* Section: Plugin Functions v5
*
* This is the plugin version 5 interface, which covers authentication, access
* control, the $CONTROL topic space handling, and message inspection and
* modification.
*
* This interface is available from v2.0 onwards.
*
* There are just three functions to implement in your plugin. You should
* register callbacks to handle different events in your
* mosquitto_plugin_init() function. See mosquitto_broker.h for the events and
* callback registering functions.
*
* ========================================================================= */
/*
* Function: mosquitto_plugin_version
*
* The broker will attempt to call this function immediately after loading the
* plugin to check it is a supported plugin version. Your code must simply
* return the plugin interface version you support, i.e. 5.
*
* The supported_versions array tells you which plugin versions the broker supports.
*
* If the broker does not support the version that you require, return -1 to
* indicate failure.
*
* HELPER: If you only wish to declare support for a single version, you can
* use the helper macro:
*
* MOSQUITTO_PLUGIN_DECLARE_VERSION(5);

*
* This is the plugin version 4 interface, which is exclusively for

*
* You must implement these functions in your plugin.
*
* Authentication plugins can implement one or both of authentication and
* access control. If your plugin does not wish to handle either of
* authentication or access control it should return MOSQ_ERR_PLUGIN_DEFER. In
* this case, the next plugin will handle it. If all plugins return
* MOSQ_ERR_PLUGIN_DEFER, the request will be denied.
*
* For each check, the following flow happens:
*
* * The default password file and/or acl file checks are made. If either one
* of these is not defined, then they are considered to be deferred. If either
* one accepts the check, no further checks are made. If an error occurs, the
* check is denied
* * The first plugin does the check, if it returns anything other than
* MOSQ_ERR_PLUGIN_DEFER, then the check returns immediately. If the plugin
* returns MOSQ_ERR_PLUGIN_DEFER then the next plugin runs its check.
* * If the final plugin returns MOSQ_ERR_PLUGIN_DEFER, then access will be

* Function: mosquitto_disconnect_v5
*
* Disconnect from the broker, with attached MQTT properties.
*
* Use e.g. <mosquitto_property_add_string> and similar to create a list of
* properties, then attach them to this publish. Properties need freeing with
* <mosquitto_property_free_all>.
*
* If the mosquitto instance `mosq` is using MQTT v5, the `properties` argument
* will be applied to the DISCONNECT message. For MQTT v3.1.1 and below, the
* `properties` argument will be ignored.
*
* Set your client to use MQTT v5 immediately after it is created:
*
* mosquitto_int_option(mosq, MOSQ_OPT_PROTOCOL_VERSION, MQTT_PROTOCOL_V5);
*
* Parameters:
* mosq - a valid mosquitto instance.
* reason_code - the disconnect reason code.
* properties - a valid mosquitto_property list, or NULL.
*
* Returns:
* MOSQ_ERR_SUCCESS - on success.
* MOSQ_ERR_INVAL - if the input parameters were invalid.
* MOSQ_ERR_NO_CONN - if the client isn't connected to a broker.
* MOSQ_ERR_DUPLICATE_PROPERTY - if a property is duplicated where it is forbidden.
* MOSQ_ERR_PROTOCOL - if any property is invalid for use with DISCONNECT.

/*
* Function: mosquitto_int_option
*
* Used to set integer options for the client.
*
* Parameters:
* mosq - a valid mosquitto instance.
* option - the option to set.
* value - the option specific value.
*
* Options:
* MOSQ_OPT_TCP_NODELAY - Set to 1 to disable Nagle's algorithm on client
* sockets. This has the effect of reducing latency of individual
* messages at the potential cost of increasing the number of
* packets being sent.
* Defaults to 0, which means Nagle remains enabled.
*
* MOSQ_OPT_PROTOCOL_VERSION - Value must be set to either MQTT_PROTOCOL_V31,
* MQTT_PROTOCOL_V311, or MQTT_PROTOCOL_V5. Must be set before the
* client connects. Defaults to MQTT_PROTOCOL_V311.
*
* MOSQ_OPT_RECEIVE_MAXIMUM - Value can be set between 1 and 65535 inclusive,
* and represents the maximum number of incoming QoS 1 and QoS 2
* messages that this client wants to process at once. Defaults to
* 20. This option is not valid for MQTT v3.1 or v3.1.1 clients.
* Note that if the MQTT_PROP_RECEIVE_MAXIMUM property is in the
* proplist passed to mosquitto_connect_v5(), then that property
* will override this option. Using this option is the recommended
* method however.
*
* MOSQ_OPT_SEND_MAXIMUM - Value can be set between 1 and 65535 inclusive,
* and represents the maximum number of outgoing QoS 1 and QoS 2
* messages that this client will attempt to have "in flight" at
* once. Defaults to 20.
* This option is not valid for MQTT v3.1 or v3.1.1 clients.
* Note that if the broker being connected to sends a
* MQTT_PROP_RECEIVE_MAXIMUM property that has a lower value than
* this option, then the broker provided value will be used.
*
* MOSQ_OPT_SSL_CTX_WITH_DEFAULTS - If value is set to a non zero value,
* then the user specified SSL_CTX passed in using MOSQ_OPT_SSL_CTX
* will have the default options applied to it. This means that
* you only need to change the values that are relevant to you.
* If you use this option then you must configure the TLS options
* as normal, i.e. you should use <mosquitto_tls_set> to
* configure the cafile/capath as a minimum.
* This option is only available for openssl 1.1.0 and higher.
*
* MOSQ_OPT_TLS_OCSP_REQUIRED - Set whether OCSP checking on TLS
* connections is required. Set to 1 to enable checking,
* or 0 (the default) for no checking.
*
* MOSQ_OPT_TLS_USE_OS_CERTS - Set to 1 to instruct the client to load and
* trust OS provided CA certificates for use with TLS connections.
* Set to 0 (the default) to only use manually specified CA certs.
*
* MOSQ_OPT_DISABLE_SOCKETPAIR - By default, each client connected will create
* an internal pair of connected sockets to allow the network thread
* to be notified and woken up if another thread calls
* <mosquitto_publish> or other similar command. If you are
* operating with an external loop, this is not necessary and
* consumes an extra two sockets per client. Set this option to 1 to
* disable the use of the socket pair.
*
* MOSQ_OPT_TRANSPORT - Have the client connect with either MQTT over TCP as
* normal, or MQTT over WebSockets. Set the value to MOSQ_T_TCP or
* MOSQ_T_WEBSOCKETS.
*
* MOSQ_OPT_HTTP_HEADER_SIZE - Size the size of buffer that will be allocated
* to store the incoming HTTP header when using Websocket transport.
* Defaults to 4096. Setting to below 100 will result in a return
* value of MOSQ_ERR_INVAL. This should be set before starting the
* connection. If you try to set this when the initial http request
* is underway then it will return MOSQ_ERR_INVAL.

* Must be a valid engine, and note that the string will not be used
* until a connection attempt is made so this function will return

*
* MOSQ_OPT_TLS_KEYFORM - Configure the client to treat the keyfile
* differently depending on its type. Must be set
* before <mosquitto_connect>.
* Set as either "pem" or "engine", to determine from where the
* private key for a TLS connection will be obtained. Defaults to

*
* MOSQ_OPT_TLS_KPASS_SHA1 - Where the TLS Engine requires the use of
* a password to be accessed, this option allows a hex encoded
* SHA1 hash of the private key password to be passed to the
* engine directly. Must be set before <mosquitto_connect>.
*
* MOSQ_OPT_TLS_ALPN - If the broker being connected to has multiple
* services available on a single TLS port, such as both MQTT

* option for the connection.

* Function: mosquitto_tls_insecure_set

* This interface is available from v2.0 onwards.
*
* There are just three functions to implement in your plugin. You should

*
* The supported_versions array tells you which plugin versions the broker supports.

* If the broker does not support the version that you require, return -1 to

*
* You must implement these functions in your plugin.

* Authentication plugins can implement one or both of authentication and

*
* For each check, the following flow happens:

* of these is not defined, then they are considered to be deferred. If either
* one accepts the check, no further checks are made. If an error occurs, the
* check is denied
* * The first plugin does the check, if it returns anything other than
