* mac80211: allow configure_filter callback to sleepJohannes Berg2009-08-20
| | | | | | | | | | | | | | | | | | | | | Over time, a whole bunch of drivers have come up with their own scheme to delay the configure_filter operation to a workqueue. To be able to simplify things, allow configure_filter to sleep, and add a new prepare_multicast callback that drivers that need the multicast address list implement. This new callback must be atomic, but most drivers either don't care or just calculate a hash which can be done atomically and then uploaded to the hardware non-atomically. A cursory look suggests that at76c50x-usb, ar9170, mwl8k (which is actually very broken now), rt2x00, wl1251, wl1271 and zd1211 should make use of this new capability.

* b43legacy: Work around mac80211 race conditionLarry Finger2009-08-04
| | | | | | | | | | | | | | | | As shown in http://thread.gmane.org/gmane.linux.kernel.wireless.general/36497, mac80211 has a bug that allows a call to the TX routine after the queues have been stopped. This situation will only occur under extreme stress. Although b43legacy does not crash when this condition occurs, it does generate a WARN_ON and also logs a queue overrun message. This patch recognizes b43legacy is not at fault and logs a message only when the most verbose debugging mode is enabled. In the unlikely event that the queue is not stopped when the DMA queue becomes full, then a warning is issued. This patch is based on the one used by b43.

* mac80211: redefine usage of the mac80211 workqueueLuis R. Rodriguez2009-08-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The mac80211 workqueue exists to enable mac80211 and drivers to queue their own work on a single threaded workqueue. mac80211 takes care to flush the workqueue during suspend but we never really had requirements on drivers for how they should use the workqueue in consideration for suspend. We extend mac80211 to document how the mac80211 workqueue should be used, how it should not be used and finally move raw access to the workqueue to mac80211 only. Drivers and mac80211 use helpers to queue work onto the mac80211 workqueue: * ieee80211_queue_work() * ieee80211_queue_delayed_work() These helpers will now warn if mac80211 already completed its suspend cycle and someone is trying to queue work. mac80211 flushes the mac80211 workqueue prior to suspend a few times, but we haven't taken the care to ensure drivers won't add more work after suspend. To help with this we add a warning when someone tries to add work and mac80211 already completed the suspend cycle. Drivers should ensure they cancel any work or delayed work in the mac80211 stop() callback. Signed-off-by: Luis R. Rodriguez <lrodriguez@atheros.com> Signed-off-by: John W.

* mac80211: push rx status into skb->cbJohannes Berg2009-07-10
| | | | | | | | | | | | | | | Within mac80211, we often need to copy the rx status into skb->cb. This is wasteful, as drivers could be building it in there to start with. This patch changes the API so that drivers are expected to pass the RX status in skb->cb, now accessible as IEEE80211_SKB_RXCB(skb). It also updates all drivers to pass the rx status in there, but only by making them memcpy() it into place before the call to the receive function (ieee80211_rx(_irqsafe)). Each driver can now be optimised on its own schedule. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch completely rewrites the rfkill core to address the following deficiencies: * all rfkill drivers need to implement polling where necessary rather than having one central implementation * updating the rfkill state cannot be done from arbitrary contexts, forcing drivers to use schedule_work and requiring lots of code * rfkill drivers need to keep track of soft/hard blocked internally -- the core should do this * the rfkill API has many unexpected quirks, for example being asymmetric wrt. alloc/free and register/unregister * rfkill can call back into a driver from within a function the driver called -- this is prone to deadlocks and generally should be avoided * rfkill-input pointlessly is a separate module * drivers need to #ifdef rfkill functions (unless they want to depend on or select RFKILL) -- rfkill should provide inlines that do nothing if it isn't compiled in * the rfkill structure is not opaque -- drivers need to initialise it correctly (lots of sanity checking code required) -- instead force drivers to pass the right variables to rfkill_alloc() * the documentation is hard to read because it always assumes the reader is completely clueless and contains way TOO MANY CAPS * the rfkill code needlessly uses a lot of locks and atomic operations in locked sections * fix LED trigger to actually change the LED when the radio state changes -- this wasn't done before Tested-by: Alan Jenkins <alan-jenkins@tuffmail.co.uk> Signed-off-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br> [thinkpad] Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

* mac80211: clean up beacon interval settingsJohannes Berg2009-05-06
| | | | | | | | | | | | | | | | | | | | We currently have two beacon interval configuration knobs: hw.conf.beacon_int and vif.bss_info.beacon_int. This is rather confusing, even though the former is used when we beacon ourselves and the latter when we are associated to an AP. This just deprecates the hw.conf.beacon_int setting in favour of always using vif.bss_info.beacon_int. Since it touches all the beaconing IBSS code anyway, we can also add support for the cfg80211 IBSS beacon interval configuration easily. NOTE: The hw.conf.beacon_int setting is retained for now due to drivers still using it -- I couldn't untangle all drivers, some are updated in this patch.

This patch also adds temporary code to the rt2x00 drivers to not break them completely, that code will have to be reworked for proper sequence numbers on beacons.

* b43legacy: Remove switch statement with 64-bit indexLarry Finger2008-07-08
| | | | | | | | | | | | The gcc 3.4 fork used to compile the MN10300 port emits unwanted __ucmpdi2() calls for switch statements that use a 64bit value. This patch removes such a switch from b43legacy, and makes the code more like that used in b43. Thanks to Adrian Bunk <bunk@kernel.org> for reporting the problem.
