<p>To implement a new carrier for the Erlang distribution, the main
steps are as follows.</p>
+ <note><p>
+ As of ERTS version 10.0 support for distribution controller
+ processes has been introduced. That is, the traffic over a
+ distribution channel can be managed by a process instead of
+ only by a port. This makes it possible to implement large
+ parts of the logic in Erlang code, and you perhaps do not
+ even need a new driver for the protocol. One example could
+ be Erlang distribution over UDP using <c>gen_udp</c> (your
+ Erlang code will of course have to take care of retranspissions,
+ etc in this example). That is, depending on what you want
+ to do you perhaps do not need to implement a driver at all
+ and can then skip the driver related sections below.
+ The <c>gen_tcp_dist</c> example described in the

+ Module</seealso> section utilize distribution controller
+ processes and can be worth having a look at if you want to
+ use distribution controller processes.

+ <title>Distribution Module</title>
+ <p>
+ The distribution module expose an API that <c>net_kernel</c> call
+ in order to manage connections to other nodes. The module name
+ should have the suffix <c>_dist</c>.
+ </p>
+ <p>
+ The module needs to create some kind of listening entity (process
+ or port) and an acceptor process that accepts incoming connections
+ using the listening entity. For each connection, the module at least
+ needs to create one connection supervisor process, which also is
+ responsible for the handshake when setting up the connection, and
+ a distribution controller (process or port) responsible for
+ transport of data over the connection. The distribution controller
+ and the connection supervisor process should be linked together
+ so both of them are cleaned up when the connection is taken down.
+ </p>
+ <p>
+ Note that there need to be exactly one distribution controller
+ per connection. A process or port can only be distribution
+ controller for one connection. The registration as distribution
+ controller cannot be undone. It will stick until the distribution
+ controller terminates. The distribution controller should not
+ ignore exit signals. It is allowed to trap exits, but it should
+ then voluntarily terminate when an exit signal is received.
+ </p>
+ <p>
+ An example implementation of a distribution module can be found
+ in
+ <url href="gen_tcp_dist.erl">$ERL_TOP/lib/kernel/examples/gen_tcp_dist/src/gen_tcp_dist.erl</url>.
+ It implements the distribution over TCP/IP using the <c>gen_tcp</c>
+ API with distribution controllers implemented by processes. This
+ instead of using port distribution controllers as the ordinary TCP/IP
+ distribution uses.

+ <title>Exported Callback Functions</title>
+
+ <p>
+ The following functions are mandatory:
+ </p>
+ <taglist>
+ <tag><marker id="listen"/><c>listen(Name) -></c><br/>&nbsp;&nbsp;<c>{ok, {Listen, Address, Creation}} | {error, Error} </c></tag>
+ <item>
+ <p>
+ <c>listen/1</c> is called once in order to listen for incoming
+ connection requests. The call is made when the distribution is brought
+ up. The argument <c>Name</c> is the part of the node name before
+ the <c>@</c> sign in the full node name. It can be either an atom or a
+ string.
+ </p>
+ <p>
+ The return value consists of a <c>Listen</c> handle (which is
+ later passed to the <seealso marker="#accept"><c>accept/1</c></seealso>
+ callback), <c>Address</c> which is a <c>#net_address{}</c> record
+ with information about the address for the node (the
+ <c>#net_address{}</c> record is defined in
+ <c>kernel/include/net_address.hrl</c>), and <c>Creation</c> which
+ (currently) is an integer <c>1</c>, <c>2</c>, or <c>3</c>.
+ </p>
+ <p>
+ If <seealso marker="erts:epmd"><c>epmd</c></seealso> is to be used
+ for node discovery, you typically want to use the (unfortunately
+ undocumented) <c>erl_epmd</c> module (part of the <c>kernel</c>
+ application) in order to register the listen port with <c>epmd</c>
+ and retrieve <c>Creation</c> to use.

+ <p>
+ <c>accept/1</c> should spawn a process that accepts connections. This
+ process should preferably execute on <c>max</c> priority. The process
+ identifier of this process should be returned.
+ </p>
+ <p>
+ The <c>Listen</c> argument will be the same as the <c>Listen</c> handle
+ part of the return value of the
+ <seealso marker="#listen"><c>listen/1</c></seealso> callback above.
+ <c>accept/1</c> is called only once when the distribution protocol is
+ started.
+ </p>

+ The caller of this function is a representative for <c>net_kernel</c>
+ (this may or may not be the process registered as <c>net_kernel</c>)
+ and is in this document identified as <c>Kernel</c>.
+ When a connection has been accepted by the acceptor process, it needs
+ to inform <c>Kernel</c> about the accepted connection. This is done by
+ passing a message on the form:
+ </p>
+ <code type="none"><![CDATA[Kernel ! {accept, AcceptorPid, DistController, Family, Proto}]]></code>
+ <p>
+ <c>DistController</c> is either the process or port identifier
+ of the distribution controller for the connection. The
+ distribution controller should be created by the acceptor
+ processes when a new connection is accepted. Its job is to
+ dispatch traffic on the connection.
+ </p>
+ <c>Kernel</c> responds with one of the following messages:
+ <taglist>

+ * @author Rickard Green

+ *
+ * There are two major different implementations off IO polling in this
+ * file. The concurrent and non-concurrent implementations.
+ * When available epoll/kqueue are used to implement the concurrent
+ * versions. poll, select and dev/poll use non-concurrent updates.
+ *
+ * Concurrent version:
+ * In the concurrent version erts_poll_control directly modifies
+ * the kernel pollset without waking the thread that is waiting
+ * on events. Also the ErtsPollResFd type is directly mapped to
+ * the native event type, so no extra copying is needed. Note that
+ * as no locking at all is done, fds can be triggered that have been
+ * removed from the pollset. The check_io layer has to deal with this.
+ *
+ * Non-concurrent version:
+ * In the non-concurrent version, the pollset has an internal representation
+ * of the pollset that is updated by erts_poll_control. When an fd is updated,
+ * its number is placed in the update request queue and then the waiting thread
+ * is woken in order to see the change. The internal data in the pollset is
+ * protected by a mutex that has to be taken by both the modifying and waiting
+ * thread at different times.
*
+ * The non-concurrent pollset cannot have fd's closed in it while a thread is
+ * waiting on that fd. In order to fix this, when an ERTS_POLL_OP_DEL command
+ * is issued, the fd is marked as closing and the waiting thread is woken. The
+ * fd is then returned in the waiting threads results as ERTS_POLL_EV_NONE.

+ * @author: Rickard Green

*
- * Author: Rickard Green
+ * defines:
+ * ERTS_POLL_EV_NONE - No events have been set. This is not the same as 0.
+ * ERTS_POLL_EV_IN - Represent an IN event
+ * ERTS_POLL_EV_OUT - Represent an OUT event
+ * ERTS_POLL_EV_ERR - Represent an error event
+ * ERTS_POLL_EV_NVAL - Represent an invalid event
+ *
+ * macro functions:
+ * ErtsSysFdType ERTS_POLL_RES_GET_FD(ErtsPollResFd *evt);
+ * void ERTS_POLL_RES_SET_FD(ErtsPollResFd *evt, ErtsSysFdType fd);
+ * ErtsPollEvents ERTS_POLL_RES_GET_EVTS(ErtsPollResFd *evt)

- %% This is an ugly hack. Upgrading a socket to TLS requires the
- %% crypto module to be loaded. Loading the crypto module triggers
- %% its on_load function, which calls code:priv_dir/1 to find the
- %% directory where its NIF library is. However, distribution is
- %% started earlier than the code server, so the code server is not
- %% necessarily started yet, and code:priv_dir/1 might fail because
- %% of that, if we receive an incoming connection on the
- %% distribution port early enough.
- %%
- %% If the on_load function of a module fails, the module is
- %% unloaded, and the function call that triggered loading it fails
- %% with 'undef', which is rather confusing.
- %%
- %% Thus, the ssl_tls_dist_proxy process will terminate, and be
- %% restarted by ssl_dist_sup. However, it won't have any memory
- %% of being asked by net_kernel to listen for incoming
- %% connections. Hence, the node will believe that it's open for
- %% distribution, but it actually isn't.
