When IPv6 ND kicks in, the packet that caused the ND can either be dropped or saved in a buffer to be send when the NS reply returns. This commit reimplements the buffer management to avoid having one buffer per neighbor, but instead use a buffer pool from which buffers can be allocated for different neighbors.

A simple but substantial change: uIP used the htons()/HTONS() macro
...
functions for converting between host and network byte order. These
names are the de facto standard names for this functionality because
of the original BSD TCP/IP implementation. But they cause problems for
uIP/Contiki: some platforms define these names themselves (Mac OS,
most notably), causing compilation problems for Contiki on those
platforms.
This commit changes all htons to uip_htons instead. Same goes for
htonl, ntohs, and ntohl. All-caps versions as well.

Rewrite of the congestion logic. A node now report it being congested

cycling layer. This definition was previously held in net/mac/mac.h,

name to reflect this. Also, the configuration option should be tied to
the netstack configuration instead.
So the new configuration option is called
NETSTACK_CONF_RDC_CHANNEL_CHECK_RATE.

A number of changes to the collect code:
...
* Added an optional "keep alive" mechanism whereby an idle network is
periodically probed by dummy packets to maintain a recent quality
metric when there is no traffic.
* Bugfix in when new routing metrics should be advertised
* Rewrote the ACK logic so that a queuebuf is not allocated for each
ack, only for those acks generated by the sink node.
* Updated the wrap-around logic for sequence numbers: when a sequence
number wraps, it won't go back to 0. Instead, it wraps to 128. This
allows us to understand when a node has rebooted: when its seqno is <
128, it has recently rebooted.

The recent change turning uip_buf from an array to a pointer seems a quite heavyweight way to have the uip_buf alligned to a 32-bit boundary. Contiki is - still - supposed to be portable across a wide range of toolchains - therefore it i.e. intentionally doesn't use C99 features. From that perspective it seems questionable if all toolchains are able to optimize away the overhead imposed by an "unnecessary" indirection to access uip_buf - and uIP consists mostly of accesses to uip_buf. Even if the future is supposed to bring support for multiple uip_bufs which would turn the uip_buf pointer from a mere workaround to an neceesary element on can still presume that there will be targets with resources limited in a way prohibiting the use of several uip_bufs. So at least for those targets will still be a usecase for a "plain", not indirected uip_buf.
...
Therefore it seems reasonable to allow to stay with the "plain" uip_buf at compile-time.

Two major changes:
...
* Low-power streaming. Experimental support for a low-power mode which
allows rapid exchange of packets with a 16% duty cycle. Does not
seem to function correctly yet though.
* Phase locking. When the phase of a neighbor has been detected, the
sender assumes that the neighbor will keeps it phase and does not
send more strobes than necessary to hit the receiver's channel
check - even if the receiver does not acknowledge the reception of
the strobes when it should have been awake. Instead, the sender
stops strobing and tries again at a later time.

Reworked the locking code, which seems to fix a few bugs caused by the interaction with contikimac. Contikimac performs a CCA check in a preempting rtimer, which requires underlying code to properly call the GET_LOCK() macro. This fix seems to solve most problems, but there may be others left.

Significant rework of the Contiki data collection protocol:
...
* the new version makes use of MAC-layer feedback so that bad paths
can be identified quicker and then avoided.
* the new code uses transport layer ACKs that contain feedback from
the collect protocol: when a packet cannot be forwarded due to lack
of resources, the ACK contains a flag that indicates that the packet
could not be forwarded. ACKs also contain the routing metric of the
sender, which improves agility in face of rapid path changes.
* loop detection and management has been improved: with higher path
metric agility, the system is more prone to short-lived routing
loops. Instead of dropping looping packets, the new version adjusts
the routing metric for the routes that exhibit loops so that the
risk for future loops is reduced.
* make use of packet attributes to inform the MAC layer of how many
times packets should be retransmitted.

Reworked the Rime/Chameleon interface so that packets now always hit Rime before Chameleon. Chameleon is now only called by Rime. This makes packet sniffing easier, and allows for sniffing packets after their header has been processed by Chameleon, thereby making per-packet power profiling much easier to implement

A work-in-progress rework of the Contiki MAC and radio layers. The
...
main ideas are:
* Separates the Contiki low-layer network stack into four layers:
network (e.g. sicslowpan / rime), Medium Access Control MAC
(e.g. CSMA), Radio Duty Cycling RDC (e.g. ContikiMAC, X-MAC), and
radio (e.g. cc2420).
* Introduces a new way to configure the network stack. Four #defines
that specify what mechanism/protocol/driver to use at the four
layers: NETSTACK_CONF_NETWORK, NETSTACK_CONF_MAC, NETSTACK_CONF_RDC,
NETSTACK_CONF_RADIO.
* Adds a callback mechanism to inform the MAC and network layers about
the fate of a transmitted packet: if the packet was not possible to
transmit, the cause of the failure is reported, and if the packets
was successfully transmitted, the number of tries before it was
finally transmitted is reported.
* NULL-protocols at both the MAC and RDC layers: nullmac and nullrdc,
which can be used when MAC and RDC functionality is not needed.
* Extends the radio API with three new functions that enable more
efficient radio duty cycling protocols: channel check, pending
packet, and receiving packet.
* New initialization mechanism, which takes advantage of the NETSTACK
#defines.

ntikiMAC: a new radio duty cycling mechanism that uses a combination
...
of link-layer and MAC-layer mechanisms to achieve a very low power
consumption: during idle listening the radio is switched off between
99.2% and 99.6% of the time. One unicast transmission typically adds
between 0.07% and 1.2% additional radio time, depending on packet
size.
ContikiMAC uses the standard IEEE 802.15.4 message format and adds no
additional headers.
ContikiMAC is simple: it uses periodic two-shot channel sampling
during idle listening to keep the radio on-time down. Transmissions
are done with repeated transmissions until a link-layer ACK is
received.

Bugfix: Active TCP connections in uIP are made by first setting up the
...
TCP connection state, then poll uIP to send out the first SYN. Until
now, however, the SYN was not sent as part of the poll, but at the
first retransmission. This is now fixed.

A new optimization to X-MAC: senders now keep track of when neighbors
...
last were known to be awake. When sending a packet, a sender does not
start to send strobes until the neighbor is expected to be awake. This
reduces power consumption for senders and decreases the contention in
the network as there are less packets in the air. Additionally, the
ACK optimization was improved so that data/ack exchanges now are
more efficient.

Introduced two garbage collection mode: greedy and reluctant.
...
The greedy GC mode attempts to erase as many sectors as possible, and
it is therefore a slow operation, since the flash driver must wait
for about a second after erasing one sector. The former behavior was
to always do a greedy GC if file reservations fails due to lack of space.
The new reluctant GC stops after erasing one sector, and therefore
we often do not have to wait if there is no file system operation
in the time while the sector is being erased. We call the garbage collector
using this mode when removing a file that is not a micro log file, since
the remove function is called recursively for micro log files that are
erased because the corresponding ordinary file is erased.
This change increases the coffee test (examples/sky/test-coffee.c) speed
from 9 to 5 seconds.

With dynamic loading enabled the function ctk_textentry_input_null() lives in the persistent core while the macro CTK_TEXTENTRY() is typically used in loadable modules. So ctk_textentry_input_null() needs to be dynamically resolved.
...
On Win32 dynamic resolving isn't done by patching the dynamically loaded segments. Rather the code generated by the compiler for accessing symbols declared with __declspec(dllimport) is implicitly modified to actually go through pointer dereferenciations. The dynamic linker only initializes this pointers.
But with the symbol ctk_textentry_input_null becoming a pointer to a function it isn't a constant anymore and so it can't be used as initializer element - and thus breaking CTK_TEXTENTRY().
So the only viable solution seems to stick to the inversally available NULL pointer on Win32. But if there's an ugly #ifdef <platform> necessary anyway than it seems resonable to classify ctk_textentry_input_null as the special case and therefore use #ifdef SDCC:
- It saves some bytes on all non-SDCC platforms
- Is matches the exsisting inline documentation

A new experimental network primitive called an 'announcement'. An
...
announcement is an (ID, value) tuple that is disseminated to local
area neighbors. An application or protocol can explicitly listen to
announcements from neighbors. When an announcement is heard, a
callback is invoked.
Announcements can be used for a variety of network mechanisms such as
neighbor discovery, node-level service discovery, or routing metric
dissemination.
Application programs and protocols register announcements with the
announcement module. An announcement back-end, implemented by the
system, takes care of sending out announcements over the radio, as
well as collecting announcements heard from neighbors.

There is problem with the CC2420 driver: under high traffic load the packets often get mangled in the receive FIFO. Not sure why this happens or how to best prevent it. As a temporary workaround, I've added an additional CRC16 check to the incoming packets. This eats two bytes from each packet, but at least protects against the erroneous packets we've seen quite a few of lately. The reception code was also cleaned up, which resulted in a smaller code size.

The cc65 compiler has a bug that doesn't allow to initialize an automatic struct with references to automatic variables. Therefore I changed the timetable used for measuring the timestamping time from automatic to static - which wastes some bytes in the data segment. If this isn't generally acceptable then an #ifdef __CC65__ seems to be the appropriate approach.

This is an initial commit of an implementation of the Chameleon
...
architecture for the Rime stack for Contiki. The Chameleon
architecture separates the header processing from the Rime protocol
logic. Instead of having each protocol create its own part of the
packet header, protocols use packet attributes. Before sending a
packet, a special Chameleon header processing module creates a packet
header from the packet attributes. The same Chameleon module parses
incoming packets and creates packet attributes from the header.
The details are in our SenSys 2007 paper:

Changed the code so that the rtimer is only set from the rtimer (interrupt) code, and not from the non-rtimer code. Removed unused code that was supposed to turn the radio off when a packet for another node was heard (but which didn't really work anyway).

Allow to implement cfs API on preprocessor level. The benefits are:
...
- Less overhead.
- Switching implementations without makefile changes.
- Compatibility with specific declaration needs. (I.e. the cc65 module loader expects the read() function to be defined as fastcall but that contradicts the cfs API declaration.)

Introduced CTK_CONF_WINDOWS.
...
If it is set the behaviour is (supposed to be) as before. Otherwise ctk supports just one window in fullscreen mode: No windows, no borders, no menu, no dialogs, no desktop.
The ctk draw interface stays stable but obviously further code savings are possible by making ctk draw implementations CTK_CONF_WINDOWS aware.
Currently the fullscreen mode doesn't work with mouse support - this is supposed to come later...
