      nl80211: use GFP_ATOMIC for michael mic failure message · 0f6399c4
      Bob Copeland authored
      
      
      nl80211_michael_mic_failure can be called in atomic context but
      does a GFP_KERNEL allocation.  Fixes the error below:

      cfg80211: disallow interfering with stations on non-AP (part 2) · 034d655e
      Johannes Berg authored
      
      
      On non-AP interfaces userspace has no business interfering with
      the station management, this can confuse mac80211 (and other
      drivers probably wouldn't support it anyway). Allow adding and
      removing stations only on AP interfaces.
      
      (Reconcile this w/ previous version of patch posted with same
      subject... -- JWL)

      nl80211: bounce scan request back to userspace · 362a415d
      Johannes Berg authored
      
      
      When a scan finishes only the program that asked for it
      knows what kind of scan it was; let's tell everybody else
      about the scan parameters as well so they can evaluate
      the result of the scan better. Also helps with debugging.

      cfg80211: validate AID of stations being added · 51b50fbe
      Johannes Berg authored
      
      
      We have some validation code in mac80211 but said code will
      force an invalid AID to 0 which isn't a valid AID either;
      instead require a valid AID (1-2007) to be passed in from
      userspace in cfg80211 already. Also move the code before
      the race comment since it can only be executed during STA
      addition and thus is not racy.
