2009-08-20mac80211: remove deprecated APIJohannes Berg
All but two drivers have now stopped using the two deprecated members radio_enabled and beacon_int, so it's about time to remove them for good. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Acked-by: Kalle Valo <kalle.valo@iki.fi> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2009-08-20mac80211: allow configure_filter callback to sleepJohannes Berg
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.

2009-08-04mac80211: redefine usage of the mac80211 workqueueLuis R. Rodriguez
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.

2009-08-04at76c50x-usb: remove unneeded flush_workqueue() at usb disconnectLuis R. Rodriguez
This driver only uses the mac80211 workqueue and mac80211 requires us to cancel all work at driver stop. Since we now have the cancels in the right places at stop() we really don't need to flush the mac80211 workqueue so remove it. Signed-off-by: Luis R.

2009-08-04at76c50x-usb: cancel scan work at stop callbackLuis R. Rodriguez
This should fix suspend as mac80211 expects all work queued to the mac80211 workqueue to be canceled at driver stop(). Signed-off-by: Luis R. Rodriguez <lrodriguez@atheros.com> Acked-by: Kalle Valo <kalle.valo@iki.fi> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2009-07-10mac80211: push rx status into skb->cbJohannes Berg
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>

2009-05-29at76c50x-usb: avoid mutex deadlock in at76_dwork_hw_scanJohn W. Linville
http://bugzilla.kernel.org/show_bug.cgi?id=13312 at76_dwork_hw_scan holds a mutex while calling ieee80211_scan_completed, which then calls at76_config which needs the same mutex. This reworks the ordering to not hold the lock while calling ieee80211_scan_completed. Signed-off-by: John W. Linville <linville@tuxdriver.com>
2009-05-06mac80211: unify config_interface and bss_info_changedJohannes Berg
The config_interface method is a little strange, it contains the BSSID and beacon updates, while bss_info_changed contains most other BSS information for each interface. This patch removes config_interface and rolls all the information it previously passed to drivers into bss_info_changed.

2009-04-22cfg80211: introduce scan IE limit attributeJohannes Berg
This patch introduces a new attribute for a wiphy that tells userspace how long the information elements added to a probe request frame can be at most. It also updates the at76 to advertise that it cannot support that, and, for now until I can fix that, iwlwifi too. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

2009-02-27at76c50x-usb: additional disconnect fixesJason Andryuk
Additional attempts to fix Oops on disconnect, that appear to be successful. However, some may be extraneous. The cancel_delayed_work call is probably the most necessary. The device_unplugged check may not be necessary. del_timer_sync may not be necessary either, but the Oops I was receiving was related to timers. Hence the addition.

flush_workqueue needs to be called instead of the generic one and the associated functions need to be modified to prevent re-adding themselves to the workqueue.
