Hi guys, I'm using F17 with the last ver. of Wine and Wine Tricks. When I'm trying to open an app of win, it always shows me a box:

SELinux Alert Browser

The source process:  wine-preloader

Attempted this access: mmap-zero


In details, shows me this:

SELinux is preventing wine-preloader from mmap_zero access on the memprotect .

Plugin mmap_zero (53.1 confidence) suggests *******

If no cree que wine-preloader debería necesitar realizar un mmap sobre la baja memoria en el kernel. Then podría estar siendo víctima de un ataque, este es un acceso muy peligroso. Do póngase en contacto con su administrador de seguridad y reporte este problema.

Plugin catchall_boolean (42.6 confidence) suggests ******

If desea mmaplowallowed Then you must tell SELinux about this by enabling the 'mmaplowallowed' boolean.You can read 'unconfinedselinux' man page for more details. Do setsebool -P mmaplow_allowed 1

Plugin catchall (5.76 confidence) suggests ********

If cree que de manera predeterminada, wine-preloader debería permitir acceso mmap_zero sobre memprotect.
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 wine-preloader /var/log/audit/audit.log | audit2allow -M mypol

semodule -i mypol.pp

If your app is working, then I would just dontaudit this message, If this is forcing you to run in permissive mode then set the following boolean.

setsebool -P mmaplowallowed 1

The alert told you all this. If it was me I would run my windows apps in a virtual machine and stop playing with wine. :^)
