RIOT-2021.10 - Release Notes
|
||||||
|
============================
|
||||||
|
RIOT is a multi-threading operating system which enables soft real-time
|
||||||
|
capabilities and comes with support for a range of devices that are typically
|
||||||
|
found in the Internet of Things: 8-bit and 16-bit microcontrollers as well as
|
||||||
|
light-weight 32-bit processors.
|
||||||
|
|
||||||
|
RIOT is based on the following design principles: energy-efficiency, soft
|
||||||
|
real-time capabilities, small memory footprint, modularity, and uniform API
|
||||||
|
access, independent of the underlying hardware (with partial POSIX compliance).
|
||||||
|
|
||||||
|
RIOT is developed by an international open-source community which is
|
||||||
|
independent of specific vendors (e.g. similarly to the Linux community) and is
|
||||||
|
licensed with a non-viral copyleft license (LGPLv2.1), which allows indirect
|
||||||
|
business models around the free open-source software platform provided by RIOT.
|
||||||
|
|
||||||
|
|
||||||
|
About this release
|
||||||
|
==================
|
||||||
|
|
||||||
|
The 2021.10 release includes:
|
||||||
|
|
||||||
|
The last three months again brought many new features, fixes and improvements
|
||||||
|
to the RIOT codebase. There is new hardware support, new helper functions and
|
||||||
|
many new modules that help with building IoT applications.
|
||||||
|
|
||||||
|
Some of the new features are:
|
||||||
|
|
||||||
|
GCOAP DTLS
|
||||||
|
----------
|
||||||
|
|
||||||
|
The GCOAP CoAP library now supports transport encryption via tinyDTLS.
|
||||||
|
This is a compile-time toggle, so either all requests are encrypted or none.
|
||||||
|
There is already a PR (#16688) that will allow to mix encrypted and unencrypted
|
||||||
|
requests.
|
||||||
|
|
||||||
|
FIDO2 support
|
||||||
|
-------------
|
||||||
|
|
||||||
|
We now have an implementation of the Fast Identity Online 2 (FIDO2) specification.
|
||||||
|
With this you can use any RIOT device with USB support as an authenticaton token
|
||||||
|
similar to the YubiKey.
|
||||||
|
|
||||||
|
RPL-over-BLE
|
||||||
|
------------
|
||||||
|
|
||||||
|
The 6LoWPAN over Bluetooth Low Energy module has gained support for the RPL
|
||||||
|
routing protocol. With this it's now possible to set up IPv6 based mesh networks
|
||||||
|
over BLE on chips supported by the Nimble Bluetooth stack.
|
||||||
|
|
||||||
|
GNRC TCP
|
||||||
|
--------
|
||||||
|
|
||||||
|
RIOT's native GNRC network stack now has support for the TCP protocol via the
|
||||||
|
socket API. With this you can switch between LWIP and GNRC without changing your
|
||||||
|
application.
|
||||||
|
|
||||||
|
DHCPv6 relay agent
|
||||||
|
------------------
|
||||||
|
|
||||||
|
The DHCP module can now act as a relay, forwarding DHCPv6 requests for
|
||||||
|
multihop-operation.
|
||||||
|
|
||||||
|
DHCPv6 IA_NA support
|
||||||
|
--------------------
|
||||||
|
|
||||||
|
The DHCPv6 client can now also request non-temporary addresses as an alternative
|
||||||
|
to Stateless Access Autoconfiguration (SLAAC) that is used by default.
|
||||||
|
The feature can be enabled by selecting the `dhcpv6_client_ia_na` module.
|
||||||
|
|
||||||
|
gnrc_ipv6_auto_subnets
|
||||||
|
----------------------
|
||||||
|
|
||||||
|
This new module allows to split a large IPv6 prefix into smaller ones that can
|
||||||
|
be used to configure downstream interfaces with a prefix.
|
||||||
|
The process can be repeated recursively for a cascading subnet topology.
|
||||||
|
|
||||||
|
This can be a lightweight alternative to DHCPv6 that only relies on router
|
||||||
|
advertisements.
|
||||||
|
|
||||||
|
For more details on this, see the talk on the 2021 RIOT summit.
|
||||||
|
|
||||||
|
UDP benchmark
|
||||||
|
-------------
|
||||||
|
|
||||||
|
The examples section has gained a UDP benchmark.
|
||||||
|
This can be used as a network stress test and is accompanied by a host tool
|
||||||
|
(`dist/tools/benchmark_udp`) that acts as the benchmark server to which the
|
||||||
|
benchmark clients will connect.
|
||||||
|
|
||||||
|
URI template processor
|
||||||
|
----------------------
|
||||||
|
|
||||||
|
URI templates up to level 3 (according to RFC 6570) can now be parsed with this
|
||||||
|
tool.
|
||||||
|
|
||||||
|
riotboot serial flasher
|
||||||
|
-----------------------
|
||||||
|
|
||||||
|
RIOT's native bootloader has gained the ability to load a firmware via UART.
|
||||||
|
This allows to program a board without the need for external programmers, a
|
||||||
|
serial console is enough.
|
||||||
|
|
||||||
|
RTC mem for sam0 and STM32
|
||||||
|
--------------------------
|
||||||
|
|
||||||
|
Many real-time clocks have the ability to store a few bytes in their memory as
|
||||||
|
user data. This memory is retained across reboots and deep sleep.
|
||||||
|
|
||||||
|
We now have an interface for this feature and implemented it on SAM L21,
|
||||||
|
SAM D5x/E5x and STM32.
|
||||||
|
|
||||||
|
LWIP improvements
|
||||||
|
-----------------
|
||||||
|
|
||||||
|
The alternative LWIP network stack can now make use of multiple interfaces.
|
||||||
|
Initialisation is done using the new XFA (cross-file array) feature so new
|
||||||
|
drivers can be added by only adding a single file.
|
||||||
|
|
||||||
|
Advanced topologies in ZEP dispatcher
|
||||||
|
-------------------------------------
|
||||||
|
|
||||||
|
With `socket_zep` and the ZEP dispatcher it is possible to simulate a virtual
|
||||||
|
IEEE 802.15.4 network with `native` nodes.
|
||||||
|
ZEP dispatcher has now gained support for lossy connections that make this
|
||||||
|
simulation behave closer to reality.
|
||||||
|
|
||||||
|
There are also PRs pending to automatically generate such topologies (#16889)
|
||||||
|
and to hook up the ZEP dispatcher to the foren6 network visualizer (#16879).
|
||||||
|
|
||||||
|
RIOT_VERSION_CODE macro
|
||||||
|
-----------------------
|
||||||
|
|
||||||
|
We have added a `RIOT_VERSION_CODE` macro that can be used by external
|
||||||
|
modules / boards to check against which RIOT version it is compiled.
|
||||||
|
|
||||||
|
This allows to react to API changes if the module is built against different
|
||||||
|
versions of RIOT.
|
||||||
|
|
||||||
|
gnrc_netif_ipv6_wait_for_global_address()
|
||||||
|
-----------------------------------------
|
||||||
|
|
||||||
|
For apps that want to connect to a remote server, send some data and then go back
|
||||||
|
to sleep, there is now the new `gnrc_netif_ipv6_wait_for_global_address()` function.
|
||||||
|
|
||||||
|
This function blocks until a global address has been configured (e.g. via router
|
||||||
|
advertisement) or a timeout happens.
|
||||||
|
So no more guessing if a connection can yet be established or if the interface is
|
||||||
|
not configured yet.
|
||||||
|
|
||||||
|
This feature depends on the `gnrc_netif_bus` module.
|
||||||
|
|
||||||
|
netutils_get_ipv6()
|
||||||
|
-------------------
|
||||||
|
|
||||||
|
This simple function can parse a IPv6 address from a string.
|
||||||
|
But that's not all - if the `sock_dns` module is enabled, the string can also
|
||||||
|
be a hostname which will then be resolved.
|
||||||
|
|
||||||
|
This provides a small and simple alternative to `getaddrinfo()` that can be used
|
||||||
|
by shell commands and applications alike.
|
||||||
|
|
||||||
|
gnrc_icmpv6_echo corruption detection
|
||||||
|
-------------------------------------
|
||||||
|
|
||||||
|
On Linux the `ping` command from iputils has the neat feature that it fills the
|
||||||
|
payload with of the ICMP echo request with a pattern that is then echoed back by
|
||||||
|
the receiver.
|
||||||
|
|
||||||
|
That means it can detect if the payload got corruped on the way, e.g. by broken
|
||||||
|
fragmentation or other errors.
|
||||||
|
|
||||||
|
The RIOT `ping` command now also implements this feature that lets you easily
|
||||||
|
detect if something broke along the way.
|
||||||
|
|
||||||
|
New Hardware Support
|
||||||
|
--------------------
|
||||||
|
|
||||||
|
In this cycle we have seen the addition of three new MCU families!
|
||||||
|
Our latest additions are the Raspberry Pi RP2040 and the GD32VF103 RISC-V MCU
|
||||||
|
from GigaDevice.
|
||||||
|
|
||||||
|
Both only have very basic support so far (only GPIO, UART and timers), which
|
||||||
|
still leaves many low hanging fruits for adding peripheral drivers.
|
||||||
|
Patches welcome!
|
||||||
|
|
||||||
|
The nRF9160 is closer to it's nRF52 siblings, but brings GPS and LTE-M/NB-IoT
|
||||||
|
peripherals. While we are not there yet, there is ongoing work to also support
|
||||||
|
these in RIOT.
|
||||||
|
|
||||||
|
The ATxmega family of 8-bit MCUs can now make use of the EBI interface to use
|
||||||
|
external memory. The new XMEGA-A1 Xplained already makes use of this feature.
|
||||||
|
|
||||||
|
On the STM32 side we have now support for the `nucleo-wl55jc` and it's LoRa
|
||||||
|
transceiver.
|
||||||
|
The IEEE 802.15.4 / BLE radio on the STM32WB family is however still waiting
|
||||||
|
for a driver.
|
||||||
|
|
||||||
|
The common LM75 family of temperature drivers is now supported by RIOT.
|
||||||
|
|
||||||
|
The ethernet driver for the SAM E5x line of MCUs is now stable.
|
||||||
|
|
||||||
|
The sub-MAC layer that implements common MAC features for IEEE 802.15.4 radios
|
||||||
|
has again seen many improvements.
|
||||||
|
It is currently used by the nRF52 and CC2538 line of MCUs.
|
||||||
|
|
||||||
|
API changes
|
||||||
|
-----------
|
||||||
|
|
||||||
|
The `spi_acquire()` no longer returns an error code but will throw an assertion
|
||||||
|
if called with the wrong parameters.
|
||||||
|
This allows to speed up SPI operations a bit as SPI parameters are usually fixed
|
||||||
|
at compile time.
|
||||||
|
|
||||||
|
The `gnrc_netdev_default` was replaced by the network stack agnostic
|
||||||
|
`netdev_default` module.
|
||||||
|
|
||||||
|
For now `gnrc_netdev_default` remains an alias for `netdev_default`, but it will
|
||||||
|
be removed in a future release.
|
||||||
|
|
||||||
