2010-04-08mac80211: enhance tracingJohannes Berg
Enhance tracing by adding tracing for a variety of callbacks that the drivers call, and also for internal calls (currently limited to queue status). This can aid debugging what is going on in mac80211 in interaction with drivers, since we can now see what drivers call and not just what mac80211 calls in the driver.

2010-04-08rt2x00: use rt2800_config_channel_rt3x for rt2872Helmut Schaa
rt2872 needs the same rf register setup as rt3070 and rt3090, hence use rt2800_config_channel_rt3x instead of rt2800_config_channel_rt2x. This change allows me to actually switch channels and hence scan all configured channels on the RT305x SoC platform (which uses a rt2872) here.

2010-04-08ath9k: simplify AR9220 fixup code for AR_AN_TOP2 registerPavel Roskin
Don't modify ah->iniModes, it's supposed to be constant. Instead, apply the fixup when the data is written to the registers. Change ath9k_hw_init_eeprom_fix() to only determine whether the fixup is needed. This allows similteneous support for AR9220 cards that need AR_AN_TOP2 fixup (such as Ubiquiti SR71-12) and those that don't need it (D-Link DWA-552 rev A2).

WEP crypto was broken, but upon finding the problem it is evident that other things were broken by the paged RX patch as well. To fix it, for now move the linearising in front.

2010-04-07mac80211: clean up/fix aggregation codeJohannes Berg
The aggregation code has a number of quirks, like inventing an unneeded WLAN_BACK_TIMER value and leaking memory under certain circumstances during station destruction. Fix these issues by using the regular aggregation session teardown code and blocking new aggregation sessions, all before the station is really destructed. As a side effect, this gets rid of the long code block to destroy aggregation safely. Additionally, rename tid_state_rx which can only have the values IDLE and OPERATIONAL to tid_active_rx to make it easier to understand that there is no bitwise stuff going on on the RX side -- the TX side remains because it needs to keep track of the driver and peer states.

2010-04-07mac80211: fix station destruction problemJohannes Berg
When a station w/o a key is destroyed, or when a driver submits work for a station and thereby references it again, it seems like potentially we could reference the station structure while it is being destroyed. Wait for an RCU grace period to elapse before finishing destroying the station after we have removed the station from the driver and from the hash table etc., even in the case where no key is associated with the station. Also, there's no point in deleting the plink timer here since it'll be properly deleted just a bit later. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

2010-04-07cfg80211: Add local-state-change-only auth/deauth/disassocJouni Malinen
cfg80211 is quite strict on allowing authentication and association commands only in certain states. In order to meet these requirements, user space applications may need to clear authentication or association state in some cases. Currently, this can be done with deauth/disassoc command, but that ends up sending out Deauthentication or Disassociation frame unnecessarily. Add a new nl80211 attribute to allow this sending of the frame be skipped, but with all other deauth/disassoc operations being completed. Similar state change is also needed for IEEE 802.11r FT protocol in the FT-over-DS case which does not use Authentication frame exchange in a transition to another BSS. For this to work with cfg80211, an authentication entry needs to be created for the target BSS without sending out an Authentication frame. The nl80211 authentication command can be used for this purpose, too, with the new attribute to indicate that the command is only for changing local state. This enables wpa_supplicant to complete FT-over-DS transition successfully. Signed-off-by: Jouni Malinen <j@w1.fi> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2010-04-07ath5k: Adaptive Noise Immunity (ANI) ImplementationBruno Randolf
This is an Adaptive Noise Imunity (ANI) implementation for ath5k. I have looked at both ath9k and HAL sources (they are nearly the same), and even though i have implemented some things differently, the basic algorithm is practically the same, for now. I hope that this can serve as a clean start to improve the algorithm later. This also adds a possibility to manually control ANI settings, right now only thru a debugfs file: * set lowest sensitivity (=highest noise immunity): echo sens-low > /sys/kernel/debug/ath5k/phy0/ani * set highest sensitivity (=lowest noise immunity): echo sens-high > /sys/kernel/debug/ath5k/phy0/ani * automatically control immunity (default): echo ani-on > /sys/kernel/debug/ath5k/phy0/ani * to see the parameters in use and watch them change: cat /sys/kernel/debug/ath5k/phy0/ani Manually setting sensitivity will turn the automatic control off. You can also control each of the five immunity parameters (noise immunity, spur immunity, firstep, ofdm weak signal detection, cck weak signal detection) manually thru the debugfs file. This is tested on AR5414 and nearly doubles the thruput in a noisy 2GHz band. Signed-off-by: Bruno Randolf <br1@einfach.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2010-04-06ath9k: remove ah->mask_reg, it's never used properlyPavel Roskin
ah->mask_reg was used to hold different data throughout the driver. ath9k_hw_init_interrupt_masks() used it to save the value written to AR_IMR. ath9k_hw_set_interrupts() used it to hold the interrupt mask as defined in enum ath9k_int. Those masks differ in many bits. Use ah->imask instead of ah->mask_reg in ath9k_hw_set_interrupts() and ath9k_hw_updatetxtriglevel(). That's what the code was meant to do. ah->imask is initialized in ath9k_start(), so we don't need to initialize it from ah->mask_reg. Once it's done, ah->mask_reg becomes write-only, so it's replaced with a local variable in ath9k_hw_init_interrupt_masks().
