Indeed, this is a kernel bug. nft uses msecs_to_jiffies which treats values <
0
as "infinity", 24d20h31m23s is 2147483000 msecs and still smaller than
INT_MAX, 1 second more causes integer overflow.
nft timeout handling also has a problem with 32bit systems, as jiffies is only
32bit. We should probably use "u64" instead of "long" and have gc task use
time_is_before_eq_jiffies64().</pre>
