NAMEopenvpn_selinux − Security Enhanced Linux Policy for the openvpn processes
DESCRIPTIONSecurity-Enhanced Linux secures the openvpn processes via flexible mandatory access control. The openvpn processes execute with the openvpn_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 openvpn_t
ENTRYPOINTSThe openvpn_t SELinux type can be entered via the openvpn_exec_t file type. The default entrypoint paths for the openvpn_t domain are the following: /usr/sbin/openvpn
PROCESS TYPESSELinux 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 openvpn policy is very flexible allowing users to setup their openvpn processes in as secure a method as possible. The following process types are defined for openvpn: openvpn_t, openvpn_unconfined_script_tNote: semanage permissive -a openvpn_t can be used to make the process type openvpn_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.
BOOLEANSSELinux policy is customizable based on least access required. openvpn policy is extremely flexible and has several booleans that allow you to manipulate the policy and run openvpn with the tightest access possible. If you want to determine whether openvpn can connect to the TCP network, you must turn on the openvpn_can_network_connect boolean. Enabled by default. setsebool -P openvpn_can_network_connect 1
If you want to allow openvpn to run unconfined scripts, you must turn on the openvpn_run_unconfined boolean. Disabled by default. setsebool -P openvpn_run_unconfined 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 allow confined applications to run with kerberos, you must turn on the kerberos_enabled boolean. Enabled by default. setsebool -P kerberos_enabled 1
If you want to allow system to run with NIS, you must turn on the nis_enabled boolean. Disabled by default. setsebool -P nis_enabled 1
If you want to support ecryptfs home directories, you must turn on the use_ecryptfs_home_dirs boolean. Disabled by default. setsebool -P use_ecryptfs_home_dirs 1
PORT TYPESSELinux 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 openvpn policy is very flexible allowing users to setup their openvpn processes in as secure a method as possible. The following port types are defined for openvpn: openvpn_port_t
Default Defined Ports: tcp 1194 udp 1194
MANAGED FILESThe SELinux process type openvpn_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.

FILE CONTEXTSSELinux 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 openvpn policy is very flexible allowing users to setup their openvpn processes in as secure a method as possible. EQUIVALENCE DIRECTORIES openvpn policy stores data with multiple different file context types under the /var/run/openvpn directory. If you would like to store the data in a different directory you can use the semanage command to create an equivalence mapping. If you wanted to store this data under the /srv directory you would execute the following command: semanage fcontext -a -e /var/run/openvpn /srv/openvpn
restorecon -R -v /srv/openvpn STANDARD FILE CONTEXT SELinux defines the file context types for the openvpn, 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 openvpn_var_run_t '/srv/myopenvpn_content(/.*)?'
restorecon -R -v /srv/myopenvpn_content Note: SELinux often uses regular expressions to specify labels that match multiple files. The following file types are defined for openvpn: openvpn_etc_rw_t- Set files with the openvpn_etc_rw_t type, if you want to treat the files as openvpn etc read/write content. openvpn_etc_t- Set files with the openvpn_etc_t type, if you want to store openvpn files in the /etc directories. openvpn_exec_t- Set files with the openvpn_exec_t type, if you want to transition an executable to the openvpn_t domain. openvpn_initrc_exec_t- Set files with the openvpn_initrc_exec_t type, if you want to transition an executable to the openvpn_initrc_t domain. openvpn_status_t- Set files with the openvpn_status_t type, if you want to treat the files as openvpn status data. openvpn_tmp_t- Set files with the openvpn_tmp_t type, if you want to store openvpn temporary files in the /tmp directories. openvpn_unconfined_script_exec_t- Set files with the openvpn_unconfined_script_exec_t type, if you want to transition an executable to the openvpn_unconfined_script_t domain. openvpn_var_lib_t- Set files with the openvpn_var_lib_t type, if you want to store the openvpn files under the /var/lib directory. openvpn_var_log_t- Set files with the openvpn_var_log_t type, if you want to treat the data as openvpn var log data, usually stored under the /var/log directory. openvpn_var_run_t- Set files with the openvpn_var_run_t type, if you want to store the openvpn files under the /run or /var/run directory.
Paths: /var/run/openvpn(/.*)?, /var/run/openvpn.client.*, /var/run/openvpn-server(/.*)? 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.
COMMANDSsemanage 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.
