mac80211: send {ADD,DEL}BA on AC_VO like other mgmt frames, as per spec ATM, {ADD,DEL}BA and BAR frames are sent on the AC matching the TID of the BA parameters. In the discussion [1] about this patch, Johannes recalled that it fixed some races with the DELBA and indeed this behavior was introduced in [2]. While [2] is right for the BARs, the part queueing the {ADD,DEL}BAs on their BA params TID AC violates the spec and is more a workaround for some drivers. Helmut expressed some concerns wrt such drivers, in particular DELBAs in rt2x00. ATM, DELBAs are sent after a driver has called (hence "purposely") ieee80211_start_tx_ba_cb_irqsafe and Johannes and Emmanuel gave some details wrt intentions behind the split of the IEEE80211_AMPDU_TX_STOP_* given to the driver ampdu_action supposed to call this function, which could prove handy to people trying to do the right thing in faulty drivers (if their fw/hw don't get in their way).

mac80211: implement SMPS for AP When the driver requests to move to STATIC or DYNAMIC SMPS, we send an action frame to each associated station and reconfigure the channel context / driver. Of course, non-MIMO stations are ignored. The beacon isn't updated. The association response will include the original capabilities. Stations that associate while in non-OFF SMPS mode will get an action frame right after association to inform them about our current state. Note that we wait until the end of the EAPOL. Sending an action frame before the EAPOL is finished can be an issue for a few clients. Clients aren't likely to send EAPOL frames in MIMO anyway. When the SMPS configuration gets more permissive (e.g. STATIC -> OFF), we don't wake up stations that are asleep We remember that they don't know about the change and send the action frame when they wake up. When the SMPS configuration gets more restrictive (e.g. OFF -> STATIC), we set the TIM bit for every sleeping STA. uAPSD stations might send MIMO until they poll the action frame, but this is for a short period of time.

mac80211: fix HT capability overrides for AP station HT capabilites are asymmetric -- e.g. beamforming is both an RX and TX capability. If, for example, we support RX but not TX, the RX capability of the AP station is masked out (if it supports it). This works correctly if it's really the driver capability. If, on the other hand, the reason for not supporting TX BF is that it was removed by HT capability overrides then the wrong thing happens: the AP's TX capability will be removed rather than its RX capability, because the override function works on own capabilities, not remote ones, and doesn't take the asymmetry into account. To fix this make a copy of our own capabilities, apply the overrides to them (where needed) and then use that to set up the peer's capabilities. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

mac80211: stop toggling IEEE80211_HT_CAP_SUP_WIDTH_20_40 For VHT, many more bandwidth changes are possible. As a first step, stop toggling the IEEE80211_HT_CAP_SUP_WIDTH_20_40 flag in the HT capabilities and instead introduce a bandwidth field indicating the currently usable bandwidth to transmit to the station. Of course, make all drivers use it. To achieve this, make ieee80211_ht_cap_ie_to_sta_ht_cap() get the station as an argument, rather than the new capabilities, so it can set up the new bandwidth field. If the station is a VHT station and VHT bandwidth is in use, also set the bandwidth accordingly. Doing this allows us to get rid of the supports_40mhz flag as the HT capabilities now reflect the true capability instead of the current setting. While at it, also fix ieee80211_ht_cap_ie_to_sta_ht_cap() to not ignore HT cap overrides when MCS TX isn't supported (not that it really happens...)

mac80211: set HT channel before association Changing the channel type during operation is confusing to some drivers and will be hard to handle in multi-channel scenarios. Instead of changing the channel, set it to the right HT channel before authenticating/associating and don't change it -- just update the 20/40 MHz restrictions in rate control as needed when changed by the AP. This also fixes a problem that Paul missed in his fix for the "regulatory makes us deaf" issue -- when we couldn't use 40 MHz we still associated saying we were using 40 MHz, which could in similarly broken APs make us never even connect successfully.

The conversion itself is straight-forward in most places, a few things needed to change a bit since we can no longer use multiple bits at the same time. On x86-64, this is a fairly significant code size reduction: text data bss dec hex 427861 23648 1008 452517 6e7a5 before 425383 23648 976 450007 6ddd7 after Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W.

mac80211: Stop BA session event from device Some devices support BT/WLAN co-existence algorigthms. In order not to harm the system performance and user experience, the device requests not to allow any RX BA session and tear down existing RX BA sessions based on system constraints such as periodic BT activity that needs to limit WLAN activity (eg.SCO or A2DP). In such cases, the intention is to limit the duration of the RX PPDU and therefore prevent the peer device to use A-MPDU aggregation. Adding ieee80211_stop_rx_ba_session() callback that can be used by the driver to stop existing BA sessions. Signed-off-by: Shahar Levi <shahar_levi@ti.com> Signed-off-by: John W.

mac80211: sparse RCU annotations This adds sparse RCU annotations to most of mac80211, only the mesh code remains to be done. Due the the previous patches, the annotations are pretty simple. The only thing that this actually changes is removing the RCU usage of key->sta in debugfs since this pointer isn't actually an RCU-managed pointer (it only has a single assignment done before the key even goes live). As that is otherwise harmless, I decided to make it part of this patch. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

mac80211: fix TX a-MPDU locking During my quest to make mac80211 not have any RCU warnings from sparse, I came across the a-MPDU code again and it wasn't quite clear why it isn't racy. So instead of assigning the tid_tx array with just the spinlock held in ieee80211_start_tx_ba_session use a separate temporary array protected only by the spinlock and protect all assignments to the "live" array by both the spinlock and the mutex so that other code is easily verified to be correct. Due to pointer assignment atomicity I don't think this is a real issue, but I'm not sure, especially on Alpha the current code might be problematic.

mac80211: reduce reliance on netdev For bluetooth 3, we will most likely not have a netdev for a virtual interface (sdata), so prepare for that by reducing the reliance on having a netdev. This patch moves the name and address fields into the sdata struct and uses them from there all over. Some work is needed to keep them sync'ed, but that's not a lot of work and in slow paths anyway. In doing so, this also reduces the number of pointer dereferences in many places, because of things like sdata->dev->dev_addr becoming sdata->vif.addr.

mac80211: fix peer HT capabilities I noticed yesterday, because Jeff had noticed a speed regression, cf. bug http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2138 that the SM PS settings for peers were wrong. Instead of overwriting the SM PS settings with the local bits, we need to keep the remote bits. The bug was part of the original HT code from over two years ago, but unfortunately nobody noticed that it makes no sense -- we shouldn't be overwriting the peer's setting with our own but rather keep it intact when masking the peer capabilities with our own. While fixing that, I noticed that the masking of capabilities is completely useless for most of the bits, so also fix those other bits. Finally, I also noticed that PSMP_SUPPORT no longer exists in the final 802.11n version, so also remove that. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

mac80211: fix spurious delBA handling Lennert Buytenhek noticed that delBA handling in mac80211 was broken and has remotely triggerable problems, some of which are due to some code shuffling I did that ended up changing the order in which things were done -- this was commit d75636ef9c1af224f1097941879d5a8db7cd04e5 Author: Johannes Berg <johannes@sipsolutions.net> Date: Tue Feb 10 21:25:53 2009 +0100 mac80211: RX aggregation: clean up stop session and other parts were already present in the original commit d92684e66091c0f0101819619b315b4bb8b5bcc5 Author: Ron Rindjunsky <ron.rindjunsky@intel.com> Date: Mon Jan 28 14:07:22 2008 +0200 mac80211: A-MPDU Tx add delBA from recipient support The first problem is that I moved a BUG_ON before various checks -- thereby making it possible to hit. As the comment indicates, the BUG_ON can be removed since the ampdu_action callback must already exist when the state is != IDLE. The second problem isn't easily exploitable but there's a race condition due to unconditionally setting the state to OPERATIONAL when a delBA frame is received, even when no aggregation session was ever initiated. All the drivers accept stopping the session even then, but that opens a race window where crashes could happen before the driver accepts it. Right now, a WARN_ON may happen with non-HT drivers, while the race opens only for HT drivers. For this case, there are two things necessary to fix it: 1) don't process spurious delBA frames, and be more careful about the session state; don't drop the lock 2) HT drivers need to be prepared to handle a session stop even before the session was really started -- this is true for all drivers (that support aggregation) but iwlwifi which can be fixed easily. The other HT drivers (ath9k and ar9170) are behaving properly already.

The reason to do this is to better separate the state machines, and have the code be contained better so it gets easier to determine what exactly a given change will affect, that in turn makes it easier to understand. This is quite some churn, especially because I split sdata->u.sta into sdata->u.mgd and sdata->u.ibss, but I think it's easier to maintain that way. I've also shuffled around some code -- null function sending is only applicable to managed interfaces so put that into that file, some other functions are needed from various places so put them into util, and also rearranged the prototypes in ieee80211_i.h accordingly.

mac80211: Re-enable aggregation Wireless HW without any dedicated queues for aggregation do not need the ampdu_queues mechanism present right now in mac80211. Since mac80211 is still incomplete wrt TX MQ changes, do not allow aggregation sessions for drivers that set ampdu_queues. This is only an interim hack until Intel fixes the requeue issue.

mac80211: rewrite HT handling The HT handling has the following deficiencies, which I've (partially) fixed: * it always uses the AP info even if there is no AP, hence has no chance of working as an AP * it pretends to be HW config, but really is per-BSS * channel sanity checking is left to the drivers * it generally lets the driver control too much HT enabling is still wrong with this patch if you have more than one virtual STA mode interface, but that never happens currently. Once WDS, IBSS or AP/VLAN gets HT capabilities, it will also be wrong, see the comment in ieee80211_enable_ht(). Additionally, this fixes a number of bugs: * mac80211: ieee80211_set_disassoc doesn't notify the driver any more since the refactoring * iwl-agn-rs: always uses the HT capabilities from the wrong stuff mac80211 gives it rather than the actual peer STA * ath9k: a number of bugs resulting from the broken HT API I'm not entirely happy with putting the HT capabilities into struct ieee80211_sta as restricted to our own HT TX capabilities, but I see no cleaner solution for now.

802.11: clean up/fix HT support This patch cleans up a number of things: * the unusable definition of the HT capabilities/HT information information elements * variable names that are hard to understand * mac80211: move ieee80211_handle_ht to ht.c and remove the unused enable_ht parameter * mac80211: fix bug with MCS rate 32 in ieee80211_handle_ht * mac80211: fix bug with casting the result of ieee80211_bss_get_ie to an information element _contents_ rather than the whole element, add size checking (another out-of-bounds access bug fixed!) * mac80211: remove some unused return values in favour of BUG_ON checking * a few minor other things Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

mac80211: share STA information with driver This patch changes mac80211 to share some more data about stations with drivers. Should help iwlwifi and ath9k when they get around to updating, and might also help with implementing rate control algorithms without internals.

mac80211: use nl80211 interface types There's really no reason for mac80211 to be using its own interface type defines.

mac80211: make BA session handling independent of STA mode The aggregation handling isn't dependent on anything related to our STA-mode implementation, and doesn't need to depend on it for frame processing. This patch moves the relevant code to ht.c and adds a hook in rx.c. For now, the relevant action frames are only processed in STA/IBSS modes, but that's now something we can easily change.
