2013-01-03mac82011: use frame control to differentiate probe resp/beaconEmmanuel Grumbach4-48/+27
The probe response/beacon management frame RX code passes a bool parameter to differentiate beacons and probe responses. This is useless since we have the frame and can thus use its frame control field. Moreover it is buggy since there is one call to ieee80211_rx_bss_info with a beacon frame that is indicated as a probe response, which is also fixed by using the frame control field, so do that.

2013-01-03mac80211: optimise AP stop RCU handlingJohannes Berg4-9/+29
If there are VLANs, stopping an AP is inefficient as it calls rcu_barrier() once for each interface (the VLANs and the AP itself). Optimise this by moving rcu_barrier() out of the station cleanups and calling it only once for all interfaces combined. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2013-01-03regulatory: use RCU to protect global and wiphy regdomainsJohannes Berg3-65/+85
To simplify the locking and not require cfg80211_mutex (which nl80211 uses to access the global regdomain) and also to make it possible for drivers to access their wiphy->regd safely, use RCU to protect these pointers.

2013-01-03regulatory: remove handling of channel bandwidthJohannes Berg1-30/+14
The channel bandwidth handling isn't really quite right, it assumes that a 40 MHz channel is really two 20 MHz channels, which isn't strictly true. This is the way the regulatory database handling is defined right now though so remove the logic to handle other channel widths. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2013-01-03regulatory: fix reg_is_valid_request handlingJohannes Berg3-23/+17
There's a bug with the world regulatory domain, it can be updated any time which is different from all other regdomains that can only be updated once after a request for them. Fix this by adding a check for "processed" to the reg_is_valid_request() function and clear that when doing a request. While looking at this I also found another locking bug, last_request is protected by the reg_mutex not the cfg80211_mutex so the code in nl80211 is racy. Remove that code as it only tries to prevent an allocation in an error case, which isn't necessary. Then the function can also become static and locking in nl80211 can have a smaller scope. Also change __set_regdom() to do the checks earlier and not different for world/other regdomains. Acked-by: Luis R.

2013-01-03regulatory: remove locking from wiphy_apply_custom_regulatoryJohannes Berg1-4/+0

2013-01-03regulatory: clarify locking rules and assertionsJohannes Berg1-20/+11
Many places that currently check that cfg80211_mutex is held don't actually use any data protected by it. The functions that need to hold the cfg80211_mutex are the ones using the cfg80211_regdomain variable, so add the lock assertion to those and clarify this in the comments. The reason for this is that nl80211 uses the regdom without being able to hold reg_mutex. Acked-by: Luis R. Rodriguez <mcgrof@do-not-panic.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2013-01-03regulatory: simplify freq_reg_info_regdJohannes Berg1-15/+16
The function itself has dual-purpose: it can retrieve from a given regdomain or from the globally installed one. Change it to have a single purpose only: to look up from a given regdomain. Pass the correct regdomain in the freq_reg_info() function instead. This also changes the locking rules for it, no locking is required any more. Acked-by: Luis R.

2013-01-03mac80211: fix dtim_period in hidden SSID AP associationJohannes Berg3-37/+55
When AP's SSID is hidden the BSS can appear several times in cfg80211's BSS list: once with a zero-length SSID that comes from the beacon, and once for each SSID from probe reponses. Since the mac80211 stores its data in ieee80211_bss which is embedded into cfg80211_bss, mac80211's data will be duplicated too. This becomes a problem when a driver needs the dtim_period since this data exists only in the beacon's instance in cfg80211 bss table which isn't the instance that is used when associating. Remove the DTIM period from the BSS table and track it explicitly to avoid this problem.

This is a very old bug, but there's nothing that prevents the timer from running while the module is being removed when we only do del_timer() instead of del_timer_sync().

2013-01-03mac80211: fix station destruction in AP/mesh modesJohannes Berg4-17/+62
Unfortunately, commit b22cfcfcae5b, intended to speed up roaming by avoiding the synchronize_rcu() broke AP/mesh modes as it moved some code into that work item that will still call into the driver at a time where it's no longer expected to handle this: after the AP or mesh has been stopped. To fix this problem remove the per-station work struct, maintain a station cleanup list instead and flush this list when stations are flushed. To keep this patch smaller for stable, do this when the stations are flushed (sta_info_flush()). This unfortunately brings back the original roaming delay; I'll fix that again in a separate patch. Also, Ben reported that the original commit could sometimes (with many interfaces) cause long delays when an interface is set down, due to blocking on flush_workqueue(). Since we now maintain the cleanup list, this particular change of the original patch can be reverted.
