* [2/6] vxge: fix pktgen hangs (don't abuse skb->cb[])
From: Benjamin LaHaise @ 2009-08-04 20:21 UTC (permalink / raw)
To: netdev
This patch fixes a case in the transmit completion code which was resulting
in pktgen hanging at the end of a run. The cause is due to the fact that
the ->cb[] area of an skb cannot be used in a network driver's transmit
path, as that area belongs to the network protocol. Pktgen hangs, as it
sends out the same packet multiple times, and vxge's use of this area of
the skb for a temporary list can only add the packet to the temporary list
once (while it may be on the queue many times). The fix is to remove this
abuse of skb->cb[]. Instead, skb pointers are placed into a temporary
stack array, and then free outside of the tx lock. This retains the smp
optimization of doing dev_kfree_skb() outside of the tx lock.

* [4/6] vxge: prefetch RxD descriptors
From: Benjamin LaHaise @ 2009-08-04 20:21 UTC (permalink / raw)
To: netdev
This patch prefetches RxD descriptors which helps to lower the latency of a
cache miss in vxge_hw_ring_rxd_next_completed. This lowers the % of CPU
time used by vxge_hw_ring_rxd_next_completed() where the descriptor is
accessed in profiling netperf on a P4 Xeon from 1.5% to 1.0%.

in the descriptor (which is already in the L1 cache at this point). This
improves netperf rx performance (netperf -L 0,0 -c -H 192.168.254.2 -- -M
131072 -m 131072) by 4.9% on a P4 Xeon host.

The vxge driver will drop a packet in its transmit function if the number
of TxDs available hits 0. Instead of doing that, simply stop the transmit
queue when transmitting a packet with the last available TxD.

wmb() is extremely heavy on x86. The semantics required in the driver are
provided by mmiowb(), so use that and improve tx performance on P4 Xeons by
5-10%.

The peer is dead for a few months ;) so the tunnel was definitely down and no single packet was really exchanged.

It was using UDP.
I killed it (openvpn) now, as I don't need it anymore.
If needed, I can re-enable it.

Is this an openvpn server or client?
Does the warning fire on each authentication, or while the tunnel is
up?
Are you tunneling over UDP or TCP?
Your kernel config, network configuration details and openvpn
configuration might be useful.
Thanks!

* [GIT]: Networking
From: David Miller @ 2009-08-04 19:57 UTC (permalink / raw)
To: torvalds; +Cc: akpm, netdev, linux-kernel
1) IGBVF won't pass traffic due to mis-reading of MAC setting errors.
Fix from Alexander Duyck.
2) Regression in PPP-MP fragmentation handling, fix from Ben McKeegan.
3) PPPOE procfs support can report the final hash chain's entry
"many times", fix from Eric Dumazet.
4) EHEA interface down doesn't unregister the NAPI context --> crash.
Fix from Hannes Hering.
5) Transmits can happen when taking sky2 interfaces down, corrupting
state, fix from Mike McCormack.
6) PCIe completion timeouts programmed incorrectly, and thus out
of spec for PCIe, in IXGBE driver. Fix from Mallikarjuna R Chilakala.
7) net_assign_generic() does memcpy(... count) instead of
memcpy(... count * object_size), fix from Eric Dumazet.
8) pppol2tp forgets to release per-net-namespace metadata during
module unload, leaking memory. Fix from Eric Dumazet.
9) Several reads past end-of-array boundary fixes from Roel Kluin
(airo, ath9k, iwlwifi, libertas, ARP, 3c515, eexpress, tulip,
s6gmac, mISDN).
10) NETPOLL support in IXGBE doesn't consider all queues, and thus
didn't work well. Fix from Peter P Waskiewicz Jr.
11) IXGBE was doing:
adapter->flags & IXGBE_FLAG2_*
instead of:
adapter->flags2 & IXGBE_FLAG2_*
Fix also from Peter P Waskiewicz Jr.
12) Coherent DMA mask not set properly in netxen driver. Fix from
Dhananjay Phadke.
13) MLX4 driver unmaps DMA twice by mistake, oops, fix from Yevgeny
Petrilin.
14) Fix mISDN receive buffer size usage regression, from
Andreas Eversberg.
15) We thought we could rely upon RTNL mutex protection for unicast
address list changes throughout, but unfortunately ipv6 needs
to change these things from software interrupt, so a seperate
spinlock is needed. Regression fixed by Jiri Pirko.
16) IP address printing docbook fix from Tobias Klauser.
17) IPV4 route reverse path filter got broken when it was converted
into a trinary knob, fix from Stephen Hemminger.
18) ISCSI needs to use GFP_ATOMIC allocations in iscsi_offload_mesg().
Fix from Michael Chan.
19) Missing kfree calls from Julia Lawall.
20) 3c59x build fix for gcc-3.2
21) VLB and NULL pointer check fixes in pcnet32 by Bartlomiej Zolnierkiewicz
via Don Fry.

This will cause a null deref trying to get ptr->len in ckpt_hdr_put().

I just figured I'd split up the 0/1 case into getname and getpeer,
mirroring the libc calls. I don't care either way.

My only concern here is whether 0 should be passed in by the caller?
(Not sure, just wondering)
Otherwise this looks good, thanks.

I think we really cannot change behavior here. If the user specifies
"0" in ipi_ifindex we must respect that in ipc->oif. This is an
override, and the ability to override is the very purpose of this
control message.
Even GLIBC makes use of that case of specifying "0" in ipi_ifindex.
We must respect it.
I'm not applying any of these patches, sorry.

* [PATCH 1/2] net: implement a SO_PROTOCOL getsockoption
From: Jan Engelhardt @ 2009-08-04 17:28 UTC (permalink / raw)
To: netdev; +Cc: davem
Similar to SO_TYPE returning the socket type, SO_PROTOCOL allows to
retrieve the protocol used with a given socket.
I am not quite sure why we have that-many copies of socket.h, and why
the values are not the same on all arches either, but for where hex
numbers dominate, I use 0x1029 for SO_PROTOCOL as that seems to be
the next free unused number across a bunch of operating systems, or
so Google results make me want to believe. SO_PROTOCOL for others
just uses the next free Linux number, 38.

* [PATCH 2/2] net: implement a SO_DOMAIN getsockoption
From: Jan Engelhardt @ 2009-08-04 17:28 UTC (permalink / raw)
To: netdev; +Cc: davem
In-Reply-To: <1249406909-24161-1-git-send-email-jengelh@medozas.de>
This sockopt goes in line with SO_TYPE and SO_PROTOCOL. It makes it
possible for userspace programs to pass around file descriptors — I
am referring to arguments-to-functions, but it may even work for the
fd passing over UNIX sockets — without needing to also pass the
auxiliary information (PF_INET6/IPPROTO_TCP).

* [net-2.6 PATCH] igbvf: Allow VF driver to correctly recognize failure to set mac
From: Jeff Kirsher @ 2009-08-04 17:21 UTC (permalink / raw)
To: davem; +Cc: netdev, gospo, Alexander Duyck, Jeff Kirsher
From: Alexander Duyck <alexander.h.duyck@intel.com>
The VF driver was not correctly recognizing that it did not correctly set
it's mac address. As a result the VF driver was unable to receive network
traffic until being unloaded and reloaded. The issue was root caused to
the fact that the CTS bit was not taken into account when checking for the
request being NAKed.

I see. I'll have to think on that a bit.

Okay, I think that would be most productive :)

Hmm.. this also means that if A->C already, then an attempt to also

Hmm.. I think that when you reconnect a dgram socket, it discards all
unread pending data previous received, whether through connection or
via sendto().
What I meant is that restore (and therefore checkpoint) need to know
how to handle skb's sent with sendto() but without proper connection,
where the target socket is still unconnected.
I'm ok with declaring this case unsupported for now and put it in the
'todo' list, and meanwhile work towards getting the current afunix
patches into the cr-dev tree. (As long as it doesn't it will be buried
there forever...)
