* mac80211: notify drivers on sta rate table changesJohannes Berg2014-11-191-0/+6
| | | | | | | | | This allows drivers with a firmware or chip-based rate lookup table to use the most recent default rate selection without having to get it from per-packet data or explicit ieee80211_get_tx_rate calls Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: Johannes Berg <johannes.berg@intel.com>

* mac80211: synchronously reserve TID per stationLiad Kaufman2014-11-191-0/+37
| | | | | | | | | | | | | | In TDLS (e.g., TDLS off-channel) there is a requirement for some drivers to supply an unused TID between the AP and the device to the FW, to allow sending PTI requests and to allow the FW to aggregate on a specific TID for better throughput. To ensure that the allocated TID is indeed unused, this patch introduces an API for blocking the driver from TXing on that TID.

* mac80211: introduce TDLS channel switch opsArik Nemtsov2014-11-191-0/+19
| | | | | | | | | | | | | | | | Implement the cfg80211 TDLS channel switch ops and introduce new mac80211 ones for low-level drivers. Verify low-level driver support for the new ops when using the relevant wiphy feature bit. Also verify the peer supports channel switching before passing the command down. Add a new STA flag to track the off-channel state with the TDLS peer and make sure to cancel the channel-switch if the peer STA is unexpectedly removed.

* mac80211: 802.11p OCB mode supportRostislav Lisovy2014-11-041-0/+2
| | | | | | | | | | | | | | | | | | | | | | This patch adds 802.11p OCB (Outside the Context of a BSS) mode support. When communicating in OCB mode a mandatory wildcard BSSID (48 '1' bits) is used. The EDCA parameters handling function was changed to support 802.11p specific values. The insertion of a newly discovered STAs is done in the similar way as in the IBSS mode -- through the deferred insertion. The OCB mode uses a periodic 'housekeeping task' for expiration of disconnected STAs (in the similar manner as in the MESH mode). New Kconfig option for verbose OCB debugging outputs is added.

* mac80211: add WMM admission control supportJohannes Berg2014-10-221-1/+2
| | | | | | | | | | | | | | | | | | | | Use the currently existing APIs between mac80211 and the low level driver to implement WMM admission control. The low level driver needs to report the media time used by each transmitted packet in ieee80211_tx_status. Based on that information, mac80211 will modify the QoS parameters of the admission controlled Access Category when the limit is reached. Once the original QoS parameters can be restored, mac80211 will do so. One issue with this approach is that management frames will also erroneously be downgraded, but the upside is that the implementation is simple. In the future, it can be extended to driver- or device-based implementations that are better.

* mac80211: add a single-transaction driver op to switch contextsLuciano Coelho2014-05-261-0/+46
| | | | | | | | | | | | | | | | In some cases, when the driver is already using all the channel contexts it can handle at once, we have to do an in-place switch (ie. we cannot afford using an extra context temporarily for the transaction). But some drivers may not support switching the channel context assigned to a vif on the fly (ie. without unassigning and assigning it) while others may only work if the context is changed on the fly, without unassigning it first. To allow these different scenarios, add a new driver operation that let's the driver decide how to handle an in-place switch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | It was possible for tx queues to be stuck stopped if AP CSA finalization failed. In that case neither stop_ap nor do_stop woke the queues up. This means it was impossible to perform tx at all until driver was reloaded or a successful CSA was performed later. It was possible to solve this in a simpler manner however this is more robust and future proof (having multi-vif CSA in mind). New sdata->csa_block_tx is introduced to keep track of which interfaces requested tx to be blocked for CSA. This is required because mac80211 stops all tx queues for that purpose. This means queues must be awoken only when last tx-blocking CSA interface is finished. It is still possible to have tx queues stopped after CSA failure but as soon as offending interfaces are stopped from userspace (stop_ap or ifdown) tx queues are woken up properly.

| * mac80211: set beamforming bit in radiotapEmmanuel Grumbach2014-03-191-0/+2
| | | | | | | | | | | | | | | | | | Add a bit in rx_status.vht_flags to let the low level driver notify mac80211 about a beamformed packet. Propagate this to the radiotap header. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
| * mac80211: add status_driver_data array to ieee80211_tx_infoEliad Peller2014-03-191-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Drivers might want to have private data in addition to all other ieee80211_tx_info.status fields. The current ieee80211_tx_info.rate_driver_data overlaps with some of the non-rate data (e.g. ampdu_ack_len), so it might not be good enough. Since we already know how much free bytes remained, simply use this size to define (void *) array. While on it, change ack_signal type from int to the more explicit s32 type.

| * mac80211: allow driver to return error from sched_scan_stopJohannes Berg2014-02-201-1/+2
| | | | | | | | | | | | | | | | | | In order to solve races with sched_scan_stop, it is necessary for the driver to be able to return an error to propagate that to cfg80211 so it doesn't send an event.

| * mac80211: remove erroneous comment about RX radiotap headerJohannes Berg2014-02-131-4/+0
| | | | | | | | | | | | | | | | There's no way the driver can pre-build the radiotap header, so remove the comment stating that it can. Reported-by: Jouni Malinen <j@w1.fi> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
| * mac80211: add NAPI support backJohannes Berg2014-02-121-21/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | NAPI was originally added to mac80211 a long time ago (by John in commit 4e6cbfd09c66 in July 2010), but then removed years later (by Stanislaw in commit 30c97120c6c7 in February 2013). No driver ever used it, so that was fine. Now I'm adding support for NAPI to our driver, so add some code to mac80211 again to support NAPI. John was originally wrapping some (but not nearly all NAPI-related functions), but that doesn't scale very well with the number of functions that are there, some of which are even only inlines. Thus, instead of doing that, let the drivers manage the NAPI struct, except for napi_add() which is needed so mac80211 knows how to call napi_gro_receive(). Also remove some no longer needed definitions that were left when NAPI support was removed.

| * mac80211: reset probe_send_count also in HW_CONNECTION_MONITOR caseEliad Peller2014-02-111-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In case of beacon_loss with IEEE80211_HW_CONNECTION_MONITOR device, mac80211 probes the ap (and disconnects on timeout) but ignores the ack. If we already got an ack, there's no reason to continue disconnecting. this can help devices that supports IEEE80211_HW_CONNECTION_MONITOR only partially (e.g. take care of keep alives, but does not probe the ap. In case the device wants to disconnect without probing, it can just call ieee80211_connection_loss.

| * mac80211: propagate STBC / LDPC flags to radiotapEmmanuel Grumbach2014-02-061-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This capabilities weren't propagated to the radiotap header. We don't set here the VHT_KNOWN / MCS_HAVE flag because not all the low level drivers will know how to properly flag the frames, hence the low level driver will be in charge of setting IEEE80211_RADIOTAP_MCS_HAVE_FEC, IEEE80211_RADIOTAP_MCS_HAVE_STBC and / or IEEE80211_RADIOTAP_VHT_KNOWN_STBC according to its capabilities.
