2011-06-27mwifiex: restore handling of NULL parametersDan Carpenter
Prior to a5ffddb70c5cab "mwifiex: remove casts of void pointers" the code assumed that the data_buf parameter could be a NULL pointer. The patch preserved some NULL checks but not consistently, so there was a potential for NULL dereferences and it changed the behavior. This patch restores the original behavior.

2011-06-27ath9k: Fix locking issue during tx completionRajkumar Manoharan
The received tx status of aggregated frame without BlockAck may cause deaf state in AR5416 cards. So the driver does a reset to recover. When this happens, we release the pcu_lock before doing a reset as ath_rest acquires pcu_lock. This is ugly and also not atomic. Fixing this addresses the TX DMA failure also. ath_tx_complete_aggr can be called from different paths which takes different variants of spin_lock. This patch also addresses the following warning.

2011-06-27ath9k_hw: Fix false tx hung detection in AR9003 chipsRajkumar Manoharan
The edma based (AR9003 family) chips update tx status descriptors in a common ring buffer for all transmitted frames. Whenever tx interrupt is raised, the descriptors are processed and tx status index is moved. The complete tx stauts ring are updated with beacons tx status when there are no data frames to be sent for a period of time. In this state, transmitting data frames causes the driver to wait for the tx status on an incorrect tx status index though the status was updated by hw properly. The driver detects this condition as a h/w hang and does unnecessary chip resets. This issue was orginally reported in adhoc mode while sending frames after an idle time.

2011-06-27mac80211: reestablish mis-configured existing Rx BA sessionsArik Nemtsov
When forming a Rx BA session, sometimes the ADDBA response gets lost. This leads to a situation where the session is configured locally, but doesn't exist on the remote side. Subsequent ADDBA requests are declined by mac80211. Fix this by assuming the session state of the initiator is the correct one. When receiving an unexpected ADDBA request on a TID with an active Rx BA session, delete the existing one and establish a new session.

2011-06-24iwlagn: don't use CCK rates for P2P interfacesJohannes Berg
P2P interfaces must not use CCK rates, only OFDM rates are allowed. To set this up, we need to set up the broadcast station to start with 6M instead of starting with 1M. Since the interface type can change, also reset the broadcast station when RXON changes. This will affect beacons as well.

This is often because ssb_pcicore_init_hostmode lacks a __devinit annotation or the annotation of register_pci_controller is wrong.
