This patch does not apply, it seems your mail client has mangled the attachment. I wonder if this -Z semantics for iptables-save might be confusing. Telling this because iptables -L -z makes an atomic list and reset, so first time shows the existing counter values, so next time you call iptables -L shows zeroed counters. Probably you can use -z (lowercase) --print-zero-counters, so we reserve -Z in case we ever need something similar in the future for iptables-save that matches the exact behaviour of iptables -L -Z. Thanks.
