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_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

- 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);

vma_merge+0x7c7/0xc20
- mm/mmap.c:977 /* (cases 1, 6) */

- 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.
