      cfg80211/mac80211: Add 802.11d support · 3f2355cb
      Luis R. Rodriguez authored
      
      
      This adds country IE parsing to mac80211 and enables its usage
      within the new regulatory infrastructure in cfg80211. We parse
      the country IEs only on management beacons for the BSSID you are
      associated to and disregard the IEs when the country and environment
      (indoor, outdoor, any) matches the already processed country IE.
      
      To avoid following misinformed or outdated APs we build and use
      a regulatory domain out of the intersection between what the AP
      provides us on the country IE and what CRDA is aware is allowed
      on the same country.
      
      A secondary device is allowed to follow only the same country IE
      as it make no sense for two devices on a system to be in two
      different countries.
      
      In the case the AP is using country IEs for an incorrect country
      the user may help compliance further by setting the regulatory
      domain before or after the IE is parsed and in that case another
      intersection will be performed.
      
      CONFIG_WIRELESS_OLD_REGULATORY is supported but requires CRDA
      present.

      mac80211: remove ieee80211_notify_mac · 8e3bad65
      Johannes Berg authored
      Before ieee80211_notify_mac() was added, it was presented with the
      use case of using it to tell mac80211 that the association may
      have been lost because the firmware crashed/reset.
      
      Since then, it has also been used by iwlwifi to (slightly) speed
      up re-association after resume, a workaround around the fact that
      mac80211 has no suspend/resume handling yet. It is also not used
      by any other drivers, so clearly it cannot be necessary for "good
      enough" suspend/resume.
      
      Unfortunately, the callback suffers from a severe problem: It only
      works for station mode. If suspend/resume happens while in IBSS or
      any other mode (but station), then the callback is pointless.
      
      Recently, it has created a number of locking issues, first because
      it required rtnl locking rather than RCU due to calling sleeping
      functions within the critical section, and now because it's called
      by iwlwifi from the mac80211 workqueue that may not use the rtnl
      because it is flushed under rtnl.
      (cf. http://bugzilla.kernel.org/show_bug.cgi?id=12046
      
      )
      
      I think, therefore, that we should take a step back, remove it
      entirely for now and add the small feature it provided properly.
      For suspend and resume we will need to introduce new hooks, and for
      the case where the firmware was reset the driver will probably
      simply just pretend it has done a suspend/resume cycle to get
      mac80211 to reprogram the hardware completely, not just try to
      connect to the current AP again in station mode. When doing so, we
      will need to take into account locking issues and possibly defer
      to schedule_work from within mac80211 for the resume operation,
      while the suspend operation must be done directly.
      
      Proper suspend/resume should also not necessarily try to reconnect
      to the current AP, the time spent in suspend may have been short
      enough to not be disconnected from the AP, mac80211 will detect
      that the AP went out of range quickly if it did, and if the
      association is lost then the AP will disassoc as soon as a data
      frame is sent. We might also take into account WWOL then, and
      have mac80211 program the hardware into such a mode where it is
      available and requested.
