Subject2.6.7-rc2: open() hangs on ReiserFS with SELinux enabled
From
Hello,

I tried enabling SELinux on my Linux-box, using ReiserFS as /, kernel
2.6.7-rc2.

After relabeling and rebooting in non-enforcing mode everything worked
well, exept the fact, that new files on reiserfs filesystems don't get
security attributes.

So I added 'fs_use_xattr reiserfs system_u:object_r:fs_t;' to the policy,
rebooted and found, that mount hangs during opening of /etc/mtab~<pid>
(even in non-enforcing mode).

If I remove that line from SELinux policy, systems boots up OK.

Here are last lines from #strace mount / -o remount :

=== Cut ===

Tell me, if I need to provide any additional info.
