Package: src:linux
Version: 4.12.13-1
Severity: normal
One cannot read files of the lowerdir of a overlay, if lowerdir points
to an AFS networked drive. In this case Debian Stretch's OpenAFS client
packet.
If you do this:
mkdir lower upper work to
modprobe overlay
mount -t overlay -o upperdir=upper,workdir=work,lowerdir=lower overlay-local to
ls to
# displays files in upper and lower
cat to/file
# displays the content of file in upper or, if not found there, in lower
Assume OpenAFS is configured to be visible at /afs and up and running:
ls /afs/.inf/test
afs file
ls upper
file upper
mount -t overlay -o upperdir=upper,workdir=work,lowerdir=/afs/.inf/test
overlay-afs to
ls to
afs file upper
# this looks good, all files merged
cat to/file
upper
# looks good, too, "upper" is the content of upper/file
cat to/afs
cat: to/afs: No such file or directory
### !!!!! this should display the content of the file
cat /afs/.inf/test/afs
afs
# this file has a content and does exist indeed
ls -alni to/afs
786508 -rw-r--r-- 1 0 0 4 Sep 21 09:17 to/afs
ls -alni /afs/.inf/test/afs
786508 -rw-r--r-- 1 0 0 4 Sep 21 09:17 /afs/.inf/test/afs
# Those lines match as well
===========
If you stack /afs and local directories with aufs, you can read the
files. So it is not a problem of the networked file system, but of the
"overlay" stacking feature.

If you can reproduce it with
- the current version in unstable/testing
- the latest kernel from backports
