io-pktv4-hc crash   
On one of our systems we have experienced io-pkt crash.

I am attaching a file with core and list of pci devices.

Any idea what could have gone wrong?

Thanks, PKY

Can you also attach the io-pkt-v4-hc binary, any drivers / 
dlls loaded therein (looks like devnp-shim.so and devn-e1000.so)
and your libc.so.

Thanks,

> I am attaching a file with core 

I unzipped it, and sure enough, all there was,
was a core file (and the pci info).

For us to examine a core file, we need:

1) your core file (got it)
2) your io-pkt binary (didn't get it)
3) ALL the libs loaded by io-pkt, which
   includes the driver .so file, perhaps
   qnet, and please libc as well

To figure out what libs you need to include
in the tarball, please run:

  # pidin -p io-pkt-v4-hc mem

Re: RE: io-pktv4-hc crash   
I hope all the files needed are in the zip file.

I use devn-e1000.so. Is devnp-e1000 driver available? I couldn't find it.

Thanks, PKY

No it isn't available yet.

RE: RE: io-pktv4-hc crash   
There is no core file (eg io-pkt-v4-hc.core)
in the archive.

Never mind - I use the email interface to the
forums, which doesn't display previous posts.

I found the core file from 17 dec 08, and
am looking at it now.

RE: RE: io-pktv4-hc crash   
Ok, if all the binaries are in sync, you
didn't die in the (e1000) driver at all.

Looking at the backtrace for the thread
that SIGSEGV'd, it blew up in a utility
function called b_to_q() which tried to
memcpy() to a null pointer.  This was all
called by pppinput() - nothing to do with
the ethernet driver (or PCI) AFAIK.

Is this difficult to reproduce?  I really
don't know squat about ppp (I know a little
about pppoe) but if you want to compile 
io-pkt-v4-hc with the -g -O0 flags, and
send me another core, I can try to learn
a bit more - there's only so much I can
glean from disassembling x86.

Anything interesting about your ppp
configuration, or when this core occurs?

RE: RE: io-pktv4-hc crash   
We also need to know which version of the stack is being used.  Is it a
custom build, a milestone build or are you running 6.4.0?

	Thanks,
		Robert.

Its 6.4.0 build, all executables are from 6.4.0 DVD downloaded from your site.
