RIOT-2019.10 - 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 2019.10 release includes:
- initial support for SUIT firmware updates
- USB CDC-ACM serial communication
- complete rewrite of TI CC110x radio driver
- initial support for IPv6 fragmentation
- DTLS support in the sock networking stack
- complete blockwise messaging for gcoap and nanocoap
- as always, bug fixes and documentation updates
About 460 pull requests, composed of 950 commits, have been merged since the
last release, and about 60 issues have been solved. 57 people contributed with
code in 105 days. Approximately 2000 files have been touched with 129000
insertions and 25000 deletions.

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

RIOT-2019.04 - 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 2019.04 release includes a number of new features including porting of
riotboot to a number of new platforms, 802.15.4 support on the nRF52, and the
ability for firmware to flash images into a separate boot slot. Support for
several new boards and new sensors was added. Additionally, this release
contains a number of bug fixes and test improvements.
About 320 pull requests with about 569 commits have been merged since the last
release and about 40 issues have been solved. 44 people contributed with code
in 88 days. Approximately 825 files have been touched with 32716 insertions
and 5149 deletions.

RIOT-2019.01 - 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 2019.01 release includes a number of new features including DMA support on
all STM32 boards, WiFi with IP connectivity on ESP32 and ESP8266, and riotboot,
a simple bootloader supporting multiple firmware slots, compatible with most Arm
Cortex-M boards supported by RIOT. Support for several new boards and new sensors
was added, as well as for the new CPU architecture Armv8-M (Cortex-M23). Last
but not least, this release contains a number of bug fixes and enhances test
automation.
About 387 pull requests with about 912 commits have been merged since the last
release and about 36 issues have been solved. 54 people contributed with code
in 110 days. Approximately 1554 files have been touched with 176241 insertions
and 50593 deletions.

RIOT-2018.10 - 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 2018.10 release includes new features, like CoAP Resource Directory and
Block2, ESP32 support, rework of I2C interface, EEPROM registry,
Full and Minimal Thread Devices support in OpenThread and compliance of
LoRaWAN 1.0.2 (ABP counters stored in EEPROM). Several boards were introduced.
During the last release the board documentation was migrated from the wiki to
the [RIOT API documentation](https://doc.riot-os.org) to improve the
maintenance of these entries and provide a better user experience when
browsing the documentation. There were also some efforts in grouping some
modules to make them easier to access in the documentation.
There were also some efforts on refactoring, test improvements and bug fixes.
About 392 pull requests with about 914 commits have been merged since the last
release and about 20 issues have been solved. 57 people contributed with code
in 100 days. Approximately 2184 files have been touched with 211964 insertions
and 34806 deletions.

About this release:
===================
The 2018.07 release includes new features, like NimBLE (ble stack),
a MQTT-SN client, SHA-1 based PRNG, an UUID implementation. The RISC-V CPU
architecture support used by the hifive1 board.
Effort was done on refactoring, documentation, test improvements and bug fixes.
During the last release, maintainers contributed by running the automated test
suites on their boards. This gave valuable feedback on the board support state,
test reliability and where to focus effort to make testing easier and more
reliable.
About 380 pull requests with about 675 commits have been merged since the last
release and about 27 issues have been solved. 45 people contributed with code

RIOT-2018.04 - Release Notes
2018-05-11 15:32:01 +02:00
============================
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.

RIOT-2018.01 - 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

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 2018.01 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.

===================================================================================
#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

#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()
#6022: pkg: build order issue

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
2017-10-31 17:22:32 +01:00
#7737: pkg: libcoap is partially broken and outdated
2017-10-27 12:25:58 +02:00
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
--------------------
#5338: xtimer: xtimer_now() not ISR safe for non-32-bit platforms.
#6052: tests: xtimer_drift gets stuck: xtimer_drift application freezes after ~30-200 seconds
#6502: cpu/stm32l1: RTC broken
#7114: xtimer: add's items to the wrong list if the timer overflows between _xtimer_now() and irq_disable()
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
#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
#6442: cpu/native: timer interrupt does not yield thread
#7206: native: race-condition in IPC
other platform related issues
-----------------------------
#1891: newlib-nano: Printf formatting does not work properly for some numeric types: PRI[uxdi]64,
PRI[uxdi]8 and float are not parsed in newlib-nano
#2143: unittests: tests-core doesn't compile for all platforms: GCC build-ins were used in the
unittests which are not available with msp430-gcc
#2300: qemu unittest fails because of a page fault
#4512: pkg: tests: RELIC unittests fail on iotlab-m3
#4560: make: clang is more pedantic than gcc oonf_api is not building with clang (partly fixed by #4593)
#4822: kw2xrf: packet loss when packets get fragmented

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.

#6037: pkg/nanocoap: native build fails on macOS
#6358: arduino uno : xtimer accuracy problem
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
#6442: cpu/native: timer interrupt does not yield thread
other platform related issues
-----------------------------
#1891: newlib-nano: Printf formatting does not work properly for some numeric types: PRI[uxdi]64,
PRI[uxdi]8 and float are not parsed in newlib-nano
#2006: cpu/nrf51822: timer callback may be fired too early
#2143: unittests: tests-core doesn't compile for all platforms: GCC build-ins were used in the
unittests which are not available with msp430-gcc
#2300: qemu unittest fails because of a page fault
#4512: pkg: tests: RELIC unittests fail on iotlab-m3
#4560: make: clang is more pedantic than gcc oonf_api is not building with clang (partly fixed by #4593)
#4694: drivers/lm75a: does not build
#4822: kw2xrf: packet loss when packets get fragmented
#4876: at86rf2xx: Simultaneous use of different transceiver types is not supported
#4954: chronos: compiling with -O0 breaks
#4866: not all GPIO driver implementations are thread safe: Due to non-atomic operations in the drivers
some pin configurations might get lost.
#5009: RIOT is saw-toothing in energy consumption (even when idling)
#5103: xtimer: weird behavior of tests/xtimer_drift: xtimer_drift randomly jumps a few seconds on nrf52
#5361: cpu/cc26x0: timer broken
#5405: Eratic timings on iotlab-m3 with compression context activated

RELEASE 2016.10
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.

Fixed Issues from the last release
==================================
#534: native debugging on osx fails
#2071: native: *long* overdue fixes
#3341: netdev2_tap crashes when hammered
#5007: gnrc icmpv6: Ping reply goes out the wrong interface
#5432: native: valgrind fails
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
### 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
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.
other platform related issues
-----------------------------
#1891: newlib-nano: Printf formatting does not work properly for some numberic
types: PRI[uxdi]64, PRI[uxdi]8 and float are not parsed in newlib-nano
#2006: cpu/nrf51822: timer callback may be fired too early
#2143: unittests: tests-core doesn't compile for all platforms: GCC build-ins
were used in the unittests which are not available with msp430-gcc
#2300: qemu unittest fails because of a page fault
#4512: pkg: tests: RELIC unittests fail on iotlab-m3
#4522: avsextrem: linker sometimes doesn't find `bl_init_clks()`
#4560: make: clang is more pedantic than gcc oonf_api is not building with
clang. (Partly solved by #4593)
#4694: drivers/lm75a: does not build
#4737: cortex-m: Hard fault after a thread exits (under some circumstances)
#4822: kw2xrf: packet loss when packets get fragmented
#4876: at86rf2xx: Simultaneous use of different transceiver types is not
supported
#4954: chronos: compiling with -O0 breaks
#4866: not all GPIO driver implementations are thread safe: Due to non-atomic
operations in the drivers some pin configurations might get lost.
#5009: RIOT is saw-toothing in energy consumption (even when idling)
#5103: xtimer: weird behavior of tests/xtimer_drift: xtimer_drift randomly
jumps a few seconds on nrf52
#5361: cpu/cc26x0: timer broken
#5405: Eratic timings on iotlab-m3 with compression context activated
#5460: cpu/samd21: i2c timing with compiler optimization
#5486: at86rf2xx: lost interrupts
#5489: cpu/lpc11u34: ADC broken
#5603: atmega boards second UART issue
#5678: at86rf2xx: failed assertion in _isr
#5719: cc2538: rf driver doesn't handle large packets
#5799: kw2x: 15.4 duplicate transmits
#5944: msp430: ipv6_hdr unittests fail
#5848: arduino: Race condition in sys/arduino/Makefile.include
#5954: nRF52 uart_write get stuck
#6018: nRF52 gnrc 6lowpan ble memory leak
other issues
------------
#1263: TLSF implementation contains (a) read-before-write error(s).
#3256: make: Setting constants on compile time doesn't really set them
everywhere
#3366: periph/i2c: handle NACK
#4488: Making the newlib thread-safe: When calling puts/printf after
thread_create(), the CPU hangs for DMA enabled uart drivers.
#4866: periph: GPIO drivers are not thread safe
#5128: make: buildtest breaks when exporting FEATURES_PROVIDED var
#5207: make: buildest fails with board dependent application Makefiles
#5390: pkg: OpenWSN does not compile: This package still uses deprecated
modules and was not tested for a long time.
#5520: tests/periph_uart not working
#5561: C++11 extensions in header files
#5776: make: Predefining CFLAGS are parsed weirdly
#5863: OSX + SAMR21-xpro: shell cannot handle command inputs larger than 64
chars
#5962: Makefile: UNDEF variable is not working as documented
#6022: pkg: build order issue

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.

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.

Fixed Issues from the last release
==================================
#534: native debugging on osx fails
#2071: native: *long* overdue fixes
#3341: netdev2_tap crashes when hammered
#5007: gnrc icmpv6: Ping reply goes out the wrong interface
#5432: native: valgrind fails
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
### 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
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.
other platform related issues
-----------------------------
#1891: newlib-nano: Printf formatting does not work properly for some numberic
types: PRI[uxdi]64, PRI[uxdi]8 and float are not parsed in newlib-nano

#4822: kw2xrf: packet loss when packets get fragmented
#4876: at86rf2xx: Simultaneous use of different transceiver types is not
supported
#4954: chronos: compiling with -O0 breaks
#4866: not all GPIO driver implementations are thread safe: Due to non-atomic
operations in the drivers some pin configurations might get lost.
#5009: RIOT is saw-toothing in energy consumption (even when idling)
#5103: xtimer: weird behavior of tests/xtimer_drift: xtimer_drift randomly
jumps a few seconds on nrf52
#5361: cpu/cc26x0: timer broken
#5405: Eratic timings on iotlab-m3 with compression context activated
#5460: cpu/samd21: i2c timing with compiler optimization

#5128: make: buildtest breaks when exporting FEATURES_PROVIDED var
#5207: make: buildest fails with board dependent application Makefiles

RELEASE 2016.04
RIOT-2016.04 - 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 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.

* #4608: tests/xtimer_usleep_until: unstable behaviour
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
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.
* #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
* #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
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"

host system or multiple other native instances), leads to a SEGFAULT
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.
* #4866: not all GPIO driver implementations are thread safe
Due to non-atomic operations in the drivers some pin configurations might get lost
other issues
------------
* #1263: TLSF implementation contains (a) read-before-write error(s)
* #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 up twice in the internal list of the xtimer module.
* #5338: xtimer: xtimer_now() not ISR safe

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.

(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

RIOT-2015.09 - 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: devices based on
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 introduces the GNRC network stack, a completely new, highly
modularized and configurable IPv6/6LoWPAN stack. It also includes xtimer as a
new timer subsystem for accurate short- and long-term timers. Moreover,
peripheral drivers, board, and CPU support has been tidied up and contains
about 50% less duplication in the build system.
About 580 pull requests with about 2,500 commits have been merged since the
last release and 120 additional issues have been solved. 62 people contributed
code in 278 days. 2578 files have been touched with ~320,000 insertions and
~134,000 deletions.

Selected Issues Fixed since the Last Release
============================================
#21: Deal with stdin in bordermultiplex.c
A completely new border router implementation is in place
#715: test_hwtimer_wait fails on native
Fixed by @benoit-canet in #2870
#861: neighbor discovery for 6LoWPAN not working
GNRC implements 6LoWPAN ND in a RFC6775 compliant way
#1753: vtimer_msg test crashes after ~49'20" and
#1449: a removed vtimer might still get called back by hwtimer
vtimer has been replaced by xtimer which does not have these issues
#1870: IPv6 neighbor advertisements are malformed
According to Wireshark (and reference implementations) GNRC sends
well-formed neighbor advertisements
#1964 and #1955: eventual problems with IoT-LAB M3 nodes in the testbed
Solved by new driver versions for UART and radio
#2228: samd21 stack sizes are too small
The stacksize has been adapted in #2229
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.
#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
a rare case and a completely filled up packet buffer was not observed.
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).
#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.
other platform related issues
-----------------------------
#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
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 need 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.

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.

#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.
