* rt2x00: Move common txdone handling to rt2x00lib_txdone.Gertjan van Wingerde2010-06-308-55/+20
| | | | | | | | | | Now that the write_tx_data functions are merged, also merge the relevant parts of the txdone handling into common code, rather than {usb,pci} specific code.

| | | | | | | | | | | | The update_bssid is set only when BSS_CHANGED_BSSID is used, but the check if that field is true is done later in the function but also only when BSS_CHANGED_BSSID is set. This makes the variable useless, as it can never result in a negative check.

* rt2x00: Write the BSSID to register when interface is addedIvo van Doorn2010-06-301-1/+2
| | | | | | | | | | | | | | | | For the Master mode case, we initialized the BSSID as the MAC address, but never wrote it into the registers. This causes Hardware crypto to break in Master mode when receiving frames which require the BSSID to be filled in. This is safe for STA mode since the BSSID will be initialized to 00:00:00:00:00 at this point, but will be set to the correct value later when the device associates.

* rt2x00: Implement tx mpdu aggregationHelmut Schaa2010-06-302-1/+48
| | | | | | | | | | | | | | | | In order to implement tx mpdu aggregation we only have to implement the ampdu_action callback such that mac80211 allows negotiation of blockack sessions. The hardware will handle everything on its own as long as the ampdu flag in the TXWI struct is set up correctly and we translate the tx status correctly. For now, refuse requests to start rx aggregation. Signed-off-by: Helmut Schaa <helmut.schaa@googlemail.com> Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

* ath9k: fix retry count for A-MPDU rate control status reportsFelix Fietkau2010-06-281-3/+8
| | | | | | | | | | | | | | | | | | | | | | The 'bf_retries' field of the ath_buf structure was used for both software retries (AMPDU subframes) and hardware retries (legacy frames). This led to a wrong retry count being reported for the A-MPDU rate control stats. This patch changes the code to no longer use bf_retries for reporting retry counts, but instead always using the real on-chip retry count from the ath_tx_status. Additionally, if the first subframe of an A-MPDU was not acked, the tx status report is submitted along with the first acked subframe, which may not contain the correct rates in the tx info. This is easily corrected by saving the tx rate info before looping over subframes, and then copying it back once the A-MPDU status report is submitted. In my tests this change improves throughput visibly. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Reported-by: Björn Smedman <bjorn.smedman@venatech.se> Cc: stable@kernel.org Signed-off-by: John W.

* ath5k: fix antenna div gc for <= AR5K_SREV_PHY_2413Bruno Randolf2010-06-281-1/+1
| | | | | | | | | | | | In commit 39d5b2c83ca8904b6826a0713263a4e5a9c0730a "ath5k: update AR5K_PHY_RESTART_DIV_GC values to match masks" i introduced a regression on PHY chips older than AR5K_SREV_PHY_5413, which caused signal values to be about 10dB less that before. This patch reverts the AR5K_PHY_RESTART_DIV_GC values to the same values which were effectively used before (without the bitmask mistake). This brings signal levels back to normal on these PHY chips.

* iwlwifi: update LQ for bcast station on channel changeDaniel Halperin2010-06-258-0/+40
| | | | | | | | | | | | | | The rate table in the bcast LQ is computed only when the station is allocated, and chooses the lowest rate for the band. Because of when this occurs, this is the 2.4 GHz band and uses the 0x420a (CCK, 1 Mbps) rate. In 5 GHz beaconing mode, this rate will prevent beacons from being sent and any other packets from being received. We can fix this by re-initializing the bcast station's LQ command when the channel is changed.

RTS/CTS is is required for HT traffic in a noisy environment where, without this setting, connections will stall on some hardware as documented in the patch that initially attempted to address this: commit 1152dcc28c66a74b5b3f1a3ede0aa6729bfd48e4 Author: Wey-Yi Guy <wey-yi.w.guy@intel.com> Date: Fri Jan 15 13:42:58 2010 -0800 iwlwifi: Fix throughput stall issue in HT mode for 5000 Similar to 6000 and 1000 series, RTS/CTS is the recommended protection mechanism for 5000 series in HT mode based on the HW design.

The reason, it turns out, is that the code previously checked if ALLMULTI _changed_, which the new code no longer did, and normally it _never_ changes. Had somebody changed it manually, the code prior to my patch there would have been broken already. The reason is that we always, unconditionally, ask the device to pass up all multicast frames, but the new code made it depend on ALLMULTI which broke it since now we'd pass up multicast frames depending on the default filter in the device, which isn't necessarily what we want (since we don't program it right now). Fix this by simply not checking allmulti as we have allmulti behaviour enabled already anyway.

| * ath9k: Fix bug in starting aniVasanthakumar Thiagarajan2010-06-232-1/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are few places where ANI is started without checking if it is right to start. This might lead to a case where ani timer would be left undeleted and cause improper memory acccess during module unload. This bug is clearly exposed with paprd support where the driver detects tx hang and does a chip reset. During this reset ani is (re)started without checking if it needs to be started. This would leave a timer scheduled even after all the resources are freed and cause a panic. This patch introduces a bit in sc_flags to indicate if ani needs to be started in sw_scan_start() and ath_reset(). This would fix the following panic. This issue is easily seen with ar9003 + paprd.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | nl80211: Add option to adjust transmit powerJuuso Oikarinen2010-06-242-0/+40
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* | cfg80211/mac80211: Update set_tx_power to use mBm instead of dBm unitsJuuso Oikarinen2010-06-246-41/+51
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | at76c50x-usb: Extract bssid from authentication frameSebastian Smolorz2010-06-242-0/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | 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.

* | mac80211: avoid scheduling while atomic in mesh_rx_plink_frameJohn W. Linville2010-06-241-11/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).
