The problem will be waiting, just pushed into dark corner. ;)
The card+driver need to survive empty rx buffer list anyway.
This issue will come back with people attacking bufferbloat issues
(they will want to reduce queue sizes and so increase the frequency
when free rx buffers run out).

Sure. In this series it's patch 16 --- because it was trivial to do. Pending
patches only wrap the existing behaviour (where clearly scheme #1 or #2
is used).

It would help what the whole point of shuffling these drivers around
in arbitrary ways is. Splitting them up for the actual protocols might
make some sense, as would giving a subdirectory to every non-trivial
driver. But what whole vendor split, even if consistently implemented
seems like a lot of wanking for very little juice.

There's simply too much stuff under drivers/net right now, I

You could use some evil shift tricks to cut some instructions if you like. ;-)
Examples below.

size_t size = sizeof(struct neighbour *) << shift;
Or, since later get_order(size) is used:
unsinged int size_shift = shift + order_base_2(sizeof(struct neighbour *));

The controllers you are familiar with might do head-of-line blocking
when a single RX queue is empty. But any multiqueue controller that is
supposed to support untrusted queues (required for SR-IOV) had better
not. This is certainly not done on Solarflare controllers (packets for
that queue just get dropped until it's refilled) and I doubt it's done
on many others.
I also think it's quite reasonable for the RX queue to stop interrupting
when the host is already too busy to refill it. Some drivers might not
recover correctly, but this is not a hardware issue.

I agree this is a reasonable and generic way to deal with empty RX
queues.

* recommended way to support duplicate IP addresses on different VLANs?
From: Chris Friesen @ 2011-07-11 14:58 UTC (permalink / raw)
To: netdev
Hi all,
We've got a server that sits on multiple VLANs. Each VLAN is segregated
and doesn't know about the others. The IP address ranges in each of the
VLANs may overlap, and the server may be assigned the same IP address in
multiple VLANs.
We've got a messy solution now involving unique internal addresses and
NATing between those and the duplicate external addresses, but I'm
wondering if there is a cleaner way to handle this.
It seems like network namespaces would work, but it would require
multiple instances of our software which is a dealbreaker.
Is there any other way to deal with this scenario?
Thanks,
Chris

Namespace file descriptors if/when they get accepted.
Or then binding sockets to devices (SO_BINDTODEVICE) might work.

I think it would be more appropriate to use get_unaligned_le16() here.
No casts should be needed then.
That's not an objection, just a suggestion :)

I am still undecided on this. Understand the need, but don't like idea
of bridge behaving in non-conforming manner. Will see if IEEE 802 committee
has any input.
Also, don't want to build more knobs in with sysfs that are per-bridge.
Eventually, the plan is to make all the setting per-port with sysctl's
like IPv6.

Hmm...SO_BINDTODEVICE looks interesting. I would imagine we'd still

The intention here is to replace frame types from enum ath5k_pkt_type
with their AR5210-specific counterparts. So the intention is definitely
to have breaks here.
Unfortunately, AR5210 cards are extremely rare these days. I have one,
but it only works with old motherboards. It would take me half a day to
dust off that system, compile the kernel and check the patch. But I
assume your patch is fine. At least it's very unlikely to break anything.

arp_filter should help.
Also, you may want to use conn-trck tables. This lets packets coming
in one or more interfaces use a specific conn-track cache. Might help
keep the identical IPs from colliding in their conn tracking.

Could you pretty please create signed patch(es) (git could create them
for you) so we could commit them into LTP repository.

* "tm->when" at /proc/net/tcp shows some negative numbers.
From: Andreas O @ 2011-07-11 16:47 UTC (permalink / raw)
To: netdev
Dear devnet list,
I am doing some performance improvements on linux-2.6.33.15 with
real-time support. When my tests fails I observe that "tm->when" at
/proc/net/tcp shows
some negative numbers. That negative number is the difference of
"timer_expires - jeffies" and in this case timer_expires is smaller
than jiffies.
Does this negative number indicates a bug in the stack?

Not necessarly.
If the thread handling timers is delayed (because of other more urgent
RT things), the delay between timer is fired and handled could be long.

* CAN: major update for the Controller Area Network LTP tests

CAN: major update for the Controller Area Network LTP tests
This update for the LTP tests are dealing with CAN filters and the
CAN frame flow down to the CAN netdevice and vice versa.
The patch removes all the obsolete stuff from the source code directory
that has been originally used to pick the tests from. The two new tools
also reside in the SocketCAN SVN svn://svn.berlios.de/socketcan/trunk/test
tst-filter: New filter test tool in *one* programm (easy to use & handle)
tst-rcv-own-msgs: Checks the CAN frame flow inside the networking stack
Additionally the virtual CAN driver needs to be loaded with a special
commandline option to perform the CAN frame flow test correctly.

-/*
- * tst-bcm-server.c
- *
- * Test programm that implements a socket server which understands ASCII
- * messages for simple broadcast manager frame send commands.
- *
- * < interface command ival_s ival_us can_id can_dlc [data]* >
- *
- * The commands are 'A'dd, 'U'pdate, 'D'elete and 'S'end.
- * e.g.
- *
- * Send the CAN frame 123#1122334455667788 every second on vcan1
- * < vcan1 A 1 0 123 8 11 22 33 44 55 66 77 88 >
- *
- * Send the CAN frame 123#1122334455667788 every 10 usecs on vcan1
- * < vcan1 A 0 10 123 8 11 22 33 44 55 66 77 88 >
- *
- * Send the CAN frame 123#42424242 every 20 msecs on vcan1
- * < vcan1 A 0 20000 123 4 42 42 42 42 >
- *
- * Update the CAN frame 123#42424242 with 123#112233 - no change of timers
- * < vcan1 U 0 0 123 3 11 22 33 >
- *
- * Delete the cyclic send job from above
- * < vcan1 D 0 0 123 0 >
- *
- * Send a single CAN frame without cyclic transmission
- * < can0 S 0 0 123 0 >
- *
- * When the socket is closed the cyclic transmissions are terminated.

The correct fix is to make cc1 a signed variable.

* Crash in e1000e driver, 3.0-rc6+
From: Ben Greear @ 2011-07-11 18:10 UTC (permalink / raw)

This is lightly patched with some NFS related patches. This was
shortly after boot..I don't think we had even done any real NFS
work yet.
The warning we see fairly often..the crash below is new.
I just pulled and re-built, so it's possible that the code listings

* Bridging behavior apparently changed around the Fedora 14 time
From: Greg Scott @ 2011-07-11 18:25 UTC (permalink / raw)
To: netdev; +Cc: Lynn Hanson, Joe Whalen
I ran into a strange situation - I am using a firewall set up as a
bridge. Physical device eth1 is the private LAN side, eth0 is the
public Internet side. I setup bridge br0 to bridge eth0 and eth1
together. I need a bridge because this site has a couple of nodes on
the LAN side that need real public IP Addresses.
This site also has a few web and ftp sites. These are NATed behind the
firewall, but internal users need to see them the same way as the rest
of the world. So I use some iptables SNAT and DNAT rules to make this
happen. Device br0 has the relevant public IP Address(es) and then NATs
to the appropriate private IP Address(es). The ruleset works and the
system has been up and running for several years.
I recently replaced the old system with a new one running Fedora 14 and
that's when the weird behavior started.
Now, when internal people try to look at those web/ftp sites using the
public IP Addresses, they get nowhere. Unless I watch with tcpdump -
and then while I'm watching , all works as it should. With some help,
we figured out the reason it works when watching with tcpdump - because
tcpdump puts the device being monitored into promiscuous mode.
And, sure enough, when I do:
ip link set br0 promisc on
everything works as it should.
Looking at "ip link show", it looks like bridge br0 takes on the MAC
address of physical NIC eth0. But the internal LAN is connected to
physical eth1. I wonder if this behavior is different than the older
version? If the MAC Address for bridge br0 is different than the
physical device I'm actually connected to, I wonder if bridging "thinks"
I'm trying to hit a foreign MAC Address - especially since I'm doing
both SNAT and DNAT on the same packet?

Hmmmm - so a packet comes in on eth1, with a destination MAC Address
belonging to physical eth0. So eth1 throws it away because it "thinks"
this is a foreign MAC Address? But this all worked before, so what's
different? Or were earlier bridges in promiscuous mode by default and
now they're not? Have I stumbled across a new bridging bug? Is the
best workaround to just put br0 into promiscuous mode?
Thanks
