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. This means that we linearise all frames, which is not at all what we want, but at least it fixes the problem for now.

A few places in mac80211 do not currently acquire the sta lock for RX aggregation, but they should. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>

Johannes Berg authored
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.

All callers of ieee80211_sta_stop_rx_ba_session can just call __ieee80211_stop_rx_ba_session instead because they already have the station struct, so do that and remove ieee80211_sta_stop_rx_ba_session.

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.

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>

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>

The firmware does not like the host configuring the keep-alive after it has been once configured after a join-operation. Instead, it will complain about invalid parameters, which do not break functionality, but do not look nice in the syslog either. This patch prevents the complaints by only configuring the keep-alive once for an association, after the first time join is performed with the correct bssid.

The command header was missing in the wl1271_cmd_disconnect structure. It was working fine by sheer luck, because the parameters are not critical and because our wl1271_cmd_send() function was overwriting the rx_config_options with the actual header.

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().
