Description of problem: SELinux is preventing systemd-journal from 'use' accesses on the fd fd. ***** Plugin catchall_boolean (89.3 confidence) suggests ******************* If you want to allow all domains to use other domains file descriptors Then you must tell SELinux about this by enabling the 'domain_fd_use' boolean. You can read 'kernel_selinux' man page for more details. Do setsebool -P domain_fd_use 1 ***** Plugin catchall (11.6 confidence) suggests *************************** If you believe that systemd-journal should be allowed use access on the fd fd by default. Then you should report this as a bug. You can generate a local policy module to allow this access.

Yes, I disabled all the booleans to make my system more secure. But then I had to re-enable this. What does "If you want to allow all domains to use other domains file descriptors" mean? And why does systemd-journal want it to be enabled?
Fixed in selinux-policy-3.12.1-48.fc19.noarch This should be fixed with the boolean disabled. Basically this allows one confined domains to use an FD that was leaked to it by another process. In this case we do want to allow this by default. When a system boots up all processes are running as kernel_t, including the process that opens up the syslog socket, systemd then leaks this open file descriptor to sysgtemd-journald, and systemd-journald can then use it.
