Description Matěj Cepl 2009-08-31 19:14:44 UTC
The following was filed automatically by setroubleshoot:

Souhrn:

SELinux is preventing the iconv from using potentially mislabeled files
(/tmp/ccdmHmI6).

Podrobný popis:

SELinux has denied iconv access to potentially mislabeled file(s)
(/tmp/ccdmHmI6). This means that SELinux will not allow iconv to use these
files. It is common for users to edit files in their home directory or tmp
directories and then move (mv) them to system directories. The problem is that
the files end up with the wrong file context which confined applications are not
allowed to access.

Povolení přístupu:

If you want iconv to access this files, you need to relabel them using
restorecon -v '/tmp/ccdmHmI6'. You might want to relabel the entire directory
using restorecon -R -v '/tmp'.

Comment 1 Daniel Walsh 2009-08-31 21:30:23 UTC
What process created /tmp/ccdmHmi6?

Actually, I have no clue. I have to admit that I was more interested to find out whether sealert -s would work in the rare occasion when it seemed useful. I was preparing to file a bug against sealert (which I do now? ;-)) and tested how bad the issue is.

Comment 3 Daniel Walsh 2009-09-01 12:40:38 UTC
Try the latest setroubleshoot in rawhide,  I spent some time cleaning up the code yesterday.

Are you repeatedly seeing this error?

Comment 4 Daniel Walsh 2009-09-01 12:41:36 UTC
Dan, do  you have any idea what creates this file?
