The version applied to Ubuntu Precise was a backported version of the
upstream v12 branch.  So I suspect much of the issues are coming from
that being a backported version.  For Ubuntu Quantal I have reverted
what we had and pulled a clean v12 plus the security fix we had on top.
I have then applied similar fixes to pull that forward to v3.4-rc4 and
it seems to pass very light touch testing here:

  http://git.kernel.org/?p=linux/kernel/git/apw/overlayfs.git;a=shortlog;h=refs/heads/overlayfs.v12apw1

I am pushing it out for perusal as people are asking me about it.  This
includes an updated permissions fix.

Hi Andy,

thanks for updating the OverlayFS-v12 patchset!

Looks like my d_make_root() fix was not complete :-(.
Reverting mine and using yours helped me to run OverlayFS ***w/o***
crashes or call-traces.

Patches applied on top of Linux v3.4-rc5:
1. 100-overlayfs_v12.patch (OpenWrt)
2. my include-fix (should be the same like the one from apw)
3. my touch_atime-fix (same as apw has)
4. d_make_root-fix from quantal (by apw)

I tested OverlayFS with a modified test06.sh script from Jordi Pojol
(testcase-script attached, see [2]).

HINT:
You will need "[PATCH] fs: Increase limit filesystem stacking depth to
3" to run it successfully (patch attached).

Without it you will see in dmesg:
[  476.709418] overlayfs: maximum fs stacking depth exceeded

FYI:
Depth "2" was defined in "fs: limit filesystem stacking depth" patch
from Miklos.
Not sure if I can loosen that a bit (security issue?).
Jordy told me in private conversation he has dropped that patch completely.

I will re-test with Andy's "overlayfs.v12apw1" GIT branch [3] (pulled
into Linux v3.4-rc5).

Hope this helps other users and developers.

As promised I have tested with Andy's patches +  limit-fs-stack-depth=3.
The testcase script runs completely and successfully (all loop and
overlayfs mount-points unmounted properly).

On 1st tests: Looks very good to me :-).

Feedback as tarball attached (kernel-config, dmesg and testcase script
+ results).

Have fun!
