staging: android: ashmem: get_name,set_name not to hold ashmem_mutex
Problem:
There exists a path in ashmem driver that could lead to acquistion
of mm->mmap_sem, ashmem_mutex in reverse order. This could lead
to deadlock in the system.
For Example, assume that mmap is called on a ashmem region
in the context of a thread say T1.
sys_mmap_pgoff (1. acquires mm->mmap_sem)
|
--> mmap_region
|
----> ashmem_mmap (2. acquires asmem_mutex)
Now if there is a context switch after 1 and before 2,
and if another thread T2 (that shares the mm struct) invokes an
ioctl say ASHMEM_GET_NAME, this can lead to the following path
ashmem_ioctl
|
-->get_name (3. acquires ashmem_mutex)
|
---> copy_to_user (4. acquires the mm->mmap_sem)
Note that the copy_to_user could lead to a valid fault if no
physical page is allocated yet for the user address passed.
Now T1 has mmap_sem and is waiting for ashmem_mutex.
and T2 has the ashmem_mutex and is waiting for mmap_sem
Thus leading to deadlock.
Solution:
Do not call copy_to_user or copy_from_user while holding the
ahsmem_mutex. Instead copy this to a local buffer that lives
in the stack while holding this lock. This will maintain data
integrity as well never reverse the lock order.
Testing:
Created a unit test case to reproduce the problem.
Used the same to test this fix on kernel version 3.4.0
Ported the same patch to 3.8

"The main part of this merge are Heikos uaccess patches. Together with
commit 09884964335e ("mm: do not grow the stack vma just because of an
overrun on preceding vma") the user string access is hopefully fixed
for good.
In addition some bug fixes and two cleanup patches."

Pull second round of PARISC updates from Helge Deller:
"The most important fix in this branch is the switch of io_setup,
io_getevents and io_submit syscalls to use the available compat
syscalls when running 32bit userspace on 64bit kernel. Other than
that it's mostly removal of compile warnings."

Pull new ImgTec Meta architecture from James Hogan:
"This adds core architecture support for Imagination's Meta processor
cores, followed by some later miscellaneous arch/metag cleanups and
fixes which I kept separate to ease review:
- Support for basic Meta 1 (ATP) and Meta 2 (HTP) core architecture
- A few fixes all over, particularly for symbol prefixes
- A few privilege protection fixes
- Several cleanups (setup.c includes, split out a lot of
metag_ksyms.c)

- The ARM parts of the broadcast timer support, core parts merged
through tglx's tree. This was left over from the previous merge to
allow the dependency on tglx's tree to be resolved.

fixing the fallout from a previous commit in this area.
- A number of smaller fixes scattered throughout the ARM tree"
