This commit adds an option to xt_quota2 called "no-change". The effect of this option, when used, is that it will skip incrementing or decrementing the quota counter, effectively providing a quota test only. The reason for implementing this is so that I could have a rule check if quota is available for a rule in the PREROUTING tables, without actually decrementing the amount of available quota. I only wanted to decrement the amount of available quota in the FORWARD rule. Otherwise, the first packet of every connection would be counted twice.

This option adds the "quota2" match which is an advanced form of
|
|
xt_quota that also allows counting upwards, and where the counter can
|
|
be set through procfs. This allows for simple interfacing of
|
|
accounting information. It also allows for a test mode without changing
|
|
the quota value.
