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.

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.

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

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
