* mac80211: fix num_mcast_sta counting issuesFelix Fietkau2012-04-241-0/+19
| | | | | | | | | | | | | | | | Moving a STA to an AP VLAN prevents num_mcast_sta from being decremented once the STA leaves, because sta->sdata changes. Fix this by checking for AP VLANs as well. Also exclude 4-addr VLAN stations from num_mcast_sta - remote 4-addr stations ignore 3-address multicast frames anyway. In a typical bridge configuration they receive the same packets as 4-address unicast. This patch also fixes clearing the sdata->u.vlan.sta pointer when the STA is removed from a 4-addr VLAN.

| | | | | | | | | | | | | | In WoWLAN, we only get the triggers when we actually get to suspend. As a consequence, drivers currently don't know that the device should enable wakeup. However, the device_set_wakeup_enable() API is intended to be called when the wakeup is enabled, not later when needed. Add a new set_wakeup() call to cfg80211 and mac80211 to allow drivers to properly call device_set_wakeup_enable. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W.

* mac80211: add improved HW queue controlJohannes Berg2012-04-111-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | mac80211 currently only supports one hardware queue per AC. This is already problematic for off-channel uses since if we go off channel while the BE queue is full and then try to send an off-channel frame the frame will never go out. This will become worse when we support multi-channel since then a queue on one channel might be full, but we have to stop the software queue for all channels. That is obviously not desirable. To address this problem allow drivers to register more hardware queues, and allow them to map them to virtual interfaces. When they stop a hardware queue the corresponding AC software queues on the correct interfaces will be stopped as well. Additionally, there's an off-channel queue to solve that problem and a per-interface after-DTIM beacon queue. This allows drivers to manage software queues closer to how the hardware works. Currently, there's a limit of 16 hardware queues. This may or may not be sufficient, we can adjust it as needed. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W.

| | | | | | | | | | | | | | | | | | This is the second part of the auth/assoc redesign, the mac80211 part. This moves the auth/assoc code out of the work abstraction and into the MLME, so that we don't flip channels all the time etc. The only downside is that when we are associated, we need to drop the association in order to create a connection to another AP, but for most drivers this is actually desirable and the ability to do was never used by any applications. If we want to implement resource reservation with FT-OTA, we'd probably best do it with explicit R-O-C in wpa_s. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W.

* mac80211: station state transition error handlingJohannes Berg2012-01-301-14/+8
| | | | | | | | | | | | | | | | | | | | | | | In the future, when we start notifying drivers, state transitions could potentially fail. To make it easier to distinguish between programming bugs and driver failures: * rename sta_info_move_state() to sta_info_pre_move_state() which can only be called before the station is inserted (and check this with a new station flag). * rename sta_info_move_state_checked() to just plain sta_info_move_state(), as it will be the regular function that can fail for more than just one reason (bad transition or an error from the driver) This makes the programming model easier -- one of the functions can only be called before insertion and can't fail, the other can fail.

| | | | | | | | | | | | | | | | | | | | | | | When userspace attempts to authorize a station that is already authorized, nothing happens as you'd expect. Similarly, when it unauthorizes a station that is associated, nothing happens. However, when it unauthorizes a station that isn't even associated yet, we erroneously try to move the station to associated. This seems to happen occasionally as a result of a race when wpa_supplicant attempts to unauthorize the port in managed mode. Particularly with my new patches to keep stations, it can then move a station into ASSOCIATED state before we have really associated, which is really confusing.

| | | | | | | | | | | | | | | | | | | | | | | | Station entries can have various states, the most important ones being auth, assoc and authorized. This patch prepares us for telling the driver about these states, we don't want to confuse drivers with strange transitions, so with this we enforce that they move in the right order between them (back and forth); some transitions might happen before the driver even knows about the station, but at least runtime transitions will be ordered correctly. As a consequence, IBSS and MESH stations will now have the ASSOC flag set (so they can transition to AUTHORIZED), and we can get rid of a special case in TX processing. When freeing a station, unwind the state so that other parts of the code (or drivers later) can rely on the transitions. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W.

* mac80211: init rate-control for TDLS sta when supp-rates are knownArik Nemtsov2011-11-111-1/+9
| | | | | | | | | | Initialize rate control algorithms only when supported rates are known for a TDLS peer sta. Direct Tx between peers is not allowed before the link is enabled. In turn, this only occurs after a change_station() call that sets supported rates. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* cfg80211/mac80211: allow management TX to not wait for ACKJohannes Berg2011-11-091-3/+8
| | | | | | | | | | | | | | For probe responses it can be useful to not wait for ACK to avoid retransmissions if the station that sent the probe is already on the next channel, so allow userspace to request not caring about the ACK with a new nl80211 flag. Since mac80211 needs to be updated for the new function prototype anyway implement it right away -- it's just a few lines of code.
