NAME

       openvswitch_selinux - Security Enhanced Linux Policy for the openvswitch processes

DESCRIPTION

       Security-Enhanced Linux secures the openvswitch processes via flexible mandatory access control.

       The  openvswitch  processes execute with the openvswitch_t SELinux type. You can check if you have these processes running by executing the
       ps command with the -Z qualifier.

       For example:

       ps -eZ | grep openvswitch_t

ENTRYPOINTS

       The openvswitch_t SELinux type can be entered via the openvswitch_exec_t file type.

       The default entrypoint paths for the openvswitch_t domain are the following:

       /usr/bin/ovs-vsctl,   /usr/sbin/ovsdb-ctl,   /usr/bin/ovs-appctl,    /usr/sbin/ovsdb-server,    /usr/sbin/ovs-vswitchd,	  /usr/share/open-
       vswitch/scripts/ovs-ctl

PROCESS TYPES

       SELinux defines process types (domains) for each process running on the system

       You can see the context of a process using the -Z option to ps

       Policy  governs	the  access  confined  processes have to files.  SELinux openvswitch policy is very flexible allowing users to setup their
       openvswitch processes in as secure a method as possible.

       The following process types are defined for openvswitch:

       openvswitch_t

       Note: semanage permissive -a openvswitch_t can be used to make the process type openvswitch_t permissive. SELinux does not deny	access	to
       permissive process types, but the AVC (SELinux denials) messages are still generated.

BOOLEANS

       SELinux	policy	is  customizable  based  on least access required.  openvswitch policy is extremely flexible and has several booleans that
       allow you to manipulate the policy and run openvswitch with the tightest access possible.

       If you want to allow all daemons to write corefiles to /, you must turn on the daemons_dump_core boolean. Disabled by default.

       setsebool -P daemons_dump_core 1

       If you want to enable cluster mode for daemons, you must turn on the daemons_enable_cluster_mode boolean. Enabled by default.

       setsebool -P daemons_enable_cluster_mode 1

       If you want to allow all daemons to use tcp wrappers, you must turn on the daemons_use_tcp_wrapper boolean. Disabled by default.

       setsebool -P daemons_use_tcp_wrapper 1

       If you want to allow all daemons the ability to read/write terminals, you must turn on the daemons_use_tty boolean. Disabled by default.

       setsebool -P daemons_use_tty 1

       If you want to deny any process from ptracing or debugging any other processes, you must  turn  on  the	deny_ptrace  boolean.  Enabled	by
       default.

       setsebool -P deny_ptrace 1

       If you want to allow all domains to use other domains file descriptors, you must turn on the domain_fd_use boolean. Enabled by default.

       setsebool -P domain_fd_use 1

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

       setsebool -P domain_kernel_load_modules 1

       If you want to allow all domains to execute in fips_mode, you must turn on the fips_mode boolean. Enabled by default.

       setsebool -P fips_mode 1

       If you want to enable reading of urandom for all domains, you must turn on the global_ssp boolean. Disabled by default.

       setsebool -P global_ssp 1

       If you want to allow confined applications to use nscd shared memory, you must turn on the nscd_use_shm boolean. Enabled by default.

       setsebool -P nscd_use_shm 1

PORT TYPES

       SELinux defines port types to represent TCP and UDP ports.

       You can see the types associated with a port by using the following command:

       semanage port -l

       Policy governs the access confined processes have to these ports.  SELinux openvswitch policy is very  flexible	allowing  users  to  setup
       their openvswitch processes in as secure a method as possible.

       The following port types are defined for openvswitch:

       openvswitch_port_t

       Default Defined Ports:
		 tcp 6634

MANAGED FILES

       The  SELinux process type openvswitch_t can manage files labeled with the following file types.	The paths listed are the default paths for
       these file types.  Note the processes UID still need to have DAC permissions.

       cluster_conf_t

	    /etc/cluster(/.*)?

       cluster_var_lib_t

	    /var/lib/pcsd(/.*)?
	    /var/lib/cluster(/.*)?
	    /var/lib/openais(/.*)?
	    /var/lib/pengine(/.*)?
	    /var/lib/corosync(/.*)?
	    /usr/lib/heartbeat(/.*)?
	    /var/lib/heartbeat(/.*)?
	    /var/lib/pacemaker(/.*)?

       cluster_var_run_t

	    /var/run/crm(/.*)?

       openvswitch_var_lib_t

	    /var/lib/openvswitch(/.*)?

       openvswitch_var_run_t

	    /var/run/openvswitch(/.*)?

       root_t

	    /
	    /initrd

FILE CONTEXTS

       SELinux requires files to have an extended attribute to define the file type.

       You can see the context of a file using the -Z option to ls

       Policy governs the access confined processes have to these files.  SELinux openvswitch policy is very  flexible	allowing  users  to  setup
       their openvswitch processes in as secure a method as possible.

       STANDARD FILE CONTEXT

       SELinux	defines  the file context types for the openvswitch, if you wanted to store files with these types in a diffent paths, you need to
       execute the semanage command to sepecify alternate labeling and then use restorecon to put the labels on disk.

       semanage fcontext -a -t openvswitch_exec_t '/srv/openvswitch/content(/.*)?'
       restorecon -R -v /srv/myopenvswitch_content

       Note: SELinux often uses regular expressions to specify labels that match multiple files.

       The following file types are defined for openvswitch:

       openvswitch_exec_t

       - Set files with the openvswitch_exec_t type, if you want to transition an executable to the openvswitch_t domain.

       Paths:
	    /usr/bin/ovs-vsctl,  /usr/sbin/ovsdb-ctl,  /usr/bin/ovs-appctl,   /usr/sbin/ovsdb-server,	/usr/sbin/ovs-vswitchd,   /usr/share/open-
	    vswitch/scripts/ovs-ctl

       openvswitch_log_t

       -  Set  files  with  the  openvswitch_log_t  type, if you want to treat the data as openvswitch log data, usually stored under the /var/log
       directory.

       openvswitch_rw_t

       - Set files with the openvswitch_rw_t type, if you want to treat the files as openvswitch read/write content.

       openvswitch_tmp_t

       - Set files with the openvswitch_tmp_t type, if you want to store openvswitch temporary files in the /tmp directories.

       openvswitch_unit_file_t

       - Set files with the openvswitch_unit_file_t type, if you want to treat the files as openvswitch unit content.

       openvswitch_var_lib_t

       - Set files with the openvswitch_var_lib_t type, if you want to store the openvswitch files under the /var/lib directory.

       openvswitch_var_run_t

       - Set files with the openvswitch_var_run_t type, if you want to store the openvswitch files under the /run or /var/run directory.

       Note: File context can be temporarily modified with the chcon command.  If you want to permanently change the file context you need to  use
       the semanage fcontext command.  This will modify the SELinux labeling database.	You will need to use restorecon to apply the labels.

COMMANDS

       semanage fcontext can also be used to manipulate default file context mappings.

       semanage permissive can also be used to manipulate whether or not a process type is permissive.

       semanage module can also be used to enable/disable/install/remove policy modules.

       semanage port can also be used to manipulate the port definitions

       semanage boolean can also be used to manipulate the booleans

       system-config-selinux is a GUI tool available to customize SELinux policy settings.
