cfg80211: remove enum ieee80211_band

2016-04-12T13:56:15+00:00

This enum is already perfectly aliased to enum nl80211_band, and the only reason for it is that we get IEEE80211_NUM_BANDS out of it. There's no really good reason to not declare the number of bands in nl80211 though, so do that and remove the cfg80211 one. Signed-off-by: Johannes Berg

mac80211: add separate last_ack variable

2016-04-06T11:18:16+00:00

Instead of touching the rx_stats.last_rx from the status path, introduce and use a status_stats.last_ack variable. This will make rx_stats.last_rx indicate when the last frame was received, making it available for real "last_rx" and statistics gathering; statistics, when done per-CPU, will need to figure out which place was updated last for those items where the "last" value is exposed.

mac80211: remove rx_stats.last_rx update after sta alloc

2016-04-06T11:18:15+00:00

There's no need to update rx_stats.last_rx after allocating a station since it's already updated during allocation. Signed-off-by: Johannes Berg

mac80211: fix ibss scan parameters

2016-02-24T08:04:27+00:00

When joining IBSS a full scan should be initiated in order to search for existing cell, unless the fixed_channel parameter was set. A default channel to create the IBSS on if no cell was found is provided as well. However - a scan is initiated only on the default channel provided regardless of whether ifibss->fixed_channel is set or not, with the obvious result of the cell not joining existing IBSS cell that is on another channel.

mac80211: refactor HT/VHT to chandef code

2016-02-24T08:04:21+00:00

The station MLME and IBSS/mesh ones use entirely different code for interpreting HT and VHT operation elements. Change the code that interprets them a bit - it now modifies an existing chandef - and use it also in the MLME code. Signed-off-by: Johannes Berg

mac80211: Requeue work after scan complete for all VIF types.

2016-01-26T10:27:39+00:00

During a sw scan ieee80211_iface_work ignores work items for all vifs. However after the scan complete work is requeued only for STA, ADHOC and MESH iftypes. This occasionally results in event processing getting delayed/not processed for iftype AP when it coexists with a STA. This can result in data halt and eventually disconnection on the AP interface.

mac80211: Allow a STA to join an IBSS with 80+80 MHz channel

2015-12-04T13:43:32+00:00

While it was possible to create an IBSS with 80+80 MHz channel, joining such an IBSS resulted in falling back to 20 MHz channel with VHT disabled due to a missing switch case for 80+80. Signed-off-by: Jouni Malinen Signed-off-by: Johannes Berg

mac80211: make enable_qos parameter to ieee80211_set_wmm_default()

2015-11-03T09:55:55+00:00

The function currently determines this value, for use in bss_info.qos, based on the interface type itself. Make it a parameter instead and set it with the same logic for now. Signed-off-by: Johannes Berg

mac80211: TDLS: add proper HT-oper IE

2015-11-03T09:42:47+00:00

When 11n peers performs a TDLS connection on a legacy BSS, the HT operation IE must be specified according to IEEE802.11-2012 section 9.23.3.2. Otherwise HT-protection is compromised and the medium becomes noisy for both the TDLS and the BSS links. Signed-off-by: Arik Nemtsov Signed-off-by: Emmanuel Grumbach Signed-off-by: Johannes Berg
