Description of problem:
The Gizmo third-party application does not run since SELinux tragetted policy is
denying the use of the libsipphoneapi library.

[mwiktowy@localhost ~]$ gizmo
gizmo: error while loading shared libraries: /usr/lib/libsipphoneapi.so: cannot
restore segment prot after reloc: Permission denied

Looking at the /var/log/messages:

Apr  1 20:11:49 localhost kernel: audit(1143940309.555:15): avc:  denied  {
execmod } for  pid=2228 comm="gizmo" name="libsipphoneapi.so.0.78.20060211"
dev=hda2 ino=3713363 scontext=user_u:system_r:unconfined_t:s0
tcontext=system_u:object_r:lib_t:s0 tclass=file

Looking at the permissions and contexts:

[root@localhost ~]# ls -la /usr/lib/libsipphoneapi.so.0.78.20060211
-rw-r--r-- 1 root root 33064270 Feb 11 15:08
/usr/lib/libsipphoneapi.so.0.78.20060211

[root@localhost ~]# ls -laZ /usr/lib/libsipphoneapi.so.0.78.20060211 -rw-r--r--
 root     root     system_u:object_r:lib_t         
/usr/lib/libsipphoneapi.so.0.78.20060211

If I use the boot switch enforcing=0, Gizmo will run fine.

Research at in the execmod section of
http://fedora.redhat.com/docs/selinux-faq-fc5/ suggested assigning the context
using:
chcon -t testrel_shlib_t LIBRARY
where I replaced LIBRARY with /usr/lib/libsipphoneapi.so.0.78.20060211

and reporting to bugzilla.

However, that did not work as I would assume that context was enabled only for
test releases.

The libsipphone library is obtained here:
