I'm not seeing anything on the console - is there additional conntrack
debugging I can enable? I will try building in netfilter debug again.

But I did just get this crash while testing again:

I am using CBQ myself with recent kernels and never found it
'borrowing', could you post a copy of your rules, or better, a subset of
them desmonstrating the problem ?

Of course I was joking, and no need to explain this is at least
misleading, but if it's old enough it might be treated as part of user
API. Probably somebody wanted to save an additional variable, and btw.
in some languages there is one verb only, something like here:

"bounded
	Signifies that this class will not borrow bandwidth from its siblings.

 isolated
        Means that this class will not borrow bandwidth to its siblings"

[from man(8)tc-cbq]

So, consider it documented ;-)

Well, congratulations! But, please, remember this nice, but a very
complex tool is rarely improved/fixed now, mainly not to break some
backward compatibility, while not much reporters/testers either. But,
of course, any feedback is welcome...

ell, you didnt describe your benchmark method.

1) your results were on different rx/tx workload, and describing your
workload is very important to be able to compare results. Then it should
be exactly same workload.

For example, when tx/tx load is high enough, less cpu overhead is spent
on irq processing, since each IRQ delivers more packets per round.

2) you didnt sent "perf top" results for the second/last one.

  But the first "perf top" results showed less than 1% of cpu time was
used by cache cleanup. I guess you dont want to focus on this, since
its already very good.



Usually, when we want to bench a router, we study how it deals with DDOS
workload. Feeding lot of packets to the device and study what percentage
of them are actually transmitted. Goal being 100% of legit packets of
course.

Route cache settings matter in DDOS situations, and the flush operation
can have a big impact on dropped frames because of cpu/ram congestion.

Because of 600 seconds oscillations, its pretty hard to study exact cpu
use of a router, unless taking samples on long periods.

Doing that now. Turning on a bunch of debug options like netfilter debug
and kmemleak causes it to trigger a lot less often, so I've reverted to
the "known bad" config that triggers this reliably.

Turning on netfilter debug and kmemleak resulted in a large number of:

[18493.405393] nf_conntrack: table full, dropping packet.
[18503.165713] kmemleak: 2 new suspected memory leaks
(see /sys/kernel/debug/kme
mleak)

etc. The memleak warnings don't look all that useful (attached what was
left in the buffer anyway) but the slowdown (KSM and kmemleak both at
near 100% CPU) seems to affect the timing of this and make it less
likely to trigger. The box fell over as I was rebooting it after a few
hours, and just after I detached the serial console to reset it :(

Attached current config. Send you the netfilter trace shortly.

Jon.

Obviously I find them useful here, but if more people feel the

I think I'm just missing the put in the open function, the code
already handles the netif and the file disappearing independently.

Thanks for spotting this one, I'll fix that in the next post.

The driver still only does the minimum feature set to get things going.
GSO is an obvious extension, but I wanted the code to be as simple
as possible to find all the basic bugs before we do anything fancy.

That may well be, I haven't tried vlan. What do you think it should do
then?

Again, minimum features to get things going. qemu fails to open
the device if these ioctls are not implemented, but any of the
more advanced features are left out.

Thansk for the review,

OK. I will look at it. The traffic is actually in a subclass (1:18) so
this may explain it. It definitely does not fit my "political
principles". Borrow should mean how many times the class has borrowed
and overactions should mean the whole lot of overs - delay, borrow,
drop, etc. At least that were the semantics on BSD and other
implementations I dealt with before Linux. 

My problem as well is that my C has always sucked bricks and I use it
once a year when I run into a problem like that. So it takes me a while
to trace it and figure it out.

Well, I know CBQ reasonably well from a "network engineer" perspective.
I used to run it production in an ISP 1998 and after that in an SMB
2002-2007. I have also been running it in lab and on my home network for
10+ years. Mostly on BSD though. There was even a point where I
maintained a fork of the patches before they went into the main tree.
The sole reason I ditched BSD was that they plugged it into the pf
framework and it became too big of a hassle to port/maintain the
configs.

I know what I am doing and HTB is not what I want. It is a good algo for
expressing classic commerical relationships (CIR/PIR). It is worse than
CBQ for "sharing" where all of the apps that share are your own and the
scheduler/estimator is good.

Thanks for all the help.

In addition or instead of RPS, using the 82598 software developers manual 
you could pretty quickly code up a queue spreading model using the vlan 
tags and VMDq mode.  I believe you can just turn on VMDq mode and get the 
vlan filtering behavior enabled with a single register write.

It appears the VFTA table has some entries in it that can control the 
queue picked for each VLAN id hash match in the table.  I think even 
filling this with an incrementing value would allow vlan packets with 
non-IP traffic to be automatically spread out to all available queues (as 
long as there was enough randomness in the hash result for the input vlan 
ids.

Hope this helps, you might want to consider sending queries like this in 
the future to e1000-devel@lists.sourceforge.net

That's a good optimization - saves calls to driver and hash
calculation for every skb (for devices that have select_txq
but find that they can cache after the first time).

Ok - applied. Noise gone... however I'm not sure whether I'll be able to 
keep dma-debug going long enough to catch anything. num_free_entries 
keeps dropping... looks like entries are not freed. I'm running with a 
huge number for now & sky2 as the driver filter. Is there a reason that 
entries wouldn't be unmapped, or is dma-debug.c just not processing the 
unmap correctly?

For now I could only find some explanation in this place:

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;f=net/sched/sch_cbq.c;h=3846d65bc03ec7a7de7e6ca674dc6c2b255dc570;hb=HEAD

820 static __inline__ struct sk_buff *
821 cbq_dequeue_prio(struct Qdisc *sch, int prio)
822 {
...
863                         if (borrow != cl) {
864 #ifndef CBQ_XSTATS_BORROWS_BYTES
865                                 borrow->xstats.borrows++;
866                                 cl->xstats.borrows++;
867 #else
868                                 borrow->xstats.borrows += qdisc_pkt_len(skb);
869                                 cl->xstats.borrows += qdisc_pkt_len(skb);
870 #endif

So, xstats.borrows is updated for lender as well, which might look
wrong/right/funny (depending on your political principles ;-).

It could be your case if the class above has an unbounded child class.
Otherwise, it needs more searching. Btw, I'm not the CBQ expert to
verify (without learning the specs) these borrowing relations. (As a
matter of fact, within a few years I didn't find here many traces of
such (active) experts, so my recommendation would be HTB or HFSC
unless you really know what you're doing ;-)

[...]

The driver's ndo_select_queue() implementation calls it before
returning, if and only if sk_may_set_tx_queue() is true and its
selection is dependent only on the flow id.

As an example, ixgbe's selection function:

        static u16 ixgbe_select_queue(struct net_device *dev, struct sk_buff *skb)
        {
        	struct ixgbe_adapter *adapter = netdev_priv(dev);
        	int txq = smp_processor_id();
        
        	if (adapter->flags & IXGBE_FLAG_FDIR_HASH_CAPABLE)
        		return txq;
        
        #ifdef IXGBE_FCOE
        	if ((adapter->flags & IXGBE_FLAG_FCOE_ENABLED) &&
        	    (skb->protocol == htons(ETH_P_FCOE))) {
        		txq &= (adapter->ring_feature[RING_F_FCOE].indices - 1);
        		txq += adapter->ring_feature[RING_F_FCOE].mask;
        		return txq;
        	}
        #endif
        	if (adapter->flags & IXGBE_FLAG_DCB_ENABLED)
        		return (skb->vlan_tci & IXGBE_TX_FLAGS_VLAN_PRIO_MASK) >> 13;
        
        	return skb_tx_hash(dev, skb);
        }
        
would not call netif_sk_tx_queue_set() in the first two cases, but could
do so in the last two cases if sk_may_set_tx_queue(skb->sk) is true.

If the device only has a single TX queue this can't possibly help it.

In the case where a device has multiple RX and TX queues, I think it is
preferable that contention for TX queues is likely to be among cores
that are close together, not spread over the whole system.  I assume
that RPS will normally be configured to spread traffic from each
hardware RX queue to a group of cores that are close together (same NUMA
mode, maybe sharing some caches).  In that case it would also be
desirable to limit contention for a TX queue to within these same groups
of cores, so TX queue selection ought to match hardware RX queue
selection.  So I don't think this should conflict with RPS.

The intent here is to make it worthwhile to calculate that expensive
hash on the TX side.

+void netif_sk_tx_queue_set(struct net_device *dev, struct sock *sk,

I guess I didn't understand this then, who calls this function? Is
it after getting the txq from the driver? In which case, are you
planning to do something like:

static struct netdev_queue *dev_pick_tx(struct net_device *dev,
                                        struct sk_buff *skb)
{
      u16 queue_index;
      struct sock *sk = skb->sk;

      if (sk_tx_queue_recorded(sk)) {
            queue_index = sk_tx_queue_get(sk);
      } else {
            const struct net_device_ops *ops = dev->netdev_ops;

            if (ops->ndo_select_queue) {
                  queue_index = ops->ndo_select_queue(dev, skb);
                  queue_index = dev_cap_txqueue(dev, queue_index);
            } else {
                  queue_index = 0;
                  if (dev->real_num_tx_queues > 1)
                        queue_index = skb_tx_hash(dev, skb); /*already
capped */
            }

            if (sk_may_set_tx_queue(sk))
                  sk_tx_queue_set(sk, queue_index);
        }
        skb_set_queue_mapping(skb, queue_index);

What about adding a new handler in struct sctp_af, like get_xfrm_dst() that will 
be called after get_saddr()? In case of IPv4, it will not do anything.

Nicolas

When forwarding, yes.

Correct, that's exactly what it's for.

Only the return value of ndo_select_queue() is capped; the cached value
is assumed to be valid.

Will this work with RPS and device driver hashing?
I am thinking of the problem where the hardware hash function is
Toeplitz (per NDIS spec), and the software hash function is Jhash
(what kernel uses because it is cheaper).

Therefore the transmit hash and receiver hash will be different.

The folks working on the Open vSwitch project are addressing some of these issues also.  You might want to check them out at openvswitch.org, although I have no idea what sort of view the Linux networking community has towards their work.

I am confused about this - isn't the txq# and rxq# already
matched due to the check for skb_rx_queue_recorded?
sk_dst_cache is also not set for these routing/forwarding
workloads, this can be relied only for locally connected
xmits.

Other than that, I saw netif_sk_tx_queue_set is not called.
And dev_pick_tx has already capped automatically, you probably
don't need another here?

This seems to keep reference to device as long as character device is
open, which, if I understand correctly, will start printing error
messages to kernel log about once a second if you try to remove the
device.

I suspect the best way to fix this issue would be to use some kind
of notifier so that macvtap can disconnect on device removal.

I am surprised there's no GSO support.  Would it be a good idea to share
code with tun driver? That already has GSO ...
Also, network header pointer seems off for vlan packets?

All of these seem to be stubs, and tun has many more that you didn't

* [RFC] [PATCH] net: Add support for ndo_select_queue() functions to cache the queue mapping
From: Ben Hutchings @ 2010-01-28 17:38 UTC (permalink / raw)
  To: netdev; +Cc: linux-net-drivers

We think it's worth matching up RX and TX queue selection for a socket
when the queues share an interrupt.  Currently the default TX queue
selection is unlikely to match RX queue selection.  TX queue selectionc
can be overridden by the driver to match RX queue selection, but at the
expense of caching.  We found that without caching the cost of
recalculating the the hash in software for each packet outweighed the
benefit of good queue selection.

This adds two simple helper functions: sk_may_set_tx_queue() reports
whether the queue mapping should be cacheable for a socket, and
netif_sk_tx_queue_set() sets it after validating the queue index.  This
will allow drivers to evalulate expensive queue selection functions
(such as Toeplitz hash functions) only once for connected sockets, and
to avoid doing so for other skbs.

This test in dma-debug is bogus. Because the debug code matches
dma based on address and size; and is perfectly valid to sync a value
less than size. This is the patch I sent earlier, it isn't 100%
correct but it will let you keep testing
....................................


This should fix the dma-debug API code (and documentation), to
avoid false positives when sync is done on a partial map.

pure luck I guess, since you use two cpus here instead of one, but
nothing guarantee this.

Not sure I understand your goals. Previous numbers were with less
trafic ?

What do you want ? your cpus being idle, or your router being able to
forward packets without drops ?

Good, but if you drop packets when real garbage collection is done, you
loose. Make your choice :)

Update: I played with dma-debug. Was being disabled due to lack of 
memory. I forced it back on while pumping traffic through and got this:
