* mac80211: use fixed broadcast addressJohannes Berg2009-11-181-9/+11
| | | | | | | | | | | | | | | | | The netdev broadcast address cannot change from all-ones so there's no need to use it; we can instead hard-code it. Since we already have an instance in tkip.c, which will be shared if it is marked static const, doing this reduces text size at no data/bss cost. The real motivation for this is, of course, the desire to get rid of almost all uses of netdevs in mac80211 so that auditing their use becomes easier.

* mac80211: Decouple fail_avg stats used by mesh from rate control algorithm.Javier Cardona2009-08-201-0/+18
| | | | | | | | | | | | | | Mesh uses the tx failure average to compute the (m)path metric. This used to be done inside the rate control module. This patch breaks the dependency between the mesh stack and the rate control algorithm. Mesh will now work independently of the chosen rate control algorithm. The mesh stack keeps a moving average of the average transmission losses for each mesh peer station. If the fail average exceeds a certain threshold, the peer link is marked as broken.

* mac80211: redefine usage of the mac80211 workqueueLuis R. Rodriguez2009-08-041-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The mac80211 workqueue exists to enable mac80211 and drivers to queue their own work on a single threaded workqueue. mac80211 takes care to flush the workqueue during suspend but we never really had requirements on drivers for how they should use the workqueue in consideration for suspend. We extend mac80211 to document how the mac80211 workqueue should be used, how it should not be used and finally move raw access to the workqueue to mac80211 only. Drivers and mac80211 use helpers to queue work onto the mac80211 workqueue: * ieee80211_queue_work() * ieee80211_queue_delayed_work() These helpers will now warn if mac80211 already completed its suspend cycle and someone is trying to queue work. mac80211 flushes the mac80211 workqueue prior to suspend a few times, but we haven't taken the care to ensure drivers won't add more work after suspend. To help with this we add a warning when someone tries to add work and mac80211 already completed the suspend cycle. Drivers should ensure they cancel any work or delayed work in the mac80211 stop() callback. Signed-off-by: Luis R. Rodriguez <lrodriguez@atheros.com> Signed-off-by: John W.

* replace net_device arguments with ieee80211_{local,sub_if_data} as appropriateJasper Bryant-Greene2008-08-221-58/+54
| | | | | | | | | | | | | | | | | | | This patch replaces net_device arguments to mac80211 internal functions with ieee80211_{local,sub_if_data} as appropriate. It also does the same for many 802.11s mesh functions, and changes the mesh path table to be indexed on sub_if_data rather than net_device. If the mesh part needs to be a separate patch let me know, but since mesh uses a lot of mac80211 functions which were being converted anyway, the changes go hand-in-hand somewhat. This patch probably does not convert all the functions which could be converted, but it is a large chunk and followup patches will be provided.

* mac80211: fix use of skb->cb for mesh forwardingLuis Carlos Cobo2008-08-071-9/+10
| | | | | | | | | | | | | Now we deal with mesh forwarding before the 802.11->802.3 conversion, thus eliminating a few unnecessary steps. The next hop lookup is called from ieee80211_master_start_xmit() instead of subif_start_xmit(). Until the next hop is found, RA in the frame will be all zeroes for frames originating from the device. For forwarded frames, RA will contain the TA of the received frame, which will be necessary to send a path error if a next hop is not found.

* mac80211: RCU-ify STA info structure accessJohannes Berg2008-03-061-5/+1
| | | | | | | | | | | | | | | This makes access to the STA hash table/list use RCU to protect against freeing of items. However, it's not a true RCU, the copy step is missing: whenever somebody changes a STA item it is simply updated. This is an existing race condition that is now somewhat understandable. This patch also fixes the race key freeing vs. STA destruction by making sure that sta_info_destroy() is always called under RTNL and frees the key.

* mac80211: code for on-demand Hybrid Wireless Mesh ProtocolLuis Carlos Cobo2008-03-061-0/+862
This file implements the on-demand Hybrid Wireless Mesh Protocol, at this moment using hop-count as the metric. When no mesh path exists for a given destination or the mesh path is not active, frames addressed to that destination will be queued and a Path Request frame will be sent. Queued frames will be sent when the path is resolved (usually after reception of a Path Response) or discarded if discovery times out. Path Requests will also be sent to refresh paths that are being used and are close to expiring. Path Errors are sent when a path discovery process triggered by the attempt to forward a frame originated in a different mesh point times out. Path Errors are also sent when a peer link is determined to be unreachable because of high error rates. Multiple destination support in Path Requests and Path Errors and precursors have not been implemented yet.
