      mac80211: rename files · 2c8dccc7
      Johannes Berg authored
      
      
      This patch renames all mac80211 files (except ieee80211_i.h) to get rid
      of the useless ieee80211_ prefix.

      mac80211: fix key vs. sta locking problems · 3b96766f
      Johannes Berg authored
      
      
      Up to now, key manipulation is supposed to run under RTNL to
      avoid concurrent manipulations and also allow the set_key()
      hardware callback to sleep. This is not feasible because STA
      structs are rcu-protected and thus a lot of operations there
      cannot take the RTNL. Also, key references are rcu-protected
      so we cannot do things atomically.
      
      This patch changes key locking completely:
       * key operations are now atomic
       * hardware crypto offload is enabled and disabled from
         a workqueue, due to that key freeing is also delayed
       * debugfs code is also run from a workqueue
       * keys reference STAs (and vice versa!) so during STA
         unlink the STAs key reference is removed but not the
         keys STA reference, to avoid races key todo work is
         run before STA destruction.
       * fewer STA operations now need the RTNL which was
         required due to key operations
      
      This fixes the locking problems lockdep pointed out and also
      makes things more light-weight because the rtnl isn't required
      as much.
      
      Note that the key todo lock/key mutex are global locks, this
      is not required, of course, they could be per-hardware instead.
