Zusammenfassung: SELinux is preventing /usr/bin/mod_install from loading /usr/lib/libtfmessbsp.so which requires text relocation. Detaillierte Beschreibung: The mod_install application attempted to load /usr/lib/libtfmessbsp.so which requires text relocation. This is a potential security problem. Most libraries do not need this permission. Libraries are sometimes coded incorrectly and request this permission. The SELinux Memory Protection Tests (http://people.redhat.com/drepper/selinux-mem.html) web page explains how to remove this requirement. You can configure SELinux temporarily to allow /usr/lib/libtfmessbsp.so to use relocation as a workaround, until the library is fixed. Please file a bug report. Zugriff erlauben: If you trust /usr/lib/libtfmessbsp.so to run correctly, you can change the file context to textrel_shlib_t. "chcon -t textrel_shlib_t '/usr/lib/libtfmessbsp.so'" You must also change the default file context files on the system in order to preserve them even on a full relabel.

You should report this as a bug to libbiometrics that they are building their libraries incorrectly. http://people.redhat.com/~drepper/selinux-mem.html explains the problem. If you execute the command explained in the alert it should fix the problem. I will make this the default label in the next release. Fixed in selinux-policy-3.6.32-47.fc12.noarch
