-/**
- * @defgroup compression Data Channel Compression module
- *
- * This module offers compression of data channel packets.
- *
- * @par State structures
- * The Data Channel Compression module stores its internal state in a \c
- * lzo_compress_workspace structure. This state includes flags which
- * control the module's behavior and preallocated working memory. One
- * such structure is present for each VPN tunnel, and is stored in the \c
- * context.c2.lzo_compwork of the \c context associated with that VPN
- * tunnel.
- *
- * @par Initialization and cleanup
- * Every time a new \c lzo_compress_workspace is needed, it must be
- * initialized using the \c lzo_compress_init() function. Similarly,
- * every time a \c lzo_compress_workspace is no longer needed, it must be
- * cleaned up using the \c lzo_compress_uninit() function. These
- * functions take care of the allocation and freeing of internal working
- * memory, but not of the \c lzo_compress_workspace structures themselves.
- *
- * @par
- * Because of the one-to-one relationship between \c
- * lzo_compress_workspace 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
- * lzo_compress()
- * - For packets which have been received from a remote OpenVPN peer: \c
- * lzo_decompress()
- *
- * @par Settings that control this module's activity
- * Whether or not the Data Channel Compression module is active depends on
- * the compile-time \c ENABLE_LZO preprocessor macro and the runtime flags
- * stored in \c lzo_compress_workspace.flags of the associated VPN tunnel.
- * The latter are initialized from \c options.lzo, which gets its value
- * from the process's configuration sources, such as its configuration
- * file or command line %options.
- *
- * @par Adaptive compression
- * The compression module supports adaptive compression. If this feature
- * is enabled, the compression routines monitor their own performance and
- * turn compression on or off depending on whether it is leading to
- * significantly reduced payload size.
- *
- * @par Compression algorithms
- * This module uses the Lempel-Ziv-Oberhumer (LZO) compression algorithms.
- * These offer lossless compression and are designed for high-performance
- * decompression. This module uses the external \c lzo library's
- * implementation of the algorithms.
- *
- * @par
- * For more information on the LZO library, see:\n
- * http://www.oberhumer.com/opensource/lzo/

-/**
- * @defgroup control_processor Control Channel Processor module
- *
- * This module controls the setup and maintenance of VPN tunnels and the
- * associated security parameters.
- *
- * @par This module's role
- * The Control Channel Processor module lies at the core of OpenVPN's
- * activities. It handles the setup of new VPN tunnels, the negotiation
- * of data channel security parameters, the managing of active VPN
- * tunnels, and finally the cleanup of expired VPN tunnels.
- *
- * @par State structures
- * A large amount of VPN tunnel state information must be stored within an
- * OpenVPN process. A wide variety of container structures are used by
- * this module for that purpose. Several of these structures are listed
- * below, and the function of the first three VPN tunnel state containers
- * is described in more detail later.
- * - VPN tunnel state containers:
- * - \c tls_multi, security parameter state for a single VPN tunnel.
- * Contains three instances of the \c tls_session structure.
- * - \c tls_session, security parameter state of a single session
- * within a VPN tunnel. Contains two instances of the \c key_state
- * structure.
- * - \c key_state, security parameter state of one TLS and data
- * channel %key set.
- * - Data channel security parameter containers:
- * - \c key_ctx_bi, container for two sets of OpenSSL cipher and/or
- * HMAC context (both directions). Contains two instances of the \c
- * key_ctx structure.
- * - \c key_ctx, container for one set of OpenSSL cipher and/or HMAC
- * context (one directions.
- * - Key material containers:
- * - \c key2, container for two sets of cipher and/or HMAC %key
- * material (both directions). Contains two instances of the \c key
- * structure.
- * - \c key, container for one set of cipher and/or HMAC %key material
- * (one direction).
- * - \c key_direction_state, ordering of %key material within the \c
- * key2.key array.
- * - Key method 2 random material containers:
- * - \c key_source2, container for both halves of random material used
- * for %key method 2. Contains two instances of the \c key_source
- * structure.
- * - \c key_source, container for one half of random material used for
- * %key method 2.
- *
- * @par The life of a \c tls_multi object
- * A \c tls_multi structure contains all the security parameter state
- * information related to the control and data channels of one VPN tunnel.
- * Its life cycle can be summarized as follows:
- * -# Initialization: \c tls_multi_init() and \c
- * tls_multi_init_finalize(), which are called (indirectly) from \c
- * init_instance() when initializing a new \c context structure.
- * - Initializes a \c tls_multi structure.
- * - Allocates the three \c tls_session objects contained by the \c
- * tls_multi structure, and initializes as appropriate.
- * -# Management: \c tls_multi_process() and \c tls_pre_decrypt()
- * - If a new session is initiated by the remote peer, then \c
- * tls_pre_decrypt() starts the new session negotiation in the
- * un-trusted \c tls_session.
- * - If the, as yet, un-trusted \c tls_session authenticates
- * successfully, then \c tls_multi_process() moves it so as to be
- * the active \c tls_session.
- * - If an error occurs during processing of a \c key_state object,
- * then \c tls_multi_process() cleans up and initializes the
- * associated \c tls_session object. If the error occurred in the
- * active \c key_state of the active \c tls_session and the
- * lame-duck \c key_state of that \c tls_session has not yet
- * expired, it is preserved as fallback.
- * -# Cleanup: \c tls_multi_free(), which is called (indirectly) from \c
- * close_instance() when cleaning up a \c context structure.
- * - Cleans up a \c tls_multi structure.
- * - Cleans up the three \c tls_session objects contained by the \c
- * tls_multi structure.
- *
- * @par The life of a \c tls_session object
- * A \c tls_session structure contains the state information related to an
- * active and a lame-duck \c key_state. Its life cycle can be summarized
- * as follows:
- * -# Initialization: \c tls_session_init()
- * - Initializes a \c tls_session structure.
- * - Initializes the primary \c key_state by calling \c
- * key_state_init().
- * -# Renegotiation: \c key_state_soft_reset()
- * - Cleans up the old lame-duck \c key_state by calling \c
- * key_state_free().
- * - Moves the old primary \c key_state to be the new lame-duck \c
- * key_state.
- * - Initializes a new primary \c key_state by calling \c
- * key_state_init().
- * -# Cleanup: \c tls_session_free()
- * - Cleans up a \c tls_session structure.
- * - Cleans up all \c key_state objects associated with the session by
- * calling \c key_state_free() for each.
- *
- * @par The life of a \c key_state object
- * A \c key_state structure represents one control and data channel %key
- * set. It contains an OpenSSL TLS object that encapsulates the control
- * channel, and the data channel security parameters needed by the \link
- * data_crypto Data Channel Crypto module\endlink to perform cryptographic
- * operations on data channel packets. Its life cycle can be summarized
- * as follows:
- * -# Initialization: \c key_state_init()
- * - Initializes a \c key_state structure.
- * - Creates a new OpenSSL TLS object to encapsulate this new control
- * channel session.
- * - Sets \c key_state.state to \c S_INITIAL.
- * - Allocates several internal buffers.
- * - Initializes new reliability layer structures for this key set.
- * -# Negotiation: \c tls_process()
- * - The OpenSSL TLS object negotiates a TLS session between itself
- * and the remote peer's TLS object.
- * - Key material is generated and exchanged through the TLS session
- * between OpenVPN peers.
- * - Both peers initialize their data channel cipher and HMAC key
- * contexts.
- * - On successful negotiation, the \c key_state.state will progress
- * from \c S_INITIAL to \c S_ACTIVE and \c S_NORMAL.
- * -# Active tunneling: \link data_crypto Data Channel Crypto
- * module\endlink
- * - Data channel packet to be sent to a remote OpenVPN peer:
- * - \c tls_pre_encrypt() loads the security parameters from the \c
- * key_state into a \c crypto_options structure.
- * - \c openvpn_encrypt() uses the \c crypto_options to an encrypt
- * and HMAC sign the data channel packet.
- * - Data channel packet received from a remote OpenVPN peer:
- * - \c tls_pre_decrypt() loads the security parameters from the \c
- * key_state into a \c crypto_options structure.
- * - \c openvpn_encrypt() uses the \c crypto_options to
- * authenticate and decrypt the data channel packet.
- * -# Cleanup: \c key_state_free()
- * - Cleans up a \c key_state structure together with its OpenSSL TLS
- * object, key material, internal buffers, and reliability layer
- * structures.
- *
- * @par Control functions
- * The following two functions drive the Control Channel Processor's
- * activities.
- * - \c tls_multi_process(), iterates through the \c tls_session objects
- * within a given \c tls_multi of a VPN tunnel, and calls \c
- * tls_process() for each \c tls_session which is being set up, is
- * already active, or is busy expiring.
- * - \c tls_process(), performs the Control Channel Processor module's
- * core handling of received control channel messages, and generates
- * appropriate messages to be sent.
- *
- * @par Functions which control data channel key generation
- * - Key method 1 key exchange functions:
- * - \c key_method_1_write(), generates and processes key material to
- * be sent to the remote OpenVPN peer.
- * - \c key_method_1_read(), processes key material received from the
- * remote OpenVPN peer.
- * - Key method 2 key exchange functions:
- * - \c key_method_2_write(), generates and processes key material to
- * be sent to the remote OpenVPN peer.
- * - \c key_method_2_read(), processes key material received from the
- * remote OpenVPN peer.

-/**
- * @defgroup control_tls Control Channel TLS module
- *
- * This module provides secure encapsulation of control channel messages
- * exchanged between OpenVPN peers.
- *
- * The Control Channel TLS module uses the Transport Layer Security (TLS)
- * protocol to provide an encrypted communication channel between the
- * local OpenVPN process and a remote peer. This protocol simultaneously
- * offers certificate-based authentication of the communicating parties.
- *
- * @par This module's roles
- * The Control Channel TLS module is essential for the security of any
- * OpenVPN-based system. On the one hand, it performs the security
- * operations necessary to protect control channel messages exchanged
- * between OpenVPN peers. On the other hand, before the control and data
- * channels are even setup, it controls the exchange of certificates and
- * verification of the remote's identity during negotiation of VPN
- * tunnels.
- *
- * @par
- * The former role is described below. The latter is described in the
- * documentation for the \c verify_callback() function.
- *
- * @par
- * In other words, this module takes care of the confidentiality and
- * integrity of data channel communications, and the authentication of
- * both the communicating parties and the control channel messages
- * exchanged.
- *
- * @par Initialization and cleanup
- * Because of the one-to-one relationship between control channel TLS
- * state and \c key_state structures, the initialization and cleanup of an
- * instance of the Control Channel TLS module's state happens within the
- * \c key_state_init() and \c key_state_free() functions. In other words,
- * each \c key_state object contains exactly one OpenSSL SSL-BIO object,
- * which is initialized and cleaned up together with the rest of the \c
- * key_state object.
- *
- * @par Packet processing functions
- * This object behaves somewhat like a black box with a ciphertext and a
- * plaintext I/O port. Its interaction with OpenVPN's control channel
- * during operation takes place within the \c tls_process() function of
- * the \link control_processor Control Channel Processor\endlink. The
- * following functions are available for processing packets:
- * - If ciphertext received from the remote peer is available in the \link
- * reliable Reliability Layer\endlink:
- * - Insert it into the ciphertext-side of the SSL-BIO.
- * - Use function: \c key_state_write_ciphertext()
- * - If ciphertext can be extracted from the ciphertext-side of the
- * SSL-BIO:
- * - Pass it to the \link reliable Reliability Layer\endlink for sending
- * to the remote peer.
- * - Use function: \c key_state_read_ciphertext()
- * - If plaintext can be extracted from the plaintext-side of the SSL-BIO:
- * - Pass it on to the \link control_processor Control Channel
- * Processor\endlink for local processing.
- * - Use function: \c key_state_read_plaintext()
- * - If plaintext from the \link control_processor Control Channel
- * Processor\endlink is available to be sent to the remote peer:
- * - Insert it into the plaintext-side of the SSL-BIO.
- * - Use function: \c key_state_write_plaintext() or \c
- * key_state_write_plaintext_const()
- *
- * @par Transport Layer Security protocol implementation
- * This module uses the OpenSSL library's implementation of the TLS
- * protocol in the form of an OpenSSL SSL-BIO object.
- *
- * @par
- * For more information on the OpenSSL library's BIO objects, please see:
- * - OpenSSL's generic BIO objects:

- *
- * This module controls the processing of packets as they pass through the
- * data channel.
- *
- * The Data Channel Control module controls the processing of packets as
- * they pass through the data channel. The processing includes packet
- * compression, fragmentation, and the performing of security operations
- * on the packets. This module does not do the processing itself, but
- * passes the packet to other data channel modules to perform the
- * appropriate actions.
- *
- * Packets can travel in two directions through the data channel. They
- * can be going to a remote destination which is reachable through a VPN
- * tunnel, in which case this module prepares them to be sent out through
- * a VPN tunnel. On the other hand, they can have been received through a
- * VPN tunnel from a remote OpenVPN peer, in which case this module
- * retrieves the packet in its original form as it was before entering the
- * VPN tunnel on the remote OpenVPN peer. How this module processes
- * packets traveling in the two directions is discussed in more detail
- * below.
- *
- * @par Packets to be sent to a remote OpenVPN peer
- * This module's main function for processing packets traveling in this
- * direction is \c encrypt_sign(), which performs the following processing
- * steps:
- * - Call the \link compression Data Channel Compression module\endlink to
- * perform packet compression if necessary.
- * - Call the \link fragmentation Data Channel Fragmentation
- * module\endlink to perform packet fragmentation if necessary.
- * - Call the \link data_crypto Data Channel Crypto module\endlink to
- * perform the required security operations.
- *
- * @par
- * See the \c encrypt_sign() documentation for details of these
- * interactions.
- *
- * @par
- * After the above processing is complete, the packet is ready to be sent
- * to a remote OpenVPN peer as a VPN tunnel packet. The actual sending of
- * the packet is handled by the \link external_multiplexer External
- * Multiplexer\endlink.
- *
- * @par Packets received from a remote OpenVPN peer
- * The function that controls how packets traveling in this direction are
- * processed is \c process_incoming_link(). That function, however, also
- * performs some of the tasks required for the \link external_multiplexer
- * External Multiplexer\endlink and is therefore listed as part of that
- * module, instead of here.
- *
- * @par
- * After the \c process_incoming_link() function has determined that a
- * received packet is a data channel packet, it performs the following
- * processing steps:
- * - Call the \link data_crypto Data Channel Crypto module\endlink to
- * perform the required security operations.
- * - Call the \link fragmentation Data Channel Fragmentation
- * module\endlink to perform packet reassembly if necessary.
- * - Call the \link compression Data Channel Compression module\endlink to
- * perform packet decompression if necessary.
- *
- * @par
- * See the \c process_incoming_link() documentation for details of these
- * interactions.
- *
- * @par
- * After the above processing is complete, the packet is in its original
- * form again as it was received by the remote OpenVPN peer. It can now
- * be routed further to its final destination. If that destination is a
- * locally reachable host, then the \link internal_multiplexer Internal
- * Multiplexer\endlink will send it there.

- * data channel packets.
- *
- * @par Security parameters
- * This module is merely the user of a VPN tunnel's security parameters.
- * It does not perform the negotiation and setup of the security
- * parameters, nor the %key generation involved. These actions are done
- * by the \link control_processor Control Channel Processor\endlink. This
- * module receives the appropriate security parameters from that module in
- * the form of a \c crypto_options structure when they are necessary for
- * processing a packet.
- *
- * @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
- * security parameters 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 tls_pre_encrypt()
- * - \c openvpn_encrypt()
- * - \c tls_post_encrypt()
- * - For packets which have been received from a remote OpenVPN peer:
- * - \c tls_pre_decrypt() (documented as part of the \link
- * external_multiplexer External Multiplexer\endlink)
- * - \c openvpn_decrypt()
- *
- * @par Settings that control this module's activity
- * Whether or not the Data Channel Crypto module is active depends on the
- * compile-time \c ENABLE_CRYPTO and \c ENABLE_SSL preprocessor macros. How it
- * processes packets received from the \link data_control Data Channel
- * Control module\endlink at runtime depends on the associated \c
- * crypto_options structure. To perform cryptographic operations, the \c
- * crypto_options.key_ctx_bi must contain the correct cipher and HMAC
- * security parameters for the direction the packet is traveling in.
- *
- * @par Crypto algorithms
- * This module uses the crypto algorithm implementations of the external
- * OpenSSL library. More precisely, it uses the OpenSSL library's \c
- * EVP_Cipher* and \c HMAC_* set of functions to perform cryptographic
- * operations on data channel packets.

-/**
- * @defgroup eventloop Main Event Loop module
- *
- * This main event loop module drives the packet processing of OpenVPN.
- *
- * OpenVPN is an event driven system. Its activities are driven by a main
- * event loop, which repeatedly waits for one of several predefined events
- * to occur, and then calls the appropriate module to handle the event.
- * The major types of network events that OpenVPN processes are:
- * - A packet can be read from the external network interface.
- * - The main event loop activates the \link external_multiplexer
- * External Multiplexer\endlink to read and process the packet.
- * - A packet can be read from the virtual tun/tap network interface.
- * - The main event loop activates the \link internal_multiplexer
- * Internal Multiplexer\endlink to read and process the packet.
- * - If a packet is ready to be sent out as a VPN tunnel packet: the
- * external network interface can be written to.
- * - The main event loop activates the \link external_multiplexer
- * External Multiplexer\endlink to send the packet.
- * - If a packet is ready to be sent to a locally reachable destination:
- * the virtual tun/tap network interface can be written to.
- * - The main event loop activates the \link internal_multiplexer
- * Internal Multiplexer\endlink to send the packet.
- *
- * Beside these external events, OpenVPN also processes other types of
- * internal events. These include scheduled events, such as resending of
- * non-acknowledged control channel messages.
- *
- * @par Main event loop implementations
- *
- * Depending on the mode in which OpenVPN is running, a different main
- * event loop function is called to drive the event processing. The
- * following implementations are available:
- * - Client mode using UDP or TCP: \c tunnel_point_to_point()
- * - Server mode using UDP: \c tunnel_server_udp_single_threaded()
- * - Server mode using TCP: \c tunnel_server_tcp()

-/**
- * @defgroup fragmentation Data Channel Fragmentation module
- *
- * The Data Channel Fragmentation module offers fragmentation of data
- * channel packets.
- *
- * @par State structures
- * The Data Channel Fragmentation module stores its internal state in a \c
- * fragment_master structure. 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.

-
-/**
- * @page key_generation Data channel %key generation
- *
- * This section describes how OpenVPN peers generate and exchange %key
- * material necessary for the security operations performed on data
- * channel packets.
- *
- * The %key generation and exchange process between OpenVPN client and
- * server occurs every time data channel security parameters are
- * negotiated, for example during the initial setup of a VPN tunnel or
- * when the active security parameters expire. In source code terms, this
- * is when a new key_state structure is initialized.
- *
- * @section key_generation_method Key methods
- *
- * OpenVPN supports two different ways of generating and exchanging %key
- * material between client and server. These are known as %key method 1
- * and %key method 2. %Key method 2 is the recommended method. Both are
- * explained below.
- *
- * @subsection key_generation_method_1 Key method 1
- *
- * -# Each host generates its own random material.
- * -# Each host uses its locally generated random material as %key data
- * for encrypting and signing packets sent to the remote peer.
- * -# Each host then sends its random material to the remote peer, so that
- * the remote peer can use that %key data for authenticating and
- * decrypting received packets.
- *
- * @subsection key_generation_method_2 Key method 2
- *
- * -# The client generates random material in the following amounts:
- * - Pre-master secret: 48 bytes
- * - Client's PRF seed for master secret: 32 bytes
- * - Client's PRF seed for %key expansion: 32 bytes
- * -# The client sends its share of random material to the server.
- * -# The server generates random material in the following amounts:
- * - Server's PRF seed for master secret: 32 bytes
- * - Server's PRF seed for %key expansion: 32 bytes
- * -# The server computes the %key expansion using its own and the
- * client's random material.
- * -# The server sends its share of random material to the client.
- * -# The client computes the %key expansion using its own and the
- * server's random material.
- *
- * %Key method 2 %key expansion is performed by the \c
- * generate_key_expansion() function. Please refer to its source code for
- * details of the %key expansion process.
- *
- * @subsection key_generation_random Source of random material
- *
- * OpenVPN uses the either the OpenSSL library or the PolarSSL library as its
- * source of random material.
- *
- * In OpenSSL, the \c RAND_bytes() function is called
- * to supply cryptographically strong pseudo-random data. The following links
- * contain more information on this subject:
- * - For OpenSSL's \c RAND_bytes() function:
- * http://www.openssl.org/docs/crypto/RAND_bytes.html
- * - For OpenSSL's pseudo-random number generating system:
- * http://www.openssl.org/docs/crypto/rand.html
- * - For OpenSSL's support for external crypto modules:
- * http://www.openssl.org/docs/crypto/engine.html
- *
- * In PolarSSL, the Havege random number generator is used. For details, see
- * the PolarSSL documentation.
- *
- * @section key_generation_exchange Key exchange:
- *
- * The %key exchange process is initiated by the OpenVPN process running
- * in client mode. After the initial three-way handshake has successfully
- * completed, the client sends its share of random material to the server,
- * after which the server responds with its part. This process is
- * depicted below:
- *
-@verbatim
- Client Client Server Server
- State Action Action State
----------- -------------------- -------------------- ----------
-
- ... waiting until three-way handshake complete ...
-S_START S_START
- key_method_?_write()
- send to server --> --> --> --> receive from client
-S_SENT_KEY key_method_?_read()
- S_GOT_KEY
- key_method_?_write()
- receive from server <-- <-- <-- <-- send to client
- key_method_?_read() S_SENT_KEY
-S_GOT_KEY
- ... waiting until control channel fully synchronized ...
-S_ACTIVE S_ACTIVE
-@endverbatim
- *
- * For more information about the client and server state values, see the
- * \link control_processor Control Channel Processor module\endlink.
- *
- * Depending on which %key method is used, the \c ? in the function names
- * of the diagram above is a \c 1 or a \c 2. For example, if %key method
- * 2 is used, that %key exchange would be started by the client calling \c
- * key_method_2_write(). These functions are called from the \link
- * control_processor Control Channel Processor module's\endlink \c
- * tls_process() function and control the %key generation and exchange
- * process as follows:
- * - %Key method 1:
- * - \c key_method_1_write(): generate random material locally, and load
- * as "sending" keys.
- * - \c key_method_1_read(): read random material received from remote
- * peer, and load as "receiving" keys.
- * - %Key method 2:
- * - \c key_method_2_write(): generate random material locally, and if
- * in server mode generate %key expansion.
- * - \c key_method_2_read(): read random material received from remote
- * peer, and if in client mode generate %key expansion.
- *
- * @subsection key_generation_encapsulation Transmission of key material
- *
- * The OpenVPN client and server communicate with each other through their
- * control channel. This means that all of the data transmitted over the
- * network, such as random material for %key generation, is encapsulated
- * in a TLS layer. For more details, see the \link control_tls Control
- * Channel TLS module\endlink documentation.

-/**
- * @mainpage OpenVPN v2.1 source code documentation
- *
- * This documentation describes the internal structure of OpenVPN. It was
- * automatically generated from specially formatted comment blocks in
- * OpenVPN's source code using Doxygen. (See
- * http://www.stack.nl/~dimitri/doxygen/ for more information on Doxygen)
- *
- * The \ref mainpage_modules "Modules section" below gives an introduction
- * into the high-level module concepts used throughout this documentation.
- * The \ref mainpage_relatedpages "Related Pages section" below describes
- * various special subjects related to OpenVPN's implementation which are
- * discussed in the related pages section.
- *
- * @section mainpage_modules Modules
- *
- * For the purpose of describing the internal structure of OpenVPN, this
- * documentation and the underlying source code has been broken up into a
- * number of conceptually well-defined parts, known as modules. Each
- * module plays a specific role within the OpenVPN process, and in most
- * cases each module has a clear interfacing strategy for interacting with
- * other modules.
- *
- * The following modules have been defined:
- * - Driver module:
- * - The \link eventloop Main Event Loop\endlink: this module drives the
- * event handling of OpenVPN. It implements various types of
- * select-loop which wait until an event happens, and then delegate
- * the handling of that event to the appropriate module.
- * - Network interface modules:
- * - The \link external_multiplexer External Multiplexer\endlink: this
- * module sends and receives packets to and from remote OpenVPN peers
- * over the external network interface. It also takes care of
- * demultiplexing received packets to their appropriate VPN tunnel and
- * splitting control channel and data channel packets.
- * - The \link internal_multiplexer Internal Multiplexer\endlink: this
- * module sends and receives packets to and from locally reachable
- * posts over the virtual tun/tap network interface. It also takes
- * care of determining through which VPN tunnel a received packet must
- * be sent to reach its destination.
- * - Control channel modules:
- * - The \link reliable Reliability Layer\endlink: this module offers a
- * %reliable and sequential transport layer for control channel
- * messages.
- * - The \link control_tls Control Channel TLS module\endlink: this
- * module offers a secure encapsulation of control channel messages
- * using the TLS protocol.
- * - The \link control_processor Control Channel Processor\endlink: his
- * module manages the setup, maintenance, and shut down of VPN
- * tunnels.
- * - Data channel modules:
- * - The \link data_control Data Channel Control module\endlink: this
- * module controls the processing of data channel packets and,
- * depending on the settings of the packet's VPN tunnel, passes the
- * packet to the three modules below for handling.
- * - The \link data_crypto Data Channel Crypto module\endlink: this
- * module performs security operations on data channel packets.
- * - The \link fragmentation Data Channel Fragmentation module\endlink:
- * this module offers fragmentation of data channel packets larger
- * than the VPN tunnel's MTU.
- * - The \link compression Data Channel Compression module\endlink: this
- * module offers compression of data channel packets.
- *
- * @subsection mainpage_modules_example Example event: receiving a packet
- *
- * OpenVPN handles many types of events during operation. These include
- * external events, such as network traffic being received, and internal
- * events, such as a %key session timing out causing renegotiation. An
- * example event, receiving a packet over the network, is described here
- * together with which modules play what roles:
- * -# The \link eventloop Main Event Loop\endlink detects that a packet
- * can be read from the external or the virtual tun/tap network
- * interface.
- * -# The \link eventloop Main Event Loop\endlink calls the \link
- * external_multiplexer External Multiplexer\endlink or \link
- * internal_multiplexer Internal Multiplexer\endlink to read and
- * process the packet.
- * -# The multiplexer module determines the type of packet and its
- * destination, and passes the packet on to the appropriate handling
- * module:
- * - A control channel packet received by the \link
- * external_multiplexer External Multiplexer\endlink is passed on
- * through the \link reliable Reliability Layer\endlink and the \link
- * control_tls Control Channel TLS module\endlink to the \link
- * control_processor Control Channel Processor\endlink.
- * - A data channel packet received by either multiplexer module is
- * passed on to the \link data_control Data Channel Control
- * module\endlink.
- * -# The packet is processed by the appropriate control channel or data
- * channel modules.
- * -# If, after processing the packet, a resulting packet is generated
- * that needs to be sent to a local or remote destination, it is given
- * to the \link external_multiplexer External Multiplexer\endlink or
- * \link internal_multiplexer Internal Multiplexer\endlink for sending.
- * -# If a packet is waiting to be sent by either multiplexer module and
- * the \link eventloop Main Event Loop\endlink detects that data can be
- * written to the associated network interface, it calls the
- * multiplexer module to send the packet.
- *
- * @section mainpage_relatedpages Related pages
- *

-/**
- * @page memory_management OpenVPN's memory management strategies
- *
- * This section describes several implementation details relating to
- * OpenVPN's memory management strategies.
- *
- * During operation, the OpenVPN process performs all kinds of operations
- * on blocks of data. Receiving packets, encrypting content, prepending
- * headers, etc. To make the programmer's job easier and to decrease the
- * likelihood of memory-related bugs, OpenVPN uses its own memory %buffer
- * library and garbage collection facilities. These are described in
- * brief here.
- *
- * @section memory_management_buffer The buffer structure
- *
- * The \c buffer structure is a wrapper around a block of dynamically
- * allocated memory which keeps track of the block's capacity \c
- * buffer.capacity and location in memory \c buffer.data. This structure
- * supports efficient prepending and appending within the allocated memory
- * through the use of offset \c buffer.offset and length \c buffer.len
- * fields. See the \c buffer documentation for more details on the
- * structure itself.
- *
- * OpenVPN's %buffer library, implemented in the \c buffer.h and \c
- * buffer.c files, contains many utility functions for working with \c
- * buffer structures. These functions facilitate common operations, such
- * as allocating, freeing, reading and writing to \c buffer structures,
- * and even offer several more advanced operations, such as string
- * matching and creating sub-buffers.
- *
- * Not only do these utility functions make working with \c buffer
- * structures easy, they also perform extensive error checking. Each
- * function, where necessary, checks whether enough space is available
- * before performing its actions. This minimizes the chance of bugs
- * leading to %buffer overflows and other vulnerabilities.
- *
- * @section memory_management_frame The frame structure
- *
- * The \c frame structure keeps track of the maximum allowed packet
- * geometries of a network connection.
- *
- * It is used, for example, to determine the size of \c buffer structures
- * in which to store data channel packets. This is done by having each
- * data channel processing module register the maximum amount of extra
- * space it will need for header prepending and content expansion in the
- * \c frame structure. Once these parameters are known, \c buffer
- * structures can be allocated, based on the \c frame parameters, so that
- * they are large enough to allow efficient prepending of headers and
- * processing of content.
- *
- * @section memory_management_garbage Garbage collection
- *
- * OpenVPN has many sizable functions which perform various actions
- * depending on their %context. This makes it difficult to know in advance
- * exactly how much memory must be allocated. The garbage collection
- * facilities are used to keep track of dynamic allocations, thereby
- * allowing easy collective freeing of the allocated memory.
- *
- * The garbage collection system is implemented by the \c gc_arena and \c
- * gc_entry structures. The arena represents a garbage collecting unit,
- * and contains a linked list of entries. Each entry represents one block
- * of dynamically allocated memory.
- *
- * The garbage collection system also contains various utility functions
- * for working with the garbage collection structures. These include
- * functions for initializing new arenas, allocating memory of a given
- * size and registering the allocation in an arena, and freeing all the
- * allocated memory associated with an arena.

- * @page network_protocol OpenVPN's network protocol
- *
- * Description of packet structure in OpenVPN's network protocol.
- *
- * This document describes the structure of packets exchanged between
- * OpenVPN peers. It is based on the protocol description in the \c ssl.h
- * file.
- *
- * @section network_protocol_external Outer structure of packets exchanged between OpenVPN peers
- *
- * VPN tunnel packets are transported between OpenVPN peers using the UDP
- * or TCP protocols. Their structure is described below.
- *
- * @subsection network_protocol_external_structure External packet structure
- *
- * - packet length (16 bits, unsigned) [TCP-mode only]: always sent as
- * plain text. Since TCP is a stream protocol, this packet length
- * defines the packetization of the stream.
- * - packet opcode and key_id (8 bits) [TLS-mode only]:
- * - package message type (high 5 bits)
- * - key_id (low 3 bits): the key_id refers to an already negotiated
- * TLS session. OpenVPN seamlessly renegotiates the TLS session by
- * using a new key_id for the new session. Overlap (controlled by
- * user definable parameters) between old and new TLS sessions is
- * allowed, providing a seamless transition during tunnel operation.
- * - payload (n bytes)
- *
- * @subsection network_protocol_external_types Message types
- *
- * The type of a VPN tunnel packet is indicated by its opcode. The
- * following describes the various opcodes available.
- *
- * - Control channel messages:
- * - \c P_CONTROL_HARD_RESET_CLIENT_V1 -- %Key method 1, initial %key
- * from client, forget previous state.
- * - \c P_CONTROL_HARD_RESET_SERVER_V1 -- %Key method 1, initial %key
- * from server, forget previous state.
- * - \c P_CONTROL_HARD_RESET_CLIENT_V2 -- %Key method 2, initial %key
- * from client, forget previous state.
- * - \c P_CONTROL_HARD_RESET_SERVER_V2 -- %Key method 2, initial %key
- * from server, forget previous state.
- * - \c P_CONTROL_SOFT_RESET_V1 -- New %key, with a graceful
- * transition from old to new %key in the sense that a transition
- * window exists where both the old or new key_id can be used.
- * - \c P_CONTROL_V1 -- Control channel packet (usually TLS
- * ciphertext).
- * - \c P_ACK_V1 -- Acknowledgement for control channel packets
- * received.
- * - Data channel messages:
- * - \c P_DATA_V1 -- Data channel packet containing data channel
- * ciphertext.
- *
- * @subsection network_protocol_external_key_id Session IDs and Key IDs
- *
- * OpenVPN uses two different forms of packet identifiers:
- * - The first form is 64 bits and is used for all control channel
- * messages. This form is referred to as a \c session_id.
- * - Data channel messages on the other hand use a shortened form of 3
- * bits for efficiency reasons since the vast majority of OpenVPN
- * packets in an active tunnel will be data channel messages. This
- * form is referred to as a \c key_id.
- *
- * The control and data channels use independent packet-id sequences,
- * because the data channel is an unreliable channel while the control
- * channel is a %reliable channel. Each use their own independent HMAC
- * keys.
- *
- * @subsection network_protocol_external_reliable Control channel reliability layer
- *
- * Control channel messages (\c P_CONTROL_* and \c P_ACK_* message types)
- * are TLS ciphertext packets which have been encapsulated inside of a
- * reliability layer. The reliability layer is implemented as a
- * straightforward acknowledge and retransmit model.
- *
- * Acknowledgments of received messages can be encoded in either the
- * dedicated \c P_ACK_* record or they can be prepended to a \c
- * P_CONTROL_* message.
- *
- * See the \link reliable Reliability Layer\endlink module for a detailed
- * description.
- *
- * @section network_protocol_control Structure of control channel messages
- *
- * @subsection network_protocol_control_ciphertext Structure of ciphertext control channel messages
- *
- * Control channel packets in ciphertext form consist of the following
- * parts:
- *
- * - local \c session_id (random 64 bit value to identify TLS session).
- * - HMAC signature of entire encapsulation header for HMAC firewall
- * [only if \c --tls-auth is specified] (usually 16 or 20 bytes).
- * - packet-id for replay protection (4 or 8 bytes, includes sequence
- * number and optional \c time_t timestamp).
- * - acknowledgment packet-id array length (1 byte).
- * - acknowledgment packet-id array (if length > 0).
- * - acknowledgment remote session-id (if length > 0).
- * - packet-id of this message (4 bytes).
- * - TLS payload ciphertext (n bytes) (only for \c P_CONTROL_V1).
- *
- * Note that when \c --tls-auth is used, all message types are protected
- * with an HMAC signature, even the initial packets of the TLS handshake.
- * This makes it easy for OpenVPN to throw away bogus packets quickly,
- * without wasting resources on attempting a TLS handshake which will
- * ultimately fail.
- *
- * @subsection network_protocol_control_key_methods Control channel key methods and
- *
- * Once the TLS session has been initialized and authenticated, the TLS
- * channel is used to exchange random %key material for bidirectional
- * cipher and HMAC keys which will be used to secure data channel packets.
- * OpenVPN currently implements two %key methods. %Key method 1 directly
- * derives keys using random bits obtained from the \c RAND_bytes()
- * OpenSSL function. %Key method 2 mixes random %key material from both
- * sides of the connection using the TLS PRF mixing function. %Key method
- * 2 is the preferred method and is the default for OpenVPN 2.0.
- *
- * The @ref key_generation "Data channel key generation" related page
- * describes the %key methods in more detail.
- *
- * @subsection network_protocol_control_plaintext Structure of plaintext control channel messages
- *
- * - %Key method 1:
- * - Cipher %key length in bytes (1 byte).
- * - Cipher %key (n bytes).
- * - HMAC %key length in bytes (1 byte).
- * - HMAC %key (n bytes).
- * - %Options string (n bytes, null terminated, client/server %options
- * string should match).
- * - %Key method 2:
- * - Literal 0 (4 bytes).
- * - %Key method (1 byte).
- * - \c key_source structure (\c key_source.pre_master only defined
- * for client -> server).
- * - %Options string length, including null (2 bytes).
- * - %Options string (n bytes, null terminated, client/server %options
- * string must match).
- * - [The username/password data below is optional, record can end at
- * this point.]
- * - Username string length, including null (2 bytes).
- * - Username string (n bytes, null terminated).
- * - Password string length, including null (2 bytes).
- * - Password string (n bytes, null terminated).
- *
- * @section network_protocol_data Structure of data channel messages
- *
- * @subsection network_protocol_data_ciphertext Structure of ciphertext data channel messages
- *
- * The P_DATA_* payload represents encrypted, encapsulated tunnel packets
- * which tend to be either IP packets or Ethernet frames. This is
- * essentially the "payload" of the VPN.
- *
- * Data channel packets in ciphertext form consist of the following parts:
- * - HMAC of ciphertext IV + ciphertext (if not disabled by \c --auth
- * none).
- * - Ciphertext IV (size is cipher-dependent, if not disabled by \c
- * --no-iv).
- * - Tunnel packet ciphertext.
- *
- * @subsection network_protocol_data_plaintext Structure of plaintext data channel messages
- *
- * Data channel packets in plaintext form consist of the following parts:
- * - packet-id (4 or 8 bytes, if not disabled by --no-replay).
- * - In TLS mode, 4 bytes are used because the implementation can
- * force a TLS renegotation before \c 2^32 packets are sent.
- * - In pre-shared %key mode, 8 bytes are used (sequence number and \c
- * time_t value) to allow long-term %key usage without packet-id
- * collisions.
- * - User plaintext (n bytes).

-/**
- * @page tunnel_state Structure of the VPN tunnel state storage
- *
- * This section describes how OpenVPN stores its VPN tunnel state during
- * operation.
- *
- * OpenVPN uses several data structures as storage containers for state
- * information of active VPN tunnels. These are described in this
- * section, together with a little bit of history to help understand the
- * origin of the current architecture.
- *
- * Whether an OpenVPN process is running in client-mode or server-mode
- * determines whether it can support only one or multiple simultaneously
- * active VPN tunnels. This consequently also determines how the
- * associated state information is wrapped up internally. This section
- * gives an overview of the differences.
- *
- * @section tunnel_state_history Historic developments
- *
- * In the old v1.x series, an OpenVPN process managed only one single VPN
- * tunnel. This allowed the VPN tunnel state to be stored together with
- * process-global information in one single \c context structure.
- *
- * This changed, however, in the v2.x series, as new OpenVPN versions
- * running in server-mode can support multiple simultaneously active VPN
- * tunnels. This necessitated a redesign of the VPN tunnel state
- * container structures, and modification of the \link
- * external_multiplexer External Multiplexer\endlink and \link
- * internal_multiplexer Internal Multiplexer\endlink systems. The
- * majority of these changes are only relevant for OpenVPN processes
- * running in server-mode, and the client-mode structure has remained very
- * similar to the v1.x single-tunnel form.
- *
- * @section tunnel_state_client Client-mode state
- *
- * An OpenVPN process running in client-mode can manage at most one single
- * VPN tunnel at any one time. The state information for a client's VPN
- * tunnel is stored in a \c context structure.
- *
- * The \c context structure is created in the \c main() function. That is
- * also where process-wide initialization takes place, such as parsing
- * command line %options and reading configuration files. The \c context
- * is then passed to \c tunnel_point_to_point() which drives OpenVPN's
- * main event processing loop. These functions are both part of the \link
- * eventloop Main Event Loop\endlink module.
- *
- * @subsection tunnel_state_client_init Initialization and cleanup
- *
- * Because there is only one \c context structure present, it can be
- * initialized and cleaned up from the client's main event processing
- * function. Before the \c tunnel_point_to_point() function enters its
- * event loop, it calls \c init_instance_handle_signals() which calls \c
- * init_instance() to initialize the single \c context structure. After
- * the event loop stops, it calls \c close_instance() to clean up the \c
- * context.
- *
- * @subsection tunnel_state_client_event Event processing
- *
- * When the main event processing loop activates the external or internal
- * multiplexer to handle a network event, it is not necessary to determine
- * which VPN tunnel the event is associated with, because there is only
- * one VPN tunnel active.
- *
- * @section tunnel_state_server Server-mode state
- *
- * An OpenVPN process running in server-mode can manage multiple
- * simultaneously active VPN tunnels. For every VPN tunnel active, in
- * other words for every OpenVPN client which is connected to a server,
- * the OpenVPN server has one \c context structure in which it stores that
- * particular VPN tunnel's state information.
- *
- * @subsection tunnel_state_server_multi Multi_context and multi_instance structures
- *
- * To support multiple \c context structures, each is wrapped in a \c
- * multi_instance structure, and all the \c multi_instance structures are
- * registered in one single \c multi_context structure. The \link
- * external_multiplexer External Multiplexer\endlink and \link
- * internal_multiplexer Internal Multiplexer\endlink then use the \c
- * multi_context to retrieve the correct \c multi_instance and \c context
- * associated with a given network address.
- *
- * @subsection tunnel_state_server_init Startup and initialization
- *
- * An OpenVPN process running in server-mode starts in the same \c main()
- * function as it would in client-mode. The same process-wide
- * initialization is performed, and the resulting state and configuration
- * is stored in a \c context structure. The server-mode and client-mode
- * processes diverge when the \c main() function calls one of \c
- * tunnel_point_to_point() or \c tunnel_server().
- *
- * In server-mode, \c main() calls the \c tunnel_server() function, which
- * transfers control to \c tunnel_server_udp_single_threaded() or \c
- * tunnel_server_tcp() depending on the external transport protocol.
- *
- * These functions receive the \c context created in \c main(). This
- * object has a special status in server-mode, as it does not represent an
- * active VPN tunnel, but does contain process-wide configuration
- * parameters. In the source code, it is often stored in "top" variables.
- * To distinguish this object from other instances of the same type, its
- * \c context.mode value is set to \c CM_TOP. Other \c context objects,
- * which do represent active VPN tunnels, have a \c context.mode set to \c
- * CM_CHILD_UDP or \c CM_CHILD_TCP, depending on the external transport
- * protocol.
- *
- * Both \c tunnel_server_udp_single_threaded() and \c tunnel_server_tcp()
- * perform similar initialization. In either case, a \c multi_context
- * structure is created, and it is initialized according to the
- * configuration stored in the top \c context by the \c multi_init() and
- * \c multi_top_init() functions.
- *
- * @subsection tunnel_state_server_tunnels Creating and destroying VPN tunnels
- *
- * When an OpenVPN client makes a new connection to a server, the server
- * creates a new \c context and \c multi_instance. The latter is
- * registered in the \c multi_context, which makes it possible for the
- * external and internal multiplexers to retrieve the correct \c
- * multi_instance and \c context when a network event occurs.
- *
- * @subsection tunnel_state_server_cleanup Final cleanup
- *
- * After the main event loop exits, both \c
- * tunnel_server_udp_single_threaded() and \c tunnel_server_tcp() perform
- * similar cleanup. They call \c multi_uninit() followed by \c
- * multi_top_free() to clean up the \c multi_context structure.
