| * | ath9k: Fix RFKILL bugsSujith2009-09-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes 2 issues in RFKILL: * Calling wiphy_rfkill_stop_polling() in ath9k_stop would mean that the driver cannot report HW status when the radio is re-enabled. Move this to ath_detach(). * Calling ath_radio_{enable/disable} without checking the current state results in ath_radio_enable() being called repeatedly for every invocation of rfkill_poll(). This is not needed in any case since wiphy_rfkill_set_hw_state() would call ->stop() if the radio has been disabled.

| * | iwlwifi: reduce noise when skb allocation failsReinette Chatre2009-09-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replenishment of receive buffers is done in the tasklet handling received frames as well as in a workqueue. When we are in the tasklet we cannot sleep and thus attempt atomic skb allocations. It is generally not a big problem if this fails since iwl_rx_allocate is always followed by a call to iwl_rx_queue_restock which will queue the work to replenish the buffers at a time when sleeping is allowed. We thus add the __GFP_NOWARN to the skb allocation in iwl_rx_allocate to reduce the noise if such an allocation fails while we still have enough buffers. We do maintain the warning and the error message when we are low on buffers to communicate to the user that there is a potential problem with memory availability on system This addresses issue reported upstream in thread "iwlagn: order 2 page allocation failures" in http://thread.gmane.org/gmane.linux.kernel.wireless.general/39187 Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Acked-by: Mel Gorman <mel@csn.ul.ie> Signed-off-by: John W.

| * | iwlwifi: do not send sync command while holding spinlockReinette Chatre2009-09-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 10c994ca70e8e94bbc85a5bf13de5911ee8de4d2 "iwlwifi: fix remove key error" fixed an error reported by mac80211 during interface down. The fix involved changing an async command to synchronous. Unfortunately this was inside a spinlock section in which we cannot sleep. Modify the sending of the command back to async. This causes the mac80211 error "mac80211-phy0: failed to remove key (0, ff:ff:ff:ff:ff:ff) from hardware (-16)." to return. This error is not serious since this occurs during interface down and the keys will be cleared anyway when ucode is unloaded. Having this error message is thus less serious than a potential deadlock introduced when sleeping while holding a spinlock. We will have to find another fix for that error. This is a revert of the abovementioned commit. Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's a bug in 4965 powersave that appears to be related to the way it keeps track of its data during sleep, but we haven't found it yet. Due to that, using powersave may spontaneously cause the device to SYSASSERT when transitioning from sleep to wake. Therefore, disable powersave for 4965, until (if ever, unfortunately) we can identify and fix the problem.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RX handling maintains a few lists that keep track of the RX buffers. Buffers move from one list to the other as they are used, replenished, and again made available for usage. In one such instance, when a buffer is used it enters the "rx_used" list. When buffers are replenished an skb is attached to the buffer and it is moved to the "rx_free" list. The problem here is that the buffer is first removed from the "rx_used" list _before_ the skb is allocated. Thus, if the skb allocation fails this buffer remains removed from the "rx_used" list and is thus lost for future usage. Fix this by first allocating the skb before trying to attach it to a list. We add an additional check to not do this unnecessarily. Reported-by: Rick Farrington <rickdic@hotmail.com> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Signed-off-by: John W.

Originally, the tx_queue_len was set to 0 for every other interface than HOSTAP_INTERFACE_MASTER, but the new fragment of code sets tx_queue_len to 0 only for HOSTAP_INTERFACE_MASTER. The opposite of the previous behavior makes the driver to drop all packets in AP mode. Change the way 0 is assigned to tx_queue_len according to the original logic.

* | iwlwifi: disable powersave for 4965Johannes Berg2009-09-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's a bug in 4965 powersave that appears to be related to the way it keeps track of its data during sleep, but we haven't found it yet. Due to that, using powersave may spontaneously cause the device to SYSASSERT when transitioning from sleep to wake. Therefore, disable powersave for 4965, until (if ever, unfortunately) we can identify and fix the problem. Cf. http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=1982 which was closed, but now has re-appeared with IDLE mode, which probably means we never really fixed it.

* | iwlwifi: fix potential rx buffer lossReinette Chatre2009-09-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RX handling maintains a few lists that keep track of the RX buffers. Buffers move from one list to the other as they are used, replenished, and again made available for usage. In one such instance, when a buffer is used it enters the "rx_used" list. When buffers are replenished an skb is attached to the buffer and it is moved to the "rx_free" list. The problem here is that the buffer is first removed from the "rx_used" list _before_ the skb is allocated. Thus, if the skb allocation fails this buffer remains removed from the "rx_used" list and is thus lost for future usage. Fix this by first allocating the skb before trying to attach it to a list. We add an additional check to not do this unnecessarily. Reported-by: Rick Farrington <rickdic@hotmail.com> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Signed-off-by: John W.

* | b43: Fix resume failureMichael Buesch2009-09-14
| | | | | | | | | | | | | | | | | | | | | | | | This fixes a resume failure where a signal is pending on resume so the firmware upload fails. This removes the interruptible sleep, because we don't really need it. In the worst case (with broken firmware) the sleep loop will take 1 second. In the common case (working firmware), it will only take a few milliseconds. So we don't really need to be interruptible. Signed-off-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: John W.
