I`m having trouble running some games (JadeDynasty,War Of The Immortals) after I have installed them and I need to determine if this is the problem.
Is anyone famaliar with the following msg:
SELinux is preventing wine-preloader from mmap_zero access on the memprotect .
***** Plugin mmap_zero (53.1 confidence) suggests **************************
If you do not think wine-preloader should need to mmap low memory in the kernel.
Then you may be under attack by a hacker, this is a very dangerous access.
Do
contact your security administrator and report this issue.
***** Plugin catchall_boolean (42.6 confidence) suggests *******************
If you want to control the ability to mmap a low area of the address space, as configured by /proc/sys/kernel/mmap_min_addr.
Then you must tell SELinux about this by enabling the 'mmap_low_allowed'boolean.
Do
setsebool -P mmap_low_allowed 1
***** Plugin catchall (5.76 confidence) suggests ***************************
If you believe that wine-preloader should be allowed mmap_zero access on the memprotect by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep wine-preloader /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
