flow: delayed deletion of flow cache entries

2010-04-07T10:43:20+00:00

Speed up lookups by freeing flow cache entries later. After
virtualizing flow cache entry operations, the flow cache may now
end up calling policy or bundle destructor which can be slowish.

As gc_list is more effective with double linked list, the flow cache
is converted to use common hlist and list macroes where appropriate.

flow: virtualize flow cache entry methods

2010-04-07T10:43:18+00:00

This allows to validate the cached object before returning it.
It also allows to destruct object properly, if the last reference
was held in flow cache. This is also a prepartion for caching
bundles in the flow cache.

In return for virtualizing the methods, we save on:
- not having to regenerate the whole flow cache on policy removal:
  each flow matching a killed policy gets refreshed as the getter
  function notices it smartly.
- we do not have to call flow_cache_flush from policy gc, since the
  flow cache now properly deletes the object if it had any references

flow: structurize flow cache

2010-04-02T02:41:36+00:00

Group all per-cpu data to one structure instead of having many
globals. Also prepare the internals so that we can have multiple
instances of the flow cache if needed.

Only the kmem_cache is left as a global as all flow caches share
the same element size, and benefit from using a common cache.

netns xfrm: lookup in netns

2008-11-26T01:35:18+00:00

Pass netns to xfrm_lookup()/__xfrm_lookup(). For that pass netns
to flow_cache_lookup() and resolver callback.

Take it from socket or netdevice. Stub DECnet to init_net.

net: mark flow_cache_cpu_prepare() as __init

2008-11-07T07:06:44+00:00

It's called from __init code only. And__devinit in generic networking code
is pretty strange :^)

smp_call_function: get rid of the unused nonatomic/retry argument

2008-06-26T09:24:35+00:00

It's never used and the comments refer to nonatomic and retry
interchangably. So get rid of it.

net: Remove unnecessary inclusions of asm/semaphore.h

2008-04-19T02:15:50+00:00

None of these files use any of the functionality promised by
asm/semaphore.h.  It's possible that they rely on it dragging in some
unrelated header file, but I can't build all these files, so we'll have
fix any build failures as they come up.

[IPSEC] flow: reorder "struct flow_cache_entry" and remove SLAB_HWCACHE_ALIGN

2008-02-08T07:30:42+00:00

1) We can shrink sizeof(struct flow_cache_entry) by 8 bytes on 64bit arches.
2) No need to align these structures to hardware cache lines, this only waste 
   ram for very litle gain.
