           Summary: Debian/Ubuntu packages do not follow proper format for
                    /etc/sysctl.d
           Product: Wine
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: at at drinian.org


After reading about the recent security hole in the Linux kernel (cf.
http://linux.slashdot.org/story/09/11/04/0320254/), I decided to add a new
script to /etc/sysctl.d/ to set vm.mmap_min_addr to a non-zero value even
though I have Wine installed.

Problem is, the Wine package installs a file, /etc/sysctl.d/wine.sysctl.conf,
that does not have a numerical prefix in its file name. It will always execute
after all other files in the directory that have values like 10-*.conf,
30-*.conf, etc. This is explained in the file /etc/sysctl.d/README.

So, to make my new reset script run after Wine's script, I have to name it
something like zz.wine-undo.sysctl.conf.

Package maintainer should probably at minimum rename the file, if not find a
way to encourage users to make this security-lowering decision on their own
rather than making it the default. (Maybe a warning message from wine when
vm.mmap_min_addr is not zero?)
