This sentence is misleading, as rtnl is a mutex.
Its legal to sleep while holding it
So the atomic context is because of lock #1, not 'lock' #2

I think we should use static_key_false() here, as netpoll is an
"unlikely" code path.
Using static branch is a good idea though.

This patch uses mdelay instead.

* [net-next 3/4] ixgbevf: Add support for VF API negotiation
From: Jeff Kirsher @ 2012-09-19 4:31 UTC (permalink / raw)
To: davem; +Cc: Alexander Duyck, netdev, gospo, sassmann, Jeff Kirsher
In-Reply-To: <1348029108-26659-1-git-send-email-jeffrey.t.kirsher@intel.com>
From: Alexander Duyck <alexander.h.duyck@intel.com>
This change makes it so that the VF can support the PF/VF API negotiation
protocol. Specifically in this case we are adding support for API 1.0
which will mean that the VF is capable of cleaning up buffers that span
multiple descriptors without triggering an error.

Current implementation enables EEE on only i350 device. This patch enables
EEE on all eee_supported devices. Also, configured LPI clock to keep
running before EEE is enabled on i210 and i211 devices.

* [net-next 1/4] igb: Remove artificial restriction on RQDPC stat reading
From: Jeff Kirsher @ 2012-09-19 4:31 UTC (permalink / raw)
To: davem; +Cc: Alexander Duyck, netdev, gospo, sassmann, Jeff Kirsher
In-Reply-To: <1348029108-26659-1-git-send-email-jeffrey.t.kirsher@intel.com>
From: Alexander Duyck <alexander.h.duyck@intel.com>
For some reason the reading of the RQDPC register was being artificially
limited to 4K. Instead of limiting the value we should read the value and
add the full amount. Otherwise this can lead to a misleading number of
dropped packets when the actual value is in fact much higher.

* [ethtool] ethtool: --set-eee sends ETHTOOL_SEEE ioctl even if nothing changed
From: Jeff Kirsher @ 2012-09-19 3:20 UTC (permalink / raw)
To: bhutchings; +Cc: Bruce Allan, netdev, gospo, sassmann, Jeff Kirsher
From: Bruce Allan <bruce.w.allan@intel.com>
When setting EEE parameters with the --set-eee command line option,
ethtool will send the ETHTOOL_SEEE ioctl down to the driver even if
none of the provided parameters are a change from current settings.
Simply ignore it when that happens as done with other ethtool commands.

* [PATCH 2/4] ipv6: unify conntrack reassembly expire code with standard one
From: Cong Wang @ 2012-09-19 2:50 UTC (permalink / raw)
To: netdev
Cc: netfilter-devel, Cong Wang, Herbert Xu, Michal Kubeček,
David Miller, Hideaki YOSHIFUJI, Patrick McHardy,
Pablo Neira Ayuso
In-Reply-To: <1348023011-16195-1-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.

* [PATCH 1/4] ipv6: add a new namespace for nf_conntrack_reasm
From: Cong Wang @ 2012-09-19 2:50 UTC (permalink / raw)
To: netdev
Cc: netfilter-devel, Cong Wang, Herbert Xu, Michal Kubeček,
David Miller, Patrick McHardy, Pablo Neira Ayuso
In-Reply-To: <1348023011-16195-1-git-send-email-amwang@redhat.com>
As pointed by Michal, it is necessary to add a new
namespace for nf_conntrack_reasm code, this prepares
for the second patch.

That will work too. (I briefly thought about this but was distracted by

Having gone to such great lengths to avoid ooo for RFS, I don't think
DaveM would be happy if we allow it for virtio_net.
So, how *would* we implement such a thing for a "hardware" device? What
if the device will only change the receive queue if the old receive
queue is empty?

* [PATCH] net: do not disable sg for AoE
From: Ed Cashin @ 2012-09-19 0:20 UTC (permalink / raw)
To: davem; +Cc: ecashin, akpm, jesse, netdev, linux-kernel
A change in a series of VLAN-related changes appears to have
inadvertently disabled the use of the scatter gather feature of
network cards for transmission of non-IP ethernet protocols like ATA
over Ethernet (AoE). Below is a reference to the commit that
introduces a "harmonize_features" function that turns off scatter
gather when the NIC does not support hardware checksumming for the
ethernet protocol of an sk buff.
commit f01a5236bd4b140198fbcc550f085e8361fd73fa
Author: Jesse Gross <jesse@nicira.com>
Date: Sun Jan 9 06:23:31 2011 +0000
net offloading: Generalize netif_get_vlan_features().
The can_checksum_protocol function is not equipped to consider a
protocol that does not require checksumming. Calling it for a
protocol that requires no checksum is inappropriate.
The patch below has harmonize_features call can_checksum_protocol when
the protocol needs a checksum, so that the network layer is not forced
to perform unnecessary skb linearization on the transmission of AoE
packets. Unnecessary linearization results in decreased performance
and increased memory pressure, as reported here:
http://www.spinics.net/lists/linux-mm/msg15184.html
The problem has probably not been widely experienced yet, because
only recently has the kernel.org-distributed aoe driver acquired the
ability to use payloads of over a page in size, with the patchset
recently included in the mm tree:
https://lkml.org/lkml/2012/8/28/140
The coraid.com-distributed aoe driver already could use payloads of
greater than a page in size, but its users generally do not use the
newest kernels.

Why not moving the TCP-code out of inet_sock_destruct by modifying the sk_destruct
callback when TFO is in use? Like the below (only compile-tested) patch. That
way inet_sock_destruct stays TFO-free.

This bug was introduced as part of patch
7ab4551f3b391818e29263279031dca1e26417c6
It turns out the call "socket(PF_INET/PF_INET6, SOCK_RAW, IPPROTO_TCP)"
will cause a raw socket to be created with protocol == IPPROTO_TCP
so checking against the protocol field in sk alone is not sufficient
to guarantee a TCP socket. One must also check type == SOCK_STREAM.

The driver does not do much work in its irq handler. You may as well
convert it to the usual tg3-ish locking style (i.e. almost no locking).

* Re: BUG: TCPDUMP invalid cksum persists after disabling TCP cksum offload
From: Jamie Gloudon @ 2012-09-18 22:20 UTC (permalink / raw)

Rick is correct. Disabling TX CKO also disable TSO. You can see that in
my ethtool output.
