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/bin/ovs-appctl, /usr/sbin/ovsdb-ctl,
31 /usr/sbin/ovs-vswitchd, /usr/sbin/ovsdb-server, /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 al‐
57 low you to manipulate the policy and run openvswitch with the tightest
58 access possible.
59 If you want to dontaudit all daemons scheduling requests (setsched,
63 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
64 Enabled by default.
65 setsebool -P daemons_dontaudit_scheduling 1
67 If you want to allow all domains to execute in fips_mode, you must turn
71 on the fips_mode boolean. Enabled by default.
72 setsebool -P fips_mode 1
74 If you want to allow system to run with NIS, you must turn on the
78 nis_enabled boolean. Disabled by default.
79 setsebool -P nis_enabled 1
81
85 SELinux defines port types to represent TCP and UDP ports.
86 You can see the types associated with a port by using the following
88 command:
89 semanage port -l
91 Policy governs the access confined processes have to these ports.
94 SELinux openvswitch policy is very flexible allowing users to setup
95 their openvswitch processes in as secure a method as possible.
96 The following port types are defined for openvswitch:
98 openvswitch_port_t
101 Default Defined Ports:
105 tcp 6634
106
108 The SELinux process type openvswitch_t can manage files labeled with
109 the following file types. The paths listed are the default paths for
110 these file types. Note the processes UID still need to have DAC per‐
111 missions.

199 SELinux requires files to have an extended attribute to define the file
200 type.
201 You can see the context of a file using the -Z option to ls
203 Policy governs the access confined processes have to these files.
205 SELinux openvswitch policy is very flexible allowing users to setup
206 their openvswitch processes in as secure a method as possible.
207 STANDARD FILE CONTEXT
209 SELinux defines the file context types for the openvswitch, if you
211 wanted to store files with these types in a different paths, you need
212 to execute the semanage command to specify alternate labeling and then
213 use restorecon to put the labels on disk.
214 semanage fcontext -a -t openvswitch_exec_t '/srv/openvswitch/con‐
216 tent(/.*)?'
217 restorecon -R -v /srv/myopenvswitch_content
218 Note: SELinux often uses regular expressions to specify labels that
220 match multiple files.
221 The following file types are defined for openvswitch:
223 openvswitch_exec_t
227 - Set files with the openvswitch_exec_t type, if you want to transition
229 an executable to the openvswitch_t domain.
230 Paths:
233 /usr/bin/ovs-vsctl, /usr/bin/ovs-appctl, /usr/sbin/ovsdb-ctl,
234 /usr/sbin/ovs-vswitchd, /usr/sbin/ovsdb-server, /usr/share/open‐
235 vswitch/scripts/ovs-ctl
236 openvswitch_log_t
239 - Set files with the openvswitch_log_t type, if you want to treat the
241 data as openvswitch log data, usually stored under the /var/log direc‐
242 tory.
243 openvswitch_rw_t
247 - Set files with the openvswitch_rw_t type, if you want to treat the
249 files as openvswitch read/write content.
250 openvswitch_tmp_t
254 - Set files with the openvswitch_tmp_t type, if you want to store open‐
256 vswitch temporary files in the /tmp directories.
257 openvswitch_tmpfs_t
261 - Set files with the openvswitch_tmpfs_t type, if you want to store
263 openvswitch files on a tmpfs file system.
264 openvswitch_unit_file_t
268 - Set files with the openvswitch_unit_file_t type, if you want to treat
270 the files as openvswitch unit content.
271 openvswitch_var_lib_t
275 - Set files with the openvswitch_var_lib_t type, if you want to store
277 the openvswitch files under the /var/lib directory.
278 openvswitch_var_run_t
282 - Set files with the openvswitch_var_run_t type, if you want to store
284 the openvswitch files under the /run or /var/run directory.
285 Note: File context can be temporarily modified with the chcon command.
289 If you want to permanently change the file context you need to use the
290 semanage fcontext command. This will modify the SELinux labeling data‐
291 base. You will need to use restorecon to apply the labels.
292
295 semanage fcontext can also be used to manipulate default file context
296 mappings.
297 semanage permissive can also be used to manipulate whether or not a
299 process type is permissive.
300 semanage module can also be used to enable/disable/install/remove pol‐
302 icy modules.
303 semanage port can also be used to manipulate the port definitions
305 semanage boolean can also be used to manipulate the booleans
307 system-config-selinux is a GUI tool available to customize SELinux pol‐
310 icy settings.
