| This patch adds a new match called 'hashlimit'. |
| The idea is to have something like 'limit', but either per |
| destination-ip or per (destip,destport) tuple. |
| |
| It gives you the ability to express |
| .IP |
| '1000 packets per second for every host in 192.168.0.0/16' |
| .IP |
| '100 packets per second for every service of 192.168.1.1' |
| .P |
| with a single iptables rule. |
| .TP |
| .BI "--hashlimit " "rate" |
| A rate just like the limit match |
| .TP |
| .BI "--hashlimit-burst " "num" |
| Burst value, just like limit match |
| .TP |
| .BI "--hashlimit-mode " "dstip,srcip,dstport,srcport" |
| A comma-separated list of objects to take into consideration |
| .TP |
| .BI "--hashlimit-name " "foo" |
| The name for the /proc/net/ipt_hashlimit/foo entry |
| .TP |
| .BI "--hashlimit-htable-size " "num" |
| The number of buckets of the hash table |
| .TP |
| .BI "--hashlimit-htable-max " "num" |
| Maximum entries in the hash |
| .TP |
| .BI "--hashlimit-htable-expire " "num" |
| After how many miliseconds do hash entries expire |
| .TP |
| .BI "--hashlimit-htable-gcinterval " "num" |
| How many miliseconds between garbage collection intervals |
