Hi Patrick & Simon
Please drop this patch / pull request.
I need to take a way 2 rows,
I.e. the new feature that disables ipvs when last service is removed,
it doesn't work since it's not the last service.

Thanks, will do that later - just prepared a patch
https://lists.open-mesh.org/pipermail/b.a.t.m.a.n/2011-May/004562.html but
currently have no time to make a final version (maybe in 8 hours) and send it

Thanks,

Being more precise about accounting how memory was used in the memory
subsystem rather than the network subsystem didn't seem totally
unreasonable.

nr_objects_per_slab-1 pages should be the upper bound. i.e. the most
objects that can fit in a partial slab that is managing packets. The
exact value would depend on whether SLUB is used (high order pages) and
what the page size is.

I see the point of your concerns and I'll investigate closer if propagating
the pfmemalloc flag to the socket if the page was allocated from reserves
both makes sense and works as expected.

We can't prevent incoming packets and we do not know at allocation
time if the packet can be dropped so there are limited throttling
options there.

Do the devices in question use cdc_ether?
The problem I see with this patch is that cdc_ether uses .reset_resume = usbnet_resume
Therefore the device will not have been reset from the viewpoint of the device, yet
the device may be open, so the bug would strike again.
It seems to me that this patch is not wrong as such, but incomplete.
Regards
Oliver

* [PATCH 1/2] IPVS: Change of socket usage to enable name space exit.

From: Hans Schillstrom <hans@schillstrom.com>
If the sync daemons run in a name space while it crashes
or get killed, there is no way to stop them except for a reboot.
When all patches are there, ip_vs_core will handle register_pernet_(),
i.e. ip_vs_sync_init() and ip_vs_sync_cleanup() will be removed.
Kernel threads should not increment the use count of a socket.
By calling sk_change_net() after creating a socket this is avoided.
sock_release cant be used intead sk_release_kernel() should be used.
Thanks Eric W Biederman for your advices.
This patch is based on net-next-2.6 ver 2.6.39-rc2

From: Hans Schillstrom <hans@schillstrom.com>
This patch tries to restore the initial init and cleanup
sequences that was before namspace patch.
The number of calls to register_pernet_device have been
reduced to one for the ip_vs.ko
Schedulers still have their own calls.
This patch adds a function __ip_vs_service_cleanup()
and a throttle or actually on/off switch for
the netfilter hooks.
The nf hooks will be enabled when the first service is loaded
and disabled when the last service is removed or when a
namespace exit starts.

* [GIT PULL nf-2.6] IPVS (Take II)
From: Simon Horman @ 2011-05-03 7:05 UTC (permalink / raw)
To: lvs-devel, netdev, netfilter-devel, netfilter
Cc: Wensong Zhang, Julian Anastasov, Patrick McHardy,
Hans Schillstrom, Hans Schillstrom, Eric W. Biederman
Hi Patrick,
please consider pulling
git://git.kernel.org/pub/scm/linux/kernel/git/horms/ipvs-2.6.git for-patrick
to get the following fix from Hans. They resolve some problems related
to his netns for IPVS work which was incorporated into 2.6.39-rc1.
The pull request is based on nf-2.6/master.
There are other less-pressing changes from Hans which
I plan to get you to pull into nf-next-2.6 once these
changes make it there (presumably via net-2.6 and then net-next-2.6).
Hans Schillstrom (2):
IPVS: Change of socket usage to enable name space exit.
IPVS: init and cleanup restructuring.

* [PATCH] net: Add sendmmsg socket system call
From: Anton Blanchard @ 2011-05-03 6:21 UTC (permalink / raw)
To: acme; +Cc: netdev
This patch adds a multiple message send syscall and is the send
version of the existing recvmmsg syscall. This is heavily
based on the patch by Arnaldo that added recvmmsg.
I wrote a microbenchmark to test the performance gains of using
this new syscall:
http://ozlabs.org/~anton/junkcode/sendmmsg_test.c
The test was run on a ppc64 box with a 10 Gbit network card. The
benchmark can send both UDP and RAW ethernet packets.
64B UDP
# sendmmsg_test -u 192.168.1.2 12345 64 <batch>
batch pkts/sec
1 804570
2 872800 (+ 8 %)
4 916556 (+14 %)
8 939712 (+17 %)
16 952688 (+18 %)
32 956448 (+19 %)
64 964800 (+20 %)
64B raw socket
# sendmmsg_test -r eth1 64 <batch>
batch pkts/sec
1 1201449
2 1350028 (+12 %)
4 1461416 (+22 %)
8 1513080 (+26 %)
16 1541216 (+28 %)
32 1553440 (+29 %)
64 1557888 (+30 %)
We see a 20% improvement in throughput on UDP send and 30%
on raw socket send.

* [PATCH V2] net/stmmac: Move "#include <linux/platform_device.h>" to linux/stmmac.h
From: Viresh Kumar @ 2011-05-03 4:36 UTC (permalink / raw)
To: peppe.cavallaro, davem

stmmac.h uses struct platform_device and doesn't include
<linux/platform_device.h>. Whereas drivers/net/stmmac/stmmac.h includes it, but
doesn't directly use it. And so we get following compilation warning while using
this file:
warning: ‘struct platform_device’ declared inside parameter list
This patch includes <linux/platform_device.h> in linux/stmmac.h and removes it
from drivers/net/stmmac/stmmac.h

* linux-next: manual merge of the rcu tree with the net tree
From: Stephen Rothwell @ 2011-05-03 4:24 UTC (permalink / raw)
To: Paul E. McKenney
Cc: linux-next, linux-kernel, Eric Dumazet, David Miller, netdev
Hi Paul,
Today's linux-next merge of the rcu tree got a conflict in
net/core/filter.c between commit 0a14842f5a3c ("net: filter: Just In Time
compiler for x86-64") from the net tree and commit 10cde158c259
("net,rcu: convert call_rcu(sk_filter_release_rcu) to kfree_rcu") from
the rcu tree.
The former adds another operation into sk_filter_release_rcu(), so I have
effectively reverted the rcu tree change for now (by applying the patch
below as a merge fixup).

I must have missed that (or missed its implications), sorry.

ah, there it is ... I obviously didn't read it well enough or notice the

Do you automatically generate these emails? :-)
I CC:'d you on an email earlier about this conflict, in an effort to
let you know I anticipated it and you therefore didn't need to notify

Hi all,
Today's linux-next merge of the net tree got a conflict in
drivers/net/tg3.c between commit 6fdbab9d93e0 ("tg3: Fix failure to
enable WoL by default when possible") from the net-current tree and
commit 63c3a66fe6c8 ("tg3: Convert u32 flag,flg2,flg3 uses to bitmap")
from the net tree.
Context changes. I fixed it up (see below) and can carry the fix as
necessary.

The config file is attached. It's for the 2.6.38-gentoo-r3 kernel, which
is based on 2.6.38.4.
