Description ssabchew 2009-11-23 08:58:39 UTC

SELinux is preventing /usr/sbin/gpsd "sys_tty_config" access.

Detailed Description:

[SELinux is in permissive mode. This access was not denied.]

SELinux denied access requested by gpsd. It is not expected that this access is
required by gpsd and this access may signal an intrusion attempt. It is also
possible that the specific version or configuration of the application is
causing it to require additional access.

Allowing Access:

You can generate a local policy module to allow this access - see FAQ
(http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Please file a bug

Comment 1 Daniel Walsh 2009-11-23 16:58:40 UTC
You can add these rules for now using

# grep avc /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
