            Bug ID: 43192
           Summary: Wine Staging 2.10 run afoul of SELinux
           Product: Wine-staging
           Version: 2.10
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: -unknown

Wine Staging 2.10 is annoying SELinux:

SELinux is preventing /usr/local/bin/wine-preloader from mmap_zero access on
the memprotect Unknown.

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

If you do not think /usr/local/bin/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 allow mmap to low allowed
Then you must tell SELinux about this by enabling the 'mmap_low_allowed'
boolean.
You can read 'None' man page for more details.
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
Unknown 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:
# ausearch -c 'wine-preloader' --raw | audit2allow -M my-winepreloader
# semodule -i my-winepreloader.pp
