xfrm: remove flow cache

2017-07-18T18:13:41Z

After rcu conversions performance degradation in forward tests isn't that noticeable anymore. See next patch for some numbers. A followup patcg could then also remove genid from the policies as we do not cache bundles anymore. Signed-off-by: Florian Westphal Signed-off-by: David S. Miller

flowcache: more "unsigned int"

2017-04-04T02:04:48Z

Make ->hash_count, ->low_watermark and ->high_watermark unsigned int and propagate unsignedness to other variables. This change doesn't change code generation because these fields aren't used in 64-bit contexts but make it anyway: these fields can't be negative numbers.

net/flowcache: Convert to hotplug state machine

2016-11-09T22:45:28Z

Install the callbacks via the state machine. Use multi state support to avoid custom list handling for the multiple instances.

flowcache: Make flow cache name space aware

2014-02-12T06:02:11Z

Inserting a entry into flowcache, or flushing flowcache should be based on per net scope. The reason to do so is flushing operation from fat netns crammed with flow entries will also making the slim netns with only a few flow cache entries go away in original implementation. Since flowcache is tightly coupled with IPsec, so it would be easier to put flow cache global parameters into xfrm namespace part. And one last thing needs to do is bumping flow cache genid, and flush flow cache should also be made in per net style. Signed-off-by: Fan Du Signed-off-by: Steffen Klassert
