* mac80211: move synchronize_net() before sta key removalJohannes Berg2013-12-162-14/+5
| | | | | | | | | | | | 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>
* mac80211: don't delay station destructionJohannes Berg2013-12-167-119/+12
| | | | | | | | | | | | 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.

* mac80211: move 4-addr sta pointer clearing before synchronize_rcu()Johannes Berg2013-12-161-3/+4
| | | | | | | | | | | | | 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.)

* iwlwifi: mvm: use pre-RCU-sync sta removal operationJohannes Berg2013-12-163-7/+40
| | | | | | | | | | | | | | | | | 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.

* mac80211: add pre-RCU-sync sta removal driver operationJohannes Berg2013-12-164-21/+52
| | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The values in l2cap_chan that are used for actually transmitting data only need to be initialized right after we've received an L2CAP Connect Request or just before we send one.

This way all other initializations can be done in the l2cap_le_flowctl_init function (which now becomes private to l2cap_core.c) and the l2cap_le_flowctl_start function can be completely removed. Also, since the l2cap_sock_init function initializes the imtu and omtu to adequate values these do not need to be part of l2cap_le_flowctl_init.
