Hi,
I've got an AMD64x2 system, x86_64, SMP, PREEMPT, with 4Gb of RAM,
running 2.6.29.1 (most recently running 2.6.29-rc5 for a while before
that) which crashes when I run 'tcpdump host x.y.z.n'. I'm on
linux-kernel, but not netdev, so please keep me in the headers.
I have't tried wireshark or ethereal yet, since I just wanted to see
if packets were getting forwarded. My main firewall is a m0n0wall
WRAP board, so there's no much to do there debugging wise. Ping does
seem to work from both the firewall (192.1681.254) to 192.168.2.200
once I put in the proper static route via sail
(192.168.1.3/192.168.2.3).
Background: I'm working on setting up a PXE boot environment for a new
box without a CDROM. My current system, sail, has eth0 on the
192.168.1.0/24 subnet, with an IP of 192.168.1.3, and my WAN router
(with DHCP) is setup at 192.168.1.254. So I setup eth1 on the
192.168.2.0/24 subnet, with a DHCP server on my host, and an IP of
192.168.2.3 on that subnet. More details:

I don't have any ip_tables stuff loaded, which might be needed for my
setup, but which doesn't seem to be implicated in this crash right
now.
I can now PXEboot my client just fine, but connections from the
192.168.2.200 PXE host don't seem to get properly forwarded out to the
internet so I can continue the network boot and install of Debian. So
to figure out what I was going wrong, I would try to do 'tcpdump host
192.168.2.200' on 'sail' and it would instantly hang. I mucked around
and got netconsole setup and got the following ksymoops.
Hopefully they'll be helpful. I'll be happy to try and bisect this,
and I'll start moving back in versions to see if I can find where this
crash takes place.

I'll re-build without USB_MON on my system and see what happens. If

Ok, I've rebuit the system, and in my initial quick remote tests,
tcpdump doesn't crash the system. Now I also admit that my test box
on the 192.168.2/24 subnet isn't powered on right now, so who knows.
I'll see if I can go back to 2.6.28 with USB_MON compiled in, and see
if that causes a problem. Who knows...
More later tonight if I'm lucky.

The libpcap supports usbmon. Perhaps it scans something.
The big problem with usbmon is, it has to trust what drivers
stuff into URBs. Bet it's your uvcvideo. A rough driver, that.

Well I think that usbmon is probably at fault here for trusting
drivers too much and not doing any sanity checking. But I can try
removing the uvcvideo driver and seeing if I can get the system to
crash then.
I was busy last night and didn't have a chance to even touch the
system. Hopefully more time tonight, but I'm not sure.
Thanks for the hints, I'll give them a whirl.

By the way, please send me a full dmesg from the affected system
and kernel. Any post-boot dmesg will do: I only want to see if
IOMMU is active, where the aperture is, and if 0x20a15cc0 is a
valid physical address.

I didn't get a chance to play with this last night, but since I'm now
running 2.6.29.1 with USB_MON turned off in the config, it hasn't
crashed when running tcpdump at all.
I'll recompile the kernel with USB_MON as a module and test it out
some more.
Here's a dmesg of bootup:

Ok, I've confirmed that it's usbmon under 2.6.29.1 on x86_64 which causes
complete system lockups when doing 'tcpdump host ##.##.##.##'. I
compiled usbmon as a module, started a tcpdump and couldn't get a
crash.
Loaded the module with tcpdump still going, no problems. Stop and
restart tcpdump, bang! Instant hang. I'm now building 2.6.28 to see
if that works properly or not. I suspect I might have to go back
farther, but I'm not sure.
Any suggestions of a known good state I should start bisection from?
Thanks,
John

No suggestions, sorry. The part of usbmon that peeks at DMA-ed data
wasn't touched since December 2006. It worked fine since then,
your oops is the first. So, I don't expect bisection to help.
At best you're going to find the commit where uvcvideo was merged.
The right way forward is to deduce what's going on, IMHO. Maybe
usbmon is trying to take an address in the GART aperture and convert
it into a struct page. Or the direction in URB mismatches endpoint.
Or any number of other things.
I'm working on it, but I'm not done with puzzling out the dmesg
you sent me, sorry again.

I guess my next step would be to unload that module and see if the
crash happens while I have usbmon loaded.

I do have the Radeon driver installed, with DRI, etc.

Let me know if you want me to put in debugging messages or try for
more netconsole output. I built a bunch of kernels last night, but
ran out of reboot time (learning git...) to test them. I figured I'd
go back to 2.6.26 and see if I had the problem there. If not, it's a
good start for bisection.
I'll keep poking at this, though tax time is starting to fill my time
right now too. :]

So 20a15000 is in the aperture. Oh well, I screwed up. I meant to
check for this back in 2006 but forgot, and miraclously it worked
until now.
Here's the problem:
pg = phys_to_page(dma_addr);
map = kmap_atomic(pg, KM_IRQ0);
offset = mon_copy_to_buff(rp, offset, map + page_off, step_len);
kunmap_atomic(map, KM_IRQ0);
Obviously we don't want the page that's overlayed by the aperture,
but the page where IOMMU is pointing.

Thanks for finding this! I was working on getting 2.6.25 built and
running, but it hates my Forcedeth ethernet ports and won't bring them
up, which complicated testing immensely. It's tough when your home
directory is on NFS and the network is down...
I'm happy to test any patches you have.
Thanks,
John
Pete,
Is there any update on this bug? I'm off for five+ days of vacation,
but I'll be happy to test when I get back, and even build test kernels
while I'm away if I find some time.
Thanks,
John
