With all the users of the double pointers removed, this patch mops up by finally replacing all occurances of sk_buff ** in the netfilter API by sk_buff *. Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

This patch replaces unnecessary uses of skb_copy, pskb_copy and skb_realloc_headroom by functions such as skb_make_writable and pskb_expand_head. This allows us to remove the double pointers later.

Now that all callers of netfilter can guarantee that the skb is not shared, we no longer have to copy the skb in skb_make_writable. Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Due to the special location of the bridging hook, it should never see a shared packet anyway (certainly not with any in-kernel code). So it makes sense to unshare the skb there if necessary as that will greatly simplify the code below it (in particular, netfilter).

As it is we always invoke pt_prev before ing_filter, even if there are no ingress filters attached. This can cause unnecessary cloning in pt_prev. This patch changes it so that we only invoke pt_prev if there are ingress filters attached. Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Now that ip_frag always returns the packet given to it on input, we can change it to return an integer indicating error instead. This patch does that and updates all its callers accordingly.

This patch is a bit of a hack. However it is worth it if you consider that this is the only reason why we have to carry around the struct sk_buff ** pointers in netfilter. It makes ip_defrag always return the packet that was given to it on input. It does this by cloning the packet and replacing its original contents with the head fragment if necessary.

This patch creates a new function skb_morph that's just like skb_clone except that it lets user provide the spare skb that will be overwritten by the one that's to be cloned. This will be used by IP fragment reassembly so that we get back the same skb that went in last (rather than the head skb that we get now which requires us to carry around double pointers all over the place).

This patch creates a new function __copy_skb_header to merge the common code between copy_skb_header and skb_clone. Having two functions which are largely the same is a source of wasted labour as well as confusion. In fact the tc_verd stuff is almost certainly a bug since it's treated differently in skb_clone compared to the callers of copy_skb_header (skb_copy/pskb_copy/skb_copy_expand). I've kept that difference in tact with a comment added asking for clarification. Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

make sure sync wakeups preempt too - the scheduler will not overschedule as we've got various throttles against that. As a result, sync wakeups can be used more widely in the kernel (to signal wakeup affinity between tasks), and no arbitrary latencies will be introduced either.

modify account_system_time() to add cputime to cpustat->guest if we are running a VCPU. We add this cputime to cpustat->user instead of cpustat->system because this part of KVM code is in fact user code although it is executed in the kernel. We duplicate VCPU time between guest and user to allow an unmodified "top(1)" to display correct value. A modified "top(1)" is able to display good cpu user time and cpu guest time by subtracting cpu guest time from cpu user time. Update "gtime" in task_struct accordingly.
