Description Alberto 2009-11-28 23:27:46 UTC
Resúmen:

SELinux is preventing wine-preloader (unconfined_execmem_t) "mmap_zero" to <Unknown>
(unconfined_execmem_t).

Descripción Detallada:

[SELinux esta en modo permisivo. Este acceso no fue denegado.]

SELinux denied access requested by wine-preloader. The current boolean settings
do not allow this access. If you have not setup wine-preloader to require this
access this may signal an intrusion attempt. If you do intend this access you
need to change the booleans on this system to allow the access.

Permitiendo Acceso:

Confined processes can be configured to to run requiring different access,
SELinux provides booleans to allow you to turn on/off access as needed. The
boolean allow_unconfined_mmap_low is set incorrectly.
Boolean Description:
Allow unconfined domain to map low memory in the kernel


Comando para Corregir:

# setsebool -P allow_unconfined_mmap_low 1
