2013-12-31iwlwifi: mvm: dynamically update tsf_idIlan Peer
Currently, the MAC context tsf_id assignment and the master/slave relations are determined only when a new vif is added, as part of the MAC context resource allocation. However, at this stage, the beacon interval is not known, and thus could not be taken into account in the master-slave algorithm. To fix this, recalculate the MAC context tsf_id assignment, just before the MAC context is activated, i.e., just before a station VMAC is configured to associated and before an AP VMAC is started.

Don't check if mvm->fw->cs is NULL since it can't be. cs is an array member of iwl_fw, it can't be NULL. Use memset(ptr, 0, sizeof(*ptr)); instead of memset(ptr, 0, sizeof(struct ptr_type)); Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2013-12-31iwlwifi: mvm: disable the device as soon as RFKILL firesEmmanuel Grumbach
The firmware needs to be stopped quickly (100ms) after the RFKILL interrupt fired. Failing to do so would allow the firmware to access the radio registers which would lead to a hardware error. Before this change, we would kill the firmware only when mac80211 stops the device which can take a fair amount of time. Take a shortcut by stopping the device right away in the interrupt. This is not relevant if the current firmware is INIT firmware since that firmware can run while in RFKILL. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2013-12-31iwlwifi: pcie: allow the op_mode to call stop_device whenever it wantsEmmanuel Grumbach
Calling stop_device when start_fw wasn't called would issue: Stopping tx queues that aren't allocated... Also allow the op_mode to call stop_device and then to disable the Tx queues - in that case just silently ignore the disabling on the Tx queues, since the PRPH registers aren't reachable any more.

2013-12-31iwlwifi: pcie: don't update the op_mode if rfkill hasn't changedEmmanuel Grumbach
This is useless and introduces a dependency between rfkill and stop_device - the op_mode can't call stop_device from the rfkill notification since it would lead to an endless recursion. Next patches will need to do so. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2013-12-31iwlwifi: pcie: keep the NIC awake when commands are in flightEmmanuel Grumbach
Under very specific circumstances, the firmware might ignore a host command. This was debugged and we ended up seeing that the power management hardware was faulty. In order to workaround this issue, we keep the NIC awake as long as we have host commands in flight. This will avoid to put the hardware into buggy condition.

2013-12-31iwlwifi: mvm: fix AC / FIFO mappingEmmanuel Grumbach
The AC / fifo mapping was wrong - BE packets landed in VO FIFO. The iwl_mvm_tx_fifo enumeration isn't in the same order as ieee80211_ac_numbers enumeration. Since the firmware relies on fifo / ac mapping - this led to wrong behavior. E.g. the firmware sends beacon with the same QoS parameters as VO, and it actually took the parameters of BK. There are probably more severe issues. Reviewed-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

This lock was never acquired in the primary interrupt handler, but since it was acquired along with irq_lock which had to disable interrupts, rxq->lock had to disable interrupts too.

This allows QoS mapping from external networks to be implemented as defined in IEEE Std 802.11-2012, 10.24.9. APs can use this to advertise DSCP ranges and exceptions for mapping frames to a specific UP over Wi-Fi. The payload of the QoS Map Set element (IEEE Std 802.11-2012, 8.4.2.97) is sent to the driver through the new NL80211_ATTR_QOS_MAP attribute to configure the local behavior either on the AP (based on local configuration) or on a station (based on information received from the AP).

2013-12-19mac80211: fix iflist_mtx/mtx locking in radar detectionJohannes Berg
The scan code creates an iflist_mtx -> mtx locking dependency, and a few other places, notably radar detection, were creating the opposite dependency, causing lockdep to complain. As scan and radar detection are mutually exclusive, the deadlock can't really happen in practice, but it's still bad form. A similar issue exists in the monitor mode code, but this is only used by channel-context drivers right now and those have to have hardware scan, so that also can't happen. Still, fix these issues by making some of the channel context code require the mtx to be held rather than acquiring it, thus allowing the monitor/radar callers to keep the iflist_mtx->mtx lock ordering. While at it, also fix access to the local->scanning variable in the radar code, and document that radar_detect_enabled is now properly protected by the mtx. All this would now introduce an ABBA deadlock between the DFS work cancelling and local->mtx, so change the locking there a bit to not need to use cancel_delayed_work_sync() but be able to just use cancel_delayed_work(). The work is also safely stopped/removed when the interface is stopped, so no extra changes are needed.

2013-12-19mac80211: remove unnecessary iflist_mtx lockingJohannes Berg
The radar detection code changed a few times, and due to the changes some iflist_mtx locking stayed in that isn't actually necessary - remove it. One version of the code needed it because an AP interface's VLAN list was changed to use this, but then we moved the list handling outside of the chanctx handling and thus the locking was no longer needed.
