Description of problem: Souhrn: SELinux prevented dbus-daemon from using the terminal /dev/tty1. Podrobný popis: SELinux prevented dbus-daemon from using the terminal /dev/tty1. In most cases daemons do not need to interact with the terminal, usually these avc messages can be ignored. All of the confined daemons should have dontaudit rules around using the terminal. Please file a bug report (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi) against this selinux-policy. If you would like to allow all daemons to interact with the terminal, you can turn on the allow_daemons_use_tty boolean. Povolení přístupu: Changing the "allow_daemons_use_tty" boolean to true will allow this access: "setsebool -P allow_daemons_use_tty=1."

Fixed in selinux-policy-3.2.7-3.fc9
The fix works for the original reporter with selinux-policy-3.2.7-3.fc9. (He sits at the next desk.) However, I have just upgraded to selinux-policy-3.2.7-4.fc9 (and rebooted), and observe an almost identical problem. The difference is that I use runlevel 3 and startx from tty6 (or tty11 or whatever). Other differences: i386, selinux-policy-3.2.7-4.fc9 The messages in audit.log are: type=AVC msg=audit(1202910517.486:49): avc: denied { read write } for pid=4768 comm="dbus-daemon" path="/dev/tty6" dev=tmpfs ino=2310 scontext=unconfined_u:unconfined_r:unconfined_dbusd_t:s0-s0:c0.c1023 tcontext=unconfined_u:object_r:unconfined_tty_device_t:s0 tclass=chr_file type=SYSCALL msg=audit(1202910517.486:49): arch=40000003 syscall=11 success=yes exit=0 a0=804c907 a1=bff4414c a2=bff45574 a3=7 items=0 ppid=4767 pid=4768 auid=10464 uid=10464 gid=10464 euid=10464 suid=10464 fsuid=10464 egid=10464 sgid=10464 fsgid=10464 tty=(none) comm="dbus-daemon" exe="/bin/dbus-daemon" subj=unconfined_u:unconfined_r:unconfined_dbusd_t:s0-s0:c0.c1023 key=(null)
(this shouldn't be a surprise: please avoid reporting selinux errors against anything but selinux packages)
Fixed in selinux-policy-3.3.1-4.fc9
CLosed as this should be fixed in rawhide. If this problem persists please reopen the bugzilla.
