2010-03-10ath5k: add antenna statistics and debugfs file for antenna settingsBruno Randolf
keep statistics about which antenna was used for TX and RX. this is used only for debugging right now, but might have other applications later. add a new file 'antenna' in debugfs (/sys/kernel/debug/ath5k/phy0/antenna) to show antenna use statistics and antenna diversity related register values. it can also be used to set the antenna mode until we have proper support for that in iw: - echo diversity > antenna: use default antenna mode (RX and TX diversity) - echo fixed-a > antenna: use fixed antenna A for RX and TX - echo fixed-b > antenna: use fixed antenna B for RX and TX - echo clear > antenna: reset antenna statistics Signed-off-by: Bruno Randolf <br1@einfach.org> Acked-by: Nick Kossifidis <mickflemm@gmail.com> Signed-off-by: John W.

Add support for cfg80211 set_pmksa/del_pmksa/flush_pmksa.

2010-03-10rndis_wlan: copy only useful data from rndis_command respondJussi Kivilinna
rndis_query_oid() uses full output buffer size to copy response buffer from rndis_command()/device. This doesn't cause problems as response buffer is sized based on output buffer but does copy extra unset bytes. So change rndis_query_oid() so that only meaningful bytes are being copied. Also in case of malfunctioning device/cable/etc returned data offset from device might be wrong so bound check memory access correctly, so add checks for this. v2: fixed to use new netdev_dbg/warn/etc instead of old devdbg/warn/etc Signed-off-by: Jussi Kivilinna <jussi.kivilinna@mbnet.fi> Signed-off-by: John W.

2010-03-10ath5k: Fix TX/RX padding for all framesBenoit Papillault
Currently, the padding position is based on ieee80211_get_hdrlen_from_skb(). This is not correct since the HW does padding on RX (and expect the same padding to be present on TX) at the following position : - management : 24 + 6 if 4-addr format - control : 24 + 6 if 4-addr format - data : 24 + 6 if 4-addr format + 2 if QoS - invalid : 24 + 6 if 4-addr format whereas ieee80211_get_hdrlen_from_skb() is : - management : 24 - control : 16 except for ACK/CTS where it is 10 - data : 24 + 6 if 4-addr format + 2 if QoS + 2 if QoS & order - invalid : 24 So, correct frames are not affected : management frames do not use 4-addr format, control frames have no body and invalid frames are ... not valid by definition. However, in order to use monitor interface for debugging purpose, one must be able to send/receive any frames, be it correct or not. Such frames are affected by incorrect padding. Moreover, since padding is added on TX, we need to remove it before calling ieee80211_tx_status. This affect TX packets received by monitor interfaces. It has been tested between an ath5k based card (AR5212) and an ar9170usb based card (netgear WNDA3100) using a frame generator and a monitor interface for each card. v2: Added ath5k_add_padding / ath5k_remove_padding Signed-off-by: Benoit Papillault <benoit.papillault@free.fr> Signed-off-by: John W.

2010-03-10iwmc3200wifi: refuse to associate on unallowed channelsZhu Yi
We need to make sure we don't associate with APs on unallowed channels (according to regulatory setting). This could happen when the channel is not specified (auto-select) within the connection request. In this case we get the AP's channel until the firmware indicates the association succeeded later. We need to verify the associated channel. If the channel is disabled by regulatory, we have to disassociate with the AP. Signed-off-by: Zhu Yi <yi.zhu@intel.com> Signed-off-by: John W.

2010-03-09iwlwifi: clean up queue/fifo handlingJohannes Berg
4965 hardware has 7 queues reserved and the remaining ones used for aggregation, 5000 and higher need to have 10 reserved. This is not very clear in the code right now, unfortunately. Introduce a new IWL_TX_FIFO_UNUSED constant and make the queue/FIFO mapping arrays able to hold that value, and change the setup code to reserve all queues in the arrays (the queue number is the index) and use the new unused constant to not map those queues to any FIFO. Additionally, clear up the AC/queue mapping code to be more understandable. The mapping is the identity mapping right now, but with the mapping function I think it's easier to understand what happens there. Finally, HCCA isn't implemented at all and I think newer microcode removed it, so let's remove all mention of it in the code, some comments remain for 4965.

For later station notification support we would like WEP key setting to be done synchronously always.

2010-03-09iwlwifi: remove STATUS_MODE_PENDINGJohannes Berg

With some of the new code in mac80211, public action frames can be exchanged as non-injected frames even while not associated.
