+# The Versatile IKE Control Interface (VICI) protocol #
+
+The vici plugin implements the server side of an IPC protocol to configure,
+monitor and control the IKE daemon charon. It uses request/response and event
+messages to communicate over a reliable stream based transport.
+
+## Transport protocol ##
+
+To provide the service, the plugin opens a listening socket using a reliable,
+stream based transport. charon relies on the different stream service
+abstractions provided by libstrongswan, such as TCP and UNIX sockets.
+
+A client connects to this service to access functionality. It may send an
+arbitrary number of packets over the connection before closing it.
+
+To exchange data, the transport protocol is segmented into byte sequences.
+Each byte sequence is prefixed by a 32-bit length header in network order,
+followed by the data. The maximum segment length is currently limited to 512KB
+of data, and the length field contains the length of the data only, not
+including the length field itself.
+
+The order of byte sequences must be strict, byte sequences must arrive in the
+same order as sent.
+
+## Packet layer ##
+
+Within the byte sequences defined by the transport layer, both the client
+and the server can exchange packets. The type of packet defines its structure
+and purpose. The packet type is a 8-bit identifier, and is the first byte
+in a transport layer byte sequence. The length of the packet is given by the
+transport layer.
+
+While a packet type may define the format of the wrapped data freely, currently
+all types either contain a name, a message or both. The following packet types
+are currently defined:
+
+* _CMD_REQUEST = 0_: A named request message
+* _CMD_RESPONSE = 1_: An unnamed response message for a request
+* _CMD_UNKNOWN = 2_: An unnamed response if requested command is unknown
+* _EVENT_REGISTER = 3_: A named event registration request
+* _EVENT_UNREGISTER = 4_: A named event deregistration request
+* _EVENT_CONFIRM = 5_: An unnamed response for successful event (de-)registration
+* _EVENT_UNKNOWN = 6_: A unnamed response if event (de-)registration failed
+* _EVENT = 7_: A named event message
+
+For packets having a named type, after the packet type an 8-bit length header
+of the name follows, indicating the string length in bytes of the name tag, not
+including the length field itself. The name is an ASCII string that is not
+null-terminated.
+
+The rest of the packet forms the exchanged message, the length is determined
+by the transport byte sequence length, subtracting the packet type and
+the optional name tag in some messages.
+
+### Commands ###
+
+Commands are currently always requested by the client. The server replies with
+a response, or with a CMD_UNKNOWN failure message to let the client know
+that it does not have a handler for such a command. There is no sequence number
+to associate responses to requests, so only one command can be active at
+a time on a single connection.
+
+### Events ###
+
+To receive event messages, the client explicitly registers for events by name,
+and also unregisters if it does not want to receive events of the named kind
+anymore. The server confirms event registration using EVENT_CONFIRM, or
+indicates that there is no such event source with EVENT_UNKNOWN.
+
+Events may get raised at any time while registered, even during an active
+request command. This mechanism is used to feed continuous data during a request,
+for example.
+
+## Message format ##
+
+The defined packet types optionally wrap a message with additional data.
+Messages are currently used in CMD_REQUEST/CMD_RESPONSE, and in EVENT packets.
+A message uses a hierarchial tree of sections. Each section (or the implicit
+root section) contains an arbitrary set of key/value pairs, lists and
+sub-sections. The length of a message is not part of the message itself, but
+the wrapping layer, usually calculated from the transport byte sequence length.
+
+The message encoding consists of a sequence of elements. Each element starts
+with the element type, optionally followed by an element name and/or an element
+value. Currently the following message element types are defined:
+
+* _SECTION_START = 0_: Begin a new section having a name
+* _SECTION_END = 1_: End a previously started section
+* _KEY_VALUE = 2_: Define a value for a named key in the current section
+* _LIST_START = 3_: Begin a named list for list items
+* _LIST_ITEM = 4_: Define an unnamed item value in the current list
+* _LIST_END = 5_: End a previously started list
+
+Types are encoded as 8-bit values. Types having a name (SECTION_START,
+KEY_VALUE and LIST_START) have an ASCII string following the type, which itself
+uses an 8-bit length header. The string must not be null-terminated, the string
+length does not include the length field itself.
+
+Types having a value (KEY_VALUE and LIST_ITEM) have a raw blob sequence,
+prefixed with a 16-bit network order length. The blob follows the type or the
+name tag if available, the length defined by the length field does not include
+the length field itself.
+
+The interpretation of any value is not defined by the message format; it can
+take arbitrary blobs. The application may specify types for specific keys, such
+as strings or integer representations.
+
+### Sections ###
+
+Sections may be opened in the implicit root section, or any previously section.
+They can be nested to arbitrary levels. A SECTION_END marker always closes
+the last opened section; SECTION_START and SECTION_END items must be balanced
+in a valid message.
+
+### Key/Values ###
+
+Key/Value pair elements may appear in the implicit root section or any explicit
+sub-section at any level. Key names must be unique in the current section, use
+lists to define multiple values for a key. Key/values may not appear in lists,
+use a sub-section instead.
+
+### Lists ###
+
+Lists may appear at the same locations as Key/Values, and may not be nested.
+Only a single list may be opened at the same time, and all lists must be closed
+in valid messages. After opening a list, only list items may appear before the
+list closing element. Empty lists are allowed, list items may appear within
+lists only.
+
+### Encoding example ###
+
+Consider the following structure using pseudo-markup for this example:
+
+ key1 = value1
+ section1 = {
+ sub-section = {
+ key2 = value2
+ }
+ list1 = [ item1, item2 ]
+ }
+
+The example above reprensents a valid tree structure, that gets encoded as
+the following C array:
+
+ char msg[] = {
+ /* key1 = value1 */
+ 2, 4,'k','e','y','1', 0,6,'v','a','l','u','e','1',
+ /* section1 */
+ 0, 8,'s','e','c','t','i','o','n','1',
+ /* sub-section */
+ 0, 11,'s','u','b','-','s','e','c','t','i','o','n',
+ /* key2 = value2 */
+ 2, 4,'k','e','y','2', 0,6,'v','a','l','u','e','2',
+ /* sub-section end */
+ 1,
+ /* list1 */
+ 3, 5, 'l','i','s','t','1',
+ /* item1 */
+ 4, 0,5,'i','t','e','m','1',
+ /* item2 */
+ 4, 0,5,'i','t','e','m','2',
+ /* list1 end */
+ 5,
+ /* section1 end */
+ 1,
+ };
+
+# libvici C client library #
+
+libvici is the reference implementation of a C client library implementing
+the vici protocol. It builds upon libstrongswan, but provides a stable API
+to implement client applications in the C programming language. libvici uses
+the libstrongswan thread pool to deliver event messages asynchronously.
+
+More information about the libvici API is available in the libvici.h header
+file.

+/**
+ * @defgroup libvici libvici
+ * @{ @ingroup vici
+ *
+ * libvici is a low-level client library for the "Versatile IKE Control
+ * Interface" protocol. While it uses libstrongswan and its thread-pool for
+ * asynchronous message delivery, this interface does not directly depend on
+ * libstrongswan interfaces and should be stable.
+ *
+ * This interface provides the following basic functions:
+ *
+ * - vici_init()/vici_deinit(): Library initialization functions
+ * - vici_connect(): Connect to a vici service
+ * - vici_disconnect(): Disconnect from a vici service
+ *
+ * Library initialization implicitly initializes libstrongswan and a small
+ * thread pool.
+ *
+ * Connecting requires an uri, which is currently either a UNIX socket path
+ * prefixed with unix://, or a hostname:port touple prefixed with tcp://.
+ * Passing NULL takes the system default socket path.
+ *
+ * After the connection has been established, request messages can be sent.
+ * Only a single thread may operate on a single connection instance
+ * simultaneously. To construct request messages, use the following functions:
+ *
+ * - vici_add_key_value() / vici_add_key_valuef(): Add key/value pairs
+ * - vici_begin(): Start constructing a new request message
+ * - vici_begin_section(): Open a new section to add contents to
+ * - vici_end_section(): Close a previously opened session
+ * - vici_begin_list(): Open a new list to add list items to
+ * - vici_end_list(): Close a previously opened list
+ * - vici_add_list_item() / vici_add_list_itemf(): Add list item
+ *
+ * Once the request message is complete, it can be sent or cancelled with:
+ *
+ * - vici_submit()
+ * - vici_free_req()
+ *
+ * If submitting a message is successful, a response message is returned. It
+ * can be processed using the following functions:
+ *
+ * - vici_parse(): Parse content type
+ * - vici_parse_name(): Parse name if content type provides one
+ * - vici_parse_name_eq(): Parse name and check if matches string
+ * - vici_parse_value() / vici_parse_value_str(): Parse value for content type
+ * - vici_dump(): Dump a full response to a FILE stream
+ * - vici_free_res(): Free response after use
+ *
+ * Usually vici_parse() is called in a loop, and depending on the returned
+ * type the name and value can be inspected.
+ *
+ * To register or unregister for asynchronous event messages vici_register() is
+ * used. The registered callback gets invoked by an asynchronous thread. To
+ * parse the event message, the vici_parse*() functions can be used.
