Description Petr Schindler 2013-10-24 08:56:09 EDT
Description of problem:
I just booted Fedora 20 Beta TC5 Live 64b on Mac Mini
SELinux is preventing systemd-readahe from 'open' accesses on the chr_file /dev/urandom.

*****  Plugin catchall_boolean (89.3 confidence) suggests   ******************

If you want to allow global to ssp
Then you must tell SELinux about this by enabling the 'global_ssp' boolean.
You can read 'None' man page for more details.
setsebool -P global_ssp 1

*****  Plugin catchall (11.6 confidence) suggests   **************************

If you believe that systemd-readahe should be allowed open access on the urandom chr_file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# grep systemd-readahe /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
