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.

477a4a7178 rdc: duplicate packets: Factor out detection code 
The code detecting duplicate packets in the RDC layer had been copied into most
RDC implementations. Factor it out into a new mac-sequence module in order to
have a single instance of this code.

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.

b31e84649a If the 6lowpan layer is currently reassembling a packet, and a non-fragmented packet comes along, this is a sign that one of the fragments were lost (as they normally would arrive back-to-back, in sequence).

c67c048cac Clean up setting channel and CCA-threshold for CC2420 based motes. 
The CCA-threshold now defaults to -46 which give better simulation
results and typically also better experimental results.
This adjustment is also needed due to commit 0a13f99 in mspsim. As
promised in https://github.com/mspsim/mspsim/pull/18 it broke the
regression tests.

0aa448f190 6lowpan fragmentation bugfix: the 6lowpan code had an unfortunate 
interaction with the behavior of the rdc layer. If the first packet of a
fragment transmission was lost, the remaining packets would get dropped
on reception. Moreover, the reception code contained a bug that
sometimes would cause fragments to be misidentified as fragments. Taken
together, these problems would result in a pathelogical network
breakdown if too many fragmented packets would occur simultaneously.

b8c0f2de6c cpu/native: Add file-backed simulated EEPROM to native cpu. 
This patch removes a defunct EEPROM implementation from the native
platform and provides a new EEPROM implementation for the native cpu.
The previous implementation appears to be vestigal.

This is useful for testing code which uses the EEPROM without running
the code on the actual hardware.

By default the code will create a new temporary file as the EEPROM
backing, reinitializing each time. If you would like to preserve the
EEPROM contents or specify a specific EEPROM file to use, you can set the
`CONTIKI_EEPROM` environment variable to the name of the EEPROM file you
wish to use instead. If it already exists, its contents will be used.
If it does not already exist, it will be created and initialized by
filling it with `0xFF`---just like a real EEPROM.

A new example is also included, which was used to verify the correctness
of the implementation. It can easily be used to verify the EEPROM
implementations of other targets.

28a1e40ebd core/lib/settings: Generalized Settings Manager to work on any platform 
This commit moves the Settings Manager from the AVR codebase
into the Contiki core library. Any platform that implements
the Contiki EEPROM API can now use the Settings Manager's
key-value store for storing their persistent configuration info.

The Settings Manager is a EEPROM-based key-value store. Keys
are 16-bit integers and values may be up to 16,383 bytes long.
It is intended to be used to store configuration-related information,
like network settings, radio channels, etc.

 * Robust data format which requires no initialization.
 * Supports multiple values with the same key.
 * Data can be appended without erasing EEPROM.
 * Max size of settings data can be easily increased in the future,
   as long as it doesn't overlap with application data.

The format was inspired by the [OLPC manufacturing data format][].

Since the beginning of EEPROM often contains application-specific
information, the best place to store settings is at the end of EEPROM
(the "top"). Because we are starting at the end of EEPROM, it makes
sense to grow the list of key-value pairs downward, toward the start of
EEPROM.

Each key-value pair is stored in memory in the following format:

Order    | Size     | Name         | Description
--------:|---------:|--------------|-------------------------------
       0 |        2 | `key`        | 16-bit key
      -2 |        1 | `size_check` | One's-complement of next byte
      -3 |   1 or 2 | `size`       | The size of `value`, in bytes
-4 or -5 | variable | `value`      | Value associated with `key`

The end of the key-value pairs is denoted by the first invalid entry.
An invalid entry has any of the following attributes:

 * The `size_check` byte doesn't match the one's compliment of the
   `size` byte (or `size_low` byte).
 * The key has a value of 0x0000.

c0a693672c core/net: Added support for "bridge mode". 
"Bridge mode" allows devices to more easily send 802.15.4 packets as if
they were a different device. It also turns off any packet filtering
that may be implemented at layer 2. It works by allowing
`PACKETBUF_ADDR_SENDER` to be set earlier in the stack.

This is useful for implementing 6LoWPAN-ethernet bridges.

Enabled via setting `NETSTACK_CONF_BRIDGE_MODE` to 1. Disabled by
default.

f145c17039 core/net/resolv: IPv6 and mDNS ("Bonjour") support. Major refactor. 
This patch updates the DNS resolver to support IPv6 and introduces an
improved API for looking up DNS entries. This patch also adds optional
support for mDNS lookups and responses to the DNS resolver.

Here is a quick summary of the changes:

 * Added support for IPv6 lookups.
 * DNS queries now honor record expiration.
 * Added support for mDNS, compatible with "Bonjour".
 * Implemented a new lookup api, `resolv_lookup2()`, which provides
   more information about the state of the record(error, expired,
   looking-up, etc.).

About mDNS/Bonjour Support
--------------------------

This patch adds basic support for mDNS/Bonjour, which allows you to
refer to the name of a device instead of its IP address. This is
incredibly convenient for IPv6 addresses because they tend to be very
long and difficult to remember. It is especially important for
link-local IPv6 addresses, since not all programs support the '%'
notation for indicating a network interface (required on systems with
more than one network interface to disambiguate).

In other words, instead of typing in this:

 * `http://[fe80::58dc:d7ed:a644:628f%en1]/`

You can type this instead:

 * `http://contiki.local/`

Huge improvement, no?

The convenience extends beyond that: this mechanism can be used for
nodes to talk to each other based on their human-readable names instead
of their IPv6 addresses. So instead of a switch on
`aaaa::58dc:d7ed:a644:628f` triggering an actuator on
`aaaa::ed26:19c1:4bd2:f95b`, `light-switch.local` can trigger the
actuator on `living-room-lights.local`.

What you need to do to be able to look up `.local` names on your
workstation depends on a few factors:

 * Your machine needs to be able to send and receive multicast packets
   to and from the LoWPAN. You can do this easily with the Jackdaw
   firmware on an RZUSBStick. If you have a border router, you will need
   it to bridge the mDNS multicast packets across the border.

 * If you are using a Mac, you win. All Apple devices support mDNS
   lookups.

 * If you are using Windows, you can install Apple's Bonjour for Windows
   package. (This may be already installed on your machine if you have
   installed iTunes) After you install this you can easily do `.local`
   lookups.

 * If you are using a Unix machine, you can install Avahi.

The default hostname is set to `contiki.local.`. You can change the
hostname programmatically by calling `resolv_set_hostname()`. You can
change the default hostname by changing `CONTIKI_CONF_DEFAULT_HOSTNAME`.

You may disable mDNS support by setting `RESOLV_CONF_SUPPORTS_MDNS` to
`0`.

---------------------------------

core/net/resolv: `resolv_lookup2()` -> `resolv_lookup()`

Note that this patch should fix several `resolv_lookup()` bugs
that already existed. There were many cases where `resolv_lookup()`
was being called and the IP address ignored, but later code
assumed that the IP address had been fetched... ANYWAY, those
should be fixed now.

---------------------------------

Also updated the Cooja regression test simulation.

1eda821a75 Fixed severe bug in PSOCK_READTO (?) 
Either I found and fixed a severe bug in PSOCK_READTO() or I misunderstood something completely. To me PSOCK_READTO() is supposed to return if either the supplied character was read or if the user supplied buffer is exhausted - sor far so good.

However if the latter occurs up to now PSOCK_READTO() was continuing to process characters already read from the network (aka present in the uIP buffer) in order to check if the supplied character was found there and adjust the return value accordingly. But this means that the character processed this way were lost forever for the caller as the next call to PSOCK_READTO() would continue to read past the characters processed this way.

Therefore I removed that character processing altogether. So now if the user supplied buffer is exhausted before the supplied character is found the next call to PSOCK_READTO() starts exactly where previous call left off.

29391ef9ae Removed uiplib_ip6addrconv() from IPv4 builds. 
While it may very well be beneficial to have explict uiplib_ip4addrconv() and uiplib_ip6addrconv() available for IPv6 builds I'm having a hard time to see the point in uiplib_ip6addrconv() for IPv4 builds.

Unrelated to the above the dispatching of uiplib_ipaddrconv() to either uiplib_ip4addrconv() or uiplib_ip6addrconv() can be accomplished by the C preprocessor only thus avoiding the size/speed overhead of an additional callframe.

5afcbf6fff Makefiles: Allow setting UIP_CONF_IPV6=0 to work as expected. 
Setting UIP_CONF_IPV6 to zero from the make build command line is
something that seems like it should ensure that IPv6 is disabled, but in
fact it actually *enables* IPv6. This seems counter intuitive, so this

68f59113d6 Fix a route lifetime bug 
There is a bug in the current route purge routine which would
result in a route's lifetime getting decremented more than once
during the same pass. This commit fixes it

The bug is documented here:

Adam Dunkels
afe13b22bc Rewrote the uIP IPv6 route handling code. Instead of being nested deeply inside the uip-ds6.c file, the route management code is now in a separate file, uip-ds6-route.c. This file presents a lib/list.h API for the routes, which makes the route list much easier to use. Additionally, the uip-ds6-route.c file adds a callback API that invokes a callback when routes are added and removed. 2012-11-27 23:04:33 +01:00

ec8c7e9be0 Cleanup of the node-id.h files. The node-id.h file contains 
declarations of functions for setting and getting a node ID number, a
functionality that exists on many platforms. Since this functionality
was not considered part of the Contiki core, each platform defined its
own node-id.h file. This commit attempts to clean this up by
collecting the node-id.h into a core/sys/node-id.h file that replaces
the old node-id.h files from the platform directories.

nullrdc-noframer (previously nullrdc) is a null RDC implementation
that does not do any radio duty cycling, does not add any header of its
own to the packets, and does not support link layer addresses.

5585d72c86 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.

37adf130b4 Rewrite of the congestion logic. A node now report it being congested 
when half the transmission queue is full. When a neighbor is heard to
be congested, the rtmetric of that node is inflated to avoid sending
more traffic in its direction.

Fixed problems with beacon intervals: intervals are now not reduced
when a path gets significantly worse, only when they get better.

adamdunkels
d821ba5e22 Added a lifetime for link estimates: if they are too old, they are 
reset so that a new probing period can produce more up-to-date
estimates. Added a congestion mechanism whereby a neighbor can be
marked as being congested for a period of time, during which the ETX
for the neighbor will be artificially inflated.

5eb4a0fe8d Rewrote the initial link estimate logic: link estimates are now

therefore are likely to have better ETXs.

ae88ed04f1 Moved the definition of the channel check rate used by the radio duty 
cycling layer. This definition was previously held in net/mac/mac.h,
with the name MAC_CONF_CHANNEL_CHECK_RATE. But since the rate is used
by the radio duty cycling layer, it makes more sense to change its
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.

eed22a6f3c 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.

* Loss handling. Deals better with losses now.

* Concurrent applications. Each connection now maintains its own
  neighbor table with separated cost to sink estimates for each
  connection.

f6e0b46f38 * Made Chameleon header processing module configurable (CHAMELEON_CONF_MODULE) 
* Removed the unused init function from header processing modules
* Added option CHAMELEON_CONF_WITH_MAC_LINK_ADDRESSES to specify that
  MAC link addresses should be used instead of Chameleon's own encoding
  of sender and receiver. This avoids encoding the link addresses twice
  when the MAC RDC has its own addresses.

e5665fb968 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.
