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 allow all domains to execute in fips_mode, you must turn
63 on the fips_mode boolean. Enabled by default.
64 setsebool -P fips_mode 1
66
70 SELinux defines port types to represent TCP and UDP ports.
71 You can see the types associated with a port by using the following
73 command:
74 semanage port -l
76 Policy governs the access confined processes have to these ports.
79 SELinux openvswitch policy is very flexible allowing users to setup
80 their openvswitch processes in as secure a method as possible.
81 The following port types are defined for openvswitch:
83 openvswitch_port_t
86 Default Defined Ports:
90 tcp 6634
91
93 The SELinux process type openvswitch_t can manage files labeled with
94 the following file types. The paths listed are the default paths for
95 these file types. Note the processes UID still need to have DAC per‐
96 missions.

184 SELinux requires files to have an extended attribute to define the file
185 type.
186 You can see the context of a file using the -Z option to ls
188 Policy governs the access confined processes have to these files.
190 SELinux openvswitch policy is very flexible allowing users to setup
191 their openvswitch processes in as secure a method as possible.
192 STANDARD FILE CONTEXT
194 SELinux defines the file context types for the openvswitch, if you
196 wanted to store files with these types in a diffent paths, you need to
197 execute the semanage command to specify alternate labeling and then use
198 restorecon to put the labels on disk.
199 semanage fcontext -a -t openvswitch_unit_file_t '/srv/myopen‐
201 vswitch_content(/.*)?'
202 restorecon -R -v /srv/myopenvswitch_content
203 Note: SELinux often uses regular expressions to specify labels that
205 match multiple files.
206 The following file types are defined for openvswitch:
208 openvswitch_exec_t
212 - Set files with the openvswitch_exec_t type, if you want to transition
214 an executable to the openvswitch_t domain.
215 Paths:
218 /usr/bin/ovs-vsctl, /usr/bin/ovs-appctl, /usr/sbin/ovsdb-ctl,
219 /usr/sbin/ovs-vswitchd, /usr/sbin/ovsdb-server, /usr/share/open‐
220 vswitch/scripts/ovs-ctl
221 openvswitch_log_t
224 - Set files with the openvswitch_log_t type, if you want to treat the
226 data as openvswitch log data, usually stored under the /var/log direc‐
227 tory.
228 openvswitch_rw_t
232 - Set files with the openvswitch_rw_t type, if you want to treat the
234 files as openvswitch read/write content.
235 openvswitch_tmp_t
239 - Set files with the openvswitch_tmp_t type, if you want to store open‐
241 vswitch temporary files in the /tmp directories.
242 openvswitch_unit_file_t
246 - Set files with the openvswitch_unit_file_t type, if you want to treat
248 the files as openvswitch unit content.
249 openvswitch_var_lib_t
253 - Set files with the openvswitch_var_lib_t type, if you want to store
255 the openvswitch files under the /var/lib directory.
256 openvswitch_var_run_t
260 - Set files with the openvswitch_var_run_t type, if you want to store
262 the openvswitch files under the /run or /var/run directory.
263 Note: File context can be temporarily modified with the chcon command.
267 If you want to permanently change the file context you need to use the
268 semanage fcontext command. This will modify the SELinux labeling data‐
269 base. You will need to use restorecon to apply the labels.
270
273 semanage fcontext can also be used to manipulate default file context
274 mappings.
275 semanage permissive can also be used to manipulate whether or not a
277 process type is permissive.
278 semanage module can also be used to enable/disable/install/remove pol‐
280 icy modules.
281 semanage port can also be used to manipulate the port definitions
283 semanage boolean can also be used to manipulate the booleans
285 system-config-selinux is a GUI tool available to customize SELinux pol‐
288 icy settings.
