    netfilter: ipset: use bitmap infrastructure completely · 32c72165
    Kadlecsik József authored Jan 19, 2020
    
    
    The bitmap allocation did not use full unsigned long sizes
    when calculating the required size and that was triggered by KASAN
    as slab-out-of-bounds read in several places. The patch fixes all
    of them.
