:*****  Plugin leaks (86.2 confidence) suggests  ******************************
:
:If you want to ignore python2.7 trying to execute access the script.sh file, because you believe it should not need this access.
:Then you should report this as a bug.  
:You can generate a local policy module to dontaudit this access.
:Do
:# grep /usr/bin/python2.7 /var/log/audit/audit.log | audit2allow -D -M mypol
:# semodule -i mypol.pp

:*****  Plugin catchall (14.7 confidence) suggests  ***************************
:
:If you believe that python2.7 should be allowed execute access on the script.sh file 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 tuned /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp

Comment 1 ngativ 2012-06-21 00:47:18 UTC
I just made a tuned script using powertop2tuned.

Everytime a reboot selinux complains about the script being executed by tuned (python). And i have to "grep tuned /var/log/audit/audit.log | audit2allow -M mypol ;  semodule -i mypol.pp"

I gave up and disabled selinux

Comment 2 Miroslav Grepl 2012-06-21 05:53:47 UTC
You can fix it using

# chcon -t bin_t /etc/tuned/macbook/script.sh

Fixed in selinux-policy-3.10.0-133.fc17.noarch
