This will not apply to recent kernels, drivers/net/usb/asix.c has been
split into several files, please make these changes in

* [PATCH 2/4] ipv6: unify conntrack reassembly expire code with standard one
From: Cong Wang @ 2012-09-18 4:29 UTC (permalink / raw)
To: netdev
Cc: netfilter-devel, Cong Wang, Herbert Xu, Michal Kubeček,

In-Reply-To: <1347942582-23962-1-git-send-email-amwang@redhat.com>
Two years ago, Shan Wei tried to fix this:
http://patchwork.ozlabs.org/patch/43905/
The problem is that RFC2460 requires an ICMP Time
Exceeded -- Fragment Reassembly Time Exceeded message should be
sent to the source of that fragment, if the defragmentation
times out.
"
If insufficient fragments are received to complete reassembly of a
packet within 60 seconds of the reception of the first-arriving
fragment of that packet, reassembly of that packet must be
abandoned and all the fragments that have been received for that
packet must be discarded. If the first fragment (i.e., the one
with a Fragment Offset of zero) has been received, an ICMP Time
Exceeded -- Fragment Reassembly Time Exceeded message should be
sent to the source of that fragment.
"
As Herbert suggested, we could actually use the standard IPv6
reassembly code which follows RFC2460.
With this patch applied, I can see ICMP Time Exceeded sent
from the receiver when the sender sent out 3/4 fragmented
IPv6 UPD packet.

As pointed by Michal, it is necessary to add a new
namespace for nf_conntrack_reasm code, this prepares
for the second patch.

you think they are in good shape now?
Thanks,

That is true. I hadn't thought about anything other than SLAB/SLUB.
It also just occurred to me that there might be some benefit in cache
aligning the max header size. It seems like doing something like that
should reduce the overall memory footprint and would probably improve
performance.
Thanks,

Yeah, actually net->ipv6 is also defined with #if
IS_ENABLED(CONFIG_IPV6), so IS_ENABLED() is the right fix.

I know it's not on many people's radar, but with SLOB it will happen
a lot probably.

Sorry I misspoke. What I meant to say is that the allocation will be
aligned to a slab size. If you take a look at alloc_skb it looks like
it is still using __alloc_skb so it is going to add skb_shared_info to
the size so at least in the case of most 64 bit systems the total
allocation size is going to be larger than 512 and as a result skb->head
will be allocated from a 1K slab cache leaving plenty of room for
padding to be added later. On 32 bit systems the total size will likely
be a little over 256 and get rounded up to 512.
The only real thing that bugged me about this is that you were adding 64
when the most you should ever need is 10. That was the only real reason
I felt like commenting on it.

That is true, but the fact is there is probably a fair amount of that
going on without people even realizing it. As I recall the smallest skb
head you can allocate on a 64 bit system currently is something like
128 bytes which comes from the 512 byte slab, the next step up after
that is a 640 byte head. Since MAX_TCP_HEADER starts at 160 the
likelihood of it not getting at least 16 bytes of padding is pretty low.

Or, alternatively, use IS_ENABLED() or a similar test which will take

Ah... then this should be the cause of your build failure, as I always
compile IPV6 as builtin.
Sorry for this, my bad. I will remove this #ifdef and resend the whole

There is no change for net/ipv6/proc.c, ip6_frag_nqueues() and
ip6_frag_mem() are now defined as static inline in include/net/ipv6.h
which is already #included by net/ipv6/proc.c. This is why I still don't
see how that build error could happen.
Actually, the #ifdef CONFIG_IPV6 is not needed at all, as
sockstat6_seq_show() is their only caller, which is compiled only when
CONFIG_IPV6 is enabled.
Thanks.

Yes, this could be a problem, putting a hold on the sk would be overkill for the

From: Eric Dumazet <edumazet@google.com>
Stephan Springl found that commit 1402d366019fed "tcp: introduce
tcp_try_coalesce" introduced a regression for rlogin
It turns out problem comes from TCP urgent data handling and
a change in behavior in input path.
rlogin sends two one-byte packets with URG ptr set, and when next data
frame is coalesced, we lack sk_data_ready() calls to wakeup consumer.

* Re: NIC emulation with built-in rate limiting?
From: Rick Jones @ 2012-09-17 21:48 UTC (permalink / raw)
To: Gregory Carter; +Cc: netdev, kvm, Lee Schermerhorn, Brian Haley
In-Reply-To: <504F8B96.7070302@aesgi.com>
So, while the question includes the "stability" of how things get
plumbed for a VM and whether moving some of that into the NIC emulation
might help :) I've gone ahead and re-run the experiment with bare-iron.
This time just for kicks I used 50 Mbit/s throttle inbound and
outbound. The results can be seen in:
ftp://ftp.netperf.org/50_mbits.tgz
Since this is now bare-iron, inbound is ingress and outbound is egress.
That is reversed from what it would be for a VM situation where VM
outbound traverses the ingress filter and VM inbound traverses the
egress qdisc.
Both systems were running Ubuntu 12.04.01 3.2.0-26 kernels, there was
plenty of CPU horsepower (2x E5-2680s in this case) and the network
between them was 10GbE using their 530FLB LOMs (BCM 57810S) connected
via a ProCurve 6120 10GbE switch. That simply happened to be the most
convenient bare-iron hardware I had on hand as one of the cobbler's
children. There was no X running on the systems, the only thing of note
running on them was netperf.
So, is the comparative instability between inbound and outbound
fundamentally inherent in using ingress policing, or more a matter of
"Silly Rick, you should be using <these settings> instead?"
If the former, is it then worthwhile to try to have NIC emulation only
pull from the VM at the emulated rate, to keep the queues in the VM
where it can react to them more directly? And are there any NIC
emulations doing that already (as virtio does not seem to at present)?
happy benchmarking,
rick jones

Subject: [PATCH 00/15] Add new driver RTL8723AE
Date: Mon, 17 Sep 2012 16:21:58 -0500

X-Mailer: git-send-email 1.7.10.4
X-Mailer: git-send-email 1.7.10.4
From: Larry Finger <Larry.Finger@lwfinger.net>
This set of patches add the new driver rtl8723ae to the rtlwifi family
of drivers. It handles the RTL8723AE, which is now being included in
some Toshiba laptops. This driver is derived from version 0007.0809.2012
of the vendor driver.
Depending on how long the review process takes, I am hoping to include
this driver in kernel 3.7.
