denials) messages are still gener‐
57 ated.
58
59
61 SELinux policy is customizable based on least access required. neutron
62 policy is extremely flexible and has several booleans that allow you to
63 manipulate the policy and run neutron with the tightest access possi‐
64 ble.
65
66
67
68 If you want to determine whether neutron can connect to all TCP ports,
69 you must turn on the neutron_can_network boolean. Disabled by default.
70
71 setsebool -P neutron_can_network 1
72
73
74
75 If you want to allow users to resolve user passwd entries directly from
76 ldap rather then using a sssd server, you must turn on the authlo‐
77 gin_nsswitch_use_ldap boolean. Disabled by default.
78
79 setsebool -P authlogin_nsswitch_use_ldap 1
80
81
82
83 If you want to allow all domains to execute in fips_mode, you must turn
84 on the fips_mode boolean. Enabled by default.
85
86 setsebool -P fips_mode 1
87
88
89
90 If you want to allow confined applications to run with kerberos, you
91 must turn on the kerberos_enabled boolean. Disabled by default.
92
93 setsebool -P kerberos_enabled 1
94
95
96
97 If you want to allow system to run with NIS, you must turn on the
98 nis_enabled boolean. Disabled by default.
99
100 setsebool -P nis_enabled 1
101
102
103
104 If you want to allow confined applications to use nscd shared memory,
105 you must turn on the nscd_use_shm boolean. Disabled by default.
106
107 setsebool -P nscd_use_shm 1
108
109
110
112 SELinux defines port types to represent TCP and UDP ports.
113
114 You can see the types associated with a port by using the following
115 command:
116
117 semanage port -l
118
119
120 Policy governs the access confined processes have to these ports.
121 SELinux neutron policy is very flexible allowing users to setup their
122 neutron processes in as secure a method as possible.
123
124 The following port types are defined for neutron:
125
126
127 neutron_port_t
128
129
130
131 Default Defined Ports:
132 tcp 8775,9696,9697
133
135 The SELinux process type neutron_t can manage files labeled with the
136 following file types. The paths listed are the default paths for these
137 file types. Note the processes UID still need to have DAC permissions.

235 SELinux requires files to have an extended attribute to define the file
236 type.
237
238 You can see the context of a file using the -Z option to ls
239
240 Policy governs the access confined processes have to these files.
241 SELinux neutron policy is very flexible allowing users to setup their
242 neutron processes in as secure a method as possible.
243
244 STANDARD FILE CONTEXT
245
246 SELinux defines the file context types for the neutron, if you wanted
247 to store files with these types in a diffent paths, you need to execute
248 the semanage command to sepecify alternate labeling and then use
249 restorecon to put the labels on disk.
250
251 semanage fcontext -a -t neutron_unit_file_t '/srv/myneutron_con‐
252 tent(/.*)?'
253 restorecon -R -v /srv/myneutron_content
254
255 Note: SELinux often uses regular expressions to specify labels that
256 match multiple files.
257
258 The following file types are defined for neutron:
259
260
261
262 neutron_exec_t
263
264 - Set files with the neutron_exec_t type, if you want to transition an
265 executable to the neutron_t domain.
266
267
268 Paths:
269 /usr/bin/neutron-server, /usr/bin/quantum-server, /usr/bin/neu‐
270 tron-l3-agent, /usr/bin/neutron-rootwrap, /usr/bin/quantum-
271 l3-agent, /usr/bin/neutron-ryu-agent, /usr/bin/quantum-ryu-agent,
272 /usr/bin/neutron-dhcp-agent, /usr/bin/quantum-dhcp-agent,
273 /usr/bin/neutron-lbaas-agent, /usr/bin/neutron-ovs-cleanup,
274 /usr/bin/quantum-ovs-cleanup, /usr/bin/neutron-netns-cleanup,
275 /usr/bin/neutron-metadata-agent, /usr/bin/neutron-linuxbridge-
276 agent, /usr/bin/neutron-ns-metadata-proxy, /usr/bin/neutron-open‐
277 vswitch-agent, /usr/bin/quantum-linuxbridge-agent, /usr/bin/quan‐
278 tum-openvswitch-agent
279
280
281 neutron_initrc_exec_t
282
283 - Set files with the neutron_initrc_exec_t type, if you want to transi‐
284 tion an executable to the neutron_initrc_t domain.
285
286
287 Paths:
288 /etc/rc.d/init.d/neutron.*, /etc/rc.d/init.d/quantum.*
289
290
291 neutron_log_t
292
293 - Set files with the neutron_log_t type, if you want to treat the data
294 as neutron log data, usually stored under the /var/log directory.
295
296
297 Paths:
298 /var/log/neutron(/.*)?, /var/log/quantum(/.*)?
299
300
301 neutron_tmp_t
302
303 - Set files with the neutron_tmp_t type, if you want to store neutron
304 temporary files in the /tmp directories.
305
306
307
308 neutron_unit_file_t
309
310 - Set files with the neutron_unit_file_t type, if you want to treat the
311 files as neutron unit content.
312
313
314 Paths:
315 /usr/lib/systemd/system/neutron.*, /usr/lib/systemd/system/quan‐
316 tum.*
317
318
319 neutron_var_lib_t
320
321 - Set files with the neutron_var_lib_t type, if you want to store the
322 neutron files under the /var/lib directory.
323
324
325 Paths:
326 /var/lib/neutron(/.*)?, /var/lib/quantum(/.*)?
327
328
329 neutron_var_run_t
330
331 - Set files with the neutron_var_run_t type, if you want to store the
332 neutron files under the /run or /var/run directory.
333
334
335 Paths:
336 /var/run/neutron(/.*)?, /var/run/quantum(/.*)?
337
338
339 Note: File context can be temporarily modified with the chcon command.
340 If you want to permanently change the file context you need to use the
341 semanage fcontext command. This will modify the SELinux labeling data‐
342 base. You will need to use restorecon to apply the labels.
343
344
346 semanage fcontext can also be used to manipulate default file context
347 mappings.
348
349 semanage permissive can also be used to manipulate whether or not a
350 process type is permissive.
351
352 semanage module can also be used to enable/disable/install/remove pol‐
353 icy modules.
354
355 semanage port can also be used to manipulate the port definitions
356
357 semanage boolean can also be used to manipulate the booleans
358
359
360 system-config-selinux is a GUI tool available to customize SELinux pol‐
361 icy settings.
