[PATCH 18/28] xt_quota: report initial quota value instead of current value to userspace

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Changli Gao <xiaosuo@xxxxxxxxx>

We should copy the initial value to userspace for iptables-save and
to allow removal of specific quota rules.
