state since we are already not standard complaint. This reduces the
nbr discovery messages if nodes talk to each other periodically.

d160943f16 Bug fix: Stop the DAO lifetime timer in RPL instances when released. 
Clearing the memory for an active etimer/ctimer might corrupt the
timer list and cause other timers to be lost or infinite loops. The
DAO lifetime timer is only used when RPL route lifetime is not
infinite but then the timer will cause problems if not stopped.

5e640411f5 core/net/rime/ipolite: stop ctimer and reset queuebuf pointer when canceling old send 
Ipolite is used by netflood and route-discovery modules among others. If a route request is yet to be re-broadcasted and a local route discovery is started (interval == 0), the previous queuebuf used is freed but ctimer and queuebuf pointer is left unchanged. This causes corrupt route requests to be sent, invalid routing tables to be formed, memcmp() on NULL pointer on receive, and other undefined behavior.

24d15ad9a5 core/net/ip: Prevent (tiny) buffer overflow in resolv_found() 
An off-by-one error in resolv_found() could make an strncat() call
overflow by the terminating null byte.

When building with Clang the following warning was shown:

../../../core/net/ip/resolv.c:1458:17: warning: the value of the
      size argument in 'strncat' is too large, might lead to a
      buffer overflow [-Wstrncat-size]
                sizeof(resolv_hostname) - strlen(resolv_hostname));
                ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
../../../core/net/ip/resolv.c:1458:17: note: change the argument to
      be the free space in the destination buffer minus the
      terminating null byte
                sizeof(resolv_hostname) - strlen(resolv_hostname));
                ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
                sizeof(resolv_hostname) - strlen(resolv_hostname) - 1

b441901321 IPv6 host adds prefixes successfully but return always NULL 
In Neighbor Discovery Protocol, when IPv6 host adds a prefix (coming from PIO) but it is always failing whatever if is successfully add in prefix table. The reason comes from the fact that the function uip_ds6_prefix_add in host version always return NULL. This is opposite of the specification of the router version.

65ef375bdb Re-create a routing table entry if the next hop is changed. 
The next-hop address did not get updated in the routing table
in case an entry for the destination already existed.

This patch resolves the issue by removing the entry and
having it re-created from scratch.

The issue causes a routing error triggering reconstruction of
the DODAG through version increase.

In case of somewhat frequent downward traffic in not (yet) stabilized DODAG
a vicious circle is formed: unstable topology means churn, downward
routing under churn causes reconstruction of DODAG. In this situation
the network does not have chance to stabilize.

We encountered a constant churn caused by this bug
in a network of 50 nodes and a periodic traffic (a packet every 5
seconds) generated at the root.

More info and a PCAP demonstrating the issue can be found here:

1058ea986a Changed the parameter 'char * data' of process_start to the 
type process_data_t. This was an artifact when the choice was
made to use the void * type for the data parameter in processes.

Changed parameter 'void * data' of process_post_synch to
process_data_t for consistency.

Checked all the uses of process_start() in contiki and fixed casts
of the data parameter.

a96dc90250 [SPI] Make SPI_FLUSH() more versatile 
Currently the SPI driver in core/ sets `SPI_FLUSH()` to be a single read
of the spi RX buffer. This is fine for many microcontrollers, but newer
platforms like the CC2538 have a multi-byte FIFO for the RX buffer. In
that case, a single read is not guaranteed to flush the RX. This commit
allows `SPI_FLUSH()` to be platform dependent if needed, but doesn't
change for platforms where it works.

d1822b5880 collect: making some protocol parameters configurable by COLLECT_CONF_ style defines 
TTL (which has a rather low default of 15), MAC level retransmissions,
overall number of retransmissions, and the header bits dedicated to these
were all fixed in the collect.h and collect.c, without a simple way to
override them.
Extracted these as COLLECT_CONF_ parameters, keeping defaults as they were
before.

9846216358 leds: Add the leds_set() function 
The leds_set() function is added on top of leds_arch_set() in order to have a
means of displaying a pattern on a set of LEDs, while keeping the ENERGEST
information up to date, which would be missing with a direct call to
leds_arch_set().

7f48057b9e leds: Fix the API 
The leds API did not work in some cases. E.g. with the following sequence:
  leds_off(LEDS_ALL);
  leds_toggle(LEDS_GREEN);
  leds_off(LEDS_ALL);
the green LED was remaining on after the last call.

This was caused by the toggle feature made synonymous with the invert feature,
although it is unrelated. leds_toggle() is indeed supposed to toggle an LED,
while leds_invert() is supposed to change the active level of an LED. However,
all users of leds_invert() actually meant leds_toggle(), and the invert feature
does not make sense in this module because it is not handy due to successive
calls to leds_invert() changing the intended behavior, and hardware active
levels should be managed in leds_arch_set() (e.g. by XORing the passed value
with a hardware-specific constant before setting the output levels of the pins).

Consequently, this change:
 - removes the leds_invert() function,
 - makes leds_toggle() behave as expected relatively to leds_off() / leds_on(),
 - sanitizes the code in the leds module.

4deba89f81 rdc: duplicate packets: Keep only the last sequence number for each address 
According to IEEE 802.15.4e (§6.4.3.9), in order to detect duplicate received
MAC-layer frames, only the most recently received frame's sequence number needs
to be stored for each unique device address. Doing so limits the possible false
duplicate packet detections to a single sequence number. This also allows to
keep the last sequence number of more device addresses for the same value of
MAX_SEQNOS.

14db3382af csma: Initialize sequence number with random value 
According to IEEE 802.15.4 (§5.1.6.1, §6.4.2), the MAC sequence numbers should
be initialized to random values. This was already the case in
framer-802154.c:create(), but not in csma.c:send_packet(), sometimes causing
false detections of duplicate MAC-layer packets in other devices when a device
was restarted too quickly. This patch decreases the probability of such an
event.

faff1c2a7e Preliminary support for RPL node types. This change allows a node to be in any of three given types: 
* Mesh: this is the normal case. Nodes route data on behalf of others and the node can be reached via a DAO route.
* Leaf: the node does not route data on behalf of others, but others can route data to the node (it has a RPL DAO route).
* Feather: this is a new type of node. A feather node routes data on behalf of others, but does not install DAO routes in the network. Feather nodes allow having a larger number of nodes than the RPL network can sustain in terms of routing tables.

This commit introduces the RPL node types and the feather mode, but does not add support for the leaf node type.

61ea7fbb1c RPL DAO timers and management: 
* Added a DAO lifetime timer that sends out a new DAO after half the lifetime of the DAO. This allows implementing DAO route soft state that avoids routing tables in the network keeping stale routes for ever.
* Added ways to schedule a new DAO transmission as well as cancelling an active DAO transmit timer, which makes it possible to do nodes that don't send DAOs.
