Description Wayne Price 2008-02-08 12:27:55 UTC
Description of problem:
setroubleshoot browser gave warning, and suggested filing as a bug report.
Problem occurred by 'chsh' to '/bin/tcsh' for the logged in user.

SELinux prevented /sbin/unix_update from using the terminal .

Detailed Description
SELinux prevented /sbin/unix_update from using the terminal . 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 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.

Allowing Access
Changing the "allow_daemons_use_tty" boolean to true will allow this access:
"setsebool -P allow_daemons_use_tty=1.
"The following command will allow this access:setsebool -P allow_daemons_use_tty=1

You can ignore this for now, it will be dontaudit'd in the next release.

Fixed in selinux-policy-3.0.8-84.fc8
