After digging into the code I found out where the problem is, but I don't know
how exactly should I fix it.

The fix-length buf is too small in several functions which result in buffer
overflow. Should I change the libnftnl and libmnl API to accept a length
parameter to avoid buffer overflow (which will result in a large patch), or
should I just make sure there won't be too many elements in a set?
