| | | | | | | | | | | | | | | | | | These files are non modular, but need to export symbols using the macros now living in export.h -- call out the include so that things won't break when we remove the implicit presence of module.h from everywhere.

* | mac80211: Support ht-cap over-rides.Ben Greear2011-11-211-1/+82
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This implements ht-cap over-rides for mac80211 drivers. HT may be disabled, making an /a/b/g/n station act like an a/b/g station. HT40 may be disabled forcing the station to be HT20 even if the AP and local hardware support HT40. MAX-AMSDU may be disabled. AMPDU-Density may be increased. AMPDU-Factor may be decreased. This has been successfully tested with ath9k using patched wpa_supplicant and iw. Signed-off-by: Ben Greear <greearb@candelatech.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* mac80211: optimise station flagsJohannes Berg2011-09-301-1/+1
| | | | | | | | | | | | | | | | | | | | The flaglock in struct sta_info has long been something that I wanted to get rid of, this finally does the conversion to atomic bitops. 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 deviceShahar Levi2011-06-071-0/+6
| | | | | | | | | | | | | | | | 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 annotationsJohannes Berg2011-05-161-1/+1
| | | | | | | | | | | | | | | | | | 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 lockingJohannes Berg2011-05-161-6/+21
| | | | | | | | | | | | | | | | | | | 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.

Simply avoid sending those frames, but still tear down the internal session state, since they are not really necessary anyway as we will implicitly disassociate when sending the association to the new AP.

| | | | | | | | | | | | | | | | | When the driver or rate control requests starting or stopping an aggregation session, that currently causes a direct callback into the driver, which could potentially cause locking problems. Also, the functions need to be callable from contexts that cannot sleep, and thus will interfere with making the ampdu_action callback sleeping.

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 capabilitiesJohannes Berg2009-12-211-3/+22
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

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 supportJohannes Berg2008-10-311-22/+129
| | | | | | | | | | | | | | | | | | | | 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: convert to %pM away from print_macJohannes Berg2008-10-271-26/+16
| | | | | | | | Also remove a few stray DECLARE_MAC_BUF that were no longer used at all. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: David S. Miller <davem@davemloft.net>
* mac80211: share STA information with driverJohannes Berg2008-09-151-11/+11
| | | | | | | | | | | 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.
