commit 9c936e3f upstream. Bitwise OR/AND assignments in C aren't guaranteed to be atomic. One OGM handler might undo the set/clear of a specific bit from another handler run in between. Fix this by using the atomic set_bit()/clear_bit()/test_bit() functions. Fixes: 60432d75 ("batman-adv: Announce new capability via multicast TVLV") Signed-off-by:
