still on the todo-list, I had no time to try this yet...

I don't think ieee1394 is to blame here. See http://lkml.org/lkml/2007/11/29/372
This was the first report of these crashes.
The first one is a similar crash in the ieee1394 code and my first try
was to blame it. But switching to a real network card did not solve
this, as the second crash in that mail shows.
Also Stefan Richter said in http://lkml.org/lkml/2007/11/29/419 this:
"FWIW, eth1394 and the entire rest of the 1394 stack beneath eth1394
are identical between -mm and Linus' tree."
I'm still using the old ieee1394-stack and not the new firewire one,
as eth1394 had not been ported at that time.
It might be possible that these are two different bugs, but two bugs
with same symptom's of corrupted lists at the same time seem unlikely.
(Especially this last report of the oops in 1394 looks rather
strange. Things can only go onto hpsbpkt_queue if they have a non NULL
complete_routine. (see queue_packet_complete() in
drivers/ieee1394/ieee1394_core.c). But a call to a NULL
complete_routine seems to be the cause of one of the two oopses. So it
looks like the hpsbpkt_queue list got mangled. But this list is only
used in this file and all three places that access this list are
protected by spinlocking pending_packets_lock.
So my personal conclusion would be, that someone is writing to memory
that he no longer owns. Most probably 0-bytes. (the complete_routine
got NULLed and the warning about dst->__refcnt being 0).
Use-after-free or something else?

Attached. (Last one I was using with 2.6.24-rc6-mm1. For all other
tests I copied this one and did a make oldconfig)

Interesting. I didn't even know about this file / option.
But four things make an involvement rather doubtful:
a) I do not find a single line like "init_ohci1394_dma: initializing
OHCI-1394" in any of the syslogs.
b) I do not have the parameter ohci1394_dma=early set
c) # CONFIG_PROVIDE_OHCI1394_DMA_INIT is not set
d) I have seen the crash in svc_xprt_enqueue() without eth1394 and at
that try there was not a single firewire device attached.
I will now try broken-out-patches...

Thank you for the reports and for showing how these tools can be put to
good use!
If you have any further suggestions on how to make codiff and the
dwarves to be of more help or find any other bug, please let me know.

Hi Dave,
After Arnaldo got codiff's inline instrumentation bugs fixed
(thanks! :-)), I got my .c-inline-bloat-o-meter to power up
reliably after some tweaking and bug fixing on my behalf...
It shows some very high readings every now and then in the
code under net/.
...Aand... we've a sovereign winner, though it was only fifth
on a kernel wide list (arch/ excluded due to number of
reasons) :-/.

Removing inlines is done iteratively because e.g., uninlining
ctnetlink_parse_tuple affected ..._{proto,ip} prices as well.
i386/gcc (GCC) 4.1.2 20070626 (Red Hat 4.1.2-13)/allyesconfig
except CONFIG_FORCED_INLINING. Tried without some CONFIG.*DEBUG
as well and got slightly better numbers for some functions, yet
the number don't differ enough to be that meaningful, ie., if
there's bloat somewhere, removing DEBUGs won't make it go away.
...After this first aid we're at least below 1k :-).

In 2.4 we used to have (haven't checked recently) performance regressions
with NAPI vs non NAPI (or versus the old BCM vendor driver) on tg3 for
some workloads that didn't fully fill the link. The theory was always
that the reason for that was something like the regular switching in
and out. So I think we saw that problem on tg3 too.

I hoped this question would not come. ;) No, unfortunately I don't have any
numbers. Just the recommendation from AMCC to always use 256 buffers.

Hi Dave,
While reading some nearby code, I noticed this. I'm not 100%
sure if the removal is valid or not nor have interest to dig
it up from history but I suppose you know it better without

It seems that this last report gives the third one: ieee1394 to the pack,
so probably, you can hold on a "minute" - this all needs some rethinking.
(But, if you've begun with this already, let it be clear at last too.)

Yes, since this was no problem with vanilla 2.6.24-rc6, I've probably
gone astray...

OK! But, in the meantime could you send your current .config? I wonder
e.g. if there could be used this new ieee1394 code from
init_ohci1394_dma.c?

* [PATCH] ibm_newemac: Increase number of default rx-/tx-buffers
From: Stefan Roese @ 2008-01-05 9:50 UTC (permalink / raw)
To: netdev; +Cc: linuxppc-dev, benh
Performance tests done by AMCC have shown that 256 buffer increase the
performance of the Linux EMAC driver. So let's update the default
values to match this setup.

ip_fast_csum() called from raw_send_hdrinc() from raw_sendmsg() ran through
the page boundary into unmapped page... Bloody odd, that, seeing that
we have checked iph->ihl * 4U <= length and had done
err = memcpy_fromiovecend((void *)iph, from, 0, length);

The driver on the above site would need quite a bit of work to bring it
up to Linux standards. That work shouldn't be difficult but enough to
keep someone busy for a while. If you have the hardware I'd be happy yo
guide you through the required work. Are you interested in taking up

* Question about arp_error_report() (IPV4): clarification
From: Andy Johnson @ 2008-01-05 8:43 UTC (permalink / raw)
To: netdev
Hi,
In neigh_timer_handler( ), (core/neighbour.c), there is a comment which says:
# It is very thin place. report_unreachable is very complicated
# routine. Particularly, it can hit the same neighbour entry!
# So that, we try to be accurate and avoid dead loop. --ANK
I tried to figure exactly what this comment mean (when dealing with IPV4).
Can someone elaborate in 3-4 sentences on it ?
Why "hit the same neighbour entry" can cause any complications ?
Why is report_unreachable() considered complicated ?
It seems to be simple, or am I missing something?
As far as I understand, eventually ipv4_link_failure()
(net/ipv4/route.c) is called when report_unreachable() is invoked.
(The path is: arp_error_report() calls dst_link_failure(skb), which in
case of ipv4, calls ipv4_link_failure().)
So it seems simply a matter of calling eventually ipv4_link_failure(),
which ends up with generating ICMP.
Regards,
Andy

vanilla -rc6 is fine without these fixes.
The raid-bugs from -rc6-mm1 are probably introduced by
md-allow-devices-to-be-shared-between-md-arrays.patch and that patch
is new in this mm-release.

Aha, I had forgotten about that one.
Looking at all the crashlogs, I do not find another one of this lockdep warning.

I had hoped that I could catch use-after-freeing by using
slub_debug=FZP, but that did not help.
(first oops in http://lkml.org/lkml/2007/12/28/159 )
I think that the main skb structs come from slub and should be
poisoned by this, so it might be some other data structure that is

For my setup: It's a gentoo system, so compiling packages is the
normal way of installing something.
The compile itself is done on a tmpfs so a filesystem corruption there
should be rather impossible. ;)
(The system has 4Gb RAM, so it doesn't even need to swap)
The sources are taken from a nfsv4 share that is served from a
different system. Also gentoo checksums all sources it will use.
After the crashes I also did a checksum of the last installed
packages. Only in one instance there was corruption, all new files
where completely empty. Obviously XFS did not have the time to write
them back to disk before the system crashed.
Also as all crashes show network related traces and the system is
working fine otherwise, I doubt any permanent filesystem problems.
For the raid problems: I was just unable to even start the raid that
has / on it, because of a wrong check in the raid-autostart code.

DEBUG_SLAB is off, because of:
CONFIG_SLUB_DEBUG=y
# CONFIG_SLAB is not set
CONFIG_SLUB=y
But I'm currently did not have the slub_debug-option in my kernel
commandline, because:
a) slub_debug=FZP did not prevent the bug in -rc3-mm2
b) but it took a much longer time to trigger it
c) its a serious slowdown for these compiles
If you think some other slub_debug might catch it, I would try this...

I see your point although I've never seen this in practice
with tg3 or niu.
For a heavy transmit load with TCP, the cpu killer is the ACK receive
processing.
I guess for a datagram send situation it might start to edge up.
However, you're likely deferring TX events (say every 1/4 of the TX
ring or similar) which should make the effect matter much less.
But anyways, it's someone else's driver so if they want to take
TX work into account sure. :-) I'll keep this in mind in my NAPI
changes.
Thanks.

* bridge, packet destination not found in fdb, how to match in ebtables?
From: Denys Fedoryshchenko @ 2008-01-05 6:51 UTC (permalink / raw)
To: shemminger; +Cc: netdev
Hi
In few words: i have problem with bridge, that if some MAC address is not
known, even expired by age bridge will send packet as "flood".
If i am not wrong
in br_device.c
int br_dev_xmit(struct sk_buff *skb, struct net_device *dev)
...
if (dest[0] & 1)
br_flood_deliver(br, skb);
else if ((dst = __br_fdb_get(br, dest)) != NULL)
br_deliver(dst->dst, skb);
else
br_flood_deliver(br, skb);
...
Probably, because packet becoming broadcast in bridge terms, it is useful to
set it something skb->pkt_type = PACKET_BROADCAST; ?
But as i understand after looking in kernel code it can't be set
PACKET_BROADCAST, because it will mess with most of network drivers. So packet
is in ebtables pkttype is matching as "otherhost", same as "good"(non-flood)
packets.
But is there a way to set "flood packet" to some type, that i can match in
ebtables and block it as broadcast?
I had with PPPoE troubles with this, cause PPPoE acting differently than
IP+ARP, and situation when some buggy linksys router start flooding network by
PADT packet to address not existing in fdb, just killing network by "flood" of
this frames to all ports.
Here i see two solutions:
1)Change pkt_type
2)Develop additional module to handle "fdb attributes" (destination found in
fdb or unknown)
I think it is relatively trivial to implement, and it will be useful, as usual
settings available on modern switches, known as "flood limit", but i think i
am not enough programmer to do that. If possible guide me what to do.

Humm... Wouldn't that have made itself evident? The card's not running
in promisc mode all the time, so there should be some problems if the
card would expect the MAC in the reversed order, right? (At least I see
some code that can switch it into promisc mode, so I assume that it is
not enabled all the time).
There _is_ a comment about some cards not generating any TX interrupts
at all. But that seems to predate any card that stores the MAC address
in correct order (the patch for that came after git, the comment
predates git). So assuming that the card wants the address in reversed
order at runtime, would likely imply that _no_ card would generate TX
interrupts (unless promisc?), and the comment basically invalidates that
assumption.

There was once a patch that checked the vendor specific address part,
long ago. No idea what happened to it. But for kexec, I'd say that that
is broken, too.
- ifconfig eth0 hw ether 00:11:22:00:00:01
- $kexec_incantation
- nv_probe sees 00:11:22:00:00:01
- doesn't match the vendor stuff
- becomes 01:00:00:22:11:00
Oops, that's not quite the expected thing.
No way to tell whether we have to reverse from the address alone AFAICT.

This will cause the interface to thrash in/out of polled mode very
quickly when it is doing almost all transmit work. That's something to
avoid, no?

The processing is cheap but it is being done in the poll so it is
scheduled by NAPI. The event rate for TX events can be just as high as
RX. For link state handling, the event rate is always low so won't cause
NAPI to schedule rapidly.

You've written vanilla -rc6 is OK. Does it mean -rc6 with these fixes?
I think it would be easier just to start with this working -rc6 and
simply check if we have 'right' suspects, so: git-net.patch and
git-nfsd.patch from -mm1-broken-out, as suggested by Herbert (I hope,
can compile - otherwise you could try the other way: add the whole -mm
and revert these two). Using current gits could complicate this
"investigation".

Right, the list corruption could be because of use after freeing too.
