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: Support a scan request for a specific BSSID

2016-04-05T08:56:28+00:00

If the cfg80211 scan trigger operation specifies a single BSSID, use that value instead of the wildcard BSSID in the Probe Request frames. Signed-off-by: Jouni Malinen Signed-off-by: Johannes Berg

mac80211: allow drivers to report CLOCK_BOOTTIME for scan results

2016-04-05T08:48:55+00:00

This was requested by Android, and the appropriate cfg80211 API had been added by Dmitry. Support it in mac80211, allowing drivers to provide the timestamp. 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: handle sched_scan_stopped vs. hw restart race

2016-01-14T10:10:20+00:00

On hw restart, mac80211 might try to reconfigure already stopped sched scan, if ieee80211_sched_scan_stopped_work() wasn't scheduled yet. This in turn will keep the device driver with scheduled scan configured, while both mac80211 and cfg80211 will clear their sched scan state once the work is scheduled. Fix it by ignoring ieee80211_sched_scan_stopped() calls while in hw restart, and flush the work before starting the reconfiguration.

mac80211: do not actively scan DFS channels

2015-12-02T21:27:53+00:00

DFS channels should not be actively scanned as we can't be sure if we are allowed or not. If the current channel is in the DFS band, active scan might be performed after CSA, but we have no guarantee about other channels, therefore it is safer to prevent active scanning at all.

mac80211: don't reconfigure sched scan in case of wowlan

2015-11-03T09:42:05+00:00

Scheduled scan has to be reconfigured only if wowlan wasn't configured, since otherwise it should continue to run (with the 'any' trigger) or be aborted. The current code will end up asking the driver to start a new scheduled scan without stopping the previous one, and leaking some memory (from the previous request.) Fix this by doing the abort/restart under the proper conditions. Signed-off-by: Eliad Peller Signed-off-by: Emmanuel Grumbach Signed-off-by: Johannes Berg

mac80211: remove PM-QoS listener

2015-10-14T16:04:08+00:00

As this API has never really seen any use and most drivers don't ever use the value derived from it, remove it. Change the only driver using it (rt2x00) to simply use the DTIM period instead of the "max sleep" time. Signed-off-by: Johannes Berg

mac80211: use new cfg80211_inform_bss_frame_data() API

2015-10-13T09:36:21+00:00

The new API is more easily extensible with a metadata struct passed to it, use it in mac80211. Signed-off-by: Johannes Berg

mac80211: convert HW flags to unsigned long bitmap

2015-06-10T14:05:36+00:00

As we're running out of hardware capability flags pretty quickly, convert them to use the regular test_bit() style unsigned long bitmaps. This introduces a number of helper functions/macros to set and to test the bits, along with new debugfs code. The occurrences of an explicit __clear_bit() are intentional, the drivers were never supposed to change their supported bits on the fly. We should investigate changing this to be a per-frame flag.
