2011-11-09mac80211: add support for control port protocol in AP modeJohannes Berg
This will allow us to support dynamic WEP with 802.1X properly in mac80211 by not encrypting outgoing and accepting unencrypted incoming frames. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2011-11-09mac80211: add helper to free TX skbJohannes Berg
Drivers that need to drop a frame before it can be transmitted will usually simply free that frame. This is currently fine, but in the future it'll be needed to tell mac80211 about this case, so add a new routine that frees a TX skb.

2011-11-09mac80211: simplify mesh frame queue mapping and QoSJavier Cardona
We only need to set the skb queue twice: 1. by the netdev, on local TX. 2. when forwarding a mesh frame. We only need to set the qos header twice: 1. by mac80211, on local TX. 2. when putting a frame on the mpath->frame_queue We also don't need the RA in order to set the proper queue mapping since all mesh STAs are QoS, indicate this and do it once when the frame is received. Also fixes an issue where the QoS header and queue mapping was not set for unicast forwarded frames.

2011-11-09mac80211: check if frame is really part of this BAThomas Pedersen
There was an an implicit assumption that any QoS data frame received from a STA/TID with an active BA session was sent to this vif as part of a BA. This is not true if IFF_PROMISC is enabled and the frame was destined for a different peer, for example. Don't treat these frames as part of a BA from the sending STA.

2011-11-09mac80211: QoS multicast frames have No Ack policyThomas Pedersen
Previously QoS multicast frames had the Normal Acknowledgment QoS control bits set. This would cause broadcast frames to be discarded by peers with which we have a BA session, since their sequence number would fall outside the allowed range. Set No Ack QoS control bits on multicast QoS frames and filter these in de-aggregation code.

2011-11-09mac80211: Avoid filling up mesh preq queue with redundant requestsJavier Cardona
Don't accept redundant PREQs for a given destination. This fixes a problem under high load: kernel: [20386.250913] mesh_queue_preq: 235 callbacks suppressed kernel: [20386.253335] Mesh HWMP (mesh0): PREQ node queue full kernel: [20386.253352] Mesh HWMP (mesh0): PREQ node queue full (...) The 802.11s protocol has a provision to limit the rate of path requests (PREQs) are transmitted (dot11MeshHWMPpreqMinInterval) but there was no limit on the rate at which PREQs were being queued up. There is a valid reason for queuing PREQs: this way we can even out PREQ bursts. But queueing multiple PREQs for the same destination is useless.

2011-11-09mac80211: verify virtual interfaces in driver APIJohannes Berg
The driver is never informed about monitor or AP_VLAN interfaces, so whenever we pass those to it later this is a bug. Verify we don't as there are some cases where this could happen. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2011-11-09net: add wireless TX status socket optionJohannes Berg
The 802.1X EAPOL handshake hostapd does requires knowing whether the frame was ack'ed by the peer. Currently, we fudge this pretty badly by not even transmitting the frame as a normal data frame but injecting it with radiotap and getting the status out of radiotap monitor as well. This is rather complex, confuses users (mon.wlan0 presence) and doesn't work with all hardware. To get rid of that hack, introduce a real wifi TX status option for data frame transmissions. This works similar to the existing TX timestamping in that it reflects the SKB back to the socket's error queue with a SCM_WIFI_STATUS cmsg that has an int indicating ACK status (0/1). Since it is possible that at some point we will want to have TX timestamping and wifi status in a single errqueue SKB (there's little point in not doing that), redefine SO_EE_ORIGIN_TIMESTAMPING to SO_EE_ORIGIN_TXSTATUS which can collect more than just the timestamp; keep the old constant as an alias of course. Currently the internal APIs don't make that possible, but it wouldn't be hard to split them up in a way that makes it possible. Thanks to Neil Horman for helping me figure out the functions that add the control messages. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W.

2011-11-09Bluetooth: Pass full hci_dev struct to mgmt callbacksJohan Hedberg
The current global pending command list in mgmt.c is racy. Possibly the simplest way to fix it is to have per-hci dev lists instead of a global one (all commands that need a pending struct are hci_dev specific). This way the list can be protected using the already existing per-hci dev lock. To enable this refactoring the first thing that needs to be done is to ensure that the mgmt functions have access to the hci_dev struct (instead of just the dev id).
