RIOT-2018.4 - 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 2018.04 release includes major progress in support for current crypto
|
|
libraries. A lot of work has gone into updating drivers to RIOT's unified
|
|
configuration scheme. Support for ten new boards has been added. In our quest
|
|
to improve and automate testing, many test scripts have been fixed and
|
|
improved, and RIOT's CI now runs many tests on real hardware during its nightly
|
|
build testing. And as usual, many tiny fixes and improvements have been merged.
|
|
|
|
About 390 pull requests with about 1073 commits have been merged since the last
|
|
release and about 54 issues have been solved. 44 people contributed with code
|
|
in 98 days. Approximately 1491 files have been touched with 208426 insertions.

About this release:
|
|
===================
|
|
The 2018.01 release includes major progress in RIOTs network communication
|
|
capabilities, i.e., rewrite of GNRC's neighbour discovery, confirmable messages
|
|
in (g)CoAP, LoRa, and GoMacH as well as updates on CCN-lite and LWIP.
|
|
Furthermore, RIOT contributes to _IKEA-Hacking_ by bringing support for
|
|
the smart home lighting system TRADFRI (note: this will void the warranty).
|
|
Needless to say that this release also adds and updates support for several
|
|
platforms, drivers, and of course lots of enhancements to the documentation
|
|
as well as numerous bug fixes. Last but not least, RIOT now has an official
|
|
code of conduct (https://github.com/RIOT-OS/RIOT/blob/master/CODE_OF_CONDUCT.md)
|
|
|
|
More than 442 pull requests with about 865 commits have been merged since the
|
|
last release and about 96 issues have been solved. 54 people contributed with code
|
|
in 96 days. Approximately 2370 files have been touched with 223970 insertions

About this release:
|
|
===================
|
|
Most notable, this release is bringing RIOT a step closer to supporting
|
|
over-the-air-updates by containing initial support for MCUBoot.
|
|
Furthermore, it adds support for some new platforms (e.g. arduino-mkzero,
|
|
nucleos, and frdm-k22f), drivers (e.g. my9221, apa102, ds1307), and of course
|
|
a large number of bug fixes (e.g. `make buildtest` now working properly,
|
|
various fixes to `xtimer`).
|
|
|
|
About 390 pull requests with about 500 commits have been merged since the last
|
|
release and about 60 issues have been solved. 39 people contributed with code
|
|
in 113 days. 1825 files have been touched with 223454 insertions and 66146 deletions.

Fixed Issues from the last 3 releases (known issues missing in 2017.04 and 2017.07)
|
|
===================================================================================
|
|
#2006: cpu/nrf51822: timer callback may be fired too early
|
|
#4841: xtimer: timer already in the list:
|
|
#4590: pkg: building relic with clang fails.
|
|
#4694: drivers/lm75a: does not build
|
|
#4902: xtimer: xtimer_set: xtimer_set does not handle integer overflows well
|
|
#5128: make: buildtest breaks when exporting FEATURES_PROVIDED var
|
|
#5207: make: buildest fails with board dependent application Makefiles
|
|
#5361: cpu/cc26x0: timer broken
|
|
#5460: cpu/samd21: i2c timing with compiler optimization
|
|
#5489: cpu/lpc11u34: ADC broken
|
|
#5799: kw2x: 15.4 duplicate transmits
|
|
#5928: xtimer: usage in board_init() crashes: some boards use the xtimer in there board_init()
|
|
function. The xtimer is however first initialized in the auto_init module which is executed
|
|
after board_init()
|

|
Known Issues
|
|
============
|
|
Networking related issues
|
|
-------------------------
|
|
#3075: nhdp: unnecessary microsecond precision: NHDP works with timer values of microsecond precision
|
|
which is not required. Changing to lower precision would save some memory.
|
|
#4048: gnrc: potential racey memory leak
|
|
#5016: gnrc_rpl: Rejoining RPL instance as root after reboot messes up routing
|
|
#5230: gnrc ipv6: multicast packets are not dispatched to the upper layers
|
|
#5656: Possible Weakness with locking in the GNRC network stack: For some operations mutexes to the
|
|
network interfaces need to get unlocked in the current implementation to not get deadlocked.
|
|
Recursive mutexes as provided in #5731 might help to solve this problem.
|
|
#5748: gnrc: nodes crashing with too small packet buffer: A packet buffer of size ~512 B might lead
|
|
to crashes. The issue describes this for several hundret nodes, but agressive flooding with
|
|
just two nodes was also shown to lead to this problem.
|
|
#5858: gnrc: 6lo: potential problem with reassembly of fragments: If one frame gets lost the reassembly
|
|
state machine might get out of sync
|
|
#6123: gnrc: crash with (excessive) traffic
|
|
#7035: lwIP: hangs due to sema change after a while

#4499: handle of l2src_len in gnrc_ndp_rtr_sol_handle: Reception of a router solicitation might lead
|
|
to invalid zero-length link-layer addresses in neighbor cache.
|
|
#5005: ndp: router advertisement sent with global address: Under some circumstances a router might
|
|
send RAs with GUAs. While they are ignored on receive (as RFC-4861 specifies), RAs should have
|
|
link-local addresses and not even be send out this way.
|
|
#5122: NDP: global unicast address on non-6LBR nodes disappears after a while: Several issues
|
|
(also see #5760) lead to a global unicast address effectively being banned from the network
|
|
(disappears from neighbor cache, is not added again)
|
|
#5467: ipv6 address vanishes when ARO (wrongly) indicates DUP caused by outdated ncache at router

the stack gets corrupted or a floating point exception occurs.
|
|
#2175: ubjson: valgind registers "Invalid write of size 4" in unittests
|
|
#5796: native: tlsf: early malloc will lead to a crash: TLSF needs pools to be initialized (which is
|
|
currently expected to be done in an application). If a malloc is needed before an application's
|
|
main started (e.g. driver initialization) the node can crash, since no pool is allocated yet.
|

RIOT-2017.07 - 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 microcontrollers, 16-bit
|
|
microcontrollers and 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:
|
|
===================
|
|
This release provides a lot of new features, fixes and enhancements. Among
|
|
these has been a huge cleanup regarding cppcheck and documentation, and we're
|
|
pleased to announce that all remaining doxygen and cppcheck warnings have been
|
|
fixed. We're also proud to present a Virtual File System layer and integration
|
|
of the SPIFFS file system. A lot of work has gone into support for
|
|
STMicroelectronics's Nucleo family, with RIOT now supporting 28 (up from 13)
|
|
Nucleo boards. And as always, there was a lot of under-the-hood cleanup, bug
|
|
fixing and documentation work.

About this release:
|
|
===================
|
|
This release provides a lot of new features, fixes and enhancements. Among others these features
|
|
contain an initial - still experimental - TCP implementation based on the GNRC network stack, support
|
|
for reading from and writing to SD cards, a new power management architecture as well additional third
|
|
party packages such as TweetNaCl, a cryptographic library, and Heatshrink a data compression library
|
|
optimized for embedded real-time systems.
|
|
We added support for new platforms including the Calliope mini, Maple mini, and a couple of STMs
|
|
Nucleo boards. Device support was extended by several new drivers, e.g., for NXP PN532 NFC, Microchip
|
|
MRF24J40 802.15.4 radio (experimental), or Bosch BME280 pressure/humidity/temperature sensor.
|
|
We completely refactored the SPI interface, allowing for internally handled hardware or software chip
|
|
select lines and shared bus usage for multiple devices with different SPI configurations.
|
|
|

Known Issues
|
|
============
|
|
Networking related issues
|
|
-------------------------
|
|
#3075: nhdp: unnecessary microsecond precision: NHDP works with timer values of microsecond precision
|
|
which is not required. Changing to lower precision would save some memory.
|
|
#4048: potential racey memory leak: According to the packet buffer stats, flood-pinging a multicast
|
|
destination may lead to a memory leak due to a race condition. However, it seems to be a rare
|
|
case and a completely filled up packet buffer was not observed.
|
|
#5016: gnrc_rpl: Rejoining RPL instance as root after reboot messes up routing
|
|
#5230: gnrc ipv6: multicast packets are not dispatched to the upper layers
|
|
#5656: Possible Weakness with locking in the GNRC network stack: For some operations mutexes to the
|
|
network interfaces need to get unlocked in the current implementation to not get deadlocked.
|
|
Recursive mutexes as provided in #5731 might help to solve this problem.
|
|
#5748: gnrc: nodes crashing with too small packet buffer: A packet buffer of size ~512 B might lead
|
|
to crashes. The issue describes this for several hundret nodes, but agressive flooding with
|
|
just two nodes was also shown to lead to this problem.
|
|
#5858: gnrc: 6lo: potential problem with reassembly of fragments: If one frame gets lost the reassembly
|
|
state machine might get out of sync
|
|
#6123: gnrc: crash with (excessive) traffic
|
|
|
|
NDP is not working properly
|
|
---------------------------
|
|
#4499: handle of l2src_len in gnrc_ndp_rtr_sol_handle: Reception of a router solicitation might lead
|
|
to invalid zero-length link-layer addresses in neighbor cache.
|
|
#5005: ndp: router advertisement sent with global address: Under some circumstances a router might
|
|
send RAs with GUAs. While they are ignored on receive (as RFC-4861 specifies), RAs should have
|
|
link-local addresses and not even be send out this way.
|
|
#5122: NDP: global unicast address on non-6LBR nodes disappears after a while: Several issues
|
|
(also see #5760) lead to a global unicast address effectively being banned from the network
|
|
(disappears from neighbor cache, is not added again)
|
|
#5467: ipv6 address vanishes when ARO (wrongly) indicates DUP caused by outdated ncache at router
|
|
#5539: Border Router: packet not forwarded from ethos to interface 6
|
|
#5790: ND: Lost of Global IPV6 on node after sending lot of UDP frame from BR
|
|
|
|
Timer related issues

|
|
#4841: xtimer: timer already in the list: Under some conditions an xtimer can end up twice in the
|
|
internal list of the xtimer module
|
|
#4902: xtimer: xtimer_set: xtimer_set does not handle integer overflows well
|
|
#5338: xtimer: xtimer_now() not ISR safe for non-32-bit platforms.
|
|
#5928: xtimer: usage in board_init() crashes: some boards use the xtimer in there board_init()
|
|
function. The xtimer is however first initialized in the auto_init module which is executed
|
|
after board_init()
|
|
#6052: tests: xtimer_drift gets stuck: xtimer_drift application freezes after ~30-200 seconds
|
|
#6331: RTC alarm triggered with 1s delay
|
|
#6419: cpu/cc2538: timer broken
|
|
#6427: xtimer: infinite loop with xtimer_mutex_lock_timeout
|
|
#6502: cpu/stm32l1: RTC broken
|
|
#6542: boards/nucle-f0xx: misconfigured timer configuration (fix in #6494)
|
|
|
|
native related issues
|
|
---------------------
|
|
#495: native not float safe: When the FPU is used when an asynchronous context switch occurs, either
|
|
the stack gets corrupted or a floating point exception occurs.
|
|
#2175: ubjson: valgind registers "Invalid write of size 4" in unittests
|
|
#4590: pkg: building relic with clang fails.
|
|
#5796: native: tlsf: early malloc will lead to a crash: TLSF needs pools to be initialized (which is
|
|
currently expected to be done in an application). If a malloc is needed before an application's
|
|
main started (e.g. driver initialization) the node can crash, since no pool is allocated yet.
|
|
#6145: native: system reboots on SIGTRAP
|

|
|
|
|

RIOT-2016.10 - Release Notes
|
|
============================
|
|
RIOT is a real-time multi-threading operating system that supports a range of
|
|
devices that are typically found in the Internet of Things: 8-bit
|
|
microcontrollers, 16-bit microcontrollers and light-weight 32-bit processors.
|
|
|
|
RIOT is based on the following design principles: energy-efficiency, real-time
|
|
capabilities, small memory footprint, modularity, and uniform API access,
|
|
independent of the underlying hardware (this API offers 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:
|
|
===================
|
|
This release provides a lot of new features as well as it fixes several major
|
|
bugs. Among these new features are the new simplified network socket API
|
|
called sock, the GNRC specific CoAP implementation gcoap and several new
|
|
packages: TinyDTLS, the Aversive++ microcontroller library for robotics, the
|
|
u8g2 graphic library, and nanocoap.
|
|
Using the new sock API an implementation of the Simple Time Network Protocol
|
|
(SNTP) was also introduced, allowing for time synchronization between nodes.
|
|
New platforms include the Arduino Uno, the Arduino Duemilanove, the Arduino
|
|
Zero, SODAQ Autonomo, and the Zolertia remote (rev. B).
|
|
The most significant bug fix was done in native which led to a significantly
|
|
more robust handling of ISRs and now allows for at least 1,000 native
|
|
instances running stably on one machine.
|
|
|
|
About 263 pull requests with about 398 commits have been merged since the last
|
|
release and about 42 issues have been solved. 37 people contributed with code
|
|
in 100 days. 1006 files have been touched with 166500 insertions and 26926
|
|
deletions.

Known Issues

|
============
|
|
Networking related issues
|
|
-------------------------
|
|
#3075: nhdp: unnecessary microsecond precision: NHDP works with timer values
|
|
of microsecond precision which is not required. Changing to lower
|
|
precision would save some memory.
|
|
#4048: potential racey memory leak: According to the packet buffer stats,
|
|
flood-pinging a multicast destination may lead to a memory leak due to
|
|
a race condition. However, it seems to be a rare case and a completely
|
|
filled up packet buffer was not observed.
|
|
#4388: POSIX sockets: open socket is bound to a specific thread: This was an
|
|
inherit problem of the conn API under GNRC. Since the POSIX sockets are
|
|
still based on conn for this release, this issue persists
|
|
#4527: gnrc_ipv6: Multicast is not forwarded if routing node listens to the
|
|
address (might still be fixable for release, see #5729, #5230: gnrc
|
|
ipv6: multicast packets are not dispatched to the upper layers)
|
|
#5016: gnrc_rpl: Rejoining RPL instance as root after reboot messes up routing
|
|
#5055: cpuid: multiple radios will get same EUI-64 Nodes with multiple
|
|
interfaces might get the same EUI-64 for them since they are generated
|
|
from the same CPU ID.
|
|
#5656: Possible Weakness with locking in the GNRC network stack: For some
|
|
operations mutexes to the network interfaces need to get unlocked in
|
|
the current implementation to not get deadlocked. Recursive mutexes as
|
|
provided in #5731 might help to solve this problem.
|
|
#5748: gnrc: nodes crashing with too small packet buffer: A packet buffer of
|
|
size ~512 B might lead to crashes. The issue describes this for several
|
|
hundret nodes, but agressive flooding with just two nodes was also
|
|
shown to lead to this problem.
|
|
#5858: gnrc: 6lo: potential problem with reassembly of fragments: If one frame
|
|
gets lost the reassembly state machine might get out of sync
|
|
|

|
|
addresses and not even be send out this way.
|
|
#5122: NDP: global unicast address on non-6LBR nodes disappears after a while:
|
|
Several issues (also see #5760) lead to a global unicast address
|
|
effectively being banned from the network (disappears from neighbor
|
|
cache, is not added again)
|
|
#5467: ipv6 address vanishes when ARO (wrongly) indicates DUP caused by
|
|
outdated ncache at router
|
|
#5539: Border Router: packet not forwarded from ethos to interface 6
|

RIOT-2016.07 - Release Notes
|
|
============================
|
|
RIOT is a real-time multi-threading operating system that supports a range of
|
|
devices that are typically found in the Internet of Things: 8-bit
|
|
microcontrollers, 16-bit microcontrollers and light-weight 32-bit processors.
|
|
|
|
RIOT is based on the following design principles: energy-efficiency, real-time
|
|
capabilities, small memory footprint, modularity, and uniform API access,
|
|
independent of the underlying hardware (this API offers 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:
|
|
===================
|
|
This release was focused primarily on fixing bugs, but also adds two new
|
|
supported radio transceivers: CC2420 and CC2538.
|
|
This new radio support allows to new interoperability tests with other OS,
|
|
allowing code size comparison and overall network performance for
|
|
platforms based on these radios.
|
|
|
|
About 198 pull requests with about 325 commits have been merged since the
|
|
last release and about 65 issues have been solved. 46 people contributed with
|
|
code in 112 days. 632 files have been touched with 19863 insertions and
|
|
3682 deletions.

Fixed Issues from the last release
|
|
==================================
|
|
#3824: native: gnrc: hardcore pinging crashes.
|
|
#4583: cpp11: clang doesn't allow mutex_t to be used with constexpr All
|
|
cpp11-* tests fail with clang.
|
|
#5388: gnrc_sixlowpan_iphc_nhc: receiving NHC compressed UDP
|
|
packets hits assert in IPv6 (Fixed by #5281).
|
|
|
|
|
|
Known Issues
|
|
==========
|
|
#3075: nhdp: unnecessary microsecond precision NHDP works with timer
|
|
values of microsecond precision which is not required. Changing to lower
|
|
precision would save some memory.
|
|
#3086: Max. packet length for AT86RF2XX
|
|
#4048: potential racey memory leak According to the packet buffer stats,
|
|
flood-pinging a multicast destination may lead to a memory leak due to a
|
|
race condition. However, it seems to be a rare case and a completely filled
|
|
up packet buffer was not observed.
|
|
#5005: ndp: router advertisement sent with global address Under some
|
|
circumstances a router might send RAs with GUAs. While they are ignored
|
|
on receive (as RFC 4861 specifies), RAs should have link-local addresses
|
|
and not even be send out this way.
|
|
#5007: gnrc icmpv6: Ping reply goes out the wrong interface
|
|
#5055: cpuid: multiple radios will get same EUI-64 Nodes with multiple
|
|
interfaces might get the same EUI-64 for them since they are generated from
|
|
the same CPU ID.
|
|
#5230: gnrc ipv6: multicast packets are not dispatched to the upper layers.
|
|
(Fix exists, but was postponed)
|
|
#5390: pkg: OpenWSN does not compile This package still uses deprecated
|
|
modules and was not tested for a long time.

|
|
native related issues
|
|
---------------------
|
|
#495: native not float safe When the FPU is used when an asynchronous
|
|
context switch occurs, either the stack gets corrupted or a floating point
|
|
exception occurs.
|
|
#534: native debugging on osx fails Using valgrind or gdb with a nativenet
|
|
target in OSX leads to "the network" being stuck (gdb) or the whole process
|
|
being stuck (valgrind).
|
|
#334: nativenet crashes when hammered Flood-pinging a native instance
|
|
from more than one host (either multiple threads on the host system or multiple
|
|
other native instances), leads to a SEGFAULT.
|
|
#2071; WIP: native: overdue fixes

#2761: core: define default flags If a thread is created without the
|
|
corresponding flag (CREATE_STACKTEST), the ps command will yield wrong
|
|
numbers for the stack usage.
|
|
#2927: core: Automatically select the lowest possible LPM mode Not all
|
|
available low power modes (LPMs) are implemented for each platform and the
|
|
concept of how the LPM is chosen needs some reconsideration.
|
|
#2967: Makefile.features: location is not relevant for all features Provided

features for the build system should be split up into a board and cpu specific part
|
|
#4488: Making the newlib thread-safe When calling puts/printf after

thread_create(), the CPU hangs for DMA enabled uart drivers.
|
|
#4841: xtimer: timer already in the list Under some conditions an xtimer can end

About this release:
|
|
===================
|
|
This release adds support for two additional network stacks: lwIP and emb6.
|
|
A bunch of additional protocols are now available, P2P-RPL in the GNRC
|
|
network stack, Ethernet-over-Serial (ethos). Murdock, the new, blazing fast
|
|
RIOT CI is now available to significantly speed up code merging procedures.
|
|
|
|
This release also adds support for a number of new boards and sensors and a new
|
|
tool for automated border router setup is now provided which greatly simplifies
|
|
that setup for newbies as well as for old-timers. Last but not least: this
|
|
release includes a number of bug fixes, mostly about stabilizing and enhancing
|
|
the networking capabilities of RIOT.
|
|
|
|
About 470 pull requests with about 1196 commits have been merged since the last
|
|
release and 127 additional issues have been solved. 55 people contributed code
|
|
in 124 days. 1521 files have been touched with ~91700 insertions and ~42200
|
|
deletions.

Fixed Issues from the last release
|
|
==================================
|
|
* #3109: periph/random: random_read should return unsigned int
|
|
* #3970: RPL: Advertise DODAG only over the assigned interface
|
|
* #4462: IPHC/NHC broken between Linux and a RIOT node with a RIOT-based border router in between.
|
|
* #4608: tests/xtimer_usleep_until: unstable behaviour
|
|
|
|
Known Issues
|

|
|
NHDP works with timer values of microsecond precision which is not required. Changing
|
|
to lower precision would save some memory.
|
|
* #3086: Max. packet length for AT86RF2XX
|
|
The size of the link-layer header is not dynamically calculated, but instead the maximum
|
|
size is always assumed.
|
|
* #4048: potential racey memory leak
|
|
According to the packet buffer stats, flood-pinging a multicast destination may lead to a
|
|
memory leak due to a race condition. However, it seems to be a rare case and a
|
|
completely filled up packet buffer was not observed.
|

|
|
* #5388: gnrc_sixlowpan_iphc_nhc: receiving NHC compressed UDP packets hits assert in IPv6
|
|
Fix already provided in #5281, but did not made it into the release due to its complexity
|
|
* #5390: pkg: OpenWSN does not compile
|

|
|
* #3341 and #3824: nativenet crashes when hammered

host system or multiple other native instances), leads to a SEGFAULT
|

RIOT-2015.12 - Release Notes
|
|
============================
|
|
RIOT is a real-time multi-threading operating system that supports a range of
|
|
devices that are typically found in the Internet of Things: 8-bit
|
|
microcontrollers, 16-bit microcontrollers and light-weight 32-bit processors.
|
|
|
|
RIOT is based on the following design principles: energy-efficiency, real-time
|
|
capabilities, small memory footprint, modularity, and uniform API access,
|
|
independent of the underlying hardware (this API offers 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).
|
|
|
|
About this release:
|
|
===================
|
|
This release is mostly a clean-up and bug-fixing release. Besides that, it introduces SAUL,
|
|
the [S]ensor [A]ctuator [U]ber [L]ayer, which offers a unified API to interact with all
|
|
different types of sensors and actuators on RIOT supported hardware. Furthermore, it re-enables
|
|
the support for ICN by integrating CCN-Lite as a package. A lot of new overall documentation was
|
|
added and existing documentation was improved (http://riot-os.org/api/). In addition,
|
|
a Vagrant (https://www.vagrantup.com/) configuration file was added to the RIOT repository in
|
|
order to create reproducible and portable environments that contain all necessary toolchains.
|
|
|
|
About 222 pull requests with about 631 commits have been merged since the last release and 48
|
|
additional issues have been solved. 37 people contributed code in 102 days. 980 files have been
|
|
touched with ~59779 insertions and ~12115 deletions.

Fixed Issues from the last release
|
|
==================================
|
|
|
|
#2724: Add support for serial number passing to CMSIS boards, document it
|
|
Documentation about how to discover and set the serial number of CMSIS-DAP chips is missing
|
|
#3201: Odd length packet snips cause invalid check sum
|
|
If an odd length packet snip occurs in a packet and is not the last snip
|
|
(in the order the packet is supposed to be, not in the list's order)
|
|
in a packet it will generate a wrong check sum.
|
|
|
|
Known Issues
|
|
============
|
|
|
|
network related issues
|
|
----------------------
|
|
#3075: nhdp: unnecessary microsecond precision
|
|
NHDP works with timer values of microsecond precision which is not required. Changing
|
|
to lower precision would save some memory.
|
|
#3086: Max. packet length for AT86RF2XX
|
|
The size of the link-layer header is not dynamically calculated, but instead the maximum
|
|
size is always assumed.
|
|
#3970: RPL: Advertise DODAG only over the assigned interface
|
|
gnrc_rpl seems to multicast DIOs over all interfaces, though gnrc_rpl_init expects an
|
|
interface as parameter and sets the RPL-nodes multicast address only for that interface.
|
|
#4048: potential racey memory leak
|
|
According to the packet buffer stats, flood-pinging a multicast destination may lead to a
|
|
memory leak due to a race condition. However, it seems to be a rare case and a
|
|
completely filled up packet buffer was not observed.
|
|
#4462: IPHC/NHC broken between Linux and a RIOT node with a RIOT-based border router in between.
|
|
|
|
native related issues
|
|
---------------------
|
|
#495: native not float safe
|
|
When the FPU is used when an asynchronous context switch occurs, either the
|
|
stack gets corrupted or a floating point exception occurs.
|
|
#534: native debugging on osx fails
|
|
Using valgrind or gdb with a nativenet target in OSX leads to "the network"
|
|
being stuck (gdb) or the whole process being stuck (valgrind).
|
|
#3341 and #3824: nativenet crashes when hammered
|
|
Flood-pinging a native instance from more than one host (either multiple threads on the
|
|
host system or multiple other native instances), leads to a SEGFAULT.
|
|
#4608: tests/xtimer_usleep_until: unstable behaviour
|
|
The test starts to output "too large difference" and fails after a random period of time.
|
|
|
|
other platform related issues
|
|
-----------------------------
|
|
#4560: make: clang is more pedantic than gcc
|
|
oonf_api is not building with clang.
|
|
#4583: cpp11: clang doesn't allow `mutex_t` to be used with `constexpr`
|
|
All cpp11-* tests fail with clang.
|
|
|
|
other issues
|
|
------------
|
|
#2761: core: define default flags
|
|
If a thread is created without the corresponding flag (CREATE_STACKTEST),
|
|
the ps command will yield wrong numbers for the stack usage
|
|
#2927: core: Automatically select the lowest possible LPM mode
|
|
Not all available low power modes (LPMs) are implemented for each platform and the
|
|
concept of how the LPM is chosen needs some reconsideration
|
|
#2967: Makefile.features: location is not relevant for all features
|
|
Provided features for the build system should be split up into a board and cpu specific
|
|
part
|
|
#3109: periph/random: random_read should return unsigned int
|
|
The documentation of this function does not match corresponding implementation.
|
|
#4488: Making the newlib thread-safe
|
|
When calling puts/printf after thread_create(), the CPU hangs for DMA enabled uart drivers.

|
----------------------
|

#3075: nhdp: unnecessary microsecond precision
|
|
NHDP works with timer values of microsecond precision which is not
|
|
required. Changing to lower precision would save some memory.
|
|
#3086: Max. packet length for AT86RF2XX
|
|
The size of the link-layer header is not dynamically calculated, but

instead the maximum# size is always assumed.
|
|
#3201: Odd length packet snips cause invalid check sum
|
|
If an odd length packet snip occurs in a packet and is not the last snip
|
|
(in the order the packet is supposed to be, not in the list's order) in a
|
|
packet it will generate a wrong check sum.
|
|
#4048: potential racey memory leak

|
According to the packet buffer stats, flood-pinging a multicast destination
|
|
may lead to a memory leak due to a race condition. However, it seems to be

Sending more than 100 packets per second causes a SEGFAULT in RIOT native.
|
|
#534: native debugging on osx fails
|
|
Using valgrind or gdb with a nativenet target in OSX leads to "the network"

RIOT-2014.12 - Release Notes
|
|
============================
|
|
RIOT is a real-time multi-threading operating system that supports a range of
|
|
devices that are typically found in the Internet of Things: from 8-bit
|
|
microcontrollers to light-weight 32-bit processors.

|
|
compliance).

Fixed Issues from the last release
|
|
==================================
|
|
#426: Interrupt handling on MSP430 is buggy
|
|
Several fixes by @rousselk
|
|
#1798: core: first thread on runqueue is scheduled twice
|
|
Was fixed along with the thread_yield() refactoring
|
|
#1127: Random build fails on OSX
|
|
native is building stable also on OSX now
|
|
|
|
Known Issues
|
|
============
|
|
network related issues
|
|
----------------------
|
|
#21: Deal with stdin in bordermultiplex.c
|
|
Not all supported platforms provide a stdin in the current release.
|
|
However, the implementation of the 6LoWPAN border router won't work
|
|
without stdin.
|
|
#861: neighbor discovery for 6LoWPAN not working
|
|
Duplicate address detection according to RFC 6775 is also missing.
|
|
#1577: ccn-lite: populate does not work with disabled cache
|
|
If cache is set to zero, the chunks cannot be loaded and therefore also not get populated.
|
|
#1870: IPv6 neighbor advertisements are malformed
|
|
According to Wireshark, ICMPv6 neighbor advertisements are malformed (wrong
|
|
checksum or other reasons).
|
|
|
|
native related issues
|
|
---------------------
|
|
#495: native not float safe
|
|
When the FPU is used when an asynchronous context switch occurs, either the
|
|
stack gets corrupted or a floating point exception occurs.
|
|
#499: native is segfaulting on heavy network usage
|
|
Sending more than 100 packets per second causes a SEGFAULT in RIOT native.
|
|
#534: native debugging on osx fails
|
|
Using valgrind or gdb with a nativenet target in OSX leads to "the network"
|
|
being stuck (gdb) or the whole process being stuck (valgrind).
|
|
#715: test_hwtimer_wait fails on native
|
|
The problem appears to be lost signals and depends on the CPU speed.
|
|
#787: reboot not working with open file descriptors on native
|
|
If for example a tap device is in use, the reboot command fails.
|
|
#862: sometimes the tap bridge does not work in native
|
|
Sometimes (rather suddenly) packages are not received by a TAP and won't be
|
|
received even if I reconfigure the bridge.
|
|
|
|
|
|
other platform related issues
|
|
-----------------------------
|
|
#1232: x86 doesn't build on OS X with clang
|
|
Current version of the x86 port doesn't build for OS X with clang.
|
|
#1442: setting channel is not persistent cc2420
|
|
After changing the channel via a shell command, the channel reverts back to an arbitrary
|
|
value. However, this might be only a shell problem.
|
|
#1753: vtimer_msg test crashes after ~49'20"
|
|
dependent on the platform, vtimer stops working after some time.
|
|
#1891: printf formatting does not work properly on some Cortex platforms for 64 bit numbers
|
|
This problem happens mostly for the Newlib nano, which does not support 64 bit integer
|
|
printing, but sometimes happens also with other toolchains.
|
|
#1964 and #1955: eventual problems with IoT-LAB M3 nodes in the testbed
|
|
The shell is sometimes not properly working after a reboot and the PDR is sometimes
|
|
worse than expected.
|
|
#2143: tests.core doesn't compile for all platforms
|
|
For some missing GCC compiler builtins, the unittests do not compile for MSP430
|
|
platforms.
|
|
#2228: samd21 stack sizes are too small
|
|
The application examples/default for example will crash when issuing the txtsnd command
|
|
|
|
other issues:
|
|
--------------
|
|
#1449: a removed vtimer might still get called back by hwtimer
|
|
The timer callback might still fire even after vtimer_remove() was called.
|
|
#2175: valgrind registeres "Invalid write of size 4" in unittests for ubjson
|
|
According to valgrind the stack gets corrupted in UBJSON.

Fixed Issues from the last release
|
|
==================================
|
|
#45: bit field order in the fcf may be wrong
|
|
The CC2420 FIFO expects the IEEE802.15.4 FCF field in reversed bit order.
|
|
With this release the byte order is now handled by the net_if module and
|
|
all device specific handling is done by the driver.
|
|
#82: Setting STATUS_REPLY_BLOCKED thread to STATUS_PENDING though it is not
|
|
handled yet
|
|
In some rare cases the status of a thread might falsely change to
|
|
STATUS_PENDING instead of STATUS_REPLY_BLOCKED.
|
|
#455: sha256 is broken on MSP430
|
|
Fixed.
|
|
#498: native is segfaulting at startup
|
|
Fixed by several PRs (#501, #583, and #588).
|
|
#505: native on FreeBSD is broken
|
|
Fixed by PR #1022.
|

|
|
received even if I reconfigure the bridge.
|
|
#1127: Random build fails on OSX
|

Building for native on OSX often fails - Workaround: build using -B flag,
|
|
e.g.: make -B clean all
|
|
|
|
other platform related issues
|
|
-----------------------------
|
|
#426: Interrupt handling on MSP430 is buggy

Fixed Issues from the last release
|
|
==================================
|
|
#45: bit field order in the fcf may be wrong
|
|
The CC2420 FIFO expects the IEEE802.15.4 FCF field in reversed bit order.
|
|
With this release the byte order is now handled by the net_if module and
|
|
all device specific handling is done by the driver.
|
|
#82: Setting STATUS_REPLY_BLOCKED thread to STATUS_PENDING though it is not
|
|
handled yet
|
|
Pull Request #569 fixed this bug by checking for STATUS_REPLY_BLOCKED in
|
|
msg_receive().
|
|
#455: sha256 is broken on MSP430
|
|
The problem was caused
|
|
|
|
Known Issues
|
|
============
|
|
#21: Deal with stdin in bordermultiplex.c
|
|
Not all supported platforms provide a stdin in the current release.
|
|
However, the implementation of the 6LoWPAN border router won't work
|
|
without stdin.
|
|
#426: Interrupt handling on MSP430 is buggy
|
|
UART and timer handling is still unstable on MSP430 based platforms.
|
|
#495: native not float safe
|
|
When the FPU is used when an asynchronous context switch occurs, either the
|
|
stack gets corrupted or a floating point exception occurs.
|
|
#498: native is segfaulting at startup
|
|
In some cases (about 5-10%) a RIOT native process crashes with a SEGFAULT
|
|
at startup.
|
|
#499: native is segfaulting on heavy network usage
|
|
Sending more than 100 packets per second causes a SEGFAULT in RIOT native.
|
|
#505: native on FreeBSD is broken
|
|
Due to different parameter handling in FreeBSD, native is currently not
|
|
working there.
