Description Sebastiano M. Cossu 2009-09-20 15:33:51 UTC
The following was filed automatically by setroubleshoot:


SELinux is preventing /usr/bin/wine-preloader "mmap_zero" access on <Unknown>.

Descrizione dettagliata:

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.

Abilitazione accesso in corso:

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

Comando fix:

# setsebool -P mmap_low_allowed 1
