One such structure is present for each VPN + * tunnel, and is stored in \c context.c2.fragment of the \c context + * associated with that VPN tunnel. + * + * @par + * The \c fragment_master structure contains one \c fragment_list + * structure \c fragment_master.incoming. This is a list of \c fragment + * structures, each of which can store the parts of one fragmented packet + * while it is being reassembled. The \c fragment_master structure also + * contains one \c buffer called \c fragment_master.outgoing, in which a + * data channel large packet to be sent to a remote OpenVPN peer can be + * broken up into parts to be sent one by one. + * + * @par Initialization and cleanup + * Every time a new \c fragment_master is needed, it must be allocated and + * initialized by the \c fragment_init() function. Similarly, every time + * a \c fragment_master is no longer needed, it must be cleaned up using + * the \c fragment_free() function. These functions take care of the + * allocation and freeing of the \c fragment_master structure itself and + * all internal memory required for the use of that structure. Note that + * this behavior is different from that displayed by the \link compression + * Data Channel Compression module\endlink. + * + * @par + * Because of the one-to-one relationship between \c fragment_master + * structures and VPN tunnels, the above-mentioned initialization and + * cleanup functions are called directly from the \c init_instance() and + * \c close_instance() functions, which control the initialization and + * cleanup of VPN tunnel instances and their associated \c context + * structures. + * + * @par Packet processing functions + * This module receives data channel packets from the \link data_control + * Data Channel Control module\endlink and processes them according to the + * settings of the packet's VPN tunnel. The \link data_control Data + * Channel Control module\endlink uses the following interface functions: + * - For packets which will be sent to a remote OpenVPN peer: \c + * fragment_outgoing() \n This function inspects data channel packets as + * they are being made ready to be sent as VPN tunnel packets to a + * remote OpenVPN peer. If a packet's size is larger than its + * destination VPN tunnel's maximum transmission unit (MTU), then this + * module breaks that packet up into smaller parts, each of which is + * smaller than or equal to the VPN tunnel's MTU. See \c + * fragment_outgoing() for details. + * - For packets which have been received from a remote OpenVPN peer: \c + * fragment_incoming() \n This function inspects data channel packets + * that have been received from a remote OpenVPN peer through a VPN + * tunnel. It reads the fragmentation header of the packet, and + * depending on its value performs the appropriate action. See \c + * fragment_incoming() for details. + * + * @par Settings that control this module's activity + * Whether the Data Channel Fragmentation module is active or not depends + * on the compile-time \c ENABLE_FRAGMENT preprocessor macro and the + * runtime flag \c options.fragment, which gets its value from the + * process's configuration sources, such as the configuration file and + * commandline %options. + */ -- cgit v1.2.3
