This means that some code somewhere (we are not told where) modified an object from
the ip_conntrack cache after destroy_conntrack had freed it up.
Looking at the data pattern, it is probably an INIT_LIST_HEAD() against a
list_head field which is 120 bytes into the object. (problemat - start). Or
a list_del() against a different object which erroneously remains on a list
with this object.
Manfred has extra toys in the works which will be able to unmap slab objects
from the kernel virtual address space when they are freed. When this debug
code is working (it will run slowly) we will get an oops at the site of the
bug.

This might explain the crashes I've seen in my routers but been unable
to capture so far (and without the extra slab debugging I don't know if
I would have been able to find it or even get a decent capture...)
Patch attached that should fix the problem, not tested or even compiled.
Joe, can you please please test it and report back?

You are correct. It was a list_del() that caused it (at least I think
so, it's 2am right now).
1. conntrack helper adds an expectation and adds that to a list hanging
of off a connection.
2. the expected connection arrives. the expectation is still on the
list.
3. the original connection that caused the expectation terminates but
the expectation still thinks it's added to the list.
4. the expected connection terminates and list_del() is called to remove
it from the list which doesn't exist anymore. boom!

This will be a nice feature, might make it easier to find the bugs.
Too bad it can't help work out the relationship between structs... I had
to use pen and paper to work out the relationship between connections
and expectations :) That part is almost a little bit hairy.

Never argue with an idiot. They drag you down to their level, then beat you with experience.
We have 12 hours uptime so far with this
patch, and everything is good so far -
Will report any change in status -

Ok, the previous patch was a little bit incorrect. It did fix the use
after free bug (which can cause corruption if the slabmemory is
reallocated before we write to it) but lost some internal information.
I can't see that we use this anywhere after this point but here's the
proper patch.
Sorry about that.
