| * mac80211: add explicit IBSS driver operationsJohannes Berg2013-10-011-0/+35
| | | | | | | | | | | | | | | | | | This can be useful for drivers if they have any failure cases when joining an IBSS. Also move setting the queue parameters to before this new call, in case the new driver op needs them already. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

* mac80211: add channel switch command and beacon callbacksSimon Wunderlich2013-08-011-0/+26
| | | | | | | | | | | | | | | | The count field in CSA must be decremented with each beacon transmitted. This patch implements the functionality for drivers using ieee80211_beacon_get(). Other drivers must call back manually after reaching count == 0. This patch also contains the handling and finish worker for the channel switch command, and mac80211/chanctx code to allow to change a channel definition of an active channel context.

* mac80211: support secondary channel offset in CSAJohannes Berg2013-04-161-4/+4
| | | | | | | | | | | | | | | Add support for the secondary channel offset IE in channel switch announcements. This is necessary for proper handling of CSA on HT access points. For this to work it is also necessary to convert everything here to use chandef structs instead of just channels. The driver updates aren't really correct though. In particular, the TI wl18xx driver update can't possibly be right since it just ignores the new channel width for lack of firmware API. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
* mac80211: Use a cfg80211_chan_def in ieee80211_hw_conf_chanKarl Beldan2013-03-251-20/+17Star
| | | | | | | | | | Drivers that don't use chanctxes cannot perform VHT association because they still use a "backward compatibility" pair of {ieee80211_channel, nl80211_channel_type} in ieee80211_conf and ieee80211_local.

* mac80211: pass queue bitmap to flush operationJohannes Berg2013-03-181-4/+7
| | | | | | | | | | There are a number of situations in which mac80211 only really needs to flush queues for one virtual interface, and in fact during this frames might be transmitted on other virtual interfaces. Calculate and pass a queue bitmap to the driver so it knows which queues to flush. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
* mac80211: add driver callback for per-interface multicast filterAlexander Bondar2013-03-111-0/+24

* mac80211: add radar detection command/eventSimon Wunderlich2013-02-151-0/+19
| | | | | | | | | | | | | | | | Add command to trigger radar detection in the driver/FW. Once radar detection is started it should continuously monitor for radars as long as the channel active. If radar is detected usermode notified with 'radar detected' event. Scanning and remain on channel functionality must be disabled while doing radar detection/scanning, and vice versa.

* mac80211: introduce beacon-only timing dataJohannes Berg2013-02-111-0/+2
| | | | | | | | | | | | | | In order to be able to predict the next DTIM TBTT in the driver, add the ability to use timing data from beacons only with the new hardware flag IEEE80211_HW_TIMING_BEACON_ONLY and the BSS info value sync_dtim_count which is only valid if the timing data came from a beacon. The data can only come from a beacon, and if no beacon was received before association it is updated later together with the DTIM count notification.

* mac80211: fix chandef tracing bugJohannes Berg2013-02-111-1/+1

* mac80211: provide the vif in rssi_callbackEmmanuel Grumbach2013-01-241-3/+6

* mac80211: allow drivers to access IPv6 informationJohannes Berg2013-01-181-0/+8
| | | | | | | | | | | | | | To be able to implement NS response offloading (in regular operation or while in WoWLAN) drivers need to know the IPv6 addresses assigned to interfaces. Implement an IPv6 notifier in mac80211 to call the driver when addresses change. Unlike for IPv4, implement it as a callback rather than as a list in the BSS configuration, that is more flexible.

* mac80211: remove ARP filter enable/disable logicJohannes Berg2013-01-181-4/+9
| | | | | | | | | | | | Depending on the driver, having ARP filtering for some addresses may be possible. Remove the logic that tracks whether ARP filter is enabled or not and give the driver the total number of addresses instead of the length of the list so it can make its own decision.

* mac80211: add op to configure default key idYoni Divinsky2013-01-181-0/+23
| | | | | | | | | | | | | | | There are hardwares which support offload of data packets for example when auto ARP is enabled the hw will send the ARP response. In such cases if WEP encryption is configured the hw must know the default WEP key in order to encrypt the packets correctly. When hw_accel is enabled and encryption type is set to WEP, the driver should get the default key index from mac80211.

* mac80211: split out chandef tracing macrosJohannes Berg2013-01-161-9/+15
| | | | | | | | Some new APIs will require tracing a chandef without it being part of a channel context, so separate out the tracing macros for that. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
* mac80211: convert to channel definition structJohannes Berg2012-11-261-8/+15
| | | | | | | | | | | | | | Convert mac80211 (and where necessary, some drivers a little bit) to the new channel definition struct. This will allow extending mac80211 for VHT, which is currently restricted to channel contexts since there are no drivers using that which makes it easier. As I also don't care about VHT for drivers not using the channel context API, I won't convert the previous API to VHT support. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
* cfg80211: remove remain-on-channel channel typeJohannes Berg2012-11-261-4/+2Star
| | | | | | | | | | | | | | | | | As mwifiex (and mac80211 in the software case) are the only drivers actually implementing remain-on-channel with channel type, userspace can't be relying on it. This is the case, as it's used only for P2P operations right now. Rather than adding a flag to tell userspace whether or not it can actually rely on it, simplify all the code by removing the ability to use different channel types. Leave only the validation of the attribute, so that if we extend it again later (with the needed capability flag), it can't break userspace sending invalid data.

| | | | | | | | | | | | | Drivers (e.g. wl12xx) might need to know the vif to roc on (mainly in order to configure the rx filters correctly).

* mac80211: call driver method when restart completesJohannes Berg2012-11-091-0/+5
| | | | | | | | | | When the driver requests a restart (reconfiguration) it gets all the normal method calls, but can't really tell why they're happening. Call a new restart_complete op in the driver when the restart completes, so it could keep its own state about the restart and clear it there. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

* mac80211: handle TX power per virtual interfaceJohannes Berg2012-10-301-0/+2
| | | | | | | | | | | | | | | | | | | Even before channel contexts/multi-channel, having a single global TX power limit was already problematic, in particular if two managed interfaces connected to two APs with different power constraints. The channel context introduction completely broke this though and in fact I had disabled TX power configuration there for drivers using channel contexts. Change everything to track TX power per interface so that different user settings and different channel maxima are treated correctly. Also continue tracking the global TX power though for compatibility with applications that attempt to configure the wiphy's TX power globally. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
* mac80211: add explicit AP/GO driver operationsJohannes Berg2012-10-261-0/+37
| | | | | | | | | | Depending on the driver, a lot of setup may be necessary to start operating as an AP, some of which may fail. Add an explicit AP start driver method to make such failures easier to handle, and add an AP stop driver method for symmetry. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

* mac80211: track needed RX chains for channel contextsJohannes Berg2012-10-171-4/+9
| | | | | | | | | | | | | | | | | On each channel that the device is operating on, it may need to listen using one or more chains depending on the SMPS settings of the interfaces using it. The previous channel context changes completely removed this ability (before, it was available as the SMPS mode). Add per-context tracking of the required static and dynamic RX chains and notify the driver on changes. To achieve this, track the chains and SMPS mode used on each virtual interface and update the channel context whenever this changes. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

* mac80211: don't assume channel is set in tracingJohannes Berg2012-08-201-3/+6
| | | | | | | | | | | | | With the move to multi-channel and away from drv_config(), hw.conf.channel will not always be set, only for devices using the current API instead of the new channel context APIs. Check the channel is set before adding its frequency to the trace data. Also break some overly long lines in the code. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
* mac80211: support P2P Device abstractionJohannes Berg2012-08-201-1/+1
| | | | | | | | | | After cfg80211 got a P2P Device abstraction, add support to mac80211.

* mac80211: add time synchronisation with BSS for assocJohannes Berg2012-07-121-2/+4
| | | | | | | | | | | | | | | | | | | | | | | Some drivers (iwlegacy, iwlwifi and rt2x00) today use the bss_conf.last_tsf value. By itself though that value is completely worthless since it may be ancient. What really is needed is synchronisation between some device time and the TSF. To clarify this, rename bss_conf.last_tsf to sync_tsf and add sync_device_ts which is obtained from rx_status which gets a new field device_timestamp for this purpose. This is intentionally not using the mactime field since that is used for other things and in IBSS is expected to sync with the IBSS's TSF which isn't necessarily true for the device timestamp. Also, since we have the information and it's useful even before the connection has been established, give all the timing details to the driver before authenticating.

* mac80211: add TX prepare APIJohannes Berg2012-07-031-0/+7
| | | | | | | | | | | | | | | | | | Some drivers require setup before being able to send management frames in managed mode, in particular in multi-channel cases. Introduce API to allow the drivers to do such setup while being able to sleep waiting for the setup to finish in the device. This isn't possible inside the TX call since that can't sleep. A future patch may also restructure the TX retry to wait for the driver to report the frame status, as suggested by Arik in http://mid.gmane.org/CA+XVXffKSEL6ZQPQ98x-zO-NL2=TNF1uN==mprRyUmAaRn254g@mail.gmail.com Signed-off-by: Johannes Berg <johannes.berg@intel.com>
