The corresponding iwl_mac_remove_interface only acquires the mutex, leading me to believe that the spinlock is not necessary. However, this doesn't actually acquire the mutex around the vif pointer check and assignment, fix that. Signed-off-by:

In hostap AP mode, every time the client sends the AP a packet the STA_NOTIFY_AWAKE code is sent from mac80211. This results in a command being sent to the uCode even if the client was not asleep. The following simple patch has fixed the issue for me without any degradation that I can find. Signed-off-by:

The current PS3 gelic wireless driver has support for wireless extensions. The original PS3 gelic wireless driver exposed a dedicated API for a dedicated wpa_supplicant driver. This old API could be enabled with CONFIG_GELIC_WIRELESS_OLD_PSK_INTERFACE, however, as this is not being used by any distros, and it is being removed from the driver and from wpa_supplicant.

Because DTIM information is required for powersave but is only conveyed in beacons, wait for a beacon before enabling powersave, and change the way the information is conveyed to the driver accordingly. mwl8k doesn't currently seem to implement PS but requires the DTIM period in a different way; after talking to Lennert we agreed to just have mwl8k do the parsing itself in the finalize_join work.

Currently, the remain_on_channel work callback needs to track in its own data structure whether the work was just started or not. By reordering some code this becomes unnecessary, the generic wk->started variable can still be 'false' on the first invocation and only be 'true' on actual timeout invocations, so that the extra variable can be removed.

What a stupid mistake. In commit 813d7669 Author: Johannes Berg <johannes@sipsolutions.net> Date: Sun Jan 17 01:47:58 2010 +0100 mac80211: move control.hw_key assignment I inserted code testing the wrong flags field, which means that the test is almost always true (it's really testing for the peer's WMM support) and thus the later parts of the stack assume hw crypto will be done even if that's not true. Obviously, that broke software crypto. Maxim said so specifically, and Jochen probably uses some cipher that iwl3945 doesn't support in hardware, which might also explain that Maxim reports that even hw crypto is broken. Fix this to test the right flags field. Reported-by:Maxim Levitsky <maximlevitsky@gmail.com> Reported-by:

ieee80211_work_rx_mgmt currently enqueues various management frames, including deauth and disassoc frames, however the function ieee80211_work_rx_queued_mgmt does not handle these, as they should only occur if the AP is buggy. It does emit a WARN_ON when this happens though, and several users have reported such instances. Fix the WARN_ON by not queueing such frames in the first place. Signed-off-by:

The TKIP key update callback is called from the RX path, where the driver mutex is already locked. This results in a circular locking bug. Avoid this by removing the lock. Johannes noted that there is a separate bug: The callback still breaks on SDIO hardware, because SDIO hardware access needs to sleep, but we are not allowed to sleep in the callback due to mac80211's RCU locking.

ath9k currently forces hw->max_rate_tries to 4 to work around rate control inefficiencies. This has some negative side effects, such as rate_control_send_low also using a maximum of 4 tries, which could negatively affect reliability of unicast management frames. This patch pushes the retry limit to the rate control instead, and allows it to use more tries on the last stage to prevent unnecessary packet loss. Signed-off-by:

The following commit commit e4da8c37 Author: Johannes Berg <johannes@sipsolutions.net> Date: Wed Dec 23 13:15:43 2009 +0100 mac80211: make off-channel work generic triggered a bug in iwlwifi where HT parameters would not be correctly set in some mac80211 pathways. The aggregation (and possibly other) station flags were not being set, which limited the size of aggregation blocks and reduced throughput at high rates. >From Johannes: """ Due to Wey-Yi's patch to use the set-channel command when the channel changes while associated, we don't get a full new RXON. Therefore, we don't re-set the rxon-station either. However, under some circumstances that apparently have gotten more likely mac80211 will first set up the BSS info, then add the station and then switch to an HT channel type. Therefore, the check for "priv->current_ht_config.is_ht" in iwl_rxon_add_station() will hit false and not fill in the HT information. However, that check can just be removed, which is the easiest fix for all this, because the HT capa struct is always there, just could possibly have the ht_supported member set to false.

In iwlagn the support for spectrum measurement command has been disabled since v2.6.29 without any requests for it. In addition to this when this command is indeed enabled it has been found to trigger firmware SYSASSERT on at least 4965 and 5100 hardware (see http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=1952 ). Since then this code has been bitrotting and cannot just be enabled without porting. Remove support for spectrum measurement command from iwlagn. It can be added back if there is a future need and the firmware problem it triggers has been fixed. Support for the spectrim measurement notification remains as it has been enabled all the time. In addition to this remove the 3945 spectrum measurement command Kconfig option and make this command always supported. The code added by this enabling is minimal and only run when user triggers a spectrum measurement request via sysfs. Signed-off-by:

It is better to first notify cfg80211 about the hw rfkill state (so the rfkill device that will be registered won't have the wrong state while being registered), and the power/tt variable init can (and probably should) also be done first. Also rename iwl_setup_mac to iwl_mac_setup_register to better describe what it really does. Signed-off-by:

Adding "bt_coex_active" module parameter for iwlcore to enable/disable BT coexist; if bt_coex_active is true (default), uCode will do kill/defer every time the priority line is asserted (BT is sending signals on the priority line in the PCIx). By disable the bt_coex_active, uCode will ignore the BT activity and perform the normal operation. Users might experience transmit issue on some platform due to this WiFi/BT co-exist problem. The possible symptoms are: NetworkManager and other similar programs can scan and find all the available APs, but will timeout and unable to associate with any of the APs; no out-going frames can be found with wireless sniffer tools. On those platforms, WiFi communication can be restored by set "bt_coex_active" module parameter to "false" Signed-off-by:

Add function pointer for broadcast station addition so that we can call it in from iwlcore at a later time. We only distinguish between iwlagn and iwl3945 broadcast station addition. For the iwl3945 station addition we add that function to iwlcore since that is where most station functionality resides, making it part of iwl3945 will require significant code reorganization that will dilute station management functionality. This seems to be an efficient solution. It may seem as though we are removing error checking when adding the 3945 broadcast station but this error checking was never really necessary since the function returns the station id and the broadcast station id is always set.

The work done when a station is added is very similar whether the station is added synchronously or asynchronously. Centralize this work. At the same time increase the status flags being checked for when the command returns with accompanying debug messages. Also increase checking when setting the "ucode active" state with accompanying debugging. This work is done in preparation for station notification support. Signed-off-by:

We have seen the throughput dropped due to external noisy environment and the radio is out of tune. There are lot of plcp errors indicating this condition. Eventually the station can get de-authenticated by the Access Point. By resetting and tuning the radio, the plcp errors are reduced or eliminated and the throughput starts to rise. To prevent unexpected behavior such as drop in throughput or deauthentication, - The change provides the driver feature to monitor and tune the radio base on the statistics notification from the uCode. - It also allows the setting of the plcp error rate threshold via the plcp_delta under debugfs interface.
