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.

2014-02-12mac80211: add NAPI support backJohannes Berg1-21/+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.

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.

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.

2014-02-04mac80211: remove module handling from rate control opsJohannes Berg1-1/+0

2014-02-04mac80211: only set CSA beacon when at least one beacon must be transmittedLuciano Coelho1-4/+6
A beacon should never have a Channel Switch Announcement information element with a count of 0, because a count of 1 means switch just before the next beacon. So, if a count of 0 was valid in a beacon, it would have been transmitted in the next channel already, which is useless. A CSA count equal to zero is only meaningful in action frames or probe_responses. Fix the ieee80211_csa_is_complete() and ieee80211_update_csa() functions accordingly. With a CSA count of 0, we won't transmit any CSA beacons, because the switch will happen before the next TBTT. To avoid extra work and potential confusion in the drivers, complete the CSA immediately, instead of waiting for the driver to call ieee80211_csa_finish(). To keep things simpler, we also switch immediately when the CSA count is 1, while in theory we should delay the switch until just before the next TBTT. Additionally, move the ieee80211_csa_finish() function to cfg.c, where it makes more sense.

2014-01-10mac80211: handle MMPDUs at EOSP correctlyJohannes Berg1-0/+5
If a uAPSD service period ends with an MMPDU, we currently just send that MMPDU, but it obviously won't get the EOSP bit set as it doesn't have a QoS header. This contradicts the standard, so add a QoS-nulldata frame after the MMPDU to properly terminate the service period with a frame that has EOSP set. Also fix a bug wrt. the TID for the MMPDU, it shouldn't be set to 0 unconditionally but use the actual TID that was assigned. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2013-12-16mac80211: add pre-RCU-sync sta removal driver operationJohannes Berg1-2/+19
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.

It's *NOT* intended to be used for any normal/generic feature or any optimisations that could be implemented across drivers. Currently, only vendor commands (with replies) are supported, no dump operations or vendor-specific notifications.

Add a new field to ieee80211_chanctx_conf to indicate the min required channel configuration. Tuning to a narrower channel might help reducing the noise level and saving some power. The min required channel definition is the max of all min required channel definitions of the interfaces bound to this channel context. In AP mode, use 20MHz when there are no connected station. When a new station is added/removed, calculate the new max bandwidth supported by any of the stations (e.g. 80MHz when 80MHz and 40MHz stations are connected). In other cases, simply use bss_conf.chandef as the min required chandef. Notify drivers about changes to this field by calling drv_change_chanctx with a new CHANGE_MIN_WIDTH notification.

2013-10-01mac80211: support reporting A-MSDU subframes individuallyMichal Kazior1-0/+10
Some devices may not be able to report A-MSDUs in single buffers. Drivers for such devices were forced to re-assemble A-MSDUs which would then be eventually disassembled by mac80211. This could lead to CPU cache thrashing and poor performance. Since A-MSDU has a single sequence number all subframes share it. This was in conflict with retransmission/duplication recovery (IEEE802.11-2012: 9.3.2.10). Patch introduces a new flag that is meant to be set for all individually reported A-MSDU subframes except the last one. This ensures the last_seq_ctrl is updated after the last subframe is processed. If an A-MSDU is actually a duplicate transmission all reported subframes will be properly discarded.

2013-09-26mac80211: add ieee80211_iterate_active_interfaces_rtnl()Johannes Berg1-0/+19
If it is needed to disconnect multiple virtual interfaces after (WoWLAN-) suspend, the most obvious approach would be to iterate all interfaces by calling ieee80211_iterate_active_interfaces() and then call ieee80211_resume_disconnect() for each one. This is what the iwlmvm driver does. Unfortunately, this causes a locking dependency from mac80211's iflist_mtx to the key_mtx. This is problematic as the former is intentionally never held while calling any driver operation to allow drivers to iterate with their own locks held. The key_mtx is held while installing a key into the driver though, so this new lock dependency means drivers implementing the logic above can no longer hold their own lock while iterating. To fix this, add a new ieee80211_iterate_active_interfaces_rtnl() function that iterates while the RTNL is already held. This is true during suspend/resume, so that then the locking dependency isn't introduced. While at it, also refactor the various interface iterators and keep only a single implementation called by the various cases. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2013-08-16mac80211: add APIs to allow keeping connections after WoWLANJohannes Berg1-0/+83
In order to be able to (securely) keep connections alive after the system was suspended for WoWLAN, we need some additional APIs. We already have API (ieee80211_gtk_rekey_notify) to tell wpa_supplicant about the new replay counter if GTK rekeying was done by the device while the host was asleep, but that's not sufficient. If GTK rekeying wasn't done, we need to tell the host about sequence counters for the GTK (and PTK regardless of rekeying) that was used while asleep, add ieee80211_set_key_rx_seq() for that. If GTK rekeying was done, then we need to be able to disable the old keys (with ieee80211_remove_key()) and allocate the new GTK key(s) in mac80211 (with ieee80211_gtk_rekey_add()). If protocol offload (e.g. ARP) is implemented, then also the TX sequence counter for the PTK must be updated, using the new ieee80211_set_key_tx_seq() function.
