2014-08-26netfilter: nfnetlink_acct: add filter support to nfacct counter list/resetAlexey Perevalov
You can use this to skip accounting objects when listing/resetting via NFNL_MSG_ACCT_GET/NFNL_MSG_ACCT_GET_CTRZERO messages with the NLM_F_DUMP netlink flag. The filtering covers the following cases: 1. No filter specified. In this case, the client will get old behaviour, 2. List/reset counter object only: In this case, you have to use NFACCT_F_QUOTA as mask and value 0. 3. List/reset quota objects only: You have to use NFACCT_F_QUOTA_PKTS as mask and value - the same, for byte based quota mask should be NFACCT_F_QUOTA_BYTES and value - the same. If you want to obtain the object with any quota type (ie. NFACCT_F_QUOTA_PKTS|NFACCT_F_QUOTA_BYTES), you need to perform two dump requests, one to obtain NFACCT_F_QUOTA_PKTS objects and another for NFACCT_F_QUOTA_BYTES.

2014-04-29netfilter: nfnetlink_acct: Adding quota support to accounting frameworkMathieu Poirier
nfacct objects already support accounting at the byte and packet level. As such it is a natural extension to add the possiblity to define a ceiling limit for both metrics. All the support for quotas itself is added to nfnetlink acctounting framework to stay coherent with current accounting object management. Quota limit checks are implemented in xt_nfacct filter where statistic collection is already done. Pablo Neira Ayuso has also contributed to this feature.
