bfd7e5f25b Fixed a few bugs in the route handling code. While bughunting, rewrote parts of the code to make its intention clearer. Also added a bunch of comments to make the logic of the code more evident. 2013-08-19 17:48:32 +02:00

8dc4e46968 Check if the nexthop neighbor for a given route has disappeared. If so, we drop the route too. If we happen to be the RPL root, we also initiate a global repair as the neighbor may moved. 2013-08-19 17:48:32 +02:00

e5a6565137 Loop detection via DAO: if we get a DAO from a parent, that parent thinks we are its parent. We poison it and recalulate our parents. 2013-08-19 17:48:32 +02:00

34119b7ef2 Poor man's loop reparation: reset the DIO timer and hope the neighbor learns a better route. 2013-08-19 17:48:32 +02:00

d830e9df3f Implement forwarding error handling: if a packet changes direction, we set the FWD_ERR flag. If we see the FWD_ERR flag, we drop the route that we sent it to. If we are the root node, we also initiate a global repair. 2013-08-19 17:48:31 +02:00

ff093a2b50 Removed now unused per-module neighbor table size configs. Use NEIGHBOR_CONF_MAX_NEIGHBORS instead. 2013-08-19 17:48:30 +02:00

c3f62b24c8 Moved ETX management from neighbor-info to rpl-of-etx. Avoids conversions between different fixed point representations, and simplifies neighbor management. Makes more clear how default-ETX and noack-ETX actually affect the rank. Removed neighbor-info and neighbor-attr. 2013-08-19 17:48:30 +02:00

c50d10aa53 Make RPL use neighbor tables. RPL locks the neighbor used as preferred parent. 2013-08-19 17:48:30 +02:00
Simon Duquennoy
09d26f8060 Make uip-ds6-route use neighbor table. Instead of storing a global list of routing entries that contain both the next hop and the destination, we have a separate list of reachable destination for each neighbor in the global table. 2013-08-19 17:48:30 +02:00

ec609b49eb Make DS6 neighbors use neighbor-table, and move all DS6 neighbor management from uip-ds6 to a new uip-ds6-neighbor module. 2013-08-19 17:48:30 +02:00

5a1d8d8006 Make phase module use neighbor-table. 2013-08-19 17:48:29 +02:00
Simon Duquennoy
cfb3bbdad9 Added new neighbor-table module, a centralized place where to store all data about neighbors, indexed by link-layer address. Meant for use in other Contiki modules such as rpl, ds6, ds6-route, phase, neighbor-info. 2013-08-19 17:48:29 +02:00

f5307fc01e Bugfix: must set the SICSLOWPAM_MAX_MAC_TRANSMISSIONS attribute after clearing the buffer, otherwise it will not be used for outoing packets. 2013-08-11 14:27:21 +02:00
Adam Dunkels
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.

512a339c50 Bugfix: DIOs with infinite ranks should not be ignored as they are used by RPL as a signal by nodes that have lost their routes. Instead of ignoring them, we should send out our latest information to let the node with infinite rank find their way into the network again. 2013-07-26 12:38:25 +02:00

09f30e875d Bugfix: when a CSMA callback is received, we should remove the packet 
that was transmitted and not just the first packet that happens to be on
the output queue.
