2010-06-24ath9k: Fix bug in paprdVasanthakumar Thiagarajan
It is possbile that the transmission of paprd test frame might not get completed in 100ms if tx is stuck. Freeing this skb upon timeout in ath_paprd_calibrate() will result in accessing already freed memory when the associated pending buffer is drained in txq. This patch fixes this issue.

2010-06-24rt2500usb: fallback to SW encryption for TKIP+AESOndrej Zary
HW crypto in rt2500usb does not seem to support keys with different ciphers, which breaks TKIP+AES mode. Fall back to software encryption to fix it. This should fix long-standing problems with rt2500usb and WPA, such as: http://rt2x00.serialmonkey.com/phpBB/viewtopic.php?f=4&t=4834 https://bugzilla.redhat.com/show_bug.cgi?id=484888 Also tested that it does not break WEP, TKIP-only and AES-only modes.

2010-06-24nl80211: Add option to adjust transmit powerJuuso Oikarinen
This patch adds transmit power setting type and transmit power level attributes to NL80211_CMD_SET_WIPHY in order to facilitate adjusting of the transmit power level of the device. The added attributes allow selection of automatic, limited or fixed transmit power level, with the level definable in signed mBm format.

2010-06-24cfg80211/mac80211: Update set_tx_power to use mBm instead of dBm unitsJuuso Oikarinen
In preparation for a TX power setting interface in the nl80211, change the .set_tx_power function to use mBm units instead of dBm for greater accuracy and smaller power levels. Also, already in advance move the tx_power_setting enumeration to nl80211. This change affects the .tx_set_power function prototype. As a result, the corresponding changes are needed to modules using it. These are mac80211, iwmc3200wifi and rndis_wlan.

2010-06-24at76c50x-usb: Extract bssid from authentication frameSebastian Smolorz
The driver at76c50x-usb is unable to authenticate with an AP since kernel 2.6.31 for the following reason: The join command of the firmware needs to be sent with the right bssid before any transmission can start. Before kernel 2.6.31 mac80211 informed its drivers about the changing bssid early enough for at76c50x-usb but during the development of 2.6.31 mac80211's behaviour changed. Now a new bssid is set after the association. This patch changes the tx routine of the driver at76c50x-usb in such a way that a new bssid is extracted from an authentication frame and the join command with that bssid is processed.

2010-06-24at76c50x-usb: Move function at76_join() several lines upSebastian Smolorz
This patch does a simple code move of at76_join() so that at76_mac80211_tx() follows at76_join() in the driver's source file. This is a preparatory patch for the following patch where we need to call at76_join() from at76_mac80211_tx() in order to authenticate successfully with a bssid.

2010-06-24mac80211: avoid scheduling while atomic in mesh_rx_plink_frameJohn W. Linville
While mesh_rx_plink_frame holds sta->lock... mesh_rx_plink_frame -> mesh_plink_inc_estab_count -> ieee80211_bss_info_change_notify ...but ieee80211_bss_info_change_notify is allowed to sleep. A driver taking advantage of that allowance can cause a scheduling while atomic bug. Similar paths exist for mesh_plink_dec_estab_count, so work around those as well. http://bugzilla.kernel.org/show_bug.cgi?id=16099 Also, correct a minor kerneldoc comment error (mismatched function names).

2010-06-21mac80211: Add interface for driver to temporarily disable dynamic psmaster-2010-06-21Juuso Oikarinen
This mechanism introduced in this patch applies (at least) for hardware designs using a single shared antenna for both WLAN and BT. In these designs, the antenna must be toggled between WLAN and BT. In those hardware, managing WLAN co-existence with Bluetooth requires WLAN full power save whenever there is Bluetooth activity in order for WLAN to be able to periodically relinquish the antenna to be used for BT. This is because BT can only access the shared antenna when WLAN is idle or asleep. Some hardware, for instance the wl1271, are able to indicate to the host whenever there is BT traffic. In essence, the hardware will send an indication to the host whenever there is, for example, SCO traffic or A2DP traffic, and will send another indication when the traffic is over. The hardware gets information of Bluetooth traffic via hardware co-existence control lines - these lines are used to negotiate the shared antenna ownership. The hardware will give the antenna to BT whenever WLAN is sleeping. This patch adds the interface to mac80211 to facilitate temporarily disabling of dynamic power save as per request of the WLAN driver. This interface will immediately force WLAN to full powersave, hence allowing BT coexistence as described above. In these kind of shared antenna desings, when WLAN powersave is fully disabled, Bluetooth will not work simultaneously with WLAN at all. This patch does not address that problem. This interface will not change PSM state, so if PSM is disabled it will remain so. Solving this problem requires knowledge about BT state, and is best done in user-space.

2010-06-18mac80211: fix sw scan bracketingmaster-2010-06-18Johannes Berg
Currently, detection in hwsim and ath9k can detect that two sw scans are in flight at the same time, which isn't really true. It is caused by a race condition, because the scan complete callback is called too late, after the lock has been dropped, so that a new scan can be started before it is called. It is also called too early semantically, as it is currently called _after_ the return to the operating channel -- it should be before so that drivers know this is the operating channel again.
