Changes applied by this patch: - Add the mqtt_publisher_parser routine - Add the MQTT_PACKET_TYPE macro to get the MQTT msg packet type (required by mqtt_publisher_parser) - Add the mqtt_linearize_buffer (required by mqtt_publisher_parser) - Add the mqtt_recv callback for reception - Modify the mqtt_init routine to install the reception callback The mqtt_publisher_parser routine is a callback used internally to execute the appropriate mqtt_rx routine. Only the following messages are handled by this routine: MQTT_CONNACK, MQTT_PUBACK, MQTT_PUBREC, MQTT_PUBCOMP and MQTT_PINGRESP. On error, it executes the ctx->malformed cb, if defined. This commit also introduces the mqtt_linearize_buffer routine that will be used to linearize an IP stack fragmented buffer. This patch makes use of the net_nbuf_linear_copy routine to linearize the incoming buffer. mqtt_rx_xxxx routines are also updated to handle linear buffers (no fragmentation). Currently, all the network protocol routines assume that the input buffer is not fragmented. Future versions will remove that assumption and the mqtt_linearize_buffer routine will be removed as well. Public MQTT API is not affected by this patch. Change-Id: I02fece67052ffbc7cb393d5ca545c503da463c4b Signed-off-by: Flavio Santes <flavio.santes@intel.com> |
