6 openvswitch_selinux - Security Enhanced Linux Policy for the open‐
7 vswitch processes
8
10 Security-Enhanced Linux secures the openvswitch processes via flexible
11 mandatory access control.
12 The openvswitch processes execute with the openvswitch_t SELinux type.
14 You can check if you have these processes running by executing the ps
15 command with the -Z qualifier.
16 For example:
18 ps -eZ | grep openvswitch_t
20
24 The openvswitch_t SELinux type can be entered via the open‐
25 vswitch_exec_t file type.
26 The default entrypoint paths for the openvswitch_t domain are the fol‐
28 lowing:
29 /usr/bin/ovs-vsctl, /usr/sbin/ovsdb-ctl, /usr/bin/ovs-appctl,
31 /usr/sbin/ovsdb-server, /usr/sbin/ovs-vswitchd, /usr/share/open‐
32 vswitch/scripts/ovs-ctl
33
35 SELinux defines process types (domains) for each process running on the
36 system
37 You can see the context of a process using the -Z option to ps
39 Policy governs the access confined processes have to files. SELinux
41 openvswitch policy is very flexible allowing users to setup their open‐
42 vswitch processes in as secure a method as possible.
43 The following process types are defined for openvswitch:
45 openvswitch_t
47 Note: semanage permissive -a openvswitch_t can be used to make the
49 process type openvswitch_t permissive. SELinux does not deny access to
50 permissive process types, but the AVC (SELinux denials) messages are
51 still generated.
52
55 SELinux policy is customizable based on least access required. open‐
56 vswitch policy is extremely flexible and has several booleans that
57 allow you to manipulate the policy and run openvswitch with the tight‐
58 est access possible.
59 If you want to allow users to resolve user passwd entries directly from
63 ldap rather then using a sssd server, you must turn on the authlo‐
64 gin_nsswitch_use_ldap boolean. Disabled by default.

180 SELinux defines port types to represent TCP and UDP ports.
181 You can see the types associated with a port by using the following
183 command:
184 semanage port -l
186 Policy governs the access confined processes have to these ports.
189 SELinux openvswitch policy is very flexible allowing users to setup
190 their openvswitch processes in as secure a method as possible.
191 The following port types are defined for openvswitch:
193 openvswitch_port_t
196 Default Defined Ports:
200 tcp 6634
201
203 The SELinux process type openvswitch_t can manage files labeled with
204 the following file types. The paths listed are the default paths for
205 these file types. Note the processes UID still need to have DAC per‐
206 missions.

279 SELinux requires files to have an extended attribute to define the file
280 type.
281 You can see the context of a file using the -Z option to ls
283 Policy governs the access confined processes have to these files.
285 SELinux openvswitch policy is very flexible allowing users to setup
286 their openvswitch processes in as secure a method as possible.
287 STANDARD FILE CONTEXT
289 SELinux defines the file context types for the openvswitch, if you
291 wanted to store files with these types in a diffent paths, you need to
292 execute the semanage command to sepecify alternate labeling and then
293 use restorecon to put the labels on disk.
294 semanage fcontext -a -t openvswitch_var_run_t '/srv/myopenvswitch_con‐
296 tent(/.*)?'
297 restorecon -R -v /srv/myopenvswitch_content
298 Note: SELinux often uses regular expressions to specify labels that
300 match multiple files.
301 The following file types are defined for openvswitch:
303 openvswitch_exec_t
307 - Set files with the openvswitch_exec_t type, if you want to transition
309 an executable to the openvswitch_t domain.
310 Paths:
313 /usr/bin/ovs-vsctl, /usr/sbin/ovsdb-ctl, /usr/bin/ovs-appctl,
314 /usr/sbin/ovsdb-server, /usr/sbin/ovs-vswitchd, /usr/share/open‐
315 vswitch/scripts/ovs-ctl
316 openvswitch_log_t
319 - Set files with the openvswitch_log_t type, if you want to treat the
321 data as openvswitch log data, usually stored under the /var/log direc‐
322 tory.
323 openvswitch_rw_t
327 - Set files with the openvswitch_rw_t type, if you want to treat the
329 files as openvswitch read/write content.
330 openvswitch_tmp_t
334 - Set files with the openvswitch_tmp_t type, if you want to store open‐
336 vswitch temporary files in the /tmp directories.
337 openvswitch_unit_file_t
341 - Set files with the openvswitch_unit_file_t type, if you want to treat
343 the files as openvswitch unit content.
344 openvswitch_var_lib_t
348 - Set files with the openvswitch_var_lib_t type, if you want to store
350 the openvswitch files under the /var/lib directory.
351 openvswitch_var_run_t
355 - Set files with the openvswitch_var_run_t type, if you want to store
357 the openvswitch files under the /run or /var/run directory.
358 Note: File context can be temporarily modified with the chcon command.
362 If you want to permanently change the file context you need to use the
363 semanage fcontext command. This will modify the SELinux labeling data‐
364 base. You will need to use restorecon to apply the labels.
365
368 semanage fcontext can also be used to manipulate default file context
369 mappings.
370 semanage permissive can also be used to manipulate whether or not a
372 process type is permissive.
373 semanage module can also be used to enable/disable/install/remove pol‐
375 icy modules.
376 semanage port can also be used to manipulate the port definitions
378 semanage boolean can also be used to manipulate the booleans
380 system-config-selinux is a GUI tool available to customize SELinux pol‐
383 icy settings.
