Hi all,

I've been running into this use-after-free in mprotect() with trinity on
latest linus/master. It's relatively easy to reproduce, it takes
anything from 1-6 hours and I've hit it some ~12 times in total (on
different VMs with no preceding errors/taints other than OOM stack traces).

The problem seems to be triggered when both calls to
anon_vma_chain_alloc() in anon_vma_clone() fail -- it jumps to
'enomem_failure' and backs up through vma_merge() to mprotect_fixup()
where it does the 'if (start != vma->vm_start)' and by this point 'vma'
has apparently been freed.

I'll attach what I think is the best example since everything (alloc +
free + use-after-free) seems to happen in sys_mprotect() in the same
process and it has a little bit of debugging info that I inserted in
anon_vma_clone(), although I've also seen the alloc + free +
use-after-free happen in 3 different processes, with alloc happening in
clone() and free happening in exit().

my printks in anon_vma_clone() (at 'enomem_failure'), just before the crash:

dst:
->vm_start=00007f77982d0000
->vm_end  =00007f77983d0000
->vm_mm   =ffff8800b8956900
->vm_flags=100173
	VM_READ|VM_WRITE
	VM_MAYREAD|VM_MAYWRITE|VM_MAYEXEC
	VM_GROWSDOWN
	VM_ACCOUNT
->vm_ops  =          (null)
->anon_vma=ffff8800b8668300

src:
->vm_start=00007f77983d0000
->vm_end  =00007f77985d1000
->vm_mm   =ffff8800b8956900
->vm_flags=100173
->vm_ops  =          (null)
->anon_vma=ffff8800b8668300

The stack trace where the use-after-free happens:

  [<ffffffff81354413>] mprotect_fixup+0x523/0x5a0
   - mm/mprotect.c:312 if (start != vma->vm_start) {
  [<ffffffff81354827>] SyS_mprotect+0x397/0x790
   - mm/mprotect.c:437 error = mprotect_fixup(vma, &prev, nstart, tmp, 
newflags);

 From KASAN (annotated with lines/line numbers):

INFO: Allocated in __split_vma.isra.34+0x161/0x730 age=753 cpu=3 pid=16769
         kmem_cache_alloc+0x1af/0x1e0
         __split_vma.isra.34+0x161/0x730
          - mm/mmap.c:2341 new = kmem_cache_alloc(vm_area_cachep, 
GFP_KERNEL);
         split_vma+0x7f/0xc0
          - mm/mmap.c:2400 return __split_vma(mm, vma, addr, new_below);
         mprotect_fixup+0x3e8/0x5a0
          - mm/mprotect.c:320 error = split_vma(mm, vma, end, 0);
         SyS_mprotect+0x397/0x790

INFO: Freed in vma_adjust+0x8e6/0x1390 age=32 cpu=3 pid=16769
         kmem_cache_free+0x19a/0x1b0
         vma_adjust+0x8e6/0x1390
          - mm/mmap.c:797 kmem_cache_free(vm_area_cachep, next);
         vma_merge+0x7c7/0xc20
          - mm/mmap.c:977 /* (cases 1, 6) */
         mprotect_fixup+0x1b6/0x5a0
          - mm/mprotect.c:305 *pprev = vma_merge(mm, *pprev, start, end, 
newflags,
         SyS_mprotect+0x397/0x790

So it *looks* to me like it all happens within one call to mprotect()
and that this is the very general flow:

SyS_mprotect()
  - mprotect_fixup()
     - split_vma()
        - split_vma.isra.34()
           - vma = kmem_cache_alloc() // succeeds
     - vma_merge()
        - vma_adjust()
           - kmem_cache_free(vma)
           - goto again; // ???
           - anon_vma_clone()
              - kmem_cache_alloc()
                 - return NULL
              - kmem_cache_alloc()
                 - return NULL
              - return -ENOMEM
           - return -ENOMEM
        - return NULL
     - vma->vm_start // use-after-free

I'll try adding some more printk()s and also see if I can narrow it down
so reproducing is faster.
