net: lwm2m: initial library support for LWM2M Origin: SICS-IoT / Contiki OS URL: https://github.com/sics-iot/lwm2m-contiki/tree/lwm2m-standalone-dtls commit: d07b0bcd77ec7e8b93787669507f3d86cfbea64a Purpose: Introduction of LwM2M client library. Maintained-by: Zephyr Lightweight Machine-to-Machine (LwM2M) is a protocol stack extension of the Constrained Application Protocol (CoAP) which uses UDP transmission packets. This library was based on source worked on by Joakim Eriksson, Niclas Finne and Joel Hoglund which was adopted by Contiki and then later revamped to work as a stand-alone library. A VERY high level summary of the changes made: - [ALL] sources were re-formatted to Zephyr coding standards - [engine] The engine portion was re-written due to the heavy reliance on ER-CoAP APIs which are not compatible to the Zephyr CoAP APIs as well as other Zephyr specific needs. - [engine] All LWM2M/IPSO object data is now abstracted into resource data which stores information like the data type, length, callbacks to help with read/write. The engine modifies this data directly (or makes callbacks) instead of all of the logic for this living in each object's code. (This wasn't scaling well as I was implementing changes). - [engine] Related to the above change, I also added a generic set of getter/setter functions that user applications can call to change the object data instead of having to add getter/setting methods in each object. - [engine] The original sources shared the engine's context structure quite extensively causing a problem with portability. I broke up the context into it's individual parts: LWM2M path data, input data and output data and pass only the needed data into each set of APIs. - [content format read/writer] sources were re-organized into single .c/h files per content formatter. - [content format read/writer] sources were re-written where necessary to remove the sharing of the lwm2m engine's context and instead only requires the path and input or output data specific to it's function. - [LwM2M objects] re-written using the new engine's abstractions Signed-off-by: Michael Scott <michael.scott@linaro.org>

net: lwm2m: move to flat buffers As part of the migration from net_app APIs to socket APIs, let's stop referencing the net_pkt fragments throughout the LwM2M library. Establish a msg_data flat buffer inside lwm2m_message and use that instead. NOTE: As a part of this change we remove the COAP_NET_PKT setting. The COAP library reverts to COAP_SOCK behavior. This doesn't mean we use sockets in LwM2M (yet), it only means we use the socket-compatible COAP library which parses flat buffers instead of net_pkt fragments.

default 1536 if NET_LOG
Kconfig: Use the first default with a satisfied condition Up until now, Zephyr has patched Kconfig to use the last 'default' with a satisfied condition, instead of the first one. I'm not sure why the patch was added (it predates Kconfiglib), but I suspect it's related to Kconfig.defconfig files. There are at least three problems with the patch: 1. It's inconsistent with how Kconfig works in other projects, which might confuse newcomers. 2. Due to oversights, earlier 'range' properties are still preferred, as well as earlier 'default' properties on choices. In addition to being inconsistent, this makes it impossible to override 'range' properties and choice 'default' properties if the base definition of the symbol/choice already has 'range'/'default' properties. I've seen errors caused by the inconsistency, and I suspect there are more. 3. A fork of Kconfiglib that adds the patch needs to be maintained. Get rid of the patch and go back to standard Kconfig behavior, as follows: 1. Include the Kconfig.defconfig files first instead of last in Kconfig.zephyr. 2. Include boards/Kconfig and arch/<arch>/Kconfig first instead of last in arch/Kconfig. 3. Include arch/<arch>/soc/*/Kconfig first instead of last in arch/<arch>/Kconfig. 4. Swap a few other 'source's to preserve behavior for some scattered symbols with multiple definitions. Swap 'source's in some no-op cases too, where it might match the intent. 5. Reverse the defaults on symbol definitions that have more than one default. Skip defaults that are mutually exclusive, e.g. where each default has an 'if <some board>' condition. They are already safe. 6. Remove the prefer-later-defaults patch from Kconfiglib. Testing was done with a Python script that lists all Kconfig symbols/choices with multiple defaults, along with a whitelist of fixed symbols. The script also verifies that there are no "unreachable" defaults hidden by defaults without conditions As an additional test, zephyr/.config was generated before and after the change for several samples and checked to be identical (after sorting). This commit includes some default-related cleanups as well: - Simplify some symbol definitions, e.g. where a default has 'if FOO' when the symbol already has 'depends on FOO'. - Remove some redundant 'default ""' for string symbols. This is the implicit default. Piggyback fixes for swapped ranges on BT_L2CAP_RX_MTU and BT_L2CAP_TX_MTU (caused by confusing inconsistency). Piggyback some fixes for style nits too, e.g. unindented help texts. Signed-off-by: Ulf Magnusson <Ulf.Magnusson@nordicsemi.no>

net: lwm2m: refactor engine to use lwm2m_message structure Sending an lwm2m message is too difficult. It requires pending / reply and other structures to be configured and set by various portions of the library. There is also no way to know if a pending message ever encounters a timeout. Let's fix this by simplifying the internal LwM2M engine APIs for handling lwm2m messages: 1. A user calls lwm2m_get_message(lwm2m_ctx) which returns the first available lwm2m message from an array of messages (total # of messages is set via CONFIG_LWM2M_ENGINE_MAX_MESSAGES). 2. Next the user sets all of the fields in the message that are required (type, code message id, token, etc) 3. Then the user calls lwm2m_init_message(msg). This initializes the underlying zoap_packet, pending and reply structures. 4. Once initialized, the user creates their payload in msg->zpkt. 5. When the user is ready to send, the call lwm2m_send_message(msg). 6. And if for some reason an error occurs at any point, they can free up the entire set of structures with: lwm2m_release_message(msg). Included in the refactoring is a timeout_cb field which can be set in the LwM2M messages. If a pending structure ever expires the engine will call the timeout_cb passing in the msg structure before it's automatically released. Signed-off-by: Michael Scott <michael.scott@linaro.org>

This library was based on source worked on by Joakim Eriksson, Niclas Finne and Joel Hoglund which was adopted by Contiki and then later revamped to work as a stand-alone library. A VERY high level summary of the changes made: - [ALL] sources were re-formatted to Zephyr coding standards - [engine] The engine portion was re-written due to the heavy reliance on ER-CoAP APIs which are not compatible to the Zephyr CoAP APIs as well as other Zephyr specific needs. - [engine] All LWM2M/IPSO object data is now abstracted into resource data which stores information like the data type, length, callbacks to help with read/write. The engine modifies this data directly (or makes callbacks) instead of all of the logic for this living in each object's code. (This wasn't scaling well as I was implementing changes). - [engine] Related to the above change, I also added a generic set of getter/setter functions that user applications can call to change the object data instead of having to add getter/setting methods in each object. - [engine] The original sources shared the engine's context structure quite extensively causing a problem with portability. I broke up the context into it's individual parts: LWM2M path data, input data and output data and pass only the needed data into each set of APIs. - [content format read/writer] sources were re-organized into single .c/h files per content formatter. - [content format read/writer] sources were re-written where necessary to remove the sharing of the lwm2m engine's context and instead only requires the path and input or output data specific to it's function. - [LwM2M objects] re-written using the new engine's abstractions Signed-off-by: Michael Scott <michael.scott@linaro.org>

net: lwm2m: default LWM2M_LOCAL_PORT to 0 (random) Due to a bug where LWM2M_LOCAL_PORT was not being honored, all outgoing traffic from the LwM2M client was coming from a random port determined during initialization. Now that this bug bas been fixed, let's default the client to the behavior that most users are expecting, and let new users customize the outgoing port if needed (which should be rarely).

This is the client port for LWM2M communication. The default
setting of 0 sets a random port for the client to be used for
outgoing communication.
