* expr: limit: operational limit matchPhil Oester2013-10-221-2/+2
| | | | | | | | | | | | | | | | | | | | | The nft limit match currently does not work at all. Below patches to nftables, libnftables, and kernel address the issue. A few notes on the implementation: - Removed support for nano/micro/milli second limits. These seem pointless, given we are using jiffies in the limit match, not a hpet. And who really needs to limit items down to sub-second level?? - 'depth' member is removed as unnecessary. All we need in the kernel is the rate and the unit. - 'stamp' member becomes the time we need to next refresh the token bucket, instead of being updated on every packet which goes through the match. This closes netfilter bugzilla #827, reported by Eric Leblond. Signed-off-by: Phil Oester <kernel@linuxace.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

* examples: table: add example of dormant tablesPablo Neira Ayuso2012-11-111-0/+9
| | | | | | | | Now we add a non-dormant table which is not active. We can add chains and rules to it that would not have any effect. Once we change the flag to wake it up, the rule-set becomes active. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
