    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 ===
    open("/etc/mtab~202", O_WRONLY|O_CREAT|O_LARGEFILE, 0600audit(1085949484.378:0): avc: denied { write } for pid=202 exe=/bin/mount name=etc dev=hda5 ino=91 scontext=system_u:system_r:kernel_t tcontext=system_u:object_r:etc_t tclass=dir

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