Description Joseph D. Wagner 2010-08-16 08:31:08 UTC 
Summary:

SELinux is preventing /usr/sbin/ulogd "create" access .

Detailed Description:

[ulogd has a permissive type (ulogd_t). This access was not denied.]

SELinux denied access requested by ulogd. It is not expected that this access is
required by ulogd 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://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Please file a bug
report.

Comment 1 Miroslav Grepl 2010-08-16 12:54:34 UTC 
Dan,
we need to add

allow ulogd_t self:netlink_route_socket r_netlink_socket_perms;

files_read_etc_files(ulogd_t)
files_read_usr_files(ulogd_t)

optional_policy(`
