Sammanfattning:

SELinux is preventing /opt/real/RealPlayer/realplay.bin from loading
/opt/real/RealPlayer/plugins/swfrender.so which requires text relocation.

Detaljerad beskrivning:

The realplay.bin application attempted to load
/opt/real/RealPlayer/plugins/swfrender.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
/opt/real/RealPlayer/plugins/swfrender.so to use relocation as a workaround,
until the library is fixed. Please file a bug report.

Att tillåta åtkomst:

If you trust /opt/real/RealPlayer/plugins/swfrender.so to run correctly, you can
change the file context to textrel_shlib_t. "chcon -t textrel_shlib_t
'/opt/real/RealPlayer/plugins/swfrender.so'" You must also change the default
file context files on the system in order to preserve them even on a full
relabel. "semanage fcontext -a -t textrel_shlib_t
'/opt/real/RealPlayer/plugins/swfrender.so'"

Lagningskommando:

chcon -t textrel_shlib_t '/opt/real/RealPlayer/plugins/swfrender.so'
