* linux-next: manual merge of the kvm tree with the tree
From: Stephen Rothwell @ 2013-03-25 2:32 UTC (permalink / raw)

[-- Attachment #1: Type: text/plain, Size: 1066 bytes --]
Hi all,
Today's linux-next merge of the kvm tree got a conflict in
drivers/s390/kvm/virtio_ccw.c between commit 9d0ca6ed6f2f ("virtio:
remove obsolete virtqueue_get_queue_index()") from the net-next tree and
commit 07e169335ff0 ("virtio_ccw: pass a cookie value to kvm hypercall")
from the kvm tree.
I fixed it up (see below) and can carry the fix as necessary (no action
is required).

Cheers,

* [PATCH net-next] netfilter: implement RFC3168 5.3 (ecn protection) for ipv6 fragmentation handling
From: Hannes Frederic Sowa @ 2013-03-25 1:20 UTC (permalink / raw)
To: netfilter-devel; +Cc: eric.dumazet, jbrouer, yoshfuji, netdev
This change brings netfilter reassembly logic on par with
reassembly.c. The corresponding change in net-next is
eec2e6185ff6eab18c2cae9b01a9fbc5c33248fc.

I duplicated ip6_frag_ecn here again because I could not find a good header to
stick it in. There is a recursive header inclusion if I include inet_ecn.h
from inet_frag.h. I hope this is ok for the time being.

Under what conditions can entries be removed or added to
these RB-trees without the RTNL being held?
If such events cannot happen, then no locking is needed.
Even if your change is correct and necessary, the answer to my
needs to be added to your commit message.

I'm disappointed that you have enough energy to point out such a lower
priority omission, but you lack the time for something more important,
which is giving this patch your explicit ACK if it fixes all of the
issues you pointed out to him.

The problem on ARM (and probably on powerpc, and on something called
"metag" - grep -r 'coherent DMA mask is unset' arch) is that the default
coherent DMA mask is zero. IOW, coherent DMA allocations are, by
default, disabled. A driver has to dma_set_coherent_mask() or, as many
drivers do, set dev->coherent_dma_mask directly (IMHO
dev->coherent_dma_mask along with dev->dma_mask are private DMA API
stuff and e.g. device drivers have no interest there).
The zero default is IMHO, WRT the actual DMA API, an ARM bug (and
powerpc's etc). Nevertheless, the patch I posted does everything as
required by the API. Specifically, the IXP4xx arch part makes
IXP4xx's dma_set_coherent_mask() compliant with DMA API, and the actual
dma_set_coherent_mask() calls in drivers are both valid and I guess
recommended by the API.
The patch doesn't touch the core ARM issue, that's right.

We should do this increment for all protocols when DF is set,
not just TCP.
