2009-03-27mac80211/iwlwifi: move virtual A-MDPU queue bookkeeping to iwlwifiJohannes Berg17-169/+84
This patch removes all the virtual A-MPDU-queue bookkeeping from mac80211. Curiously, iwlwifi already does its own bookkeeping, so it doesn't require much changes except where it needs to handle starting and stopping the queues in mac80211. To handle the queue stop/wake properly, we rewrite the software queue number for aggregation frames and internally to iwlwifi keep track of the queues that map into the same AC queue, and only talk to mac80211 about the AC queue. The implementation requires calling two new functions, iwl_stop_queue and iwl_wake_queue instead of the mac80211 counterparts.

2009-03-27mac80211: fix aggregation to not require queue stopJohannes Berg7-78/+221
Instead of stopping the entire AC queue when enabling aggregation (which was only done for hardware with aggregation queues) buffer the packets for each station, and release them to the pending skb queue once aggregation is turned on successfully. We get a little more code, but it becomes conceptually simpler and we can remove the entire virtual queue mechanism from mac80211 in a follow-up patch. This changes how mac80211 behaves towards drivers that support aggregation but have no hardware queues -- those drivers will now not be handed packets while the aggregation session is being established, but only after it has been fully established.

2009-03-27mac80211: add skb length sanity checkingJohannes Berg1-1/+6
We just found a bug in zd1211rw where it would reject packets in the ->tx() method but leave them modified, which would cause retransmit attempts with completely bogus skbs, eventually leading to a panic due to not having enough headroom in those. This patch adds a sanity check to mac80211 to catch such driver mistakes; in this case we warn and drop the skb. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2009-03-27mac80211: unify and fix TX aggregation startJohannes Berg3-39/+30
When TX aggregation becomes operational, we do a number of steps: 1) print a debug message 2) wake the virtual queue 3) notify the driver Unfortunately, 1) and 3) are only done if the driver is first to reply to the aggregation request, it is, however, possible that the remote station replies before the driver! Thus, unify the code for this and call the new function ieee80211_agg_tx_operational in both places where TX aggregation can become operational. Additionally, rename the driver notification from IEEE80211_AMPDU_TX_RESUME to IEEE80211_AMPDU_TX_OPERATIONAL. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

2009-03-27mac80211: clean up __ieee80211_tx argsJohannes Berg1-15/+16
__ieee80211_tx takes a struct ieee80211_tx_data argument, but only uses a few of its members, namely 'skb' and 'sta'. Make that explicit, so that less internal knowledge is required in ieee80211_tx_pending and the possibility of introducing errors here is removed.

2009-03-27mac80211: rework the pending packets codeJohannes Berg4-79/+98
The pending packets code is quite incomprehensible, uses memory barriers nobody really understands, etc. This patch reworks it entirely, using the queue spinlock, proper stop bits and the skb queues themselves to indicate whether packets are pending or not (rather than a separate variable like before).

2009-03-27mac80211: fix A-MPDU queue assignmentJohannes Berg1-8/+27
Internally, mac80211 requires the skb's queue mapping to be set to the AC queue, not the virtual A-MPDU queue. This is not done correctly currently, this patch moves the code down to directly before the driver is invoked and adds a comment that it will be moved into the driver later. Since this requires __ieee80211_tx() to have the sta pointer, make sure to provide it in ieee80211_tx_pending(). Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Reviewed-by: Luis R.

2009-03-27mac80211: rewrite fragmentationJohannes Berg5-224/+173
Fragmentation currently uses an allocated array to store the fragment skbs, and then keeps track of which have been sent and which are still pending etc. This is rather complicated; make it simpler by just chaining the fragments into skb->next and removing from that list when sent. Also simplifies all code that needs to touch fragments, since it now only needs to walk the skb->next list. This is a prerequisite for fixing the stored packet code, which I need to do for proper aggregation packet storing. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Reviewed-by: Luis R.

2009-03-27cfg80211: fix locking in nl80211_set_wiphyJohannes Berg3-28/+33
Luis reports that there's a circular locking dependency; this is because cfg80211_dev_rename() will acquire the cfg80211_mutex while the device mutex is held, while this normally is done the other way around. The solution is to open-code the device-getting in nl80211_set_wiphy and require holding the mutex around cfg80211_dev_rename rather than acquiring it within. Also fix a bug -- rtnl locking is expected by drivers so we need to provide it. Reported-by: Luis R.

Such frames normally get dropped with a warning in __ieee80211_rx(), but it doesn't include enough information to track down the error.

The timer will still trigger during idle periods, that needs to be fixed later.

Until userspace and distributions catch up with a default userspace automatic replacement (GeoClue integration would be nirvana) we copy the ieee80211_regdom module parameter from OLD_REG to the new reg code to help these users migrate. Users who are using the non-valid ISO / IEC 3166 alpha "EU" in their ieee80211_regdom module parameter and migrate to non-OLD_REG enabled system will world roam. This also schedules removal of this same ieee80211_regdom module parameter circa March 2010. Hope is by then nirvana is reached and users will abandoned the module parameter completely.
