Hi
I've stumbled across the issue on a heavily loaded system that uses
the nfqueue. After a few days, the number of packets wraps around:
root@xxxx ~ # cat /proc/net/netfilter/nfnetlink_queue
1 2401 1024 2 4096 247495836 0 -894731272 1
The negative value messes up the application layer statistics.
Is this a new issue or has it been fixed in recent versions?
I couldn't find anything in the changelog so I've decided not to
update libnfnetlink since it's an otherwise stable production machine
running a three year old version (0.0.39).
Second, is there a way of getting the correct value besides keeping
track of the number of wraparounds and compensating for them?
Thanks!
