Introduction of RPL non-storing mode#1404
Conversation

Due to exams and stuff there had been no progression on this PR in the last days. Although I thought of some restructuring - a new update is coming shortly. |
|
Implementation is now working with minus one thread :) However the two problems 1) integration of both storing/non-storing in one folder and 2) checksum stay the same. I will work on both shortly. Also rebased with master according to new kernel-pids etc. |
|
Everything is fixed. I will squash and rebase. |
|
At several places there are code fragments (lines) commented out via |
|
Sure thing. They will be gone after rebase. |

I think something like rpl_is_root() would be a more appropriate name.

It's slightly unrelated to this PR, but can you fix the Edit: removing the actual file name after |

Obey coding conventions also regarding the maximum number of characters per line. |

Nope, the old version was the right RIOT style.

Should I wait for more or is this all? :)
This implementation is based on RFC 6550 with addition of RFC 6554 (Source Routing Header for RPL). Both can be found under the following links: - http://tools.ietf.org/html/rfc6550 - http://tools.ietf.org/html/rfc6554 The PR provides basic functionality for handling and forwarding packages in non-storing mode. In addition the structure of the previous implemented RPL storing mode is now revised, so that readability and modularity is increased. The following features are implemented: - building function for a SRH and integration in common packets - source-route build algorithm based on the structure of the DODAG - an RPL-based interpretation of the SRH and removal at destination - new structure for RPl-module with extracted beaconing-functionality - leaf nodes are now supported There are some missed goals and should be included in future updates: - building a common routing table structure for different types of routing protocols - routing tables are statically assigned via source code, future update should have an optional variable at build-time, which sets the size of the routing table depending on the desired functionality of a node in the network (root, node, leaf)

Awesome - thanks for all the help :) |

congrats! |
In PR RIOT-OS#1404 addr_str was renamed to addr_str_mode, but at some places it was still referenced as addr_str. When enabling debug messages, the compiler complains.
As a result of PR RIOT-OS#1404, entries will not be added to the routing table when running in storing mode, although it is supposed to do so. You can verify by running rpl_udp and call *route* on the dodag-root. This PR fixes the wrong offset calculation.
This is the first commit for discussion. It works - but e.g. the checksum in UDP-packages is wrong because the length is zero (which it is not btw). In addition the design decisions concerning messages sending/relaying may be discuss-able - but I think they are as noninvasive as the network stack would allow them to be.
At last - the proposed fixes concerning storing/non-storing mode files with the same declaration-base in one directory from @Kijewski does not work. (Both - excluding files or moving them to a sub-directory) But I will see more into it. Maybe someone can help.
