I understand your explanation.
My problem now is to identify why the packages were dropped.
Wireshark report what listen and with ifconfig I only know how many have
been dropped.
I made a program, inline at the end, that tries to see the sockets that
I can create on a system, that will give me a idea of what protocol
handler that I have.
The program isn't complete and the options are a lot ...
Even with this I only can see the log of tcpdump and try to find frames
that belong to protocols not supported, don't know if there isn't
another reason, like Softnet backlog full or Bad / Unintended VLAN tags
Is there any way of put tcpdump or other tool to only log the packages
dropped ?
Thanks

To log such packets with tcpdump, I am afraid you'll need to patch your
kernel.
We dont have a way to tell tcpdump "sniff dropped packets"
Something like this one
(alternatively you can use dropwatch (based on drop_monitor)) and tweak
it...

The following patchset makes IPVS compatible with Patrick McHardys
IPv6 NAT patchset: http://thread.gmane.org/gmane.linux.network/239615
Specifically the part that improves defragmentation.
Patch01: Cleanup (and fixes a bug) in IPVS MTU IPv6 handling
Patch02: Extend MTU check to account for IPv6 NAT defrag changes
This patchset is based upon:
Homes ipvs-next tree:
git://git.kernel.org/pub/scm/linux/kernel/git/horms/ipvs-next.git
BUT with Patrick McHardy's IPv6 NAT patchset applied first, on top of
commit: 3654e61137db891f5312e6dd813b961484b5fdf3
title: "ipvs: add pmtu_disc option to disable IP DF for TUN packets"

Cleaning up the IPv6 MTU checking in the IPVS xmit code, by using
a common helper function __mtu_check_toobig_v6(). The MTU check
for tunnel mode is special, and does not use this helper.
Notice, this also fixes a bug, as the the MTU check in ip_vs_dr_xmit_v6()
were missing a check for skb_is_gso().
This e.g. caused issues for KVM IPVS setups, where different
Segmentation Offloading techniques are utilized, between guests,
via the virtio driver. This resulted in very bad performance,
due to the ICMPv6 "too big" messages didn't affect the sender.

mtu is already reduced with the new outer header size,
may be we can just call __mtu_check_toobig_v6 with mtu?

All other changes in patch 1 and 2 look ok and
I'll ack them next time.

Unfortunately, the way I've built the series makes it difficult to put those fixes before the re-factoring. The need for the design change drove the re-factor to give me the foundation. I'll make a note to myself to come up with something to apply to stable.

So I think there was a reason for having the type separate but I'm not
seeing that reason off the top of my head.
I think it was filesystems like gfs2 doing weird things. But I tell
you want I will play with this and if I can't reproduce find a reason
for putting them in one structure I will because there are definitely
good reasons for doing that.

Looks great--sorry I forgot to reply before. This is applied to the
ceph tree's testing branch and will go upstream for 3.7.

* [PATCH v3] net: add new QCA alx ethernet driver
From: cjren @ 2012-08-27 16:12 UTC (permalink / raw)
To: davem, netdev, linux-kernel
Cc: qca-linux-team, nic-devel, Cloud Ren, Xiong Huang,
Luis R. Rodriguez
From: Cloud Ren <cjren@qca.qualcomm.com>
This driver support two new ethernet chipsets:
1969:1091 - AR8161 Gigabit Ethernet
1969:1090 - AR8162 Fast Ethernet
1969:10A1 - AR8171 Gigabit Ethernet
1969:10A0 - AR8172 Fast Ethernet
Qualcomm Atheros(QCA) is commiting to fix all bugs found on this driver.
This driver is also permissively licensed thereby enabling developers of
other OSes to cherry pick this driver to port to their OS.
Test including build/install/uninstall/dhcp/ping/iperf/wol/reboot/etc.
is passed on the supported chipsets.
This driver and patch also have addressed all sparse and checkpatch
warnings.

* [PATCH] ipv4: Minor logic clean-up in ipv4_mtu
From: Alexander Duyck @ 2012-08-27 16:30 UTC (permalink / raw)
To: netdev; +Cc: davem, jeffrey.t.kirsher
In ipv4_mtu there is some logic where we are testing for a non-zero value
and a timer expiration, then setting the value to zero, and then testing if
the value is zero we set it to a value based on the dst. Instead of
bothering with the extra steps it is easier to just cleanup the logic so
that we set it to the dst based value if it is zero or if the timer has
expired.

Hm, I didn't see anything here that looks like bug fix. Did I miss
something? What causes the ifup/ifdown weirdness, anyhow?
(It seems hard to believe that it has something to do with the names
or locations of the various functions.)

Sorry, I wasn't very clear--I mean the bug fix I have for ifup/ifdown is in the next few patches with the implementation change I'm doing, since the code I have in place to fix it applies only to the new implementation. I'll have to make a separate patch for stable to address it there.
If the ifup/ifdown weirdness happens because we never re-enable timestamping in the hardware following reset and the device goes through a reset during an ifdown/ifup cycle. It's a pretty straightforward fix, so it shouldn't be much effort to spin up something for stable.

Thanks for your review. I am just back from my vacation.
Why not? the caller knows the cpuset changes, and pass the right NUMA
node to choose the idlest cpu from that NUMA node. Practically, the VMs
don't change the cgroups. So it will not frequency to change the
configuration.

It leaves to the caller to make the right node choice. It tries to avoid
VMs running on the same cpu but on the same node with the host to
process the guest network packets.

Based on the documentation I read before, I thought the cpus_allowed ==
cgroups control cpuset. If not, where are the cgroups control cpusets
saved?
task->cpus_allowed = tsk_cpus_allowed(task_struct *p), which is
cpumask_t.
I can change the argument from cpumask to task_struct *, and call
tsk_cpus_allowed() instead of using task->cpus_allowed.

Thinking on this use case a little further, another concern/challenge
would actually be
**creating** these VMDQ interfaces in the guest that has the VF mapped into.

* [PATCH v2] cs89x0 : packet reception not working
From: Jaccon Bastiaansen @ 2012-08-27 21:53 UTC (permalink / raw)
To: joe, davem
Cc: netdev, s.hauer, festevam, Jaccon Bastiaansen, linux-arm-kernel
The RxCFG register of the CS89x0 could be configured incorrectly
(because of misplaced parentheses), resulting in the disabling
of packet reception.

* [PATCH] userns: Add basic quota support v2
From: Eric W. Biederman @ 2012-08-28 0:12 UTC (permalink / raw)
To: Jan Kara
Cc: linux-kernel, netdev, linux-fsdevel, Serge E. Hallyn,
David Miller, Steven Whitehouse, Mark Fasheh, Joel Becker,
Ben Myers, Alex Elder, Dmitry Monakhov, Abhijith Das
In-Reply-To: <20120827085034.GA8998@quack.suse.cz>
Add the data type struct qown which holds the owning identifier of a
quota. struct qown is a replacement for the implicit union of uid,
gid and project stored in an unsigned int and the quota type field
that is was used in the quota data structures. Making the data type
explicit allows the kuid_t and kgid_t type safety to propogate more
thoroughly through the code, revealing more places where uid/gid
conversions need be made.
Allong with the data type struct qown comes the helper functions
qown_eq, qown_lt, from_qown, from_qown_munged, qown_valid, make_qown,
make_qown_invalid, make_qown_uid, make_qown_gid.
Replace struct dquot dq_id and dq_type with dq_own a struct qown.
Update the signature of dqget, quota_send_warning, dquot_get_dqblk,
and dquot_set_dqblk to use struct qown.
Make minimal changes to ext3, ext4, gfs2, ocfs2, and xfs to deal with
the change in quota structures and signatures. The ocfs2 changes are
larger than most because of the extensive tracing throughout the ocfs2
quota code that prints out dq_id.
v2:
- Renamed qown_t struct qown
- Added the quota type to struct qown.
- Removed enum quota_type (In this patch it was just noise)
- Added qown_lt, make_qown_invalid, make_qown_uid, make_qown_gid
- Taught qown to handle xfs project ids (but only in init_user_ns).
Q_XGETQUOTA calls .get_quotblk with project ids.

* jme driver: MAC spoofing issue
From: Xyne @ 2012-08-28 0:03 UTC (permalink / raw)
To: netdev
Hi,
I was directed to post the following issue to this list. I apologize if this is
not the right place for it.
I have a laptop with an onboard JMicron ethernet controller. Relevant hwinfo
output along with additional system information are included at the end of the
message.
I am able to change the MAC address using macchanger, ip and ifconfig but I am
unable to obtain an IP address via DHCP (using dhcpcd or dhclient) after doing
so.
Aside from MAC spoofing, everything else works as expected.
I have posted more information in a thread on the Arch Linux forum [1]. I have
also packaged [2] and tested the upstream Git version of the driver [3], but
the issue persists.
Does anyone have any idea of how to resolve this? I have looked at the source
code but I do not know anything about network drivers. I hope that the solution
will be readily apparent to someone who is much more familiar with the code and
drivers in general.
Any help would be appreciated.
Best regards,
Xyne

* CBQ(but probably u32 filter bug), kernel "freeze", at least from 3.2.0
From: Denys Fedoryshchenko @ 2012-08-28 4:50 UTC (permalink / raw)
To: netdev
Hi
Got information from friend, confirmed that it crashed at least two my
boxes also :)
3.0.5-rc1 is working fine, 3.4.1 , 3.2.0 from ubuntu - crashing
No watchdog fired, and didn't got yet significant debugging
information.
Very easy to reproduce:
1)run the script
2)ping 192.168.3.234
script:
DEV_OUT=eth0
ICMP="match ip protocol 1 0xff"
U32="protocol ip u32"
DST="match ip dst"
tc qdisc add dev $DEV_OUT root handle 1: cbq avpkt 1000 bandwidth
100mbit
tc class add dev $DEV_OUT parent 1: classid 1:1 cbq rate 512kbit allot
1500 prio 5 bounded isolated
tc filter add dev $DEV_OUT parent 1: prio 3 $U32 $ICMP
$DST 192.168.3.234 flowid 1:
tc qdisc add dev $DEV_OUT parent 1:1 sfq perturb 10

* [PATCH] iproute2: tc.8: update UNITS section.
From: Li Wei @ 2012-08-28 5:38 UTC (permalink / raw)
To: shemminger; +Cc: netdev, Li Wei
- rename section UNITS to PARAMETERS.
- break section PARAMETERS down to four subsections to cover the
common used parameter types(RATES, TIMES, SIZES, VALUES).
- add some explaination for IEC units in RATES.
- point out the max value we can set for RATES, TIMES and SIZES.
