2010-01-19ath9k: make tx power config changes take effect immediatleyLuis R. Rodriguez
Users wishing to tweak tx power want it to happen immediately, try to respect that. This was tested by Lorenzo by measuring the received signal strength from an AP with ath9k and the patch. Changing the tx power on the AP produced these results: 1) iwconfig wlan0 txpower 20 ---> Rx power -37dbm 2) iwconfig wlan0 txpower 15 ---> Rx power -41dbm 3) iwconfig wlan0 txpower 10 ---> Rx power -45dbm 4) iwconfig wlan0 txpower 5 ---> Rx power -51dbm 5) iwconfig wlan0 txpower 0 ---> Rx power -37dbm The result with 0 is an anomoly and would need to be addressed through a separate patch.

2010-01-19nl80211: Allow association to change channels during reassociationJouni Malinen
nl80211_associate() was rejecting (re)association attempts with EBUSY in some cases where we are currently associated with an AP that uses different channel from the destination AP. Fix this by passing the current wdev to rdev_fixed_channel() in the same way that was already done for join-IBSS and connect commands. This allows the fixedchan check to skipped for the current wdev and allows the reassociation to proceed. Signed-off-by: Jouni Malinen <j@w1.fi> Signed-off-by: John W.

2010-01-19libertas: Set/clear WPA keys before the WEP onesSamuel Ortiz
With the v10 firmware running on 8688 HW, clearing WPA keys after setting the WEP key prevents us from being able to associate with WEP APs. Swapping the calling order for assoc_helper_wpa_keys() and assoc_helper_wep_keys fixes that issue. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com> Signed-off-by: John W.

2010-01-19p54pci: move tx cleanup into taskletChristian Lamparter
This patch moves the tx cleanup routines out of the critical interrupt context and into the (previously known as rx) tasklet. The main goal of this operation is to remove the extensive usage of spin_lock_irqsaves in the generic p54common library. The next step would be to modify p54usb to do the rx processing inside a tasklet (just like usbnet). Signed-off-by: Christian Lamparter <chunkeey@googlemail.com> Signed-off-by: John W.

2010-01-19ath9k: fix RTS/CTS handlingFelix Fietkau
The Tx DMA descriptor has two kinds of flags that select RTS/CTS usage. The first one (global for the frame) selects whether RTS/CTS or CTS-to-self should be used, the second one enables RTS/CTS or CTS-to-self usage for an individual multi-rate-retry entry. Previously the code preparing the descriptor only enabled the global flag, if the first MRR series selected the local one. Fix this by enabling the global flag if any of the MRR entries need it. With this patch, rate control can properly select the use of RTS/CTS for all MRR entries except the first one, which is the default behavior.

2010-01-19mac80211: re-enable re-transmission of filtered framesJohannes Berg
In an earlier commit, mac80211: disable software retry for now Pavel Roskin reported a problem that seems to be due to software retry of already transmitted frames. It turns out that we've never done that correctly, but due to some recent changes it now crashes in the TX code. I've added a comment in the patch that explains the problem better and also points to possible solutions -- which I can't implement right now. I disabled software retry of failed/filtered frames because it was broken. With the work of the previous patches, it now becomes fairly easy to re-enable it by adding a flag indicating that the frame shouldn't be modified, but still running it through the transmit handlers to populate the control information.

2010-01-19mac80211: move control.hw_key assignmentJohannes Berg
When mac80211 asks a driver to encrypt a frame, it must assign the control.hw_key pointer for it to know which key to use etc. Currently, mac80211 does this whenever it would software-encrypt a frame. Change the logic of this code to assign the hw_key pointer when selecting the key, and later check it when deciding whether to encrypt the frame or let it be encrypted by the hardware. This allows us to later simply skip the encryption function since it no longer modifies the TX control. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

2010-01-19mac80211: remove useless setting of IEEE80211_TX_INTFL_DONT_ENCRYPTJohannes Berg
There's no value in setting a flag that will never be checked after this point, this seems to be legacy code -- I think previously the flag was used to check whether to encrypt the frame or not. Now, however, the flag need not be set, and setting it actually interferes if the frame will be processed again later. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

2010-01-18p54pci: rx frame length checkChristian Lamparter
A long time ago, a user reported several crashes due to data corruptions which are likely the result of a not-100%-supported, or faulty? PCI bridge. ( http://patchwork.kernel.org/patch/53004/ ) This patch fixes entry #1. "1. p54p_check_rx_ring - skb_over_panic: Under a ping flood or just left running for a bit would panic with a skb_over_panic." As described in the mail: The invalid frame length causes skb_put to bailout and trigger a crash. Note: Simply dropping the frame is problematic, because if its content contains a tx feedback we would lose some portion of the device memory space.... And the driver/mac80211 should handle all other invalid data. Reported-by: Quintin Pitts <geek4linux@gmail.com> Signed-off-by: Christian Lamparter <chunkeey@googlemail.com> Signed-off-by: John W.

2010-01-18mac80211: fix sign error in pid controllerBob Copeland
While testing the pid rate controller in mac80211_hwsim, I noticed that once the controller reached 54 Mbit rates, it would fail to lower the rate when necessary. The debug log shows: 1945 186786 pf_sample 50 3534 3577 50 My interpretation is that the fixed point scaling of the target error value (pf) is incorrect: the error value of 50 compared to a target of 14 case should result in a scaling value of (14-50) = -36 * 256 or -9216, but instead it is (14 * 256)-50, or 3534. Correct this by doing fixed point scaling after subtraction.
