Description Zack Cerza 2007-10-01 15:09:16 EDT
I'm guessing this was triggered by an NM crash.


    SELinux is preventing access to files with the label, file_t.

Detailed Description
    SELinux permission checks on files labeled file_t are being denied.  file_t
    is the context the SELinux kernel gives to files that do not have a label.
    This indicates a serious labeling problem. No files on an SELinux box should
    ever be labeled file_t. If you have just added a new disk drive to the
    system you can relabel it using the restorecon command.  Otherwise you
    should relabel the entire files system.

Allowing Access
    You can execute the following command as root to relabel your computer
    system: "touch /.autorelabel; reboot"

Comment 1 Zack Cerza 2007-10-01 15:10:28 EDT
I'm not sure what directory it was trying to touch, or why it was labeled
file_t, but I have done several autorelabels in the past.
Comment 2 Daniel Walsh 2007-10-01 16:21:31 EDT
Please execute

#fixfiles restore and see what happens?

Comment 3 Daniel Walsh 2007-10-09 16:52:39 EDT
autorelabel should work in selinux-policy-3.0.8-18.fc8
Comment 4 Daniel Walsh 2008-01-30 14:05:39 EST
Bulk closing a old selinux policy bugs that were in the modified state.  If the
bug is still not fixed.  Please reopen.
