This series of patches provides support for (pre) IEEE 802.11s mesh interfaces. Current features include mesh discovery, peer link establishment and on-demand HWMP path discovery. This is the second round of patches incorporating the comments from Johannes Berg and others. The main changes with the first set of patches are: - We are now using airtime link metric, instead of hop count. - Mesh peer link table has been discarded, integrating the necessary attributes directly on struct sta_info. - We no longer use directily rtnetlink for mesh peer link and mesh paths operation, and use nl80211 instead. - We now support mesh network in scan. The part interacting with wext is a bit ugly but works well. I just read the mail from Johannes with a different approach and will consider it. The pid rate control algorithm has been modified to provide an estimated transmission error, probability, necessary for the airtime link metric, and a to call mesh_peer_link_broken() if it detects a sta is no longer reachable. I would like to point out that it looks like we can get duplicate sta_entries, or more entries than the maximum allowed, if stas are added at the same time through normal network behaviour and manual operation through nl80211. Please correct me if I am wrong or if it is just that no interface type is supposed to allow both kinds of additions. The code has been tested in a 12-node testbed and has proved to be stable and functional. We would like to get it integrated as soon as possible so it can get more widespread testing and (hopefully) contributions. Unfortunately we have run out of funds for this project (we are looking for sponsors!) so work on the project from our side might slow down. At the very least, we are commited to fixing bugs and tracking changes introduced by newer versions of the 11s draft. The only supported driver right now is zd1211rw, but changes in the driver for mesh functionality are minimal (for the zd1211rw driver most changes were just to provide missing functionality such as beaconing support), so we expect a wide array of devices to be supported soon. The patches are to be applied on top of wireless-2.6/everything HEAD. Even though I am sure there will be some issues, it would be great if we could integrate this as soon as possible to make it easier for other people to collaborate and to make my life a bit easier :-) For more information, please visit: http://o11s.org/devel Enjoy, Luis Carlos Cobo - To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
