Description of problem:
Using NVIDIA official drivers packaged by RPM Fusion
SELinux is preventing /opt/google/chrome/nacl_helper_bootstrap from 'execmod' accesses on the file /usr/lib/nvidia-304xx/libnvidia-glcore.so.304.88.

If cree que esto es causado por una maquina muy mal etiquetada.

If you want to allow nacl_helper_bootstrap to have execmod access on the libnvidia-glcore.so.304.88 file
Then necesita modificar la etiqueta en /usr/lib/nvidia-304xx/libnvidia-glcore.so.304.88
Do
# semanage fcontext -a -t FILE_TYPE '/usr/lib/nvidia-304xx/libnvidia-glcore.so.304.88'
donde FILE_TYPE es uno de los siguientes: lib_t, textrel_shlib_t. 
Luego ejecute: 
restorecon -v '/usr/lib/nvidia-304xx/libnvidia-glcore.so.304.88'


*****  Plugin catchall (5.04 confidence) suggests  ***************************

If cree que de manera predeterminada, nacl_helper_bootstrap debería permitir acceso execmod sobre  libnvidia-glcore.so.304.88 file.     
Then debería reportar esto como un error.
Puede generar un módulo de política local para permitir este acceso.
Do
permita el acceso momentáneamente executando:
# grep nacl_helper_boo /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Daniel Walsh 2013-08-01 21:28:20 EDT
file_t means you have a mislabeled file

restorecon -R -v /usr

Should fix your problem.
