      batman-adv: Use successive sequence numbers for fragments · c2f7f0e7
      Sven Eckelmann authored
      The two fragments of an unicast packet must have successive sequence numbers to
      allow the receiver side to detect matching fragments and merge them again. The
      current implementation doesn't provide that property because a sequence of two
      atomic_inc_return may be interleaved with another sequence which also changes
      the variable.
      
      The access to the fragment sequence number pool has either to be protected by
      correct locking or it has to reserve two sequence numbers in a single fetch.
      The latter one can easily be done by increasing the value of the last used
      sequence number by 2 in a single step. The generated window of two currently
      unused sequence numbers can now be scattered across the two fragments.
