Subject3.10.16 general protection fault kmem_cache_alloc+0x67/0x170
I had a machine crash this weekend running a 3.10.16 kernel that
additionally has a few backported networking patches for performance
improvements. At this point I can't rule out that the bug isn't from
those patches, and I haven't yet tried to see if I can reproduce the
crash. I did happen to have kdump configured so I've got a crash dump
that I've been poking at but I'm not an expert here so hopefully
someone can provide some guidance on what I'm looking at and/or where
the bug might be.

Below is the more detailed info with some of my comments interspersed.
If anyone has any questions or suggestions I'd appreciate it.

So it looks to me like the first fault was in a clone system call
when prepare_creds() called kmem_cache_alloc(), then shortly afterward
I received a network packet and faulted again when dst_alloc() called
kmem_cache_alloc(). Both events happened on CPU 11.

Looking at the arguments passed into kmem_cache_alloc:

crash> print cred_jar
$13 = (struct kmem_cache *) 0xffff880c67003800
crash> print ipv4_dst_ops.kmem_cachep
$15 = (struct kmem_cache *) 0xffff880c67003800

Both are using the same kmem_cache pointer.

The cpu_slab pointer doesn't look valid to me and maybe that is the
problem.

The crash utility also has some macros to analyze the SLAB caches but
the output doesn't mean much to me. The only thing that stood out to
me was that CPU 11 appears that everything is allocated. The full
output of that is below for the cache in question. I'm guessing the
problem here was the bad cpu_slab pointer but beyond that I'm not
sure.
