Package: src:linux
Version: 3.2.41-2
Severity: important

Dear Maintainer,

on the 3.2.0-4 kernel, access to a directory via a symlink on a tmpfs
filesystem gives "permission denied" - if the tmpfs filesystem mountpoint
is not owned by root. The same setup on a 2.6.32-5 (Squeeze) system 
works fine.

Apparently, access via a symlink on a tmpfs filesystem fails if the
mountpoint is not owned either by "root" or by the user attempting to
use the symlink.


This is my test setup:

* Two user accounts, "henrik" and "dummy"
* Create directories /test/fsdir and /test/memdir
* Mount a tmpfs filesystem on /test/memdir
* In /test/fsdir: ln -s ../../home/henrik .
* In /test/memdir: create the same link
* Change owner of tmpfs mountpoint: chown dummy:dummy /test/memdir

Now, try this as user "henrik":

cd /test/fsdir/henrik --> works
cd /test/memdir/henrik --> fails


Here are the commands used:

<< run these as root >>
adduser henrik
adduser dummy
mkdir /test /test/fsdir /test/memdir
mount -t tmpfs tmpfs /test/memdir
cd /test/fsdir; ln -s ../../home/henrik .
cd /test/memdir; ln -s ../../home/henrik .
chown dummy:dummy /test/memdir

<< run these as user henrik >>
# This works:
cd /test/fsdir/henrik
# This fails:
cd /test/memdir/henrik


Tested on clean installs of Wheezy and Squeeze in a Virtualbox
setup, but originally found on a physical server upgraded from
Squeeze to Wheezy.

This is a feature, not a bug:

  * fs: Introduce and enable security restrictions on links:
    - Do not follow symlinks in /tmp that are owned by other users
      (sysctl: fs.protected_symlinks)

As noted, you can disable this restriction by changing the sysctl.
