2012-05-08{nl,cfg,mac}80211: Allow user to see/configure HT protection modeAshok Nagarajan1-0/+5
This patch introduces a new mesh configuration parameter "ht_opmode" and will allow user to check the current HT protection mode selected. Users could configure the protection mode by the command "iw mesh_iface set mesh_param mesh_ht_protection_mode=2". The default protection mode of mesh is set to non-HT mixed mode.

2012-04-24mac80211: fix num_mcast_sta counting issuesFelix Fietkau1-0/+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.

2012-04-11cfg80211/mac80211: enable proper device_set_wakeup_enable handlingJohannes Berg1-0/+10
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.

2012-04-11mac80211: add improved HW queue controlJohannes Berg1-0/+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.

2012-03-05{nl,cfg,mac}80211: Implement RSSI threshold for mesh peeringAshok Nagarajan1-0/+8
Mesh peer links are established only if average rssi of the peer candidate satisfies the threshold. This is not in 802.11s specification but was requested by David Fulgham, an open80211s user.

The AP/GO mode API isn't very clearly defined, it has "set beacon" and "new beacon" etc. Modify the API to the following: * start AP -- all settings * change beacon -- new beacon data * stop AP -- stop AP mode operation This also reflects in the nl80211 API, rename the commands there correspondingly (but keep the old names for compatibility.) Overall, this makes it much clearer what's going on in the API. Kalle developed the ath6kl changes, I created the rest of the patch.

2012-02-06mac80211: redesign auth/assocJohannes Berg1-3/+3
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.

2012-01-30mac80211: station state transition error handlingJohannes Berg1-14/+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.

2012-01-13mac80211: fix no-op authorized transitionsJohannes Berg1-1/+1
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.

2011-12-15mac80211: refactor station state transitionsJohannes Berg1-15/+61
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.
