Kadlecsik József f3439dd7ee netfilter: ipset: use bitmap infrastructure completely
commit 32c72165dbd0e246e69d16a3ad348a4851afd415 upstream.

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.
