- *
- * RETURN VALUE
- *
- * OPENVPN_PLUGIN_FUNC_SUCCESS on success, OPENVPN_PLUGIN_FUNC_ERROR on failure
- *
- * In addition, OPENVPN_PLUGIN_FUNC_DEFERRED may be returned by
- * OPENVPN_PLUGIN_AUTH_USER_PASS_VERIFY.  This enables asynchronous
- * authentication where the plugin (or one of its agents) may indicate
- * authentication success/failure some number of seconds after the return
- * of the OPENVPN_PLUGIN_AUTH_USER_PASS_VERIFY handler by writing a single
- * char to the file named by auth_control_file in the environmental variable
- * list (envp).
- *
- * first char of auth_control_file:
- * '0' -- indicates auth failure
- * '1' -- indicates auth success
- *
- * OpenVPN will delete the auth_control_file after it goes out of scope.
- *
- * If an OPENVPN_PLUGIN_ENABLE_PF handler is defined and returns success
- * for a particular client instance, packet filtering will be enabled for that
- * instance.  OpenVPN will then attempt to read the packet filter configuration
- * from the temporary file named by the environmental variable pf_file.  This
- * file may be generated asynchronously and may be dynamically updated during the
- * client session, however the client will be blocked from sending or receiving
- * VPN tunnel packets until the packet filter file has been generated.  OpenVPN
- * will periodically test the packet filter file over the life of the client
- * instance and reload when modified.  OpenVPN will delete the packet filter file
- * when the client instance goes out of scope.
- *
- * Packet filter file grammar:
- *
- * [CLIENTS DROP|ACCEPT]
- * {+|-}common_name1
- * {+|-}common_name2
- * . . .
- * [SUBNETS DROP|ACCEPT]
- * {+|-}subnet1
- * {+|-}subnet2
- * . . .
- * [END]
- *
- * Subnet: IP-ADDRESS | IP-ADDRESS/NUM_NETWORK_BITS
- *
- * CLIENTS refers to the set of clients (by their common-name) which
- * this instance is allowed ('+') to connect to, or is excluded ('-')
- * from connecting to.  Note that in the case of client-to-client
- * connections, such communication must be allowed by the packet filter
- * configuration files of both clients.
- *
- * SUBNETS refers to IP addresses or IP address subnets which this
- * instance may connect to ('+') or is excluded ('-') from connecting
- * to.
- *
- * DROP or ACCEPT defines default policy when there is no explicit match
- * for a common-name or subnet.  The [END] tag must exist.  A special
- * purpose tag called [KILL] will immediately kill the client instance.
- * A given client or subnet rule applies to both incoming and outgoing
- * packets.
- *
- * See plugin/defer/simple.c for an example on using asynchronous
- * authentication and client-specific packet filtering.
