* [PATCHv3 net-next-2.6 4/5] XFRM,IPv6: Add IRO remapping hook in xfrm_input()
From: Arnaud Ebalard @ 2010-09-29 9:05 UTC (permalink / raw)
To: David S. Miller, Eric Dumazet, Herbert Xu, Hideaki YOSHIFUJI; +Cc: netdev
In-Reply-To: <cover.1285749610.git.arno@natisbad.org>
Add a hook in xfrm_input() to allow IRO remapping to occur when
an incoming packet matching an existing SA (based on SPI) with
an unexpected destination or source address is received.
Because IRO does not consume additional bits in a packet (that's
the point), there is no way to demultiplex based on something
like nh or spi. Instead, IRO input handlers (for source and
destination address remapping) are called upon address mismatch
during IPsec processing.
For that to work, we rely on the fact that SPI values generated
locally are no more linked to destination address (first patch
of the set) and we postpone a bit the expected address check in
xfrm_input() (inside xfrm_state_lookup() against daddr param) by
introducing a call to the input_addr_check() handler from the
struct xfrm_state_afinfo associated with the address family.

* [PATCHv3 net-next-2.6 5/5] XFRM,IPv6: Add IRO remapping capability via socket ancillary data path
From: Arnaud Ebalard @ 2010-09-29 9:06 UTC (permalink / raw)
To: David S. Miller, Eric Dumazet, Herbert Xu, Hideaki YOSHIFUJI; +Cc: netdev
In-Reply-To: <cover.1285749610.git.arno@natisbad.org>
This provides the ability to remap src/dst address using IRO
via ancillary data passed to sockets. This is the IRO equivalent
of what is done for RH2/HAO (i.e. IPV6_RTHDR/IPV6_DSTOPTS).
This is used by UMIP during BA emission when acting as a Home
Agent.

I found following patch was enough to avoid route being created if

Yeah, something around 5-10 timers per second IIRC. There was an RFC
patch a while ago to only schedule the timer on-demand, I'll see
whether I can find it again.

* [PATCH] skge: add quirk to limit DMA
From: Stanislaw Gruszka @ 2010-09-29 9:33 UTC (permalink / raw)
To: Stephen Hemminger, netdev; +Cc: luya
Skge devices installed on some Gigabyte motherboards are not able to
perform 64 dma correctly due to board PCI implementation, so limit
DMA to 32bit if such boards are detected.
Bug was reported here:

How about the patch followed to fix this?
>What if it is called when
>some pages are already locked?
Though some pages are already locked, when the ioctl is called,
But I think it's not so critical, as we still can set the limit as wanted to
ctor->locked_pages, and check with the new limit with ctor->cur_pages.
maybe there are several pages more locked, but not too much, the rlimit
is still useful after that.
Or something I have missed here?

* New WARN from dm9000 since merge to 2.6.36-rc4
From: Jon Povey @ 2010-09-29 10:32 UTC (permalink / raw)
To: netdev@vger.kernel.org; +Cc: Kevin Hilman
Hello netdevs,
I am working on TI DaVinci DM355 (ARM) with DM9000 ethernet, booting over DHCP+NFS.
I have been working based on 2.6.34 for a while, tried merging from 2.6.36-rc4 to look at some possible USB improvements, and get a new warning on boot.
This is on a custom board, not the EVM, but uses the same ethernet design, in the same way.
As far as I can tell the board and config are the same.
Kevin reported that he has seen this same warning on different hardware.
Given that this looks like something to do with dm9000, I tried reverting the suspicious
380fefb2d "dm9000: fix "BUG: spinlock recursion""
but that made no difference.
Any clues welcome, here's the console output with some uninteresting stuff snipped.

But with this formula delay can be often rather small, or do I miss something?

Respin of the patch originally prepared by Vladislav Zolotarov.
This patch is required for the integration of Ben Hutchings bnx2x patch from
the "netif_set_real_num_{rx,tx}_queues" patch series. Since falling from MSI-X
to MSI mode due to lack of memory is broken.

* VLAN packets silently dropped in promiscuous mode
From: Roger Luethi @ 2010-09-29 11:37 UTC (permalink / raw)
To: netdev; +Cc: Patrick McHardy
I noticed packets for unknown VLANs getting silently dropped even in
promiscuous mode (this is true only for the hardware accelerated path).
netif_nit_deliver was introduced specifically to prevent that, but the
function gets called only _after_ packets from unknown VLANs have been
dropped.
Presumably this has been the case since

I'm looking for a clean solution, not a hack.

RHEL 4 and 5 have it; the first RHEL 6 beta did not but this was changed
at my request.

What would qualify as a clean solution? And is cross-platform code one
of your goals?

One where hardware access is mediated by the kernel, and doesn't involve
unloading or potentially conflicting with the driver for that hardware.

Not at this level. At the application level, yes, but we already have a
working application so I'm not interested in using flashrom for that.

This readq is for mp device to store the rx guest buffers coming from vhost.
For tx side, we don't need that, since tx buffers are sent out to device immediately.

Basically, struct page_info{} is used to store each info of the guest buffers
and some of vhost ring descriptor info according to this buffers.
struct page_ctor{} is used to manipulate multiple struct page_info{}.
Each device can do zero-copy is according one struct page_ctor{}.
Anyway, I will comments on fields of these structures.

Sorry, somehow forgot that, currently it only allocates one page a time,

This function is for debug, and so on the rq_len stuff, I'll remove them later.

That's true. Though mp_dev_change_flags() did use rtnl_lock.

The 0x38 is the size of struct page, I should use sizeof(struct page).
Let me try to fit it on 32-bit machine.

I tried that before, but performance is much worse than what I did,

It doesn't need to check about that, because for SG feature guest virtio-net
driver never submit multiple buffers for one skb. The drivers never knows
which frags belongs to which skb. The fragements are collected by multiple
buffers with numbers which a receiving skb is exactly needed.

Thanks.
It should be : if(unlikely(len < ETH_HLEN)).

flashrom can ask the kernel driver to "please stop accessing flash". No
unloading needed, no conflict in place.

I see. Just because I'm interested in how other flashing applications
solve this: Does that application work on *BSD as well? And could you
tell me the name of the app so I can take a look at it? Thanks.
