2009-02-27cfg80211: pass the regulatory_request struct in __regulatory_hint()Luis R. Rodriguez

2009-02-27ath9k: follow beacon hints on reg_notifier when world roamingLuis R. Rodriguez
If we are roaming we allow to follow beacon hints. Signed-off-by: Luis R. Rodriguez <lrodriguez@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2009-02-27cfg80211: Add AP beacon regulatory hintsLuis R. Rodriguez
When devices are world roaming they cannot beacon or do active scan on 5 GHz or on channels 12, 13 and 14 on the 2 GHz band. Although we have a good regulatory API some cards may _always_ world roam, this is also true when a system does not have CRDA present. Devices doing world roaming can still passive scan, if they find a beacon from an AP on one of the world roaming frequencies we make the assumption we can do the same and we also remove the passive scan requirement. This adds support for providing beacon regulatory hints based on scans. This works for devices that do either hardware or software scanning. If a channel has not yet been marked as having had a beacon present on it we queue the beacon hint processing into the workqueue. All wireless devices will benefit from beacon regulatory hints from any wireless device on a system including new devices connected to the system at a later time. Signed-off-by: Luis R.

2009-02-27cfg80211: enable 5 GHz world roaming channelsLuis R. Rodriguez
The current static world regulatory domain is too restrictive, we can use some 5 GHz channels world wide so long as they do not touch frequencies which require DFS. The compromise is we must also enforce passive scanning and disallow usage of a mode of operation that beacons: (AP | IBSS | Mesh) Signed-off-by: Luis R.

Truth of the matter this was confusing people so mark it as unlikely as that is the case now. Signed-off-by: Luis R. Rodriguez <lrodriguez@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2009-02-27cfg80211: protect first access of last_request on 11d hint under mutexLuis R. Rodriguez
We were not protecting last_request there is a small possible race between an 11d hint and another routine which calls reset_regdomains() which can prevent a valid country IE from being processed. This is not critical as it will still be procesed soon after but locking prior to it is correct. Signed-off-by: Luis R. Rodriguez <lrodriguez@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2009-02-27cfg80211: make regulatory_request use wiphy_idx instead of wiphyLuis R. Rodriguez
We do this so later on we can move the pending requests onto a workqueue. By using the wiphy_idx instead of the wiphy we can later easily check if the wiphy has disappeared or not. Signed-off-by: Luis R. Rodriguez <lrodriguez@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2009-02-27cfg80211: propagate -ENOMEM during regulatory_init()Luis R. Rodriguez
Calling kobject_uevent_env() can fail mainly due to out of memory conditions. We do not want to continue during such conditions so propagate that as well instead of letting cfg80211 load as if everything is peachy. Additionally lets clarify that when CRDA is not called during cfg80211's initialization _and_ if the error is not an -ENOMEM its because kobject_uevent_env() failed to call CRDA, not because CRDA failed. For those who want to find out why we also let you do so by enabling the kernel config CONFIG_CFG80211_REG_DEBUG -- you'll get an actual stack trace. So for now we'll treat non -ENOMEM kobject_uevent_env() failures as non fatal during cfg80211's initialization. CC: Greg KH <greg@kroah.com> Signed-off-by: Luis R.

2009-02-27cfg80211: add regulatory_hint_core() to separate the core reg hintLuis R. Rodriguez
This makes the core hint path more readable and allows for us to later make it obvious under what circumstances we need locking or not. Signed-off-by: Luis R. Rodriguez <lrodriguez@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2009-02-27nl80211: disallow user requests prior to regulatory_init()Luis R. Rodriguez
If cfg80211 is built into the kernel there is perhaps a small time window betwen nl80211_init() and regulatory_init() where cfg80211_regdomain hasn't yet been initialized to let the wireless core do its work. During that rare case and time frame (if its even possible) we don't allow user regulatory changes as cfg80211 is working on enabling its first regulatory domain. To check for cfg80211_regdomain we now contend the entire operation using the cfg80211_mutex. Signed-off-by: Luis R. Rodriguez <lrodriguez@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2009-02-27cfg80211: rename cfg80211_drv_mutex to cfg80211_mutexLuis R. Rodriguez

2009-02-27cfg80211: add wiphy_idx_valid to check for wiphy_idx sanityLuis R. Rodriguez

2009-02-27ath9k: Don't reset TSF after scanning automaticallyAlina Friedrichsen
Reset automatically the TSF on re-enabling beaconing after scanning in IBSS mode causes several problems. For example a new created IBSS network can't age before an other node has joined, because scans are done automatically in that case. And several other strange bugs more... The TSF reset is done manually in the higher level mac80211 code in the cases were it's needed, so we don't need to do it here.

2009-02-27b43: Optimize DMA buffersMichael Buesch
In the old days we used one slot per frame. But when we changed that to 2, we didn't raise the overall slot count. Which resulted in an effective division of two to the number of slots. Double the number of TX slots, so we have an effective hardware queue of 128 frames per QoS queue. Also optimize the TX header cache handling. We don't need a cached TX header for slots that will never carry an actual header. So we reduce the memory consumption of the cache by 50%. So as a net result we end up with more or less the same memory usage before and after this patch (except a few tiny meta structures), but have twice the number of TX slots available.

2009-02-27b43: Fix DMA buffer size handlingMichael Buesch
This fixes hidden bugs in the size handling of the DMA buffers. This sets the RX buffer size to the theoretical max packet size and fixes passing of the size values to the device (must not subtract the header offset). These bugs are hidden and don't actually trigger due to the magic +100 offset for the buffer size. Signed-off-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: John W.

2009-02-27iwlwifi: dma mapping read and write changesFenghua Yu
When iwlwifi runs on IOMMU, IOMMU generates a lot of PTE write faults because PTE write bit is not set on some of PTE's. This is because iwlwifi driver calls DMA mapping with PCI_DMA_TODEVICE which is read only in mapping PTE. But iwlwifi device actually writes to the mapped page to update its contents. This issue is not exposed in swiotlb. But VT-d hardware can capture this fault and stop the fault transaction. The iwl TX command contains a scratch field that is updated by uCode to indicate retry counts. For 5000 series the patch is required also for regular frames, but this patch does not differenciate.
