* at76c50x-usb: remove unneeded flush_workqueue() at usb disconnectLuis R. Rodriguez2009-08-041-3/+1
| | | | | | | | | | | This driver only uses the mac80211 workqueue and mac80211 requires us to cancel all work at driver stop. Since we now have the cancels in the right places at stop() we really don't need to flush the mac80211 workqueue so remove it. Signed-off-by: Luis R.

* ath5k: fix CAB queue operationBob Copeland2009-08-041-1/+4
| | | | | | | | | We need to process tx descriptors for all queues (currently main tx queue and cabq) which may have triggered the TX completion interrupt. Otherwise, the queues can get stuck after sending a few frames. Signed-off-by: Bob Copeland <me@bobcopeland.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* b43: Work around mac80211 race conditionLarry Finger2009-08-041-6/+15
| | | | | | | | | | | | | | | | | | | As shown in http://thread.gmane.org/gmane.linux.kernel.wireless.general/36497, mac80211 has a bug that allows a call to the TX routine after the queues have been stopped. This situation will only occur under extreme stress. Although b43 does not crash when this condition occurs, it does generate a WARN_ON and also logs a queue overrun message. This patch recognizes b43 is not at fault and logs a message only when the most verbose debugging mode is enabled. In the unlikely event that the queue is not stopped when the DMA queue becomes full, then a warning is issued. During testing of this patch with one output stream running repeated tcpperf writes and a second running a flood ping, this routine was entered with the DMA ring stopped about once per hour. The condition where the DMA queue is full but the ring has not been stopped has never been seen by me. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: John W.

* ath5k: update PCU opmode whenever a new interface is addedBob Copeland2009-08-041-0/+3
| | | | | | | | | | | | | | | Previously, we would store the operating mode at interface up time, but only update the PCU registers when the next reset happened. The result is that if beacon configuration (ops->bss_info_changed) happens before ops->config, we will program the wrong things into the timer registers. Consequently, beacons won't work in AP mode until after a reset (channel change, scan etc.). This is fragile anyway so just program the opmode as soon as mac80211 gives it to us.

* ath9k: Update rate control for 11NA HT40 modeVasanthakumar Thiagarajan2009-08-041-3/+1
| | | | | | | | | | | Now the lowest rate in 11na ht40 mode is 13.5Mbps this shortens the range when compared to 11na ht20 mode where the lowest rate is 6.5Mbps. To improve the range, make 6.5Mbps as the lowest rate in 11na ht40 mode, this improves the range by approximately 2dB. 11ng ht40 does not have this issue as it also has basic rates (1, 2, 5.5 and 11).

* cfg80211: keep track of current_bss for userspace SMEJohannes Berg2009-08-044-33/+51
| | | | | | | | | | | | | When a userspace SME is active, we're currently not keeping track of the BSS properly for reporting the current link and for internal use. Additionally, it looks like there is a possible BSS leak in that the BSS never gets removed from auth_bsses[]. To fix it, pass the BSS struct to __cfg80211_connect_result in this case.

* mac80211: disable beacons before removing the associated interfaceBob Copeland2009-08-043-1/+16
| | | | | | | | | | | | | | When downing interfaces, it's a good idea to tell the driver to stop sending beacons; that way the driver doesn't need special code in ops->remove_interface() when it should already handle the case in bss_info_changed(). This fixes a potential crash with at least ath5k since the vif pointer will be nullified while beacon interrupts are still active.

* rt2x00: Fix build error when crypto support is disabledIvo van Doorn2009-08-041-10/+10
| | | | | | | | | | | | | | | When only rt2400pci or rt2500pci is compiled without any of the other rt2x00 modules, then CONFIG_RT2X00_LIB_CRYPTO will not be enabled. However rt2x00mac_set_tim() implemented within #ifdef CONFIG_RT2X00_LIB_CRYPTO statements while the declaration is placed outside the definition. This results in linking errors as reporte by Ken. rt2x00_set_tim() has nothing to do with crypto, and thus should be moved outside of the #ifdef statements.

* neigh: Convert garbage collection from softirq to workqueueEric Dumazet2009-08-022-48/+45
| | | | | | | | | | | | | | | | | | Current neigh_periodic_timer() function is fired by timer IRQ, and scans one hash bucket each round (very litle work in fact) As we are supposed to scan whole hash table in 15 seconds, this means neigh_periodic_timer() can be fired very often. (depending on the number of concurrent hash entries we stored in this table) Converting this to a workqueue permits scanning whole table, minimizing icache pollution, and firing this work every 15 seconds, independantly of hash table size. This 15 seconds delay is not a hard number, as work is a deferrable one. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
