Description of problem:

Souhrn:

SELinux is preventing iwconfig (ifconfig_t) "search" to ./keys (debugfs_t).

Podrobný popis:

SELinux denied access requested by iwconfig. It is not expected that this access
is required by iwconfig and this access may signal an intrusion attempt. It is
also possible that the specific version or configuration of the application is
causing it to require additional access.

Povolení přístupu:

Sometimes labeling problems can cause SELinux denials. You could try to restore
the default system file context for ./keys,

restorecon -v './keys'

If this does not work, there is currently no automatic way to allow this access.
Instead, you can generate a local policy module to allow this access - see FAQ
(http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Or you can disable
SELinux protection altogether. Disabling SELinux protection is not recommended.
Please file a bug report (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi)
against this package.

Additional info:
This happens to me on resume from suspended notebook. Actually, I don't know
what ./keys is (I haven't found anything which looks reasonably similar on the
hard disk; ls -lZ /etc/sysconfig/network-scripts/keys-wlan0 has labels
system_u:object_r:etc_t.
