2012-11-14iwlwifi: fix monitor mode FCS flagJohannes Berg
When the firmware is in SNIFFER mode, it leaves the FCS at the end of frame. Not telling mac80211 means it won't add the right flag to the radiotap header and that confuses wireshark. Since mac80211 doesn't have a per-packet flag, set the HW flag dynamically. This works as the monitor vif can only be present in the driver by itself.

2012-11-09Bluetooth: Fix error status when pairing failsPaulo Sérgio
When pairing fails due to wrong confirm value, the management layer doesn't report a proper error status. It sends MGMT_STATUS_CONNECT_FAILED instead of MGMT_STATUS_AUTH_FAILED. Most of management functions that receive a status as a parameter expects for it to be encoded as a HCI status. But when a SMP pairing fails, the SMP layer sends the SMP reason as the error status to the management layer. This commit maps all SMP reasons to HCI_ERROR_AUTH_FAILURE, which will be converted to MGMT_STATUS_AUTH_FAILED in the management layer.

2012-11-09Bluetooth: Fix having bogus entries in mgmt_read_index_list replyJohan Hedberg
The mgmt_read_index_list uses one loop to calculate the max needed size of its response with the help of an upper-bound of the controller count. The second loop is more strict as it checks for HCI_SETUP (which might have gotten set after the first loop) and could result in some indexes being skipped. Because of this the function needs to readjust the event length and index count after filling in the response array.

2012-10-30ath9k: Test for TID only in BlockAcks while checking tx statusSven Eckelmann
The ath9k xmit functions for AMPDUs can send frames as non-aggregate in case only one frame is currently available. The client will then answer using a normal Ack instead of a BlockAck. This acknowledgement has no TID stored and therefore the hardware is not able to provide us the corresponding TID. The TID set by the hardware in the tx status descriptor has to be seen as undefined and not as a valid TID value for normal acknowledgements. Doing otherwise results in a massive amount of retransmissions and stalls of connections. Users may experience low bandwidth and complete connection stalls in environments with transfers using multiple TIDs. This regression was introduced in b11b160defc48e4daa283f785192ea3a23a51f8e ("ath9k: validate the TID in the tx status information").

2012-10-29ath9k: fix stale pointers potentially causing access to free'd skbsFelix Fietkau
bf->bf_next is only while buffers are chained as part of an A-MPDU in the tx queue. When a tid queue is flushed (e.g. on tearing down an aggregation session), frames can be enqueued again as normal transmission, without bf_next being cleared. This can lead to the old pointer being dereferenced again later. This patch might fix crashes and "Failed to stop TX DMA!" messages.
