* [PATCH] add schedule_on_each_cpu()Christoph Lameter2006-01-082-0/+20
| | | | | | | | | | | | | | | | | | | swap migration's isolate_lru_page() currently uses an IPI to notify other processors that the lru caches need to be drained if the page cannot be found on the LRU. The IPI interrupt may interrupt a processor that is just processing lru requests and cause a race condition. This patch introduces a new function run_on_each_cpu() that uses the keventd() to run the LRU draining on each processor. Processors disable preemption when dealing the LRU caches (these are per processor) and thus executing LRU draining from another process is safe. Thanks to Lee Schermerhorn <lee.schermerhorn@hp.com> for finding this race condition.

* [PATCH] mm: free_pages optNick Piggin2006-01-081-28/+30
| | | | | | | | | | | | | | | Try to streamline free_pages_bulk by ensuring callers don't pass in a 'count' that exceeds the list size. Some cleanups: Rename __free_pages_bulk to __free_one_page. Put the page list manipulation from __free_pages_ok into free_one_page. Make __free_pages_ok static.

* [PATCH] mm: cleanup zone_pcpNick Piggin2006-01-081-8/+8
| | | | | | | | | | | | | Use zone_pcp everywhere even though NUMA code "knows" the internal details of the zone. Stop other people trying to copy, and it looks nicer. Also, only print the pagesets of online cpus in zoneinfo.

* [PATCH] Make high and batch sizes of per_cpu_pagelists configurableRohit Seth2006-01-085-0/+81
| | | | | | | | | | | | | | | | | | | As recently there has been lot of traffic on the right values for batch and high water marks for per_cpu_pagelists. This patch makes these two variables configurable through /proc interface. A new tunable /proc/sys/vm/percpu_pagelist_fraction is added. This entry controls the fraction of pages at most in each zone that are allocated for each per cpu page list. The min value for this is 8. It means that we don't allow more than 1/8th of pages in each zone to be allocated in any single per_cpu_pagelist. The batch value of each per cpu pagelist is also updated as a result. It is set to pcp->high/4. The upper limit of batch is (PAGE_SHIFT * 8) Signed-off-by: Rohit Seth <rohit.seth@intel.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] drop-pagecacheAndrew Morton2006-01-089-5/+107
| | | | | | | | | | | | | | | | | | | | | | Add /proc/sys/vm/drop_caches. When written to, this will cause the kernel to discard as much pagecache and/or reclaimable slab objects as it can. THis operation requires root permissions. It won't drop dirty data, so the user should run `sync' first. Caveats: a) Holds inode_lock for exorbitant amounts of time. b) Needs to be taught about NUMA nodes: propagate these all the way through so the discarding can be controlled on a per-node basis. This is a debugging feature: useful for getting consistent results between filesystem benchmarks. We could possibly put it under a config option, but it's less than 300 bytes.

* [NETFILTER]: Redo policy lookups after NAT when neccessaryPatrick McHardy2006-01-074-3/+32
| | | | | | | | | | When NAT changes the key used for the xfrm lookup it needs to be done again.

* [NETFILTER]: Fix xfrm lookup in ip_route_me_harder/ip6_route_me_harderPatrick McHardy2006-01-0711-12/+34
| | | | | | | | | | | | | | | | | ip_route_me_harder doesn't use the port numbers of the xfrm lookup and uses ip_route_input for non-local addresses which doesn't do a xfrm lookup, ip6_route_me_harder doesn't do a xfrm lookup at all. Use xfrm_decode_session and do the lookup manually, make sure both only do the lookup if the packet hasn't been transformed already. Makeing sure the lookup only happens once needs a new field in the IP6CB, which exceeds the size of skb->cb. The size of skb->cb is increased to 48b. Apparently the IPv6 mobile extensions need some more room anyway. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | When the innermost transform uses transport mode the decapsulated packet is not visible to netfilter.

* [XFRM]: Netfilter IPsec output hooksPatrick McHardy2006-01-074-70/+148
| | | | | | | | | | | | | | | | | | | | Call netfilter hooks before IPsec transforms. Packets visit the FORWARD/LOCAL_OUT and POST_ROUTING hook before the first encapsulation and the LOCAL_OUT and POST_ROUTING hook before each following tunnel mode transform. Patch from Herbert Xu <herbert@gondor.apana.org.au>: Move the loop from dst_output into xfrm4_output/xfrm6_output since they're the only ones who need to it. xfrm{4,6}_output_one() processes the first SA all subsequent transport mode SAs and is called in a loop that calls the netfilter hooks between each two calls. In order to avoid the tail call issue, I've added the inline function nf_hook which is nf_hook_slow plus the empty list check. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.
