+Dante is a circuit-level firewall/proxy that can be used to provide convenient
+and secure network connectivity, requiring only that the server Dante runs on
+has external network connectivity. Dante is used daily by Fortune 100 companies
+and large international organizations, either as a standard SOCKS server or as
+a "reverse proxy".

+ Netfilter (IPv4/IPv6) module for matching cluster
+ This option allows you to build work-load-sharing clusters of
+ network servers/stateful firewalls without having a dedicated
+ load-balancing router/server/switch. Basically, this match returns
+ true when the packet must be handled by this cluster node. Thus,
+ all nodes see all packets and this match decides which node handles
+ what packets. The work-load sharing algorithm is based on source
+ address hashing.
+
+ This module is usable for ipv4 and ipv6.
+
+ If you select it, it enables kmod-ipt-cluster.
+
+ see `iptables -m cluster --help` for more information.

+define Package/iwcap/description
+  The iwcap utility receives radiotap packet data from wifi monitor interfaces
+  and outputs it to pcap format. It gathers recived packets in a fixed ring
+  buffer to dump them on demand which is useful for background monitoring.
+  Alternatively the utility can stream the data to stdout to act as remote
+  capture drone for Wireshark or similar programs.

++ * 2013-03-04: Il'inykh Sergey <sergeyi at inango-sw.com>. Inango Systems Ltd
++ *	- fixed rtcp nat mapping and other port mapping fixes
++ *	- simple TEARDOWN request handling

++ *
++ * name:
++ *   This member is used throughout the system. It is also exported
++ *   to Lua as a variable name holding the index of the 'supported_protocols'
++ *   array. The name is also used as the name of the generated Lua
++ *   metatable, that is why inside the macro checkpacketseg_ it
++ *   is always the name of a protocol buffer that is passed as the
++ *   second parameter.
++ * payload_field:
++ *   This member holds the string of the field responsible for payload
++ *   data. The payload field of a protocol has an extra property, since
++ *   it can be used to invoke another protocol buffer that is applied to
++ *   the payload content.
++ * has_protocol:
++ *   This member is used together with the payload_field. Since we must
++ *   be sure that the payload content does really contain a protocol
++ *   of type X. The function pointed to by has_protocol checks if the
++ *   protocol buffer X can be applied on the payload_data.
++ * protocol_fields:
++ *   This member points to the array of 'protocol_field' structures
++ * get_field_changes:
++ *   This member is optional. It is used to return a pointer to an initialized
++ *   field_changes struct. The function is called, whenever the payload field
++ *   is requested with a given protocol type. Usually this function will
++ *   initialize the field_changes struct depending on the content of the 
++ *   payload data. e.g.
++ *     tcp = ip:data(packet_tcp)
++ *   such a request will call the 'get_field_changes' function of the tcp
++ *   protocol buffer. This enables, that the tcp options field have the proper
++ *   length as well as the tcp data start at the right offset.

++
++  (*) In OP_VARARG, if (B == 0) then use actual number of varargs and
++      set top (like in OP_CALL with C == 0).
++
++  (*) In OP_RETURN, if (B == 0) then return up to `top'
++
++  (*) In OP_SETLIST, if (B == 0) then B = `top';
++      if (C == 0) then next `instruction' is real C
++
++  (*) For comparisons, A specifies what condition the test should accept

++** Implementation of tables (aka arrays, objects, or hash tables).
++** Tables keep its elements in two parts: an array part and a hash part.
++** Non-negative integer keys are all candidates to be kept in the array
++** part. The actual size of the array is the largest `n' such that at
++** least half the slots between 0 and n are in use.
++** Hash uses a mix of chained scatter table with Brent's variation.
++** A main invariant of these tables is that, if an element is not
++** in its main position (i.e. the `original' position that its hash gives
++** to it), then the colliding element is in its own main position.
++** Hence even when the load factor reaches 100%, performance remains good.

++ * lua_tg_checkentry
++ * -----------------
++ * This function is used as a kernel-side sanity check of the data comming
++ * from the iptables userspace program. Since this is the function which is
++ * called everytime a new rule (with -j xt_LUA) is injected, this function
++ * is used to do the bookkeeping work, such as counting the reference of
++ * several Lua states and the initialization of new states if needed. As an
++ * extra initialization step it loads the provided Lua script into the Lua
++ * state.
++ *
++ * Lua state initialization
++ * ~~~~~~~~~~~~~~~~~~~~~~~~
++ * 1. If a new rule is inserted and there is no existing state for the given
++ *    state identifier (default state identifier is 0) a new Lua state is
++ *    initialized using *lua_open*.
++ * 2. The Lua base library is registered inside the newly initialized state.
++ *    Have a look at *lua/lbaselib.c* to see what functions of the Lua base
++ *    library are available inside Lua.
++ * 3. The Lua packet library is registered inside the Lua state using the
++ *    function *register_lua_packet_lib*. So far this function only registers
++ *    the Netfilter verdicts NF_ACCEPT, NF_DROP and XT_CONTINUE inside the
++ *    global environment of the given Lua state.
++ * 4. All the protocol Buffers, and the functions for accessing the bytes are
++ *    registered using *register_protocols*.
++ *
++ * Lua state reference counting
++ * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
++ * Bookkeeping of the Lua states inside the *lua_state_refs* array. The
++ * state identifier is mapped to the array index, which holds an integer
++ * counting the several initialized states.
++ *
++ * Loading the Lua script
++ * ~~~~~~~~~~~~~~~~~~~~~~
++ * Copying the buffer which was initialized by the userspace program to a
++ * buffer with the proper size. The script is then loaded by the function
++ * xt_LUA_loadcode, which wrapps the *luaL_loadbuffer* function and does
++ * some workqueue initialization. So far this is done each time this function
++ * is called, subject to change.
