Bug description:
On a server under Ubuntu 12.04 I automatically update firewall rules and I
unfortunately noticed that if 2 rules are processed at the same time it leads
to an inconsistent result between iptables and ufw status.
In fact it can be reproduced using the python script in attachment.
Before executing this script I didn't have any rules matching the ip
192.168.254.1 on my computer.
After a launch iptables takes into acount 464 rules.
sudo iptables -L -n | grep 192.168.254.1 | wc -l
464
It should be 500 rules but the script stressed a lot my system and all rules
can't be processed by iptables
sudo ./test_ufw_threads.py
iptables: Resource temporarily unavailable.
iptables: Resource temporarily unavailable.
iptables: Resource temporarily unavailable.
[...]
Anyway, ufw stores only the last updates (in /lib/ufw/user.rules):
sudo ufw status

192.168.254.1 1234/tcp ALLOW 192.168.43.10
So I can't delete other rules using ufw, I had to directly use iptables.
In this case I can only delete 10 rules using ufw.
Could you please handle some kind of lock?
