The return value of ieee80211_ibss_csa_beacon is not aligned with the return value of ieee80211_assign_beacon(). For consistency and to be able to use both functions with similar code, change ieee80211_ibss_csa_beacon() not to send the bss changed notification itself, but return what has changed so the caller can send the notification instead.

This regression was introduced in "mac80211: cache mesh beacon". mesh_sync_offset_adjust_tbtt() was assuming that the beacon would be rebuilt in every single pre-tbtt interrupt, but now the beacon update happens on the workqueue, and it must be ready for immediate delivery to the driver. Save a pointer to the meshconf IE in the beacon_data (this works because both the IE pointer and beacon buffer are protected by the same rcu_{dereference,assign_pointer}()) for quick updates during pre-tbtt. This is faster and a little prettier than iterating over the elements to find the meshconf IE every time.

When the AP interface is stopped, free all AP and VLAN keys at once to only require synchronize_net() once. Since that does synchronize_net(), also move two such calls into the function (using the new force_synchronize parameter) to avoid doing it twice.

Teach sta_info_flush() to optionally also remove stations from all VLANs associated with an AP interface to optimise the station removal (in particular, synchronize_net().) To not have to add the vlans argument throughout, do some refactoring. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

Johannes Berg authored
There's no reason to have one synchronize_net() for each removed station, refactor the code slightly to have just a single synchronize_net() for all stations. Note that this is currently useless as hostapd removes stations one by one and this coalescing never happens. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
-
Johannes Berg authored
There's no reason to do this inside the sta key removal since the keys can only be reached through the sta (and not by the driver at all) so once the sta can no longer be reached, the keys are safe. This will allow further optimisation opportunities with multiple stations. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
-
Johannes Berg authored
If we can assume that stations are never referenced by the driver after sta_state returns (and this is true since the previous iwlmvm patch and for all other drivers) then we don't need to delay station destruction, and don't need to play tricks with rcu_barrier() etc. This should speed up some scenarios like hostapd shutdown.

The pointer should be cleared before synchronize_rcu() so that the consequently dead station won't be found by any lookups in the TX or RX paths. Also check that the station is actually the one being removed, the check is not needed because each 4-addr VLAN can only have a single station and non-4-addr VLANs always have a NULL pointer there, but the code is clearer this way (and we avoid the memory write.)

iwlmvm relies on the current mac80211 behaviour of allowing station pointers to be valid for an RCU grace period after returning from the sta_state() callback. To optimise these cases, this behaviour is going away, so make the driver use the new sta_pre_rcu_remove() method to clear the pointer in the fw_id_to_mac_id[] array. Since this may happen while the station is still present in the firmware, don't set the pointer to NULL but to -ENOENT to mark this particular case. In client mode, the station is kept even longer (until marking the MAC as unassociated) so the drain flow must take this new behavior into account.

Currently, mac80211 allows drivers to keep RCU-protected station references that are cleared when the station is removed from the driver and consequently needs to synchronize twice, once before removing the station from the driver (so it can guarantee that the station is no longer used in TX towards the driver) and once after the station is removed from the driver. Add a new pre-RCU-synchronisation station removal operation to the API to allow drivers to clear/invalidate their RCU-protected station pointers before the RCU synchronisation. This will allow removing the second synchronisation by changing the driver API so that the driver may no longer assume a valid RCU-protected pointer after sta_remove/sta_state returns. The alternative to this would be to synchronize_rcu() in all the drivers that currently rely on this behaviour (only iwlmvm) but that would defeat the purpose.

Some cards don't update the PISR properly when all SISR bits for Tx interrupts are being cleared and as a result we get interrupt storm. Since we handle all tx queues all together (so we don't really use the SISR bits to do per-queue interrupt handling), we can manualy update PISR by doing a write-to-clear on its Tx interrupt bits.

If we receive an L2CAP command reject message over LE we should take appropriate action on the corresponding channel. This is particularly important when trying to interact with a remote pre-4.1 system using LE CoC signaling messages. If we don't react to the command reject the corresponding socket would not be notified until a connection timeout occurs.
