2010-03-11minstrel: simplify and fix debugfs codeFelix Fietkau2-29/+11
This patch cleans up the debugfs read function for the statistics by using simple_read_from_buffer instead of its own semi-broken hack. Also removes a useless member of the minstrel debugfs info struct. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-03-11ath5k: Fix TX/RX padding for all framesBenoit Papillault3-36/+88
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.

2010-03-11mac80211: give warning if building w/out rate ctrl algorithmAndres Salomon1-0/+9
I discovered that if EMBEDDED=y, one can accidentally build a mac80211 stack and drivers w/ no rate control algorithm. For drivers like RTL8187 that don't supply their own RC algorithms, this will cause ieee80211_register_hw to fail (making the driver unusable). This will tell kconfig to provide a warning if no rate control algorithms have been selected. That'll at least warn the user; users that know that their drivers supply a rate control algorithm can safely ignore the warning, and those who don't know (or who expect to be using multiple drivers) can select a default RC algorithm.

2010-03-11iwmc3200wifi: refuse to associate on unallowed channelsZhu Yi3-3/+25
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.

2010-03-10iwlwifi: clean up queue/fifo handlingJohannes Berg5-77/+109
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.

These files are incompatible with some changes I'm making, and don't really belong into sysfs anyway as they can only be used for debugging.

2010-03-10iwlwifi: remove STATUS_MODE_PENDINGJohannes Berg5-44/+19
Since rfkill integration, mac80211 can no longer add an interface while the hardware is not ready, so STATUS_MODE_PENDING can never be set.

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

Drivers can now advertise to cfg80211 that they have multiple MAC addresses reserved for a device, but we don't currently make use of that in mac80211.

2010-03-09mac80211: Improve software scan timingHelmut Schaa2-6/+66
The current software scan implemenation in mac80211 returns to the operating channel after each scanned channel. However, in some situations (e.g. no traffic) it would be nicer to scan a few channels in a row to speed up the scan itself. Hence, after scanning a channel, check if we have queued up any tx frames and return to the operating channel in that case. Unfortunately we don't know if the AP has buffered any frames for us. Hence, scan only as many channels in a row as the pm_qos latency and the negotiated listen interval allows us to. Signed-off-by: Helmut Schaa <helmut.schaa@googlemail.com> Signed-off-by: John W.
